The purpose of this study is to determine whether ketamine, midazolam, and meperidine are more effective than midazolam and meperidine alone for procedural sedation and analgesia in pediatric digestive endoscopy. Secondary outcomes are the incidence of cardiorespiratory side effects and the necessity of rescue doses.

Further study details as provided by Université de Montréal:

Primary Outcome Measures:
  • pain score [ Time Frame: after one year ] [ Designated as safety issue: No ]
    pain scores are accorded at the end of each endoscopy. Pain scores of the two groups will be compared after one year

Secondary Outcome Measures:
  • necessity of cardiopulmonary intervention (Oxygen requirements) [ Time Frame: after one year ] [ Designated as safety issue: Yes ]
    according to Observer'sAssessment of Alertness/Sedation (OAAS) score

Estimated Enrollment: 90
Study Start Date: July 2010
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ketamine
group with triple sedation (ketamine, midazolam, meperidine)
Drug: ketamine
0.5mg/kg ketamine iv
Other Name: no other names
Placebo Comparator: placebo
group with conventional sedation and placebo ( midazolam, meperidine and placebo)
Drug: ketamine
0.5mg/kg ketamine iv
Other Name: no other names

Detailed Description:

90 patients will be included. The sedation will include 0.1mg/kg, max 5mg iv of midazolam, 1mg/kg, max 50mg iv of meperidine, and placebo (0.9%NaCl) or ketamine 0.5mg/kg iv. Rescue doses will be given as usual, using meperidine and or midazolam 50% of the initial dose.
