  • When routine behavior control is impossible, midazolam is often used for sedation, because it has wide margin of safety, relatively few side-effects and multiple route of administration. Although intramuscular administration of all administration route is frequently used, it is a major source of anxiety, discomfort, and trauma in children. To the contrary, oral administration of midazolam is easily administered and accepted by children. But, it's therapeutic drug concentration has not been established. The purpose of this study was to compare sedation effect and physiologic parameter of oral midazolam which palliate demerits of intramuscular administration in sedating young pediatric patients with intramuscular midazolam Twelve negative children, mean age 62.5 months, who needed at least two separate restorative visits, requiring local anesthesia participated in this study On every visit, one of the following 2 different sedative regimen was given : (1) 0.30mg/kg midazolam by intramuscular administration (2) 0.75mg/kg by oral administration. Physiologic parameter(oxygen saturation, heart rate) was recorded by ten procedure and behavior was videotaped and rated using Ohio State University Behavior Rating Scale and Automated Counting System by one investigator, blind to administration route The analyzed sedative effect of oral midazolam resulted in good sedative effect, comparing to intramuscular route, And there is no statistically difference between oral and intramuscular administration of midazolam (p>0.05).

  • The purpose of this study was to compare the sedative effect of three routes of administration - intramuscular, intranasal drop-in, intranasal spray - with midazolam. The twenty two uncooperative children from 23 months to 76 months who required at least three dental appointment. Each patient was assigned randomly to receive intramuscular(Group I, 0.15mg/kg), intranasal drop-in(Group II, 0.20mg/kg), intranasal spray(Group III, 0.20mg/kg) administration at each visit. Sleep, crying, movement, and overall behavior response were evaluated, and the sedative effects were evaluated by Houpt's rating scale In order to monitor the sedated patients, pulse rate and peripheral oxygen saturation were measured by pulse oximeter during treatment procedures. The results were as follows 1. Pulse rate and peripheral oxygen saturation were stable through all the treatment procedures, and there were no statistically significant differences among three routes of administration(P>0.05). 2. The effect on sleep was, III, II, I, in order, III group was the most effective through all the treatment procedures, except rubber-dam placement and filling phase (P<0.0001). 3. The effects on crying, movement, overall behavior were II, III, I, in order, II group was the most effective through all treatment procedures(P<0.0001).

  • Irritation fibroma is a common hyperplastic lesion of the oral mucosa that can occur in response to chronic irritation or trauma. This report presents an unusual case of irritation fibroma associated with ectopic eruption of the maxillary left central incisor in a patient with Angelman syndrome. Considering the patient's medical history and cooperative ability, excisional biopsy under intramuscular sedation using midazolam was performed. The patient exhibited successful healing without lesion recurrence. It is important to perform histopathological examination followed by excisional biopsy, because other benign or malignant tumors may mimic the clinical appearance of an irritation fibroma.

  • Many drugs are administered intramuscularly to immobilize and anesthetize dogs. There are many established intramuscular (IM) anesthetic combinations for dogs; however, little information is available on the effects of a xylazinediazepam-ketamine (XDK) combination. The purpose of this study was to investigate the anesthetic effects of the XDK combination in dogs. Twelve adult mixed bred dogs were used. All dogs were anesthetized with an IM injection of diazepam (0.5 mg/kg) and xylazine (1.1 mg/kg) with low-dose ketamine (5 mg/kg; group 1) or high-dose ketamine (10 mg/kg; group 2) in one syringe. After administration of the test dose, the animals were positioned in a right lateral recumbency, and analgesia and cardiopulmonary data were collected and recorded. The duration of anesthesia in group 2 was significantly longer than that of group 1 (mean [sd] 68.0 [7.6] v 51.3 [2.7] minutes). Blood pressure increased significantly after XDK administration in both groups, and $S_aO_2$ levels decreased significantly from baseline at 10, 20, and 30 minutes in both groups. XDK administration produced satisfactory sedation and analgesia in all dogs. In conclusion, intramuscular administration of xylazine-diazepam-ketamine combination at a doses of 1.1 mg/kg xylazine, 0.5 mg/kg diazepam, and 5 or 10 mg/kg ketamine appeared to be effective short duration anesthetic protocols in dogs.

  • Intravenous sedation have many advantages of rapid onset and recovery, ability of control sedation levels and duration through titration. Midazolam is most commonly used intravenous medication for sedation in pediatrics, endoscopy, oncologic procedures and so on. But in dentistry, midazolam intravenous sedation is usually for adult, and there are few reports for children. Todays, children who need sedation become more and older, intravenous sedation technique is going a matter of concern in pediatric dentistry. The purpose of this paper is to evaluate the efficacy of sedation and clinical success for different initial dosage of midazolam in intravenous sedation for pediatric dental patients. 16 healthy children (male 10, female 6), mean age $54.7{\pm}10.7$ months, who needed at least two separate treatment visits requiring local anesthesia were chosen for this study. Every children were taken 0.3mg/kg, maximum 5mg of midazolam by intramuscular route, and then 30~50% $N_2O-O_2$ for 10 minutes was given. On every visits, one of the following 2 different initial dosage was given by intravenous route : (1) Group I : 0.1mg/kg Midazolam (2) Group II : 0.2mg/kg Midazolam. Additional dosage was half of the first dose. Physiologic parameters (oxygen saturation, heart rate, respiratory rate, end-tidal carbon dioxide pressure) was recorded by ten procedure steps. Behavior was videotaped and rated using Ohio State University Behavioral Rating Scale and Automated Counting System by one investigator, blind to administered dosage. After the treatment, operator evaluated the clinical success. Physiologic parameters were stable and within normal range during treatment in both groups. The analyzed sedative effect, in behavioral evaluation, ratio of favorable Quiet was higher in group II, and clinical success rate of group II was better than group I. Induction time was rapid in group II, and recovery time was rapid in group I. And there was no statistically difference between two groups in every results.

