Pneumonia as Comorbidity in Chronic Obstructive Pulmonary Disease (COPD). Differences Between Acute Exacerbation of COPD and Pneumonia in Patients With COPD

IntroductionPneumonia is considered an independent entity in chronic obstructive pulmonary disease (COPD), to be distinguished from an infectious exacerbation of COPD. The aim of this study was to analyze the clinical characteristics and progress of the exacerbation of COPD (ECOPD) compared to pneumonia in COPD (PCOPD) patients requiring hospitalization.Patients and methodsProspective, longitudinal, observational cohort study including 124 COPD patients requiring hospital admission for lower respiratory tract infection. Patients were categorized according to presence of ECOPD (n=104) or PCOPD (n=20), depending on presence of consolidation on X-ray. Demographic, clinical, laboratory, microbiological and progress variables were collected.ResultsPatients with ECOPD showed more severe respiratory disease according to the degree of obstruction (P<.01) and need for oxygen therapy (P<.05). PCOPD patients showed increased presence of fever (P<.05), higher blood pressure (P<.001), more laboratory abnormalities (P<.05; leukocytosis, elevated CRP, low serum albumin) and increased presence of crepitus (P<.01). Microbiological diagnosis was achieved in 30.8% of cases of ECOPD and 35% of PCOPD; sputum culture yielded the highest percentage of positive results, predominantly Pseudomonas aeruginosa. Regarding the progress of the episode, no differences were found in hospital stay, need for ICU or mechanical ventilation.ConclusionsOur data confirm clinical and analytical differences between ECOPD and PCOPD in patients who require hospital admission, while there were no differences in subsequent progress.     

Bedside tracer gas technique accurately predicts outcome in aspiration of spontaneous pneumothorax

BACKGROUND: There is no technique in general use that reliably predicts the outcome of manual aspiration of spontaneous pneumothorax. We have hypothesised that the absence of a pleural leak at the time of aspiration will identify a group of patients in whom immediate discharge is unlikely to be complicated by early lung re-collapse and have tested this hypothesis by using a simple bedside tracer gas technique. METHODS: Eighty four episodes of primary spontaneous pneumothorax and 35 episodes of secondary spontaneous pneumothorax were studied prospectively. Patients breathed air containing a tracer (propellant gas from a pressurised metered dose inhaler) while the pneumothorax was aspirated percutaneously. Tracer gas in the aspirate was detected at the bedside using a portable flame ioniser and episodes were categorised as tracer gas positive (>1 part per million of tracer gas) or negative. The presence of tracer gas was taken to imply a persistent pleural leak. Failure of manual aspiration and the need for a further intervention was based on chest radiographic appearances showing either failure of the lung to re-expand or re-collapse following initial re-expansion. RESULTS: A negative tracer gas test alone implied that manual aspiration would be successful in the treatment of 93% of episodes of primary spontaneous pneumothorax (p<0.001) and in 86% of episodes of secondary spontaneous pneumothorax (p=0.01). A positive test implied that manual aspiration would either fail to re-expand the lung or that early re-collapse would occur despite initial re-expansion in 66% of episodes of primary spontaneous pneumothorax and 71% of episodes of secondary spontaneous pneumothorax. Lung re-inflation on the chest radiograph taken immediately after aspiration was a poor predictor of successful aspiration, with lung re-collapse occurring in 34% of episodes by the following day such that a further intervention was required. CONCLUSIONS: National guidelines currently recommend immediate discharge of patients with primary spontaneous pneumothorax based primarily on the outcome of the post-aspiration chest radiograph which we have shown to be a poor predictor of early lung re-collapse. Using a simple bedside test in combination with the post-aspiration chest radiograph, we can predict with high accuracy the success of aspiration in achieving sustained lung re-inflation, thereby identifying patients with primary spontaneous pneumothorax who can be safely and immediately discharged home and those who should be observed overnight because of a significant risk of re-collapse, with an estimated re-admission rate of 1%.

