Decompressive craniectomy and expansive duraplasty with evacuation of hypertensive intracerebral hematoma,a randomized controlled trial

Hypertensive intracerebral hemorrhage (ICH) has high morbidity and mortality rates. Decompressive craniectomy (DC) is generally used for the treatment of cases associated with refractory increased intracranial pressure (ICP). In this study, we investigated the beneficial effects of adding DC and expansive duraplasty (ED) to hematoma evacuation in patients who underwent surgery for large hypertensive ICH. A prospective randomized controlled clinical trial where 40 patients diagnosed having large hypertensive ICH was randomly allocated to either group A or B, each comprised 20 patients. Group A patients, the treatment group, were submitted to hematoma evacuation together with DC and ED, whereas group B patients, the control group, were submitted only to hematoma evacuation. Twenty-three (57.5 %) of the patients were males, with an overall age range of 34–79 years (mean 59.3 years). Preoperative Glasgow Coma Scale (GCS) scores in group A ranged from 4 to 13 (mean 7.1), while in group B it ranged from 4 to 12 (mean 6.8). Postoperative hydrocephalus occurred in 3 (15 %) patients in group A and in 4 (20 %) patients in group B, whereas meningitis occurred in one patient (5 %) in group A. The mortality rate was 2 (10 %) patients in group A as compared to 5 (25 %) patients in group B (p?=?0.407). High admission GCS (p?=?0.0032), younger age (p?=?0.0023), smaller hematoma volume (p?=?0.044), subcortical hematoma location (p?=?0.041), absent or minimal preoperative (p?=?0.0068), and postoperative (p?=?0.0031) midline shift as well as absent intraventricular extension of the hematoma (p?=?0.036) contributed significantly to a better outcome. Selected patients’ subgroups who benefited from adding DC and ED to ICH evacuation were age category of 30 to less than 50 (p?=?0.0015) and from 50 to less than 70 (p?=?0.00619) as well as immediate preoperative GCS from 6 to 8 (p?=?0.000436) and from 9 to 12 (p?=?0.00774). At 6 months’ follow-up, 14 (70 %) patients of group A had favorable outcome as compared to 4 (20 %) patients of group B (p?=?0.0015). Adding DC with ED to evacuation of a large hypertensive hemispheric ICH might improve the outcome in selected group of patients.     

The value of the Charlson Co-morbidity Index in aneurysmal subarachnoid haemorrhage

Background

Several studies have included different co-morbid conditions in prediction models for stroke patients. For subarachnoid haemorrhage (SAH), it is not known whether the Charlson Co-morbidity Index (CCI) is associated with outcome. We evaluated if this index was associated with outcome in patients with ruptured intracerebral aneurysms.

Methods

The data of all consecutive aneurysmal SAH (aSAH) patients treated at the Radboudumc, Nijmegen, The Netherlands and entered in the database were retrospectively analysed. Clinical condition at admission was recorded using the WFNS (World Federation of Neurological Surgeons Grading System) grade was collected, as were the age and treatment modality. The burden of co-morbidity was retrospectively registered using the CCI. Outcome was dichotomised on the modified Rankin Scale (mRS; 0–2, favourable outcome; 3–6, unfavourable outcome). A binary logistic regression analysis was performed.

Results

Between 6th May 2008 and 31st July 2013, 457 patients were admitted because of non-traumatic SAH (aSAH). Seventy-seven (16.8 %) patients had no aneurysm. Of the 380 patients with aSAH, information on co-morbid conditions was available for 371 patients. Thirty-six of those 371 had no treatment because of: bad clinical condition in 34 (9.2 %), a non-treatable dissecting aneurysm in 1 (0.3 %) and the explicit wishes of another. Co-morbidity was present in 113 (31.5 %) patients. Binary logistic regression analysis revealed no added value of using the CCI in predicting the outcome (p?=?0.91).

Conclusions

This study reports that the CCI is not associated with the outcome classified on the mRS at 6 months in patients after aSAH. The CCI has no added value in case-mix correction.     

