MEDIASTINOSCOPY: INTRAOPERATIVE COMPLICATIONS — watch the RIGHT radial pulse Mediastinoscopy provides access to the superior mediastinum for lymph-node biopsy/staging, but the scope operates close to major vessels, airway, nerves and pleura. The classic anesthesia pearl is: Loss of RIGHT radial pulse during mediastinoscopy = suspect innominate artery compression READ FULL:  https://www.facebook.com/anesthesiamp4/posts/pfbid02aHUgNp59hF6NTZGqb3UdgJNYygwMzM5f3bLTwZzzLXS9fHY8SFCnveUCyPxZDkoul 🩸 1. Innominate artery compression The mediastinoscope can compress the brachiocephalic (innominate) artery, reducing blood flow to the right arm—and potentially the right carotid circulation. 👉 Monitor the right radial pulse/plethysmographic waveform continuously. Sudden loss/attenuation → tell surgeon → reposition/remove mediastinoscope. 🚨 2. Major vascular hemorrhage Potentially catastrophic injury may involve: Innominate artery → pulmonary artery → SVC/azygos system → other media...