Feasibility of early removal of chest tube in the operating room for spontaneous pneumothorax: A prospective randomized controlled study

Background/ObjectiveChest drainage tube after surgery causes pain and prolonged length of hospital stay. Especially, young patients tend to experience greater postoperative pain than elderly patients. Therefore, we needed to discuss the indication of chest tube placement. The purpose of this study was to demonstrate the safety and advantages of post-operative management without drainage tube placement, by comparing cases with and without drainage tube placement.MethodsPatients who underwent bullectomy for spontaneous pneumothorax were enrolled in this prospective randomized controlled study and randomized into two groups: group with a post-operative chest tube and group without a chest tube. Surgery and post-operative management were performed according to our protocol.ResultsAmong the 42 patients, pneumothorax occurred in 1 patient with a chest tube a day after tube removal. Patients without chest tube had significantly lower post-operative pain (P = 0.107～P < 0.001), despite their reduced use of rescue drugs. The mean length of post-operative hospital stay was 2.5 days in patients with chest tube, which was significantly longer than that of patients without chest tube (1.2 days; P < 0.001).ConclusionsOur patient selection and surgical protocols may be feasible and contribute to post-operative pain control.     

Medical and Surgical Management for Chronic Thromboembolic Pulmonary Hypertension: A Single Center Experience

IntroductionPulmonary endarterectomy (PE) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH). The aim of this study was to analyze our experience in the medical and surgical management of CTEPH.MethodsWe included 80 patients diagnosed with CTEPH between January 2000 and July 2012. Thirty-two patients underwent PE and 48 received medical treatment (MT). We analyzed functional class (FC), 6-min walking distance (6MWD), and pulmonary hemodynamics. Mortality in both groups and periods were analyzed.ResultsPatients who underwent PE were younger, mostly men, and had longer 6MWD. No differences were observed in pulmonary hemodynamics or FC at diagnosis. One year after treatment, all PE patients versus 41% in MT group were at FC I–II. At follow-up, the PE group showed greater increase in 6MWD, and greater reduction in mean pulmonary arterial pressure and pulmonary vascular resistance than the MT group (P<.05). Overall survival in the MT group at 1 and 5 years was 83% and 69%, respectively. Conditional survival in patients alive 100 days post-PE at 1 and 5 years was 95% and 88%, respectively. Surgical mortality in operated patients in the first period (2000–2006) was 31.3%, and 6.3% in the second (2007–2012).ConclusionsPE provides good clinical results, and improves pulmonary hemodynamics in patients who successfully overcome the immediate postoperative period. After a learning period, the current operatory mortality in our center is similar to international standards.     

Combined Transbronchial Needle Aspiration and 99mTc-2-Methoxy-Isobutyl-Isonitrile Single Photon Emission Computed Tomography for Diagnosing Enlarged Mediastinal Lymph Nodes

BackgroundTo demonstrate the diagnostic accuracy of an integrated approach of blind trans-bronchial needle aspiration (TBNA) and ^99mTc-2-methoxy-isobutyl-isonitrile single photon emission computed tomography (^99mTc-MIBI-SPECT) in diagnosing mediastinal lymph adenopathy.MethodsSixty-one consecutive patients with mediastinal lymph adenopathy undergoing both TBNA and ^99mTc-MIBI-SPECT were prospectively enrolled. Mediastinoscopy was attended in case of negative TBNA.ResultsEighty-three adenopathies were sampled (73 malignant and 10 benign). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TBNA was 74%, 100%, 100%, and 34%, respectively; and of ^99mTc-MIBI-SPECT were 96%, 80%, 97%, and 73%, respectively. Combining TBNA and ^99mTc-MIBI-SPECT results sensitivity, specificity, PPV, NPV of 97%, 100%, 100%, and 83%, respectively, were obtained. TBNA alone avoided mediastinoscopy in 65% of cases, while an integrated approach could have potentially obviated mediastinoscopy in 76%.Conclusions^99mTc-MIBI-SPECT improved the sensitivity and the NPV of TBNA, reducing the need of mediastinoscopy.     

