Correlation of the Dural Sac Dimension With the Spread of Spinal Anesthesia

Completed

• Conditions: Elderly Patients

• Registration Number: NCT04065763
• Lead Sponsor: SMG-SNU Boramae Medical Center

Brief 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.

Primary Outcome Measures

Name	Time	Method
Correlation between the dural sac dimension and spinal anesthesia spread (peak sensory block)	At 30 minutes after the induction of spinal anesthesia	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.

Secondary Outcome Measures

Name	Time	Method
Correlation between the dural sac dimension and duration of spinal anesthesia	At 30 minutes after the end of surgery	The sensory and motor regression are assessed. Then, the correlation between the dural sac dimension and the duration of spinal blockade is assessed.
Correlation between the dural sac dimension and body mass index	5 minutes before spinal anesthesia	Correlation between the dural sac dimension and body mass index is assessed.
Correlation between the dural sac dimension and waist circumference	5 minutes before spinal anesthesia	Correlation between the dural sac dimension and waist circumference is assessed.
Correlation between the dural sac dimension and age	5 minutes before spinal anesthesia	Correlation between the dural sac dimension and age is assessed.
