Retrospective Observational Study of Post-Operative Analgesia after Total Knee Arthroplasty by Low-Dose Intrathecal Morphine with Peripheral Nerve Block Versus Conventional Intrathecal Morphine : Case Study of Phatthalung Hospital
Keywords:
Total knee arthroplasty, Post-operative analgesiaAbstract
Introduction: Post-operative pain after total knee arthroplasty (TKA) classified as a moderate to severe pain. A faster recovery would be from effective pain management and prevention of complications. Spinal anesthesia is the techniques that typically used in Phatthalung hospital to control pain by low-dose intrathecal morphine (0.1 mg) with peripheral nerve block or conventional intrathecal morphine (0.2 mg)
Objective: To compare efficiency between low-dose intrathecal morphine with peripheral nerve block and conventional intrathecal morphine after total knee arthroplasty in Phatthalung hospital
Material and Methods: A retrospective study of 100 patients in Phatthalung hospital who underwent TKA under spinal anesthesia since 2021 July to May 2022. Time to first dose of morphine, Pain score at rest and move and cumulative morphine consumption in 48 hours were evaluated
Results: 79 patients were included, 41 were received low-dose intrathecal morphine (0.1 mg) with peripheral nerve block and 38 were received conventional dose intrathecal morphine. Time to first dose of morphine in low-dose intrathecal morphine (0.1 mg) with peripheral nerve block group is significantly different to conventional intrathecal morphine. Pain score at rest and move are significantly different. Cumulative morphine consumption in 48 hours is not different.
Conclusion: Post-operative analgesia after TKA is better controlled by low-dose intrathecal morphine (0.1 mg) with peripheral nerve block compare to conventional intrathecal morphine (0.2 mg).
