Dokuz Eylul University42 enrolled

Overview

Aim: The aim of the study; to investigate whether there is a relationship between body mass index (BMI), waist circumference, and abdominal subcutaneous adipose tissue and the skin-epidural space distance measured by USG.

The research was carried out in the block room in the preoperating room of Dokuz Eylül University Practice and Research Hospital and with 42 volunteer operating room workers aged between 18-59 years. Height, weight and waist circumference measurements were made with standard measuring instruments, and other measurements were completed by ultrasonography (USG) separately by an anesthesiologist and a radiologist. For ultrasonographic evaluation, left lateral decubitus, right lateral decubitus and in sitting position, skin-dural junction, skin-vertebra corpus, anterior complex distances, upper and lower SIAS levels were examined with convex probe as transverse median. In addition, abdominal subcutaneous fat thickness measurements were made with a linear probe in the supine position. The statistical correlations of all measurements were examined.

Outcomes

Primary Outcomes

We examined the relationships between body mass index calculated by measuring weight and height, subcutaneous fat tissue in the abdominal region and the skin-epidural space distance in the lumbar region; measured by ultrasound.

Unexpectedly low skin-epidural space distances can be seen even in individuals with high weight and fat content. For the targeted space between above the anterior superior iliac spine (ASIS) (estimated L3-L4) and below the ASIS, each patient was positioned in the left lateral, right lateral and then sitting positions, with a transverse-median approach performed by an anaesthetist followed by a radiologist. Skin-dural composite (SDC), skin-vertebral body and anterior complex (posterior longitudinal ligament) distance measurements were recorded separately. Subcutaneous abdominal fat thickness was measured using a linear probe of an ultrasound device (LOGIQ-E, GE Medical Systems, China) to ensure consistency. Measurements were taken at two points (right lateral, left lateral) 2 cm away from the umbilicus and recorded by averaging. Waist circumference was measured using a standard measuring tape at the navel level in all volunteers.
