BACKGROUND: We aimed to assess the dose needed to achieve the propofol effect-site concentration using target-controlled infusion in intellectually disabled patients and to detail the most effective method for achieving a safe level of consciousness without hemodynamic changes as well as detail any resulting adverse effects. METHODS: We performed a retrospective review of sedation service records of 138 intellectually disabled patients (51, mental retardation; 36, autism; 30, brain lesion, 12 genetic diseases, 9 dementia) aged over 15 years and weighing over 30 kg. These patients had received propofol via target-controlled infusion in the special care dental clinic of Seoul National University Dental Hospital from May 2008 to September 2018 for restorative treatment (112), minor surgery (13), prosthodontics (7), periodontics treatment (5), and implant (1). RESULTS: For all groups, the duration of dental treatments was 43 ± 18 minutes, total sedation time was 73 ± 23 minutes, and total BIS values was 57 ± 12. The propofol maintenance dosage values for each group were: mental retardation, 3 ± 0.5 (2–4) µg/ml; autism, 3.1 ± 0.7 (2–5) µg/ml; brain lesion, 2.8 ± 0.7 (1.5–5) µg/ml; genetic disease, 2.9 ± 0.9 (1–4) µg/ml; and dementia 2.3 ± 0.7 (1–3.4) µg/ml. CONCLUSIONS: The dementia group needed a lower dosage to reach a safe, effective propofol effect-site concentration than the other groups. Since there were no complications, deep sedation is a great alternative to general anesthesia for dental treatment of intellectually disabled patients.

The purpose of this study was to analyze outpatient referral patterns of children in Jeonbuk National University Dental Hospital. All patients under 16 years old who were consulted from the external facilities were reviewed based on the electronic medical record of Jeonbuk National University Dental Hospital from 2015 to 2018.Total 720 boys and 460 girls with an average age of 7.4 years were referred from local dental clinic (85.2%) for treatment severity (90.2%). 3.2% of patients has disability with the highest number of intellectual disabilities. The patients were usually referred at the pre-treatment stage with higher rates if they had disability or medical problem. Referral rate by chief complaints was highest in surgery, followed by reparative treatment and orthodontic treatment. 2(nd) referrals in pediatric dentistry had a higher rate of referrals to minor surgery and pulp treatment than of first referrals. The time point of 2(nd) referral was relatively delayed with increased ratio of ‘during treatment’.These results suggest necessities of appropriate case selection and referral based reasonable criteria for pediatric dentist.

Chemodenervation with botulinum toxin (BTX) has been recommended for focal spasticity. BTX injection should be performed with caution in patients with bleeding disorders and/or receiving anticoagulation therapy. We present a case of BTX injection for post-stroke spasticity in a patient with hemophilia A who could not take oral spasmolytics due to chronic hepatitis C. To minimize the bleeding risk, we replaced factor VIII intravenously in accordance with the World Federation of Hemophilia guidelines for minor surgery. FVIII (3,000 IU) was administered 15 minutes before BTX injection. One day later, 2,000 IU was administered, and 2 days later, another 2,000 IU was administered. We performed the real-time Ultrasound-guided BTX injection three times, then spasticity and upper extremity function improved without adverse events. BTX injection can be considered as a treatment option for spasticity among patients with hemophilia.

BACKGROUND: Anxiety control remains an important concern in dental practice. We evaluated the incidence, nature, and sequelae of complications during and after minor oral surgeries performed under intravenous midazolam and fentanyl sedation using the titration technique. METHODS: The medical records of patients who had undergone minor oral surgeries under moderate intravenous midazolam and fentanyl sedation at our institution between January 1, 2015 and December 31, 2015 were retrospectively evaluated. Age, sex, body mass index, medical history, American Society of Anesthesiologists (ASA) classification, indications for sedation, amount of sedative used, surgical duration, and recovery time were evaluated for all patients. RESULTS: In total, 107 patients aged 9–84 years were included. ASA class I and class II were observed for 56.1% and 43.9% patients, respectively. Complications associated with sedation occurred in 11 (10.2%) patients. There were no serious adverse events. Oxygen saturation reached 95% during the procedure in six patients; this was successfully managed by stimulating the patients to take a deep breath. Two patients exhibited deep sedation and one exhibited paradoxical excitement. After the procedure, one patient experienced nausea without vomiting and one exhibited a prolonged recovery time. The surgical procedures were completed in all patients. Obesity was found to be significantly associated with sedation-related complications. CONCLUSIONS: Our results suggest that complications associated with intravenous midazolam and fentanyl sedation using the titration technique for minor oral surgeries are mostly minor and can be successfully managed with no prolonged sequelae.

