Everyone craned their necks like a flock of geese competing to peer through the lead glass, counting how many items were similar to those in cardiovascular interventional surgery and how many were rare and unseen.
Xie Wanying, just like Zhang Wang, seized the precious opportunity to learn diligently.
The surgeon picked up a Y-valve, connected the tubing, one end connecting to saline, preparing to inject heparin for systemic heparinization of the patient, a routine step in many interventional surgeries. Since the tube enters the femoral artery under pressure, not a venous drip, the saline bag needs pressure injection. The nurse used a pressure bag over the saline bag, inflating it with a balloon pump to replace the outdated, labor-intensive, and poorly controlled manual squeezing method.
During pressure infusion, the nurse had to keep her eyes fixed to prevent accidents.
