Reflux during positive pressure ventilation via the laryngeal mask airway?
Sir,—We read with interest the pilot study by Valentine, Stakes and Bellamy [1] comparing lower oesophageal pH changes in patients managed with either the laryngeal mask airway (LMA) or tracheal tube during intermittent positive pressure ventilation (IPPV). However, we suggest that the following factors in their study design may have had an influence on their results. (1) The authors probably u...
متن کاملPositive pressure ventilation during fibreoptic intubation: comparison of the laryngeal mask airway, intubating laryngeal mask and endoscopy mask techniques.
BACKGROUND The efficacy of delivery of mechanical ventilation through different airway devices during fibreoptic intubation is not known. METHODS We compared the laryngeal mask airway (LMA), intubating laryngeal mask (ILM) and endoscopy mask for positive pressure ventilation (PPV) during fibreoptic intubation. In 80 adult paralysed patients, fibreoptic intubation was performed during PPV usin...
متن کاملProSeal versus the Classic laryngeal mask airway for positive pressure ventilation during laparoscopic cholecystectomy.
BACKGROUND We tested the hypothesis that the ProSeal laryngeal mask airway (PLMA) is a more effective ventilatory device than the Classic laryngeal mask airway (LMA) for laparoscopic cholecystectomy. METHODS Eighty anaesthetized, paralyzed patients (ASA 1-2, aged 18-80 yr) were randomly allocated for airway management with the PLMA or LMA. Ease of insertion and efficacy of seal were determine...
متن کاملThe use of the laryngeal mask airway with mechanical positive pressure ventilation.
The purpose of this article is to discuss the benefits, safety, and efficacy of the laryngeal mask airway (LMA) and identify the risks and misconceptions associated with LMAs when used with positive pressure ventilation (PPV). Despite the abundance of supporting evidence that LMAs may be used successfully in a variety of age groups and surgical procedures using PPV, many anesthesia providers ar...
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 ...
