[The effects of preoperative anxiety on anesthetic recovery and postoperative pain in patients undergoing donor nephrectomy].

Background And Objectives: It is suggested that 38-45% of patients experience preoperative anxiety. We observe that patients undergoing living donor nephrectomy suffer from anxiety. Preoperative anxiety may complicate a patient’s recovery from anesthesia and postoperative pain control. This study investigates the preoperative anxiety rate and its effect on anesthetic recovery and postoperative pain in patients undergoing donor nephrectomy.

Methods: Forty-eight individuals undergoing living-related renal donor nephrectomy were included in this analytic prospective observational cohort study. Their preoperative anxiety was measured with the STAI-I and STAI-II inventories. The relationships between anxiety scores with data regarding demographics, recovery from anesthesia, and postoperative pain scores were investigated.

Results: The findings were remarkable in that the anxiety scores of living renal donors were significantly correlated with their recovery variables, which are spontaneous respiration time, sufficient respiration time, extubation time, and PACU discharge time ( < 0.01). Anxiety scores were significantly positively correlated with the pain scores of the 30th minute, 1st, 2nd, 4th, 8th, 12th, 24th hours, and the total amounts of analgesic administered in 24 hours ( < 0.05). A significantly negative correlation was also determined between anxiety scores and patients’ satisfaction.

Conclusion: Our study showed that patients undergoing living-related donor nephrectomy with high anxiety levels had late recovery times and high postoperative pain scores. Thus, determining those patients with high preoperative anxiety level is crucial to providing patients with satisfactory emerging from anesthesia and the control of their postoperative pain during donor nephrectomy.
