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.

Official Title: | Intravenous Versus Caudal Supplementation of Ketamine for Postoperative Pain Control in Children,A Double-Blind Controlled Clinical Trial. |
Estimated Enrollment: | 40 |
Study Start Date: | November 2007 |
Estimated Study Completion Date: | July 2009 |

Arms | Assigned Interventions |

1: Experimental
epidural s(+)-ketamine for supplementation of caudal anesthesia
|
Drug: S(+)-ketamine
epidural or intravenous 1 mg kg-1 once concurrent with caudal anesthesia
|
2: Active Comparator
intravenous ketamine for supplementation of caudal anesthesia
|
Drug: S(+)-ketamine
epidural or intravenous 1 mg kg-1 once concurrent with caudal anesthesia
|
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.
