Degloving injuries of the abdominal wall l Objective: To stress the local, regional and global impact of degloving injuries of abdominal wall based on which the surgeon can design the management protocol. l Method: A retrospective series of seven cases who met with high velocity run-over accidents between the year 2002 to 2007. All patients were clinically examined and the findings confirmed radiologically, which guided the management. l Results: Out of the seven patients treated, six survived. All patients had open degloving injury of abdominal wall and in different areas of the lower limbs, while three had an additional closed degloving in the back, thighs and gluteal regions. All of them had pelvic fractures of various types.Three patients had peritoneal injury, of whom one had additional diaphragmatic injury. None of them had hollow viscus perforation or injury to solid viscera despite the varied severity of injuries to the abdominal wall, pelvic bone and diaphragm. l Conclusion: Degloving injuries of the abdominal wall are rarely encountered in our practice. The associated morbidity and mortality are very high. However, the prognosis can be improved by successful revival and rehabilitation of these patients, which is possible by early resuscitation, recognition of all bony and soft tissue injuries, early debridement and coverage. l Declaration of interest: There were no external sources of funding for this study. The authors have no conflicts of interest to declare with regard to the manuscript or its content.

on the basis of which the surgeon can design the management protocol. The extent of degloving, friction injuries, skin loss, different types of associated pelvic fractures and other injuries are emphasised. The concerns, current approaches and their limitations in our patients are also highlighted.

Method All patients in our series presented to the accident and emergency department (A&E) of our hospital, a tertiary centre, during 2002–2007 with degloving injuries of the abdominal wall following high-velocity road traffic accidents. All patients were clinically assessed on arrival to the hospital. Bony injuries were confirmed by radiological examination. Computed tomography (CT) scans were performed only in patients who had peritoneal injury seen through the open abdominal wound, in order to assess the intra-abdominal organs. Pre-operative urethrogram was performed in patients with pelvic fracture and suspected urethral injury.

Management Patients were assessed by a multidisciplinary team of intensivists, orthopaedic surgeons, general surgeons, plastic surgeons and urologists at the A&E. They were initially resuscitated and then clinically examined to assess the nature and extent of injuries. Clinical findings were confirmed by radiological investigations. CT scans of the abdomen was done

egloving injuries of the anterior abdominal wall are quite rare compared with those of extremities or scalp, as the mechanism and forces acting are different. In the extremities, bone provides a solid counteractive force, whereas in the abdominal wall, degloving occurs against the musculo-aponeurotic layer, which is a tough structure comparable to bone.1 The severity of degloving is proportional to magnitude of external force. These injuries are generally described as: l Open or anatomical degloving injury  When a tangential external force of sufficient magnitude is applied to the body surface, a sudden shearing tears the skin and subcutaneous tissues away from the underlying solid skeletal structures. The separation of tissue planes injures blood vessels, resulting in compromised circulation to the overlying tissues.2 l  Closed or physiological degloving  This is also known as a Morel-Lavallée lesion, which is the result of traumatic shearing of skin and subcutaneous tissues from deep fascia, without any open wound.3 This may present as abnormally loose skin, as it lacks normal connections to underlying tissues. The overlying skin may sometimes also be bruised. It leaves a large dead space with haematoma.4 Here, we present a series of patients with degloving injuries of the abdominal wall. The aim of this paper is to stress the local, regional and global impact of degloving injuries of the abdominal wall,

practice in patients with clinically obvious peritoneal tear and suspicion of diaphragmatic injury, when gurgling sounds were heard on auscultation of chest. Pneumothorax and haemothorax were assessed by chest X-ray, CT and ultrasound scans. Patients received tetanus prophylaxis and antibiotics were administered according to hospital antibiotic policy: 12-hourly intravenous (IV) ceftriaxone 1g and 8-hourly metronidazole in A&E, and 12-hourly amikacin 500mg after the creatinine reports were available. Antibiotics were changed later, according to culture and sensitivity reports correlated with clinical response. Morphine 0.1mg/kg body weight was administered for pain relief, after preliminary examination. Global haemodynamics were assessed by hourly urine output, heart rate, blood pressure, central venous pressure monitoring, haemoglobin and packed-cell volume. Blood components and IV fluids were administered accordingly. Electrolyte losses were assessed by serial laboratory estimations of serum sodium, potassium, chloride, calcium, arterial blood gases and necessary corrections made. Sepsis was assessed by monitoring temperature, respiratory rate, heart rate, blood pressure, central venous pressure, reduced bowel sounds and urine output. Laboratory parameters, such as total leukocyte count, platelet count, serum electrolytes, arterial blood gases, liver function test and chest X-ray were serially conducted as per intensive care unit (ICU) protocol. Serial wound, blood and urine cultures were done to guide antibiotic therapy.

Primary surgical procedures in the form of stabilisation of pelvic and long bone fractures, and wound debridement were carried out. Exploratory laparotomy was performed in patients with peritoneal tear. The adequacy of debridement and tissue viability was assessed based on the colour of tissues and bleeding from incised edges of dermis, as it is the key to flap survival. Closed degloving injuries were managed by evacuation of haematoma, by making incision in the degloved part, lavage and placement of suction drains. The site of incision for draining the haematoma was chosen carefully by avoiding the possible future flap territories. Peritoneal and muscle defects were repaired directly, whereas larger abdominal muscle defects were reconstructed with flaps. Abdominal wound resurfacing was done with split-thickness skin grafts (STSGs). Following surgery, pain was assessed by a visual analog scale (VAS) and managed as per the following protocol: l 6-hourly morphine 4mg injection in adults (0.05mg/kg in children) during the postoperative period following repeated surgeries, and on request if VAS > 6 while in the ICU j o u r n a l o f wo u n d c a r e v o l 2 2 , n o 1 0 , O c to b e r 2 0 1 3
