Kidney function after methoxyflurane analgesia during labour.

Abstract

In a study of the effects of methoxyflurane on renal function, the urinary and blood urea concentrations, the urinary and plasma osmolalities, and the packed cell volume were studied in each of 50 mothers before and after delivery. Methoxyflurane 0.35% was used as an analgesic in 25 patients and the other 25 had 50% nitrous oxide and 50% oxygen (Entonox). There was no evidence of renal dysfunction in either group, nor were there any significant differences between the groups. In a further 200 mothers, of whom 100 had methoxyflurane and 100 had nitrous oxide analgesia, the urinary and blood urea concentrations were measured on the morning of discharge from hospital. There were no significant differences between the groups. These results suggest that methoxyflurane is not nephrotoxic when used as a self-administered analgesic.
