Ketamine Has No Pre-emptive Analgesic Effect in Children Undergoing Inguinal Hernia Repair

Previous studies have suggested that ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, provides a pre-emptive analgesic effect and pre-emptive analgesia improves postoperative pain management. The aim of this study was to determine the effict of pre-incisional vs. post-incisional intravenous low dose of racemic ketamine in postoperative pain in children undergoing inguinal hernia re...

Lack of a pre-emptive effect of low-dose ketamine on postoperative pain following oral surgery.

PURPOSE The aim of this study was to assess the effect of pre- vs postincisional low-dose iv ketamine on postoperative pain in outpatients scheduled for oral surgery under general anesthesia. METHODS Eighty-four patients were randomly assigned to receive intravenously saline before and after surgery in Group 1, ketamine 300 microg x kg(-1) iv before and saline after surgery in Group 2, saline...

Pre-emptive analgesia.

Transmission of pain signals evoked by tissue damage leads to sensitization of the peripheral and central pain pathways. Pre-emptive analgesia is a treatment that is initiated before the surgical procedure in order to reduce this sensitization. Owing to this 'protective' effect on the nociceptive system, pre-emptive analgesia has the potential to be more effective than a similar analgesic treat...

Effect of pre-emptive ketamine on sensory changes and postoperative pain after thoracotomy: comparison of epidural and intramuscular routes.

BACKGROUND In this study we have evaluated the efficacy of ketamine via i.m. and epidural routes for the control of post-thoracotomy pain. METHODS The study was randomized, double blinded and placebo controlled. With the approval of the Faculty Ethics Committee, 60 patients undergoing elective thoracotomy were randomized into three equal groups. Group IM had i.m. ketamine 1 mg kg(-1) in 2 ml ...
