Purpose: Gastrointestinal (GI) endoscopy is an important tool for diagnosing and treating GI diseases in children. This study aimed to analyze the current GI endoscopy practice patterns among South Korean pediatric endoscopists. Methods: Twelve members of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition developed a questionnaire. The questionnaire was emailed to pediatric gastroenterologists attending general and tertiary hospitals in South Korea. Results: The response rate was 86.7% (52/60), and 49 of the respondents (94.2%) were currently performing endoscopy. All respondents were performing esophagogastroduodenoscopy, and 43 (87.8%) were performing colonoscopy. Relatively rare procedures for children, such as double-balloon enteroscopy (DBE) (4.1%), endoscopic retrograde cholangiopancreatography (ERCP) (2.0%), and endoscopic ultrasound (EUS) (2.0%), were only performed by pediatric gastroenterologists at very few centers, but were performed by adult endoscopists in most of the centers; of all the respondents, 83.7% (41/49) performed emergency endoscopy. In most centers, the majority of the endoscopies were performed under sedation, with midazolam (100.0%) and ketamine (67.3%) as the most frequently used sedatives. Conclusion: While most pediatric GI endoscopists perform common GI endoscopic procedures, rare procedures, such as DBE, ERCP, and EUS, are only performed by pediatric gastroenterologists at very few centers, and by adult GI endoscopists at most of the centers. For such rare procedures, close communication and cooperation with adult GI endoscopists are required.

Background: Anxiety and fear in children's dental care are major impediments to successful dental care. High-quality dental treatment can be achieved using various behavioral control methods; however, conscious sedation using drugs can be used if behavioral control is difficult, owing to excessive fear and anxiety. This study aimed to examine the trends in conscious sedation implemented in pediatric dentistry at the Dankook University Dental Hospital over the past 11 years. Methods: This study included 6,438 cases of dental treatment under conscious sedation conducted over 11 years between January 2011 and December 2021 in the Department of Pediatric Dentistry at Dankook University Dental Hospital. Results: Over the past 11 years, the number of dental treatments under sedation has increased. In the case of inhalation sedation using nitrous oxide, the rate of increase was approximately twice every year, and the use of midazolam gradually decreased. The average age of children who underwent sedation was 5.11 years, and the rate of sedation treatment in children aged <4 years tended to decrease, while that of children aged >5 years tended to increase. This is related to the trend of changes in drugs used. In a sex-based survey, sedation treatment rate was higher in males than that in females. Conclusion: Appropriate selection of sedatives can reduce the frequency of general anesthesia and minimize complications through efficient and safe dental treatments. Trend analysis of sedation by year will help provide guidelines for the appropriate selection of sedation for dental treatment of children and patients with disability.

