Readiness of Discharge

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.
