title: A clinical study of the value of a mixture of nitrous oxide and oxygen as an analgesic in relief of pain following thoracic surgery and its usage physiotherapeutically.
abstract: When patients have been subjected to thoracic and abdominal surgery, the ability to cough and ventilate the lungs adequately is inhibited post-operatively by pain and apprehension. The use of anaesthetic agents to relieve pain on stretching the incision has been investigated previously, particularly with patients following abdominal surgery.
