Background: Novice trainees often face challenges in achieving proficiency in spinal anesthesia due to the technical complexities involved. Ultrasound-assisted methods have been proposed to enhance success rates and reduce complications in various medical procedures. However, its impact on spinal anesthesia performance by novice trainees remains unclear.Materials and Methods: In this retrospective comparative study, we analyzed the success rates of spinal anesthesia performed by novice trainees using both traditional and ultrasound-assisted methods. A total of 150 cases were included, with 75 cases in each group. Success rate, defined as the ability to achieve successful anesthesia on the first attempt, along with procedure time and incidence of complications, were compared between the two groups.Results: The success rate of spinal anesthesia in the ultrasound-assisted group was significantly higher compared to the traditional group (87% vs. 65%, p < 0.05). Additionally, the procedure time was shorter in the ultrasound-assisted group (mean ± SD: 6.2 ± 1.5 minutes) compared to the traditional group (8.5 ± 2.0 minutes). Complication rates were comparable between the two groups (5% in both groups).Conclusion: The ultrasound-assisted method significantly improves the success rate of spinal anesthesia performed by novice trainees while reducing the procedure time. Implementing ultrasound guidance in training programs may enhance the proficiency of novice trainees in performing spinal anesthesia.
