Beyond strict selection of suitable patients the adequate choice of th
e best moment for discharge home is essential for safety and efficacy
of outpatient surgery. Restitution of cardiovascular stability and psy
chomotoric function is completed at the end of observation in the reco
very unit. Further prerequisites of home discharge are absence of post
operative nausea and vomitus as well as sufficient pain control by non
-opioids and physical measures. The definition of fixed observation pe
riods is unreasonable, technical examinations and psychomotoric tests
are of minor importance. Home readiness has to be evaluated by a physi
cian before discharge. Standardized scores or checklists may be of som
e help. The modalities of patient care after discharge are checked pri
or to surgery. During late postoperative recovery, continuous care of
a responsible adult is required for at least 24 hours. During this tim
e period certains restrictions must be respected, e.g. from driving an
d business contracts. Even after this time some residual effects of an
esthesia may still be present.
