OBJECTIVES: To review the drug prescription pattern of antiulcerative agents for elderly inpatients. METHODS: The study population comprised inpatients of community hospitals who were members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, beneficiaries of the Korea Medical Insurance Corporation (KMIC) and residing in Busan city in 1993. The drug prescription information was collected from the claims data of hospitals where the cohort members received medical care between January 1993 and December 1994. The information included personal identification, age, gender, diagnosis, drug dosage, date of hospital admission and name of medical institutions where the study subjects received drug prescriptions. The data analysis produced outcomes in terms of distribution of antiulcerative agents by class and by medical institution and trend of relative prescription. Analysis was also performed in terms of combined prescriptions of antiulceratives and drugs that could induce risk from drug interaction with antiulceratives. RESULTS: The number of patients prescribed antiulcerative agents was 1,059 (64.9%) male and 1,724 (65.5%) female among the total inpatients. An antacid and composite agent was the most frequently prescribed antiulcerative agent (70.8%), followed by H2 antagonist (16.0%). Among the potential drugs that could induce risk from drug interaction with the antiulcerative agents, diazepam was the most frequently prescribed. The proportion of diazepam co-prescription was 22.5% of the total cimetidine prescriptions and 14.5% of the total omeprazole prescriptions. CONCLUSIONS: Antiulcerative drugs were frequently prescribed in the elderly inpatients. The adverse drug reaction could possibly be due to drug interaction. The study results could be used as fundamental data for further drug utilization review of antiulcerative agents.

BACKGROUND: All medical conduct should be practiced under the permission of patients or guardians. Because anesthetic procedures have high risk, every anesthesia practice is done under verbal and/or written consent. However, collecting anesthetic permission is not common in Korean medical anesthesiologists. The purpose of this article is to survey current anesthetic status and to provide some suggestions. METHODS: We had given questionnaire sheet to anesthesiologists participating in an annual meeting of the Korean Society of anesthesiologists. It included the percentage of receiving the anesthetic consent, the reasons why they received the informed consent or not, and the conditions to improve to receive it. RESULTS: The total number of responded anesthesiologists was 187. More than half of the responders had received the informed consents from less than 25% of their patients. And only thirty percent of them had taken the consents from more than 75% of their patients. To increase this rate, they replied, it is needed to strengthen the legal validity of the consent and to improve working conditions. CONCLUSIONS: The rate of receiving the informed consent is very low for the anesthesia practice in Korea. There are some procedures that are needed to improve the current situation so that anesthesiologists can provide better quality to the patients.

Takayasu's arteritis (TA) is a chronic inflammatory disease involving the aorta. Because TA sometimes involves cerebral arteries, anesthetic debates focus on cerebral monitoring. There is limited evidence as to which cerebral monitoring method is most adequate. Furthermore, there is insufficient evidence to determine which anesthetic technique is better for TA parturients. We experienced the case of a TA parturient who developed transient cerebral ischemia during cesarean section. The patient's TA involved her cerebral arteries, and her regional cerebral oxygen saturation (rSO2) was lower in the left side than in the right side. She complained of speech impairment, tinnitus, and stiffness of the posterior neck when the rSO2 levels dropped. The FloTrac/Vigileo(TM) system did not correlate with clinical symptoms, but the cerebral oximeter displayed the low oxygen saturation. We recommend the cerebral oximetry for cerebral monitoring in TA parturients who undergo cesarean sections, especially in hemodynamically unstable patients under regional anesthesia or unconscious patients under general anesthesia.

Opioids are widely used as painkillers and anesthetics. Though we use opioids to relieve pain, these drugs can induce mood elevation, dependency, and withdrawal symptoms. This is why opioids are controlled-substances. Most physicians think that some substances should be controlled if they have opioid-like pharmacological properties, especially a long duration, preservation of respiration, and dependency. It is noteworthy that short-acting substances, such as midazolam and thiopental, are included in controlled substances. Their abuse is very dangerous because they frequently induce severe respiratory depression due to a narrow therapeutic window. Teaching point of this article is that designation of a new drug as a controlled substance requires scientific evidence of its link to dependency and/or withdrawal symptoms. However, this does not require abusers' convenience (long duration) or safety (maintenance of respiration). The authors present the addiction and abuse patterns of propofol as an reasons for the Korean Food and Drug Administration to designate propofol as a controlled substance. As a future study, an animal and/or a clinical model for dependency is needed to identify addictive substances. Though several neurotransmitters and their loci in the central nervous system have been studied, the precise mechanism for addiction is unknown. Also, it should be recognized that the potential for drug addiction and abuse could be masked in the early marketing period of a new drug. Physicians should monitor patients' responses carefully when they deal with the drug.

BACKGROUND: Surgical patients should be provided adequate information on operation. The information on mortality is extremely important among them. The purposes of this study are to investigate the recent mortality associated with anesthesia and surgery, and to get a logistic regression model of mortality based on patient information. METHODS: We collected all of the anesthetic cases except local anesthesia during 5 years (between 2000 and 2004) in a hospital. All deaths within 7 days after anesthesia were retrieved. These data were analyzed in terms of age, gender, department in charge, time point after anesthesia, elective or emergency surgery, type of anesthesia, operation name, and diagnosis. The combined effects of the variables on the mortality were evaluated with logistic regression. The causes of death were also analyzed. RESULTS: There were 155 deaths among 74,458 patients under anesthesia. Age less than 1 year old or greater than 80 years old, male gender, department of thoracic surgery, emergency operation, cardiovascular surgery, and diseases for transplantation had higher mortality than their counterparts. Regression model was followed with assignment of '1' for the above mentioned categories. Other categories were designated by '0'. Log[p (death)/{1-p (death)}] = -9.15+1.03xage+0.66xsex+0.79xdepartment+2.77xemergency+2.52 xdiagnosis+0.89xoperation The leading cause of death was sepsis (21.9%). CONCLUSIONS: The average of mortality within 7 days after anesthesia was 21 per 10,000 anesthetic cases (0.21%). Estimated mortality based on logistic regression ranged from 0.01% to 10.25% depending on patient information.

BACKGROUND: There is a legal obligation to explain the procedure and use of epidural analgesia in labor primarily due to the possibility of potential risks and associated complications. The present study details on the survey carried out to ascertain the current status of obtaining informed consent (IC) for explaining the epidural analgesia in labor. METHODS: The present study is based on a survey through a telephone questionnaire that covered all the hospitals in Korea where the anesthesiologists' belonged to and are registered with Korean Society of Anesthesiologists. The questionnaire included questions pertaining to administration of epidural analgesia to a parturient, information on different steps of obtaining an IC, whether patient status was evaluated, when the consent was obtained, and the reasons behind, if the consent had not being given. RESULTS: A total of 1,434 respondents took part in the survey, with a response rate of 97% (1,434/1,467). One hundred seventy-four hospitals had conducted epidural analgesia on the parturient. The overall rate of obtaining IC for epidural analgesia during labor was 85%, of which only 13% was conducted by anesthesiologists. The rate of evaluating preoperative patient status was 74%, of which 45% was conducted by anesthesiologists. Almost all of the consent was obtained prior to the procedure. CONCLUSIONS: The rate of obtaining IC for epidural analgesia in labor is relatively high (85%) in Korea. However, it is necessary to discuss the content of the consent and the procedure followed for obtaining IC during the rapid progress of labor.