Utility of Diagnostic Markers in Late Periprosthetic Joint Infection Workup for Total Knee Arthroplasty Patients Who Received Antibiotics 48 Hours Before Aspiration

BackgroundDiagnosing periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) remains challenging despite recent advancements in testing and evolving criteria over the last decade. Moreover, the effects of antibiotic use on diagnostic markers are not fully understood. Thus, this study sought to determine the influence of antibiotic use within 48 hours before knee aspiration on synovial and serum laboratory values for suspected late PJI.MethodsPatients who underwent a TKA and subsequent knee arthrocentesis for PJI workup at least 6 weeks after their index arthroplasty were reviewed across a single healthcare system from 2013 to 2020. Median synovial white blood cell (WBC) count, synovial polymorphonuclear (PMN) percentage, serum erythrocyte sedimentation rate (ESR), serum C-reactive protein (CRP), and serum WBC count were compared between immediate antibiotic and nonantibiotic PJI groups. Receiver operating characteristic (ROC) curves and Youden’s index were used to determine test performance and diagnostic cutoffs for the immediate antibiotics group.ResultsThe immediate antibiotics group had significantly more culture-negative PJIs than the no antibiotics group (38.1 versus 16.2%, P = .0124). Synovial WBC count demonstrated excellent discriminatory ability for late PJI in the immediate antibiotics group (area under curve, AUC = 0.97), followed by synovial PMN percentage (AUC = 0.88), serum CRP (AUC = 0.86), and serum ESR (AUC = 0.82).ConclusionAntibiotic use immediately preceding knee aspiration should not preclude the utility of synovial and serum lab values for the diagnosis of late PJI. Instead, these markers should be considered thoroughly during infection workup considering the high rate of culture-negative PJI in these patients.Level of EvidenceLevel III, retrospective comparative study.     

Pressure Ulcers and Prolonged Hospital Stay in Hip Fracture Patients Affected by Time-to-Surgery

Abstract Background: Hip fractures are associated with high morbidity. Pressure ulcer formation after hip surgery is often related to delayed patient mobilization. The objectives of this study were to determine whether time-to-surgery affects development of pressure ulcers postoperatively and, thus, length of hospital stay. Patients and Methods: We performed a retrospective analysis of consecutive hip fracture patients, aged 60 years and above, who underwent surgery between 1995 and 2001. The primary outcome was in-hospital development of pressure ulcers. The secondary outcome measure was the overall length of hospital stay. Analyses were adjusted for relevant confounders. Results: Of the 722 patients enrolled, 488 patients (68%) received surgery at 12 h after admission. Approximately 30% (n = 214) developed pressure ulcers during admission, whilst 19% of patients operated within 12 h of admission developed pressure ulcers. Time-to-surgery was an independent predictor of both development of pressure ulcers (OR = 1.7, 95% confidence interval [CI] = 1.2–2.6; p = 0.008) and length of hospital stay (11.3 vs 13.3 days in the early and the late surgery group, respectively, p = 0.050). Furthermore, development of pressure ulcers was associated with prolonged postoperative hospital stay (19.5 vs 11.1 days for patients with and without pressure ulcers, respectively, p = 0.001) Interpretation: In hip fracture patients, time-to-surgery was an independent predictor of both postoperative pressure ulcer development and prolonged hospital stay. These data suggest that the implementation of an early surgery protocol following admission for hip fractures may reduce both the postoperative complications and overall hospital stay. Investigation performed at the Department of Traumatology, Maastricht University Hospital, Maastricht, The Netherlands.     

