Postoperative pain is a common complication in patients undergoing major surgical operations, interfering with comfort and recovery and increasing the risk of further complications. This study aimed to evaluate the effectiveness of NSAIDs in managing postoperative pain at Manokwari Regional Hospital. Utilizing qualitative research methods, data was collected through observation and literature study and analyzed via data reduction, data presentation, and conclusion drawing. The findings indicate that NSAIDs effectively alleviate postoperative pain by inhibiting cyclooxygenase (COX) enzymes responsible for prostaglandin production. However, their use is limited by potential systemic side effects, including gastrointestinal disorders, kidney impairment, increased blood pressure, heart attack, and heart failure. Consequently, topical NSAID formulations are recommended to mitigate these risks. The study suggests that while NSAIDs are effective, clinicians should consider their side effects and prefer topical alternatives. Future research should explore the efficacy and safety of topical NSAIDs and alternative pain management strategies to enhance clinical practice.
