El método más utilizado fue la punción del saco de Douglas (36,7 %). Las principales complicaciones fueron la anemia (62,1 %) y el shock hipovolémico (25,3 %). A retrospective study of 256 patients that had an operative diagnosis of ectopic pregnancy at the Gynecology Service of the "Carlos Manuel de Céspdes" Hospital of Bayamo, in the province of Granma, from January 1, 1994, to December 31, 1996, was conducted aimed at knowing the relationship of some epidemiological, clinical, diagnostic and therapeutic factors in this entity.

Descriptive statistical techniques as that of percent were used. Techniques of statistical significance such as the chi square test and the difference between proportions were also applied, taking p < 0.01 as significant values. 37.9 % of the patients were between 19 and 24 years old. In this age group 15.4 % had suffered from pelvic inflammation with marked differences in comparison with other age groups (p < 0.01). The predisposing factors appearing in the first places were: pelvic inflammation, infertility and curettages with 37.9; 26.6 and 19.5 %, respectively. The puncture of Douglas’pouch was the most used method (36.7 %). The main complications were anemia (62.1 %) and the hypovolaemic shock (25.3 %).

Abstract: five hexahydroquinolines were prepared through one-step synthesis from an aromatic aldehyde called ?- alkyl aminocrotonate (enamin)and dimedone in pure ethanol as solvent. the effects of the five hexahydroquinolines on contractility of rabitt′s aorta rings and on contractility of papillar muscles of rat′s right ventricle were characterized in a comparative way to classical nifedipine. all hexahydroquinolines inhibited the contractile activity of both vascular smooth muscle and cardiac muscle, and they showed effects that are characteristic of calcium antagonist compounds, although with less potent action than nifedipine. however, two of the studied hexahydroquinolines presented some mild vasoselectivity.
