Case ReportsSwallowing disorders in patients with prolonged orotracheal intubation or tracheostomy tubes.
Eleven patients were tested for swallowing dysfunction after prolonged orotracheal intubation. Ten had a tracheostomy tube. Mean duration of orotracheal intubation was 19.9 days, mean age 65 yr, and no patient had a concomitant neurologic deficit. ⋯ We concluded that prolonged orotracheal intubation with or without tracheostomy may cause prolonged and severe swallowing dysfunction. The deficits improve with time. The presence of a gag reflex does not confer protection against aspiration of pharyngeal contrast.

Emergency tracheal intubation in the postanesthesia care unit: physician error or patient disease?
Inadequate airway maintenance has been a major factor in perioperative morbidity. To determine the incidence and etiology of emergency tracheal intubations in the postanesthesia care unit (PACU), we retrospectively reviewed 13,593 consecutive admissions to our PACU from October 1986 through October 1988. Twenty-six patients (26/13,593 = 0.19%) required the insertion of an endotracheal tube while in the PACU. ⋯ There was no association between intubation and gender (P = 0.74), anesthetic technique (P = 0.41), or anesthetic agent (P = 0.49). Of the 26 intubations, 18 (69%) were considered to be directly related to anesthetic management. Despite the extremely low incidence of emergency tracheal intubation in a heterogeneous group of patients admitted to our PACU, preventable anesthesia-related etiologic factors including excessive sedative or anesthetic effect, inappropriate fluid management, persistent muscle relaxant effect, and upper airway obstruction contributed to the majority of these intubations.

The effects of ventilator rate and inspired humidity on the large airway epithelium of newborn lambs have been studied using scanning electron microscopy. Significant deciliation, denudation and necrosis occurred at both high and conventional rates if the inspired gas had low humidity. The damage observed was mild in the high humidity groups.
