[Tubal pregnancy: recent aspects of diagnosis and treatment].
The histories of 139 patients who received treatment for tubal pregnancy between January 1975 and December 1981 in our department were reviewed. 12% of the patients had a prior contralateral tubal pregnancy. The commonest clinical finding was metrorrhagia in 84% of the cases. The HCG in the urine was positive in 68% of the cases with the clinical routine methods used up to date. The beta HCG in the blood showed an atypical trophoblastic process in all cases. The tubal pregnancy was diagnosed by ultrasonography in 19% of the cases and suspected in 54% of the cases. Aspiration of the pouch of Douglas verified the diagnosis in 79% of the cases. Laparoscopy confirmed the diagnosis in every case. Laparoscopy was especially required when the symptoms were unclear or when the aspiration of the pouch of Douglas showed negative or dubious results. 85 patients had a salpingectomy, 50 patients had a conservative operation of the tube. Laparoscopy was done in 34 patients who had a conservative tubal operation. In 79% of the patients an intact tubal wall made a conservative operation possible. 51 women desired further child-bearing by written questionnaire. After salpingectomy and normal contralateral fallopian tube at operation, 25 patients showed further desire for child-bearing. 18 cases delivered infants, three cases had abortions, and one case had a recurrent ectopic pregnancy. Following conservative operations 24 patients desired further children. 11 patients had intrauterine pregnancies, one of them an abortion. Five patients had a recurrent ectopic pregnancy.

The maximal rate of pressure rise in the right ventricle of isolated canine hearts in isovolumic and auxotonic systole under various hemodynamic and inotropic conditions.
The influence of changes in pre- and afterload, heart frequency and inotropic state on the difference between right ventricular dP/dtmax measured isovolumically and auxotonically has been investigated in canine heart-lung preparations. Isovolumic systoles were obtained by occluding the pulmonary artery during diastole by balloon inflation. The mean difference between isovolumic and auxotonic dP/dtmax is 40 mm Hg/sec (15 to 80 mm Hg/sec) - i.e. about 10% of the value measured auxotonically. Neither hemodynamic (pre- and afterload changes) nor inotropic changes influence this difference. Heart rate increase from 140 to 200/min also has no effect. This corresponds with the unchanged time interval between pulmonary valve opening and right ventricular dP/dtmax under all these conditions. Only heart rates below 100/min seem to enhance the difference between isovolumic and auxotonic dP/dtmax. Since the difference is not altered at various inotropic states, the result of this study leads to the conclusion that the relative changes in contractility could be slightly overestimated by using the auxotonic dP/dtmax for inotropic assessment. Practically, this inexactitude is within the error range of the method. Therefore, the use of dP/dtmax measured auxotonically does not introduce a marked disadvantage related to isovolumic dP/dtmax for assessment of relative inotropic changes of the right ventricle in isolated hearts.
