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.

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.
Time frame: At 30 minutes after the induction of spinal anesthesia
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.
Time frame: At 30 minutes after the end of surgery
Correlation between the dural sac dimension and body mass index
Correlation between the dural sac dimension and body mass index is assessed.
Time frame: 5 minutes before spinal anesthesia
Correlation between the dural sac dimension and waist circumference
Correlation between the dural sac dimension and waist circumference is assessed.
Time frame: 5 minutes before spinal anesthesia
Correlation between the dural sac dimension and age
Correlation between the dural sac dimension and age is assessed.
Time frame: 5 minutes before spinal anesthesia
