Postoperative pulmonary complications (PPCs), the predominant complications following lung surgery, are closely associated with intraoperative fluid therapy. This study investigates whether continuous low-dose norepinephrine infusion combined with goal-directed fluid therapy (GDFT) reduced the risk of PPCs after lung surgery relative to either GDFT alone or standard fluid treatment. ⋯ ChiCTR2200064081.

Limited literature exists on the vascular reactivity of the radial and ulnar arteries in hypertensive patients following radial artery cannulation. This study assessed the vascular reactivity of the radial and ulnar arteries by comparing Doppler images and laser speckle contrast imaging (LSCI) obtained from both normotensive and hypertensive patients after radial artery cannulation under general anesthesia. ⋯ The radial and ulnar arteries in hypertensive patients may lack a compensatory response to radial artery cannulation during general anesthesia.
