Percutaneous endoscopic tracheostomy

Traqueostomía percutánea con asistencia fibrobroncoscópica: Evaluación prospectiva de 100 casos consecutivos y revisión de la literatura

“…Hacia finales de la década 1980-89, la incorporación de la fibrobroncoscopia para guiar el procedimiento y adicionar mayor seguridad a la TPC fue sugerida por varios autores [41][42][43][44] . Barba y cols 45 , encontraron una menor incidencia de complicaciones en el grupo de pacientes sometidos a TPC con asistencia…”

Percutaneous dilatational tracheotomy

“…When surgeons became familiar with the technique these factors became less of a contraindication and percutaneous dilatational tracheotomy became the preferred method of tracheotomy in patients with difficult anatomy at many institutions [65,67]. In these patients endoscopy and ultrasound may be helpful to puncture the tracheal lumen and to avoid guidewire dislodgement and false passage [68,69].…”

“…Endoscopy is helpful to avoid incorrect placement of the needle, dilatation outside the tracheal lumen and malplacement of the cannula [68,69]. However, it is claimed that it makes ventilation more difficult because of flow limitation through the translaryngeal tube by the presence of the fibreoptic scope [98,-104,116].…”

“…Endoscopic assistance can be used to verify correct placement of the needle into the tracheal lumen, guide wire insertion, dilatation and cannulation during the procedure [68,69].…”

“…?' • Tracheobronchoscopy may be helpful to check the position of the cannula and to evacuate bloodclots which may occlude one of the bronchi and may be also responsible for high ventilatory pressures [68,69,104].…”
