Effect of Ultrasound-Guided Transversus Abdominis Plane Block Combined with Lornoxicam on Pain and Recovery Quality After Abdominal Surgery in Patients with Drug Addiction

Abstract

Objective: This paper aims to analyze the analgesic effect of ultrasound-guided transversus abdominis plane block (TAPB) combined with non-steroidal anti-inflammatory analgesic drug lornoxicam on abdominal surgery in patients with a history of drug addiction. Methods: 32 patients aged 18–60 who underwent lower abdominal surgery in the First People’s Hospital of Liangshan Yi Autonomous Prefecture and Butuo County People’s Hospital of Liangshan Yi Autonomous Prefecture from January 2022 to March 2023 were selected, the patients must have drug abuse history for more than 1 year, with a history of drug withdrawal and relapse. The patients were divided into observation group and control group by the envelope method, with 16 cases in the observation group and 16 cases in the control group. Two groups of patients underwent ultrasound-guided bilateral transversus abdominis plane block after the operation. The observation group was treated with dexmedetomidine hydrochloride 1μg/kg + 0.25% ropivacaine hydrochloride 40ml, and the control group was treated with 40ml 0.9% sodium chloride injection, the two groups of patients returned to the ward after operation and given intravenous infusion of lornoxicam for relieving the pain. The visual analogue scale(VAS) score of postoperative pain, the times of rescue analgesia, the time of postoperative anal exhaust, the time of ambulation, nausea and vomiting, withdrawal symptoms, related adverse reactions, and hospitalization days were compared between the two groups. Results: The VAS score of postoperative pain in the observation group was significantly lower than that in the control group, P < 0.05. Patients in the observation group used less postoperative rescue analgesics than those in the control group, P < 0.05. For postoperative anal exhaust time, the difference between the two groups of patients was relatively small, and the time in the observation group was shorter, P > 0.05. The time to get out of bed and the length of hospital stay were not significantly different between the control group and the observation group, P > 0.05. The withdrawal symptoms of the patients in the observation group were better, P < 0.05, nausea and vomiting, and other adverse reactions were lower in the control group, P < 0.05. Conclusion: Ultrasound-guided transversus abdominis plane block combined with lornoxicam can be used to relieve pain in abdominal surgery for patients with drug addiction, which can effectively improve the therapeutic effect of patients and reduce the number of postoperative rescue analgesia. Thus, it has high clinical application value.
