Randomized Controlled Trial
The effects of thoracic epidural blockade on ventilation-perfusion matching during one-lung ventilation: An exploratory study.
Electrical impedance tomography (EIT) enables continuous image acquisition, facilitating real-time measurements of ventilation and perfusion at the clinical bedside. Experimental and clinical studies on controversial effects of thoracic epidural blockade (TEB) with local anesthetics on ventilation-perfusion(V/Q) matching and hypoxia during one lung ventilation (OLV) are rare. The aim of this study was to use EIT to investigate the effects of TEB combined with general anesthesia on pulmonary perfusion distribution and V/Q matching during one-lung ventilation. ⋯ Based on the contrast-enhanced EIT evaluation of pulmonary perfusion and ventilation, TEB appears to induce a V/Q mismatch in patients undergoing OLV in the lateral position for thoracic surgery.

Randomized Controlled Trial
Effect of inspiratory oxygen fraction during driving pressure-guided ventilation strategy on pulmonary complications following open abdominal surgery: A randomized controlled trial.
The aim of the present study was to determine the effect of 30 % fraction of inspired oxygen (FIO2) compared with 80 % FIO2 in the context of driving pressure-guided ventilation strategy on pulmonary complications following open abdominal surgery. ⋯ In patients undergoing open abdominal surgery, using a 30 % FIO2, compared with 80 % FIO2, in context of driving pressure-guided ventilation strategy, intraoperatively reduced the incidence and severity of pulmonary complications within the first 7 postoperative days.

Randomized Controlled Trial
Effect of low-dose norepinephrine combined with goal-directed fluid therapy on postoperative pulmonary complications in lung surgery: A prospective randomized controlled trial.
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.

Randomized Controlled Trial Comparative Study
Efficacy and safety of remimazolam versus dexmedetomidine for patients undergoing flexible fiberoptic bronchoscopy: A randomized, clinical trial.
Remimazolam's benefits for patients undergoing painless flexible fiberoptic bronchoscopy remain uncertain. We aimed to compare the efficacy and safety of remimazolam and dexmedetomidine in flexible fiberoptic bronchoscopy (FFB). ⋯ Remimazolam is effective and safe in painless flexible fiberoptic bronchoscopy. It allows a lower procedure interruption rate and incidence of oxygen desaturation, providing better hemodynamic stability compared to dexmedetomidine.

Randomized Controlled Trial Comparative Study
Effects of neuromuscular block reversal with neostigmine/glycopyrrolate versus sugammadex on bowel motility recovery after laparoscopic colorectal surgery: A randomized controlled trial.
To compare the effects of neostigmine/glycopyrrolate (a traditional agent) and sugammadex on bowel motility recovery and the occurrence of digestive system complications after colorectal surgery. ⋯ The time to the first flatus was shorter using 2 mg.kg-1 sugammadex to reverse the neuromuscular block for laparoscopic colorectal surgery compared to reversal with conventional neostigmine/glycopyrrolate.
