COMPARISON OF THE EFFECTS OF PREEMPTIVE INTRAVENOUS AND RECTAL ACETAMINOPHEN ON PAIN MANAGEMENT AFTER INGUINAL
Insights
Intravenous (IV) and rectal acetaminophen effectively reduced pain and vomiting after pediatric inguinal hernia repair compared to placebo. IV acetaminophen provided the greatest initial pain relief.
Area of Science:
- Pediatric Surgery
- Anesthesiology
- Pharmacology
Background:
- Effective postoperative pain management is crucial in pediatric surgery.
- Acetaminophen is a widely used and safe analgesic for children.
- This study evaluated intravenous (IV) and rectal acetaminophen efficacy for pain after inguinal herniorrhaphy.
Purpose of the Study:
- To compare the analgesic efficacy of IV and rectal acetaminophen against placebo in children undergoing inguinal hernia repair.
- To assess the impact of different acetaminophen formulations on postoperative pain and vomiting.
Main Methods:
- 120 children undergoing elective inguinal hernia repair were randomized into four groups: IV acetaminophen, rectal acetaminophen suppository, IV placebo, and placebo suppository.
- Postoperative pain was measured using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale.
Main Results:
- Both IV and rectal acetaminophen significantly reduced postoperative vomiting compared to placebo (P = 0.04).
- Acetaminophen groups showed significantly lower pain scores than placebo groups during the first two hours post-surgery.
- IV acetaminophen demonstrated the largest analgesic effect within the first hour, with higher sedation levels observed.
Conclusions:
- IV and rectal acetaminophen are more effective than placebo for pain relief following pediatric inguinal hernia repair.
- Both formulations of acetaminophen were associated with a reduced incidence of postoperative vomiting.
- The most significant analgesic benefits of IV and rectal acetaminophen were observed within the initial two hours after surgery.
Background:
Postoperative pain management is a critical concern in pediatric surgery. Acetaminophen is the safest and most widely used analgesic in children. The present study compared the analgesic efficacy of intravenous (IV) and rectal acetaminophen versus placebo in children undergoing inguinal herniorrhaphy.
Methods:
A total of 120 children, who were candidate for elective surgical repair of unilateral inguinal hernia, were enrolled and randomly allocated to four groups of 30 patients each to receive IV acetaminophen, acetaminophen suppository, IV placebo, and placebo suppository during surgery. Postoperative pain scores, measured on the Face, Legs, Activity, Cry, and Consolability (FLACC) scale, were recorded and compared.
Results:
The four groups had no significant differences in the mean age, weight, length of stay in the recovery room, and duration of operation. The frequency of postoperative vomiting was significantly lower in the IV and rectal acetaminophen groups compared to the two placebo groups (P = 0.04). The mean pain scores of the two acetaminophen groups were similar during the first two hours after surgery. These scores were significantly lower than the scores of the placebo groups. However, the four groups were not significantly different in terms of pain scores at the fourth, sixth, and 12th postoperative hours. During the first hour after surgery, IV acetaminophen had the largest analgesic effect. Moreover, among all four groups, the IV acetaminophen group had the highest sedation level in the recovery room.
Conclusion:
Both IV and rectal acetaminophen were more effective than placebo in pain relief after inguinal hernia repair in children. They were also associated with lower frequencies of postoperative vomiting. The greatest analgesic efficacy of both forms was observed during the first two hours after surgery.
