Long-term Flap Tracheostomy in a Pediatric Animal Model

A single-center 6-year experience with two types of pediatric tracheostomy

“…Vertical tracheal incision [17][18][19] and creation of inferiorly [17,18,20] or superiorly [19] based tracheal flaps in animal models have also been studied. The incidence of late complications related to the stoma or tracheal lesions such as tracheal stenosis, formation of granulation tissue, suprastomal collapse, or fatal complications could not clearly be related to the type of tracheal incision or the creation of a tracheal flap [21,22].…”

Microsurgical tracheotomy: A pediatric model in growing rats

“…2,11-14 However, among experimental studies with tracheotomy incisions, just few articles were published using growing animals, 2,11,12 in an attempt to develop a pediatric model.…”

“…This shows that the operative procedure and the presence of the tracheotomy cannula, which could have caused some discomfort in the animal, did not prevent appropriate food intake. In studies by Mendez-Picon et al 11 and Miller et al 2 no weight measurements were made after cannula removal. That is the reason we cannot have the data compared.…”

“…AND NEIL FERREIRA NOVO, M.D., Ph.D. 2 Previous studies described controversial opinions about pediatric tracheotomy concerning type of tracheal incision and long-term results, which remain as important research subjects. Experimental studies on rat tracheas are scarce, probably because of technical difficulties related to the structures' small dimensions.…”

“…1 It is performed to manage upper airway obstructions in children and adults, in prolonged mechanical ventilation and pulmonary toilet. 2 Caron, a French surgeon from Saint Germain en Laye, made the first successful tracheotomy in a child in 1776; the patient was a 7-year-old boy, and the procedure removed an aspirated bean. 3 Pediatric tracheotomies have been associated with significant morbidity and mortality, when compared to those in adults.…”
