A patient undergoing knee arthroscopy under spinal anaesthesia as a day case received intrathecal bupivacaine. Discharge from hospital requires resolution of which specific block-related milestone?
- A Full regression of motor block and ability to walk without assistance ✓
- B Return of proprioception at the ankle
- C Complete return of sympathetic tone confirmed by normal pupil size
- D Passing flatus spontaneously
Correct answer: A. Full regression of motor block and ability to walk without assistance
Explanation
After neuraxial anaesthesia, day-case discharge criteria include full motor recovery, intact sensation, and the ability to ambulate without assistance, reflecting resolution of the block. Proprioception and pupillary signs are not standard milestones, and flatus relates to return of gut function relevant after abdominal surgery or general anaesthesia rather than to spinal block resolution. Voiding is also required if bladder function was affected.
