Abstract

Purpose. The objective of this study was to evaluate the behavioral response and assess the effectiveness of additional intranasal (IN) and submucosal (SM) administration of midazolam during pediatric sedation for dental procedure. Material and methods. Thirty-three cases of healthy (ASAⅠ), uncooperative children aged from 24 to 72 month old at pediatric dental clinic of Ewha Womans University Hospital were selected for this study. Children received oral chloral hydrate 50 mg/kg with hydroxyzine 1.0 mg/kg. After waiting for 45 minutes, midazolam 0.2 mg/kg was administrated via IN route and via SM route randomly maintaining 50% of $N_2O$. A pulse oximeter and a capnograph were used for measuring vital signs ($SpO_2$, PR, RR, $EtCO_2$) throughout the sedation. Behavioral response was evaluated as Quiet (Q), Crying (C), Movement (M) or Struggling (S) in every 2 minutes for 40 minutes. Results. There were also no statistically significant differences in vital signs of the two groups. The behavioral response for the first ten minutes during sedation was a statistically significant difference (P < 0.05) between the two groups. After the first ten minutes, it was revealed that there was no significant difference. Conclusion. This study demonstrated that the addition of IN midazolam to the combination of oral chloral hydrate with hydroxyzine and nitrous oxide/oxygen inhalation is as safe and effective as that of SM midazolam in pediatric sedation for dental procedure.

진정법을 이용한 소아환자의 치과치료 시 chloral hydrate와 hydroxyzine을 복용 후 추가로 midazolam을 비점막내로 분무하는 것과 구강 점막 하로 주사했을 때 행동 반응과 진정 효과에 대해 비교하고자 하였다. 미국 마취과학회 신체등급 I급 (ASAI)이며, 협조가 안 되는 24-72 개월 소아 환자 중 진정법을 통해 2개 치아 이상의 보존 치료 및 발치 치료를 받은 33명을 대상으로 하였다. 모든 환자는 chloral hydrate 50 mg/kg 와 hydroxyzine 1 mg/kg 복용하였다. 45분 후 한 군은 비강내로 midazolam 0.2 mg/kg 을 추가 투여하였고 다른 군은 구강 점막 하 midazolam 0.2mg/kg 을 주사하였다. 치료하는 동안 두 군 모두 50 % nitrous oxide 를 유지하였다. 맥박 산소 계측기와 호기말 이산화탄소 분압 측정기를 이용하여 산소 포화도, 맥박수, 호흡수, 호기말 이산화탄소 분압을 기록하였다. 행동 반응은 Quiet(Q), Crying(C), Movement(M) 그리고 Struggling(S)를 이용하여 총 40분 동안 매 2분마다 기록하고 모든 진정 치료 과정은 비디오로 촬영하였다. 모든 자료는 chi-sqaure test와 two sample independent t-test를 사용하여 분석하였다. 두 군간의 평균 도입 시간과 최대 치료 시간은 통계학적으로 유의한 차이가 없었다. 또한 활력 생징후도 모두 정상 범위이며 두 군 사이에 통계학적으로 유의한 차이가 없었다. 행동 반응 비교에서는 치료 시작 10분 동안 비강내 투여 군이 점막 하 투여 군보다 개선된 행동 반응을 보였다(P<0.05). 치료 시작 10분 이후에는 두 군사이의 행동 반응에서 유의한 차이가 없었다. 이 연구는 chloral hydrate 와 hydroxyzine 복용 후 nitrous oxide 50%로 유지하는 진정법에 비강내로 midazolam을 추가 투여하는 것은 점막 하로 추가 투여와 유사한 진정 효과를 가진다. 또한 비강내 midazolam 추가 투여하는 것은 구강 점막 하로 추가 투여의 장점을 가지면서도 비침습적이고 상대적으로 통증이 적다는 이점이 있다. 그러므로 비강내 midazolam 추가 투여는 침습적인 구강 점막 하 추가 투여를 대체할 만한 방법이다.
