Guiding effect of central venous oxygen saturation combined with static arterial central venous-to-arterial carbon dioxide difference on fluid re-suscitation treatment of postpartum hemorrhage
Objective To investigate the guiding role of central venous oxygen saturation(ScvO2)combined with the central venous-to-arterial carbon dioxide difference(P[v-a]CO2)in fluid resuscitation treatment of postpartum hemorrhage(PPH).Methods Sixty patients with massive hemorrhage during cesarean section of placenta implantation and placenta previa ad-mitted to Jiangxi Maternal and Child Health Hospital from February 2022 to March 2023 were selected as the study objects,and divided into experimental group(n=30)and control group(n=30)according to random number table method.The control group received conventional liquid resuscitation intervention,and the experimental group received ScvO2 combined with P(v-a)CO2 monitoring index for resuscitation intervention.The volume reaching time,oxygenation index before and after flu-id resuscitation,6 h lactic acid clearance rate,24 h lactic acid clearance rate and complication rate of the two groups were compared.Results The volume reaching time of experimental group was shorter than that of control group,and the difference was statistically significant(P＜0.05).After fluid resuscitation for 6 and 24 h,the oxygenation index of the experimental group was higher than that of the control group,and the differences were statistically significant(P＜0.05).The 6 h lactic acid clearance rate and 24 h lactic acid clearance rate of experimental group were higher than those of control group,and the differences were statistically significant(P＜0.05).The total complication rate of experimental group(16.67％)was lower than that of control group(40.00％),and the difference was statistically significant(P＜0.05).Conclusion Monitoring ScvO2 and P(v-a)CO2 can guide fluid resuscitation of PPH.Fluid resuscitation under the monitoring of ScvO2 and P(v-a)CO2 can shorten the duration of fluid resuscitation,improve oxygenation index and lactate clearance rate,and reduce the incidence of complications.
