In the period 1984 to 1988, 2,448 patients underwent major thoracic
operations in our unit. Of these patients, 144 (5.9%) underwent
percutaneous cricothyroidostomy (minitracheostomy) using a 20F pediatric
silver tracheostomy tube. Minitracheostomies were performed for the
treatment of sputum retention in 81 patients, prophylactically in 62
patients, and as a route for high-frequency jet ventilation in 1 patient.
Minitracheostomy tubes remained in situ a median of four days. Suction
function was satisfactory in 99% of patients, with only 2 patients
requiring subsequent suction bronchoscopy and no occurrence of tube
blockage. Ninety-four percent of minitracheostomies performed were entirely
uneventful. Bleeding was the most common complication (3.5%), and no
instances of subglottic stenosis have occurred. During the review period,
there was a significant increase in the percentage of patients requiring
major operations undergoing prophylactic, but not therapeutic,
minitracheostomy (p less than 0.001). This was associated with a
significant decrease in the percentage of patients requiring suction
bronchoscopy (p less than 0.001). We conclude that prophylactic
minitracheostomy with the 20F pediatric silver tracheostomy tube is a safe
and effective procedure in the prevention of postoperative sputum
retention.
