Les garrots de prélèvement, un drame chez le nourrisson: à propos de 3 cas

The time limit for the removal of a tourniquet is short; any delay in tourniquet deflation, especially if it exceeds the 3 hour limit, exposes to amputation hazards. Our objective was to report three cases of ischemic limb gangrene, caused by having forgotten to take a tourniquet off after a blood sampling, to inform healthcare professionals about the risk associated with that negligence. We encountered 3 cases of infants (2 three-month-old infants and 1 five-month-old infant), hospitalized in intensive care unit of Yalgado Ouédraogo University Hospital for upper-left limb swelling. Their medical history shows that there was a delay in tourniquet deflation after a blood sampling of 24 hours in two cases and of 48 hours in one case. Physical examination revealed a diffuse edema associated with upper limb gangrene spread to the mid-third of the upper arm, abolition of the ulnar and radial pulse as well as loss of sensation in the hand in 2 cases. In one case clinical signs were attenuated. The diagnosis of ischemic limb gangrene was confirmed in all cases. Laboratory examinations were normal. Two cases needed urgent trans-humeral amputation and one case needed debridement plus amputation of four fingers. The evolution was simple in all cases. Iatrogenic dry gangrene caused by a delay in tourniquet removal should never happen at hospitals. This can be guaranteed only by tightening up health management and by performing regular and accurate patient monitoring.
