Hemodynamic Changes With Passive Leg Raising Maneuver in Patients Undergoing Arthroscopic Shoulder Surgery

Study Overview
=================
Brief Summary
-----------------
After intubation of the patients who are undergoing arthroscopic shoulder surgery, plethysmographic waveform will be recorded with blood pressure, heart rate and end-tidal carbon dioxide values and inferior vena cava (IVC) diameter will be measured by ultrasound. New hemodynamic values will be measured after passive leg raising maneuver. Blood pressure, heart rate, end-tidal carbon dioxide values will be re-measured and plethysmographic waveform will be recorded after beach chair position for surgery.

Detailed Description
-----------------
Patients aged between 18-65 years who are undergoing arthroscopic shoulder surgery will be examined. After giving detailed information, voluntary certificate will be taken from patients who accept to participate in the study. Heart rate, oxygen saturation and blood pressure values will be recorded by routine monitoring. After intubation of the patients, plethysmographic waveform will be recorded with blood pressure, heart rate and end-tidal carbon dioxide values and IVC diameter will be measured by ultrasound. New hemodynamic values will be measured after passive leg raising maneuver. Blood pressure, heart rate, end-tidal carbon dioxide values will be re-measured and plethysmographic waveform will be recorded after beach chair position for surgery.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Procedure: vena cava inferior diameter measurement|Ultrasound equipment with convex probe will be used to measure IVC diameters of the patients in supine position.The IVC sagittal section is described with the probe in the area of subxiphoid. IVC diameters at the junction point of the IVC and right atrium (2cm caudal) are standardized measurement.|
