Clinical Trial Summary

Cerebrospinal fluid volume is an important factor that influences peak block height and regression of sensory and motor blockade. The aim of this study is to evaluate the effect of dural sac dimension on the spread of spinal anesthesia in elderly patient using ultrasound.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation between the dural sac dimension and spinal anesthesia spread (peak sensory block)	The dural sac dimension is assessed before spinal anesthesia. After spinal anesthesia, the sensory and motor level are evaluated. Then, the correlation between the dural sac dimension and spinal anesthesia blockade is assessed.	At 30 minutes after the induction of spinal anesthesia
Secondary	Correlation between the dural sac dimension and duration of spinal anesthesia	The sensory and motor regression are assessed. Then, the correlation between the dural sac dimension and the duration of spinal blockade is assessed.	At 30 minutes after the end of surgery
Secondary	Correlation between the dural sac dimension and body mass index	Correlation between the dural sac dimension and body mass index is assessed.	5 minutes before spinal anesthesia
Secondary	Correlation between the dural sac dimension and waist circumference	Correlation between the dural sac dimension and waist circumference is assessed.	5 minutes before spinal anesthesia
Secondary	Correlation between the dural sac dimension and age	Correlation between the dural sac dimension and age is assessed.	5 minutes before spinal anesthesia
