The effect of nitrous oxide on laryngeal mask cuff pressure.
During general anesthesia with the laryngeal mask airway (LMA), a significant increase in cuff pressure due to diffusion of nitrous oxide through the cuff wall occurs. This descriptive clinical study was conducted in a university teaching hospital ambulatory surgical center with 100 patients (ASA physical status, I-III; age, 5 months to 76 years; weight, 5.8-146.3 kg) undergoing general anesthe...
متن کاملLaryngeal mask airway performance: effect of cuff deflation during anaesthesia.
We studied the effect of deflating the laryngeal mask airway (LMA) cuff in situ on recorded respiratory tidal ventilation in 30 spontaneously breathing anaesthetized patients. Another 26 patients were studied in whom the LMA cuff was undisturbed. Deflation of the cuff to a pressure of 22 mm Hg (below an estimated arteriolar perfusion pressure of the pharyngeal mucosa), by removing approximately...
متن کامل[Impact of the practising anesthesiologist team member on the laryngeal mask cuff pressures and adverse event rate].
OBJECTIVE We have planned to evaluate the laryngeal mask cuff pressures (LMcp) inflated by anesthesia workers of several seniority, without using manometer. METHODS 180 patients scheduled to have short duration surgery with laryngeal mask were included in the study. Five anesthesia specialists (Group S), 10 residents (Group R) and 6 technicians (Group T) inflated the LMc; thereafter LMcp were...
متن کاملEndotracheal tube and laryngeal mask airway cuff pressures can exceed critical values during ascent to higher altitude.
OBJECTIVES Tracheal mucosal perfusion is compromised at an endotracheal tube (ETT) cuff pressure of 30 cm H(2)O, and blood flow is obstructed at a pressure of 50 cm H(2)O. METHODS We measured the change in pressure of air-filled cuffs of 6.0 and 7.5 ETTs and a size 4 laryngeal mask airway (LMA) from sea level to 2400 m. The ETTs and LMA cuff measurements were done with the devices uncontained...
متن کاملEndobronchial cuff pressures.
In 20 adult patients (18 male) who presented for thoracotomy, the trachea was intubated using Mallinckrodt disposable double-lumen tubes (18 large and two medium). The endobronchial cuff was inflated by a trained operating department assistant using an air-filled syringe. The volume of air and the initial endobronchial cuff pressure were measured. The minimum cuff pressure required to prevent r...