Oral anticoagulant therapy is frequently and increasingly prescribed for patients at risk of arterial or venous thromboembolism (VTE). Although elective surgical or invasive procedures have necessitated temporary interruption of anticoagulants, managing these patients has been performed empirically and been poorly investigated. This study was designed to evaluate the adequacy of perioperative anticoagulation using enoxaparin. This was a retrospective, single-center study that evaluated the efficacy and safety of therapeutic-dose enoxaparin for bridging therapy in patients on long-term warfarin at Soonchunhyang University Hospital in Korea between August 2009 and July 2011. Warfarin was discontinued 5 days before surgery, and enoxaparin was administered twice daily by subcutaneous injection at a dose of 1 mg per kg from 3 days before the procedure to the last dose 24 hours before the procedure. Anticoagulation was restarted if proper hemostasis had been confirmed. There were 49 patients, of whom 25 (51%) were men, and the mean age was 63 years. Thirty-four (69%) received warfarin therapy for VTE, and 9 (18%) for atrial fibrillation. Twenty-nine patients (59%) underwent major surgery and 20 (41%) minor surgery. The mean postoperative duration of enoxaparin was 4 days. No patients had thromboembolic complications through 30 days after the procedure. The overall 30-day mortality rate was 0%. In conclusion, our findings demonstrate that bridging therapy with therapeutic-dose enoxaparin is feasible and associated with a low incidence of major bleeding and no thromboembolic complications. However, the optimal approach to managing patients perioperatively is uncertain and requires further evaluation.

BACKGROUND: Although circumcision for phimosis in children is a minor surgical procedure, it is followed by pain and carries the risk of increased postoperative anxiety. This study examined predictive factors of postoperative pain and anxiety in children undergoing circumcision. METHODS: We conducted a prospective cohort study of children scheduled for elective circumcision. Circumcision was performed applying one of the following surgical techniques: sutureless prepuceplasty (SP), preputial plasty technique (PP), and conventional circumcision (CC). Demographics and base-line clinical characteristics were collected, and assessment of the level of preoperative anxiety was performed. Subsequently, a statistical model was designed in order to examine predictive factors of postoperative pain and postoperative anxiety. Assessment of postoperative pain was performed using the Faces Pain Scale (FPS). The Post Hospitalization Behavior Questionnaire study was used to assess negative behavioral manifestations. RESULTS: A total of 301 children with a mean age of 7.56 +/- 2.61 years were included in the study. Predictive factors of postoperative pain measured with the FPS included a) the type of surgical technique, b) the absence of siblings, and c) the presence of postoperative complications. Predictive factors of postoperative anxiety included a) the type of surgical technique, b) the level of education of mothers, c) the presence of preoperative anxiety, and d) a history of previous surgery. CONCLUSIONS: Although our study was not without its limitations, it expands current knowledge by adding new predictive factors of postoperative pain and postoperative anxiety. Clearly, further randomized controlled studies are needed to confirm its results.

BACKGROUND: This study was designed to find appropriate lubricant for streamed lined liner of pharyngeal airway(TM) (SLIPA(TM)). We evaluated the incidence of sore throat, nausea, vomiting, hoarseness, paresthesia and blood stain after using saline, water soluble gel and 2% lidocaine gel as a SLIPA(TM) lublicant. METHODS: One hundred twenty three patients scheduled for minor surgery to whom the SLIPA(TM) was considered suitable were randomly allocated to one of three groups which receive normal saline, water soluble gel or 2% lidocaine gel as a SLIPA(TM) lublicant. Patients were interviewed at recovery room, post operation 6-12 hour, post operation 18-24 hour about sore throat and other complications. RESULTS: There were no statistical difference in sore throat and blood stain among three groups. Also there were no statistical differences in hoarseness, nausea, vomiting. The incidence of paresthesia in 2% lidocaine gel group was significantly higher than those of the other two groups immediately after operation, but it was resolved after leaving the recovery room. CONCLUSIONS: Our results suggest that normal saline, water soluble gel and 2% lidocaine gel are all available as a SLIPA(TM) lubricant. Size of SLIPA(TM), insertion technique and difficulty of insertion should be further investigated as the main causes of a sore throat and other complications which can occur after the insertion of SLIPA(TM).

