In cases of severe scoliosis, some degree of respiratory disability may be present. If operative correction of the deformity is proposed, accurate assessment is required preoperatively and careful attention should be given to ventilation during anaesthesia and in the postoperative period. Measurements of ventilation have been taken pre- and post-operatively and an analysis of the results will be the subject of a future publication.
Blood loss may be severe during the operation of spinal fusion combined with Harrington rod instrumentation and adequate blood transfusion is essential. Methods to reduce blood loss are discussed.
An anaesthetic method is suggested which includes moderate hyperventilation combined with a negative phase in expiration. Local infiltration of the operative site with a vasoconstrictor is recommended. Meticulous attention should be given to the positioning of the patient and undue pressure on the anterior abdominal wall avoided.
