N/A Clinical observations were made on 24 cases of acute drug itoxication who were admitted to the Department of Internal Medicine, Pusan Adventist Hospital from January 1984 to December 1987 and the following results were obtained. 1) The total number of cases of acute drug intoxication was 274 which was 0.94% of the total patients of the emergency room. 2) The ratio of male to female was 1:1.8 The age incidence was highest in the 3rd decade age group (38.7%). 3) The incidence was highest in May and during the spring season. 4) The motive for intoxication was suicidal attempt in 87.3% and accidental poisoning in 21.8% of cases. 5) The most common drug of intoxication was sedatives (26.6%) and the others were rodenticides, pesticides, and miscellaneous unknown drugs in order. 6) Most cases complained of impairment of conscious- ness. Vomiting, abdominal pain and convulsion were frequently observed. Physical examination revealed increased pules, increased blood pressure, sweating, increased bronchial secretion and miosis of the pupil, Such symptoms and physical signs were more prominent in pesticide intoxication. 7) Leukocytosis was common in pesticide intoxication (54.0%). 8) The overall mortality rate of total cases was 4.7% and the mortality rate was highest in pesticide intoxication.

N/A In order to assess the possibility of noninvasive estimation of pulmonary artery pressure by Doppler echocardiography, pulmonary artery pressures estimated by continuous wave Doppler echocardiography were compared with those measured by cardiac cath-eterization in 10 patients with tricuspid and pulmonary regurgitation. Doppler-determined pressure gradients were estimated from the tricuspid and pulmonary regurgitant flow velocity(V) by means of the simplified Bernoulli equation(ΔP =4v²). The results were as follows: Pressure gradients (PGs) between right ventricle and right atrium at systole measured by Doppler method and catheterization were 58.05±11.67, 59.12±13.78 mmHg, respectively, and correlated well with each other (r=0.95, p<0.01). As for pulmonary arterial systolic pressure (PASP), PGs added by assumed (5 mmHg) right atrial pressure (RAP) and by actual RAP, and catheter-measured PASP were 63.05±11.67, 63.93±11.59, 66.30±12.26mmHg, respectively, and PGs added by assumed RAP and by actual RAP correlated well with catheter-measured PASP, respectively (r=0.97, p<0.01; r=0.98, p<0.01). The PGs between pulmonary artery and right ventricle at end-diastole measured by Doppler method and catheterization were 20.48±4.35, 20.90±4.87, respectively, and correlated well with each other (r=0.97, p<0.01). As for pulmonary arterial diastolic pressure (PADP), the PGs added by assumed (5 mmHg) right ventricular end-diastolic pressure (RVEDP) and by actual RVEDP, and catheter-measured PADP were 25. 48±4.35, 26.38±4.04, 26.80±4.40mmHg, respectively, and PGs added by assumed RVEDP and by actual RVEDP correlated well with catheter-measured PADP, respectively (r=0.96, p<0.01; r=0.96, p<0.01). Doppler-determined PG between the pulmonary artery and right ventricle at early diastole and catheter-measured mean pulmonary arterial pressure were 37.30±6.31, 40.30±5.53mmHg, and correlated well with each other (r=0.81, p<0.01). In conclusion, pulmonary arterial systolic, diastolic pressure and mean pulmonary arterial pressure could be well predicted noninvasively by continuous wave Doppler echocardiography in patients with tricuspid and pulmonary regurgitation,
