Clinical investigation of emergency cervical cerclage for uterine cervical incompetence patients in mid-trimester

Abstract

Objective To analyze the clinical characteristics of emergency cervical cerclage(CC) for uterine cervical incompetence(UCI) patients in mid-trimester. Methods From January 2014 to October 2015, a total of 16 cases of UCI patients in mid-trimester who were underwent emergency CC in Liuzhou Maternity and Child Healthcare Hospital were chosen as study subjects. According to whether the neonatal survived or not, the 16 patients were divided into fetus nonsurvival group(n=6) and fetus survival group(n=10). Retrospectively analyzed the general clinical data and prolongation of pregnancy after CC of all subjects, and the birth weight and outcome of newborns, etc.. The age, the number of previous intrauterine operations, the degree of cervical dilatation, the gestational age at CC and at delivery, the prolongation of pregnancy after CC and the birth weight of the newborns were compared between two groups by statistical method. This study has been approved by the Ethics Committee of Liuzhou Maternal and Child Healthcare Hospital. Results ①The average age of the 16 patients was (30.4±4.0) years old, the average number of previous intrauterine operations was (2.6±2.4) times, the average cervical dilatation at admission was (3.9±2.7) cm, mean gestational age at CC was (22.3±2.2) weeks and (29.4±6.3) weeks at delivery, the average prolongation of pregnancy after CC was (49.9±41.6) days, the average birth weight of survival newborns was (2.2±1.0) kg, and the fatality rate of fetus after birth was 37.5%(6/16). ②The maternal age and the number of previous intrauterine operations of the nonsurvival group were older or more than those of survival group, while the gestational age at delivery, prolongation of pregnancy after CC and neonatal birth weight were less than those of survival group, and the differences were statistically significant(P 0.05). Conclusion Maternal age and the number of previous intrauterine operations may affect the pregnancy outcomes in mid-trimester UCI patients with emergency CC treatment.
