Prediction of Postoperative Complications: Ventilatory Efficiency and Rest End-tidal Carbon Dioxide.

Background: Cardiopulmonary exercise testing parameters including ventilatory efficiency (V/VCO slope) are used for risk assessment of lung resection candidates. However, many patients are unable or unwilling to undergo exercise. V/VCO slope is closely related to the partial pressure of end-tidal carbon dioxide (PCO).

Poor ventilatory efficiency during exercise may predict prolonged air leak after pulmonary lobectomy.

Unlabelled: Poor ventilatory efficiency, defined as the increase in minute ventilation relative to carbon dioxide production during exercise (VE/VCO2 slope), may be associated with dynamic hyperinflation and thereby promote the development of prolonged air leak (PAL) after lung resection. Consecutive lung lobectomy candidates (n = 96) were recruited for this prospective two-centre study. All subjects underwent pulmonary function tests and cardiopulmonary exercise testing prior to surgery.

Transbronchial biopsy from the upper pulmonary lobes is associated with increased risk of pneumothorax - a retrospective study.

Background: Pneumothorax (PTX) is one of the most common complications of transbronchial biopsy (TBB). Previous research suggests that upper pulmonary lobe TBB may be associated with increased risk of PTX development. The aim of this study was to compare the risk of PTX after TBB performed from different pulmonary lobes.
