Dynamic variation of the axillary veins due to intrathoracic pressure changes: A prospective sonographic study.

CONCLUSIONS: Anatomical variations in depth and diameter as well as the collapsibility due to intrathoracic pressures changes represent common challenges that face clinicians during central venous catheterization of the axillary vein. A noteworthy increase in vessel size as patients transition from spontaneous to mechanical ventilation may theoretically improve first-pass cannulation success with practitioners skilled in both ultrasound and procedure. As a result, placing a centrally inserted central catheter after the induction of anesthesia may be beneficial. PMID: 31204560 [PubMed - as supplied by publisher]
