의료기술의 발달로 오늘날의 개심술은 대부분 성공적으로 시행되고 있지만 극히 일부분은 아직도 개심술후 심한 심실기능의 저하로 사망하는 겨우가 있다. 1960년대 중반 Spencer와 DeBakey에 의해 개심술후 심한 심실기능이 저하된 환자에게 심실보조장치를 이용하여 성공적으로 치험한 이후로 많은 발전을 거듭해 왔다. 저자들은 4개월 (6.5Kg)된 남아에서 개심술후 심한 저심박출증으로 인공심폐기의 제거를 못하여 좌심실 보조장치(Centrifugal Biopump)를 사용하여 성공적으로 치험하였기에 보고하는 바이다.

임심 중 심폐바이패스를 사용하는 개심수술은 산모뿐 아니라 태아계에도 영향을 끼치기 때문에 중요하다. 임신 중 항응고제 투여을 부적절하게 하여 기계판막 기능부전이 초래된 임신 31주의 산모에서 심장 재수술에 앞서 제왈절개로 태아 출산 후 20시간 뒤 산모의 개시수술을 성공적으로 시행하였기에 보고하는 바이다.

Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.

This survey was performed from March 1993 to March 1998, in order to clarify the relationships between water quality and topographical factor. The study sites were two reservoir basins; Kaesim and Jangchan in Iwon-myon, Okchon-gun, Chungcho'ngbukdo Province. Basin shape factors of Kaesim reservoir were at 0.030∼0.210 (mean value 0.090), those of Jangchan reservoir were at 0.217∼0.452 (mean value 0.325). The mean basin shape factor of Jangchan reservoir was 3.61 times larger than that of Kaesim reservoir because its stream width was narrower and mean stream length was shorter. In the correlation between distance from the source of stream (L) and basin area (A), Iwonchon basin was calculated as L=1.44A/sup 0.6/. Circularity ratio was 17.114 in Kaesim (22% of Kum River), and 7.444 in Jangchan. Elongation ratio was 0.357 in Kaesim, 0.636 in Jangchan and 0.282 in Kum River. Precipitation summation period of Jangchan was 1.54 times slower than that of Kaesim. Rainfall reaching time in each small basin was 337.53 min. in A'(Jangchan-ri) basin of Jangchan and 49.26 min in H (Iwon-ri) basin of Kaesim. In the relationship between watershed frequency (Df) and drainage density (Dd), the regression equation was Df=0.023Dd² in Kaesim and Df=0.189Dd² in Jangchan reservoir. As slope degree increased, DO became higher (Y/sub DO/=0.19X＋6.5927, r=0.8l), but COD(Y/sub COD/=-0.2092X＋9.7104, r=0.52) became lower. Total nitrogen was increased with the increase of basin shape factor and circularity ratio. Ratio of B/sub OD/ to COD was 1/1.2(Y/sub BOD/ = 1.2984 X/sub COD/-3.2004, r=0.9l).

The vasodilatory shock after cardiopulmonary bypass is defined as the condition involving severe and persistent form of hypotension, tachycardia, normal or increased cardiac output and decreased systemic vascular resistance. Because of the unsuccessful response to infusion of fluids or catecholamine vasopressors, a sustained systemic shock state occurs and results in a high morbidity and mortality. We successfully treated this syndrome of 3 patients after open heart surgery with low dose of arginine vasopressin(AVP). Therefore, we report these cases with a review of related articles.
