Shoulder Surgery in the Beach Chair Position Associated with Diminished Cerebral Perfusion
Sub-headline: Study highlights potential risks of shoulder arthroscopy performed in beach chair position
Paragraph 1:
A recent study has found that shoulder arthroscopy performed in the beach chair position, where the patient is positioned with their head and neck elevated and their chest and abdomen positioned lower than their hips, is associated with diminished cerebral perfusion. The study, published in the journal Arthroscopy, highlights the importance of considering the potential risks of this surgical position when performing shoulder arthroscopy.
Paragraph 2:
The beach chair position is commonly used in shoulder arthroscopy due to the benefits it offers for visualization and access to the shoulder joint. However, the study's findings suggest that this position may lead to reduced cerebral blood flow, which can have implications for patient safety. The study included 40 patients undergoing shoulder arthroscopy in the beach chair position with general anesthesia. Researchers measured cerebral perfusion using near-infrared spectroscopy before, during, and after the surgery.
Paragraph 3:
The results showed that cerebral perfusion significantly decreased during the beach chair position compared to the supine position (where the patient is lying flat on their back). The decrease in cerebral perfusion was associated with the increased head and neck elevation in the beach chair position, which can lead to decreased venous return to the heart and reduced cerebral blood flow.
Paragraph 4:
The findings of this study emphasize the need for caution when using the beach chair position in shoulder arthroscopy. Surgeons should be aware of the potential risks associated with this position and take steps to mitigate these risks, such as using careful patient positioning and monitoring cerebral perfusion during the procedure.
