Scientific title
Alveolar recruitment strategy improves lung function during thoracic surgery: a prospective, randomised study
Acronym
Study hypothesis
The aim of the study is to investigate whether an alveolar recruitment strategy applied to both lungs before starting one lung ventilation (OLV) would improve gas exchange, lung mechanics and dead space
Ethics approval

Condition
Thoracic surgery
Intervention
Patients undergoing elective thoracotomy in the lateral position requiring one-lung ventilation and an arterial catheter were randomised to receive:
1. Lung recruitment manoeuvre with an inspiratory plateau pressure of 40cmH2O and PEEP of 20cmH2O was performed in this group for 10 consecutive breaths at the begining of both TLV periods
2. No lung recruitment
Intervention type
Procedure/Surgery
Phase
Not Specified
Drug names
Primary outcome measure
1. Arterial blood gases
2. Volumetric capnography
3. Ventilatory and hemodynamic data
These were recorded at the end of each one of the following study periods:
1. TLVbaseline: 5 min after placing the patient in the lateral position during TLV
2. TLV20: 20 min after placing the patient in the lateral position during TLV
3. OLV20: 20 min after OLV ventilation
4. OLV40: 40 min after OLV ventilation
5. TLVend: 10 min after re-establishing TLV once pulmonary resection was completed
Secondary outcome measures
