Abstract
Background:Hypotension is one of the common complications of spinal anesthesia. Ephedrine with sympathomimetic effects is the selective vasopressor in obstetric. The aim of this study was to compare the effect of different doses of ephedrine on hypotension due to spinal anesthesia.
Materials and Methods: This randomized double-blind clinical trial included 120 parturient patients with ASA Ι and П scheduled for cesarean section under spinal anesthesia at Fatemy Hospital of Hamedan in 2008.The patients were divided into three groups. Immediately after spinal anesthesia, the patients randomly received 10 mg ephedrine, 20 mg ephedrine, or placebo intravenously. Then vital signs were recorded every minute for 5 minutes and after delivery every 10 minutes till the end of the surgery.
Results: Incidence of hypotension in 10 mg ephedrine, 20mg ephedrine, and placebo groups was 37.5,12.5, 85%, respectively (P<0.001 ). The difference in the prevalanceof hypotension was significant between the three groups (P<0.05).Based on Chi2 test, the prevalence of hypotension in 20 mg ephedrine group was less than 10 mg ephedrine group, and in the 10mg ephedrine group it was less than the placebo group (P<0.05). Conclusion: Intravenous injection of 10mg and 20mg ephedrine to parturient patients undergoing cesarean section reduces the incidence of hypotension, though thisdecrease is more significant with 20 mg ephedrine.

Abstract
Abstract
Background: Ectopic pregnancy is a type of pregnancy in which implantation of zygote occurs out of the uterine cavity. One of the most important problems is bleeding. On the other hand, Plasminogen Activator Inhibitor-1(PAI-1) gene is one of the involved factors in unsuccessful pregnancies, and 4G/5G polymorphism is the most common changes of this gene. So, it is important to study the prevalence of these changes in this gene in women with ectopic pregnancy.
Materials and Methods: In this case-control study, 100 Iranian women with ectopic pregnancy and 101 Iranian women with the normal pregnancy were selected. After blood sampling, ARMS PCR method has been used for detection 4G/5G polymorphism and data were analyzed by statistical analysis.
Results: In this study, 4G allele with 70.79% prevalence and 5G allele with 63.5% prevalence are the most common alleles for the control and case group, respectively. 4G/4G and 4G/5G genotypes in the control group and 4G/5G and 5G/5G genotypes in the case group are prevalent. An Armitage test found p<0.05 for both alleles, showing 4G allele (p= 1.524e-10; OR= 0.262) has decreasing effect and 5G allele (p= 1.524e-10; OR= 3.822) has increasing effect in ectopic pregnancy.
Conclusion: According to the findings, 5G allele and 4G/5G and 5G/5G genotypes have increasing effect, 4G allele and 4G/4G genotype have decreasing effect in ectopic pregnancy. So, we could consider 5G allele as a risk factor of ectopic pregnancy in this study.
