Effect of Epidural Anesthesia and Analgesia on Quality of Recovery After Unilateral Nephrectomy.

Summary

Different modality of anesthesia and analgesia could influence a postoperative quality of recovery (QoR). This study is exploring early QoR after unilateral nephrectomy in the two groups of anesthesia. The first group had a light general anesthesia with thoracic epidural anesthesia and postoperative epidural analgesia with morphine and ropivacaine. The second group had general anesthesia and a continuous postoperative analgesia with tramadol. The postoperative QoR was evaluated 24 hours after surgery.

Interventions

PROCEDURE

Epidural anesthesia with light general anesthesia

Epidural anaesthesia: mixture of ropivacaine 6.5 mg/ml and fentanyl 8.3 μg/ml. Light general anesthesia: isoflurane in mixture of 50/50 of nitrous oxide and oxygen to achieve Minimum alveolar concentration between 0.6 and 0.8.

PROCEDURE

Postoperative epidural analgesia

Before the end of operation was given 4 ml of the mixture of ropivacaine 4.4 mg/ml and morphine 0.8mg/ml. Epidural analgesia was continued for next 24 hours with a mixture of ropivacaine 2.2 mg/ml and morphine 0.4 mg/ml.

PROCEDURE

General anesthesia

Maintaining general anesthesia: nitrous oxide and oxygen in mixture 50/50 and isoflurane to achieve minimum alveolar concentration between 0.8 and 1. Fentanyl loading dose: 6-8 μg/kg. Additional fentanyl doses were given incrementally.

DRUG

Continuous intravenous analgesia

Tramadol 100 mg in the first hour followed by tramadol 300 mg continuously for the next 24 hours.
