Clinical study on the Occurence of Cardiac Arrhythmia on the Electrocardiogram during Anesthesia in the Old Patients / 대한마취과학회지

After analyzing the electrocardiographic findings during anesthesia, we estimated the difference in the incidence of the operative arrhythmia according to preoperative electrocardiographic findings and compared the influence on the occurrence of the operative arrhythmia according to the type of anesthesia(general and spinal) and major inhalational anesthetics. The results were as follows: 1) On the preanesthetic electrocardiographic findings, the number of patients with only normal rhythm was 15 cases. 2) During anesthesia arrhythmias appeared in 15 patients(305) and the most frquent arrhythymis was premsture ventricular contraction. 3) Between the patients with normal presnesthetic electrocardiographic findings and abnormal electrocardiographic finedings, the incidences of operative arrythmias were not significantly different. 4) Thirty percent of patients developed the arrhythmia both in general and spinal anesthesia. 5) The incidence of arrhythmia in halothane and enflurane aneshtesia was respectively 32% and 28% but the difference was not significant.

The Clinical Study for Upper Respiratory Infection in Surgical Intensive Care Unit Patients with Tracheostomies / 대한마취과학회지

Infections that occur within the surgical intensive care unit represent a significant cause of patient morbidity and mortality. In addition, hospital-related infections prolong hospital stay and increase hospital-charges. Moreover for the patient with tracheostomy, the possibility of cross-infection may impose an added risk when the general condition is poor. This study was undertaken to investigate the incidence of upper respiratory infection in patients with tracheostomies who had respiratory care in the surgical intensive care unit. The total number of cases in this study was 20, and the specimens for bacteriologic culture were taken especially from the regions of the upper respiratory tract via tracheostomy tubes on the 1,3,5,7 and 10th day after tracheostomy. The results obtained from the bacteriologic culture were as follows: 1_ The most frequently found organism was Pscudomonas aeruginosa, and newxt was staphylococcus, followed by beta-hemolytic streptococcus and Escherichia coli. Gram negative bacilli were 58.9% of all cultured organisms. 2) The greatest number of organism was seen on the third day and frequency of mixed growth was increased in process of time. 3) The comparative sensitivity test of Pseudomonas seruginosa showed that all strains were resistant to ampicillin, erythromyclin, penicillin and tetracycline and 70% of strains were sensitive to amikacin.
