Clinical Trial Summary

The most used anatomical landmark for application of spinal anesthesia is Tuffier's line. Other alternative landmark is tenth rib. However there is no trial that compare these landmarks based on using ultrasonography.

Description:

The investigators aim to compare two landmarks (Tuffier's line and tenth rib line) for accuracy by using ultrasonography. 40 patients will be included in each groups. all of them will be assessed by ultrasonography during application of spinal anesthesia. And the investigators will examine the percentage of successful estimation of correct vertebral space.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	success of estimation the correct vertebral space	Independently, first anesthesist will determine the spinal anesthesia application point (intervertebral space) according to Tuffier's line and second anesthesist will determine it by ultrasonography. And third anesthesist will compare the accuracy of first determination.	2 months	No
