Review Case Reports Comparative StudyStroke, regional anesthesia in the sitting position, and hypotension: a review of 4169 ambulatory surgery patients.
Despite frequent incidence of hypotension, no cases of stroke were observed in this audit of 4,169 shoulder surgeries performed in the beach-chair position. Notably though, 97% of the cases were performed under brachial plexus block with intravenous sedation rather than a general or relaxant technique.
The authors estimate the upper limit incidence of stroke in the sitting position under regional anaesthesia as 1 in 1,429 (0.07%).

Randomized Controlled Trial Comparative StudyDoes continuous sciatic nerve block improve postoperative analgesia and early rehabilitation after total knee arthroplasty? A prospective, randomized, double-blinded study.
The aim of this prospective, randomized, double-blind study was to evaluate whether continuous sciatic nerve block can improve postoperative pain relief and early rehabilitation compared with single-injection sciatic nerve block in patients undergoing total knee arthroplasty (TKA) and lumbar plexus block. ⋯ Continuous sciatic nerve block improves analgesia, decreases morphine request, and improves early rehabilitation compared with single-injection sciatic nerve block in patients undergoing TKA and lumbar plexus block.
