Influence of cuff volume on oropharyngeal leak pressure and fibreoptic position with the laryngeal mask airway.
We studied the size 4 laryngeal mask airway (LMA) to test the hypothesis that oropharyngeal leak pressure and fibreoptic position improves with increasing cuff volume. After LMA insertion, 50 anaesthetized adult patients had the cuff inflated in 5-ml increments to 40 ml. Oropharyngeal leak pressure was optimal at 15 ml and decreased at higher volumes. The fibreoptic position was optimal at 0-20...
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 کاملPressure controlled versus volume controlled ventilation with laryngeal mask airway.
STUDY OBJECTIVE To quantify the impact on peak airway pressure of pressure-controlled and volume-controlled ventilation during Laryngeal Mask Airway (LMA) use. DESIGN Prospective, crossover clinical study. SETTING University-affiliated hospital. PATIENTS 32 ASA physical status I and II patients undergoing general anesthesia with the LMA. INTERVENTIONS Patients were ventilated for three ...
متن کاملEmergency airway management with laryngeal mask airway.
When used correctly, laryngeal mask airway is a life saver. We report two cases wherein it was used for rescue airway management and as a ventilatory device during anesthesia. It is concluded that an anesthetist should be familiar with the use of this device.
متن کاملThe 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...
