  • Blood coagulation time, bleeding time, clot retraction ability, thrombocytes counts and hematological values under electroacpuncture anesthesis and medicament anesthesia, using 10 mongrel dogs were compared. The results were summarized as follows: 1. Blood coagulation time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.001). 2. Bleeding time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.01). 3. Clot retraction ability under electroacupuncture anesthesia was better than that under medicament anesthesia (p<0.01). 4. Thrombocytes counts under electroacupuncture anesthesia was more increased than that under medicament anesthesia (p<0.05). 5. Erythrocytes counts, hematocrit values, hemnglobin contents and leukocytes counts were decreased (p<0.01) under medicament anesthesia in comparison with control group, but there was no significant difference under electroacupuncture anesthesia.

  • The sleep homeostatic response significantly affects the state of anesthesia. In addition, sleep recovery may occur during anesthesia, either via a natural sleep-like process to occur or via a direct restorative effect. Little is known about the effects of isoflurane anesthesia on sleep homeostasis. We investigated whether 1) isoflurane anesthesia could provide a sleep-like process, and 2) the depth of anesthesia could differently affect the post-anesthesia sleep response. Nine rats were treated for 2 hours with $ad$ $libitum$ sleep (Control), sleep deprivation (SD), and isoflurane anesthesia with delta-wave- predominant state (ISO-1) or burst suppression pattern-predominant state (ISO-2) with at least a 1-week interval. Electroencephalogram and electromyogram were recorded and sleep-wake architecture was evaluated for 4 hours after each treatment. In the post-treatment period, the duration of transition to slow-wave-sleep decreased but slow wave sleep (SWS) increased in the SD group, but no sleep stages were significantly changed in ISO-1 and ISO-2 groups compared to Control. Different levels of anesthesia did not significantly affect the post-anesthesia sleep responses, but the deep level of anesthesia significantly delayed the latency to sleep compared to Control. The present results indicate that a natural sleep-like process likely occurs during isoflurane anesthesia and that the post-anesthesia sleep response occurs irrespective to the level of anesthesia.

  • Intravenous anesthesia was compared with inhalation anesthesia in 20 patients of oral and maxillofacial surgery. The patients were randomly assigned to two treatment groups so that 20 patients were injected ketamine and propofol and 20 patients were administered enflurane. The hemodynamic responses of patients and recovery profile of the two groups were compared. Intravenous anesthesia group awoke significantly faster than inhalation anesthesia after operation. Time to full recovery in intravenous anesthesia group was significantly shorter than that of inhalation anesthesia group. We conclude that intravenous anesthesia is a practical technique for oral and maxillofacial surgery patients and intravenous anesthesia may be more preferable because of the significant shortness of recovery time.

  • Pain control by means of local anesthesia is an intrinsic part of clinical practice in dentistry. Several studies evaluated intraligamental anesthesia using a computer-controlled anesthetic device in children. There is a need to provide a clinical guide for the use of computerized intraligamental anesthesia in children. Intraligamental anesthesia using a computer-controlled anesthetic device was found to cause significantly lower pain perception scores and lower pain-related behavior than traditional techniques. This device proven to be effective in restorative and pulp treatment in children; however, its effectiveness in primary teeth extraction is controversial. It is important to withdraw recommendations necessity of future studies concerning the side effects of computerized intraligamental anesthesia in children. The present study aims to review different clinical aspects of computerized intraligamental anesthesia in children along with the side-effects, type of local anesthesia and postoperative pain of this technique. This study provides dentists with a clinical guide for the use of computerized intraligamental anesthesia.

  • The present study was carried out to compare xylazine(2.2mg/kg, IV), xylazine/acepromazine(1.1mg/kg. IV : 0.2mg/kg, IV) and xylazine/diazepam(1.1mg/kg, IV :1.0mg/kg, IV) anesthesia, to determine useful method out of three kinds of anesthesia and tr evaluate this selected method at hypovolemic state. In xylazine, kylazine/acepromazine and kylazine/diazepam anesthesia, the heart rate was increases after administration of atropine until 10minutes after administration of anesthetics and then decreased gradually in all types of anesthesia. The respiratory rate was decreased after administration of anesthetics in all types of anesthesia. The body temperature was rarely changed in xyiazine/acepromazine and xylazine/diazepam anesthesia, but decreased continuously in xylazine anesthesia. In xylazine and kylazine/acepromazine anesthesia the pedal and corneal reflex were not disappeared completely, but reactions to pin pricking were disappeared. In xylazine/diazepam anesthesia their reflex and reactions were disappeared together. The time from head-up to standing was shortest(32.00min) in kylazine/diazepam anesthesia in comparision with xylazine and kylazine/acepromazine anesthesia. In xylazine/diazepam anesthesia, the heart rates in hypovolemic dogs were decreased soon after administration of anesthetics but recovered immediately. The changes in systolic and diastolic blood pressure in hypovolemic dogs revealed similar trends to their changes in normal dogs after administration of anesthetics. It is considered that rylazine/diazepam anesthesia is one of the useful anesthetic methods in healthy dogs and also in hypovolemic dogs.