Outcome after severe brain trauma associated with epidural hematoma

Objective

The aim of this study was to identify factors contributing to outcomes after severe traumatic brain injury (TBI) associated with epidural hematoma (EDH).

Methods

Between 02/2002 and 4/2010 17 Austrian centers prospectively enrolled 863 patients with moderate and severe TBI into observational studies. Data on accident, treatment, and outcomes were collected. Data sets from patients who had severe TBI (=Glasgow Coma Scale score <9) and EDH were selected. Six-month outcomes were classified as “favorable” if Glasgow Outcome Scale (GOS) scores were 5 or 4, and were classified as “unfavorable” if GOS scores were 3 or less. The Rotterdam score was used to classify computed tomography (CT) findings; the scores published by Hukkelhoven et al. (J Neurotrauma 22:1025–1039, 2005) were used to estimate predicted rates of death and of unfavorable outcomes. Univariate (Fisher’s exact test, t test, Chi²-test) and multivariate (logistic regression) statistics were used to identify factors associated with hospital mortality and favorable outcome.

Results

Of the 738 patients with severe TBI 159 (21.5 %) had EDH. Of these, 49 (30.8 %) died in the hospital, 21 (13.2 %) survived with unfavorable outcome, 82 (51.6 %) with favorable outcome; long-term outcome was unknown in 7 survivors (4.4 %). Mortality rates predicted by the Rotterdam score showed good correlation with observed mortality rates. According to the Hukkelhoven scores, observed/predicted ratios for mortality and unfavorable outcome were 0.94 and 0.97, respectively. Age, severity of TBI, and neurological status were the main factors influencing outcomes after severe TBI associated with EDH. We were unable to demonstrate significant effects of treatment factors.     

Predicting the overall management outcome in patients with a subarachnoid hemorrhage accompanied by a massive intracerebral or full-packed intraventricular hemorrhage: a 15-year retrospective study

BACKGROUND: Patients with a subarachnoid hemorrhage (SAH) accompanied by a massive intracerebral hemorrhage (ICH) or a full-packed intraventricular hemorrhage (IVH) have poor outcomes. We evaluated the clinical factors to predict the overall outcome in such patients. METHODS: Data on nontraumatic SAH patients were collected and classified into 3 groups: the pure SAH group (SAH accompanied with neither ICH nor IVH), the ICH group (SAH accompanied with a massive ICH; hematoma 30 mL), and the IVH group (SAH and all ventricles were full-packed with hematoma). One hundred seventy-nine patients were in the ICH group and 109 in the IVH group. We evaluated clinical factors, such as the Hunt & Hess (H&H) score on admission, age, sex, history, rebleeding ratio, and the computerized tomography findings (SAH score). RESULTS: The result of multivariate logistic regression analysis of clinical variables in the ICH group, good and intermediate H&H grades, younger age (<70), no rebleeding, and lower SAH score were associated with a favorable outcome. In the result of the multivariate logistic regression analysis of clinical variables in the IVH group, only a higher SAH score was associated with an unfavorable outcome. CONCLUSIONS: In the ICH group, factors that could be used to predict a favorable outcome included good and intermediate H&H scores (1, 2, and 3) on admission, younger age (<70), and a lower SAH score. In the IVH group, the main factor that could be used to predict a favorable outcome was a lower SAH score.     

Surgical treatment of intraparenchymal hemorrhage during mechanical circulatory support for heart-failure – a single-centre experience

Background

Cranial intraparenchymal hemorrhage represents a critical complication of mechanical circulatory support requiring constant antithrombotic treatment. Surgery of intraparenchymal hemorrhage under anticoagulation represents a challenge and imposes significant risks for patients. It was the aim to analyse surgical and clinical outcome of patients requiring surgical treatment due to intraparenchymal hemorrhage.

Methods

Patients with mechanical circulatory support requiring surgical therapy due to space-occupying lobar supratentorial or infratentorial hemorrhage from January 1, 2009 to January 1, 2014 were included in our study. Baseline parameters are preoperative International Normalized Ratio (INR) values, postoperative anticoagulation regiment, bleeding size and localization. Co-primary outcome parameters were the extent of hematoma evacuation and the Modified Rankin Scale at discharge from hospital. Secondary outcome parameters included rate of recurrent hemorrhage, rate of revision surgery and in-hospital mortality.

