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

- 50
- Primary Endpoint
- passive leg raising maneuver
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.

Outcomes
Primary Outcomes
passive leg raising maneuver
Time Frame: 2 minutes
Head of bed at 0 degrees flat and both legs elevated to 45 degrees
vena cava inferior diameter
Time Frame: 2 minutes
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.
Secondary Outcomes
- Blood pressure(2 minutes)
- Heart rate(2 minutes)
- End-tidal CO2(2 minutes)
- plethysmographic waveform(2 minutes)
