Cardiac transplantation has become an acceptable therapy for patients with end stage heart disease over the last decade. We experienced a case of heart transplantation to the 50 year old female patient. We used sterile technique all the time to reduce the incidence of infection. Anesthesia was induced and maintained with fentanyl 100 ㎍/kg. After cardiopulmonary bypass, blood products, inotropics and vasodilators were given to maintain myocardial contractility and cardiac output. The patient recovered uneventfully and discharged on 29th postoperative day.
In this article, the removal of surfactant by ozone and BAC was studied. Batch and pilot tests were carried out for these studies. In batch tests, efficiency of ozone oxidation process was evaluated for LAS(Linear Alkylbenzen Sulfonate) and SLS(Sodium Lauryl Sulfate) removal. Under oxidant conditions, the removal of LAS was more effective than of SLS. The removal of surfactant was more enhanced with increasing pH in oxidant systems. Pilot tests are carried out with BAC single process and ozone oxidation/BAC combined process. The removal of LAS was more effective in ozone oxidation/BAC combined process than BAC single process about 10∼20%. In the case of SLS, the efficiency of BAC single process was similar to that of ozone oxidation/BAC combined process. According to temperature, the removal efficiency of SLS changed from 70% to 95% and initial concentration of surfactant had no effects on removal efficiency of SLS under applied temperature above 15℃.
Induction of general anesthesia with tracheal intubation is routine procedure but causes significant tarchycardia and hypertension. Many approaches have been tried to attenuate these circulatory response. The effects of small dose fentanyl on arterial pressure and heart rate increase during intubation were studied in 40 normotensive patients, who were randomly allocated to two groups, receiving saline (Control group) or fentanyl 2μg/kg (Fentanyl group), in a double blind fashion during anesthetic induction with thiopental 5mg/kg. Systolic, diastolic, mean arterial pressure and heart rate were measured and rate pressure product was calculated. All parameters were significantly different between two groups (p$lt;0,05) and control group was significant increase in blood pressure and heart rate compared with pre-induction value but fentanyl group was relatively small changes of blood pressure and heart rate (p$lt;0.01). After tracheal intubation, incresed blood pressure was returned to pre-induction value within two t three minutes in fentanyl group but heart rate was not returned pre-induction value within 5 minutes. Dose of fentanyl that are low enough to cause any side effects of drug itself, no notable side effects were observed during study and recovery.
