Comparing the Efficacy and Side Effects of Intravenous Ibuprofen and Acetaminophen in Pain Control Following Laparoscopic Cholecystectomy.

BACKGROUND

The importance of using effective postoperative analgesia is widely accepted. Systemic opioids are the gold standard for reducing severe pain after surgery, but the side effects have limited the use of adequate doses. We aimed to evaluate the effect of adding intravenous acetaminophen and intravenous ibuprofen to fentanyl on patient-controlled analgesia.

METHODS

In this randomized clinical trial study in Ardabil city hospital at 2019, 90 patients undergoing elective laparoscopic cholecystectomy were randomly divided into three groups. The control group (n=30) received normal saline, the acetaminophen group (n=30) received 1g intravenous acetaminophen, and the ibuprofen group (n=30) received 800 mg intravenous ibuprofen. All patients received a pain control by intravenous pump containing fentanyl (15µ/ml). The drugs were injected intravenously after surgery. Shoulder and abdominal pain scores, sedation rate, nausea and vomiting, satisfaction, and the doses of fentanyl and meperidine were recorded in SPSS software within 24 h after surgery.

RESULTS

The mean abdominal pain scores in ibuprofen (3.02) and acetaminophen (2.89) groups were not significantly different (P=0.719) but were significantly lower than in the control group (5.10) (P<0.001). The severity of shoulder pain, nausea and vomiting, sedation, and fentanyl intake were not significantly different in the ibuprofen and acetaminophen groups but were significantly lower than in the control group.

CONCLUSION

The use of both intravenous acetaminophen and ibuprofen in pain control after surgery can reduce the need for opioid use. Acetaminophen can also be a suitable alternative for postoperative pain control in patients that are unable to use NSAIDs.
