Abstract
Introduction:
The purpose of this trial was to determine the efficacy of a Nurse Controlled Analgesia (NCA) protocol in reducing the time taken to achieve a satisfactory postoperative pain score. The safety aspects of the NCA protocol were also evaluated.
Method:
120 patients undergoing major surgery were randomised into 2 groups – NCA group and the doctor administered analgesia group (DRA). Nurses in the Post Anaesthestic Care Area (PACU) administered analgesia based on a protocol whereas analgesia was titrated at the discretion of the doctor in the DRA group.
Effective pain control was measured by the time taken to obtain first dose of analgesia and the time taken to achieve either a pain score of less than 4/10 or if the patient refused further analgesia.
Results:
Patients received their first dose of morphine faster in the NCA group compared to DRA group, 6.7 minutes versus 9.5 minutes respectively (p= 0.037). Time taken to achieve a pain score of less than 4 was shorter in the doctor group although this was not significant. Complication rates were not different in both groups.
Conclusion:
Nurse administered analgesia based on a protocol can provide pain relief for patients in the postoperative period as effectively and safely as doctor administered analgesia.