목 적 : 식도 이물의 내시경적 적출의 최근 경향과 내시경적 적출의 유용성에 대해 알아보고 소아에서 유연형 내시경을 통한 식도 이물 제거술이 정착되기를 바라는 마음으로 이 연구를 시작하였다. 방 법 : 1987년 1월부터 2001년 7월까지 14년 6개월간 경상대학교병원 소아과와 이비인후과에서 식도 이물로 진단하여 유연형 내시경과 강직형 내시경으로 치료하였던 127례를 대상으로 하였다. 유연형 내시경의 경우는 소아과에서 Olympus사의 XP-20, XQ-240과 Pentax사의 2731와 다양한 보조 기구를 사용하고 전신마취나 midazolam이나 diazepam 등의 약제는 사용하지 않았다. 결 과 : 1) 연도별 분포 : 1998년까지는 이물의 제거에 강직형 내시경이나 유연형 내시경이 비슷하게 이용되어 왔다. 1999년 이후부터 유연형 내시경에 의한 이물의 제거가 활발히 이루어졌다. 2) 연령별, 성별 분포 : 유연형 내시경을 사용한 경우는 1세 미만의 경우 4례(6%)였고, 1-5세의 경우 43례(65.1%), 5-10세의 경우 17례(25.7%), 10-15세의 경우 2례(3.2 %)로 총 66례였다. 강직형 내시경을 사용한 경우는 1세 미만의 경우 8례(13.5%), 1-5세는 42례(68.8%), 5-10세는 7례(11.5%), 10-15세는 4례(6.6%)로 총 61례였다. 두 경우 모두 1-5세가 호발 연령이었다. 남녀 비를 보면 유연형 내시경을 사용한 경우 1.64 : 1이었고 강직형 내시경을 사용한 경우에는 1.13:1로 남아에서 다소 많았다. 3) 이물의 종류, 증상, 제거까지 걸린 시간 및 합병증 : 이물의 종류로는 유연형 내시경으로 제거한 경우는 54례, 강직형 내시경으로 제거한 경우 42례로 동전이 제일 많았고 임상 증상은 유연형 내시경의 경우에는 무증상이, 강직형 내시경의 경우에는 연하 곤란이 제일 많았다. 식도 이물을 제거까지 걸린 시간은 대부분 이물을 삼킨 후 24시간 이내였다(108례, 85%). 24시간 이후에 이물을 제거 한 경우는 병원에 늦게 온 경우이며 17례(5%)였다. 이중 합병증이 발생한 경우는 11례로 미란이 7례, 궤양소견을 보인 1례, 출혈 2례, 천공 소견을 보인 1례가 있었다. 4) 동반 질환 : 동반된 질환아 있었던 8례(7.5%)였으며 식도 협착이 5례, 뇌성 마비가 3례였다. 결 론 : 본 병원에 소아 내시경실이 생긴 이후 과거 10년 동안 소아 내시경에 의한 이물의 제거가 많이 이루어졌지만 뚜렷한 이점을 발견 할 수 없었던 강직형 내시경을 이용한 이물의 제거가 최근 2-3년 전까지도 활발히 이루어져 왔다는 것을 알 수 있었다. 유연형 내시경은 전신 마취의 불편함 없이도 쉽게 할 수 있는 안전하고 효과적인 방법이며, 최근 2-3년 간 유연형 내시경에 의한 식도 이물의 제거가 빈번해졌다. 앞으로도 내시경의 발달과 그 보조 기구의 발달로 인하여 전신 마취 없이 유연형 내시경을 사용한 이물의 제거는 활발히 이루어져야 할 것이고 처음에 시도하는 치료 방법으로 선택되어져야 할 것이다.

Background: Dental phobia or anxiety of patients is the serious impediment to appropriate and effective dental treatment. Sedative technique helps to mitigate patients' fear and anxiety thus make them more cooperative and familiar to dental practices. With increasing attention to sedative dentistry in dentists, educational requirements and technical qualification also become stricter but actual survey on recent sedative dentistry has not been reported yet. Especially there is insufficient study reporting the survey of sedative dentistry subjected to Korean adults. In this paper, we conducted a survey study on the actual condition and practice related to sedation with a questionnaire to dentists in South Korea. Methods: The survey was done for members of The Korean Dental Society of Anesthesiology (KDSA), who had great interest in sedation and for whom survey-by-mail was convenient. 472 members of The KDSA having dental license and solid address and contact information were subjected to the survey by sending them survey questions about their sedative techniques and knowledge. In order to increase the response rate, small gifts were presented to those who accurately responded to the survey questions and text messages and phone calls were made to encourage their participation. We collected their responses over two months and examined the returned surveys. Statistical analysis was performed using IBM SPSS Statistics 21 for each question. Results: Out of 472 dentists, 181 responded (38.4% response rate). 63.0% (114 dentists; 77 male and 37 female) of respondents had experience on sedative technique and their average age was $39.8{\pm}7.6$ year. 74 of them were private practitioners, 17 of them were professors (14.9%), 11 of them were dentists-in-service (9.6%), 11 of them were residents (specialist training) (9.6%) and 1 of them was military doctors (0.9%). There were 89 dentists (78.1%) who were specialists or receiving trainings to be specialist, most of whom were pediatric dentists (55, 48.2%) and oral surgeon (31, 27.2%). The most popular route for drug medications was orderly oral, inhalational, intravenous medication. Combination of oral and inhalational medications or single use of intravenous medication was the most common. The most preferred sedative drug was pocral in oral sedation and midazolam in intravenous sedation. 48.2% of practitioners responded that they experienced side effects and emergency situations. Airway obstruction was the most frequent. Conclusions: Results from the survey show that the protocol and system for sedative dentistry have been improved compared to the past. Nevertheless, quality of emergency protocol, monitoring devices and preparation of sedative drugs was still insufficient to achieve safe sedative procedure. This study acquires novelty since actual survey on recent sedative dentistry for adult patients has not been reported yet.

