Angiotensin Converting Enzyme as a Possible Biomarker to Predict Effect of Obstetric Anesthesia on Pregnant Women with COVID-19 Infection

摘要

We retrospectively investigated 68 parturients with or without COVID-19 undergone emergency cesarean section with combined spinal-epidural anesthesia(CSEA)from a single tertiary university hospital in Wuhan,China.The cases were divided into 2 groups:patients with COVID-19 pneumonia(Group 1)and cases without COVID-19 pneumonia(Group 2).The patients in Group 1 were later divided into 2 groups:patients with low-angiotensin converting enzyme(ACE)(Group 3)and patients with normal-ACE(Group 4).The ACE levels,blood pressure and anesthesia management between the patients of Group 1 and Group 2,Group 3 and Group 4 were recorded as the primary outcome.The secondary outcome included perioperative symptoms,laboratory parameters and vital signs.Compared with Group 2,the patients in Group 1 had different ACE level and lower blood pressure after CSEA.Compared with Group 4,the patients in Group 3 showed lower SBP after CSEA(127 vs.130 mm Hg,p=0.028),accompanied with more partus matures and younger age(28 vs.32 years,p=0.007).ACE may be a possible biomarker to predict the anesthesia effects on patients with COVID-19 infections undergoing emergency cesarean delivery.
