Objective: To study the clinical value of three-dimensional ultrasound volume contrast imaging combined with free anatomy section in the diagnosis of intrauterine adhesions. Methods: 321 patients with suspected intrauterine adhesions admitted to Suzhou High-tech Zone People’s Hospital from July 2024 to July 2025 were selected. 94 cases were confirmed by hysteroscopy gold standard. All patients underwent separate examination of three-dimensional ultrasound volume contrast imaging (single examination) and a combined diagnosis scheme with free anatomy section (hereinafter referred to as combined diagnosis). The detection situation was analyzed, the diagnostic efficacy was calculated, and the results were compared with the gold standard to evaluate the advantages of combined diagnosis in disease classification. Results: The sensitivity and accuracy of the combined diagnosis were better than those of the single examination (P < 0.05). However, there was no significant difference in the detection rate of disease types between the two schemes (P > 0.05). Conclusion: The combination of three-dimensional ultrasound volume contrast imaging and free anatomy section can play a significant role in the diagnosis and classification of intrauterine adhesions, greatly improving the clinical detection rate.

Clinical Observation of the Effect of Sodium Ion Concentration on the Test Dose of Lidocaine in Patients Undergoing Epidural Block Cesarean Section

Objective: To investigate the effect of changes in sodium ion concentration on the onset time of lidocaine in obstetric epidural block test doses. Methods: Eighty pregnant women scheduled for elective cesarean section, with no age or weight restrictions and ASA grade I or II, were selected. Lidocaine was diluted to two concentrations of 1% and 1.5% using normal saline (NS) and sterile water for injection (SW). The patients were randomly divided into four groups (n = 20): Group A (1% SW), Group B (1% NS), Group C (1.5% SW), and Group D (1.5% NS). A 3 mL test dose of epidural block was administered. The onset time, sensory and motor block levels, and adverse reactions were observed in each group. Results: The onset time was slowest in Group A (mean onset time 4.79 ± 0.65 minutes) and fastest in Group D (mean onset time 3.59 ± 0.61 minutes). Comparison between groups showed that the onset time was significantly shorter in Group B compared to Group A (P < 0.05), but there was no significant difference compared to Group C (P > 0.05). Group C had a faster onset time compared to Group A (P < 0.05), but a slower onset time compared to Group D, with a statistically significant difference. Group D had the fastest onset time, which was statistically significant compared to the other three groups. There were no significant differences in sensory and motor block levels or adverse reaction rates between the four groups (P > 0.05). Conclusion: Compared to sterile water for injection, diluting lidocaine with normal saline can shorten the onset time of the test dose. The 1.5% normal saline group had the shortest onset time, which is related to the increased sodium ion concentration in the solution, thereby reducing the onset time of lidocaine.
