About this trial
The aim of this study is to evaluate the effects of non-pharmacological factors-such as age, sex, body mass index, paraspinal muscle mass, vertebral canal anatomy, patient positioning, and injection technique-on the duration of sensory and motor block in patients undergoing spinal anesthesia, and to investigate the potential relationships between these factors and block duration.

Treatment groups
Trial outcomes
Primary outcomes
Paraspinal mass measurement with ultrasound.
Ultrasonographic measurement of paraspinal muscle thickness (cm) and its association with duration of spinal block will be investigated.
Secondary outcomes
The spread of the spinal block
The speed of the sensational block will be measured after spinal anaesthesia performed. Time(minute) will be recorded when T10 level sensational block is achieved.