Management of Prolonged Pulmonary Air Leaks With Endobronchial Valve Placement

Background:Prolonged pulmonary air leaks (PALs) are associated with increased morbidity and extended hospital stay. We sought to investigate the role of bronchoscopic placement of 1-way valves in treating this condition.Methods:We queried a prospectively maintained database of patients with PAL lasting more than 7 days at a tertiary medical center. Main outcome measures included duration of chest tube placement and hospital stay before and after valve deployment.Results:Sixteen patients were eligible to be enrolled from September 2012 through December 2014. One patient refused to give consent, and in 4 patients, the source of air leak could not be identified with bronchoscopic balloon occlusion. Eleven patients (9 men; mean age, 65 ± 15 years) underwent bronchoscopic valve deployment. Eight patients had postoperative PAL and 3 had a secondary spontaneous pneumothorax. The mean duration of air leak before valve deployment was 16 ± 12 days, and the mean number of implanted valves was 1.9 (median, 2). Mean duration of hospital stay before and after valve deployment was 18 and 9 days, respectively (P = .03). Patients who had more than a 50% decrease in air leak on digital monitoring had the thoracostomy tube removed within 3–6 days. There were no procedural complications related to deployment or removal of the valves.Conclusions:Bronchoscopic placement of 1-way valves is a safe procedure that could help manage patients with prolonged PAL. A prospective randomized trial with cost-efficiency analysis is necessary to better define the role of this bronchoscopic intervention and demonstrate its effect on air leak duration.

Hospital Management and Ambulatory Patient Care After COVID-19 Infection in Kidney Transplant

BackgroundA large number of registries have been collected for kidney transplant recipients infected with COVID-19.MethodsFrom March 2020 to April 2021, our team conducted an observational study, which included all patients who showed a polymerase chain reaction positive for COVID-19. Patients were divided into 2 groups: patients who required ambulatory care and patients who needed hospital admission.ResultsA total of 76 kidney transplant recipients were infected with COVID-19. A total of 33% required hospital admission and 65% received ambulatory treatment; 28% of our patients were asymptomatic and 6.8% died. Immunosuppressive treatment was modified in both study groups, and there were not any acute rejection episodes or changes in the human leukocyte antigen antibodies profile in our patients during our clinical trial.ConclusionsIn our study there was a significant percentage of patients who did not require hospital admission compared with other studies. In addition, we think that the reduction of immunosuppression can be a safe and reliable treatment.     

Valor pronóstico de la invasión de grasa perirrenal y/o del seno en pacientes con carcinoma de células renales pT3a: estudio de cohorte multicéntrico. Grupo LARCG

Introduction and objectivesThe objective of this study is to evaluate overall survival (OS), cancer-specific survival (CSS), relapse-free survival, local and distant (LRFS and DRFS, respectively) rates in patients with pT3a renal cell carcinoma (RCC) considering the perirenal and/or sinus fat infiltration (FI) as prognostic factors.Materials and methodsRetrospective cohort of patients with pT3a RCC who underwent radical or partial nephrectomy. The data were extracted from the LARCG (Latin American Renal Cancer Group) database. The demographic, clinical, pathological and surgical variables were evaluated. FI was divided into 4 groups (vein, perirenal, sinus and both fats infiltration). The Kaplan Meier and Cox regression curves were performed.Results293 patients were included in the study. The mean age was 61.4 years. The median follow-up was 21 months (r: 1-194). CSS, RFS, LRFS and DRFS estimated at 3 years in the group of both fats’ infiltration were 53.1, 45.1, 58.7 and 51.6 months, respectively, and always statistically lower than the rest (P?0.005). In the multivariate analysis, the infiltration of both fats significantly increased specific mortality, overall and local relapse with respect to vein infiltration (HR: 4.5, 2.42 and 8.08, respectively). The Fuhrman grade and renal pelvis infiltration were independent predictors of CSS and RFS.ConclusionsInfiltration of both fats increases the risk of overall and local relapse in pT3a RCC. In the same way, it is associated with a lower cancer-specific survival and should be considered as a factor of poor prognosis.     

