[Spinal anaesthesia in day case surgery--Old technique--new trends].

Day case surgery is becoming more and more important. In order to perform these services cost-efficiently it is of primary importance to ensure that procedures can be scheduled with the largest possible patient satisfaction. Up to now spinal anaesthesia was of little importance in day case surgery due to prolonged nerve block and negative side effects especially when using long acting local anaesthetics. Since prilocaine and 2-chloroprocaine, two short acting local anaesthetics with a known low incidence of side effects, were recently introduced into clinical practice a reevaluation of spinal anaesthesia in a day case setting according to EMB guidelines still has to be done.
