Objective. This work aims to analyze the surgical timing and clinical efficacy of transvaginal cervical ring ligation based on the ultrasound image focus detection of patients with cervical insufficiency (CIC) under the ultrasound image theme generation model. Methods. 134 CIC patients who came to the hospital for ultrasound imaging diagnosis were collected. Observation group was treated with cervical cerclage (CC) and the pregnancy outcome was followed up. Control group was treated conservatively. Results. For patients in the control group, average gestational age was 21.12 ± 2.18 weeks, average cervical length (CL) was 15.54 ± 0.42 mm, and average uterine opening width was 3.06 ± 0.63 mm. In the observation group, average gestational age was 24.45 ± 4.12 weeks, average CL was 17.32 ± 4.09 mm, and average uterine opening width was 0.21 mm. There were significant differences between the two groups ( P < 0.05 ). There were also significant differences in the degree of uterine orifice dilation between the two groups ( P < 0.05 ). Pregnancy outcomes of the two groups were compared, and χ2 and P < 0.05 indicated significant differences. Conclusion. Convolution neural network (CNN) and long short-term memory model (LSTM) algorithm were used to classify patients' ultrasound images, which could effectively improve diagnosis and treatment efficiency. Surgical success rate, clinical outcomes, neonatal survival rate, and clinical effect of observation group were better than those of control group. Cervical ligation was best performed before 17 weeks of pregnancy in CIC.

Purpose The objective of this study was to investigate the effectiveness of warm saline injection during PICC catheterization in preventing vasospasm and reducing mechanical phlebitis caused by vasospasm in tumor patients. Methods The study included 262 inpatients in the colorectal surgery department of our hospital who required PICC placement between January and December 2022. They were randomly divided into two groups, with the experimental group (n=132) receiving warm saline injection during catheterization and the control group (n=130) receiving conventional catheterization. The incidence of vasospasm, catheterization time, and mechanical phlebitis during PICC catheterization were compared between the two groups. Results The incidence of vasospasm in the experimental group was 1.52%, with 3.3% of patients taking more than 5 minutes to complete catheter delivery, and an incidence of mechanical phlebitis was 0.8%. In the control group, the incidence of vasospasm was 12.31%, with 15.3% of patients taking more than 5 minutes to complete catheter delivery, and an incidence of mechanical phlebitis of 9.2%. The difference between the two groups was statistically significant (P<0.05). Conclusion Warm saline injection during PICC catheterization can effectively prevent vasospasm during PICC catheterization, shorten catheterization time, and reduce the incidence of mechanical phlebitis in tumor patients. This method is simple and feasible and can be considered for clinical application.