Results

Twelve patients (mean age 44?±?18 years, nine supratentorial-/three infratentorial hemorrhages, 11 left ventricular assist devices, and one extracorporeal membrane oxygenation) were included. Surgical hematoma evacuation was performed in 11 patients, one patient received decompressive hemicraniectomy. Hematoma evacuation was complete in no patients, and partial in 11 patients. Initial INR was 2,7?±?1,6. Rate of recurrent hemorrhage was 75 %. Revision surgery was performed in three patients achieving partial hematoma evacuation in two patients and complete evacuation in one patient. Modified Rankin Scale at discharge from hospital was six in nine patients (in-hospital mortality of 75 %), five in two patients and four in one patient.

Conclusions

Surgical treatment of life threatening, space-occupying intraparenchymal hemorrhage under mechanical circulation support is of limited efficacy with high rates of recurrent hemorrhage and in-hospital mortality. We provide additional data that postponing anticoagulation is feasible and may lead to improved clinical outcome and survival.     

Primary intracerebral and aneurysmal subarachnoid hemorrhage in Izumo City, Japan. Part II: management and surgical outcome

OBJECT: The purpose of this study was to assess the overall management and surgical outcome of primary intracerebral hemorrhage (ICH) and aneurysmal subarachnoid hemorrhage (SAH) among the 85,000 residents of Izumo City, Japan. METHODS: During 1991 through 1996, 267 patients with ICH and 123 with SAH were treated in Izumo. Of the 267 patients with ICH, 25 underwent hematoma removal by open craniotomy or suboccipital craniectomy and 34 underwent stereotactic evacuation of the hematoma, whereas aneurysm clipping was performed in 71 of the 123 patients with SAH; operability rates were thus 22% for ICH and 58% for SAH (p < 0.0001). The overall 30-day survival rates were 86% for ICH and 66% for SAH (p < 0.0001) and the 2-year survival rates were 73% and 62% (p = 0.0207), respectively. In patients who underwent surgery, 30-day and 2-year survival rates were 93% for ICH and 100% for SAH (p = 0.0262), and 75% for ICH and 97% for SAH (p = 0.0002), respectively. In patients with ICH, the most important predictors of 30-day case-fatality rates were the volume of the hematoma, the Glasgow Coma Scale (GCS) score, rebleeding, and midline shifting, whereas those for 2-year survival were the GCS score, age, rebleeding, and hematoma volume. In patients with SAH, the most important determinants of 30-day case-fatality rates were the GCS score and age, whereas only the GCS score had a significant impact on 2-year survival. CONCLUSIONS: The overall survival rates for patients with ICH or SAH in Izumo were more favorable than those in previously published epidemiological studies. However, despite improved surgical results, the overall management of ICH and SAH still produced an unsatisfactory outcome, mainly because of primary brain damage.     

Clinical features and management of intracranial hemorrhage in patients undergoing maintenance dialysis therapy

