Abstract
The effect of epidural blockade on the metabolic and hormonal responses to pelvic surgery was investigated in 14 female patients. Central venous blood samples were collected every 30 minutes and analysed for free fatty acids, glycerol, β-hydroxybutyrate, acetoacetate, glucose, lactate, pyruvate, cortisol and growth hormone concentrations. There was no change in fat and glucose metabolism except for a transient decrease in lipolysis after 30 minutes of surgery. Cortisol and growth hormone values were significantly increased (p < 0.01) after 60 minutes. A small but statistically significant increase in blood lactate concentration was observed (p< 0.01) and the concept of a “metabolic V/Q” abnormality is postulated to explain the lacticacidaemia. Ľeffet du bloquage épidural sur les réponses métabolique et hormonale provoquées par la chirurgie du bassin a été étudié chez 14 patientes. Des échantillons de sang veineux central ont été prélevés et analysés dans le but de doser les acides gras libres, le β-hydroxybutyrate, ľacéto-acétate, le glucose, le lactate, le pyrunate, le cortisol et ľhormone de croissance. Aucun changement dans le métabolisme lipidique et glucidique n’a été noté à ľexception ďune baisse transitoire de la lipolyse après 30 minutes de chirurgie. Quant au cortisol et à ľhormone de croissance, leur concentration a subis une hausse significative (p < 0.01) après 60 minutes. Une augmentation significative bien que faible a aussi été notée pour le lactate sanguin (p < 0.01); le concept du pliquer cette lactacidémie.This publication has 13 references indexed in Scilit:
