Anesthesia, Spinal Clinical Trial
Official title:
The Effect of Spinal Anesthesia Methods on Hemodynamics in Geriatric Patients
In this study, it was planned to provide more stable hemodynamics in geriatric patients with low-dose spinal anesthesia. We will compare 7.5mg hyperbaric bupivacaine with 5mg hyperbaric bupivacaine. The researchers hypothesized that low-dose bupivacaine would provide adequate anesthesia, less hypotension, and faster recovery.
Hypothesis It is hypothesized that low-dose bupivacaine can provide adequate anesthesia, less hypotension, and faster recovery. patient population Patients over 65 years of age who will undergo spinal anesthesia due to hip fracture. Hemodynamic data(Blood pressure-mmHg, heart rate-beats per minute) of patients, bromage scores, perfusion index (PI) values, discharge time, pain with NRS (numerical rating scale), patient satisfaction will be evaluated ( Numeric output from 1-10). Hemodynamic variables will be recorded every 2 minutes in the first 20 minutes after spinal anesthesia. hemodynamic variables will be recorded 30 minutes after spinal anesthesia and at the end of the operation. The perfusion index is the ratio of the blood volume to the pulsatile to non-pulsatile fraction. An increase in the pulsatile fraction that occurs during vasodilation corresponds to a higher PI. Therefore, patients with a higher PI have a higher risk of post-spinal hypotension. ;