Bariatric surgery and COVID-19 outcomes: a systematic review and meta-analysis

BackgroundObesity and its associated complications have a negative impact on human health. Metabolic and bariatric surgery (MBS) ameliorates a series of clinical manifestations associated with obesity. However, the overall efficacy of MBS on COVID-19 outcomes remains unclear.ObjectivesThe objective of this article is to analyze the relationship between MBS and COVID-19 outcomes.SettingA meta-analysis.MethodsThe PubMed, Embase, Web of Science, and Cochrane Library databases were searched to retrieve the related articles from inception to December 2022. All original articles reporting MBS-confirmed SARS-CoV-2 infection were included. Outcomes including hospital admission, mortality, intensive care unit (ICU) admission, mechanical ventilation utilization, hemodialysis during admission, and hospital stay were selected. Meta-analysis with fixed or random-effect models was used and reported in terms of odds ratios (ORs) or weighted mean differences (WMDs) along with their 95% confidence intervals (CIs). Heterogeneity was assessed with the I² test. Study quality was assessed using the Newcastle-Ottawa Scale.ResultsA total of 10 clinical trials involving the investigation of 150,848 patients undergoing MBS interventions were included. Patients who underwent MBS had a lower risk of hospital admission (OR: .47, 95% CI: .34–.66, I² = 0%), mortality (OR: .43, 95% CI: .28–.65, I² = 63.6%), ICU admission (OR: .41, 95% CI: .21–.77, I² = 0%), and mechanical ventilation (OR: .51, 95% CI: .35–.75, I² = 56.2%) than those who did not undergo surgery, but MBS did not affect hemodialysis risk or COVID-19 infection rate. In addition, the length of hospital stay for patients with COVID-19 after MBS was significantly reduced (WMD: −1.81, 95% CI: −3.11–.52, I² = 82.7%).ConclusionsOur findings indicate that MBS is shown to improve COVID-19 outcomes, including hospital admission, mortality, ICU admission, mechanical ventilation, and hospital stay. Patients with obesity who have undergone MBS infected with COVID-19 will have better clinical outcomes than those without MBS.     

Foot burns: A comparative analysis of diabetic and non-diabetic patients

IntroductionFoot burns represent a small part of the body with many challenges. The impact of diabetes on clinical outcomes adds further issues in management that clinicians must consider in their management. These factors have serious implications on morbidity and long term sequelae. Our aim is to analyse epidemiological trends of foot burns and examine the differences between diabetic and non-diabetics at Concord hospital from 2014 to 2019.MethodsA retrospective audit from 2014–19 at Concord General Repatriation Hospital Burns Unit summarised patient demographics, burn injury, diabetic status, operations and length of stay. All foot burn injuries from 2014–19 of all ages and gender that attended Concord burns hospital were included in this study.ResultsWe treated 797 patients who presented with foot burns, of which 16.2% were diabetic. The average age was higher in diabetics (60.72 years) than non-diabetics (39.72 years) and more males suffered burns compared to females in both groups (p < 0.001). There was a larger portion of elderly patients (greater than 65 years old, 15.1% of total) who sustained foot burns in the diabetic group compared to the non-diabetic group (p < 0.001). The most affected season was summer (27.0%), but diabetic patients were 1.7 times more likely to sustain injury in winter than non-diabetics. Diabetics were 3.8 times more likely to have contact burns compared to non-diabetic patients (p < 0.001). In a multivariable linear regression analysis, factors that contributed to increased length of stay included elderly status, place of event, diabetic status, number of operations, ICU admission, wound infection, amputation, and admission [F (16, 757 = 41.149, p < 0.001, R² = 0.465].ConclusionsWith the increase of diabetes, our multidisciplinary approach to diabetic foot care should include nursing, medical and surgical disciplines to identify patients at risk. The data highlights that a focus on prevention and education for diabetes is central to optimize glycaemic control and burn management, whilst providing a multidisciplinary network on discharge.     

The course of COVID-19 in patients with Behçet’s disease

ObjectivesTo evaluate the frequency and clinical course of coronavirus disease 2019 (COVID-19) in patients with Behçet’s disease (BD).Material and methodsThe study included patients diagnosed with BD according to the International Study Group for BD criteria who were being followed up in the Dermatology and Rheumatology clinics. Patients who applied to Rheumatology and Dermatology clinics and were not diagnosed with any rheumatological disease were taken as the control group. The medical records of the patients were examined retrospectively. A record was made of age, gender, additional systemic disease, for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), colchicine treatment dose, whether or not a polymerase chain reaction (PCR) test was performed, disease course in patients diagnosed with COVID-19, length of stay in hospital, and the need or not for intensive care unit (ICU) admission.ResultsEvaluation was made of 203 BD patients and a control group of 200 individuals. No difference was determined between the groups in respect of age and gender (respectively p = 0.348, p = 0.828). A polymerase chain reaction test for the SARS-CoV-2 was applied to 56 patients in the BD group, and 18 were reported positive, and to 80 subjects in the control group, of which 32 were determined positive. No difference was determined between the groups in terms of PCR test positivity (p = 0.321). No significant difference was determined between the groups in length of stay in hospital, lung involvement, ICU admissions, and mortality rates (respectively p = 0.684, p = 1.000, p = 0.503, p = 1.000). In the BD patient group, in all the parameters there was no significant difference between those who were positive or negative for COVID-19.ConclusionsThe results of this study showed no increased risk for BD patients compared to the normal population in respect of the frequency of SARS-CoV-2 infection, length of hospital stay, lung involvement, ICU admission and mortality.     

