The effect of ginger and metoclopramide in the prevention of nausea and vomiting during and after surgery in cesarean section under spinal anesthesia.

OBJECTIVE: Postoperative nausea and vomiting is one of the most common side effects after anesthesia in surgeries, such as cesarean section. This study aimed to investigate the effect of ginger and metoclopramide in the prevention of nausea and vomiting during and after cesarean section. METHODS: This clinical trial was conducted on 180 patients aged 18-40 years who underwent cesarean section under spinal anesthesia. The first group received 10 mg of metoclopramide via intravenous injection (metoclopramide group), and the second group received 1 g of oral ginger (ginger group) half an hour before spinal anesthesia. The frequency and severity of nausea and vomiting during surgery and at 2, 6, 12, and 24 hours postoperatively were compared in both groups. To analyze the results, the t-test, chi-square test, and Mann-Whitney test were used. RESULTS: There was no significant difference in the frequency of nausea and vomiting between the 2 groups during operation, 2 hours and 6 hours after surgery (P=0.182, 0.444 and 0.563 respectively). The severity of nausea and vomiting was also similar in the 2 groups (P=0.487 and 0.652 respectively); however, the metoclopramide group had a lower systolic blood pressure (P<0.001; df=2.176; f=18.66) and mean arterial pressure (P<0.001; df=2.176; f=6.36) than the ginger group. CONCLUSION: The results revealed that ginger reduced nausea and vomiting to the same extent as metoclopramide in patients undergoing cesarean section.

Effects of Topical Phenytoin Cream on Episiotomy Repair in Primiparous Women: A Double Blind Clinical Trial.

Episiotomy is the most prevalent obstetrical procedure with the purpose of either widening vaginal outlet or helping the fetus to deliver as soon as possible with the most feto-maternal safety. The aim of this study is to find out the effects of topical phenytoin cream on wound repair in primiparous women. One-hundred-thirty primiparous mothers were referred to Kowsar Hospital in Qazvin province participated in this clinical trial. Sixty-five participants were assigned in each of intervention and control groups. The intervention group was treated with topical 1% Phenytoin cream and 10% povidone-iodine (betadine) solution and the control group received placebo and betadine solution. Wound irrigation with betadine was performed as the routine order in the hospital, three times daily and two centimeters of topical phenytoin or placebo cream, were applied to the wound twice daily. The rate of episiotomy repair was measured by REEDA index in the first 24 h, the fifth and the tenth puerperal day. Data analyses were done t-test and chi-square test and Mann-Whitney. In the first 24 h, it was 6.43 ± 2.15 in the intervention group versus 6.52 ± 5.09 in the control group with no significant difference. However on The 5th day, it appeared 4.56 ± 3.01 in the intervention group versus 6.54 ± 2.98 in the control group (p < 0.001), likewise it was 5.82 ± 2.83 in the control group on the tenth day (p < 0.001). Significant difference was detected both in the 5th and 10th postpartum days. The result of this trial suggested that 1% phenytoin cream speeds-up the wound healing process; therefore it could be applied for accelerating episiotomy repair.

Level of maternal triglycerides is a predictor of fetal macrosomia in non-obese pregnant women with gestational diabetes mellitus.

BACKGROUND: The role of maternal serum triglycerides (TGs) in the development of fetal macrosomia in different subgroups of body mass index (BMI) has received little attention. The aim of this study was to determine the association between the level of maternal TGs and fetal macrosomia in Iranian pregnant women of different BMI subgroups with gestational diabetes mellitus (GDM). METHODS: This cohort study was conducted on 305 pregnant women with GDM referred for glucose control to Kowsar Hospital in Qazvin, Iran. Level of TGs was measured on the 24th-28th weeks of pregnancy. The ROC curve of the level of TGs was depicted in BMI subgroups to predict fetal macrosomia. Logistic regression analysis was used to determine the risk of macrosomia per 1-SD increase in the level of TGs. RESULTS: The prevalence of hypertriglyceridemia did not significantly differ across BMI subgroups. Macrosomia was more prevalent in obese women (32.2%) than overweight (19.1%) and normal weight (11.1%) women (P < 0.05). A 1-SD increase in the level of TG was associated with 4.2 and 1.9 times increased risk of macrosomia in normal weight (P < 0.01) and overweight (P < 0.01) women, respectively. Serum level of TGs was not associated with macrosomia in any adjustment models in obese women. The area under the curve of the level of TGs for macrosomia was 0.828 (95% CI: 0.712-0.911, P < 0.001) and 0.711 (95% CI: 0.639-0.775, P < 0.001) in normal weight and overweight women, respectively. CONCLUSION: Hypertriglyceridemia was a predictor of macrosomia in non-obese women. More studies on different ethnicities and lifestyles are necessary to determine the association between the level of maternal TG and fetal macrosomia in BMI subgroups.

