Changing profiles in spinal cord injuries and risk factors influencing recovery after penetrating injuries.

OBJECTIVE The changing profiles of spinal cord injuries in South Africa are addressed in this study. DESIGN A retrospective analysis of 551 patients with spinal cord injury. MATERIALS AND METHODS The cause of injury was motor vehicle crashes in 30%, stab wounds in 26%, gunshot wounds in 35%, and miscellaneous causes 9%. MEASUREMENTS AND MAIN RESULTS There was a significant shift from stab wounds towards bullet wounds over the last five years. Bullet spinal cord injuries increased from 30 cases in 1988 to 55 cases in 1992, while stab spinal cord injuries decreased from 39 cases in 1988 to 20 cases in 1992. The incidence of spinal cord injuries following a motor vehicle crash showed a declining tendency after a transient increase (28 cases in 1988, 40 in 1990, 31 in 1992). Moreover, the problem of severe septic complications has been investigated and various risk factors for sepsis that might impair the rehabilitation process have been examined. The risk of developing septic complications was higher in gunshot spine injuries (21 cases out of 193) than in knife injuries (5 cases out of 143). The presence of a retained bullet did not seem to increase the chances for sepsis. In seven patients the sepsis was the direct consequence of the retained bullet while in 14 patients sepsis developed with no bullet in situ. Furthermore, the site of the injury (cervical, thoracic, lumbar spine) did not correlate with the abovementioned risks. CONCLUSIONS Gunshots carry a heavier prognosis. Only 32% of our gunshot cases underwent a significant recovery as opposed to 61% of stab cases and 44% of the motor vehicle crash victims.

Selective surgical management of zone II gunshot injuries of the neck : A prospective study

BACKGROUND The management of penetrating neck trauma remains controversial, with many studies supporting either mandatory exploration or selective conservatism. METHODS AND RESULTS This is a prospective study of 75 patients with gunshot injuries to zone II of the neck. Forty patients (53.3%) underwent immediate exploration because of clinical indications or positive initial investigations. A 7.5% incidence of unnecessary explorations, a 5% mortality rate, and average hospital stay of 10.5 days were noted. Thirty-five patients with negative clinical or investigational findings underwent observation with constant monitoring. A 5.7% incidence of missed injuries, no mortality, and an average hospital stay of 3.5 days were noted for these patients. CONCLUSIONS We suggest that conservative management in gunshot injuries confined to zone II of the neck selectively supplemented by appropriate investigations is a viable proposition in this type of injury. Further contemporary studies reporting specifically on this injury will enable us to reach statistically significant conclusions.

Extraperitoneal rectal gunshot injuries

Extraperitoneal rectal gunshot injuries are rare, but may be encountered in civilian practice. We report on a series of 26 such cases. The aim of the study is to attempt to evolve a treatment policy of this injury. The principles of management include the repair of rectal wound in selected cases and the formation of a diverting colostomy. Distal rectal washout and presacral drainage, although advocated by some authors, do not seem to be indispensable adjuncts to the management of these injuries.

Early Management of Gunshot Injuries to the Face in Civilian Practice

BackgroundGunshot injuries to the face in civilian practice are rarely reported. Potential complications in the Emergency Department can have catastrophic consequences, and inappropriate operative management of the facial soft and skeletal tissues are related to outcome.MethodsA structured diagnostic and management approach is used in our Trauma Unit to deal with gunshot wounds to the face. A retrospective study of 55 patients who sustained gunshot injury to the face was conducted over a 6½-year period. Demographic details, mechanism of injury, and mode of presentation and management were recorded. Mortality and morbidity data were collated.ResultsThere were 51 male and 4 female patients. All injuries were caused by low-velocity gunshots, except for one that was a shotgun injury. Overall, 28 of the 55 patients (50%) underwent orotracheal intubation on scene or in the resuscitation room, and 2 had cricothyroidotomy. In addition to the maxillofacial trauma, associated injuries were common. Forty patients underwent operation for maxillofacial trauma, 34 on the day of admission and the remaining 6 within 5 days of injury. Multiple operations over a 2-week period were necessary for 18 of the 40 patients. Complications directly related to the gunshot injury to the face were very limited. Mortality was related to associated injuries.ConclusionsGunshot injury to the face in civilian violence is a “benign” condition as long as the Patient’s airway is kept patent and hemorrhage is controlled. Early operative intervention for repair of the soft and skeletal facial structures leads to satisfactory results. Mortality directly related to the facial trauma is uncommon.

Trauma care systems in South Africa

AIM To provide an overview of the provision of trauma care in South Africa, a middle income country emerging into a democratic state. METHODS Literature review. CONCLUSIONS South Africa is gripped by an almost hidden epidemic of intentional and non-intentional injury, largely driven by alcohol and substance abuse, against a background of poverty and rapid urbanisation. Gross inequities exist in the provision of trauma care. Access to pre-hospital care and overloading of tertiary facilities are the major inefficiencies to be addressed. The burden of disease due to trauma presents unique opportunities for reconstruction and clinical research.

Blunt splenic trauma: splenectomy increases early infectious complications: a prospective multicenter study.

