Effect of induced acute mild arterial hypertension on postoperative analgesic requirements after laparoscopic ovarian
Objective:
To evaluate the effectiveness of inducing acute hypertension during laparoscopic ovarian cystectomy on postoperative nalbuphine analgesic requirements.
Methods:
The total dose of nalbuphine used in the hypertension group was significantly lower than that in the control group (p <0.001). The VAS score was significantly lower in the hypertension group on arrival to PACU and during the period between 1 and 6 hours postoperatively.
Results:
The total dose of nalbuphine used in the hypertension group was significantly lower than that in the control group (p <0.001). The VAS score was significantly lower in the hypertension group on arrival to PACU and during the period between 1 and 6 hours postoperatively.
Conclusion:
This study demonstrates that pharmacologically induced mild acute intraoperative hypertension significantly reduces postoperative nalbuphine consumption and pain scores following laparoscopic ovarian cystectomy. Trial registration in Pan African Clinical Trial Registry: identification number for the registry is PACTR201508001247179.
