This prospective observational study aims to investigate about the efficacy of spine ultrasound in predicting difficult spinal anesthesia
Study Type
OBSERVATIONAL
Enrollment
100
Spinal Ultrasound is performed by an observer who records ultrasound characteristics of the intervertebral space chosen by the anesthetist who will practice spinal anesthesia
Spinal anesthesia is performed by an anesthetist after the observer recorded ultrasound characteristics of the intervertebral space chosen by the anesthetist, who is blinded to the ultrasound evaluation.
