Comparison of the lateral decubitus and beach chair positions in terms of their effects on airway pressure in arthroscopic shoulder surgery

Aim: The aim of this study was to investigate the effects of extravasated fluid on the airway pressure of the patients in differentsurgical positions.Material and Methods: This prospective observational study included 50 arthroscopic shoulder surgery patients (18-65 years) placedin lateral decubitus (Group L) and beach chair (Group B) positions under general anesthesia. Peak airway pressure (Ppeak) andinternal PEEP (iPEEP) measurements were recorded after intubation. The neck, chest, and shoulder circumferences were measuredbefore induction and after operation.Results: The increases in Ppeak and iPEEP values were not statistically significant between the groups (p> 0.05). The total amount ofirrigation fluid was significantly higher in Group L (p=0.042), not significantly correlated with Ppeak but positively correlated with thesurgery time (r=0.51099; p=0.001
