Acupuncture and Postoperative Pain Reduction

Postoperative pain is a universal concern for patients undergoing medical procedures, and it has traditionally been managed primarily with analgesic medications, including opioids. However, prolonged use of these substances can lead to dependence and unwanted side effects. In this context, acupuncture, an ancient technique originating from Eastern medicine, has gained increasing recognition in Western medicine as a promising complementary alternative for postoperative pain control. This long-standing practice, which involves the insertion of fine needles at specific points on the body, has been increasingly integrated into surgical care protocols at hospitals around the world, representing a more holistic and potentially safer approach to pain management.

The study conducted by Shah and colleagues had as its main objective to synthesize and analyze the most recent scientific evidence on the use of different acupuncture techniques for pain control during the perioperative period, which encompasses the moments before, during, and after surgery. The researchers conducted a narrative review of the scientific literature, examining studies that investigated various acupuncture modalities applied to surgical patients. The review method allowed the authors to compile and analyze data from multiple studies conducted in different patient populations undergoing various types of surgical procedures. This methodological approach was chosen to provide a comprehensive view of the current state of knowledge on the topic, identifying both the benefits and the limitations of the different acupuncture techniques in the hospital setting.

The results of the analysis revealed encouraging findings regarding the efficacy of acupuncture in different surgical contexts. The patients who benefited most significantly from the interventions were those undergoing abdominal surgeries, spinal and nervous system procedures, and pelvic gynecologic surgeries. Among the various acupuncture techniques studied, three modalities stood out for their efficacy: electroacupuncture, which combines traditional needle insertion with low-intensity electrical stimulation; transcutaneous electrical acupoint stimulation, a noninvasive technique that applies electrical stimuli through the skin; and traditional whole-body acupuncture, which uses multiple points distributed throughout the body. The benefits observed were multiple and clinically relevant, including significant improvement in pain control, reduction in the need for narcotic medications, decrease in postoperative nausea and vomiting — a common and uncomfortable complication after anesthesia — and faster recovery of normal bowel function, which is particularly important after abdominal surgeries.

The clinical implications of these findings are substantial both for patients and for healthcare providers. For patients, acupuncture represents a therapeutic option with a very favorable safety profile, presenting minimal risks when performed by qualified practitioners. This means they can experience pain relief with less reliance on opioid medications, thereby reducing the risk of side effects such as constipation, excessive drowsiness, mental confusion, and, in the long term, chemical dependence. The decrease in postoperative nausea and vomiting also contributes significantly to patient comfort and satisfaction during the recovery period.

For healthcare providers, especially anesthesiologists, surgeons, and nursing teams, acupuncture offers a valuable tool for implementing multimodal analgesia protocols, an approach that combines different pain control methods to maximize efficacy and minimize adverse effects. This integration may result in shorter hospital stays, lower incidence of opioid-related complications, and greater overall patient satisfaction with their care.

Despite the promising results, the study also identified important limitations that should be considered. The diversity of patient populations studied, the variety of acupuncture techniques used, and the relatively small size of most of the studies analyzed make it difficult to determine which specific technique would be most beneficial for each type of patient or surgical procedure. This heterogeneity in the data also limits the ability to make precise recommendations regarding standardized treatment protocols. The authors emphasize the need for future research with larger patient samples and prospective studies that directly compare different acupuncture techniques, which would allow better characterization of the specific role of each modality in perioperative pain management.

Until such studies are conducted, the implementation of acupuncture should be done on an individualized basis, considering the specific characteristics of each patient and the type of surgery to be performed, always as part of an integrated approach to care that includes conventional pain control methods.
