ABSTRACT
To evaluate the relative effectiveness of three techniques of regional anaesthesia in the provision of postoperative analgesia in children. Methods:
Random assignment of 183 children scheduled for groin surgery to one of three groups. Bupivacaine 0.5 percent plain (2 mg.kgˉ) was injected by the surgeon after skin incision. Group A received wound infiltration. Group B had regional nerve blockade. Group C had a combination of both methods. Post-operatively, pain was assessed using the CHEOPS behavioral scale at half-hourly intervals until discharge home. Satisfactory pain control was arbitrarily defined as CHEOPS score of ≤ six. Potential differences among the groups were sought using graphical presentation of mean pain scores, the frequencies of pain scores, and the incidence of postoperative vomiting and oral analgesic consumption.Results:
Fifteen patients had to be excluded from analysis. This left 61 patients in Group A, 55 in Group B and 52 in Group C. There were no demographic differences among the groups. No differences were demonstrated among the groups either in CHEOPS pain scores at any observation point (P = >0.8), or in the incidence of vomiting or need for postoperative analgesia. (P = 0.52 and P = 0.41 respectively). Overall, 80 percent of the observations made (1135/1425) met our definition of satisfactory pain control. A post hoc calculation of the power of the study confirmed sufficient power to detect a 5 percent difference among groups.Conclusion:
All three methods achieved analgesia with 80 percent of the pain scores meeting our definition of satisfactory pain control. None of the techniques enjoyed any apparent advantage (AU)
