Objective

To construct the prediction model for intraoperative hypotension in cesarean section parturient,and to verify the predictive effect of the model.

Methods

A total of 245 pregnant women who underwent elective cesarean section in a tertiary grade A hospital in Shanxi province from December 2022 to December 2023 were selected as the research subjects.The parturient were divided into the normal blood pressure group and the hypotension group based on whether they experienced intraoperative hypotension.Logistic regression analysis was used to analyze the risk factors for intraoperative hypotension during cesarean section and to establish a risk prediction model.The sensitivity and specificity of the model were evaluated by using the area under the receiver operating characteristic(ROC) curve and the Hosmer-Lemeshow goodness-of-fit test.

Results

Among the 245 cesarean section patients,a total of 128 experienced intraoperative hypotension,with a prevalence of 52.24%.The results of Logistic regression analysis showed that the maternal's post-pregnancy body mass index,uterine height,sensory block plane,and abdominal circumference were the risk factors for intraoperative hypotension in cesarean section parturients.The risk prediction model was drawn.The area under the ROC curve(AUC) of this model was 0.918,with a sensitivity of 0.904 and a specificity of 0.872.The Hosmer-Lemeshow test showed a good fit.

Conclusion

The established prediction model for intraoperative hypotension in cesarean section parturient has a good predictive effect.It could provide reference for clinical identification of risks and timely implementation of preventive intervention measures.

目的

构建剖宫产产妇术中低血压发生预测模型,并验证模型的预测效果。

方法

选取2022年12月—2023年12月在山西省某三级甲等医院行择期剖宫产手术的245例产妇为研究对象。根据产妇术中是否发生低血压分为正常血压组及低血压组,通过Logistic回归分析探讨剖宫产术中发生低血压的危险因素,建立风险预测模型。通过受试者工作特征(ROC)曲线下面积、Hosmer-Lemeshow拟合优度检验评价模型的灵敏度和特异度。

结果

245例剖宫产产妇中128例发生术中低血压,发生率为52.24%。Logistic回归分析结果显示,剖宫产产妇孕后体质指数、宫高、感觉阻滞平面及腹围是其发生术中低血压的危险因素。绘制风险预测模型,该模型ROC曲线下面积(AUC)为0.918,灵敏度为0.904,特异度为0.872。Hosmer-Lemeshow检验结果显示拟合优度较好。

结论

构建的剖宫产产妇术中低血压预测模型具有较好的预测效果,可为临床识别风险、及时采取预防性干预措施提供参考。

目的

构建剖宫产产妇术中低血压发生预测模型,并验证模型的预测效果。

方法

选取2022年12月—2023年12月在山西省某三级甲等医院行择期剖宫产手术的245例产妇为研究对象。根据产妇术中是否发生低血压分为正常血压组及低血压组,通过Logistic回归分析探讨剖宫产术中发生低血压的危险因素,建立风险预测模型。通过受试者工作特征(ROC)曲线下面积、Hosmer-Lemeshow拟合优度检验评价模型的灵敏度和特异度。

结果

245例剖宫产产妇中128例发生术中低血压,发生率为52.24%。Logistic回归分析结果显示,剖宫产产妇孕后体质指数、宫高、感觉阻滞平面及腹围是其发生术中低血压的危险因素。绘制风险预测模型,该模型ROC曲线下面积(AUC)为0.918,灵敏度为0.904,特异度为0.872。Hosmer-Lemeshow检验结果显示拟合优度较好。

结论

构建的剖宫产产妇术中低血压预测模型具有较好的预测效果,可为临床识别风险、及时采取预防性干预措施提供参考。

Objective

To construct the prediction model for intraoperative hypotension in cesarean section parturient,and to verify the predictive effect of the model.

Methods

A total of 245 pregnant women who underwent elective cesarean section in a tertiary grade A hospital in Shanxi province from December 2022 to December 2023 were selected as the research subjects.The parturient were divided into the normal blood pressure group and the hypotension group based on whether they experienced intraoperative hypotension.Logistic regression analysis was used to analyze the risk factors for intraoperative hypotension during cesarean section and to establish a risk prediction model.The sensitivity and specificity of the model were evaluated by using the area under the receiver operating characteristic(ROC) curve and the Hosmer-Lemeshow goodness-of-fit test.

