A model to predict the decline of the forced expiratory volume in one second and the carbon monoxide lung diffusion capacity early after major lung resection.
The objective of the study was to develop regression models for the prediction of the decline of the forced expiratory volume in one second (FEV1) and the carbon monoxide lung diffusion capacity (DLCO) early after major lung resection. One hundred and ninety patients submitted to pulmonary lobectomy or pneumonectomy for lung cancer performed preoperative and early postoperative (mean 10.9 after operation) pulmonary function tests. One hundred and fifty of these patients also underwent DLCO measurements by the single breath method. ⋯ The following regression equations were derived: estimated percent reduction in FEV1 = 21.34 - (0.47 x age) + (0.49 x percentage of functioning parenchyma removed during operation) + (17.91 x COPD-index); estimated percent reduction in DLCO = 35.99 - (0.31 x age) - (36.47 x FEV1/FVC ratio) + (0.33 x DLCO) + (0.54 x percentage of functioning parenchyma removed during operation). The comparison between observed and estimated losses of FEV1 and DLCO (by using these regression equations) was not significantly different. We think the regression models generated in this study may be reliably used for risk stratification purposes.

An introductory educational module for cardiothoracic trainees.
In an attempt to enhance training we have developed an innovative introductory educational module for cardiothoracic trainees. Newly appointed cardiothoracic trainees at the Yorkshire Heart Centre in Leeds have piloted a 6-month programme, comprising 3 months attachment to the Cardiothoracic Intensive Care Unit, and 3 months seconded to allied departments. This report describes this programme, and considers its advantages and disadvantages.
