Association of ultrasound-assisted combined with conventional anatomical landmark paramedian spinal anesthesia and its impact on first pass success rate in patients with lower limb fractures- A retrospective cohort study.

ABSTRACT:

Background

The association between ultrasound-assisted combined with conventional anatomical landmark paramedian spinal anesthesia regarding the first-pass success rate remains contentious. This study aims to clarify this relationship.

Methods

In this retrospective cohort analysis of 146 patients with lower limb fractures, patients were divided into two groups based on their spinal anesthesia technique:ultrasound-assisted combined with conventional anatomical landmark (median or paramedian). The primary endpoint was the first-pass success rate, while secondary endpoints included total procedure time and discomfort score. Recorded covariates encompassed sex, age, BMI, ASA class, preoperative preparation time, pre-injury physical activity, number of needle insertions, pain int