The management and outcome were retrospectively investigated in patients with chronic renal failure receiving maintenance blood purification who suffered intracranial hemorrhage. Patients with intracerebral hemorrhage (ICH, n = 36) or subarachnoid hemorrhage (SAH, n = 5) were evaluated. Both groups were initially managed using continuous hemofiltration (HF) after admission, except for two patients with SAH receiving maintenance peritoneal dialysis. Patients with ICH were managed with HF three times a week after computed tomography showed decreased peripheral edema. Nafamostat mesilate was used as the anticoagulant for both continuous HF and HF. Hemodialysis (HD) three times a week was initiated after confirming the absence of neurological deterioration using HF. Craniotomy was not performed in any patient with ICH, but if necessary, the hematoma was aspirated using burr-hole surgery. Angiography was performed on the day of admission in patients with SAH. Delayed neck-clipping surgery was performed after continuous HF for 2 weeks with lumbar cerebrospinal fluid drainage. In patients with ICH, continuous HF was continued for 2-9 days after admission (mean 5.2 +/- 2.2 days), followed by 2-9 courses of HF (mean 4.7 +/- 2.1 courses). HD was initiated 9-26 days after admission (mean 15.5 +/- 4.6 days). Favorable outcomes were achieved by 13 of the 36 patients with ICH and two of the five patients with SAH, whereas 22 patients with ICH and three patients with SAH died. Death occurred in 12 of 16 patients with ICH and diabetic nephropathy. In contrast, 10 of 20 non-diabetic patients with ICH had favorable outcomes. Ten of the 16 patients with initial GCS < or = 8 and six of the 20 with GCS > or = 9 were diabetic. Therefore, there were significant differences between diabetic and non-diabetic patients (p = 0.05). Poor outcomes in diabetic patients with ICH are caused by primary brain damage, reflected in the initial disturbance of consciousness.     

Risks and benefits of CT angiography in spontaneous intracerebral hemorrhage

Background

Few studies have examined the risk of computed tomography angiography (CTA) during the acute phase of spontaneous intracerebral hemorrhage (ICH), while the benefits of CTA in ICH have been well-documented. The present study investigated both the benefits of identifying spot signs, which are supposed to indicate hematoma enlargement after admission, and risks of CTA performed during the acute phase of ICH.

Methods

We retrospectively assessed 323 consecutive patients with spontaneous ICHs admitted to our hospital between April 2009 and March 2012 and who underwent CTA on admission.

Results

In 80 patients (24.7 %), spot signs were demonstrated on CTA source images. Multivariate analysis revealed two independent factors correlated with presence of the spot sign: age and hematoma volume (p?<?0.05 each). The presence of spot sign was associated with unfavorable outcomes at discharge and hematoma growth after admission (p?<?0.05 each). Adverse events related to CTA occurred in 17 patients (5.2 %), including transient renal dysfunction in 16 patients and allergy to contrast medium in one patient. All adverse events completely resolved within 1 week.

Conclusions

Presence of the spot sign indicated the possibility of hematoma growth and unfavorable outcomes. A small number of adverse events occurred in association with CTA, but without any permanent deficits. Given the potential benefits and risks, we believe that CTA performed at admission in all patients with ICH is beneficial to improve the outcomes.     

Bilateral Traumatic Intracranial Hematomas and its Outcome: a Retrospective Study

The objective of this study was to evaluate the age distribution, mode of injury, type of hematomas, and their surgical outcome in patients with bilateral traumatic head injuries. The present study included 669 cases of traumatic head injury who presented at the neurosurgery emergency out of which 94 cases had bilateral head injuries from the period of August 2009 to April 2014. The data from the hospital computerized database were retrospectively analysed. Cases of bilateral traumatic head injury included 94 patients out of which 88.29 % (n?=?83) were males and 11.70 % (n?=?11) were females. Commonest mode of injury was road traffic accident in 56.38 % (n?=?53) followed by fall from height in 29.78 % (n?=?28). In our study, 25.53 % patients had epidural hematoma (EDH) with intracerebral hematoma (ICH) or contusion (n?=?24), followed by EDH with subarachnoid hemorrhage (SAH) in 18.08 % (n?=?17). At the time of discharge, all those patients managed conservatively had good Glasgow outcome scale (GOS) while with surgical intervention 58 % patients had good GOS, 19 % had moderate disability, and 9 % remained with severe disability. In cases of bilateral hematomas, EDH is most common and should be managed in neurosurgical emergency. Other combinations of bilateral intracranial hematomas should be managed according to the surgical indication and serial CT imaging.     

Prospective Assessment of Trocar-Specific Morbidity in Laparoscopy

Background

The purpose of the present study was to challenge the hypothetical advantage of single port laparoscopy (SPL) over conventional laparoscopy by measuring prospectively the morbidity specifically related to conventional trocar sites (TS).

