Airway morphological abnormalities of bronchiolitis assessed by endobronchial optical coherence tomography.

Background: A few studies have reported the medium-sized and small airway morphological abnormalities of bronchiolitis. Whether spirometry or impulse oscillometry (IOS) is correlated with airway remodeling of bronchiolitis remains unclear.

Objectives: Aiming to demonstrate the airway morphological abnormalities of bronchiolitis obliterans (BO) and diffuse panbronchiolitis (DPB) assessed by endobronchial optical coherence tomography (EB-OCT), and elucidate whether spirometric and IOS parameters have correlation with the airway remodeling of bronchiolitis.

[Clinical Application of Preoperative Autologous Blood Donation in Selective General Surgery].

Objective: To study the clinical effects of preoperative autologous blood donation (PABD) in selective general surgery.

Methods: Paired study was performed in PABD group with 70 PABD cases screened from selective general surgery during the period from November 2017 to August 2018 in our hospital, and the control group included 70 cases without preoperative autologous blood donation, the baseline data before surgery were not significantly different. The transfusion quantities of allogeneic RBC and plasma, the levels of perioperative hemoglobin and platelets, the time and expense of hospitalization were compared between two groups.

Postintubation Tracheal Stenosis Evaluated by Endobronchial Optical Coherence Tomography: A Canine Model Study.

Background: The predictors and airway morphological changes during the development of postintubation tracheal stenosis (PITS) have not been well elucidated.

Objectives: To elucidate the validation of endobronchial optical coherence tomography (EB-OCT) in assessing the airway morphological changes in PITS.

Methods: We performed oral endotracheal intubation in 12 beagles to establish the PITS model.

Evaluation of the Normal Airway Morphology Using Optical Coherence Tomography.

Background: The anatomic location of small airways, the distribution of airway cartilage, and their correlation with ageing have not been well elucidated. The objective of this article was to explore the morphologic characteristics of small airways in vivo, and how airway structural changes correlate with age using endobronchial optical coherence tomography (EB-OCT).

Methods: We recruited 112 subjects with peripheral pulmonary nodules.
