A2 D time, a time interval from aortic second heart sound to the D point of mitral valve echogram, was reported as a valuable index of the left ventricular relaxation in its early diastole. It was suggested, however, that A2D time is influenced by variable factors rather than single factor. This study was performed to evaluate the influences of several on the A2D time and to extend our understandings in A2D time. For this purpose, A2D time was measured in 4 groups whose hemodynamic states were different, i.e.31 normal subjects (group A), 32 patients with essential hypertension without decompensation (group B), 10 normotensive patients with clinically full blown congestive heart failure (group C), and 11 patients with hypertensive heart failure (group D), and the mean values of each group were compared between the groups. Concordantly systolic hemodynamic parameters were observed and the relationship of A2D time and each of these parameters were observed. A2D time was consistently influenced by the level of left ventricle impedance and it is well correlated with parameters representing left ventricular systolic performances. In hypertensive subiects, A2D time was increased before the deterioration of the left ventricular systolic function but shortened after clinical heart failure. These findings suggest that A2D time may be of value in longitudinal follow-up of the left ventricular function in the hypertensive patients even before the development of clinical heart failure.

PURPOSE: The purpose of this study was to examine the effects of frozen gauze with normal saline on thirst and the oral health of patients with nasal surgery. METHODS: A quasi-experimental, nonequivalent control group pretest-post test design was used. Participants (n=52) received either gauze frozen with normal saline (n=26), or wet gauze (n=26). The subjective thirst level and oral health of the participants were assessed before the intervention, 30 minutes after the first intervention, 30 minutes after the second intervention, and 30 minutes after the third intervention. RESULTS: After oral hygiene was provided twice, the thirst level was improved in patients receiving the gauze frozen with normal saline. After oral hygiene was provided a third time, the thirst level was improved in patients receiving the gauze frozen with normal saline. CONCLUSION: Gauze frozen with normal saline can be effective for oral hygiene in reducing the thirst level and improving the oral health in nasal surgery patients.

The hypotensive effect of tripamide(Normonal(R)) were evaluated in 31 cases of essential hypertension. Fifteen to thirty mg of tripamide per day were administered continuously for 8 weeks. The results were as follows; 1) The systolic blood pressure was significantly lowered from 175+/-15 mmHg(Mean+/-SD) before treatment to 144+/-17 mmHg after treatment(p<0.01), and the diastolic blood pressure was significantly lowered from 106+/-11 mmHg before treatment to 90+/-12 mmHg after treatment(p<0.01). 2) The systolic blood pressure was lowered 20 mmHg or more in 25 out of 31 cases(80.7%), and the diastolic blood pressure was decreased 10 mmHg or more in 25 out of 31 cases(80.7%) at the end of 8 weeks treatement. 3) There was no significantl differences in the level of SGOT, serum cholesterol, serum electrolytes(Na+, K+, Cl-), BUN, creatinine and urinc acid before and after treatment with tripamide. 4) In most cases the subjective symptoms disappeared or became easier after tripamide treatment. 5) Profound weakness was developed in 2 cases during tripamide administration.

This study was made to evaluate the effect of oral atenolol, a cardioselective beta-adrenergic blocking agent without intrinsic sympathomimetic activity, on left ventricular function in patient with essential hypertension. Atenolol, 100mg/day, was given to 11 hypertensive patients for 4 weeks, and its effects on arterial pressure, pulse rate, left ventricular dimensions and ejection phase indices of myocardial performance were examined by echocardiography. Echocardiographic studies were performed before treatment and after 4 weeks of atenolol therapy. Arterial pressure fell form 145/90 mmHg to 138/84mmHg after 4 weeks. Pulse rate fell significantly from 69/min to 58/min(p<0.05). Left ventricular end-diastolic and end-systolic dimensions and mean rate of circumferential fiber shortening(mVcf) did not change significantly. Ejection fraction increased significantly from 0.66 to 0.72(p=0.01). This results indicate that atenolol in the resting state has no depressant effect on left ventricular function in patients with essential hypertension.

Fistula between the right renal artery and the infereior vena cava is a rare disorder, of which only 7 cases were reported in so far as the authors have reviewed. A 34-year-old man, who had got a stab wound on the abdomen and undergone an abdominal surgery 12 years ago during his military service, visited the hospital because of occipital headache and known hypertension for 5 years. On examination, his blood pressure was 200/140mmhg, and a thrill and loud continuous vascular bruits over the paraumbilical and right loin region were noted. his blood pressure was refractory to usual antihypertensive regimens. The chest X-ray film showed cardiac enlargement and pulmonary congestion. With the aids of abdominal ultrasonogram, static and dynamic renal scanning with (99m)T-DTPA, excretory urogram, aortogram and selective right renal angiogram, he was diagnosed as right renal artery inferior vena cava fistula. After fistulectomy and repair of walls of both vessels, his blood pressure was successfully controlled with drugs.

Dieulafoy's lesion is an uncommon cause of recurrent massive gastrointestinal bleeding resulting from an abnormally large submucosal artery that protrudes through a small mucosal defect. Incidence of Dieulafoy's lesion as a source of upper gastrointestinal bleeding ranges from 0.3 to 6.7% in adults. But recently, the incidence is on an increasing trend by advanced endoscopic diagnostic technique. Lesions may occur anywhere in the gastrointestinal tract but are typically located within 6 to 10 cm of the gastroesophageal junction, generally along the lesser curvature of the stomach. Lesions are life threatening because bleeding is often massive and recurrent. The mean age of presentation is in the fifth decade and patients of pediatric age are extremely rare. We report a 12-year-old male patient who had Dieulafoy's lesion, diagnosed by emergency gastrointestinal endoscopy. Endoscopic finding was active bleeding from Dieulafoy's lesion in the duodenal second portion. Bleeding was controlled with endoscopic hemoclipping without complication or recurrence.

Rupture of intracranial vessel during general anesthesia dramatically jeopardise patient's state and may lead to death. A sudden cardiovascular change during intubation and extubation in general anesthesia is dangerous, especially in patient with coronary and intracranial vascular disease. Myocardial infarction, congestive heart failure or intracranial hemorrhage can occur in such condition, but these occur rarely. We discovered the rupture of the hidden intracranial arteriovenous malformation in 13 years old female patient after tonsillectomy. We discuss about prognosis, prophylaxis and management of the intracranial arteriovenous malformation rupture during general anesthesia.
