Plasma concentrations of alpha-atrial natriuretic peptide (alpha-ANP), antidiuretic hormone (ADH) and aldosterone (ALDS) were determined by radioimmunoassay in 9 patients undergoing aortocoronary bypass grafting under high dose fentanyl (94.4 micrograms.kg-1) anesthesia. These three levels in pre-anesthetic period (control values) were within normal ranges suggesting the absence of congestion and dehydration. ⋯ Present results indicate that high dose fentanyl anesthesia cannot suppress ADH and ALDS level during CPB as was previously demonstrated and the observed rise in alpha-ANP level is considered to be inadequate not only for diuresis but also for vascular dilatation. Administration of alpha-ANP to ameliorate circulatory insufficiency after CPB should probably be considered.

The present system of French emergency medicine and its philosophy were described from my experience at SAMU (service d'aide medicale urgente). Three factors of emergency medicine; pre-hospital care, emergency transport and emergency information service are managed by anesthesiologists. Anesthesiologists on duty at the tele-medicine center give medical team instructions to start at once. ⋯ They start to give intensive care medicine to critically ill patients on the spot. The philosophy of SAMU is that doctors should go out of the hospital. Anesthesiologists in the area organize the emergency medical system in France.
