Background: The purpose of this study is to investigate the effects of administration order when a sedative drug (midazolam) and an opioid analgesic drug (fentanyl) is applied for moderate intravenous (IV) sedation in dentistry. Methods: A retrospective chart review was conducted in one dental clinic during its transition from a midazolam-first to a fentanyl-first protocol for dental procedures requiring moderate IV sedation. Physiological parameters, drug administration times, patient recovery times, drug dosages, and patient recall and satisfaction were investigated for differences. Results: A total of 76 charts (40 midazolam-first and 36 fentanyl-first administrations), were used in the analysis. Administering midazolam first resulted in an average 4.38 min (52%) decrease in administration times (P < 0.001), and a decrease in procedural recollection immediately following the procedure (P = 0.03), and 24 to 48 hours later (P = 0.009). Administering fentanyl first required an average of 2.43 mg (29%) less midazolam (P < 0.001). No significant differences were found for change in vital signs, minimum oxygen saturation levels, recovery times, and patient satisfaction (P > 0.05). Oxygen saturation levels did not drop below 90% for either group; however, 5 cases in the fentanyl-first group fell to between 90% and 92%, compared with 0 cases in the midazolam-first group. Conclusions: The administration order of fentanyl and midazolam may have different effects on patients and the sedation procedure. Findings from this study should be used to facilitate discussion among dental practitioners and to guide additional research investigating this topic.

Myasthenia gravis (MG) is a neuromuscular autoimmune disorder which clinically presents as muscular weakness and fatigue due to autoantibody formation against acetylcholine receptors (AChR), leading to their subsequent destruction. Due to the neuromuscular implications of MG, certain considerations must be taken into account when providing anesthesia to MG patients. In the following case report, we have outlined procedural considerations for the anesthetic management of a patient with MG undergoing deep sedation for an elective oral surgery in an outpatient setting, as well as a discussion of relevant literature.

Purpose: The aim of this study was to assess the clinical efficacy of combined treatment with local anesthesia and ketamine procedural sedation for pediatric facial laceration repair in the Emergency Department (ED). Methods: Patients aged 1 to 5 years receiving ketamine for facial laceration repair were prospectively enrolled in a double-blind, randomized, and controlled study at an ED. All patients were to receive intravenous ketamine (2 mg/kg). The local anesthesia group (LA group) received a local anesthetic along with ketamine, whereas the no local anesthesia group (NLA group) received only ketamine. The total time of sedation, the patients' movements and groans, adverse events, and the satisfaction ratings of physicians, nurses, and parents were recorded. Results: A total of 186 patients were randomized (NLA group: 90, LA group: 96). The total time of sedation (30.5 minutes for the NLA group, 32.6 minutes for the LA group; p=0.660), patients' groans (26 (28.9%) versus 23 (24.0%); 0.446) and movements (27 (30%) versus 35 (36.5%); p=0.350) was not affected by the addition of local anesthesia. Other adverse events were similar between the two groups. Also, the satisfaction ratings of physicians (median 4 for the NLA group versus 4 for the LA group (p=0.796)), nurses (2 versus 2.5 (p=0.400)), and parents (4 versus 4 (p=0.199)) were equivalent between the two groups. Conclusion: In this study, we found that local anesthesia was not required along with ketamine sedation for pediatric facial laceration repair.

Background: In order to assess the effectiveness of various analgesio-sedative combinations for pain relief and sedation in pediatric dental patients, a thorough evaluation of clinical studies and patient outcomes is necessary. Methods: A total of 128 healthy, uncooperative pediatric dental patients were randomly allocated to receive one of the four combinations of drugs via the intranasal (IN) route: Group I received midazolam-ketamine (MK), Group II received dexmedetomidine-ketamine (DK), Group III received midazolam-fentanyl (MF), and Group IV received dexmedetomidine-fentanyl (DF) in a parallel-arm study design. The efficacy and safety of the combinations were evaluated using different parameters. Results: The onset of sedation was significantly faster in the DF group than in the DK, MF, and MK groups (P < 0.001). The depth of sedation was significantly higher in the DK and DF groups than in the MK and MF groups (P < 0.01). DK and DF produced significant intra- and postoperative analgesia when compared with combinations of MK and MF. No significant adverse events were observed for any of the combinations. Conclusions: The DK and DF groups showed potential as analgesio-sedatives in view of their anxiolytic and analgesic effects.

