Abstract
Background Opioids, which have well-known adverse effects such as drowsiness paralytic ileus and respiratory depression, were mostly utilised to treat postoperative pain in the past. The increased incidence of side effects has led to a rise in interest in pain management techniques that spare opioids. Persistent abdominal pain following surgery has a major detrimental effect on patients' quality of life. While epidural analgesia is widely regarded as the gold standard to combat the pain that is present post abdominal surgeries, it is not devoid of drawbacks. The transversus abdominis plane (TAP) block has developed as a potentially effective treatment for severe abdominal pain. The TAP block acts on the neuro-fascial plane between the internal oblique and transversus abdominis muscles, which is innervated by spinal nerves from T6 to L1. Studies reveal that the addition of corticosteroids to bupivacaine in TAP blocks provides pain relief and improves the quality of life of the patient. Aims and objectives In this study, the effects of bupivacaine and corticosteroids, particularly dexamethasone and methylprednisolone, on chronic abdominal pain following surgery are examined. Assessing the quality of pain relief is the primary objective. Methodology Thirty patients who had undergone abdominal surgery and had been having persistent abdominal pain for six to eight months thereafter and had attempted unsuccessfully to treat the pain with alternative pain relief methods participated in the study. They were divided into two groups at random. Dexamethasone and bupivacaine were given to patients in Group D while methylprednisolone and bupivacaine were given to patients in Group M for ultrasonography (USG)-guided bilateral TAP blocks. At various intervals up to 12 weeks after injection, the patient's pain levels were measured using the visual analogue score (VAS), and their quality of life was assessed using the quality-of-life score. Results Patients in Group M experienced significantly less pain than those in Group D at the fourth, sixth, and 12th weeks of treatment. Furthermore, in the fourth, sixth, and 12th weeks, patients in Group M reported a superior quality of life in comparison to those in Group D. Conclusion Patients with persistent postoperative abdominal pain receiving bupivacaine and methylprednisolone in an ultrasonography-guided TAP block experience more effective and long-lasting pain relief than those who receive bupivacaine and dexamethasone. The quality of life for patients may be enhanced by using corticosteroids to optimise postoperative pain management strategies and lessen the need for opioids, as this study highlights.
