Propofol Versus Sevoflurane on Acute Postoperative Pain

Postoperative Pain Clinical Trial

Official title: A Comparison of Propofol-remifentanil Versus Sevoflurane-remifentanil: the Effect on Acute Postoperative Pain After Total Shoulder Arthroplasty

Status Completed

Clinical Trial Summary

This study was performed to compare the acute postoperative pain intensity and opioid consumption after total shoulder arthroplasty between propofol-remifentanil and sevoflurane-remifentanil anesthesia.

Clinical Trial Description

After approval of the Institutional Review Board and written informed consent, 48 patients, aged 18-65 years for shoulder arthroplasty were enrolled in this prospective, randomized, double-blinded study.

Patients were assigned to one of two groups : group PR, the propofol-remifentanil group; and group SR, the sevoflurane-remifentanil group.

In the group PR, anesthetic induction was achieved with an initial target concentration of propofol 4 ㎍/mL and remifentanil 3-4 ng/mL using target controlled infusion (TCI) devices and rocuronium 0.8 mg/kg. After intubation, anesthesia was maintained with fixed target concentration of propofol 2-4 ㎍/mL and remifentanil 2-3 ng/mL to keep acceptable hemodynamic response and bispectral index (BIS) values 40-60.

In the group SR, anesthetic induction was achieved with thiopental 5 mg/kg and initial target concentration of remifentanil 3-4 ng/mL using TCI and rocuronium 0.8 mg/kg. Anesthesia was maintained with 1.5-2.5% end-tidal concentration sevoflurane in 50% oxygen with air and remifentanil 2-3 ng/mL was continuously infused adjusting to maintain an acceptable hemodynamics and BIS values 40-60.

The administration of propofol or sevoflurane with remifentanil was stopped at the surgery ended.

Postoperative pain intensity was assessed using a numerical rating scale (NRS: 0; no pain, 10; worst pain) at the 30 min, 2, 6, 12, 24 h. Also, the patient-controlled analgesia (PCA) was infused immediately after post anesthetic care unit arrival. The PCA device was set to deliver 0.38 ㎍/kg/h of fentanyl as a basal infusion rate and 20 ㎍ on demand with a 15 min lockout time. The total PCA volume, number of patients to need rescue analgesics was recorded. ;