Methods

From November 2010 to December 2011, 300 patients undergoing various laparoscopic procedures were enrolled. Patient, surgery, and trocar characteristics were recorded. We evaluated at three time points (in-hospital and at 1 and 6 months postoperatively) specifically for each TS, pain (Visual Analog Scale), morbidity (infection, hematoma, hernia), and cosmesis (Patient Scar Assessment Score; PSAS). Patients designated their “worst TS,” and a composite endpoint “bad TS” was defined to include any adverse outcome at a TS.

Results

We analyzed 1,074 TS. Follow-up was >90 %. Pain scores of >3/10 at 1 and 6 months postoperatively, were reported by 3 and 1 % of patients at the 5 mm TS and by 9 and 1 % at the larger TS, respectively (5 mm TS vs larger TS; p = 0.001). Pain was significantly lower for TS located in the lower abdomen than for the upper abdomen or the umbilicus (p = 0.001). The overall complication rate was <1 % and significantly lower for the 5 mm TS (hematoma p = 0.046; infection p = 0.0001). No hernia was found. The overall PSAS score was low and significantly lower for the 5 mm TS (p = 0.0001). Significant predictors of “bad TS” were larger TS (p = 0.001), umbilical position (p = 0.0001), emergency surgery (p = 0.0001), accidental trocar exit (p = 0.022), fascia closure (p = 0.006), and specimen extraction site (p = 0.0001).

Conclusions

Specific trocar morbidity is low and almost negligible for 5 mm trocars. The umbilicus appears to be an unfavorable TS.     

Surgery for contralateral acute epidural hematoma following acute subdural hematoma evacuation: five new cases and a short literature review

Background

The occurrence of a contralateral acute epidural hematoma (AEDH) following removal of an acute subdural hematoma (ASDH) is a rare but nearly devastating postoperative complication. Here, we describe a series of five patients with contralateral AEDH and provide a review of the literature to elucidate the characteristics and improve management of these patients.

Methods

A total of 386 patients underwent ASDH evacuations in our hospital between August 2008 and July 2011. Five of these patients (1.3 %) developed AEDH that required surgery. Thirty-two additional patients were identified by a search of the PubMed database. Clinical features, surgical treatment, and outcomes (scored by Glasgow outcome scale, GOS) of the collective 37 AEDH cases were analyzed retrospectively.

Results

Contralateral AEDH after ASDH evacuation occurred in 27 males (73 %) and 10 females (27 %) (mean age: 35.9?±?14.2 years). Twenty-six patients (70 %) had unfavorable outcomes (GOS 1–3), and 11 patients (30 %) had favorable outcomes (GOS 4–5). Contralateral skull fractures and intraoperative acute brain swelling occurred in 30 (81 %) and 28 (76 %) patients, respectively. The preoperative Glasgow coma score (GCS) was significantly associated with outcome (p?<?0.05).

Conclusions

Lower preoperative GCS score is an independent risk factor for prognosis of contralateral AEDH after ASDH. Postoperative management should include assessment of AEDH in patients treated for contralateral skull fractures and who experienced intraoperative acute brain swelling. We recommend early decompression with a burr-hole craniotomy, immediately followed by a decompressive craniectomy. This strategy provides gradual decompression, while advancing the initial surgical time and preventing the suddle decreased tamponade effect. As such, it may help decrease the risk of contralateral AEDH associated with decompression.     

Visual field findings after a ruptured intracranial aneurysm

Background

Visual field defects (VFDs) negatively affect activities of daily living and rehabilitation following aneurysmal subarachnoid haemorrhage (aSAH). The aim here was to assess VFDs in patients with aSAH and their associations with age, gender, aSAH severity, and clinical outcome.

Methods

Patients admitted to Helsinki University Central Hospital and treated during 2011 were participants in this prospective study. Findings obtained with the Octopus 900 perimeter (Haag-Streit Inc, Koenic, Switzerland), the Goldmann perimeter (Haag-Streit Inc, Bern, Switzerland), or the confrontation visual field test on admission and 3 days, 14 days, 2 to 4 months, and 6 months postoperatively were assigned to 16 classes. Associations between post-chiasmal VFDs and relevant clinical, radiological, and demographic data were analysed with uni- and multivariate logistic regression.

