Randomized Controlled Trial
Postoperative Oxygen Therapy in Patients with Obstructive Sleep Apnea: A Randomized Controlled Trial.
Surgical patients with OSA are at increased risk for perioperative complications. Postoperative supplemental oxygen is commonly used, but it may contribute to respiratory depression in patients with OSA receiving opioids. The objective of the study is to investigate the effect of postoperative supplemental oxygen on arterial oxygen saturation (Sao2), sleep respiratory events, and CO2 level in patients with untreated OSA. ⋯ Postoperative supplemental oxygen was found to improve oxygenation and decrease the AHI without increasing the duration of apnea-hypopnea event or PtcCO2 level. A small number of patients had significant CO2 retention while receiving supplemental oxygen.

Stylet Usage Does Not Improve Diagnostic Outcomes in Endobronchial Ultrasound Transbronchial Needle Aspiration: A Randomized Clinical Trial.
Endobronchial ultrasonographically guided transbronchial needle aspiration (EBUS-TBNA) of thoracic structures is a commonly performed tissue sampling technique. The use of an inner-stylet in the EBUS needle has never been rigorously evaluated and may be unnecessary. ⋯ Omitting stylet use during EBUS-TBNA does not affect diagnostic outcomes and reduces procedural complexity.
