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.

Intravenous anesthesia was compared with inhalation anesthesia in 20 patients of oral and maxillofacial surgery. The patients were randomly assigned to study in two treatment groups. 20 patients were injected ketamine and propofol. 20 patients were administered Enflurane. The respond of patients consciousness and general recovery condition of the two groups were compared. Intravenous anesthesia group were awake significantly faster without complications such as nause, vomiting, and agitation after operation than inhalation anesthesia group. Full recovery time of intravenous anesthesia group was significantly 3 times less than inhalation anesthesia group. The authors conclude that intravenous anesthesia is a practical technique for oral and maxillofacial surgery patients undergoing and may be preferable to intravenous anesthesia because of the significantly short of recovery time without complications.

General anesthesia or sedation is an essential for a successful dental treatment for the disabled. The aim of this study is to assess the patients who had dental management under general anesthesia or sedation at Chungnam dental clinic for the disabled, who received dental treatment under general anesthesia, sevoflurane sedation and intravenous sedation from January, 2011 to September 2012. Of the 426 patients studied, 389 patients received dental care under general anesthesia, 20 patients received dental care under sevoflurane sedation and 17 patients received dental care under intravenous sedation. The Rate of general anesthesia was higher than that of sevoflurane sedation, intravenous sedation. Sevoflurane sedation is a useful method for short time treatment such as traumatic pediatric patients. Intravenous sedation is an option for patients who had anxiety and fear such as dentally disabled patients. Sevoflurane or intravenous sedation not only gradually reduces the use of general anesthesia but also useful methods themselves for the dentally disabled.

Background: The number of patients with Alzheimer's disease is growing worldwide, and the proportion of patients requiring dental treatment under general anesthesia increases with increasing severity of the disease. However, outpatient anesthesia management for these patients involves great risks, as most patients with Alzheimer's disease are old and may show reduced cardiopulmonary functions and have cognitive disorders. Methods: This study retrospectively investigated 43 patients with Alzheimer's disease who received outpatient anesthesia for dental treatment between 2012-2017. Pre-anesthesia patient evaluation, dental treatment details, anesthetics dose, blood pressure, duration and procedure of anesthesia, and post-recovery management were analyzed and compared between patients who underwent general anesthesia or intravenous sedation. Results: Mean age of patients was about 70 years; mean duration of Alzheimer's disease since diagnosis was 6.3 years. Severity was assessed using the global deterioration scale; 62.8% of patients were in level ${\geq}6$. Mean duration of anesthesia was 178 minutes for general anesthesia and 85 minutes for intravenous sedation. Mean recovery time was 65 minutes. Eleven patients underwent intravenous sedation using propofol, and 22/32 cases involved total intravenous anesthesia using propofol and remifentanil. Anesthesia was maintained with desflurane for other patients. While maintaining anesthesia, inotropic and atropine were used for eight and four patients, respectively. No patient developed postoperative delirium. All patients were discharged without complications. Conclusion: With appropriate anesthetic management, outpatient anesthesia was successfully performed without complications for dental treatment for patients with severe Alzheimer's disease.

Anxiety and phobia in dental procedures are common deterrents for patients visiting the dental care unit. For these individuals, procedural sedation may aid in completion of dental treatments. In most cases, the patients are conscious during sedation, thereby allowing spontaneous ventilation. Intravenous sedation (IVS) is widely used during dental treatment to relieve patient anxiety. IVS is the most effective route of administration to achieve this goal, but it requires advanced training, more than that provided during undergraduate education. During IVS, rapid onset, repetitive drug administration, easy titration, and rapid recovery from sedation can be achieved. However, conscious sedation during IVS can result in deep sedation that can cause respiratory and cardiovascular depression. Therefore, the characteristics of intravenous sedatives should be known. The purpose of this review is to discuss the characteristics and usage of intravenous sedatives currently used for dental procedures.

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.

Background: Bradycardia frequently occurs in intravenous anesthesia with propofol. Additionally, the thoracic sympathetic nerves influence the heart so that the heart rate (HR) and blood pressure are expected to decrease due to this procedure. Therefore, we measured changes in HR, mean arterial pressure (MAP) and both thumb temperatures before and after thoracic sympathicotomy under total intravenous anesthesia with propofol. Methods: The subjects included 21 outpatients of ASA class I who received thoracoscopic thoracic sympathicotomy under total intravenous anesthesia. Anesthesia was induced with propofol (2 mg/kg) and vecuronium (0.1 mg/kg) and maintained with propofol-fentanyl-oxygen (100%). The surgical procedure was performed at the T3 level in the order of left sympathicotomy (LST) and right sympathicotomy (RST). Measurements of HR, MAP and both thumb temperatures were taken before induction of anesthesia, before and after LST and RST, and 1 hour after the completion of anesthesia. Additionally, the time to the beginning of a rise in temperature in both thumbs after sympathicotomy was recorded. Results: HR did not show any significant difference before or after sympathicotomy, however it decreased at 1 hour after the completion of anesthesia. MAP decreased after LST and decreased further after RST. Left thumb temperature began to increase at $45.8{\pm}10.7$ seconds after LST. Right thumb temperature initially decreased after LST and increased from $45.2{\pm}11.8$ seconds after RST. Subsequently, both increased temperatures were maintained at 1 hour after the completion of anesthesia. Conclusions: Although HR and MAP decreased, there were no severe hemodynamic changes. An increase in the thumb temperature was confirmed within 1 minute after sympathicotomy on the same side.

Ten calves were subjected to general anesthesia with ten percent chlooral hydrate solution. The drug was administered by the method of slow intravenous injection so as to have a better control over the dosage and time until deep anesthesia was attained. Although one of ten calves failed to produce anesthesia, the remainder of nine responded satisfactorily with deep anesthesia. The dosage required averaged as great as 17.5gm per calf, and the time 23 minutes. In view of these advantages indicated in the results, further studies on the use of intravenous chloral hydrate for deep anesthesia in bovine species are to be justifiable.

To compare cardiopulmonary effects and recovery between total intravenous anesthesia (TIVA) with propofol (PRO group, n=5) and volatile induction/maintenance anesthesia (VIMA) with isoflurane (ISO group, n=5), we investigated changes of heart rate, $SpO_2$, arterial pressure, rectal temperature and respiratory rate during 60 minute anesthesia and 40 minute recovery period in beagle dogs, and investigated recovery (extubation, head lift, sternal position and righting) after 60 minute anesthesia. Rectal temperature was significantly low in ISO group (p<0.05) from 10 to 100 minute. Heart rate was significantly low in ISO group (p<0.05) at 40, 50, 60 minute. Respiratory rate was significantly low in PRO group (p<0.05) at induction and 70 minute. $SpO_2$ tendency was similar. Systolic arterial pressure (SAP) was significantly low in ISO group (p<0.05) at induction and during anesthesia. Recovery was similar in two groups. We concluded that TIVA with propofol is useful in stabilizing rectal temperature and arterial pressure during anesthesia and provide fast and stable recovery.
