There have been limited reports on machete wounds to the cranium. This study was carried out to document the injury profile in a series of patients who have sustained cranial injuries from machete wounds in this setting. Between 1 January 1998 and 1 January 2008, demographic and clinical data were retrospectively collected from all patients treated with complicated head injuries from machete wounds with at least one of the following clinical or radiological features: a recorded Glasgow Coma Score < 8 at any point during admission; compound skull fractures; protruding brain matter; cerebrospinal fluid (CSF) leaks; intra-cranial bleeding; parenchymal contusions; lacerations and/or oedema. The data were analysed using the SPSS version 12.0. Of the 40 patients with complex injuries to the cranium, there was a 6:1 male preponderance with a mean age of 32.5 ± 13.7 years (Mean ± SD). The injuries included open skull fractures in all the 40 (100%) patients, depressed skull fractures in 20 (50%) patients, CSF leaks in 4 (10%) patients, protruding brain matter in 4 (10%) patients, cerebral contusions in 3 (7.5%) patients and extra cranial injuries in 16 (40%) patients. Tetanus prophylaxis and intravenous antibiotics were administered to all patients, and phenytoin was required in 16 (40%) cases. There were 37 (92%) patients requiring operative intervention at a mean of 10.4 h after presentation (SD ± 18.1; Median 6). The operative procedures included elevation of depressed fractures in 20 (54.1%) patients, dural repair in 10 (27.0%) patients and intra-cranial debridement in 7 (18.9%) patients. There were three deaths (7.5%), and seizures were recorded in 5 (12.5%) cases with no reports of infectious morbidity. Eighty percent of patients had a normal Glasgow outcome score on discharge. Complicated machete head trauma is uncommon at this health care facility in Jamaica. We achieved a satisfactory outcome with aggressive management consisting of prompt assessment of the extent of injury, appropriate antibiotics, anticonvulsants for those with seizures or cortical injury and early operation to decrease the risk of complications.
