A systematic review of combined pelvic and acetabular injuries

PurposeInjuries of both pelvic ring and acetabulum as rare very few articles are available in literature. There are no set protocols in defining the injury let alone defining early and definitive management strategies. This article is an attempt to encompass all available data to give us guidelines in managing these injuries.MethodsAn extensive literature review was carried out on PubMed/Medline, google scholar and Embase databases was done with the eligibility criteria of 1) Case series with a minimum of 20 cases. 2) The patient’s outcome reported. 3) Full article available. 4) Article in English. 5) Minimum Jadad score of 3. As per PRISMA guidelines the search was done and gradually filtered down to relevant articles which were 8 in number.ResultsThe incidence of these injuries range from 5 to 16%. The transverse acetabular fracture pattern is the commonest followed by associated both column fractures. There is equal propensity of Anteroposterior compression and lateral compression injuries. The injury mechanism appears to transmitted lateral force from the greater trochanter inwards with an implosion injury causing acetabular and pelvic injury as a continuum. The initial management is similar to managing pelvic ring injuries with focus on patient resuscitation, hemodynamic stabilization and temporary stabilization. The injury severity score and the mortality rates are comparable to isolated unstable pelvic ring injuries. Definitive management focuses on fixing the posterior pelvic ring first followed by the acetabular fracture and then the anterior pelvic ring. The displacement rates and outcome is worse than isolated acetabular injuries or pelvic injuries.ConclusionCombined Pelvic and acetabular injuries are complex injuries which need to be managed initially as we manage pelvic injury and later as we fix as an acetabular fracture meticulously.     

Stage 1 acute kidney injury is independently associated with infection following cardiac surgery

ObjectivesSevere acute kidney injury (AKI) is a known risk factor for infection and mortality. However, whether stage 1 AKI is a risk factor for infection has not been evaluated in adults. We hypothesized that stage 1 AKI following cardiac surgery would independently associate with infection and mortality.MethodsIn this retrospective propensity score–matched study, we evaluated 1620 adult patients who underwent nonemergent cardiac surgery at the University of Colorado Hospital from 2011 to 2017. Patients who developed stage 1 AKI by Kidney Disease Improving Global Outcomes creatinine criteria within 72 hours of surgery were matched to patients who did not develop AKI. The primary outcome was an infection, defined as a new surgical-site infection, positive blood or urine culture, or development of pneumonia. Secondary outcomes included in-hospital mortality, stroke, and intensive care unit (ICU) and hospital length of stay (LOS).ResultsStage 1 AKI occurred in 293 patients (18.3%). Infection occurred in 20.9% of patients with stage 1 AKI compared with 8.1% in the no-AKI group (P < .001). In propensity-score matched analysis, stage 1 AKI independently associated with increased infection (odds ratio [OR]; 2.24, 95% confidence interval [CI], 1.37-3.17), ICU LOS (OR, 2.38; 95% CI, 1.71–3.31), and hospital LOS (OR, 1.30; 95% CI, 1.17-1.45).ConclusionsStage 1 AKI is independently associated with postoperative infection, ICU LOS, and hospital LOS. Treatment strategies focused on prevention, early recognition, and optimal medical management of AKI may decrease significant postoperative morbidity.     

A 4‐year follow‐up case of extrusive luxation in a patient with cerebral palsy

Cerebral palsy (CP) is a condition caused by brain damage before, during, or shortly after birth. Communication can be a challenge when treating patients with CP. Some patients can communicate verbally, while others use augmentative alternative communication tools or have individualized means of communication. Therefore, professional dental treatment in individuals with CP is challenging, especially if the patient is affected by dental trauma and requires emergency treatment. This report shows how individualized communication skills assessment allowed us to successfully manage a 9‐year‐old patient with CP, who suffered extrusive luxation of the permanent lower incisor. In the present case, the teeth were repositioned briefly after the trauma had occurred and then stabilized with a flexible splint according to international guidelines. The teeth remained vital and periodontal repair was observed during the 4‐year follow‐up.     

