简要总结
Most minor perianal surgeries are performed as day-case procedures requiring rapid recovery and effective symptom control. Saddle block anesthesia (SBA) provides reliable perineal anesthesia with minimal hemodynamic and motor effects, promoting faster recovery than general anesthesia. However, the duration of sitting after intrathecal injection influences anesthetic spread, and the optimal sitting time to balance adequate anesthesia with early discharge remains unclear.
详细描述
Spinal anesthesia will be administered in the sitting position at the L4-5 interspinous space using 7.5 mg of 0.5% hyperbaric bupivacaine.
Hemodynamic data (heart rate and blood pressure) will be recorded at baseline, then at 2 min interval after SBA until the end of surgery.
Postoperative pain will be assessed using the numeric rating scale at the post anesthesia care unit (PACU) and before discharge. If the numeric rating scale (NRS) > 3 or at any time if demanded by the patient, 15 mg of IV ketorolac will be given if persisted titrated doses of nalbuphine will be given In case of postoperative nausea and vomiting, 4 mg of IV ondansetron will be given.
