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

Evaluation of Volume Status by Passive Leg Removal Maneuver and Vena Cava Inferior Diameter Measurements Before the Position of Patients in Arthroscopic Shoulder Surgery

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.

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.
