- Thoracic Anaesthesia
- Indications for OLV
- Protection of healthy lung
- Infection
- Lung lavage
- Massive haemorrhage
- Preventing ventilation to one lung
- Bronchopleural fistula
- Risk of rupture eg large bulla
- Surgical procedures
- VAT
- Surgery to proximal bronchial tree
- Improve surgical access
- Pneumonectomy
- Lobectomy
- Oesophagectomy
- Spinal surgery
- Lung carcinoma resection
- 3 conditions need to be met:
1. Non-small cell
2. Surgically resectable
3. Patient wants surgery
- High risk
pCO₂ >6kPa
SpO₂ <90%
Desaturation >4% with exercise - FEV1 of >1.5L for Lobectomy
FEV1 of >2L for pneumonectomy - Predicted post-op values
Lobectomy: bronchopulmonary segments to left out of of total number (19) x pre-op FEV1.
Quantitative V/Q scanning using technetium labelled macroaggregates gives more accurate results.
Aim for PPO-FEV1 of 0.7-0.8L
- CPEX testing
- Patients with major CV risk factors need cardiology opinion
- Within 6 months of MI
USA
CCF
High degree AV block
Symptommatic arrhythmias
Severe valvular disease
- Routine PFTs
- FEV1 >1.5L suitable for Lobectomy
FEV1 >2L suitable for pneumonectomy - FEV1 <1.5L (Lobectomy)
FEV1 <2L (pneumonectomy) - Quantitative lung scan
- % ppo FEV1 >40%
% ppo TLCO >40% - % ppo FEV1 <40%
% ppo TLCO <40% - Exercise testing
- VO₂ max >15ml/kg/min
- VO₂ max <15ml/kg/min
