Background: The aim of this study was to examine the difference of $SpO_2$, PR, $EtCO_2$, RR with submucosal injection of midazolam to oral chloral hydrate and hydroxyzine for pediatric patients Methods: Thirty two sedation cases were performed in this study. Patients were randomly classified into one group taking oral CH (60 mg/kg). hydroxyzine (1 mg/kg) and submucosal injection of midazolam (0.1 mg/kg) and the other group recieving oral CH (50 mg/kg), hydroxyzine (1 mg/kg) and submucosal injection of midazolam (0.2 mg/kg). For evaluating the depth of sedation. data including saturation percentage of oxygen ($SpO_2$), pulse rate (PR), end-tidal carbon dioxide ($EtCO_2$), respiratory rate (RR) and the behavior scale were checked every 2 minutes and were collected for only 40 minutes from the beginning of treatment and were analyzed using Two independent sample T-test. Results: Analysis showed no significant difference in the mean $SpO_2$, PR, $EtCO_2$, RR during sedation between two groups (P > 0.05). The values of $SpO_2$, PR, $EtCO_2$ and RR for both groups remained within the normal values. Conclusions: The results of this present study indicate that combination of oral CH, hydroxyzine, nitrous oxide gas inhalation and submucosal injection of midazolam improved the sedation quality without compromising safety.
