Dermatologic complication following axillary cannulation for aortic dissection repair

Abstract

Key Clinical Message It is important to be aware of complications associated with axillary artery cannulation, especially the more common ones that can compromise limb integrity. Pulse oximeter and arterial line placed on the right upper extremity can aid in perfusion of the right arm during right axillary artery cannulation.

A Novel Photoplethysmography Sensor for Vital Signs Monitoring from the Human Trachea

“…Pulse oximetry is perhaps the most important development in patient monitoring in the last forty years, however its limitations are well known and well documented [1][2][3][4]. Despite improvements in the accuracy of pulse oximetry brought about by advances in signal processing over the last decade or so [5], reliable and dependable SpO 2 readings still depend on adequate periphery perfusion, especially in anaesthetised patients While seldom reported in literature these instances do happen [6]. There is a recognised need for improved pulse oximetry performance in some groups of vulnerable patients, especially as current coping methods only compromise patient safety and place an unwanted burden on the surgical team as they try to restore monitoring.…”
