  • Purpose: This research was conducted to evaluate, analyze, and determine the limitation of the anesthesia that is used in there covery room in order to provide the foundation for developing the effectiveness of it. Method: There covery records of this study were collected from 41 hospitals in Seoul, Kyung Kii-Do, and Inchon province. The post anesthetic recovery records consisted of the evaluation of type, evaluative items, frequency, time, score and $SaO_2$. These records were collected from September to December of 2005. Results: The most commonly used post anesthetic evaluation tool was Alderete Score, which was used in 73% of hospitals. The second was Aldrete Score with $SaO_2$(17%). Also, 5% of the hospitals used the modified AS form. There were 2.5% of the hospitals applying the adult and child in the evaluation separately. Also, the last 2.5% of the hospitals did not use AS but measured BP, pulse, respiration, temperature, and $SaO_2$ with observing nausea, vomiting, urinary retention, backache, laryngitis, shock, and neurologic assessment. Conclusion: It is necessary to develop a post-anesthetic recovery evaluation tool including the application of $SaO_2$, so that the early-diagnosis of hypoxia can be possible. In addition, it is necessary to develop a post- anesthetic recovery evaluating method that can distinguish a difference between adults and children.

  • Recently, the number of diabetic patients have been increased with westernized living way and meal habitation. The regulation of blood sugar concentration is very important for diabetic patients to keep homeostasis and, to prevent acute or chronic complications. Epinephrine combined with lidocaine is used in dental clinic extensively. And epinephrine combined with lidocaine also effects on decreasing the blood leakage volume by constricting micro vessle and arteriole. But, So far there are few researches about the effect of epinephrine contained in dental local anesthetic agent on the blood sugar of diabetes during minor oral surgery. The purpose of this study was intended to investigate whether epinephrine which combined with dental local anesthetics influence body glucose level in diabetes patients by glucose monitoring. The subject of this study were 38 diabetic patients and 38 normal adults, each patient was checked body glucose after a meal 2 hours later with resting state, and injection 1:100000 epinephrine with dental lidocaine 54 ml or lidocaine 54 ml only. And then the body glucose level was checked 5 minutes and 30 minutes after injection. The results were analyzed by two way ANOVA test (p<0.05). The results were as follows: In the experimental group 1, the mean of the blood sugar level was 180.3 mg/dl before an anesthetic injection, 182.8 mg/dl after 5minutes of the anesthetic injection and 182.2 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the experimental group 2, the mean of the blood sugar level was 237 mg/dl before an anesthetic injection, 234.5 mg/dl after 5minutes of the anesthetic injection and 231.8 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 1, the mean of the blood sugar level was 117.6 mg/dl before an anesthetic injection, 119.1 mg/dl after 5minutes of the anesthetic injection and 129.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 2, the mean of the blood sugar level was 104.2 mg/dl before an anesthetic injection, 102 mg/dl after 5minutes of the anesthetic injection and 105.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05).

  • Myasthenia gravis is usually defined as a state of abnormal fatigability. The cause of myasthenia gravis is not known. Several disorders tend to occur more frequently in patients with myasthenia gravis, such as hyperthyroidism or other thyroidal disorder. Anesthetic experience with thymectomies for two patients with myasthenia gravis has been reported. Both of them tolerated the surgical procedures under endoteracheal Nitrous oxide-Oxygen-Halothane anesthesia well. Diagnosis and clinical features including choice of preanesthetic medication, anesthetic agents, techniques and of neuromuscular blocking agents for myasthenic patients have been discussed. Paramount importance of rigid attention to ventilation, the maintenance of a patent airway and the removal of secretions whenever necessary for the patient safety throughout operative and postoperative period has been stressed.

  • This study was carried out to investigate the effects of intravenous drip with ketamine hydrochloride and its application for control depth and maintenance of anesthesia in dogs. Changes of blood pressure, vital signs, blood gas and anesthetic state were observed in this study. The obtained were summerized as follows ; 1. Changes of blood pressure and heart rate after intravenous drip anesthesia with ketamine hydrochloride were observed with significant increase in all group ; group II (0.135m81k9/min), group III (0.269mg/kg/min) and group IV(0.538mg/kg/min). These conditions were maintained unchangeably until 160 minutes after administration in all group. This may be indicated that there were no side effects on account of ketamine accumulation. 2. There were irregular respiration, pain reflex, Jaw tone reflex and vomition probability in the anesthetic conditions of group II The anesthetic conditions of group III were rarely shown as mentioned above. Awakening time and recovery time of group H were more prolonged 21 minutes and 27 minutes respectively than those of group III. These experimental data suggested that the optimal dosage of intravenous drip anesthesia of ketamine Hcl was 0.269mg/kg/min.

