The morbidity and mortality of machete-related injuries is rather appreciable in Nigeria although it is under-reported. Machetes are multipurpose tools in the farm, home and construction sites. Machetes may also be used as a close-range weapon. In Nigeria, there is no legislation guiding their Acquisition, so they are readily available in many homes. Injuries from machetes could be as detrimental as fatal or non-fatal with long-term morbidity. ⋯ Management of machete injuries in a developing nation can be quite challenging. Assault with homicidal intention was the major aetiological factor in our own environment and may be a very important and under-recognised aspect of the injuries. Appropriate injury-prevention mechanisms and other aspects of trauma care are recommended.

Patients undergoing damage control laparotomy need intensive and aggressive resuscitation, and may also require adjunctive transarterial embolisation (TAE) for ongoing arterial haemorrhage. We evaluated the effectiveness and timing of TAE in these patients as well as their final outcome. ⋯ TAE is an effective tool in the management of ongoing arterial haemorrhage after damage control laparotomy and eight (50%) patients with ongoing arterial haemorrhages survived from this multidisciplinary treatment. To achieve a good outcome, the operative time of damage control laparotomy should be as short as possible and TAE should be performed without delay. Interventional radiology colleagues should be informed in advance during laparotomy and resuscitation continued in the angiography suite.

Venous thromboembolic events (VTEs) are common life-threatening complications after trauma, but epidemiology and reported risk factors still vary. The purpose of this investigation was to determine the incidence of VTEs among hospitalised trauma patients, to identify potential risk factors and to assess whether their presence was associated with: (a) the magnitude and pattern of injury, (b) therapeutic interventions and (c) outcome, all by using a large population-based registry. ⋯ The occurrence of clinically apparent VTEs during post-traumatic hospitalisation is low but associated with increased morbidity and mortality. Conclusions about the effectiveness of different thromboprophylactic measures could not be drawn, since detailed information was not recorded. However, 80.8% of VTE patients had received thromboprophylaxis at the time point of the event.

Colonic and intra-peritoneal rectal injuries may be managed by primary repair and extra-peritoneal rectal injuries by diverting colostomy. This study was undertaken to document our experience with this approach and to identify factors which might impact on outcome. ⋯ We reaffirm that primary repair is appropriate for colonic and intra-peritoneal rectal injuries and that extra-peritoneal rectal injuries require diverting colostomy. Shock on admission, increased blood transfusion requirements, associated organ injury and severity of the injury were associated with high mortality.

The age of a patient, lowest pre-operative pH and lowest core temperature are significant predictors of mortality in patients undergoing damage control surgery (DCS). An equation had previously been devised based on these three variables, which could predict which patients would die despite undergoing DCS (100% positive predictive value, 25% sensitivity). The aim of this study was to validate this equation by testing it on a different cohort of patients undergoing DCS. ⋯ Both the positive predictive value and sensitivity of the equation remain consistent. When resources are overwhelmed by multiple casualties, this equation could prove useful in identifying patients in whom surgery may be futile, allowing surgical triage to be directed in a more efficient manner.
