Postoperative pain management in geriatric patients after cholecystectomy and studies of glycemia and cortisol levels.

Objective: The purpose of the study was to follow up the cortisol levels in relation to the postoperative pain intensity, its levels after treatment with opiate and non-opiate analgesics, and to monitor the relationship between the blood glucose and cortisol levels. Another goal was to optimize the postoperative analgesia of geriatric patients with the known combinations of analgesics.

Methods: The cohort comprised 28 geriatric patients undergoing laparoscopic cholecystectomy.
