Postoperative Analgesia Using Psoas Sheath Block Versus Three-in-One Block in Anterior Cruciate Ligament Reconstruction
Abstract
In this study, the effects of two regional anesthetic techniques on postoperative pain of patients undergoing anterior cruciate ligament reconstruction surgery were described. Patients were assigned the morning of surgery to one of two groups. Subjects in Group A received a psoas sheath and sciatic nerve blocks and subjects in Group B received a three-in-one and sciatic nerve block. Additionally, all subjects received either a propofol infusion for sedation or a general inhalational anesthetic. Sixteen subjects were enrolled, 12 in Group A and four in Group B. Mean time from the end of surgery to the patients first request for pain medication was 7.7 hours(SD 1.9) for Group A and 11 hours (SD 1.1) for Group B. Mean time to administer the regional nerve blockade for was 15.3 minutes (SD 7.5; range 7-30) and 23.5 minutes (SD 9.9; range 15-25) for Group A and B respectively. The regional techniques for Group A (n=12, 2=no data) resulted in blockade of all nerves for 8 of the10 (80%) subjects. The regional techniques for Group B (n=4) yielded two cases which no nerves were blocked and two cases where all nerves were blocked.
