[Fatal complications in tracheotomized children]

Indications, complications, and surgical techniques for pediatric tracheostomies--an update

BACKGROUND

With the decrease of life-threatening obstructive upper airway infections and the ongoing improvement of intensive care medicine, the role of tracheostomy in children has been changing considerably, until now. The aim of this study was to establish data regarding indications, complications, and techniques of pediatric tracheostomy, which would reflect the current state of science.

METHODS

The authors analyzed the international literature as well as their own experience with 25 children less than 6 years of age who were operated on between 1980 and 1996.

RESULTS

Literature proved to be very heterogeneous in terms of terminology, patient groups, operation techniques, indications, and complications. Within the past decades, long-term intubation and congenital anomalies of the upper respiratory tract have become increasingly prevalent, whereas inflammatory diseases were less and less an indication for tracheostomy. Endotracheal intubation as an alternative has resulted in less frequent tracheostomies in general. Today, children can be ventilated for months without considerable complications. However, individual, clinical, and fiberoptical controls are necessary. Tracheostomy-related complications have not changed significantly. Fatalities are mostly caused by the underlying disease. The most frequent causes of tracheostomy-related death are cannula obstruction and accidental decannulation. The most frequent early complications are pneumomediastinum, pneumothorax, wound complications, and bleedings. Subsequent complications most often are granulations and tracheal stenosis.

CONCLUSIONS

The authors' research agreed widely with that in the literature. However, no tracheostomy-related death occurred. Possibly, this was because of their operative technique. In the opinion of the authors, establishing a cartilage window facilitates cannula exchange and reduces the risk of a fatal accidental decannulation.

Tracheostomy in children: there is a place for acceptable risk

BACKGROUND

Tracheostomy in children remains controversial regarding the risk of complications.

METHODS

Forty-six trauma patients (35 male and 11 female, mean age = 6.8 years) were admitted to the intensive care unit between 1987 and 1991 with severe head injury plus coma. Tracheostomy was performed with standard technique after 5.9 days (range, 2-12 days) of intubation.

RESULTS

There were no deaths from tracheostomy, but six deaths resulted from severe head injury. One child was discharged with tracheostomy. The 39 survivors remained with tracheostomy 16.14 days (range, 4-71 days) in the intensive care unit. After cannula removal, 31 remained asymptomatic; 8 had respiratory distress: 2 were normal, 5 had endoscopic treatment for subglottic granulomas/stenosis from intubation, and 1 had tracheomalacia from tracheostomy. In 1997, the 18 patients located for follow-up were asymptomatic. At endoscopy, 8 were normal, 9 had subglottal granulomas from intubation, and 1 had 20% tracheal stenosis from tracheostomy.

CONCLUSION

Most complications after tracheostomy result from intubation. Tracheostomy has an acceptable risk in children with severe head injury who need prolonged ventilatory support.