Re-admissions for delayed complications after cytoreductive surgery and HIPEC

Background: Peritoneal metastasis (PM) is currently treated with the complex procedure of cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS?+?HIPEC). This procedure presents high morbidity and mortality rates, but they have only been examined in the immediate post-operative period. The aim of our study is to present, describe and analyze the post-operative events, secondary to a cytoreductive surgery and HIPEC procedure that occurs after the patients’ discharge from the hospital. Patients and methods: We examine retrospectively 219 patients who were discharged from our hospital from the initial 230 patients with PM, who were operated on from August 2005 to August 2015 and underwent CRS and HIPEC. Complications are investigated from the patient’s discharge date until the 90th post-operative day, and are categorized with the Clavien-Dindo classification. Results: We identified 17 patients (7.8%) who developed late complications. No major differences in patient characteristics were identified between this group of 17 patients and the rest, apart from a slightly higher PCI (23.5 vs. 22.3). Mean length of stay at the re-admission was 11.7 days. 5 of the patients (29.4%) had to be re-operated on, whereas we found a mortality of 11.8% (2/17 patients). The most common complications involved abdominal abscesses (17.6%), ureteral strictures (17.6%) and enterocutaneous fistulae (17.6%). Conclusion: Our study highlights the late complications following CRS plus HIPEC procedures, that occur after the patient’s discharge from the hospital, an issue that has not been investigated thoroughly yet and may have serious impact on the post-operative quality of life. The role of adjuvant chemotherapy following CRS and HIPEC procedures in the onset of such complications appears to be important and needs further investigation.     

Chest Injuries in Polytrauma

Abstract Background and Purpose: Blunt chest injuries are commonly seen in polytrauma patients and are known to be associated with higher mortality and morbidity. The objectives of the present study are to assess the effect of blunt chest injury concerning morbidity, mortality as well as clinical courses and outcome of multiply injured patients with chest trauma. Patients and Methods: This study includes all polytrauma patients with chest injury treated between 1992 and 2002 at a major urban trauma center. Parameters examined included injury pattern, injury severity, mortality, hemodynamics at admission, duration of ventilation, length of stay in intensive care unit (ICU), and outcome. Results: 332 out of 501 polytrauma patients, 228 males and 104 females, had a coexisting chest injury. Mean age at the time of injury was 37.7 years, and 258 patients were intubated before admission. Average period on ICU was 15.4 days, and 35.9 days for total hospital stay. Regarding the injury pattern in 143 patients a combined hemo-/pneumothorax was seen, 109 patients had either a hemothorax or a pneumothorax, in 155 patients a unilateral and in 52 patients a bilateral serial rib fracture was diagnosed, in 28 patients either sternal or singular rib fractures were determined, in a total of 23 patients an unstable thorax or a flail chest was seen, 105 patients had a unilateral pulmonary contusion, and in 79 patients a bilateral pulmonary contusion was diagnosed. Finally, a total of eleven patients with a traumatic aortic disruption were identified. Conclusion: The present study shows that chest injuries in polytrauma patients are common coexisting injuries and contribute significantly to the morbidity and outcome of these patients. Early intubation and ventilation in combination with an adequate circulatory stabilization are crucial to avoid complications and deleterious outcome.     

