The traditional Lamaze breathing technique has limitations. We analyzed the effect of our new warm and calm (WC) breathing pattern on the incidence of fetal intrauterine distress, emergency cesarean delivery, forceps-assisted delivery, episiotomy, third- and fourth-degree perineal tears, and postpartum hemorrhage. Pregnant women who underwent a labor trial at the Second Hospital of West China University of Sichuan University between January 2020 and November 2023 and practiced the WC breathing pattern (n = 28,369) were recruited as the study group and those who underwent routine labor and practiced the Lamaze breathing technique between January 2016 and December 2019 (n = 21,110) constituted the control group. The chi-square test was used to compare differences in the incidence of fetal intrauterine distress, emergency cesarean delivery, forceps-assisted delivery, episiotomy, third- and fourth-degree perineal tears, and postpartum hemorrhage between the two groups. The incidence of the aforementioned events was significantly lower in the study group than in the control group. P-values were all ˂0.05, indicating significant differences. The WC breathing pattern increases the chances of a labor trial for pregnant women; reduces the incidence of fetal intrauterine distress, emergency cesarean delivery, forceps-assisted delivery, episiotomy, third- and fourth-degree perineal tears, and postpartum hemorrhage; and promotes safe delivery.
传统的拉玛泽呼吸法存在局限性。我们分析了我们新的温暖平静（WC）呼吸模式对胎儿宫内窘迫、急诊剖宫产、产钳助产、会阴切开术、三度和四度会阴撕裂以及产后出血发生率的影响。2020年1月至2023年11月在四川大学华西第二医院进行分娩试验并采用WC呼吸模式的孕妇（n = 28369）被招募为研究组，2016年1月至2019年12月进行常规分娩并采用拉玛泽呼吸法的孕妇（n = 21110）构成对照组。采用卡方检验比较两组胎儿宫内窘迫、急诊剖宫产、产钳助产、会阴切开术、三度和四度会阴撕裂以及产后出血发生率的差异。研究组上述事件的发生率显著低于对照组。P值均˂0.05，表明差异有统计学意义。WC呼吸模式增加了孕妇进行分娩试验的机会；降低了胎儿宫内窘迫、急诊剖宫产、产钳助产、会阴切开术、三度和四度会阴撕裂以及产后出血的发生率；并促进了安全分娩。
