Abstract:
Objective To study the correlation of uterine segment thickness and time limits for patients with prior cesarean section. Methods A total of 80 women with the first pregnancy after cesarean section in our hospital from April 2013 to February 2015,according to the interval of cesarean section and second pregnancy,were divided into group A (18 cases,interval ≤3 years),group B (23 cases,an in-terval of 3 to 6 years),group C (27 cases,an interval of 7 to 9 years),and group D (12 cases,the interval ≥9 years).The uterine segment thickness and the success rate of vaginal trial production were compared.Surgical failures underwent vaginal trial production due to cesarean section were observed.Results The uterine segment thickness values of group A and group B in were respectively (5.93 ±0.34)mm and (5.45 ±0.27)mm,which were significantly higher than group C (3.24 ±0.52)mm and group D (2.83 ±0.56)mm,the difference was statistically significant (P <0.05).The vaginal trial production success rates of group A and group B were respectively 88.89% (16 /18) and 78.26% (18 /23),which were significantly higher than group C 44.44% (12 /27)and group D 33.33% (4 /12)(P <0.05).The dos-age of oxytocin of group A was (35.34 ±4.32)mL,blood loss was (256.32 ±34.21)mL, The oxytocin hormone dosage of group B was (37.09 ±4.52)mL,blood loss was (260.11 ±35.53)mL,which were lower than those in group C and group D (P <0.05).The postpartum hemorrhage rate of group A,group B and group C was respectively 0(0 /2),20.00% (1 /5),33.33% (5 /15)lower than group D 87.50%(7 /8)(P <0.05).Conclusion Maternal uterus at cesarean section within 7 years about the degree of recovery are in good condition,the higher uterine segment thickness,this time period is good for subsequent pregnancy and childbirth.
