clove and Heart-Arrest

To evaluate the risk of the practice of spinal anaesthesia (SA) in African tropics.. Prospective study in multiple centres over a two years period.. Twenty-one anaesthesiologists and anaesthetist nurses covering ten African countries.. Two anonymous questionnaires; the first, filled in each anaesthetic problem occurred, to define the type of incident or accident, and its circumstances; the second was designed to define the position occupied, to quantify the global anaesthetic activity, the number of SA, and to value the number of complications or deaths linked to SA.. Six anaesthesiologists and one anaesthetist nurse replied to the study, covering six sites in five different countries (Senegal, Chad, Central African Republic, Niger and Madagascar). On the 18,432 anaesthetic acts collected, 2,703 (14.7%) were SA. In the well-equipped centres, general anaesthesia was predominant with a frequency of over 75%. However in the not so well equipped centres or those which supplies were more problematical, SA technique was used with a frequency varying from 48.9 to 68.7%. Forty incidents and accidents were reported (1.5%), five led to the death of the patient (0.2%). Among the seven cardiac arrests (0.3%), four were fatal (0.1%). Eight of the ten accidents and all of the deaths occurred in the least equipped centres. Eight of ten accidents happened during emergency caesarean sections. All cardiac arrests were preceded by a severe hypovolemia. For the four deaths after cardiac arrest, an anaesthetist nurse with isobaric bupivacaine 0.5% carried out SA.. This study showed that the practice of SA in African tropics was performing in different practice conditions and people qualification than they were in France. The frequency of cardiac arrests and deaths was respectively five and 20 times more important, in those conditions. The first conclusion that can be drawn from this study is that it is questionable to use SA for emergency Caesarean section under hypovolemic condition. The second is the necessity for specific training on the local anaesthesia for anaesthetist nurses but also training to choose the anaesthesia best adapted to the surgery, the condition of the patient and the means available.
