RESUMEN
Objective To assess the effect of dilute pituitrin solution (0.05 U/ml) on blood loss and distention fluid intravasation during hysteroscopy. Methods From January 2003 to June 2004, 68 women with abnormal uterine hemorrhage undergoing hysteroscopic endometrial resection were randomly divided into treatment and control groups (34 cases in each). In the treatment group, dilute pituitrin solution (0.05 U/ml) was injected into the cervix before dilation of the cervix in preparation for hysteroscopy, while the patients in the control received no pituitrin injection. Results The mean operation time in the treatment group was significantly shorter than that in the control [(32.2?6.0) min vs (35.9?6.8) min; t=-2.379, P=0.020]. The amount of distention fluid infusion in the treatment group was significantly less than that of the control [(2982.1?880.5) ml vs (3461.2?795.8) ml; t=-2.354, P=0.022]. The volume of distention fluid intravasation in the treatment group was significantly less than that of the control [(225.3?81.1) ml vs (319.4?89.2) ml; t=-4.551, P=0.000]. The rate of fluid intravasation was (7.5?1.1)% in the treatment group that was significantly lower than that in the control [(9.2?1.1)%, t=-6.372, P=0.000]. The mean blood loss in the treatment group was significantly less than that of the control [(15.1?4.1) ml vs (24.7?6.6) ml; t=-7.204, P=0.000]. Conclusions Intraoperative administration of dilute pituitrin solution can reduce blood loss, operation time, and the amount of distention fluid infusion and intravasation. As a result, it is useful to avoid post-hysteroscopy complications including TURP syndrome.

Objective To investigate the effects of human immunodeficiency virus (HIV) infection on the pregnancy outcome and the incidence of vertical transmission in HIV positive pregnant women Method 86 cases of HIV positive pregnant women and their infants were evaluated retrospectively, and HIV antibody in peripherial blood was detected using enzyme linked immunosorbent assay (ELISA) Results Compared with normal control group, the incidences of abortion, preterm birth, low birth weight and small for gestational age babies were 9 3%, 14 0%, 16 3% and 10 5%, respectively ( P
