ABSTRACT

Aim

The need to manage children using safe, effective and inexpensive conscious sedation materials and techniques in
paediatric dentistry is high. This study evaluated the safety and effectiveness of a combination of low dose ketamine (5 mg/kg) and
diazepam (0.2 mg/kg) used for conscious sedation in healthy children undergoing paediatric dental procedures at a paediatric dental
outpatient clinic over a 3-year period.

Methods

All children who were scheduled for conscious sedation between
2009 and 2012 were included in the study. All children received ketamine 5 mg/kg body weight in combination with diazepam 0.2 mg/kg
body weight in a single oral dose for use as conscious sedation. Patients were considered sedated when the Ramsey Score was 2 or 3.
Time of onset and duration of surgical procedures were recorded. Side effects during and after discharge were recorded.

Results

Twenty five patients participated in the study. The effectiveness of the sedation was 84.0. The mean time of onset of action was
10.5 7.2 minutes. All cases that needed additional sedation needed this after 35?36 minutes. Three cases (12.0)
developed high temperature in the night of the day of the procedure. There was a case (4.0) of hallucination.

Conclusion

Ketamine and diazepam as medication for conscious sedation was considered effective. The duration of effectiveness appears to be 35
minutes. The combination is considered safe for use for conscious sedation in healthy paediatric dental outpatients undergoing minor
oral surgical procedures.
