Post-operative critical care and outcomes of limb replantation: experience in a developing country.
Replantation is the treatment of choice for traumatic amputation. Its success rates vary, reaching 80% in world's best centres. This study analyses management practices of replantation in a regional centre in a developing country. Out of six replantations, four were successful. The median warm ischaemia time of the severed limb was 4.5h (range 1-13.5) and the median duration of general anaesthesia required for initial surgery was 6.25h (range 4.7-8.0). All patients needed intensive care following replantation for a median of 7 days (range 5-15). Pulse oximetry values were observed to be the same in the graft and the patient in successful cases. Two grafts failed. The median haemoglobin values on the 1st, 3rd and 5th post-operative day were 9.8, 7.0 and 8.4g/dl, respectively. The median platelet counts in the same time periods were 118x10(9), 68x10(9) and 205x10(9)L(-1). The median total fluid intake was 2.2, 3.1 and 3.4ml/kg/h on the 1st, 3rd and 5th post-operative day and the median urine output was 2.4, 2.6 and 2.7ml/kg/h, respectively. The observed post-surgical reduction in platelet count normalised by the 5th post-operative day. Higher fluid intake and lower haemoglobin levels appear to minimise the systemic effects of reperfusion injury, preventing the onset of renal failure and promoting graft perfusion. Pulse oximetry was a useful tool to assess graft perfusion and appear to offer a prognostic value. Three of the above 4 patients were traced for review 5 years later and had functioning grafts.
