Brief summary
Combined spinal epidural anesthesia is commonly used for inguinal hernia repair in our institution. to increase patient safety and success rate of combined spinal epidural anesthesia and also decrease the incidence of probable complications related to regional anesthesia technique, the use of ultrasound guidence is increasing among anesthesiologists. ultrasound enables the accurate localisation of the intervertebral space for puncture site and also helps the practiotioner safely introduce the epidural needle to a certain depth. the correlation of epidural depth measured with ultrasound and some patient variables were studied in the literature but the current study is unique in studying the correlation between abdominal girth and epidural depth measured with ultrasound at saggital paramedian oblique plane and transverse plane.
Interventions
after patient is accepted to the operation room and monitorized according to american society of anesthesiologists standards, age, height, weight, vertebral column length and abdominal girth of the patients will be recorded. vertebral column length will be measured using a tape meter starting from the spinous process of 7th cervical vertebra to sacral hiatus. abdominal girth will be measured using a tape meter at the level of umblicus. an anesthesiologist experienced in sonoanatomy will examin the lumbar epidural depth of the patient with convex probe at transverse plane and sagittal paramedian oblique plane just before the start of surgery in a few minutes. the measurements will be recorded for each patient.
