  • Autism patients in general have bad oral hygiene. It is hard for autism patients to get dental treatment as poor communication. Therefore, they may have to be treated by deep sedation or general anesthesia in numerous cases. However, this process requires induction with mask, so it is not easy to do for disobliging autism patient. Midazolam is a water-soluble benzodiazepine, has been used in pediatric dentistry or dentistry for the handicapped because of rapid onset. Midazolam can be administered through oral, rectal, intramuscular,intravenous, and intranasal (IN) routes. IN route of midazolam may be considered as effective way to allay for uncooperative autism patients before general anesthesia. In this case report, two autism patients required dental treatment. Intranasal spray of midazolam before general anesthesia was safe and effective procedure of behavioral management.

  • Propofol(2, 6-diisopropylphenol) is rapid, short-acting intravenous anaesthetic agent. It is used for the induction and maintenance of general anaesthesia or sedation. The recommended doses are 2-2.5mg/kg given as a titration infusion over about 30min to achieve anaesthesia. Recently, we encountered 4 fatalities related to propofol. One death is a suicide by self-administered of propofol and the others are therapeutic misadventures during surgical care. The propofol level in the blood and tissues were determined by gas chromatographic analysis with mass spectral detection. (omitted)

  • Background: Ondansetron is both a central and peripheral serotonin (5HT) receptor antagonist and droperidol is a dopaminergic blocking drug which acts centrally at the chemoreceptor trigger zone. We assessed the efficacy and adverse effects of ondansetron, droperidol or both, in the prevention of postoperative emesis during postoperative intravenous patient-controlled analgesia (PCA) using butorphanol and ketorolac medication. Methods: We studied 60 women, aged 25-60 yrs, who underwent total abdominal hysterectomy (TAH), under general anesthesia using $N_2O-O_2$-enflurane. A bolus dose of 1 mg of butorphanol and 4 mg of ondansetron were given to patients and thereafter, PCA was started using 10 mg of butorphanol and 240 mg of ketorolac mixed into the 5% D/W solution (total volume; 100 ml, 1 ml of bolus dose, and 10 min of lockout interval). We also added ondansetron 4 mg (Group O, n = 20), ondansetron 4 mg and droperidol 2.5 mg (Group OD, n = 20), or droperidol 2.5 mg (Group D, n = 20) to the PCA drug. The severity of pain, nausea, vomiting, sedation and other side effects were assessed at 0, 1, 2, 6, 12, 24, 36 and 48 hr after awakening. Results: There was no difference in the incidence of nausea and vomiting between the three group [Group O: 4 (20%) and 3 (15%), respectively; Group OD: 1 (5%) and 1 (5%), respectively; Group D: 3 (15%) and 3 (15%), respectively]. Group O showed a lower sedation score than the other groups (P < 0.05). The pain score and other side effects did not show any difference between the groups. Conclusions: The combination of ondansetron and droperidol showed no clinical benefit compared with ondansetron or droperidol alone for prevention of postoperative nausea and vomiting during postoperative PCA using butorphanol and ketorolac.

  • The purpose of this study is to compare the postoperative analgesic effect of morphine and meperidine, employing intravenous patient controlled analgesia after cesarean section. Among fifty nine parturients undergoing cesarean section with general anesthesia, 32 were administered morphine designated as 'morphine group', and 27 parturient administered meperidine as 'meperidine' group, during 48 hours after commencement of PCA. Doses administered, based on potency for this setting, were equivalent to 1 mg morphine or 10 mg meperidine. Loading dose was administered when parturient first complained of pain after cesarean section. This was followed with bolus dose, 1 mg for morphine group and 10 mg for meperidine group, with a lockout interval of 8 minutes between doses wherever parturient requested additional analgesia. Visual analog scale(VAS) pain scores during rest were significantly lower at only 1 and 2 hour for the meperidine group, than morphine group. Loading dose and cumulative dose at 1, 2 and 3 hours were significantly lower for meperidine group than the morphine group. There were no significant difference in total dose and hourly dose for 48 hours and cumulative dose at 6, 12, 24, and 48 hours between both groups. More than 90% of the parturients from both groups were satisfied with the analgesic effects of pain relief. Morphine group experienced side effects such as: pruritus, sedation and dizziness. Meperidine group had sedation, dizziness, nausea and local irritation. Neither group required any specific treatment for any of the above side effects. We conclude that meperidine had greater analgesic effect at early stage of post-operative period.