  • Objectives. To identify the optimal pharmacological method of preparing patients for nasal endoscopy. Methods. Twenty healthy volunteers were enrolled in this prospective, randomized, double-blind study. Four types of medications were applied in their nostrils with binary combinations of spray bottles on four different days in a random order: placebo (normal saline [NS]+NS), decongestant (NS+oxymetazoline), anesthetic (NS+lidocaine), and decongestant plus anesthetic (oxymetazoline+lidocaine). Rigid nasal endoscopy was performed 10 minutes after spray application. The volunteers evaluated the discomfort caused by each spray application, and nasal pain scores due to the passage of the endoscope. The physicians quantified nasal decongestion using a visual analogue scale. Endoscopy duration as well as pulse and mean blood pressure (MBP) before spray application, 10 minutes after the application, and immediately after endoscopic examination were also recorded. Results. The discomfort caused by lidocaine was significantly higher than that caused by the other sprays (P<0.001). The lowest pain score related to endoscopy was obtained for oxymetazoline+lidocaine (P<0.001). Nasal decongestion was best achieved with NS+oxymetazoline (P<0.001). Endoscopy duration was the shortest for oxymetazoline+lidocaine (P<0.05). Statistically significant MBP changes were only seen with the application of NS+oxymetazoline (P<0.05). However, neither MBP nor pulse rate change was significant clinically. Conclusion. Application of decongestant and anesthetic sprays together seems to be the best method of pharmacological preparation of patients for nasal endoscopy.

  • Background: Patients with intellectual disability (ID) often require general anesthesia during oral procedures. Anesthetic depth monitoring in these patients can be difficult due to their already altered mental state prior to anesthesia. In this study, the utility of electroencephalographic indexes to reflect anesthetic depth was evaluated in pediatric patients with ID. Methods: Seventeen patients (mean age, $9.6{\pm}2.9years$) scheduled for dental procedures were enrolled in this study. After anesthesia induction with propofol or sevoflurane, a bilateral sensor was placed on the patient's forehead and the bispectral index (BIS) was recorded. Anesthesia was maintained with sevoflurane, which was adjusted according to the clinical signs by an anesthesiologist blinded to the BIS value. The index performance was accessed by correlation (with the end-tidal sevoflurane [EtSevo] concentration) and prediction probability (with a clinical scale of anesthesia). The asymmetry of the electroencephalogram between the left and right sides was also analyzed. Results: The BIS had good correlation and prediction probabilities (above 0.5) in the majority of patients; however, BIS was not correlated with EtSevo or the clinical scale of anesthesia in patients with Lennox-Gastaut, West syndrome, cerebral palsy, and epilepsy. BIS showed better correlations than SEF95 and TP. No significant differences were observed between the left- and right-side indexes. Conclusion: BIS may be able to reflect sevoflurane anesthetic depth in patients with some types of ID; however, more research is required to better define the neurological conditions and/or degrees of disability that may allow anesthesiologists to use the BIS.

  • The aim of the present study was to evaluate the influences of epinephrine and pain on the changes of blood pressure and pulse rates in mandibular 3rd molar extraction. A total of 80 patients(aged between 10 and 30) without systemically compromised conditions were selected and divided into two groups(I, II). 2% lidocaine with 1:100,000 epinephrine was administered in group I (male 20, female 20), and 2% lidocaine without epinephrine was administered in group II (male 20, female 20). Systolic blood pressure and pulse rates were checked by a digital monitor during the pre-local anesthesia state(stage 1), 5 minute later in the post-local anesthesia state(stage 2), the extraction state(during odontectomy, stage 3), and during the post-suture state(stage 4). The measurement of pain perceived by patients was made using a three-point visual analog scale. The results suggest that local anesthetic with epinephrine is better at decreasing pain preventing the severe elevation of systolic blood pressure than local anesthetic without epinephrine. However, these results should be confirmed by additional studies on cardiac patients.