Results

Of 105 survivors at 6 months, 20 (19 %) had VFDs occurring for aneurysm- or operation-related reasons; homonymous hemianopias or quadrantanopias were the most common finding, occurring in 16 patients (15 %). Posterior ischaemic optic neuropathy presented in two patients (2 %). Ten survivors (10 %) no longer fulfilled visual field requirements for driving licences. Significant associations emerged between VFDs at 6 months and the Hunt and Hess (H&H), World Federation of Neurosurgical Societies (WFNS), and Fisher grades on admission, presence of intracerebral haemorrhage (ICH), hydrocephalus, or postoperative infarction, and higher modified Rankin Scale scores at 6 months. Multivariate logistic regression showed the H&H grade and presence of ICH to independently predict VFDs.

Conclusions

Assessing VFDs is advisable, especially among patients with poor-grade aSAH (H&H grade IV or V) and ICH.     

Impact of concomitant injuries on outcomes after traumatic brain injury

Background

Patients with traumatic brain injury (TBI) frequently have concomitant injuries; we aimed to investigate their impact on outcomes.

Methods

Between February 2002 and April 2010, 17 Austrian centers prospectively enrolled 863 patients with moderate and severe TBI into observational studies. Data on accident, treatment, and outcomes were collected. Patients who survived until intensive care unit (ICU) admission and had survivable TBI were selected, and were assigned to “isolated TBI” or “TBI + injury” groups. Six-month outcomes were classified as “favorable” if Glasgow Outcome Scale (GOS) scores were five or four, and were classified as “unfavorable” if GOS scores were three or less. Univariate statistics (Fisher’s exact test, t test, χ²-test) and logistic regression were used to identify factors associated with hospital mortality and unfavorable outcome.

Results

Of the 767 patients, 403 (52.5 %) had isolated TBI, 364 (47.5 %) had concomitant injuries. Patients with isolated TBI had higher mean age (53 vs. 44 years, P = 0.001); hospital mortality (30.0 vs. 27.2 %, P = 0.42) and rate of unfavorable outcome (50.4 vs. 41.8 %, P = 0.02) were higher, too. There were no significant mortality differences for factors like age groups, trauma mechanisms, neurologic status, CT findings, or treatment factors. Concomitant injuries were associated with higher mortality (33.3 vs. 12.5 %, P = 0.05) in patients with moderate TBI, and were significantly associated with more ventilation, ICU, and hospitals days. Logistic regression revealed that age, Glasgow Coma Scale score, pupillary reactivity, severity of TBI and CT score were the main factors that influenced outcomes.

Conclusions

Concomitant injuries have a significant effect upon the mortality of patients with moderate TBI. They do not affect the mortality in patients with severe TBI.

Safety and efficacy of a new procedure for treating traumatic iliopsoas hematoma: a retroperitoneoscopic approach

Background

Surgical treatment is often recommended for traumatic iliopsoas hematoma. Open surgeries lead to severe surgical trauma, and minimally invasive surgeries cannot completely remove the hematoma. A new treatment protocol for traumatic iliopsoas hematoma by retroperitoneoscopic approach has been introduced. The goal of this study was to determine the safety and efficacy of retroperitoneoscopic approach used to remove iliopsoas hematoma.

Methods

Between January 2009 and July 2012, 13 patients were diagnosed of traumatic iliopsoas hematoma. Retroperitoneoscopic surgeries were performed on all patients to remove the hematomas after admission. The size of hematoma, VASA score and neurologic status were dynamic evaluated before and after surgery. Soft tissue damage and complications caused by retroperitoneoscopic approach also were recorded and evaluated.

