OBJECTIVE: To assess misoprostol's ability to prevent postpartum hemorrhage (PPH) where no alternatives exist. Comparison to oxytocics demonstrates how similarly misoprostol achieves a level of effectiveness-obtainable only in hospitals-in remote locations around the world. METHOD: Using the Mantel-Haenszel fixed-effects model and the DerSirmonian and Laird random-effects model, summary statistics indicated that misoprostol's excess risk of PPH was only 4% when compared to oxytocics. RESULT: This risk difference was well within the range of expected results for all uterotonic agents and does not warrant branding misoprostol as an inferior drug. CONCLUSION: Conventional uterotonic drugs should not be used to set the lowest-accepted level of effectiveness in settings where they are entirely unsuitable. Continuing to weigh the benefits of one effective drug against another only delays the distribution of misoprostol in countries where it is the only feasible choice and must be measured against no treatment at all. 相似文献

脑梗死后再发缺血性卒中与脑出血患者微血管病变及预后的比较 总被引:1,自引:0,他引:1
【目的】探讨脑梗死后再发缺血性卒中与脑出血患者的临床特点、影像学上微血管病变及预后的异同。【方法】连续收集急性复发性卒中的住院病例(初发事件为脑梗死,复发事件包括脑梗死或脑出血),详细记录临床资料。观察脑内微出血及自质病变的严重程度,随访有无严重血管事件及死亡的发生。【结果】175例再发脑梗死患者。19例复发事件为脑出血的患者进入本研究。155例(88.6%)再发脑梗死患者,以及18例(94.7%)脑出血患者存在自质病变。77例(44%)再发脑梗死患者和16例(84.2%)脑出血患者存在脑内微出血。脑出血组自质病变的严重程度及微出血的数目均明显高于再发脑梗死组(P=0.033,0.016),脑出血组的死亡率及再发脑出血的危险性明显增高(P=0.034,0.036)。【结论】严重的脑自质病变及微出血的出现与脑梗死后再发脑出血有关。多发微出血提示出血风险增高。如复发事件为脑出血,则其死亡率及再次复发脑出血的风险均明显增加。 相似文献

In a pilot study of 6 patients with subarachnoid hemorrhage caused by a ruptured intracranial (grade IV (Hunt and Hess) aneurysm the hemodynamics and plasma-nimodipine concentrations have been observed during a 3-week period of treatment. We found that 3 patients developed reversible hypotension during the nimodipine treatment and that the hypotension tendency could be related to the plasmanimodipine level and not to a more or less severe sensitivity to nimodipine.
Repeated measurements of blood pressure, plasma-nimodipine and regional cerebral blood flow (rCBF) are necessary for the purpose of obtaining the optimum treatment and for evaluating the effect of treatment. 相似文献

K. SIEUNARINE P. MOXEY D.C.M. BOYLE L. UNGAR† I. LINDSAY‡ G. DEL PRIORE§ & J.R. SMITH§ 《International journal of gynecological cancer》2005,15(5):967-973
While developing the technique of abdominal radical trachelectomy for conservative cervical cancer management, the vascular supply of the uterus was thoroughly examined. The question of how many vessels the uterus requires to ensure its viability arose. Following an abdominal radical trachelectomy for stage IB cervical carcinoma, blood supply of the body of the uterus is successfully maintained by only the two infundibulopelvic vessels (n= 34). Pregnancy has resulted following this technique (n= 2). Selective ligation of the pelvic vasculature has been utilized in the abdominal radical trachelectomy procedure. The objectives of this study were to investigate the vasculature of the infundibulopelvic and broad ligaments, to assess the contribution of the ovarian and uterine vessels to overall uterine perfusion, and to consider the clinical applications of selective pelvic vessel ligation. Ten fresh dissections of the infundibulopelvic vessels, broad ligaments of benign total abdominal hysterectomy, and bilateral salpingo-oophorectomy specimens were performed. Perfusion index (PI) and oxygen saturation (O(2)Sat) measurements using a modified probe were taken at specified intervals at the uterine cornu during ten routine benign abdominal hysterectomies to assess the contribution of the ovarian and uterine vessels to overall uterine perfusion and the concepts studied were utilized in certain gynecological procedures. The ovarian/infundibulopelvic vessels course medially through the broad ligament toward the uterine cornu and consistently give off a branch to the ovary on its lateral border. In addition, further vessels were noted to run laterally from the uterine cornu along the ovarian ligament to the medial aspect of the ovary. PI and O(2)Sat measurements imply that the uterine and ovarian vessels contribute almost equally to uterine perfusion. Clinical application by selective ligation of the pelvic vasculature has been utilized in certain gynecological procedures often prone to torrential life-threatening uterine hemorrhage. Selective temporary ligation of the uterine and ovarian vessels has proven useful in the surgical management of chemoresistant gestational trophoblastic disease, in the Strassman procedure, fertility-sparing surgery in ruptured cornual ectopic pregnancies, and unrelenting postpartum hemorrhage. Of the six supplying vessels (ovarian, uterine, and vaginal) to the uterus only two (ovarian or uterine or a combination thereof) are required for uterine viability. 相似文献

Clinical symptoms and findings in cranial computed tomography (CT) were evaluated in 326 patients with intracerebral hemorrhage (ICH). Localizations of ICH were the lobes (n = 254), the basal ganglia (n = 46), the pons and brain stem (n = 13) and the cerebellum (n = 8). Multiple hematomas were present in nine patients. An initial coma (n = 225) was most frequent in ICH of the pons (n = 7), cerebellum (n = 6), and the frontal (n = 71) and temporal (n = 66) lobes. Epileptic seizures (n = 70) were most common in hematomas of the frontal (n = 24), temporal (n = 19) and parietal (n = 12) lobes and the basal ganglia (n = 6). A history of hypertension was given in 140 patients; 119 of these had an ICH with a size of ≥3 cm. Mortality (n = 162) was high with ICH in the pons and brain stem (10 out of 13), in the frontal (54 out of 98) and parietal (32 out of 58) lobes and the basal ganglia (n = 23). A size of the ICH of 3 cm or more in cranial CT and an associated ventricular hemorrhage were associated with a bad outcome. An initial disturbance of consciousness was the only reliable clinical predictor of outcome (chi-square, p < 0.001). Katamnestic evaluation of 66 of the 164 survivors after 5.2 years revealed seizures in 20 patients and mild neurological deficits in 41. Another 14 patients were partially, and nine totally dependent Nineteen patients had died in between; there was only one death attributable to another ICH. 相似文献
