To explore the effect of noninvasive balloon abdominal pressure band on postpartum uterine contraction and postpartum hemorrhage in parturient women. Methods 96 full-term first trimesters who gave birth in the obstetrics department of our hospital from August 2020 to June 2021 were randomly divided into control group (n=48) and observation group (n=48). The mothers in the control group gave birth in the way of traditional delivery, during the third stage of labor, oxytocin 20 U+0.9% sodium chloride were given intravenously. The observation group was assisted by non-invasive balloon abdominal pressure band on the basis of traditional delivery. The time of labor, blood loss, postpartum uterine contraction, blood routine and coagulation indexes before and after delivery, and the blood gas value of umbilical artery at birth were compared between the two groups. Results Compared with the control group, the time of the third stage of labor, the time of placenta delivery, the amount of bleeding in the third stage of labor, the amount of bleeding from placenta, and the amount of bleeding in the 2h postpartum of the observation group were significantly reduced(P＜0.05). At 72 h postpartum, the magnitude of contractions, contraction intensity, contraction tension, RBC, Hct, Hb, and PLT of the observation group were significantly higher than those of the control group, and the frequency of contractions was significantly lower than that of the control group, the difference was statistically significant (P＜0.05). There was no statistically significant difference in the rate of lateral resection of the perineum, 2 h postpartum vital signs, and 72 h postpartum PT, APTT, and Fg between the two groups (P＞0.05).There was no significant difference in Apgar score and umbilical artery blood pH, PO2, PCO2, hematocrit and hematocrit between the two groups of newborns (P＞0.05). Conclusion Non invasive balloon abdominal pressure band combined with uterine contractions can enhance maternal uterine contractions, accelerate the third stages of labor and reduce postpartum blood loss, without affecting the health of mother and child, safe and reliable.
