[Withholding or withdrawing of life sustaining therapies in emergency context. Perception by anaesthesiologists]

One objective is to state more accurately the difficulties met by the anaesthesiologists in an emergency context in case of withholding or withdrawing life sustaining therapies.

A questionnaire addressed to anaesthesiologists of nine hospitals in the extreme West part of France.

The questionnaires were sent and returned by mail in order to guarantee confidentiality.

The participation rate was 40% with 172 questionnaires analysed. Ninety-eight per cent of the anaesthesiologists have already participated in a withholding or withdrawing life sustaining treatments, and in an emergency context in 92% of the cases. In that last case, criteria related to the severity of the clinic presentation and to the short-term death probability influence the decision made to interrupt life-sustaining therapies. For 93% of anaesthesiologists, the decision should be collegial, but 50% of them had already made such a decision alone. The withdrawal of ventilatory support was the most difficult decision to make. Withdrawing mechanical ventilation or extubating appeared impossible for 23.4 and 50% of the anaesthesiologists respectively. Providing comfort care to the patients with end of life decision was essential for 100% of the anaesthesiologists, but 11% of them used and considered analgesic and sedation after withholding or withdrawing life sustaining treatments as euthanasia. The complaint possibility worried 57% of the anaesthesiologists and influenced the writing of the process or giving information to the families respectively for 65 and 75%. The righting of the medical files could be improved for 92% of the anaesthesiologists.

The decision of withholding and withdrawing life sustaining treatments in an emergency context is based on the conviction of short-term death probability. Withholding and withdrawing life sustaining treatments is a decision made according to the principles of collegiality and necessary comfort cares, but the procedure can still be improved, especially in the redaction of the medical file and the ethical and juridical control of these extreme situations.
