    Summary
    This summary is machine-generated.

    Body weight, body surface area, body mass index, and body height are significant predictors of the depth to the epidural space. These anthropometric measurements are crucial for accurate epidural anesthesia administration.

    Area of Science:

    • Anesthesiology
    • Anatomy
    • Medical Imaging

    Background:

    • Epidural anesthesia is commonly used for procedures like extracorporeal shock wave lithotripsy.
    • Accurate landmark identification is critical for safe and effective epidural needle placement.
    • Patient anthropometrics may influence the depth to the epidural space.

    Purpose of the Study:

    • To investigate the correlation between various anthropometric parameters and the depth to the epidural space.
    • To determine if body weight, body surface area, body mass index, or body height are significant predictors of epidural depth.

    Main Methods:

    • A study involving 210 patients undergoing epidural anesthesia.
    • Measurement of patient anthropometrics including body weight, body surface area, body mass index, and body height.

  • Linear regression analysis to assess correlations with the measured depth to the epidural space.

    • Main Results:

    • Significant correlations were found between body weight (BW), body surface area (BSA), body mass index (BMI), and body height (BH) and the depth to the epidural space.
    • The strength of correlation followed the order: BW > BSA > BMI > BH.
    • Mean epidural depth was 4.77 cm for males and 4.25 cm for females, with an overall average of 4.61 cm.

    Conclusions:

    • Anthropometric factors including body weight, body surface area, body mass index, and body height significantly influence the depth to the epidural space.
    • These parameters are valuable for predicting the depth to the epidural space, aiding in procedural planning.
    • Understanding these relationships can enhance the safety and efficacy of epidural anesthesia administration.