Effect of Intravenous Dexamethasone on Preparing the Cervix and Labor Induction.

The use of corticosteroids is one of the methods put forward for the strengthening and speeding up the process of labor. After identification of glucocorticoid receptors in human amnion, the role of corticosteroids in starting the process of labor has been studied in numerous studies. The purpose of this study was to determine the effect of intravenous Dexamethasone on preparing the cervix and on labor induction. A randomized, clinical, and double-blind trial was conducted on 172 women divided into a control and an experimental group. The inclusion criteria were that they had to be primparous, in or before the 40th week of pregnancy, and with Bishop scores (B.S.s) of 4 or lower. The exclusion criteria were diabetes, preeclampsia, macrosomia, twin pregnancy, rupture of the membrane (ROM), breech, and women suffering from background diseases. The B.S.s of the women was measured in charge of the study, and each woman was intravenously injected with eight milligrams of Dexamethasone or eight milligrams of distilled water. Four hours after the injections, the B.S.s of the participants was measured, and they were put under the conditions of labor induction using oxytocin. Information was collected in checklists A and B. The patients were compared with respect to B.S., the time the induction started, the average interval between the start of induction and the beginning of the active phase of childbirth, and the average length of time between the start of the active phase and the second stage of childbirth. The first and five minutes Apgar scores of the two groups of women were compared. The frequencies, the means, and the standard deviations were calculated using the SPSS - 16 software, and analysis of the results was performed with the Student's t- test and the chi-square test with with P<0.05. There were no statistically significant differences between the two groups in terms of their age, period of pregnancy, and B.S. at the start of the study. The average B.S. of women four hours after the injections with Dexamethasone was 5.9 ± 1.57, and the corresponding figure for women in the control group was 4.6 ± 1.72. These figures were significantly different at P<0.001. The average interval between labor induction and the start of the active phase in the group injected with Dexamethasone was significantly less than that of the control group (2.87±0.93 versus 3.80± 0.93 at P<0.001). The average duration of the active phase of the second stage of childbirth was 3.47±1.10 hours in the experimental group and 3.6 ± 0.99 hours in the control group at P<0.49. These two figures were not significantly different. The Apgar scores of the first and fifth minutes after the birth of the children of the two groups of women were not significantly different. It was found that intravenous Dexamethasone improves the Bishop score of the cervix and thus causes softening of the cervix and reduces the length of time between labor induction and the start of the active phase of childbirth.

Effect of treatment of vitamin D deficiency and insufficiency during pregnancy on fetal growth indices and maternal weight gain: a randomized clinical trial.

OBJECTIVE: To determine whether treatment of low serum vitamin D in pregnant women improves fetal growth indices. STUDY DESIGN: In this open-label randomized clinical trial, 130 Iranian pregnant women (24-26 weeks of gestation) with vitamin D deficiency or insufficiency [25(OH)D <30ng/ml] were divided at random into an intervention group and a control group. The control group received 200mg calcium plus a multivitamin (containing vitamin D3 400U) each day, and the intervention group received 200mg calcium plus a multivitamin (containing vitamin D3 400U) each day, plus vitamin D3 (50,000U) each week for 8 weeks. At delivery, maternal and cord blood 25(OH)D levels, maternal weight gain, neonatal length, neonatal weight and neonatal head circumference were compared between two groups. Serum vitamin D was measured using enzyme-linked immunosorbent assay. A multivariate regression analysis was performed to examine the independent effect of maternal vitamin D level on fetal growth indices. RESULTS: Mean (±standard deviation) length (intervention group: 49±1.6cm; control group: 48.2±1.7cm; p=0.001), head circumference (intervention group: 35.9±0.7cm; control group: 35.3±1.0cm; p=0.001) and weight (intervention group: 3429±351.9g; control group: 3258.8±328.2g; p=0.01) were higher in the intervention group compared with the control group. Mean maternal weight gain was higher in the intervention group compared with the control group (13.3±2.4kg vs 11.7±2.7kg; p=0.006). Multivariate regression analysis for maternal weight gain, neonatal length, neonatal weight and neonatal head circumference showed an independent correlation with maternal vitamin D level. CONCLUSION: Treatment of low serum vitamin D during pregnancy improves fetal growth indices and maternal weight gain.
