An observational study in Hypotension, sponsored by Chung-Ang University Hosptial, Chung-Ang University College of Medicine. Status unknown at 1 site in Korea, Republic of. Open to participants aged 20 Years to 70 Years. Per ClinicalTrials.gov, last updated 2016-01-28.

The beach chair position for shoulder operation induces hypotension during general anesthesia. Hypotension is induced by decreased preload and contractility due to anesthesia. Masimo is a pulse oximetry which shows pleth variability index noninvasively. The pleth variability may predict the hypotension during beach chair position.
The beach chair position for shoulder operation induces hypotension during general anesthesia. Hypotension is induced by decreased preload and contractility due to anesthesia. Masimo is a pulse oximetry which shows pleth variability index noninvasively. The investigators put the masimo probe before general anesthesia and recorded the values before and after beach chair position, The values include arterial pressure, heart rate, blood pressure, perfusion index, pleth variability index.
The primary end point was the predictive value and threshold or pleth variability index for hypotension induced by the beach chair position. The occurrence of hypotension was counted by using vasopressor. The use of vasopressor was performed when mean blood pressure less than 65 mmHg or 20% of baseline.
The investigators planned to recruit 57 patients.
1,003 studies on the registry are indexed under Hypotension; 173 are open to participants now.
This study's planned enrollment of 57 is below the median of 84 across 294 observational studies indexed under Hypotension.
