Premedicación con clonidina y ketamina intraoperatoria a bajas dosis en la colecistectomía laparoscópica ambulatoria

Patients receiving clonidine and ketamine required less additional opiate analgesia to achieve mild pain values ( < 3 on the numerical verbal scale) but suffered more adverse effects during their stay in the postanesthesia recovery unit. Discharge was not delayed, however.
