RESUMEN
BACKGROUND: No guidelines exist for the evaluation of patients after near hanging. Most patients receive a comprehensive workup, regardless of examination. We hypothesize that patients with a normal neurologic examination, without major signs or symptoms suggestive of injury, require no additional workup. METHODS: We reviewed medical charts of adult trauma patients who presented to a Level I trauma center between 1995 and 2013 after an isolated near-hanging episode. Demographics, Glasgow Coma Scale (GCS) score, imaging, and management were collected. Patients were stratified by neurologic examination into normal (GCS score = 15) and abnormal (GCS score <15) groups. Comparison between the groups was completed using univariate analyses. RESULTS: One hundred twenty-five patients presented after near hanging: 42 (33.6%) had abnormal GCS score, and 83 (66.4%) were normal. Among the normal patients, seven patients (8.5%) reported cervical spine tenderness; these patients also had abnormal examination findings including dysphagia, dysphonia, stridor, or crepitus. The normal group underwent 133 computed tomography scans and seven magnetic resonance imaging scans, with only two injuries identified: C5 facet fracture and a low-grade vertebral artery dissection. Neither injury required intervention. In patients with normal GCS score, cervical spine tenderness and at least one significant examination finding were 100% sensitive and 79% specific for identifying an underlying injury. CONCLUSION: Patient with normal GCS score, without signs and symptoms of injury, are unnecessarily receiving extensive diagnostic imaging. Imaging should be reserved for patients with cervical spine tenderness and dysphagia, dysphonia, stridor, and/or crepitus without the fear of incomplete workup. All patients with signs of additional trauma or decreased GCS score should be studied based on preexisting protocols. LEVEL OF EVIDENCE: Therapeutic/care management study, level V.

BACKGROUND: Ventilator-associated pneumonia is a problem in trauma and emergency general surgery patients. Our hospital-acquired infection prevention committee approved the use of early nonbronchoscopic bronchoalveolar lavage (screening-BAL) in the surgical intensive care unit (SICU) to identify ventilated patients with bronchiolar bacteria before 48 hours. We reviewed the results of this quality improvement initiative. METHODS: All ventilated patients in the SICU (March 2011 to June 2012) underwent a screening-BAL 36 hours to 48 hours after intubation; quantitative culture results (>5 × 10(4) colony-forming unit per milliliter) were used to identify positive specimens. Clinical pneumonia was defined as clinical pulmonary infection score greater than 6 with a subsequent positive diagnostic-BAL result. Sequential organ failure assessment scores were averaged for the first 48 hours in the SICU. Continuous and dichotomous data were compared, and a multivariate regression analysis was performed on the screening-BAL and pneumonia results. RESULTS: Screening-BALs were performed in 150 patients (99 trauma and 51 emergency general surgery patients), 72 of these specimens had positive findings. Fifty-three clinical pneumonias were diagnosed, and 45 (positive predictive value, 0.85) identified the same organism as the screening-BAL. Clinical pneumonia developed in eight patients with a negative screening-BAL (negative predictive value, 0.85). Antibiotic therapy at the time of the screening-BAL was associated with a negative screen (odds ratio, 0.44; p = 0.026). Pneumonia developed on median postintubation Day 4 (2-15 days) in patients with a positive screening-BAL results as compared with day 7.5 in the patients with a negative screening-BAL results (3.5-15 days; p = 0.007). Field intubation is an independent risk factor (odds ratio, 3.5; p = 0.004). CONCLUSION: Positive screening-BAL results in trauma and emergency general surgery patients are associated with the development of ventilator-associated pneumonia by the same organism and may play a role in identifying patients at risk for pneumonia. Further studies must be conducted to evaluate the role of screening-BAL in this patient population. LEVEL OF EVIDENCE: Diagnostic/prognostic study, level III.

Historically, all splenic injuries were treated with splenectomy. In recent decades, however, there has been a trend toward splenic conservation methods in an attempt to preserve immunologic functions. Although cases of splenic conservation in the setting of penetrating injuries exist in the literature, this method of management is more commonly attempted in blunt traumas. When presented with penetrating splenic trauma, surgeons generally still proceed directly to exploratory laparotomy with splenectomy. Splenic injuries are rarely repaired with splenorrhaphy due to surgeon inexperience and concern for reoperation. We conclude from this case that when presented with a penetrating splenic trauma in a hemodynamically stable patient, management by laparoscopic exploration with splenorrhaphy can be safe and effective.