Results

Among the 245 cesarean section patients,a total of 128 experienced intraoperative hypotension,with a prevalence of 52.24%.The results of Logistic regression analysis showed that the maternal's post-pregnancy body mass index,uterine height,sensory block plane,and abdominal circumference were the risk factors for intraoperative hypotension in cesarean section parturients.The risk prediction model was drawn.The area under the ROC curve(AUC) of this model was 0.918,with a sensitivity of 0.904 and a specificity of 0.872.The Hosmer-Lemeshow test showed a good fit.

Conclusion

The established prediction model for intraoperative hypotension in cesarean section parturient has a good predictive effect.It could provide reference for clinical identification of risks and timely implementation of preventive intervention measures.

据世界卫生组织(WHO)报告,我国剖宫产率逐年增加[1-2]。剖宫产技术逐渐成熟,剖宫产术中维持产妇循环稳定是保障母婴安全的重要前提。脊髓麻醉因具有疗效确切和安全性较高等特点,是剖宫产手术的首选麻醉方式[3-4]。但因产妇妊娠期间特殊的生理、病理改变使产妇在剖宫产手术中接受脊髓麻醉后发生低血压的概率高达73.3%[5-6]。剖宫产术中低血压可致孕妇恶心、呕吐,甚至昏迷、呼吸麻痹等严重不良后果[7]。制定合理、有效的预防措施预防产妇在剖宫产术中发生低血压很有必要。因此,长期以来临床医护人员一直致力于探索剖宫产术中发生低血压的风险因素。目前,关于引起剖宫产手术过程中低血压发生的因素众多[8-9],国内外研究多局限于探讨剖宫产术中低血压影响因素,而缺乏低血压风险识别工具,不利于护理人员进行特征性风险识别而采取针对性的护理干预措施[10-12]。鉴于此,本研究拟构建剖宫产术中发生低血压的风险预测模型,为识别高危病人、及时采取预防性干预措施提供参考。
选取2022年12月—2023年12月在山西省某三级甲等医院行择期剖宫产术的245例产妇为研究对象,所有产妇均由同一组产科医生和麻醉医生进行剖宫产手术。纳入标准:1)均进行择期剖宫产手术;2)足月单胎妊娠;3)麻醉方式均为脊髓麻醉。排除标准:1)合并妊娠疾病;2)合并胎盘前置或胎盘早剥;3)存在脊髓麻醉禁忌证;4)合并HELLP综合征(溶血、肝酶升高、血小板减少);5)合并妇科肿瘤。本研究已获得山西医科大学第一医院伦理委员会审批(审批号:NO.KYLL-2023-005)。
收集所有产妇的基本资料,包括一般资料、产科资料及麻醉资料。1)一般资料:包括年龄、身高、孕前体重、孕后体重(孕38周)、孕期体重增加量、孕前体质指数和孕后体质指数、孕次、产次、瘢痕子宫、腹部形状;2)产科资料:包括孕周、羊水量、宫高、腹围、胎儿预测体重等;3)麻醉资料:包括禁食时间、麻醉前补液总量、麻醉操作过程侧卧时间、麻醉后至手术开始时间、麻醉后至胎儿娩出时间、感觉阻滞平面等。
