Objectives : The purpose of this study is to report on the improvement of respiratory function of a fascioscapulohumeral muscular dystrophy patient after receiving Korean medical treatment. Methods : This study was carried out on a 60 year-old male patient who suffered from fascioscapulohumeral muscular dystrophy. While we carried out Korean medical treatment, we observed $EtCO_2$ (end-tidal carbon dioxide), Vte (exhaled tidal volume) and PIP (peak inspiratory pressure). Results : $EtCO_2$ count decreased from 34 mmHg to 24 mmHg during the treatment period, and PIP count became stable. Vte count also did not worsen in this study. Conclusions : Based on this study, we concluded that Korean medical treatment could be effective in treating fascioscapulohumeral muscular dystrophy patients with respiratory failure.

The relationships between end-tidal partial pressure of carbon dioxide ($P_{ET}CO_2$) and arterial partial pressure of carbon dioxide ($P_aCO_2$), and between $P_{ET}CO_2$ and blood pH in isoflurane-anesthetized cinereous vultures were evaluated. Nine cinereous vultures (weighing 7.3-9.5 kg) were anesthetized via mask with isoflurane, intubated, and connected to a mechanical ventilator. By mechanical ventilator, respiratory rate was altered to achieve a $P_{ET}CO_2$ randomly selected among 30 to 35 mmHg. $P_aCO_2$ and blood pH were determined in serial arterial samples and compared with concurrent $P_{ET}CO_2$ measured with a sidestream capnography. Thirty six samples, nine cinereous vultures were tested 4 times each, were used to determine correlations coefficients between $P_aCO_2$ and $P_{ET}CO_2$, and between $P_{ET}CO_2$ and blood pH. Strong correlations were observed between $P_aCO_2$ and $P_{ET}CO_2$ (r = 0.951, P = 0.000, y = 1.679x - 30.236, $R^2=0.905$) as well as between $P_{ET}CO_2$ and blood pH (r = -0.728, P = 0.000, y = -0.024x + 8.389, $R^2=0.530$) with Pearson's correlation coefficient and simple linear regression. These results suggest that the capnography used provided a sufficiently accurate estimation of $P_aCO_2$ and blood pH. Thus, the monitoring of $P_{ET}CO_2$ can be useful method to prevent hypoventilation for cinereous vultures receiving mechanical ventilation.

Background: The aim of this study was to examine the difference of $SpO_2$, PR, $EtCO_2$, RR with submucosal injection of midazolam to oral chloral hydrate and hydroxyzine for pediatric patients Methods: Thirty two sedation cases were performed in this study. Patients were randomly classified into one group taking oral CH (60 mg/kg). hydroxyzine (1 mg/kg) and submucosal injection of midazolam (0.1 mg/kg) and the other group recieving oral CH (50 mg/kg), hydroxyzine (1 mg/kg) and submucosal injection of midazolam (0.2 mg/kg). For evaluating the depth of sedation. data including saturation percentage of oxygen ($SpO_2$), pulse rate (PR), end-tidal carbon dioxide ($EtCO_2$), respiratory rate (RR) and the behavior scale were checked every 2 minutes and were collected for only 40 minutes from the beginning of treatment and were analyzed using Two independent sample T-test. Results: Analysis showed no significant difference in the mean $SpO_2$, PR, $EtCO_2$, RR during sedation between two groups (P > 0.05). The values of $SpO_2$, PR, $EtCO_2$ and RR for both groups remained within the normal values. Conclusions: The results of this present study indicate that combination of oral CH, hydroxyzine, nitrous oxide gas inhalation and submucosal injection of midazolam improved the sedation quality without compromising safety.

Effect of supplementary intranasal midazolam on oral sedation of children The purpose of this study was to compare the cardiopulmonary parameters of two sedation regimens during dental treatment: (1) Oral chloral hydrate(CH) and hydroxyzine(HZ) with nitrous oxide-oxygen($N_2O/O_2$) inhalation(CH-HZ group); (2) Oral chloral hydrate(CH) and hydroxyzine(HZ) with nitrous oxide-oxygen($N_2O/O_2$) inhalation and supplementary intranasal(IN) midazolam administration(MIDA group). Among the patients of OO hospital who received dental treatment under sedation over the past 5 years, 44 patients were selected for each group of CH-HZ and MIDA according to their age, gender and weight. Following parameters that were recorded every 5 minutes were compared: 1) Heart rate(HR) 2) $O_2$ saturation 3) End tidal carbon dioxide concentration($EtCO_2$) 4) Respiratory rate(RR) 33 patients of Group MIDA who have complete data of 15 minutes before and after supplementary IN midazolam administration were selected. And measurements 15 minutes before and after midazolam administration in same patient were evaluated. The results were as follows: 1. Heart rate was significantly higher in MIDA group than in CH-HZ group, but it was within normal range. 2. Comparing HR, $O_2$ saturation, EtCO2, RR between before and after of supplementary IN midazolam administration in the same patient, the differences were not statistically significant.

The aim of this study was to compare the reaction of the cardiovascular system, and the anesthetic effect among 3 experimental groups, epidural administration of medetomidine as a single agent, the combination of buprenorphine and medetomidine, and the combination of fentanyl and medetomidine. Twenty one dogs were anesthetized with isoflurane and allowed to breathe spontaneously. Epidural, arterial, and venous catheters were inserted. The tip of epidural catheter was positioned at the level of the space between the sixth and seventh lumbar vertebra. After a stable plane of anesthesia was achieved, these dogs were each administered one of the following treatments epidurally : medetomidine $10{\mu}g/kg$ (Group M), a combination of medetomidine $5{\mu}g/kg$ and buprenorphine $10{\mu}g/kg$ (Group M/B), and a combination of medetomidine $5{\mu}g/kg$ and fentanyl $10{\mu}g/kg$ (Group M/F). Heart rate (HR), Respiratory rate (RR), End-tidal carbon dioxide (EtCO2), and arterial blood pressure were measured before drug administration (base line) and 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 min postinjection. Blood gas analysis was performed before injection and 5, 15, 25, 35, 45, 60 min postinjection. Isoflurane was discontinued 80 min postinjection and pain/motor function were evaluated up to 260 min postinjection every 15 min. At the early stage of drug introduction (until 5 min), the HR was decreased significantly in all 3 groups compared with base line. In Group M, HR was significantly decreased compared with the other 2 groups. With time (starting 20 min after drug introduction), the HR was decreased significantly in Group M/B in respect to base line. However, no significant difference was seen number-wise in all 3 groups. During 60 min after drug introduction, the systolic, diastolic and mean arterial pressures were highest in Group M and lowest in Group M/F. Among 3 groups, drug action and motor loss duration were longest in Group M/F. Analgesic effect observed in the M/F group was the most prominent and long-lasting, compared to those seen in the other 2 groups. Given the fact that the recovery of motor function takes place in a short period of time after analgesic effects disappeared, additional use of M/F depending on the patient's condition would be a good way to achieve effective pain management. However, proper care should be taken to ensure the function of cardiovascular system in the patient because the administration of M/F under isoflurane anesthesia results in a significant decline in arterial blood pressure ($65{\pm}10mmHg$).
