NCT05537246

Brief Summary

The aim of this study is to investigate the importance of pulse wave velocity, an indicator of arterial stiffness, in predicting hemodynamic changes in normotensive and hypertensive patients undergoing spinal anesthesia.

Outcome Measures

Primary Outcomes (1)

  • Arterial blood pressure

    After spinal anesthesia, SBP, DBP, MAP, HR and SpO₂ values of all patients were recorded.

    1., 3., 5., 10., 20. minute

Study Arms (2)

GROUP HT

In the preoperative evaluation, after arterial blood pressure measurement was made 3 times; Hypertension group was defined as the patients who did not use drugs that are effective on the cardiovascular system, whose SBP value was higher than 140 mmHg, or those who were diagnosed with hypertension and were using drugs with a SBP value higher than 140 mmHg.

Procedure: PWV

GROUP NORMO

As a result of 3 measurements and medical histories of the cases, those who did not use drugs effective on the cardiovascular system and whose SBP value was lower than 140 mmHg were called the normotensive group.

Procedure: PWV

Interventions

PWVPROCEDURE

All cases were evaluated in the service before surgery. Pulse wave velocity measurement was performed with the MOBİL-O-GRAPH device, which is one of the noninvasive methods. Before measuring from patients; It was confirmed that there was no coffee/cigarette consumption within 30 minutes. After resting for 5 minutes in a quiet room, the cuff of the appropriate size was tied to the arm in such a way that it came to the brachial artery. The data recorded by the tonometer was transferred to the computer program. Care was taken that the patient did not move or talk during the measurement.
