title: [Laryngeal mask vs tracheal tube in pediatric anesthesia in the presence of upper respiratory tract infection].
abstract: BACKGROUND
  The aim of this report is to assess the incidence of postoperative respiratory complications in patients recently suffering from inflammation of the upper respiratory tract in whom a LMA or an uncuffed orotracheal tube have been used.
  
  
  METHODS
  Four hundred patients were enrolled aged 6 months to 12 years undergoing general anaesthesia for elective body surface surgery with insertion of the LMA (group M) or the uncuffed tube (group T). Acute inflammation of the upper airways (URI) was assessed, defined by the presence of at least two of the following symptoms, rhinorrhea, coughing, pharyngodynia, disphony, fever, malaise. The appearance of post-surgical adverse respiratory events (ARE), such as laryngospasm, stridor, disphony, excessive coughing was detected. Patients were divided into four groups in relation to the management of the airway and the presence or otherwise of URI (M URI, M NO URI, T URI, T NO URI).
  
  
  RESULTS
  In NO URI patients, the presence of ARE was 9.6% in the M and 36.9% in the T group (p < 0.001); in URI patients, these figures were respectively 31.5% and 73.9% (p < 0.001).
  
  
  CONCLUSIONS
  The frequency of ARE increases significantly in URI patients with both LMA and the tracheal tube, but with the former is far lower than with the latter. Despite the appearance of only minor and transient complications, it is confirmed that the tracheal intubation is an additional risk factor as a result of the mechanical airway simulation. In recent URI, it would seem appropriate to avoid tracheal intubation, if possible, preferring the LMA.
