Abstract

This retrospective study assessed the effectiveness and side effects of conscious sedation using chloral hydrate, hydroxyzine, and N2O/O2 in the sedation of 149 pediatric patients over 188 sedation sessions, and to identify associated variables. The effectiveness of the sedation was evaluated using the Houpt scale, and was considered effective for scale categories of excellent or good. Effectiveness and side effects were assessed every 15 minutes. The effectiveness decreased and side effects increased over time. The effectiveness of sedation during 60 minutes was 57.4%, and one or more side effects occurred in 18.1% of sessions. Effectiveness of sedation increased with body mass index (BMI). When patients were sedated at the beginning of the procedure, the effectiveness was greater. Side effects increased with patient age. When sedation was divided into two sessions, the number of sedation did not affect the effectiveness or side effects. It can be suggested that sedation should be performed over two separate sessions, as a single prolonged session may lead to reduced effectiveness and increased side effects. To maximize effectiveness and minimize side effects, several variables such as BMI, whether to sedate at the beginning of the procedure and age should be considered thoroughly before sedation.

이 후향적 연구는 chloral hydrate, hydroxyzine 및 N2O/O2 조합을 이용한 진정 치료를 시행한 149명 환아의 188회 진정 치료의 효과와 부작용에 대해 알아보고, 효과와 부작용에 영향을 미칠 수 있는 요소를 확인하고자 하였다. 진정 치료의 효과는 Houpt 분류법을 이용하여 측정하였고, excellent와 good의 경우 효과적으로 분류하였다. 진정 치료 시간을 15분 간격으로 나누어 효과와 부작용을 분석한 결과, 치료 시간이 증가할수록 효과는 감소하고 부작용은 증가하는 것으로 나타났다. 60분 동안의 진정 치료 효과는 57.4% 이었으며, 전체 부작용 발생률은 18.1%이었다. 진정 치료의 효과는 Body mass index(BMI)가 증가할수록 증가하였으며, 술식 시작 시 진정이 되어있는 경우 진정 치료 효과가 높은 것으로 나타났다. 부작용은 나이가 증가할수록 증가하였다. 진정 치료가 2회로 나누어 시행되었을 때, 진정 치료의 횟수는 효과와 부작용에 영향을 미치지 않았다. 진정 치료 시간을 무리하게 연장하는 것은 효과 감소와 부작용 증가를 불러일으킬 수 있으므로 진정 치료를 2회에 나누어 시행하는 것이 필요할 것으로 생각된다. 또한 BMI, 술식 시작 시 진정 여부 및 나이와 같은 진정 효과를 감소시키고 부작용을 증가시키는 요소에 대한 충분한 고려가 선행된 후 진정 치료를 시행하여야 할 것으로 생각된다.