  • Certain oral surgery can be performed safely under monitored anesthesia care (MAC) with local anesthesia. Several drugs, such as propofol, benzodiazepine, and opioids have been used for MAC either alone or in combination. Benzodiazepine may cause excessive sedation and confusion, and propofol can also result in disorientation and excessive sedation. Low dose propofol anesthesia with the concomitant use of dexmedetomidine is an effective technique for MAC in patients who are scheduled for intraoral surgery.

  • The purpose of this study was to identify the needs which were perceived by patients who were received spinal anesthesia for surgery. The subjects consisted of 50 adult patients who were admitted to 2 university hospitals and 2 general hospitals in Pusan city and 1 general hospital in Koje City for surgery under spinal anesthesia. Thirty eight percent of subjects received information about anesthesia before the operation. The instrument for this study was developed by the researcher based on literature and a pretest. Data were collected from December 10, 1999 to February 10, 2000 and were analyzed by content analysis. The results were that there were 533 meaningful statements in the needs of spinal anesthesia patients. The needs of spinal anesthesia patients had 51 items (preoperation (6), induction of anesthesia(5), intraoperation (27), postoperation(13)) and 6 categories (information, emotional welfare, physical welfare, post anesthetic management, control of physical environment, humane treatment). From the results, it can be concluded that: 1. In the pre-operation period, we have to explain anesthesia procedures, adequate position of anesthesia, duration before anesthesia wears off and sensation of paralysis. We have to supply emotional support to relieve anxiety because of anesthesia. 2. In induction of anesthesia, we have to support patient's position for anesthesia, and relieve anxiety so that patients participate in induction of anesthesia well. 3. In intra-operative period, we have to check the level of anesthesia, and keep up a comfortable position for operation and care for physical discomfort such as thirst, nausea, vomiting, dyspnea and to maintain body temperature of the patient. Since the patient is conscious, we have to communicate with the patient to relieve anxiety, maintain privacy, inform the patient of the process of the operation and encourage the surgeon to explain the outcome of the operation. The operating team needs the careful about what they say and to place the instrument well. We have to ventilate the room air and reduce noise. 4. In the post-operative period, we have to explain the purpose and duration of bed rest, complications of anesthesia and care for physical discomfort such as pain, dysuria, headache, backache. Also we have to maintain body temperature of the patient and maintain privacy.

  • Local anesthesia is administered to control pain, but it may induce fear and anxiety. Root planing is a non-surgical periodontal therapy; however, when it is performed in an extensive manner, some tissue removal is inevitable. Notably, this removal may be so painful that local anesthesia is required to be administered to the area scheduled for the treatment. Although patients tend to accept root planing easily, they frequently express a fear of local anesthesia. Intraosseous anesthesia (IA) is an intraosseous injection technique, whereby local anesthetic is injected into the cancellous bone supporting the teeth. A computer-controlled IA system (CIAS) exhibits multiple benefits, such as less painful anesthesia, reduced soft tissue numbness, and the provision of palatal or lingual, as well as buccal, anesthesia via single needle penetration. In this report, we present two cases of root planing that were performed under local anesthesia, using a CIAS.

  • Most elective cesarean sections are conducted under spinal anesthesia. Regional anesthesia has become the preferred technique, because general anesthesia is associated with a greater risk of maternal morbidity and mortality. In patients without absolute contraindication, spinal anesthesia is avoided, when procedural difficulty is increased by severe spinal deformity. A 41-year-old female patient was 33 weeks into pregnancy. Her height and weight were 145 cm and 45 kg. The patient was planned for emergency cesarean section, due to cephalopelvic disproportion. Spinal anesthesia was planned since she was suffering from Duchenne's muscular dystrophy, and had risks of respiratory failure and prolonged mechanical ventilation after general anesthesia. However, the patient also had severe kyphoscoliosis, maybe due to Duchenne's muscular dystrophy. We are reporting a successful spinal anesthesia using real-time ultrasound guidance, for cesarean section in this obstetric patient with severe kyphoscoliosis.

  • Anesthesia, which started being used to remove pain during surgery, has become itself one of the major concerns to be considered during surgery. While actual anesthesia is being performed, patients tend to have unpleasant experiences, due to wakening that accompanies pain, or wakening that does not accompany pain. Since this awakening during anesthesia is a most unpleasant experience in a patient's life, evaluating the depth of anesthesia during surgery is essential for patients to avoid this experience. Although there has been much effort on the understanding and measurement of the depth of anesthesia, while various researches were performed on the need of anesthesia, the development of an indicator that could objectively evaluate the depth of anesthesia, other than by using the patient's vital signs, is still inadequate. Therefore, this study was to develop an objective indicator by using EEG and ECG, which are essentially measured during the surgery, to evaluate the depth of anesthesia. The experiment was performed by taking patients who require a relatively short operation time, and general inhalation anesthetics among surgical patients in obstetrics and gynecology as the subjects of experiment, to measure the EEG and ECG signals of patients under anesthetics. The result showed that SEF using EEG and LF, HF using ECG signal and correlation dimension analysis parameter were valuable parameters that could measure the depth of anesthesia, by the stage of anesthesia.
