본 연구의 목적은 소아 환자의 치과 진료를 위한 진정요법 시 chloral hydrate와 hydroxyzine의 경구 투여와 midazolam과 meperidine의 경구 투여간의 임상적인 진정효과 및 합병증 발생 여부를 비교하는 것이다. 삼성서울병원 소아치과를 내원한 환아 중 ASA I 또는 II에 해당하는 4세 미만의 아동 15명을 대상으로 하여 한 달여 간격으로 두 차례에 걸친 진정요법을 시행하였다. 2회의 진정요법 중 1회는 chloral hydrate (60mg/kg)/hydroxyzine(25mg)을 경구 투여하고 나머지 1회는 midazolam(1mg/kg)/meperidine(1mg/kg)을 경구 투여하였으며 투여 순서는 무작위로 정하였다. 두 차례 모두 $N_2O-O_2$ 흡입진정을 병용하였다. 각 치료과정에 따른 진정효과는 Houpt Scale(수면, 움직임, 울음, 전반적인 행동 지수)로 측정하였고 pulse oximeter를 이용하여 저산소증의 유무를 비교, 평가하고 약물 투여 후 구토의 여부를 함께 평가하여 다음과 같은 결과를 얻었다. Chloral hydrate와 hydroxyzine을 경구 투여한 군이 midazolam과 meperidine을 경구 투여한 군보다 전반적인 행동 지수에서 통계학적으로 유의하게 우수한 결과를 보였으며 어느 군에서도 저산소증은 보이지 않았다. 본 연구에서는 chloral hydrate와 hydroxyzine의 경구 투여가 midazolam과 meperidine의 경구 투여보다 우수한 진정효과를 보이는 것으로 판단된다.

Purpose: We aimed to analyze the effectiveness and safety of low-dose midazolam and ketamine combination for upper gastrointestinal endoscopy (UGIE) in children. Methods: The study included the children (n=425, $10.78{\pm}3.81years$) who underwent UGIE for diagnostic purpose during 1 year period. All children were sedated with low dose midazolam (0.1 mg/kg) and ketamine (0.5 mg/kg) intravenously. Effectiveness of the sedation and complications during the procedure and recovery period were recorded. Results: Endoscopic procedure was successfully completed in 414 patients (97.4%; 95% confidence interval, 95.8-98.9). $Mean{\pm}standard$ deviation (SD) duration of procedure was $6.36{\pm}1.64minutes$ (median, 6.0 minutes; range, 4-12 minutes). Minor complications occurred during the procedure in 39.2% of the patients. The most common complication was increased oral secretion (33.1%). No major complications were observed in any patient. Age and Ramsay sedation scores of patients with complications during the procedure were lower than the others ($9.49{\pm}4.05years$ vs. $11.61{\pm}3.43years$, p=0.002 and $2.10{\pm}1.46$ vs. $4.37{\pm}1.16$, p=0.001). Mean recovery time was 22 minutes (range, 10-90 minutes; $mean{\pm}SD$, $25{\pm}12.32minutes$). Minor complications developed during recovery in 60.1% of the patients. The most common complication was transient double vision (n=127, 30.7%). Emergence reaction was observed in 5 patients (1.2%). Conclusion: The procedure was completed with high level of success without any major complication in our study. Combination of low-dose midazolam and ketamine is a suitable sedation protocol for pediatric endoscopists in UGIE.

Background/Aims: Data on the incidence of adverse respiratory events during recovery from gastrointestinal endoscopy are limited. The aim of this study was to investigate the incidence of these complications. Methods: In this retrospective cohort study, data were obtained from the electronic records of 657 consecutive patients, who underwent gastroenterological procedures under sedation. Results: Pulse oximetry oxygen saturation (SpO₂) <90% for <60 seconds occurred in 82 patients (12.5%), and in 11 patients (1.7%), SpO₂ of <90% for >60 seconds occurred in 79 patients (12.0%) and in 14 patients (2.1%), and SpO₂ <75% occurred in four patients (0.6%) and in no patients during the procedure and recovery period, respectively. No major complications were noted. The occurrence of desaturation during recovery was correlated with desaturation during the procedure (p<0.001). Higher American Society of Anesthesiologists score (odds ratio [OR], 1.867; 95% confidence interval [CI], 1.008-3.458), ischemic heart disease (OR, 1.815; 95% CI, 0.649-5.080), hypertension (OR, 1.289; 95% CI, 0.472-3.516), and diabetes mellitus (OR, 2.406; 95% CI, 0.950-6.095) increased the occurrence of desaturation during recovery. Conclusions: We found no major complications during recovery after balanced propofol-based sedation administered by a gastroenterologist-nurse team. Patients with the identified risk predictors must be monitored carefully.

