  • Objectives: To compare the efficacy of intravenous ondansetron (4 mg, 2 mL) and granisetron (2 mg, 2 mL) for preventing postoperative nausea and vomiting (PONV) in patients during oral and maxillofacial surgical procedures under general anesthesia. Materials and Methods: A prospective, randomized, and double blind clinical study was carried out with 60 patients undergoing oral and maxillofacial surgical procedures under general anesthesia. Patients were divided into two groups of 30 individuals each. Approximately two minutes before induction of general anesthesia, each patient received either 4 mg (2 mL) ondansetron or 2 mg (2 mL) granisetron intravenously in a double blind manner. Balanced anesthetic technique was used for all patients. Patients were assessed for episodes of nausea, retching, vomiting, and the need for rescue antiemetic at intervals of 0-2, 3, 6, 12, and 24 hours after surgery. Incidence of complete response and adverse effects were assessed at 24 hours postoperatively. Data was tabulated and subjected to statistical analysis using the chi-square test, unpaired t-test, or the Mann-Whitney U-test as appropriate. A P-value less than 0.05 was considered statistically significant. Results: There was no statistically significant difference between the two groups for incidence of PONV or the need for rescue antiemetic. Both study drugs were well tolerated with minimum adverse effects; the most common adverse effect was headache. The overall incidence of complete response in the granisetron group (86.7%) was significantly higher than the ondansetron group (60.0%). Conclusion: Granisetron at an intravenous dose of 2 mg was found to be safe, well tolerated, and more effective by increasing the incidence of complete response compared to 4 mg intravenous ondansetron when used for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia. Benefits of granisetron include high receptor specificity and high potency, which make it a valuable alternative to ondansetron.

  • The most widely used method of pain control in dental practice is to block the pathway of painful impulses by local anesthesia. For a maximum effect of pain control at outpatient minor operation, regional anesthesia including nerve block must be performed. This issue includes various dental local anesthetic techniques on mandible, maxilla and considerations for selection of dental local anesthetics according to patient's age, duration of operation. Additionally, current conscious sedation technique combined with local anesthesia will be introduced for control of patient's anxiousness. Based on patient's general condition, severity of operation, local anesthesia sometimes must be changed into general anesthesia to avoid failure of dental practice. The exact choice of anesthetic techniques for minor operations at dental outpatient clinic must not be underestimated for complete success of pain control.

  • Oral and maxillofacial surgery (OMFS) trauma cases are commonly treated under general anesthesia. The purpose of this case report is to introduce an alternative method of anesthesia in patients who refuse general anesthesia. A combination of dexmedetomidine and ketamine for sedation anesthesia in 3 frequent fracture types in the field of OMFS-Le Fort I fracture, mandibular fracture, and alveolar bone fracture-was used. Dexmedetomidine as the single agent has not shown stable success rates for invasive procedures. To overcome some of the pitfalls with dexmedetomidine, combination sedation using ketamine was performed. Visual analogue scale scores were recorded postoperatively. Dexmedetomidine combined with ketamine administration provided safe and effective sedation and anxiolysis for surgical reduction and internal fixation of OMFS fractures. It showed advantages of decreased admission time, reduced expenses, minimal pain, and reduced anesthetic burden for the patient thus ultimately increasing overall satisfaction.

  • In this paper, new index was developed to estimate the depth of anesthesia during general anesthesia using EEG. Analysis of the power spectral density(PSD) of EEG was used to develop new parameters because EEG signal tends to have slow wave during anesthesia. Classifier for index creator was developed by using SEF, BDR and BTR parameters, which are calculated by power spectral density. EEG data were obtained from 7 patients (ASA I, II) during general anesthesia with Sevoflurane. The anesthetic depth evaluation indexes ranged from 0 to 100. The average were $86.05{\pm}10.1$, $36.98{\pm}20.2$, $15.33{\pm}13.6$, $50.87{\pm}16.5$ and $87.72{\pm}11.7$ for the states of pre-operation, induction of anesthesia, operation, awaked and post-operation, respectively. The results show that while the depth of anesthesia was evaluated, more accurate information can be provided for anesthetician.

  • Cerebral palsy is a non-progressive disorder resulting from central nervous system damage caused by multiple factors. Almost all cerebral palsy patients have a movement disorder that makes dental treatment difficult. Oral hygiene management is difficult and the risks for periodontitis, dental caries and loss of multiple teeth are high. Placement of dental implants for multiple missing teeth in cerebral palsy patients needs multiple rounds of general anesthesia, and the prognosis is poor despite the expense. Therefore, making the decision to perform multiple dental implant treatments on cerebral palsy patients is difficult. A 33-year-old female patient with cerebral palsy and mental retardation was scheduled for multiple implant treatments. She underwent computed tomography (CT) under sedation and the operation of nine dental implants under general anesthesia. Implant-supported fixed prosthesis treatment was completed. During follow-up, she had the anterior incisors extracted and underwent the surgery of 3 additional dental implants, completing the prosthetic treatment. Although oral parafunctions existed due to cerebral palsy, no implant failure was observed 9 years after the first implant surgery.

