[Spinal anesthesia in ambulatory anesthesia of the infant]

Two hundred spinal anesthesias have been performed in infants for abdominal surgery, thirty of which for day surgery. Intrathecal injection of 0.5% bupivacaine solution is realised in good conditions, sometimes with narcosis complementation (ketamine or halothane). Motor block takes place without delay and lasts for an average of 95 +/- 25 minutes. There is no hemodynamic disturbance. This technic could be used in day surgery by reason of quick recovery.
