Traitement preventif des hypotensions arterielles au cours de la rachianesthesie

ABSTRACT

The prevention of blood pressure fall during a conventional spinal anaesthsia is based on the use of adrenergic vaso-constrictor and/or vascular filling. The aim of our prospective study is to evaluate the respective efficiency of ephedrin and vascular filling in the preventive treatment. 100 patients who would submit a surgical treatment of a groin hernia were included in the study. Thses patients were divided into two groups Group E [n = 50] 10 ug Kg-1 min-1 of ephedrin received 5 min before the puncture; Group R [n = 50] 8 ml Kg-1 of cristalloids received 20 min before the puncture. Within Group E, 18% of patients have developed a blood pressure fall against 42% within Group R. Stastiscally, the difference is significant [P < 0,05]. The preventive administration of ephedrine seems to be efficient in the reduction of the blood pressure fall incidence during the conventional spinal anaesthesia
