The anesthetic effects by dosages of Tiletamlne-Zolazepam in the dogs were investigated and then the optimal dosages for the operation of patients were suggested. 1. In groups of T+Z 20, 10 and 5 mg/kg administration, anesthetic periods are 180~300, 33~47 and 40~50 minutes, respectively and complete recovery from anesthesia was shorted with taking 53~72 minutes in the group of 5 mg/kg administration. 2. Reflex responses to eyelids, cornea and pharyngolarynx were maintained but pedal reflexes became considerably sluggish 3. It showed tachycardias on ECG but there were no specific dysrhythmias. On EEG, it showed low voltage-fast waves before anesthesia, high voltage-fast waves in induction stage, low voltage-slow waves in anesthetic stage and high voltage-fast waves again in recovery stage. 4. Surgical procedures could be performed satisfactorily in 6 cases of the 10 mg/kg administration group, but in 3 of 5 cases of 5 mg/kg administration group it could be completed after additional administration. 5. In conclusion, it was considered desirable for anesthetizing dogs that for healthy cases T+Z at the level of 10 mg/kg B.W. was administered, and for poor risk patients, 5 mg/kg B.W., followed by an additional administration in unsatisfied cases.

Background: The limited studies on the effect of buffering on the clinical efficacy of articaine have reported controversial results. The purpose of this study was to clinically compare the pain of injection, anesthetic success, onset, and duration of pulpal anesthesia of buffered 4% articaine with epinephrine 1:100000 versus a non-buffered 4% articaine with epinephrine 1:100000 formulation for buccal infiltration of the mandibular first molar. Methods: Sixty-three volunteers were enrolled in the study. All volunteers received two injections consisting of a single mandibular first molar buccal infiltration with 1.8 ml of 4% articaine with epinephrine 1:100000 and 1.8 ml of 4% articaine with epinephrine 1:100000 buffered with 8.4% sodium bicarbonate. The infiltrations were applied in two separate appointments spaced at least one week apart. After injection of the anesthetic solution at the examined site, the first molar was pulp-tested every 2 min for the next 60 min. Results: Successful pulpal anesthesia was recorded in 69.8% of cases using non-buffered articaine solution and 76.2% of cases using buffered articaine solution, with no significant difference between the formulations (P = 0.219). The mean time of anesthesia onset for the volunteers with successful anesthetic outcome in both formulations (n = 43) was 6.6 ± 1.6 min for the non-buffered articaine solution and 4.5 ± 1.6 min for the buffered solution, which differed significantly (P = 0.001). In the same volunteers, the mean duration of pulpal anesthesia was 28.4 ± 7.1 min for non-buffered articaine solution and 30.2 ± 8.5 min for buffered articaine solution, with no significant difference between the formulations (P = 0.231). Considering the pain of injection, regardless of the anesthetic success, the mean values of VAS were 11.3 ± 8.2 mm for the non-buffered articaine solution and 7.8 ±6.5 mm for the buffered articaine solution, which differed significantly (P = 0.001 < 0.05). Conclusion: According to the present study, 4% articaine with epinephrine can benefit from buffering and provide better anesthetic behavior, with improved onset and less pain during injection.

Lidocaine, a local anesthetic commonly used in dental treatments, is capable of causing allergies or adverse effects similar to allergic reactions. However, the frequency of such occurrences in actual clinical settings is very rare, and even clinical tests on patients with known allergies to local anesthetics may often show negative results. When adverse effects, such as allergy to lidocaine, are involved, patients can be treated by testing other local anesthetics and choosing a local anesthetic without any adverse effects, or by performing dental treatment under general anesthesia in cases in which no local anesthetic without adverse effects is available. Along with a literature review, the authors of the present study report on two cases of patients who tested positive on allergy skin tests for lidocaine and bupivacaine and subsequently underwent successful dental treatments with either general anesthesia or a different local anesthetic.

Although rare, complications can occur with anesthetic procedures. The posterior superior alveolar nerve (PSAN) block anesthetic technique has a high success rate, but positive aspiration can cause bruising, transient diplopia, blurred vision, and temporary blindness in approximately 3% cases. When edema occurs, it is occasionally massive, especially in the infratemporal fossa, and the resulting hematoma is usually unsightly. A 20-year-old woman presented with massive edema followed by hematoma in the upper right jaw immediately after PSAN block administration, which subsequently spread to the oral mucosa. The patient did not report any complications during the anesthetic procedure. However, after the injection was administered, the patient experienced anesthetic sensations, which rapidly evolved to facial edema. There was mild pain, but without intraoral or extraoral bleeding. The patient was prescribed medicines and instructed to perform contrast therapy. Although hematomas and edema are rare, they are difficult to prevent. The choice of local anesthetic and appropriate application of the anesthetic technique can minimize their occurrence.