采用SPSS 22.0软件进行统计分析。符合正态分布的定量资料以均数±标准差(x±s)描述,组间比较采用独立样本t检验;不符合正态分布的定量资料以中位数(四分位数)[M(P25,P75)]表示,组间比较采用Mann-Whitney秩和检验。定性资料用例数、百分比(%)表示,采用χ2检验或Fisher精确概率法。采用二元Logistic回归分析筛选独立危险因素,并构建剖宫产术中发生低血压的风险预测模型。采用受试者工作特征(ROC)曲线下面积(AUC)评价模型区分度,Hosmer-Lemeshow(H-L)χ2检验评价模型的灵敏度、特异度,验证模型的实际应用效能。以P<0.05为差异有统计学意义。
245例产妇中有128例在剖宫产手术过程中发生低血压,发生率为52.24%。根据术中是否发生低血压分为正常血压组和低血压组,两组发生低血压影响因素的单因素分析结果见表1。
以剖宫产产妇术中是否发生低血压为因变量(未发生=0,发生=1),将单因素分析中有统计学意义的项目(孕后体重、孕后体质指数、瘢痕子宫、孕期体重增加、孕期体质指数增加、宫高、腹围、胎儿预测体重、感觉阻滞平面)为自变量,进行Logistic回归分析。结果显示,孕后体质指数、宫高、感觉阻滞平面及腹围是剖宫产产妇术中发生低血压的危险因素(P<0.05)。自变量赋值方式见表2,多因素分析结果见表3。
根据回归系数与常数项得出预测模型的表达方程为:Logit(P)=0.331×孕后体质指数+0.976×宫高+ 1.365×感觉阻滞平面+0.097×腹围-1.473。ROC曲线下面积为0.918[95%CI(0.864,0.961),P<0.001];灵敏度为0.904,特异度为0.872。Hosmer-Lemeshow χ2检验结果显示,P=0.618,见图1。
随着剖宫产技术逐渐成熟,剖宫产手术量亦随之上升,但产妇在手术过程中的安全问题始终是临床重点关注的问题[13]。脊髓麻醉因效果确切、镇痛、肌肉松弛作用好等被广泛应用于剖宫产手术[14-15]。但是脊髓麻醉也存在诸多风险,其中术中低血压是常见的并发症[16-18]。剖宫产术中低血压可使产妇出现恶心、呕吐、头晕甚至晕厥等,也可使子宫胎盘灌注降低导致胎儿氧合受损、胎儿酸中毒、Apgar评分降低,危及母婴安全。剖宫产术中发生低血压由多方面因素共同导致,既往对剖宫产术中低血压预测因素的研究主要集中在产妇一般资料及麻醉因素等方面,但目前关于决定产妇术中低血压发生的因素暂无定论。目前国内研究多局限于对剖宫产术中低血压影响因素的探讨,缺乏风险评估工具用于指导临床医护人员识别高风险人群[19-20]。建立有效的预测模型是预防剖宫产术中发生低血压的重要手段[21]。围术期护理工作中应重点关注高风险产妇,给予有效的围术期预防护理策略。
本研究结果显示,245例剖宫产产妇中128例发生术中低血压,发生率为52.24%。本研究构建的风险预测模型ROC曲线下面积为0.918[95%CI(0.864,0.961),P<0.001];灵敏度为0.904,特异度为0.872。Hosmer-Lemeshow χ2检验结果显示,P=0.618。研究表明,胎儿对母体的血压下降较为敏感,低血压持续超过2 min即可对胎儿产生不良影响,造成胎儿缺氧、高碳酸血症和酸中毒[22]。因此,剖宫产术中积极干预以预防低血压发生远比被动处理低血压症状更为重要,通过对低血压风险的评估和预测,可使护理干预更为主动,更具针对性。
本研究结果显示,孕后体质指数>28 kg/m2、宫高>36 cm、感觉阻滞平面≥T6及腹围>100 cm是剖宫产产妇术中发生低血压的危险因素(P<0.05)。妊娠期体质指数与脑脊液容量有关,且体质指数较高的产妇硬膜外腔血管血流饱满,在大量脂肪堆积后可致硬膜外腔狭窄,引发剖宫产术中低血压[23]。妊娠后期增大的子宫对大血管的压迫是产生低血压的重要因素之一,子宫越大,压迫的可能性越大[24]。麻醉状态下交感神经阻滞被证实是剖宫产术中低血压的主要机制,麻醉阻滞平面越高,发生低血压的风险越高[25]。本研究进一步证实感觉阻滞平面≥T6是发生术中低血压的危险因素,提示尽量将阻滞平面控制在 T6 以下,以减少产妇在剖宫产手术中的循环波动。
本研究构建的风险预测模型预测效果较好,可为临床及早识别剖宫产术中发生低血压及实施针对性预防提供参考,且剖宫产产妇孕后体质指数、宫高、腹围、感觉阻滞平面≥T6是剖宫产术中发生低血压的危险因素。但本研究尚存在一定局限性,因本研究为回顾性研究,并不能得出确切的因果联系,且样本量相对较小,需要进一步验证风险预测模型的效果。
