Description of intervention(s) / exposure
after acceptance of patient to the operation room and standard monitorisation, age, height, weight, vertebral column length, abdominal girth measurements will be recorded. abdominal girth will be mesaured using a tape meter at the level of umblicus. vertebral column length will be measured from the spinous process of 7th cervical vertebra to sacral hiatus. epidural depth will be measured by an anesthesiologist experienced in sonoanatomy at sagittal paramedian oblique plane and transverse plane in 15 minutes. the measured epidural depths will be recorded

Statistical methods / analysis
IBM SPSS ver 21.0 will be used to analyze the data collected. mean, standard deviation, frequencies, median will be used for the analysis of quantitative data. normal distribution of data will be analyzed by Kolmogorov- Smirnow and Shapiro Wilk tests. Spearman's rho correlation and Pearson correlation tests will be used to analyze the correlation between the epidural depth measured with ultrasound at saggital paramedian oblique plane and transverse plane and parturients' abdominal girth, age, body mass index, and vertebral column length.

Summary
Brief summary
combined spinal epidural anesthesia is commonly performed for cesarean section surgery at our institution. anatomical landmarks are often hard to localize in pregnant patient population. ultrasound navigation for combined spinal epidural anesthesia provides fast, easy and reliable intervertebral interspace localization together with decreasing the risk of introducing epidural needle from higher dermatomes above second lumbar vertebra which is a common risk when performed with conventional palpation technique. ultrasonographic examination of lumbar vertebra also provides knowledge about the depth of epidural space which preserves the clinican the knowledge that how deep he/she can introduce the needle within safety margins. several patient variables were investigated to affect the epidural depth mesured with ultrasound. up to our knowledge the current study is unique in studying the correlation between parturients' abdominal girth and the epidural depth measured at saggital paramedian oblique plane and transverse plane with ultrasound.
