NCT05655806

Brief Summary

To determine optimal dose, method and time of administration of aminophylline to enhance the recovery from general anesthesia. andTo estimate the recovery time from isoflurane closure in each group. We hypothesize that starting administration of loading and maintenance dose of aminophylline half an hour before discontinuing isoflurane will shorten the duration needed to extubate patients undergoing lumbar disc surgery. We hypothesized that it will yield superior results compared to bolus administration after discontinuing isoflurane.

Study Arms (3)

group A

ACTIVE COMPARATOR

will receive aminophylline loading dose 5mg/kg on a 50 cm syringe using syringe pump over 5 minutes and maintenance dose 1.5 mg/kg/hr as a continuous infusion half an hour before discontinuation of isoflurane, and after discontinuation of isoflurane a 5 cm syringe of saline will be given over 5 minutes

Drug: Aminophylline bolus then infusion

group B

will receive a 50 cm syringe of saline using syringe pump over 5 minutes and maintenance continuous infusion of saline half an hour before discontinuation of isoflurane, and after discontinuation of isoflurane a 5cm syringe of aminophylline bolus 5mg\\kg will be given over 5 minutes

Drug: aminophylline bolus
