Using Computed Tomography Scans and Patient Demographic Data to Estimate Thoracic Epidural Space Depth

Table 1

Patient anthropometric characteristics (n = 218).

Variable	Mean ± standard deviation	Min.	Max.	Median
Age at procedure	55.79 ± 17.48	18	88	56
Weight, kg	82.87 ± 19.50	42.00	166.00	81.80
Height, m	1.70 ± 0.11	1.45	1.95	1.71
BMI	28.55 ± 5.96	17.70	64.84	27.95
LOR, cm	5.80 ± 1.31	2.50	12.50	6.00
SES-CT, cm	5.01 ± 1.03	2.70	8.20	4.90

BMI, body mass index; LOR, loss of resistance measurement; SES-CT, skin to epidural space depth as measured by computed tomography.
