Core Tip

Core tip: The placement of laryngeal mask airway (LMA) may affect the position and blood flow of the internal jugular vein (IJV). The results of our study show that the placement of Supreme, Guardian, and I-gel LMA can increase the overlap index, reduce the success rate of IJV puncture, increase the incidence of arterial puncture, and cause congestion of IJV. Type of LMA did not influence the difficulty of IJV puncture. Therefore when LMA is used, ultrasound is recommended to guide the IJV puncture.
