The incidence of obesity has been increasing in the United States, and the medical care of obese patients after injury is complex. Obesity has been linked to increased morbidity after blunt trauma. Whether increased girth protects abdominal organs from penetrating injury or complicates management from obesity-associated medical comorbidities after penetrating injury has not been well defined. All patients admitted with penetrating injury between January 1, 2010, and December 31, 2013, at a university-affiliated Level I center trauma center were reviewed. Primary endpoints for analysis were the presence of significant injuries requiring operative intervention and outcomes, including inpatient complications. Logistic regression, chi-squared tests, and the Kruskal-Wallis test were used to compare groups. Five hundred patients were included in the study; 225 with stabs and 275 with gunshot wounds (GSWs). In each group, there was no major difference between obese and nonobese patients in regard to injury location, operative approach, or postoperative outcomes. Unadjusted odds ratios comparing both overweight and obese individuals to normal BMI patients did not suggest a decreased rate of therapeutic operations for either population after stabs or GSWs. In obese or overweight patients, there is no difference in the rate of operative intervention for significant injuries after penetrating axial trauma compared with a normal BMI population. On the other hand, obesity was not associated with prolonged length of stay, increased complications, or death after penetrating injuries.

Damage control surgery involves an abbreviated operation followed by resuscitation with planned re-exploration. Damage control techniques can be used in thoracic trauma but has been infrequently reported. Our goal is to describe our experience with the use of damage control techniques in treating thoracic trauma. A retrospective analysis of all patients undergoing damage control thoracic surgery related to trauma from January 1, 2010, to January 1, 2013, at University of Louisville Hospital, a Level I trauma center. Variables studied included injury characteristics, Injury Severity Score, surgery performed, duration of packing, length of stay (LOS), ventilator days, transfusion requirements, complications, and mortality. Twenty-five patients underwent damage control surgery in the chest with packing, temporary closure, and planned re-exploration after stabilization. Seventeen patients underwent anterolateral thoracotomy, and eight patients underwent sternotomy. The mean LOS and duration of temporary packing was 20.6 and 1.4 days in the thoracotomy group, respectively, and 19.5 and 1 day in the sternotomy group, respectively. The overall mortality rate was 40 per cent, 35 per cent in the thoracotomy group and 50 per cent in the sternotomy group. Like in severe abdominal trauma, damage control techniques can be used in the management of severe thoracic injuries with acceptable results.
