To analyze the clinical characteristics of acute diquat poisoning complicated by central nervous system injury (CNSI) and identify early risk factors, aiming to provide a theoretical basis for reducing mortality in diquat poisoning with CNSI.

Objective:To investigate the high risk factors,diagnostic accuracy of ultrasonography and pregnan-cy outcomes of umbilical cord wrapped around the neck for≥4 loops.Methods:The clinical data of 64 pregnant women with umbilical cord around the neck for≥4 loops(the group with umbilical cord around the neck≥4 loops)in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2011 to February 2024 were retrospectively analyzed.At the same time,80 cases with umbilical cord around the neck for 1-2 loops(the group with umbilical cord around the neck 1-2 loops)were randomly selected as the controls.General information,clinical manifestations,ultrasound diagnosis and other data of the two groups were collected.The risk factors of umbilical cord around the neck≥4 loops and diagnostic accuracy of ultrasonography were ana-lyzed with univariate and multivariate Logistic regression analysis,and the pregnancy outcomes were compared between the two groups.Results:①The incidence of pregnancy,abortion,delivery and history of cesarean sec-tion were lower in the group with umbilical cord around the neck ≥4 loops than those in the group with umbilical cord around the neck 1-2 loops.The incidence of consciously abnormal fetal movement,abnormal umbilical ar-tery systolic/diastolic(S/D)ratio,abnormal fetal heart rate monitoring(NST)and fetal distress were higher in the group with umbilical cord around the neck≥4 loops than those in the group with umbilical cord around the neck 1-2 loops,and the differences were statistically significant(P＜0.05).②Multivariate Logistic regression analysis showed that polyhydramnios and excessively long cord were independent risk factors for umbilical cord around the neck≥4 loops(OR＞1,P＜0.05).③When the time between ultrasound diagnosis and the operation was 2 days,the consistency rate between ultrasound diagnosis of umbilical cord around the neck≥4 loops and intrao-perative diagnosis was the highest,and the difference was statistically significant with＞3 days(46.2％vs.6.30％,P＜0.05).Compared with umbilical cord around the neck 3 loops,ultrasound diagnosis of umbilical cord loops around the neck at 4 or 5 loops had a higher consistency rate with intraoperative diagnosis,and the differ-ence was statistically significant(P＜0.05).④The incidence of premature delivery,neonatal asphyxia and admis-sion to neonatology in the group with umbilical cord around the neck ≥4 loops were higher than those in the group with umbilical cord around the neck 1-2 loops,and the difference was statistically significant(P＜0.05);and the gestational week and birth weight of newborns were significantly lower(P＜0.05).Conclusions:Polyhydramnios and excessively long cord are high risk factors for umbilical cord around the neck≥4 loops.The closer the ultra-sound diagnosis is to the time before cesarean section and the more times the umbilical cord is around the neck in ultrasonic diagnosis,the higher the diagnostic accuracy.Fetal outcomes with umbilical cord around the neck≥4 loops are worse.
