Comparison of Spinal Anesthesia and Erector Spinae Plane Block in Critically Adult Patients Undergoing Femur Surgery

The goal of this observational study is to compare the regional anesthetic methods (not including general anesthesia) -spinal anesthesia, erector spinae plane (ESP) block- which are in routine practice in critically ill adult patients operated for femur fracture, in terms of intraoperative and postoperative hemodynamics and clinical course, postoperative intensive care unit stay and hospitalization durations, pain scores, postoperative morbidity, and mortality.

Inclusion Criteria: * Agree to participate in the study * Patients older than 65 years of age who are planning to undergo an operation for a femur fracture and who are in the ASA III and above risk group and for whom postoperative intensive care unit follow-up is foreseen * Patients who agree to be operated under regional anesthesia Exclusion Criteria: * Patients who did not want to be included in the study * Patients considered suitable for operation under general anesthesia * Patients allergic to bupivacaine * Patients with contraindications to neuraxial blockage (infection at the injection site, coagulopathy or other bleeding diathesis, severe hypovolemia, increased intracranial pressure, severe aortic stenosis, severe mitral stenosis)
