BACKGROUND: The usage of appropriate disinfectants is essential for infection control in a hospital. Inadequate use of disinfectants is the cause of human or environmental toxicity and is a waste of cost. The objective of this study was to describe the status of the usage of disinfectants in Korean hospitals. METHOD: One hundred and eighty three hospitals of over 300 beds were investigated by a questionnaire distributed by mall. Data collection was done on November 1999. The questionnaire was made by the Association of Infection Control Nurses in Korea, based on references and protocols of the Korean Society of Nosocomial Infection Control. Numerical and percentage data were analyzed by SPSS. RESULTS: The collection rate of the questionnaire was 43.7% (80/300). Thirty five hospitals (46.7%) had an official process in selecting disinfectants in their hospitals. Regarding skin antiseptics, 10% povidone iodine and 70% alcohol were commonly used in skin preparation for intravenous catheterization or pre-operative skin disinfection, For disinfection of mucosal membranes such as mouth and periurethral area, 3% boric acid solution or 3% H202 were used. Most of the hospitals decontaminated contaminated medical instruments manually with dodecyl diamino ethyl glycine (20.8%). glutaraldehyde (15.6%). quaternary ammonium compounds (13.8%), virkon (12.3%) and sodium hypochlorites (11.7%). Glutaraldehyde and virkon were frequently used for disinfection of endoscopes. Sodium hypochlorites (48.9%) and quaternary ammonium compounds (19.8%) were the most commonly used environmental disinfectants. Some noticeable problems in disinfectants were as follows. First, for mouth care, many hospitals (41.7%) over-used boric acid, which has cumulative toxicity for humans. Second, many hospitals had an incorrect protocol of disinfecting endoscopes. Third, for environmental decontamination and instrument cleaning, some hospitals used high level disinfectants such as glutaraldehyde, which is too costly and provides unnecessary safety problems. Fourth, after patient discharge, many hospitals did not use disinfectants at all. Considering the specific Korean medical environment of high incidence of multi-drug resistant microorganisms, use of disinfectants for discharged environments may be warranted. CONCLUSION: This study included only hospitals of over 300 beds, which has a limitation in representing the status of disinfectants usage in a country. However, significant problems from misunderstanding the basic principles of disinfectants and misusages of disinfectants were observed in this investigation. These observations will provide useful information for designing a guideline for the appropriate uses and for efficient education of disinfectants, and also for planning a national control program for proper disinfectants usage in this country.

BACKGROUND: Vecuronium and Pancuronium have been proven to be associated with nicotinic receptor of skeletal muscle. Generally, nondepolarizing muscle relaxant is associated with contraction of smooth tracheal muscle, but there have been few studies about effects of nondepolarizing muscle relaxant on the smooth tracheal muscle. METHODS: We studied the acetylcholine dose response curve of the tracheal smooth muscle contraction and effects of propranolol, L-NAME after pretreating with vecuronium and pancuronium. RESULTS: Vecuronium shifted the acetylcholine dose-response curve of the tracheal contraction to the left, and pancuronium shifted the curve to the right. Vecuronium and Pancuronium reduced the contraction of smooth tracheal muscle with the use carbachol. Propranolol and L-NAME had no effect on the contraction of smooth tracheal muscle after pretreating with vecuronium and pancuronium. CONCLUSION: We suggest that vecuronium has an anticholinergic effect, while pancuronium has some effect on the muscarinic receptor in addition to its anticholinergic effect.

The dose-response for glycopyrrolate and heart rate in anesthetized children has not heen defined. We determined the dose-response for glyeopyrrolate and heart rate in 50 children, ASA physical status l and 2, anesthetized with halothane and nitrous oxide. Anesthesia was induced with 60-70% nitrous oxide in oxygen and halothane(1.5-2.0 vo1%). After induction of aneethesia, glycopyrrolate in a dose of 4, 6, 8, 12 or 16ug Xkg(-1) was administered by rapid infusion to each subject. The effects of glycopyrrolate on heart rate, heart rhythm and systolic blood pressure were compared among dosage groups, and dose-response curve for peak heart rate was constructed, Glycopyrrolate increased the heart rate in a dose-related manner upto 12 ug X kg(-1) except 16 ugX kg(-1). Fifty percent maximal response corresponded to 6.1 ug X kg(-1), and 95% maximal response corresponded to 11.1 ug X kg(-1) . None of the patients had nonsinus rhythm after glycopyrrolate injection. Except for glycopyrrolate given at 4 ug x kg(-1), the systolic blood pressure increased significantly after all other doses. Glycopyrrolate in doses greater than or equal to 6 ug X kg(-1) increased the heart rate and systolic blood pressure in children anesthetized with halothane and nitrous oxide.

Atlanto-axial instability is an important condition that may threaten the integrity of spinal cord, leading to tetraplegia or sudden death. Many of these require operative stability, and several different operations have been advocated. Among these methods, Brooks and Jenkins posterior fusion for eleven cases of atlanto-axial instability (fresh fracture of odontoid process in nine, nonunion of odentoid fracture in one, Cl-2 rotary subluxation in one) was performed in Baik Hospital from July 1978 to June 1987, and the following results were obtained. l. Accurate reduction and immediate rigid stability were obtained with Brooks and Jenkins posterior fusion, so early ambulation with simple external support was begun within 2 weeks after operation. 2. Radiological fusion of atlanto-axial instability were seen in average 12 weeks after operation. Therefore posterior atlanto-axial fusion by Brooks and Jenkins method is an excellent method for operative treatment of atlanto-axial instability.

BACKGROUND: This study was conducted to investigate risk factors for perioperative periods between general anesthesia (GA group) and thoracic epidural blockade combined with general anesthesia (CEA group) for consecutive hepatic resections. METHODS: A retrospective chart review was carried out regarding 85 patients who had undergone hepatic resections. We compared the effects of postoperative pain control in the two groups, including pulmonary complications and durations of hospital stay. RESULTS: There was no significant difference in demographic data between the two groups. The perioperative fluid requirement and transfusions were lower in the CEA group. Supplemental analgesics requirement was significantly lower in the CEA group than the GA group in the 3 days postoperatively. There were no statistical difference between the two groups in nausea, vomiting, urticaria, constipation or urinary retention, but hypotension was more pronounced in the CEA group than the GA group. Postoperative pulmonary and surgical complications were similar between the two groups, but the duration of hospital stay was longer in the GA group than the CEA group. CONCLUSIONS: We conclude that the thoracic epidural blockade combined with general anesthesia provided lower surgical blood loss and better postoperative analgesia and hospital stay than general anesthesia for hepatic resections.

OBJECTIVES: Congenital muscular torticollis, a common disorder that refers to the shortening of the sternocleidomastoid in infants, is sensitive to correction through physical therapy when treated early. If physical therapy is unsuccessful, surgery is required. In this study, we developed a support vector regression model for congenital muscular torticollis to investigate the prognosis of the physical therapy treatent in infants. METHODS: Fifty-nine infants with congenital muscular torticollis received physical therapy until the degree of neck tilt was less than 5degrees. After treatment, the mass diameter was reevaluated. Based on the data, a support vector regression model was applied to predict the prognoses. RESULTS: 10-, 20-, and 50-fold cross-tabulation analyses for the proposed model were conducted based on support vector regression and conventional multi-regression method based on least squares. The proposed methodbased on support vector regression was robust and enabled the effective analysis of even a small amount of data containing outliers. CONCLUSIONS: The developed support vector regression model is an effective prognostic tool for infants with congenital muscular torticollis who receive physical therapy.
