Complications Related to the Anaesthesia During Airway Endoscopy in Children With Tracheostomy.

The goal of this observational study is to investigate the incidence of severe anaesthesiologic complications during anaesthesia in children with tracheostomy undergoing surveillance airway endoscopy. The main question it aims to answer is how common severe anaesteshiologic complications are in these patients and investigate if there is an association between severe anaesthesiologic complications and patient related factors. Primary outcome: The incidence of severe anaesthesiologic complications in children with tracheostomy undergoing surveillance airway endoscopy. Secondary outcome: The association between severe anaesthesiologic complications and patient related factors: age at tracheostomy, age at surveillance endoscopy, ventilator dependence, current and previously diagnosed tracheostomy related airway complications. All children under 18 yrs. of age with a tracheostomy accepted for general anaesthesia undergoing surveillance airway endoscopy at the Long term Intensive Care unit at Karolinska University Hospital Stockholm Sweden will be eligable for inclusion. The anaesthesia will be conducted according to current practise and complications will recorded by the anaesthesiologist in charge. Participants may only be included several times during the study period.
