Background :

Acute lung injury (ALI) occasionally occurs after pulmonary resection and carries a bad prognosis with a high mortality rate ranging from 20 to 100%.

Objectives :

  1. to evaluate pre-, intra- and postoperative changes in hemodynamics, oxygenation indices as well as intra- and extravascular lung water using simple thermodilution technique and continuous arterial pressure analysis
  2. to test the efficacy of inhaled beta2 -adrenergic agonist versus anticholinergic agents to reduce lung edema in patients undergoing thoracic surgery and in pigs subjected to lipolysacharide-induced ALI.

Design of the research protocol:

  • Prospective controlled trial including surgical patients with high risk factors for ALI (n=60) allocated to receive inhaled drugs (randomised, double-blind, cross-over mode).
  • Main measurements:

Intra-thoracic blood volume, intra- and extra-vascular lung water, hemodynamic parameters (CO, systolic arterial pressure/flow variations, dPmax, MAP, CVP), oxygenation indices (PaO2/FIO2), ventilatory parameters, clinical outcome data, histochemical and pathological data.

Glossary CO = cardiac output; dPmax = maximal arterial pressure slope; SAP-V = systolic arterial pressure variations; Flow–V = Flow variations; MAP = mean arterial pressure; CVP = central venous pressure; PaO2=arterial oxygen pressure; FIO2= oxygen inspiratory fraction