Background/Aims: The efficacy of propofol in gastrointestinal endoscopy for patients with midazolam-induced paradoxical reactions remains unclarified. This study aimed to compare the efficacy and safety of propofol-based sedation in patients who previously experienced paradoxical reactions. Methods: This was a prospective, single-blinded, randomized controlled pilot study. Participants with a history of paradoxical reactions to midazolam during a previous esophagogastroduodenoscopy were recruited and randomly assigned to group I (propofol monosedation) or group II (combination of propofol and midazolam). The primary endpoint was the occurrence of a paradoxical reaction. Results: A total of 30 participants (mean age, 54.7±12.6 years; male, 19/30) were randomly assigned to group I (n=16) or group II (n=14). There were no paradoxical reactions in group I, but there were two in group II, without a significant difference (p=0.209). The mean dose of propofol was higher in group I than in group II (p=0.002). Meanwhile, the procedure and recovery times did not differ between groups. Conclusions: Propofol-based sedation was safe and effective for patients who experienced paradoxical reactions to midazolam. However, caution is needed because few cases of paradoxical reaction again can happen in group II in which midazolam was readministered.

Background: The purpose of this study was to compare the use of midazolam only with midazolam with fentanyl or propofol in IV sedation. Methods: 24 cases were divided to midazolam group (M group), midazolam + fentanyl group (MF group), midazolam + propofol group (MP group) and midazolam + fentanyl + propofol group (MFP group). In M group, 2 ml midazolam was injected at first, than at 2 minutes interval 1-2 ml injected continuously depending on the level of sedation. In MP, MFP groups, propofol was injected at the speed of 15-20 ml/hr by infusion pump. In this study, the sedation level was evaluated by using OAA/S scale. In each groups, the recovery time was measured until OAA/S scale score level was 5, and pre and postoperative blood pressure change was measured. Each group's data was statistically analyzed using one-way ANOVA. If significant statistical difference were observed, Dunnet test was performed, and control group was M group. Results: Pre and postoperative blood pressure change were not represent significant statistical difference in 4 groups (P value = 0.679 [systolic], P value = 0.206 [diastolic]). But recovery time were represent significant statistical difference (M group: 35.6, MF group: 32.5, MP group: 17.9, MFP group: 19.6 [P value = 0.002]). The result of Dunnet test on recovery time showed significant statistical difference on MF, MFP group when M group was control group. In MFP group, sedation was increased by using supplemental fentanyl, and postoperative pain control was dominant. Conclusion: To achieve the effect of anxiolysis, analgesia, amnesia effectively, and short recovery time, MFP group is mostly recommended.

목 적: 상부위장관 내시경은 위장관계 질환을 검사하는 데 매우 유용한 검사이나, 소아에서는 검사에 따른 불안과 불편감으로 시행에 어려움이 많다. 최근에 midazolam 등의 진정제 투여로 이런 것들을 상당부분 개선하고 있다. 저자들은 midazolam 투여시 소아의 활력징후 변화를 측정하여 약제투여의 안전성과 진정 효과를 확인하고자 하였다. 방 법: 2003년 8월부터 2005년 7월까지 연세대학교 의과대학 소아과에 내원하여 상부위장관 내시경 검사를 받은 244명의 소아를 대상으로 midazolam 투여군과 비투여군에서 검사 전과 검사 도중의 산소포화도, 심박동수, 의식상태의 변화 등을 측정하여 그 결과를 조사 분석하였다. 결 과: midazolam 투여군과 비투여군 사이에 생명 활력 징후는 임상적으로 유의한 차이가 없었다. 내시경검사 시 투여된 midazolam의 용량과 의식상태 및 산소포화도 변화사이에 유의한 상관관계는 없었다. 산소포화도는 비투여 및 투여군 양 군에서 검사 전보다 검사 도중에 유의하게 감소하였으나(p<0.01), 양 군 모두에서 산소포화도는 95% 이상으로 유지되어 임상적 의미는 없었다. 심박동수는 비투여 및 투여군 모두에서 검사 전보다 검사 도중이 유의하게 증가되었으나(p<0.01), 양 군 간의 심박동수 증가는 통계학적으로 유의한 차이는 없었다. 투여 용량의 증량에도 진정효과가 더 잘 유도되지 못했으며 대부분의 환아가(76.1%) alert한 의식상태를 유지하여 진정효과가 충분하지 못하였다. 결 론: 본 연구에서 저용량 midazolam을 투여하였을 때 생명활력징후의 안전성은 확인하였으나, 충분한 진정효과 및 기억 상실 효과를 얻기에는 다소 미흡하였다.

Purpose: This retrospective study assessed the effectiveness of submucosal (SM) midazolam (M), oral chloral hydrate (CH), hydroxyzine (H), and nitrous oxide (N) 99 uncooperative pediatric dental patients over 182 sedation sessions. Methods: Selection criteria included good medical health (ASA I), from 2 to 6 years of age, uncooperative behavior, and the need for restorations and dental surgery. The children who was administerated with CH H, N was Group 1 (48 case). The children who was administerated with CH, H, N, M was Group 2 (51 case). All the patients received oral CH (50-70 mg/Kg), H (1 mg/Kg) and N (less than 50%). Additionally the Group 2 received SM midazolam (0.1-0.2 mg/kg). Behavior response was rated as quiet (Q), crying (C), movement (M), or struggling (S) every 5 minutes through operative procedures. Behavior response rating was assigned to Houpt scale of Overall behavior. Data was analyzed using Chi-Square Test. Results: The Group 2 had more effective (88.2%) than the Group 1 (68.8%)(P = 0.05). Also, vomiting response decreased in the Group 2 (94.4%) than those with oral administration of chloral hydrate alone without SM midazolam (77.1%)(P = 0.05). Conclusions: SM midazolam improved the quality of sedation and vomiting response.
