Escalating Ketamine Doses and Pre-emption

February 16, 2010 updated by: Tel-Aviv Sourasky Medical Center

EARLY PREOPERATIVE ESCALATING DOSES OF KETAMINE ATTENUATE POSTOPERATIVE PAIN AND REDUCE MORPHINE CONSUMPTION IN HUMANS

Ketamine affects postoperative pain when administered intravenously immediately before, during or at the end of surgical procedures. We assessed the effects of multiple and escalating doses of ketamine administered many hours before surgery on postoperative pain and analgesia consumption.