어린이는 쉽게 넘어지거나 부딪혀 구강안면부의 손상을 흔히 경험하며, 응급치료를 필요로 한다. 이러한 환자들에서는 공포와 불안으로 인해 협조도가 불량해지게 된다. 케타민은 일반 응급실에서 어린 환자의 치료와 검사를 위한 진정제로 잘 알려져 있다. 본 연구에서는 원주 세브란스 기독병원 응급실에서 케타민을 이용한 진정법을 시행한 현황에 대해 알아보았다. 2010년 1월에서 2014년 5월까지 치과적 응급처치를 위해 의뢰된 만 18세 이하의 환자들의 기록이 수집되었으며, 연령, 성별, 시행된 치과적 치료, 케타민 진정법 시행 여부에 대한 자료를 분석하였다. 총 659명의 소아 환자가 치과적 응급처치를 필요로 하였으며, 이중 118명이 케타민 진정법이 시행되었다. 조사 결과 열상의 봉합을 시행한 환자에서 진정법이 더 많이 시행되었고, 연령이 어릴수록 진정법이 시행되었던 상관성이 확인되었다. 케타민 진정법은 치과의사 단독으로 사용하지 않아야 하지만, 응급실에서 1차 진료를 담당하는 치과의사는 케타민 진정법이 적용된 환자들을 쉽게 접할 수 있다. 따라서, 응급실에서 근무하는 치과의사는 케타민의 임상적 효과, 고려사항, 그리고 발생 가능한 합병증 및 대처 방안에 대해 숙지하고 있어야 할 것으로 사료된다.

목적: Chloral hydrate는 검사 시 진정 목적으로 흔히 사용하는 약물이나 신생아에 관해서는 충분한 연구가 이루어지지 않고 있다. 이에 저자들은 신생아중환자실에서 chloral hydrate의 사용 시에 나타나는 부작용의 빈도와 그에 영향을 미치는 요소에 대해 알아보고자 한다. 또한 chloral hydrate만으로 진정이 되지 않아 추가 약물을 투여하는 경우 부작용이 증가하는지에 관해 알아보고자 한다. 방법: 2010년 3월부터 2011년 2월까지 가톨릭대학교 서울성모병원 신생아중환자실에서 검사 시 진정 목적으로 chloral hydrate를 사용한 104명을 대상으로 의무기록을 후향적으로 조사하였다. 결과: Chloral hydrate 투여 시 부작용은 41.3%에서 나타났으며 산소 포화도 감소(18.8%), 무호흡 증가(17.5%), 서맥 증가(10%), 수유량 감소(3.8%)가 있었다. Chloral hydrate 투여 시부작용은 chloral hydrate 투여 시기에 산소 투여 여부와 관련이 있었다(odds ratio [OR], 10.911: 95% confidence interval [CI], 2.082-57.178). 추가 약물 투여는 chloral hydrate 투여 시 산소 투여 여부와 관련이 있었고(OR, 4.151: 95% CI, 1.455-11.840) chloral hydrate 단독 투여 군에 비해 수유량 감소를 제외하고는 부작용에 유의한 차이가 없었다. 결론: 진정 요법이 필요한 검사 시 산소를 투여하고 있는 신생아에서 chloral hydrate의 사용은 부작용이 나타날 가능성이 높고 추가 약물 투여의 가능성이 높다. 추가 약물 투여가 필요한 경우에는 진정 유도 후 나타나는 수유량 감소에 주의하면서 진정을 유도할 수 있겠다.

