Randomized Controlled Trial Comparative Study Clinical TrialComparison between hemodynamic changes after single-dose and incremental subarachnoid anesthesia.
The depressant activity on sympathetic tone of subarachnoid anesthetic block is well known. The aim of this study was to compare cardiovascular response to an incremental dose of subarachnoid anesthesia administered through a small-bore microcatheter with the response to single-dose spinal anesthesia. ⋯ In well-hydrated, healthy patients incremental local anesthetics offer adequate subarachnoid anesthesia with minimal hemodynamic effects.

Case ReportsPressure sores as a complication of patient-controlled epidural analgesia after cesarean delivery. Case report.
Postoperative epidural analgesia using mixtures of bupivacaine and opioids has become common practice following abdominal surgery. Side effects such as hypotension, motor block, respiratory depression, pruritus, and urinary retention are well known. Pressure sores occurring within the first 24 hours are extremely rare. ⋯ Pressure sores following postoperative epidural analgesia may occur even in young patients. Although bupivacaine may induce a motor block, its combination with other drugs in the analgesic mixture or other contributing factors may explain the occurrence of pressure sores. Prophylaxis and increased alertness should eliminate this complication.
