Summary

The aim of this prospective, interventional, randomized trial is to compare the effectiveness of postoperative analgesia using single-dose intrathecal morphine and intravenous morphine in patients undergoing liver resection. The study is to include a total 36 patients randomized in a 1:1 ratio into two groups. The study will be single-blinded with respect to outcome assessors. Patients in the experimental group (n=18) will receive a single dose (0,4 mg) intrathecal morphine immediately before operation and patient-controlled analgesia (PCA) with morphine over first 24 postoperative hours and subcutaneous morphine (5 mg in case of numerical rating scale\>4) over next two days in the postoperative period. Patients in the control group (n=18) will receive a single dose of intravenous morphine (0,15 mg/kg body mass) immediately after the operation and PCA with morphine over first 24 postoperative hours and subcutaneous morphine (5 mg in case of numerical rating scale\>4) over next two days. Both groups will receive antiemetic prophylaxis with dexamethasone (4 mg) and ondansetron (4 mg) and standard baseline analgesia with paracetamol (1,0 g every 6 hours) and dexketoprofen (50 mg every 8 hours). Severity of pain at rest evaluated with numerical rating scale twice daily over 3 first postoperative days will be the primary outcome measure. Secondary outcome measures will include: severity of pain at coughing evaluated with numerical rating scale twice daily over 3 first postoperative days, total dose of morphine administered with PCA, time to patient mobilization, grade of sedation, intestinal motility, solid food intake tolerance, duration of hospitalization, and postoperative complications.

Conditions

Interventions

PROCEDURE

Intravenous morphine

Single dose of intravenous morphine (0,15 mg/kg body mass) immediately after the operation, patient controlled analgesia with morphine (2 mg intravenously, a least 20 min interval) over first 24 postoperative hours and subcutaneous morphine (5 mg in case of numerical rating scale\>4, at least 6 hour interval) over next two days

PROCEDURE

Intrathecal morphine

Single dose (0,4 mg) intrathecal morphine immediately before operation, patient-controlled analgesia with morphine (2 mg intravenously, a least 20 min interval) over first 24 postoperative hours and subcutaneous morphine (5 mg in case of numerical rating scale\>4, at least 6 hour interval) over next two days in the postoperative period