  • Background/Aims: Bispectral index (BIS) monitors process and display electroencephalographic data are used to assess the depth of anesthesia. This study retrospectively evaluated the usefulness of BIS monitoring during endoscopic ultrasonography (EUS). Methods: This study included 725 consecutive patients who underwent EUS under sedation with propofol. BIS monitoring was used in 364 patients and was not used in 361. The following parameters were evaluated: (1) median dose of propofol; (2) respiratory and circulatory depression; (3) occurrence of body movements; (4) awakening score >8 at the time; and (5) awakening score 2 hours after leaving the endoscopy room. Results: The BIS group received a significantly lower median dose of propofol than the non-BIS group (159.2 mg vs. 167.5 mg; p=0.015) in all age groups. For patients aged ≥75 years, the reduction in heart rate was significantly lower in the BIS group than in the non-BIS group (1.2% vs. 9.1%; p=0.023). Moreover, the occurrence of body movements was markedly lower in the BIS group than in the non-BIS group (8.5% vs. 39.4%; p<0.001). Conclusions: During EUS examination, BIS monitoring is useful for maintaining a constant depth of anesthesia, especially in patients 75 years of age or older.

  • 플루마제닐은 벤조다이아제핀계 약물의 길항제로서, 정주로를 통하여 체내에 투여된다. 그러나 정주로가 확보되지 않은 상태에서 플루마제닐의 길항작용이 필요할 때에는 정주로 이외의 체내 투여로가 요구된다. 본 연구에서는 미다졸람으로 심진정을 유도한 후 플루마제닐의 경비투여로 인한 의식 상태의 가역을 임상시험하였다. 성인남녀 25명을 대상으로 미다졸람을 소량씩 0.08mg/kg까지 투여하여 의식소실을 유도하였다. 미다졸람 투여 10분 후 플루마제닐 0.5mg을 1분 동안 주사기를 이용하여 천천히 경비투여하였다. 환자감시에는 심전도, 자동혈압계, 호기말 이산화 탄소분압 백박산소포화도 등을 사용하였다. 진정의 정도는 진정점수와 뇌파감시를 이용한 bispectral index로 평가하였다. 플루마제닐 투여 직전에 미다졸람과 플루마제닐의 혈중 농도를, 플루마제닐 투여 후 5, 10, 및 20분 후에 혈청 플루마제닐 농도를 측정하였다. 플루마제닐의 경비투여 후 완전한 길항효과를 나타낸 경우는 전체 25명 중 2명이었다. 혈청 플루마제닐의 농도는 투여 10분 후에 최고치에 도달하였고, 20분간 지속되었다. 진정점수는 미다졸람 투여 후 증가한 뒤 플루마제닐 투여 후 유의하게 감소하였다(p<0.05). 그러나 bispectral index는 미다졸람 투여 후 시간경과에 따라 유의하게 감소하였으나, 플루마제닐 투여후에는 유의 한 변화를 보이지 않았다. 결론적으로 0.1m/ml 농도의 플루마제닐 0.5mg 경비투여는 미다졸람으로 유도된 심진정시 길항효과가 완전하지 않았으나, 경비투여 후 혈액에서 플루마제닐의 농도측정이 가능하였다는 결과는 임상사용 가능성을 제시하며 정주용으로 사용되는 플루마제닐의 농도가 낮은 점을 보완할 수 있는 새로운 제재의 고안이 필요하다고 생각된다.lis 단독 배양시 ml당 $2.1\times10^8$ 이었으나, S. oralis와 4주의 분리균주 혼합 배양시 S. oralis는 $1.4\times10^7$ 내지 $7.0\times10^7$으로 감소되었다. 6. 3주의 분리균주로 부터 약 60 kb의 plasmid를 분리 할 수 있었다. 이상의 결과를 종합하면 구강에서 분리된 E. durans는 S. mutans의 증식을 억제하여 인공치태 형성을 저지하였고, S. oralis의 증식은 약간 억제하였다.5), II군과 I군간에는 유의한 차이를 보이지 않았다 (p>0.05). 본 실험에서 시도한 두 가지 진정요법이 비교적 높은 임상적 치료 성공률(II군 : 97.14%, III군 : 88.57%)을 보여 만족할 만한 결과를 나타낸 것으로 평가되었다.tosan film보다 큰 수증기 투과도를 보였다.적으로 유의한 차이를 보이지 않았다.y tissue layer thinning은 3 군모두에서 관찰되었고 항암 3 일군이 가장 심하게 나타났다. 이상의 실험결과를 보면 술전 항암제투여가 초기에 시행한 경우에는 조직의 치유에 초기 5 일정도까지는 영향을 미치나 7 일이 지나면 정상범주로 회복함을 알수 있었고 실험결과 항암제 투여후 3 일째 피판 형성한 군에서 피판치유가 늦어진 것으로 관찰되어 인체에서 항암 투여후 수술시기는 인체면역계가 회복하는 시기를 3주이상 경과후 적어도 4주째 수술시기를 정하는 것이 유리하리라 생각되었다.한 복합레진은 개발의 초기단계이며, 물성의 증가를 위한 연구가 필요할 것으로 사료된다.또 다른 약물인 glycyrrhetinic acid($100{\mu}M$)도 CCh 자극으로 인한 타액분비를 억제하였다. 이상의

