OXYGEN THERAPY AFTER THORACOTOMY

G. B. Drummond, A. C. Milne
1978 Survey of Anesthesiology  
Arterial blood samples were taken from patients before thoracotomy, and on the 1st day after operation, with the patient breathing first air, and then 24%, 28% and 35% oxygen from a venturitype mask. Pao t was reduced markedly by operation, the reduction being related to the value before operation. Oxygen therapy restored P&o t to a value greater than the value before operation in nine of 11 patients and was not associated with significant increases in Paco,. The effect of administration of