  • A 2-year-old, castrated male, Scottish fold cat was referred to Veterinary Medical Teaching Hospital of Seoul National University (VMTH-SNU) for evaluation of acute bilateral blindness after general anesthesia. For dental prophylaxis in local animal hospital, general anesthesia had been induced with intravenous acepromazine and ketamine, and maintained with isoflurane after intubation. At VMTH-SNU on next day, complete blood count, electrolytes and serum chemistry values were within normal ranges. On neurologic examination, visual placing and postural reactions like as hopping, hemiwalking and wheelborrowing were reduced on right hindlimb. On ophthalmic examination, menace responses were absent on both eyes and pupillary light reflex (PLR) reduced on right eye, but other reflex and fundus were normal. Prednisolone (2 mg/kg sid for 3 days) was administrated orally and tapered. Visual placing was possible on 2nd day, and postural reactions were recovered on 4th day after dental prophylaxis. Based on the process and recovery, this case was considered as postoperative visual loss (POVL) after general anesthesia.

  • Wolff-Hirschorn syndrome is a condition that is caused by a deletion of genetic material near the end of the short (p) arm of chromosome 4. The major features of this disorder include a characteristic facial appearance, delayed growth and development, intellectual disability, and seizures. A 9-year-old girl was brought to the clinic with a chief complaint of dental examination. The child was diagnosed as WHS at Samsung medical center. The child was under Sodium valproate, Atrovastatin medication for epilepsy, hyperlipidemia and had a history of heart surgery. So prophylactic antibiotics were recommended. The child was mentally retarded and had seizure so it was difficult to manage her behavior effectively. Thus dental treatment was carried out under general anesthesia. For prompt sedation induction we used 8% sevoflurane shortly. This report presents the case of a 9-year-old girl with WHS, who has received treatment for extensive caries under general anesthesia.

  • The effectiveness of dental implants in patients with disability, who are non-compliant during treatment, is controversial because of their poor oral health. Thus, oral health-care and management in such patients is concerning. Moreover, limited information is available on prognosis after implant placement. Herein, we describe a patient with schizophrenia who underwent dental implantation under multiple inductions of general anesthesia (5 times) and required conservative treatment and tooth extraction for multiple dental caries and retained roots because of inadequate oral health-care. Postoperatively, fracture of the prosthodontics and progression of dental caries were observed, and with 3 additional inductions of general anesthesia, conservative treatment, implant surgery, and prosthesis implantation were conducted. Postoperative 12-month follow-up since the last prosthesis implantation showed successful results. For patients with schizophrenia, multiple implantation can reduce horizontal bone loss and achieve aesthetic results compared to treatment with removable prosthodontics and could serve as an alternative treatment modality.

  • 소아환자를 진료하다 보면 불안과 공포가 극도로 심하여 일반적인 행동조절법으로는 양질의 치과치료가 불가능한 상황에 자주 접하게 된다. 음성조절과 신체 속박 또는 입 가리기 등의 강압적이고 물리적 인 방법을 사용하여도 역시 치료결과가 만족스럽지 않고 이러한 경우 환자와 보호자에게 가해지는 정신적인 상해는 결코 무시할 수 없다. 따라서 행동 조절의 어려움과 치과 질환의 심각성 등으로 인해 전신마취하의 치과치료가 필요한 경우가 많으며 이 경우 전신마취는 행동조절법의 하나로 간주될 수 있다. 치과전신마취는 비용이 많이 드는 것과 적지만 있을 수 있는 부작용의 위험성을 가지고 있다. 그러나 환자의 내원횟수를 줄일 수 있고 치과치료에 대한 부정적인 행동반응을 유발하지 않아 의사와 환자의 스트레스를 줄일 수 있으며 양질의 진료가 가능하다는 점에서 장점을 갖는다. 이번 실태조사는 2000년 12월부터 2005년 4월까지 전북대학교 치과병원 소아치과에서 전신마취하에 광범위한 치과치료를 받은 200여명의 환자를 대상으로 하여 나이, 성별 등의 인적 사항, 전신마취가 필요했던 이유, 전신마취시간, 치료의 종류, 전신마취횟수 등에 관하여 조사하였다.