진정요법을 위한 경구 투여 약물에는 비교적 안전하고 부작용이 적은 것으로 알려진 chloral hydrate가 있으나, 체내에 흡수되는 용량이 환자에 따라 다양하여 이것에 대한 정확한 측정이 어렵고, 환자의 불안 정도와 주변환경 등의 영향을 받아 약효발현이 충분히 이루어지지 않는 경우가 적지 않다. 이런 경우 환자와 보호자 모두에게 고통과 불편함을 줄 수 있으며, 재내원시의 치료도 더욱 어려워지는 고충을 흔히 겪게 된다. 이런 문제점을 해결하기 위해 chloral hydrate와 midazolam의 추가 투여, chloral hydrate와 hydroxyzine, 또는 아산화질소-산소와 함께 사용하는 등 소아환자의 행동조절을 위한 많은 연구와 노력이 시행되어지고 있다. 본 증례에서는 Chloral hydrate 경구 투여 후 진정효과가 나타나지 않은 37명의 소아환자에게 아산화질소-산소와 함께 Enflurane을 사용하여 초기 수면을 유도하여 다음과 같은 결과를 얻었다. 1. Enflurane 투여 및 국소마취 시행시 말초동맥혈 산소 포화도와 이완기 혈압의 변화는 관찰되지 않았으며 정상범위 내에서 안정된 양상을 보였다(p<0.05). 2. Enflurane 투여 및 국소마취 시행시 심박수와 수축기 혈압의 일시적인 변화가 관찰되었지만 곧 정상범위 내로 회복되었으며 안정되었다(p<0.05). 3. Enflurane 투여 후 바람직한 행동양상(Q:Quiet)의 증가를 관찰할 수 있었다. 4. 안정된 생징후와 바람직한 행동양상으로 재 내원의 약속을 하지 않고 97%이상이 치료를 성공적으로 마칠 수 있게 되어 환자, 보호자, 술자 모두에게 만족할 만한 결과를 준 것으로 평가되었다.

Chloral hydrate(CH)는 100년이상 동안 진정용 약물로 이용되어 왔다. CH는 1832년 처음 합성되었고, 1861년에는 진정제의 특성이 소개되었으며, 1869년 이후부터는 합성기술의 발달로 이용 빈도가 증가되었다. 1894년 소아에게 CH를 사용하기 시작한 기록이 있다. CH는 최근까지도 안정성에 관한 많은 논란들이 있었음에도 저렴한 가격과 비교적 안전하다는 경험적 이유로 어린이의 치과 진정법에 여전히 사용되고 있다. 그러나, 2006년 미국 FDA의 권고 이후, 2012년부터 미국내 제약회사는 CH를 더 이상 생산하지 않고 있다. 그럼에도 여전히 미국 내 여러 지역에서는 CH 원재료를 이용하여 조제한 현탁액 형태로 진정법에 사용하고 있으며, 2012년 이후에도 사망과 관련한 부작용의 보고는 계속되고 있다. CH는 현재까지 한국에서 소아 진정법에 가장 많이 이용되고 있는 약제이며, 최근 한국에서도 다수의 부작용에 관련한 보고들이 있었다. 최근 진정법을 이용한 소아의 치과치료에, CH를 대신하여 dexmedetomidine, propofol 등 여러 약물들이 소개되었다. 다만 이들을 소아치과 영역에서 사용하는데 있어서는 여러 가지 제한점이 있으며 고려해 볼 사항들도 많다. 이에 CH와 관련된 합병증들과 한국에서의 사용 실태, 그리고 CH를 대체할 수 있는 약물에 대해 알아보고자 한다.

