Preemptive analgesia can improve postoperative pain management. Ketamine may prevent central sensitization during surgery and result in preemptive analgesia. The purpose of this study is to examine the effectiveness of ketamine as a preemptive analgesic as previous studies have shown the involvement of N-methyl-D-Aspartate (NMDA) receptor in neuroplasticity.

Condition Intervention Phase

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Care Provider)

Primary Outcome Measures:
  • pain score [ Time Frame: 24 hours after anesthesia ]

Secondary Outcome Measures:
  • analgesic request [ Time Frame: 24 hours after anesthesia ]

Estimated Enrollment: 40
Study Start Date: November 2007
Estimated Study Completion Date: July 2009
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
epidural s(+)-ketamine for supplementation of caudal anesthesia
Drug: S(+)-ketamine
epidural or intravenous 1 mg kg-1 once concurrent with caudal anesthesia
Active Comparator: 2
intravenous ketamine for supplementation of caudal anesthesia
Drug: S(+)-ketamine
epidural or intravenous 1 mg kg-1 once concurrent with caudal anesthesia

Detailed Description:
After receiving consent inform from parents, 40 children scheduled for orthopedic surgeries will be randomized to one of two groups: epidural group and intravenous group, both will receive 1 mg kg-1 S(+)-ketamine. All patients will receive caudal block anesthesia with marcaine. Cardiovascular monitoring will be assessed during operation. Follow up will continue for 24 hours after caudal block. Duration of analgesia, first time of analgesic request and complications will be recorded by an orthopedic assistant that is blinded to study. Data will be analyzed statistically by Chi square, t test and nonparametric tests.