Results

We performed retroperitoneoscopic surgery to remove traumatic iliopsoas hematoma successfully on 13 patients without complications. The mean procedure time was 52.5 ± 13.4 min, and mean blood loss was 30.7 ± 9.2 ml. Hematoma was completely removed confirmed by ultrasound after surgery. Pain in the affected lower abdominal and thigh immediately was relieved totally for ten patients and partly for three patients after surgery. Quadriceps strength was restored to grade 5 and pain completely disappeared 2 months postoperatively on all patients. Numbness along the femoral nerve distribution disappeared for 11 patients and improved for 2 patients until the last follow-up. None of 13 patients suffered from infection or a new hematoma during follow-up.

Conclusions

Retroperitoneoscopic approach is a safe and effective procedure alternative to conventional surgical approach for treating traumatic iliopsoas hematoma in terms of complete removal of hematoma, minimal invasiveness, absence of radiation, and rapid recovery.     

Glasgow Coma Scale score at intensive care unit discharge predicts the 1-year outcome of patients with severe traumatic brain injury

Objective

To analyse the association between the Glasgow Coma Scale (GCS) score at intensive care unit (ICU) discharge and the 1-year outcome of patients with severe traumatic brain injury (TBI).

Design

Retrospective analysis of prospectively collected observational data.

Patients

Between 01/2001 and 12/2005, 13 European centres enrolled 1,172 patients with severe TBI. Data on accident, treatment and outcomes were collected. According to the GCS score at ICU discharge, survivors were classified into four groups: GCS scores 3–6, 7–9, 10–12 and 13–15. Using the Glasgow Outcome Scale (GOS), 1-year outcomes were classified as “favourable” (scores 5, 4) or “unfavourable” (scores <4). Factors that may have contributed to outcomes were compared between groups and for favourable versus unfavourable outcomes within each group.

Main results

Of the 538 patients analysed, 308 (57 %) had GCS scores 13–15, 101 (19 %) had scores 10–12, 46 (9 %) had scores 7–9 and 83 (15 %) had scores 3–6 at ICU discharge. Factors significantly associated with these GCS scores included age, severity of trauma, neurological status (GCS, pupils) at admission and patency of the basal cisterns on the first computed tomography (CT) scan. Favourable outcome was achieved in 74 % of all patients; the rates were significantly different between GCS groups (93, 83, 37 and 10 %, respectively). Within each of the GCS groups, significant differences regarding age and trauma severity were found between patients with favourable versus unfavourable outcomes; neurological status at admission and CT findings were not relevant.

Conclusion

The GCS score at ICU discharge is a good predictor of 1-year outcome. Patients with a GCS score <10 at ICU discharge have a poor chance of favourable outcome.     

The Extent of Soft Tissue and Musculoskeletal Injuries after Earthquakes; Describing a Role for Reconstructive Surgeons in an Emergency Response

Background

Earthquakes are the leading cause of natural disaster-related mortality and morbidity. Soft tissue and musculoskeletal injuries are the predominant type of injury seen after these events and a major reason for admission to hospital. Open fractures are relatively common; however, they are resource-intense to manage. Appropriate management is important in minimising amputation rates and preserving function. This review describes the pattern of musculoskeletal and soft-tissue injuries seen after earthquakes and explores the manpower and resource implications involved in their management.

Methods

A Medline search was performed, including terms “injury pattern” and “earthquake,” “epidemiology injuries” and “earthquakes,” “plastic surgery,” “reconstructive surgery,” “limb salvage” and “earthquake.” Papers published between December 1992 and December 2012 were included, with no initial language restriction.

Results

Limb injuries are the commonest injuries seen accounting for 60 % of all injuries, with fractures in more than 50 % of those admitted to hospital, with between 8 and 13 % of these fractures open. After the first few days and once the immediate lifesaving phase is over, the management of these musculoskeletal and soft-tissue injuries are the commonest procedures required.

Conclusions

Due to the predominance of soft-tissue and musculoskeletal injuries, plastic surgeons as specialists in soft-tissue reconstruction should be mobilised in the early stages of a disaster response as part of a multidisciplinary team with a focus on limb salvage.     

