About this trial
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.

quality of recovery
using QOR-15 score; 15-item questionnaire designed to assess a patient's quality of recovery following surgery and anesthesia It measures recovery across five key domains: physical comfort, pain, physical independence, psychological support, and emotional state. Scoring Range: Each of the 15 questions is rated on an 11-point scale (0-10). The total score ranges from 0 (extremely poor recovery) to 150 (excellent recovery).
