Uso da máscara laríngea descartável em adenotonsilectomias

Abstract

Summary: Ranieri Jr D, Neubauer AG, Ranieri DM, Nascimento Jr P -The Use of Disposable Laryngeal Mask Airway for Adenotonsillectomies. Background and objectives:Tracheal intubation associated with airway operations can cause complications such as laryngospasm, bronchospasm and periods of reduced oxygen saturation. Such complications are frequently reported during adenotonsillectomies, a procedure that by nature increases the incidence of airway complications. The objective of this study was to compare the occurrence of respiratory problems during adenotonsillectomies while using either a disposable laryngeal mask airway (LMA) or an endotracheal tube (TT).

Complicaciones del uso de la Máscara Laríngea en Pacientes Pediátricos. Estudio Multicéntrico

“…The percentage of respiratory complications according to Nascimento et al was described as 43% in children. This percentage is higher compared to ours because in lactating children the epiglottis folds over the mask thus occluding the larynx, and a risk of movement and displacement of the supraglottic device also exists; thus, the risk increases [6].…”

“…In agreement with the percentage of laryngospasm in our study and being one of the most feared respiratory complications due to severe hypoxemia that requires immediate treatment, this study presented the lowest incidence of complications, and no need to add another anesthetic technique existed. Thus, the mask has universal use in out-patient procedures and complex upper airway surgeries [6].…”

“…Ranieri suggested that the laryngeal mask protects the airways, a fact that could be confirmed by fibroscopy; however, it is not without complications: (1) bronchospasm (4.9%), ( 2) laryngospasm (0.9%), (3) stridor (1.9%), ( 4) hoarseness (9.6%), and (5) regurgitatio n (0.9%) [6].…”
