Predictors of an appropriate admission to an ICU after a major pulmonary resection.

BACKGROUND: There are no recommendations about admission to an ICU after a major lung resection and there are considerable differences among institutions in this respect. OBJECTIVES: To audit the practice of admission to an ICU after a major lung resection and evaluate factors predicting the need for intensive care. METHODS: Clinicalrecords of all patients who underwent major pulmonary resections in a 14-month period were reviewed retrospectively. The criteria for postoperative admission to the ICU were: (1) standard pneumonectomy if comorbidity index (CI) >0 and/or ASA score >1, and/or abnormal spirometry or arterial gas analysis; (2) extended pneumonectomy; (3) lobectomy if CI >or=4 and/or ASA >or=3; (4) lobectomy if FEV(1) <60% of predicted; (5) lobectomy if FEV(1) is between 60 and 80% and hypercapnia. RESULTS: Among the 49 patients postoperatively admitted to the surgical ward, only 1 needed late intensive care. Among the 55 patients admitted to the ICU, 25 did not require specific intensive care and were discharged 24 h postoperatively, whereas the remaining 30 patients required specific intensive care. Multivariate analysis identified ASA score, predictive postoperative DL(CO), and predictive postoperative product (PPP) as independent predictors of a need for admission to an ICU. CONCLUSION: This empirical protocol was useful in identifying patients not likely to need admission to the ICU. ASA score, predictive postoperative DL(CO), and PPP are independent predictors of a need for admission to an ICU.

Idiopathic bronchiolitis mimicking diffuse panbronchiolitis.

Diffuse panbronchiolitis (DPB) is a distinct sinobronchial syndrome which has been almost exclusively reported in East Asia; only a few cases have been observed in non-Asians so far. Since 1990, when one of us described the first European case, we have screened all patients presenting with a clinical, physiopathological and radiological pattern compatible with DPB, in order to assess if the paucity of proven cases in Europe could reflect a lack of awareness of this disease among both pulmonologists and pathologists. Over a 10-years period we identified four additional DPBs, but also interestingly observed five cases of "idiopathic" bronchiolitis (IB) that had both clinical symptoms and high-resolution computed tomography (HRCT) findings indistinguishable from those of DPB, but did not show the typical histological changes. All these patients were Caucasians and presented with dyspnea, productive cough, an obstructive or mixed impairment on pulmonary function tests and chest HRCT features strongly suggesting a grade II to IV DPB. We suggest that diseases classified as IB in this study might be homogeneous entities which are clinically and radiologically similar to DPB.

Role of fiberscopic transbronchial needle aspiration in the staging of N2 disease due to non-small cell lung cancer.

BACKGROUND: Transbronchoscopic needle aspiration (TBNA) can offer a unique opportunity to identify surgically unresectable lung cancer and to avoid surgical mediastinal exploration in many patients with mediastinal lymph node extension of the tumor. The aim of this study was to assess the yield of TBNA performed with either histology or cytology needles in mediastinal staging of N2 disease due to non-small cell lung cancer (NSCLC). METHODS: Retrospective chart review was carried out on 194 TBNA procedures performed between January 1997 and September 2000 at a single institution. Inclusion criteria were pathologic evidence of NSCLC; contrast enhancement computed tomography scan of the chest suggesting N2 disease; and negative bronchoscopic examination for possible neoplastic lesions at the site of RESULTS: Overall sensitivity and diagnostic accuracy were 71% and 73%, respectively, with no significant differences between 19-gauge and 22-gauge cytology needles. Procedures performed for right paratracheal and subcarinal lymph node stations had a significantly higher yield than those for the left paratracheal station. CONCLUSIONS: TBNA mediastinal staging, performed during the initial diagnostic evaluation of NSCLC, can spare costs and risks of more invasive procedures in patients with inoperable tumors, in patients who are not candidates for operation because of coexistent significant comorbidities, and in patients with N2 disease.
