CLB or oxytocin (OTC) was given to the CLB group ( n =80) and the OTC group ( n =52) respectively. The third group served as controls ( n =29). The control group consisted of women experiencing natural labor and to whom no drug was given. The time of second stage of labor and prognosis of mother and newborn of different groups were observed and compared. And intrauterine pressure and fetal heart rate were monitored by means of electronic monitoring. Isolated uterine muscular tissue was used to observe the reactivity to CLB. The results showed that the time of second stage of labor and postpartum hemorrhage in the CLB group were less than those in the control group and the average intrauterine pressure in the former was higher than that in latter, so was the contraction strength of isolated uterine muscle, but with no difference as compared with the OTC group. No side effect of CLB was found. It is concluded that CLB could obviously strengthen uterine contraction and accelerate second stage of labor. Moreover, it is inexpensive, convenient and free of side effect. It can be used as a new, safe and effective alternative for improving prognosis of mother and newborn, especially those not indicated for oxytocin or profuse infusion.展开更多

Conclusions:Almost half of puerperas with the length of second stage of labor longer than 2 h underwent vaginal delivery.The prolonged second stage of labor can decrease the score of Apgar scale in 1 min,increase the incidence of asphyxia,but has no effect on scale in 5 min.It still need more evidence from evidence medicine to definition of time and treatment of second stage of labor.展开更多

We here attempted 1) to determine the obstetricians’ attitudes towards MUFP via questionnaire, and 2) to examine whether MUFP shortens the 2nd stage of labor, with the latter tested as a pilot study. Methods: A questionnaire-based study was carried out (n = 122) at meetings of Obstetrics on May 5, 2017. Then, we conducted a pilot case-control study from August 23 to September 6, 2020. Participants (n = 29) were divided into two groups;women who did and did not want MUFP;i.e., MUFP (n = 14) vs. (Non-MUFP) group (n = 15). Results: Of 122 doctors, 99.18% (121/122) used MUFP at cesarean section. 95.90% (117/122) of institutions used MUFP in spontaneous delivery. 95.08% (116/122) obstetricians considered MUFP effective and helpful. 85.24% (104/122) considered that MUFP should be employed after station +3. In the case control study, MUFP vs. Non-MUFP group showed the second-stage-duration of 58.5 (50.25 - 71.25) vs. 48 (39 - 59) minutes, without statistical significance (P = 0.101). However, importantly, MUFP, compared with Non-MUFP group, showed a significantly shorter duration from head visible on introitus (apparition) to delivery;i.e., 21.26 ± 7.32 vs. 30.13 ± 10.61 minutes (P = 0.014). Conclusions: MUFP is still used widely and MUFP shortened the duration of head apparition to delivery time. Larger-sample studies are needed to confirm the efficacy and safety of MUFP.展开更多

The objective is to audit the use of uterotonics in the active management of the third and fourth stages of labor. Methods: Personal data, diagnostic clinical information, blood loss and uterotonics administered were extracted from a cohort of 634 consecutive parturient. Trend in Shock Index (Pulse Rate/Systolic Blood Pressure) and 48 hours hematocrit changes were computed and analyzed. Results: There were 422 vagina deliveries and 212 caesarean sections. Primiparous mothers were 141 (34.2%), while grand multiparous mothers were 14 (3.4%). The mean visually estimated postpartum blood loss 165.9 ± 80 ml. There was no significant difference in the mean blood loss between the three parity groups of parturient [P = 0.09]. Fourteen parturient (3.44%) had blood loss ≥500 ml. The value of Shock Index (Pulse Rate/Systolic Blood Pressure) in the study ranged between 0.43 and 1.38. Logistic regression analysis of the variables associated with the switch between the three regimens of uterotonic drugs, showed a significant positive correlation between VEBL and uterotonic drugs administered [Pearson correlation = 0.130, P-value = 0.008]. In addition, there was a significant negative correlation between uterotonic drugs administered and Shock Index at 30 minutes and 2 hours postpartum. The correlation coefficient between VEBL and regimens of uterotonic drugs used was positive and significant (P = 0.019). Conclusion: Visually estimated blood loss, with shock are the main Triggers involved in switching between uterotonic drugs regimens used in active management of PPH. Shock index calculation is vital in management decision. We advocate training of all birth attendants on VEBL.展开更多

The author describes in this work 588 childbirth labors that took place without any medical supervision. Method: All patients who reached the hospital with a full cervix dilation were included in the study. The outcomes of those childbirth labors without medical supervision were evaluated at the maternal and neonatal level. Results and Discussion: The average age of the patients was 28.1 ± 13 years with 47% nulliparous and 30% pauciparous. These patients represented 14% of all births;59% of the patients had had three and five prenatal consultations. 71% of them came straight from home and had meconium-stained amniotic fluid. The APGAR score was greater than 6 in 94% of newborns, and 66.7 of them weighed between 2500 and 3500 g. Only 0.9% of patients coming from home needed a caesarean section. Conclusion: Home birth is not yet possible in Africa because it is not supervised by professionals who know the risks of childbirth, its complications and recognize the warning signs;however, the results of this preliminary study show that the issue of home childbirth in Côte d’Ivoire can be reconsidered subject to greater involvement of medical staffs.展开更多
