Cricothyroidotomy for long-term tracheal access. A prospective analysis of morbidity and mortality in 76 patients

Cricothyroidotomy for long-term tracheal access was prospectively studied in 76 critically ill patients. Thirty patients (39%) survived and 46 (61%) died. Mean duration of follow-up computed in all survivors was 8.5 months. Postmortem examination of the airway was performed in 85% of the nonsurvivors. Five patients (7%) had major complications including one death, subglottic stenosis in two adolescent patients, reversible subglottic granulation with partial obstruction in one patient, and tracheomalacia in one patient. Minor complications occurred in 23 (30%) survivors. Eleven (28%) of the nonsurvivors examined post mortem had airway pathology, including ulceration, hemorrhage and abscess at the stoma or cuff site, subglottic erosion, and mucosal separation. There were no significant differences in any of the parameters studied between the group with and the group without airway pathology. The morbidity and mortality of cricothyroidotomy in adults are similar to that reported for tracheostomy. However, cricothyroidotomy should be avoided in children and adolescents because of the risk of subglottic stenosis.