Background: The purpose of this study was to evaluate the effect of the method of splenic injury management on early infectious complications. Methods: Prospective observational, multicenter study which included all patients with blunt splenic injury surviving at least 72 hours. Epidemiologic and clinical data, grade of splenic injury, method of splenic management, and infectious complications during the initial hospitalization were collected according to a standardized collecting datasheet. Logistic regression analysis was used to identify independent risk factors for infectious complications. Results: During a 22-month period, 269 eligible patients were enrolled in the study. Overall, 105 (39.0%) patients were observed; 48 (17.8%) underwent successful angioembolization, 19 (7.1%) underwent splenorrhaphy, and 97 (36.1%) underwent splenectomy. Multivariate analysis adjusting for age, hypotension on admission, Glasgow Coma Scale, Injury Severity Score, Abbreviated Injury Scale, laparotomy, grade of splenic injury, and associated solid and hollow viscus injuries, showed that splenectomy had a significantly higher incidence of infectious complications than splenic preservation (adjusted odds ratio [95% confidence interval], 9.62 [3.04–30.30]; p < 0.001). A regression model analysis identified splenectomy, hypotension on admission, associated hollow viscus injury, and high Injury Severity Score as independent risk factors for infectious complications. Forward logistic regression analysis, which included only the 176 patients with grades III to V splenic injuries, identified splenectomy as the most significant independent risk factors for infection (adjusted odds ratio [95% confidence interval], 16.67 [3.76–71.43]; p < 0.001). Conclusions: Splenectomy is an independent risk factor for early infectious complications. Splenic-preserving techniques should be considered more liberally. Level of Evidence: II, therapeutic study.

Early closure of colostomies in trauma patients—A prospective randomized trial

BACKGROUND Most traumatic colon injuries can be repaired primarily, but a colostomy may still be required for severe colonic or rectal injury. The current trend is to reverse the colostomy early, rather than to wait the traditional 3 months before closure. METHODS Forty-nine patients with colostomies after abdominal trauma were entered into the study. All patients had undergone a contrast enema in the second postoperative week to assess distal colon healing. Patients were excluded from early closure for nonhealing of the bowel injury, unresolving wound sepsis, or an unstable condition. We then compared the outcome of the remaining 38 (77.6%) patients allocated to either an early or a late colostomy group in a controlled, prospective, randomized trial. RESULTS We found no significant difference in morbidity between the two groups, with an overall complication rate of 26.3%. Technically the early closure of colostomies was far easier than late closure and required significantly less operating time (p = 0.036) and with less intraoperative blood loss (p = 0.020). The closure of end colostomies was more time consuming, both early (p < 0.001) and late (p < 0.001) and caused more bleeding (p < 0.001 and p < 0.001, respectively). Total hospitalization was marginally shorter overall for early closure, but late closure of end colostomies resulted in prolonged hospitalization (p = 0.023). CONCLUSIONS The early closure of colostomies and the use of loop colostomies whenever possible are recommended as both safe and beneficial for patients with colonic injury after trauma. Contraindications for early closure include nonhealing distal bowel, persistent wound sepsis, or persistent postoperative instability.

Penetrating vascular trauma in Johannesburg, South Africa

An awareness that time crucially affects outcome underpins the principles of management of vascular injury. Patients with hard signs of vascular injury should undergo urgent exploration. Soft signs mandate investigation, and arteriography is still the standard of care. Noninvasive vascular imaging may prove its worth in the future. All patients with penetrating arterial injury should receive broad-spectrum antibiotic prophylaxis. Early repair of carotid artery injury provides the best likelihood of a neurologically intact survivor. There is a definite and emerging role of endovascular therapy both for difficult access injuries and for the later complications of vascular injury, such as false aneurysm and arteriovenous fistulas. The experimental and clinical evidence for the use of intraluminal shunts in peripheral vascular injury is compelling, and experience in their use is accumulating. Vascular trauma is complex and ideally is carried out by experts in a multidisciplinary environment; resuscitation and prompt revascularization are likely to lead to satisfactory outcomes. The major trauma load in South Africa represents an unparalleled experience in management of vascular injury, which seems likely to continue for the foreseeable future.

Penetrating injuries of the iliac arteries : a south African experience

BACKGROUND We did a retrospective study of 62 patients with penetrating injuries of the iliac arteries. METHODS The cause of injury was gunshot wound in 85.5% and stabbing in 14.5%. The arterial repair was achieved by various means: lateral arteriorrhaphy, end-to-end anastomosis, and polytetrafluoroethylene interposition grafts. RESULTS There was a 42% mortality rate from exsanguination or secondary coagulopathy directly related to the arterial injury. Persistent shock, resuscitative thoracotomy, free intraperitoneal hemorrhage, and the number of vascular injuries were directly related to mortality. CONCLUSIONS A high index of suspicion, aggressive resuscitation, and prompt surgery are necessary to improve the chances of surviving this ominous injury.

Gunshot Injuries of the Head of the Pancreas: Conservative Approach

Abstract. This study is comprised of 48 patients with gunshot injuries of the head of the pancreas, many of which were high velocity injuries. The purpose of this study was to evaluate our management policy for these injuries based on our recent wide experience. Patients with grade II and III injuries underwent conservative surgery, with 0% and 21% postoperative mortality, respectively, directly related to the pancreatic injury. For patients in whom the duodenum was involved, pyloric exclusion was applied depending on the grade of the duodenal injury. We concluded that moderate gunshot injuries of the head of the pancreas (grade II) can be safely treated by débridement and suture repair, with or without drainage. Severe (grade IV) injuries warrant a pancreaticoduodenectomy. Most grade III injuries can be treated by débridement and drainage unless an associated severe duodenal injury is present, in which case resection may be indicated.
