Randomized Controlled Trial
Individual FiO2 guided by SPO2 prevents hyperoxia and reduces postoperative atelectasis in colorectal surgery: A randomized controlled trial.
To determine whether individualized fraction of inspired oxygen (iFiO2) improves pulmonary atelectasis after elective laparoscopic colorectal surgery relative to 60 % FiO2. ⋯ ChiCTRT2100049615.

Multicenter Study
Intraoperative FiO2 and risk of impaired postoperative oxygenation in lung resection: A propensity score-weighted analysis.
To assess whether, in a lung resection cohort with a low probability of confounding by indication, higher FiO2 is associated with an increased risk of impaired postoperative oxygenation - a clinical manifestation of lung injury/dysfunction. ⋯ Despite plausible harm from hyperoxia, high intraoperative FiO2 is extremely common during lung resection. Nearly three-quarters of lung resection patients with acceptable oxygenation received median intraoperative FiO2 ≥ 0.8. Such higher FiO2 was associated with an increased risk of impaired postoperative oxygenation - a clinically relevant manifestation of lung injury or dysfunction. This observation supports the administration of a lower (< 0.8) intraoperative FiO2 and its further assessment in clinical trials.

Randomized Controlled Trial Observational Study
Ultrasound-assisted middle thoracic epidural catheter placement utilizing the most dorsal sites of bilateral transverse process roots as anatomical landmarks: A cadaveric observational study and a clinical randomized controlled trial.
We developed an innovative method for ultrasound-assisted thoracic epidural catheter placement and assessed its potential to reduce procedural duration for trainees. ⋯ Our novel technique for thoracic epidural catheter placement resulted in expedited needling and enhanced success rates among trainees, although there was no significant difference between total procedure time when using ultrasound guidance and that when using conventional palpation.