Background: Ketamine is widely used in infants and young children for procedural sedation and anesthesia. The aim of this study was to evaluate the efficacy and safety of low dose oral ketamine to control pain and distress in children during intravenous (IV) cannulation. Methods: This is a prospective, randomized, double-blind study, including children aged between 3 and 6 years requiring a non-emergent IV-line placement. Children were randomly assigned to two groups, treated either with oral ketamine or a placebo. All patients were monitored for vital signs. Pain was assessed using the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) and Wong-Baker Faces Pain Rating Scale (WBFS) scales and sedation using a 5-point sedation score. The facility of IV-line placement was measured by a 3-point scale. Adverse effects were recorded after 1 and 24 hours. Results: A total of 79 and 81 children were entered in the ketamine and placebo groups, respectively. The heart and respiratory rates increased significantly in the placebo group. The median CHEOPS 4 (95% confidence interval [CI]: 3, 4, P < 0.001) and WBFS 6 (95% CI: 4, 6, P < 0.001) scores decreased statistically in the ketamine group. IV-line placement was 50% easier in the ketamine group (95% CI: 37%, 63%, P < 0.001). No serious adverse effects were observed in all cases. Conclusions: Low dose oral ketamine effectively decreased the pain and distress during IV cannulation in children without any significant adverse reactions.

Background: Propofol is a short-acting intravenous sedative widely used for procedural sedation and general anesthesia. However, pain during propofol injection is a distressing adverse effect. This study was designed to investigate whether transcutaneous electrical nerve stimulation (TENS) could reduce pain during propofol injection compared to sham TENS. Methods: In a randomized controlled trial, 80 patients were allocated to two groups: the active TENS group received electrical stimulation via two electrodes on the venous cannulation site, whereas the sham TENS group received no stimulus. After 20 min following TENS, propofol 0.5 mg/kg pain was injected intravenously and pain was evaluated using a four-point score (0 = none, 1 = mild, 2 = moderate, 3 = severe). Adverse effects associated with TENS were also recorded. Results: The overall incidence of pain during propofol injection was 47.5% in the TENS group and 87.5% in the sham group (P < 0.001). The incidence of moderate pain was significantly lower in the TENS group (7.5%) than in the sham TENS group (42.5%) (P < 0.001). There were no complications associated with TENS. Conclusion: Pre-treatment with TENS significantly reduced the incidence and intensity of pain during propofol injection.

Background: At most centers, general anesthesia (GA) has been preferred for endovascular treatment (EVT) of ruptured intracranial aneurysms (RIAs). In this study, we analyzed procedural results, clinical outcomes, and follow-up angiographic findings for patients undergoing EVT for RIA under local anesthesia (LA) with conscious sedation (CS). Methods: We retrospectively evaluated 308 consecutive patients who underwent EVT for RIAs at a single institution between June 2009 and February 2017. EVT under LA with CS was considered for all patients with aneurysmal subarachnoid hemorrhage, regardless of Hunt and Hess (HH) scale score. Results: EVT was performed for 320 aneurysms in 308 patients with subarachnoid hemorrhages. The mean patient age was $55.5{\pm}12.6$ years. Moderate (III) and poor (IV, V) HH grades were observed in 75 (24.4%) and 77 patients (25%), respectively. Complete occlusion immediately after EVT was achieved for 270 (84.4%) of 320 aneurysms. Thromboembolic complications and intraprocedural ruptures occurred in 25 (7.8%) and 14 cases (4.3%), respectively. The morbidity rate at discharge (as defined by a modified Rankin scale score of 3 or greater) was 27.3% (84/308), while the mortality rate was 11.7% (36/308). Follow-up angiographic results were available for 210 (68.1%) of 308 patients. Recanalization was observed in 64 (29.3%) of 218 aneurysms in 210 patients. Conclusion: Based on our experience, EVT for RIAs under LA with CS was feasible, regardless of the clinical grade of the subarachnoid hemorrhage. Complication rates and follow-up angiographic results were also comparable to those observed when GA was used to perform the procedure.