A 14 kg, 9-year-old, spayed female, Cocker Spaniel was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of head tilt and circling. Otitis externa and media were diagnosed by computerized tomography, and total ear canal ablation was performed. In preanesthetic evaluation, systemic hypertension and second-degree atrioventricular block were observed, but there was no regurgitation through the heart valves. Systemic hypertension was managed with amlodipine (0.1 mg/kg, PO, BID) for the anesthesia. The dog was premedicated with cefazolin (22 mg/kg, IV) and midazolam (0.2 mg/kg, IV). Anesthesia was induced with alfaxalone (2 mg/kg, IV) and maintained with isoflurane and 100% oxygen following intubation. During surgery, vital signs (heart rate, respiratory rate, blood pressure, end tidal carbon dioxide partial pressure and body temperature) were maintained within normal ranges, but bradycardia was observed and corrected with glycopyrrolate (5 ug/kg IV, twice). During subcuticular suture, electrohemostasis was applied at the incision line, which was close to the trigeminal nerve. In no time at all, heart rate dramatically decreased from 110 to 60 beats per minute. No additional treatment was done because mean blood pressure was maintained above 70 mmHg. The heart rate recovered according to the decrease of end tidal isoflurane concentration and there were no complications associated with the anesthesia and surgery. Sudden bradycardia after electrical stimulation around the trigeminal nerve was considered as trigeminocardiac reflex (TCR). It is recommended to be careful of bradycardia from TCR when electrocautery is used in the craniofacial area during surgery.

Background: Adequate assessment and control of sedation play crucial roles in the proper performance of mechanical ventilation. Methods: A total of 30 patients with various pulmonary diseases were prospectively enrolled. The study population was randomized into two groups. The sedation assessment group (SAG) received active protocol-based control of sedation, and in the empiric control group (ECG), the sedation levels were empirically adjusted. Subsequently, daily interruption of sedation (DIS) was conducted in the SAG. Results: In the SAG, the dose of midazolam was significantly reduced by control of sedation (day 1, $1.3{\pm}0.5{\mu}g/kg/min$; day 2, $0.9{\pm}0.4{\mu}g/kg/min$; p<0.01), and was significantly lower than the ECG on day 2 (p<0.01). Likewise, on day 2, sedation levels were significantly lower in the SAG than in the ECG. Significant relationship was found between Ramsay sedation scale and Richmond agitation-sedation scale (RASS; $r_s$=-0.57), Ramsay Sedation Scale and Bispectral Index (BIS; $r_s$=0.77), and RASS and BIS ($r_s$=-0.79). In 10 patients, who didn't require re-sedation after DIS, BIS showed the earliest and most significant changes among the sedation scales. Ventilatory parameters showed significant but less prominent changes, and hemodynamic parameters didn't show significant changes. No seriously adverse events ensued after the implementation of DIS. Conclusion: Active assessment and control of sedation significantly reduced the dosage of sedatives in patients receiving mechanical ventilation. DIS, conducted in limited cases, suggested its potential efficacy and tolerability.

Major purposes of this study were to investigate the administration patterns of analgesics and sedatives in SICU and to identify the factors influencing the use of prn analgesics and sedatives by ICU nurses. The sample of this descriptive study was 50 adult patients in SICU and 53 ICU nurses. Patient's medical records were reviewed to investigate names, doses, the routes of administration, the interval of administration, and the type of prescription of sedatives and analgesics administered. Study medications were narcotics, hypnotics, and antipsychotics. To identify the factors influencing the use of prn analgesics and sedatives, 53 ICU nurses checked 9 items, and rank them from first to fifth. The selection of items was based on the previous studies and the experience of the investigator. The results of the study are as follows: 1. The mean age of the subjects was 53 years, 24 patients out of 50 subjects had received mechanical ventilation therapy. Most of the patients received neurosurgeries and abdominal surgeries. 2. For 4 days, 13 total study medications and combination of these were administered to the patients. Commonly prescribed drugs were Ketoprofen and Midazolam. Twenty six to fourty two percent of the patients did not receive any drugs for at least one day during the four days. 3. On the average, the study drugs were administerd 1.4 to 2.6 times per day during 4 days. 4. More than 50 percent of the prescription was as-needed (prn) except those of the POD 3. Fourteen percent of the patients did not have any prescription for sedation and pain control after surgery. 5. Examination of the frequency of sedatives and analgesics bolus administration revealed that a greater number of doses were given during daytime (from 7 am. to 7 pm.) than nighttime (from 7 pm. to 7 am.). The difference was significant at Alpha, .05. 6. First factor that most influenced nurses to administer sedatives and analgesics for intubated patients was the evaluation of patient's vital signs (51%). For non- intubated patients, the factors that nurses considered important were the patients' complaints of pain (64%) and evaluations of patients' vital signs (23%). In conclusion, the results of this study indicate that patients in SICU might not receive enough analgesics and sedatives to feel completely free from pain during the post operational period. Future study should be focused on the evaluation of the adequacy of current practice for pain and anxiety control in terms of the SICU patient's response.