Wolf-Hirschhorn syndrome is a rare hereditary disease that results from a 4p chromosome deletion. Patients with this syndrome are characterized by craniofacial dysgenesis, seizures, growth delay, intellectual disability, and congenital heart disease. Although several cases have been reported, very little information is available on anesthetic management for patients with Wolf-Hirschhorn syndrome. We encountered a case requiring anesthetic management for a 2-year-old girl with Wolf-Hirschhorn syndrome. The selection of an appropriately sized tracheal tube and maintaining intraoperatively stable hemodynamics might be critical problems for anesthetic management. In patients with short stature, the tracheal tube size may differ from what may be predicted based on age. The appropriate size ( internal diameter ) of tracheal tubes for children has been investigated. Congenital heart disease is frequently associated with Wolf-Hirschhorn syndrome. Depending on the degree and type of heart disease, careful monitoring of hemodynamics is important.

가쪽날개근은 턱의 기능을 수행하는데 기본적인 저작근 중의 하나이다. 이 근육은 저작계의 심부에 위치하기 때문에 손가락을 이용한 촉진검사가 어려우며 그 결과도 신뢰할 만하지 못하다. 이러한 이유로 임상의에게 가쪽날개근에 이환된 근육통 질환을 진단하는 것은 쉽지 않은 문제이다. 근육내 국소마취 주사는 통증의 근원지를 감별하는 목적으로서 가쪽날개근을 검사하는 효과적인 방법이 될 수 있다. 또한 근육통을 즉각적으로 제거함으로써 근육을 전체 길이만큼 신장하는데 도움을 줄 수 있다. 저자들은 근육내 국소마취 주사를 이용하여 가쪽날개근의 근육통을 성공적으로 진단하고 치료한 두 증례를 보고하고자 한다.

Background: The aim of this study was to analyze outpatient anesthesia for dental treatment in handicapped patients with behavior disorder in order to use data for carrying out better and safe anesthetic management. Methods: The data were drawn from the 100 patients with behavior disorder who visited CNUDH dental clinic for disabled based on anesthesia record to investigate patient's systemic condition, cooperative level, anesthesia method according to patients cooperation, and side effects after recovery time. Results: Mental retardation (58%) is the most reason to choose general anesthesia. The methods of induction according to cooperative level are intravenous propofol injection in 22 cases and inhalation of sevoflurane in 78 cases. Induction time of anesthesia were within 10 seconds in cases of propofol induction and average $48.8{\pm}18.5$ seconds in cases of inhalation induction. The time spent on dental treatment was average $3.2{\pm}1.1$ hours. After the end of treatment, average time to move from unit chair to recovery bed, to recliner, and to discharge from hospital are $10.4{\pm}5.1$, $36.9{\pm}17.1$ and $72.4{\pm}16.0$ minutes, respectively. During recovery, there are nausea with 9%, vomiting with 4%, dizziness with 2%, finger injury with 1%. Conclusions: This study showed our successful anesthetic outcomes without any severe side effects or complications. Through this study, it will be used for safe anesthetic management as useful reference data.

Background: To evaluate the results of various types of radiofrequency ablation (RFA) treatment of renal tumors in patients with excessive anesthetic and surgical risk. Materials and Methods: Data for RFA performed in in high risk patients were retrospectively evaluated. Other RFA applications in patients with no anesthetic and/or surgical risk were excluded. RFA was by ultrasound or CT guided percutaneous (USG/CT-PRFA) and retroperitoneally or transperitoneally laparoscopic (R/T-LRFA) techniques under general or local anethesia. Follow-up data of enhanced CT or MRI after 1, 3 and 6 months were analysed for twelve RFA applications. Results: The RFA applications included 4 (40%) left-sided, 5 (50%) right-sided and 1 (10%) bilaterally RFA (simultaneously 1 right and 2 left). The localizations of tumors were 2 (16.6%) upper, 5 (41.6%) mid and 5 (41.6%) lower pole. The RFA applications included 9 (75%) USG-PRFA, 1 (8.3%) CT-PRFA, 1 (8.3%) T-LRFA and 1 (8.3%) R-LRFA. The mean age was $65.3{\pm}8.5$ (52-76) years. The mean tumor size was $29.6{\pm}6.08$ (15-40) mm. No complications related to the RFA were encountered in any of the cases. Failure (residual tumour) was determined in 8.3% (1/12) of USG-RFA application. The success rate was thus 91.7% (11/12). Other 1st, 3rd and 6th months follow-up data revealed no residua and recurrence. Conclusions: RFA application appears to be safe as a less invasive and effective treatment modality in selected cases of small renal tumors in individuals with excessive anesthetic and also surgical risk.