  • Background: In dental intravenous sedation, continuous intravenous infusion of a low-dose drug requires an infusion pump such as a syringe pump. To develop a new syringe pump for clinical use, the functions of the pump must meet certain international standards. Various safety and efficacy tests must be performed on the syringe pump, as stipulated by these standards, and an approval must be received from the approving agency based on such test results. Methods: The authors of the present study developed a novel syringe pump and performed efficacy evaluation by testing its infusion speed at 1 and 25 ml/h, and infusion performance testing at 2 and 24 h. Moreover, performance evaluation was conducted by comparing the novel pump to an existing pump with the infusion speed varied from 1 to 5 ml/h. Results: In the efficacy testing on the newly developed syringe pump, infusion with the infusion speed initially set to 1 ml/h resulted in infusion speeds of 1.00 and 0.99 ml/h in the 2- and 24-h assessment, respectively. Changing the infusion speed setting to 25 ml/h resulted in an infusion speed of 25.09 and 23.92 ml/h in the 2- and 24-h assessment, respectively. These results show no significant differences when compared with other commercially available pumps. Conclusions: The efficacy testing of the newly developed syringe pump showed the accuracy to be within tolerance. Based on these findings, we believe that the newly developed syringe pump is suitable for clinical use.

  • Background: Ketorolac($Tarasyn^{(R)}$) is a non-steroidal anti-inflammatory drug(NSAID) which has shown to be an effective postoperative analgesic available parenterally, and when combined with morphine can reduce its requirement. The analgesic efficacy and adverse effects of continuous infusion of ketorolac added to morphine IV PCA was evaluated in 60 women after abdominal hysterectomy. Methods: Patients were assigned to receive either morphine intravenous(IV) bolus followed by morphine IV patient controlled analgesia(PCA), or ketorolac 30mg IV and continuous IV infusion at 4.0mg/hr in combination with the above regimen. The authors evaluated PCA morphine used, pain assessment(verbal pain intensity score and visual analogue scale) and side effects at 2, 4, 6 and 24hrs during pain control. Results: Continuous infusion of ketorolac decreased the PCA morphine usage significantly(30.4 ---> 19.6 mg : p=0.007) at 24hrs postoperatively. Significant differences were seen favoring ketorolac infusion in pain intensity and visual analogue scale both at rest and during movement. There were no differences in incidences of deep sedation, nausea & vomiting. But the ketorolac group they complained of dizziness more than morphine only group. Little pruritus was recorded in either groups. Conclusions: The authors conclude continuous IV infusion of ketorolac in conjunction with morphine PCA provide effective analgesia after low abdominal surgery.

  • Background: Myringotomy with tympanostomy tube insertion (MTI) is a superficial surgical procedure used to prevent hearing loss in children with serous otitis media. Intravenous anesthesia, often ketamine, is preferred for this procedure because of its ability to induce sedation without compromising airway reflexes. However, ketamine alone may be insufficient and potentially lead to spontaneous movement during surgery. This study evaluated the effectiveness of midazolam and fentanyl as adjuvants to ketamine in reducing spontaneous movement during MTI and enhancing the quality of recovery. Methods: This study involved two groups of 30 patients each: one group received intravenous ketamine (1.5 mg/kg) with an equal volume of normal saline (K group), while the other received a combination of midazolam, fentanyl, and ketamine (0.05 mg/kg, 1 ㎍/kg, and 1.5 mg/kg, respectively; MFK group). We assessed side effects, intraoperative patient movement, surgeon satisfaction, and emergence agitation scores. Results: The MFK group exhibited significantly lower scores for patient movement (p<0.01) and emergence agitation (p<0.01) and markedly higher surgeon satisfaction scores (p<0.01) than the K group. Conclusion: Administering a midazolam-fentanyl-ketamine combination effectively reduced spontaneous movement during surgery and emergence agitation during recovery without prolonging discharge times in children undergoing MTI.