Utility of INR For Prediction of Delayed Intracranial Hemorrhage Among Warfarin Users with Head Injury

BackgroundIncidence of delayed intracranial hemorrhage (DICH) in patients on warfarin has been controversial. No previous literature has reported the utility of international normalized ratio (INR) in predicting traumatic DICH.ObjectivesUtilizing INR to risk stratify head trauma patients who may be managed without repeat imaging.MethodsThis was a retrospective study at a Level II trauma center. All patients on warfarin with head injuries from March 2014 to December 31, 2017 were included. Each patient underwent an initial head computed tomography scan (HCT) and subsequent repeat HCT 12 h after. Patients presenting > 12 h after head injury received only one HCT. Two blinded neuroradiologists reviewed each case of DICH. Statistical analysis evaluated Glasgow Coma Scale (GCS), Injury Severity Score (ISS), heart rate, systolic blood pressure (SBP), age, and platelet count.ResultsThere were 395 patients who qualified for the protocol; 238 were female. Average age was 79 years. Seventy-seven percent of patients underwent repeat HCT. Five resulted in DICH (INR 2.6–3.0), three of which might have been present on initial HCT; incidence rate of 0.51–1.27%. One patient required neurosurgical intervention. Among 80 patients with INR < 2, no DICH was identified, resulting in high sensitivity, but with a wide confidence interval; sensitivity of 100% (95% confidence interval [CI] 47.8–100), specificity 21% (95% CI 16.6–28.9). Correlation of factors: ISS (p = 0.039), GCS (p = 0.978), HR (p = 0.601), SBP (p = 0.198), age (p = 0.014), and platelets (p = 0.281).ConclusionNo patient with INR < 2 suffered DICH, suggesting that warfarin users presenting with INR < 2 may be managed without repeat HCT. For INR > 2, patients age and injury severity can be used for shared decision-making to discharge home with standard head injury precautions and no repeat HCT.     

机械通气在胸部开放伤后海水灌入胸腔致急性肺损伤救治中的应用

目的探讨机械通气在胸部开放伤后海水灌入胸腔致急性肺损伤（ALI）救治中的应用。方法锐器致胸部开放伤后胸腔内灌注海水（35ml／kg）制备ALI成年杂交犬动物模型，随机分为未救治组、普通救治组、机械通气组，每组6只。未救治组在ALI出现后不实施任何救治措施，普通救治组给以鼻导管吸氧、胸腔闭式引流、静脉输入5％葡萄糖液等，机械通气组将普通救治组鼻导管吸氧改为机械通气。动态观察血气分析、血流动力学变化，检测外周血中炎症介质的变化。结果胸部开放伤后海水灌入胸腔可导致ALI，普通救治组PaO2虽有所升高但仍显著低于正常，机械通气能快速纠正低氧血症，两组在纠正高渗、高钠、高氯血症和改善血流动力学方面无显著差异。结论胸部开放伤后海水灌入胸腔引起严重ALI，机械通气具有良好的治疗效果。     

浮肩损伤的临床特征和治疗

目的 总结浮肩损伤（floating shoulder injury，FSI）的临床特征和治疗效果。方法1993年1月-2004年9月收治浮肩损伤患者8例，除2例行锁骨固定带固定外，其余6例均行手术治疗，其中单纯行锁骨切开复位重建钢板内固定1例，同时行肩胛骨内固定5例。受伤至手术时间为2h～7d，平均3．5d，术后6个月对患肩功能进行Constant评分判定疗效，并对浮肩损伤的临床特征和治疗进行总结。结果6例患者经过6个月～3年（平均11个月）的随访，锁骨和肩胛骨骨折均愈合，肩关节活动范围无明显受限，但有2例患者在举重物时肩关节有轻度的疼痛，1例患侧上肢肌力较对侧稍减弱。术后6个月患肩功能Constant评分平均为93分。结论浮肩损伤多为高能量暴力所致的不稳定性肩胛带损伤，在治疗方案上尚存争议。但对移位明显的浮肩损伤以及有伴发伤的浮肩损伤进行手术治疗是必要的。
