Selective Management of Multiple Anterior Abdominal Stab Wounds: Is it Safe?

BACKGROUND: Selective management of stable patients with anterior abdomen stab wounds (AASWs) has become a gold standard management approach throughout the world. Evidenced-based options for supporting selective management include clinical follow-up, local wound exploration with or without diagnostic peritoneal lavage, diagnostic laparoscopy, and abdominal computerized tomography. The presence of multiple AASWs might signify a more aggressive attack and limit the safety of a selective management approach. OBJECTIVES: To evaluate whether multiple AASWs are associated with an increased risk of intra-abdominal injury requiring emergency surgery. METHODS: We retrospectively reviewed all AASW patients admitted to Assaf Harofeh Medical Center, Zerifin, Israel, and Hillel Yaffe Medical Center in Hadera, Israel, from 2007 to 2015. Patients were divided into two groups based on the number of stab wounds: single or multiple. Data were coded for demographics, severity of injury, presence of intra-abdominal injury, laparotomy rate, length of hospital stay (LOS), length of stay in the intensive care unit (LICU), and survival. RESULTS: The study included 169 patients. Of these, 143 patients had a single AASW and 26 had multiple AASWs. There were no differences between the groups regarding demographics, severity of injury, intra-abdominal penetration, specific organ injury, LOS, or LICU. There was no difference in the percentage of patients requiring laparotomy. The overall mortality was 2.36% (4/169). There was no significant difference in the mortality rate between the groups (P = 0.11). CONCLUSIONS: The presence of multiple AASWs is not a risk factor for increased frequency and severity of intra-abdominal injury.

[HIGH VOLTAGE ELECTRIC INJURY: MECHANISM OF INJURY, CLINICAL FEATURES AND INITIAL EVALUATION.]

INTRODUCTION: Electrical injury is an infrequent but potentially devastating form of multisystem injury associated with high morbidity and mortality. Despite significant improvement in injury prevention and implementation of safety protocols at work places, electrical injury accounts for more than 500 deaths per year in the United States with a mortality rate of 10-30%. Electrical injuries are traditionally divided into low-voltage electric power injuries (less than 1,000V) and high-voltage )more than 1,000V). In contrast with other types of trauma, high voltage injuries present some rather unique problems that require a high index of suspicion and awareness of all possible manifestations. Electrical injury should be viewed and managed as a multisystem injury, since there is virtually no organ that is protected against it. The most essential concept of successful management of patients who sustain high voltage injury is that there is no relationship between skin burn, vital organs involvement and severity of injuries. This review aims to provide a comprehensive overview of reported high voltage electrical injury manifestations in an attempt to gain a better understanding of the distribution of morbidity and clinical features of the injury. We tried to encompass most of the reported cases of high voltage electrical injuries in order to give the readers a general view of the spectrum of injuries that can be encountered in victims suffering high voltage current, aiming to increase the awareness of emergency care and trauma teams to this rare but dangerous and potentially fatal type of injury.
