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 کاملDiffusion of nitrous oxide through endotracheal tube cuffs
Nitrous oxide (N2O) is an inhalational anesthetic that is frequently used for general anesthesia. While N2O is not sufficient for maintaining general anesthesia if used alone, when used in combination with a volatile inhalation agent, N2O decreases the minimum alveolar concentration (MAC) of the volatile inhalational agent, thereby reducing the amount of the agent required during longer procedu...
متن کاملComparison of the Laryngeal Mask Airways: Laryngeal Mask Airway-classic and Laryngeal Mask Airway-proseal in Children
Introduction In the past 25 years with the development of various supraglottic airway devices, the armamentarium for airway management has increased. In our study, the laryngeal mask airway (LMA)-ProSeal is compared with the LMA-Classic with respect to as follows: (a) Ease of insertion and number of insertion attempts, (b) Device positional stability and possible oropharyngeal leak, (c) Airway ...
متن کاملCritically injured patients, inaccessible airways, and laryngeal mask airways.
Managing the airway of a critically injured trauma patient in the prehospital environment is challenging, especially when access to the patient's airway is limited as is often the case in vehicle entrapment incidents. This paper reports the use of the laryngeal mask airway as an adjunct to airway management when attempts using simple airway management techniques have failed to provide adequate ...
متن کاملThe 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 respira...
