Variations in Physiological, Psychomotor, and Analgesic Parameters during Titration of Nitrous Oxide in 3-12 Years Old Children Managed with Inhalation Sedation.

BACKGROUND

The present study was designed to assess variations in physiological, psychomotor parameters, and analgesic effects at various levels of nitrous oxide-oxygen analgesia in 3-12 years old children.

DESIGN

One hundred children aged 3-12 years were assessed for physiological, psychomotor, and analgesic parameters at various concentrations of NO, i.e., baseline, 20, 40, 50, and 0% (100% O). Physiological, psychomotor, and analgesic effects were assessed using a pulse oximeter, bender visual-motor Gestalt test, and response to electric pulp tester, respectively.

RESULTS

Oxygen saturation (SpO) showed a significant increase while heart rate (HR) showed a significant reduction at 50% NO. No significant changes were observed in respiratory rate with a change in NO levels. Significant reduction in the pain scores was found at the same level of stimulation by an electric pulp tester at 40 and 50% levels. The psychomotor changes were consistently higher at every concentration of nitrous oxide. However, no correlation could be found between various parameters tested.

CONCLUSION

NO caused a significant increase in SpO in both the age groups, a decrease in HR, a significant decrease in pain score at 40 and 50% concentration of NO, and had a significant effect on the psychomotor ability of children.
