Although halothane is generally anesthetic of choice for asthmatics due to its bronchodilatory action, its combined use with aminophylline should be discouraged. This report is a 43-year-old male who had primary closure and open reduction internal fixation (ORIF) for facial avulsion injury and zygomatic tripod fracture under N2O-O2-halothane anesthesia. About 90 minutes after the procedure, the patient who had aminophylline infusion for an acute bronchospasm developed a sudden cardiac arrest. The immediate cardiopulmonary resuscitation was applied and the patient was recovered without any neurological deficit. At the time, the serum theophylline concentration of the patient was 16 microgram/ml which was in the range of normal therapeutic dose. The cause for this cardiac arrest by halothane is unknown, but possibly a drug interaction between halothane and aminophylline might have contributed, since halothane sensitizes the heart to exogenous catecholamines.

BACKGROUND: The influence of preoperative starvation on blood glucose concentrations in children remains controversal. This period varies from 6 to 12 hr or even more, in different institutions. A surgical operation causes a rise in the blood glucose concentration, and this increased concentration returns to normal within 8 to 12 hr. The purpose of the present study was to investigate blood glucose concentra tions in children undergoing elective surgery who fasted before anesthesia. METHODS: One hundred sixty-five healthy children, aged less than 7 yr, and scheduled for elective minor surgery were included in the study. Blood samples were collected before induction of anesthesia, after induction of anesthesia and at the recovery room. The correlation between the period of starvation and the blood glucose concentration was estimated and hypoglycaemia was defined as a blood glucose concentration less than 40 mg%. RESULTS: The duration of starvation ranged from 10 to 14 hr in the majority of the patients (66.7%). The duration of starvation beyond 14 hr was 7.8%. No significant correlations were obtained between preoperative blood glucose concentrations and duration of starvation. None of the patients were hypoglycaemia before surgery. The intraoperative and postoperative blood glucose concentrations were significantly higher than the preoperative blood glucose concentration. CONCLUSIONS: In children less than 7 yr, blood glucose concentrations were not influenced by duration of starvation within a 14 time period.

Doxorubicin has characteristic chemomyectomy effect of the eyelid without disturbing other eyelid structures, but the major side effect of doxorubicin is the potential for eyelid skin injury as a result of the drug's toxicity in both animal and clinical studies. Verapamil may be used to reduce the dose of doxorubicin and the number of injections that would amplify the toxic effects of doxorubicin. This study was performed to determine whether there is an increase in the toxic effect of the doxorubicin as a result of verapamil pretreatment of the muscle. After 0.5mg, 1.0mg, and 2.0mg doxorubicin was injected in lower eyelids of each group, and equal dose of doxorubicin was injected fo11owing 1.0mg of verapamil injection in lower eyelid of each group, muscle cell loss were measured by light microscopy and side effect was observed. In verapamil and doxorubicin injection group, there was significant differences in the amount of preseptal muscle and even in the pretarsal muscle than the doxorubicin injection group in all doxorubicin doses. Verapamil, injected with a range of doses of doxorubicin, caused suhstantia11y increased muscle loss in the eyelid, compared with injection of doxorubicin alone. Skin ulceration, entropion or ectropion were not visible. Clinically, verapamil cotreatment might be useful to decrease the dose of doxorubicin injected and/or the total number of injections.

BACKGROUND: Impulse Oscillometry is a noninvasive and effort-independent test used to characterize the mechanical impedance of the respiratory system. The clinical potential of the 105 is rapid and demands only passive cooperation which makes it especially appealing for children, for epidemiologic surveys and for conditions in which quiet breathig instead of forced expiratory maneuvers are preferred. However, several studies have shown conflicting results that the role of 108 about detection of smoking induced small airway diseases or early airway obstruction METHODS: Study was to evaluate the clinical ability of the 108 to detect about smoking induced early airway obstruction in persons with normal spirometry test. Respiratory asymptomatic study groups were formed that one is non-smoking group, another is smoking group. RESULTS: The parameters of spirometry were not significantly differences between non-smoking group and smoking group. Among the parameters of 108, total resistance(non-smoking group: smoking group= 2.22 +/-1.20 : 2.58 +/-1.71), peripheral resistance( 1.25 +/-0.62 : 1.47 +/-0.10), bronchial compliance(0.44 +/-0.12: 0.47 +/-0.16) were not statistically significant different (p<0.05), but central resistance and lung compliance were not statistically significant different (unit ; resistance= hPa/l/s, compliance= 1/hPa). Resistance(Rrs) was not statistically significant different with changes of frequences(5, 10, 15, 20, 25, 30, 35Hz), but Reactance(Xrs) was statistically significant differenct with low frequences that X5(non-smoking group : smoking group= -0.62 +/-0.28 : - 0.76 +/-0.48, p<0.001) and X10(-0.06 +/-0.19 : -0.15 +/-0.33, p<0.013) (unit; hPa/l/s, hPa=cmH2O) CONCLUSION: Impulse oscillometer(IOS) is clinically available method to detect about smoking induced early airway obstruction. And clinically potential parameters of IOS were considers that total resistance, peripheral resistance, bronchial resistance, and reactance of low frequency at 5Hz, 10Hz.