OBJECTIVES: Patients with cervical ossification of posterior longitudinal ligament (OPLL) are susceptible to cord injury, which often develops into myelopathic symptoms. However, little is known regarding the prognostic factors that are involved in minor trauma. We evaluated the relationship between minor trauma and neurological outcome of OPLL and investigated the prognostic factors with a focus on compressive factors and intramedullary signal intensity (SI). METHODS: A total of 74 patients with cervical myelopathy caused by OPLL at more than three-levels were treated with posterior decompression surgeries. We surveyed the space available for spinal cord (SAC), the severity of SI change on T2-weighted image, and diabetes mellitus (DM). The neurological outcome using Japanese Orthopedic Association (JOA) scale was assessed at admission and at 12-month follow-up. RESULTS: Among the variables tested, preoperative JOA score, severity of intramedullary SI, SAC, and DM were significantly related to neurological outcome. The mean preoperative JOA were 11.3+/-1.9 for the 41 patients who did not have histories of trauma and 8.0+/-3.1 for the 33 patients who had suffered minor traumas (p<0.05). However, there were no significant differences in the recovery ratios between those two groups. CONCLUSIONS: Initial neurological status and high intramedullary SI in the preoperative phase were related to poorer postoperative outcomes. Moreover, the patients with no histories of DM and larger SACs exhibited better improvement than did the patients with DM and smaller SACs. Although the initial JOA scores were worse for the minor trauma patients than did those who had no trauma prior to surgery, minor trauma exerted no direct effects on the surgical outcomes.

BACKGROUND: We compared the postoperative analgesic efficacy of caudal levobupivacaine with bupivacaine in pediatric subumbilical surgery. METHODS: Sixty American Society of Anesthesiologists I-II patients scheduled for elective minor surgery (1.5-7 years old) were randomly divided into three groups to receive caudal injections of study drugs at 0.5 ml/kg. All patients received 0.1 mg/kg oral midazolam 30 min before surgery. Group B received 0.125% bupivacaine, group L received 0.125% levobupivacaine, and group LF received 0.125% levobupivacaine + 0.5 microg/kg fentanyl. Blood pressure, heart rate and sedation (using a four-scale sedation score) were monitored perioperatively. During the postoperative period, an anesthesiologist blinded to the study groups used the Children's and Infants' Postoperative Pain Scale to monitor patients' pain and degree of sedation. The time before the first rescue analgesic was recorded as well as any side effects over the next 24 h. RESULTS: The four-scale sedation and postoperative pain scale scores in all groups were identical. Blood pressure and heart rate measured at 15 min postoperatively were lower, and time to first rescue analgesic was longer, in Group LF compared to the others. CONCLUSIONS: Caudal 0.5 ml/kg of 0.125% bupivacaine and levobupivacaine are equally effective for postoperative analgesia after subumbilical surgeries in pediatric patients. Addition of fentanyl may lower the required amount of local anesthetics.

PURPOSE: In earlier analyses, desflurane has been shown to reduce average extubation time and the variability of extubation time by 20% to 25% relative to sevoflurane in adult patients. We undertook this study to determine which agents prompt less recovery time in pediatric patients undergoing minor surgery. MATERIALS AND METHODS: After obtaining Institutional Review Board approval, we retrospectively reviewed the anesthesia records of 499 patients, with an average age of 5 years, who underwent minor surgeries at Severance Eye and Ear, Nose and Throat Hospital between May 2010 and April 2011. Anesthesia was induced with propofol and rocuronium. Anesthesia was maintained with sevoflurane (n=340) or desflurane (n=159) with 50% air/O2. Time from cessation of anesthetics to recovery of self-respiration, eye opening on verbal command and extubation were compared between the two groups. Additionally, the incidences of postoperative respiratory adverse events were also compared. RESULTS: Times to self-respiration recovery, eye opening on verbal command, and extubation were significantly faster in the desflurane group than the sevoflurane group (4.6+/-2.5 min vs. 6.9+/-3.8 min, 6.6+/-3.0 min vs. 9.2+/-3.6 min, and 6.2+/-2.7 min vs. 9.3+/-3.7 min, respectively, p<0.005). There were no statistically significant differences between the two groups with respect to adverse respiratory events during the peri-operative period (38.2% vs. 34.6%, p=0.468). CONCLUSION: Emergence and recovery from anesthesia were significantly faster in the desflurane group of children undergoing minor surgery. Desflurane did not result in any differences in respiratory adverse events during recovery compared to sevoflurane.
