Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is whether preloading before positioning would be effective for less hemodynamic instability. The study also analyzes that patients with preloading will decrease postoperative nausea and vomiting, better surgical satisfaction and shortened the duration of surgery and anesthesia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Keeping patients in normovolemic state and hemodynamically stable in anesthesia and intensive care practice are important goals of anesthesiologist. It is known that hypotension that develops after taking patients to the beach chair position has a negative effect on cerebral oxygenation. Aggressive fluid regimes using to prevent hypotension can cause glycocalyx damage, edema and organ dysfunction. Also hypertension seconday to vasopressor therapy can cause bleeding at the surgical site and impaired surgical visualization during the arthroscopic shoulder surgery.

In the literature, there are studies examine whether the hypotension is the result of decreased cardiac output or decreased systemic resistance and what should be the optimal treatment , but as far as investigators know, there is no study about effects of preloading before the beach chair position on hemodynamic parameters.