  • Cnidii Rhizoma (CR) was subjected to extraction with 70% methanol and tested to determine whether it has anxiolytic activity in mouse by employing staircase and rotarod tests. In addition, to understand the mechanism of anxiolytic action, CR, picrotoxin, yohimbine, isoniazid and strychnine were utilized to deliniate the potential involvement of GABA and glycine receptors in the action of Cnidii Rhizoma. To gain insights into the safety of Cnidii Rhizoma extract, behavioral and MTT tests were carried out. The results were obtained as follows: 1. CR extract had little effect on climbing numbers in the stair case test. 2. CR extract had considerable anti-anxiety effects as evidenced by the reduction of rearing numbers in the stair case test. 3. CR extract had little effect on muscle relaxation. 4. Anxiolytic actions of CR extract appeared to be mediated by glycine receptor activation. 5. Cytotoxicity in the neuronal cell was not observed and no strange behaviors were found. In short, these results indicate that CR extract has the ability to exert anxiolytic activity, possibly by activating glycine receptor with little side effects in mouse.

  • The purpose of this study was to determine the antagonistic effects of yohimbine on sedation induced in dogs with medetomidine. Six mixed breed dogs were repeatedly used at a 2 weeks withdrawal time in this study. The dogs received $40\;{\mu}g/kg$ of medetomidine followed 15 minutes later by 0.2 ml/kg saline solution (group M) or 0.11 mg/kg yohimbine (group MY). All the dogs were examined before and 5, 15, 30, 45, 60, 75, 90, 120 and 150 minutes after the injection of medetomidine, and the induction and recovery times, vital signs, blood biochemistry and anesthetic quality were recorded. There were significant differences in the recovery of anesthesia between the groups. In both groups the heart rate decreased rapidly down to five minutes after the administration of medetomidine. The activity of ALT, AST and the protein concentration did not change significantly in either group and there was no significant difference between them at any time. Response to noise, muscle tone and analgesic score in the MY group at 30 minutes were significantly lower than those of the M group. When recovering from anesthesia, the dogs treated with yohimbine took less time to achieve sternal recumbency and less time to be able to stand and walk. It was concluded that yohimbine reversed effectively medetomidine sedation in dogs.

  • This prospective study aimed to assess the efficacy of dexamethasone to prevent xylazine induced emesis in dogs. The antiemetic effect of graded, single high-dose intravenous dexamethasone against xylazine hydrochloride was studied. Clinically healthy mixed breed dogs that weighed $ 4.64\pm1.25kg$ were used in this study. Food and water were given 3 hours before the experiment. Venous blood specimens were collected from all experimental animals for hema-tological and blood chemical test pre- and post-experiment. Twenty-eight experimental animals were randomly divided into 4 groups; the group treated with 0.2ml/kg of normal saline (Control group), the groups treated with 1mg/kg (D1 group), 2mg/kg (D2 group) and 4 mg/kg of dexamethasone (D4 group). Three doses of the dexamethasone or normal saline was administered intravenousely to each group and after 5 minutes, xylazine (2.2 mg/kg) was administered intramuscularly. The time until onset of the first emetic episode and rate of emesis were investigated. At the same time, the extent of sedation was scored subjectively 5, 15, 30 and 60 minutes after injection of xylazine hydrochloride using Visual Sedation Score. The time until onset of the first emetic episode was $203.25\pm11.35$ sec in Control group, $187.33\pm48.0l$ sec in D1 group and 218.33± 13.58 sec in D2 group. The rate of xylazine induced emesis were $57\%$ in Control group and $43\%$ in D1 and D2 group respectively. On the other hand, any emetic episodes were not observed in 04 group. At extent of sedation score, all experimental animals especially including the animals in D1 group were highly sedated at 15 minutes after administration of xylazine hydrochloride. Hematological and blood chemical values showed normal ranges pre- and post-experiment. We concluded that prior treatment with 4 mg/kg of dexamethasone hardly caused xylazine-induced emesis without disturbing the sedative effect of xylazine in dogs.

  • Tidal volume by sevoflurane in small amounts is stable due to the increase in the breathing rate. But alveolus ventilation decreases due to sevoflurane as the degree of sedation increases; this ultimately causes $PaCO_2$ to rise. The occurrence of suppression of breath increases the risk of severe hypoxia and hypercapnia in deeply sedated patients with disabilities. Sevoflurane inhalation anesthesia has a number of risks and may have unexpected problems with hemodynamic changes depending on the underlying state of the body. This study was conducted to examine the stability of internal acid-base system caused by respiratory depression occurring when patients with disabilities are induced by sevoflurane. Anesthetic induction was carried out by placing a mask on top of the patient's face and through voluntary breathing with 4 vol% of sevoflurane, 4 L/min of nitrous oxide, and 4 L/min of oxygen. After the patient's loss of consciousness and muscle relaxation, IV line was inserted by an expert and intravenous blood gas was analyzed by extracting blood from vein. In a deeply sedated state, the average amount of pH of the entire patients was measured as $7.36{\pm}0.06$. The average amount of $PvCO_2$ of the entire patients was measured as $48.8{\pm}8.50mmHg$. The average amount of $HCO_3{^-}$ of the entire patients was measured as $27.2{\pm}3.0mmol/L$. In conclusion, in dental treatment of patients with disabilities, the internal acid base response to inhalation sedation using sevoflurane is relatively stable.