Predictors of hematoma enlargement in patients with intracerebral hemorrhage treated with rapid administration of antifibrinolytic agents and strict blood pressure control

OBJECT: Hematoma enlargement is a major cause of poor outcome in patients with intracerebral hemorrhage (ICH). A combination of rapid administration of antifibrinolytics and strict blood pressure (BP) control for prevention of hematoma enlargement has been recently reported. The authors examined the incidence and predictors of hematoma enlargement in patients with ICH who were treated with this therapy. METHODS: Rapid administration of antifibrinolytic agents consisted of intravenous administration of 2 g tranexamic acid over 10 minutes. Systolic BP was strictly maintained below 150 mm Hg using intravenous nicardipine. Immediately after diagnosis of ICH on computed tomography (CT), 188 patients who were admitted within 24 hours of symptom onset were treated with a combination of rapid administration of antifibrinolytic agents and BP control. Hematoma enlargement was determined on the basis of a second CT scan performed the day after admission. Several factors, including those that have been reported to affect hematoma enlargement, were compared between patients with and without hematoma enlargement. Hematoma enlargement (> or =20% volume increase) was observed in eight (4.3%) of 188 patients. Previous use of antiplatelet agents was significantly more frequent in patients with hematoma enlargement (p < 0.05). No significant between-group difference was found for any other factors Conclusions. Previous use of antiplatelet agents was a predictor of hematoma enlargement in patients with ICH treated with rapid administration of antifibrinolytic agents and BP control.     

Risk factors associated with the progression of extra-axial hematoma in the original frontotemporoparietal site after contralateral decompressive surgery in traumatic brain injury patients

Purpose:To introduced our experience with progressive extra-axial hematoma(EAH)in the original frontotemporoparietal(FTP)site after contralateral decompressive surgery(CDS)in traumatic brain injury patients and discuss the risk factors associated with this dangerous situation.Methods:This retrospective study was conducted on 941 patients with moderate or severe TBI treated in Daping Hospital,Army Medical University,Chongqing,China in a period over 5 years(2013e2017).Only patients with bilateral lesion,the contralateral side being the dominant lesion,and decompressive surgery on the contralateral side conducted firstly were included.Patients were exclude if(1)they underwent bilateral decompression or neurosurgery at the original location firstly;(2)although surgery was performed first on the contralateral side,surgery was done again at the contralateral side due to rebleeding or complications;(3)patients younger than 18 years or older than 80 years;and(4)patients with other significant organ injury or severe disorder or those with abnormal coagulation profiles.Clinical and radiographic variables reviewed were demographic data,trauma mechanisms,neurological condition assessed by Glasgow coma scale(GCS)score at admission,pupil size and reactivity,use of mannitol,time interval from trauma to surgery,Rotterdam CT classification,type and volume of EAH,presence of a skull fracture overlying the EAH,status of basal cistern,size of midline shift,associated brain lesions and types,etc.Patients were followed-up for at least 6 months and the outcome was graded by Glasgow outcome scale(GOS)score as favorable(scores of 4e5)and unfavorable(scores of 1e3).Student's t-test was adopted for quantitative variables while Pearson Chi-squared test or Fisher's exact test for categorical variables.Multivariate logistic regression analysis was also applied to estimate the significance of risk factors.Results:Initially 186 patients(19.8%)with original impact locations at the FTP site and underwent surgery were selected.Among them,66 met the inclusion and exclusion criteria.But only 50 patients were included because the data of the other 16 patients were incomplete.Progressive EAH developed at the original FTP site in 11 patients after the treatment of,with an incidence of 22%.Therefore the other 39 patients were classified as the control group.Multivariate logistic regression analysis showed that both the volume of the original hematoma and the absence of an apparent midline shift were significant predictors of hematoma progression after decompressive surgery.Patients with fracture at the original impact site had a higher incidence of progressive EAH after CDS,however this factor was not an important predictor in the multivariate model.We also found that patients with progressive EAH had a similar favorable outcome with control group.Conclusion:Progressive EAH is correlated with several variables,such as hematoma volumes
10 mL at the original impact location and the absence of an apparent midline shift(<5 mm).Although progressive EAH is devastating,timely diagnosis with computed tomography scans and immediate evacuation of the progressive hematoma can yield a favorable result.
