Effect of Ketamine-Sufentanil and Ketamine-Midazolam to induce sedation and analgesia in Pediatric with Lumbar Puncture or Bone Marrow Aspiration

The combination of sedative and analgesic drugs has a favorable effect on pain management and sedation during painful procedures in pediatrics. Therefore, our aim was to compare the effect of sedation and analgesia of ketamine-sufentanil and ketamine-midazolam in painful procedures in children with blood malignancies.
This double-blind, clinical trial was performed on 82 children with malignancy who had indication of painful diagnostic intervention; patients were randomly divided into two groups of ketamine-sufentanil (KS) and ketamine -midazolam (KM).
In KS group, sufentanil 0.5mcg/ kg and ketamine 1mg/ kg and in the KM group, ketamine 1mg/ kg, and midazolam 0.1mg/ kg bolus were prescribed. In either group, hemodynamic indicators of sedation, side effects, duration of effectiveness were recorded. Data were analyzed using SPSS 20.
Sedation based on Ramsay sedation score was not significantly different between the two groups (p= 0.39). The average recovery time in the midazolam-ketamine group was higher (p-value= 0.076).
The combination of ketamine-sufentanil and ketamine-midazolam was effective in sedation and analgesia in bone marrow aspiration and lumber puncture; side effects were however, lower in ketamine-midazolam group.