Evolution of the Use of Noninvasive Mechanical Ventilation in Chronic Obstructive Pulmonary Disease in a Spanish Region, 1997–2010

IntroductionNoninvasive mechanical ventilation (NIV) appeared in the 1980s as an alternative to invasive mechanical ventilation (IMV) in patients with acute respiratory failure. We evaluated the introduction of NIV and the results in patients with acute exacerbation of chronic obstructive pulmonary disease in the Region of Murcia (Spain).Subjects and methodsA retrospective observational study based on the minimum basic hospital discharge data of all patients hospitalised for this pathology in all public hospitals in the region between 1997 and 2010. We performed a time trend analysis on hospital attendance, the use of each ventilatory intervention and hospital mortality through JoinPoint regression.ResultsWe identified 30 027 hospital discharges. JoinPoint analysis: downward trend in attendance (annual percentage change [APC]=?3.4, 95% CI: ?4.8 to ?2.0, P<.05) and in the group without ventilatory intervention (APC=?4.2%, ?5.6 to ?2.8, P<.05); upward trend in the use of NIV (APC=16.4, 12.0–20.9, P<.05), and downward trend that was not statistically significant in IMV (APC=?4.5%, ?10.3 to 1.7). We observed an upward trend without statistical significance in overall mortality (APC=0.5, ?1.3 to 2.4) and in the group without intervention (APC=0.1, ?1.6 to 1.9); downward trend with statistical significance in the NIV group (APC=?7.1, ?11.7 to ?2.2, P<.05) and not statistically significant in the IMV group (APC=?0.8, ?6, 1–4.8). The mean stay did not change substantially.ConclusionsThe introduction of NIV has reduced the group of patients not receiving assisted ventilation. No improvement in results was found in terms of mortality or length of stay.     

Intraoperative intercostal nerve cryoablation During the Nuss procedure reduces length of stay and opioid requirement: A randomized clinical trial

PurposeMinimally-invasive repair of pectus excavatum by the Nuss procedure is associated with significant postoperative pain, prolonged hospital stay, and high opiate requirement. We hypothesized that intercostal nerve cryoablation during the Nuss procedure reduces hospital length of stay (LOS) compared to thoracic epidural analgesia.DesignThis randomized clinical trial evaluated 20 consecutive patients undergoing the Nuss procedure for pectus excavatum between May 2016 and March 2018. Patients were randomized evenly via closed-envelope method to receive either cryoanalgesia or thoracic epidural analgesia. Patients and physicians were blinded to study arm until immediately preoperatively.SettingSingle institution, UCSF-Benioff Children's Hospital.Participants20 consecutive patients were recruited from those scheduled for the Nuss procedure. Exclusion criteria were age < 13 years, chest wall anomaly other than pectus excavatum, previous repair or other thoracic surgery, and chronic use of pain medications.Main outcomes and measuresPrimary outcome was postoperative LOS. Secondary outcomes included total operative time, total/daily opioid requirement, inpatient/outpatient pain score, and complications. Primary outcome data were analyzed by the Mann–Whitney U-test for nonparametric continuous variables. Other continuous variables were analyzed by two-tailed t-test, while categorical data were compared via Chi-squared test, with alpha = 0.05 for significance.Results20 patients were randomized to receive either cryoablation (n = 10) or thoracic epidural (n = 10). Mean operating room time was 46.5 min longer in the cryoanalgesia group (p = 0.0001). Median LOS decreased by 2 days in patients undergoing cryoablation, to 3 days from 5 days (Mann–Whitney U, p = 0.0001). Cryoablation patients required significantly less inpatient opioid analgesia with a mean decrease of 416 mg oral morphine equivalent per patient (p = 0.0001), requiring 52%–82% fewer milligrams on postoperative days 1–3 (p < 0.01 each day). There was no difference in mean pain score between the groups at any point postoperatively, up to one year, and no increased incidence of neuropathic pain in the cryoablation group. No complications were noted in the cryoablation group; among patients with epidurals, one patient experienced a symptomatic pneumothorax and another had urinary retention.Conclusions and relevanceIntercostal nerve cryoablation during the Nuss procedure decreases hospital length of stay and opiate requirement versus thoracic epidural analgesia, while offering equivalent pain control.Type of studyTreatment study.Level of evidenceLevel I.
