A flexible laryngeal mask airway device (LMAD) embedded with 2 pharyngeal suction catheters was used for a young female patient who underwent a revision rhinoplasty, septoplasty, and chin implant. The modified LMAD was constructed by attaching 2 suction catheters onto the back of the mask; it functioned well without signs of malfunction or complications, with a total of 71 mL of blood evacuated from the pharyngeal area during the five and a half hour surgery. The patient emerged from anesthesia without coughing or straining, and reported no sore throat or nausea/vomiting in the recovery room...

BACKGROUND: International neonatal resuscitation guidelines recommend the use of laryngeal mask airway (LMA) with newborn infants (≥34 weeks' gestation or >2 kg weight) when bag-mask ventilation (BMV) or tracheal intubation is unsuccessful. Previous publications do not allow broad LMA device comparison. OBJECTIVE: To compare delivered ventilation of seven brands of size 1 LMA devices with two brands of face mask using self-inflating bag (SIB). DESIGN: 40 experienced neonatal staff provided inflation cycles using SIB with positive end expiratory pressure (PEEP) (5 cmH2O) to a specialised newborn/infant training manikin randomised for each LMA and face mask...

After sedation with midazolam, induction of anesthesia with propofol was attempted in a patient taking modafinil. However, even after administration of a total of 6 mg/kg propofol IV, the patient continued to respond to tactile stimulation. Concurrently, the bispectral index was 72. Subsequent administration of low concentration sevoflurane by facemask induced an anesthetic depth that allowed unproblematic insertion of a laryngeal mask airway. Anesthesia for ophthalmologic surgery was maintained with sevoflurane...

The complication rate and efficacy of the Cobra Perilaryngeal Airway (CobraPLA) and laryngeal mask airways (LMAs®) have been evaluated in the published literature, but the conclusions have been inconsistent. The aim of this systematic review and meta-analysis was thus to assess the performance of the CobraPLA and LMAs under general anesthesia. We searched PubMed, Embase, and the Cochrane Library for randomized controlled trials comparing the CobraPLA with LMAs under general anesthesia. The LMAs used for comparison were the classic LMA (CLMA) and the unique LMA (ULMA)...

We conducted both conventional pairwise and Bayesian network meta-analyses to compare the clinical properties of supraglottic airway devices in children. We searched six databases for randomised clinical trials. Our primary end-points were oropharyngeal leak pressure, risk of insertion failure at first attempt, and blood staining risk. The risk of device failure, defined as the abandonment of the supraglottic airway device and replacement with a tracheal tube or another device, was also analysed. Sixty-five randomised clinical trials with 5823 participants were identified, involving 16 types of supraglottic airway device...

BACKGROUND: The development of supraglottic airway devices has revolutionized airway management during general anaesthesia. Two devices are widely used in clinical practice to facilitate positive pressure ventilation: the ProSeal laryngeal mask airway (pLMA) and the Classic laryngeal mask airway (cLMA). It is not clear whether these devices have important clinical differences in terms of efficacy or complications. OBJECTIVES: To compare the effectiveness of the ProSeal laryngeal mask airway (pLMA) and the Classic LMA (cLMA) for positive pressure ventilation in adults undergoing elective surgery...

BACKGROUND: Propofol is a widely-accepted medication for the successful insertion of laryngeal mask airway (LMA). When propofol is used alone, larger doses are required which can lead to cardiorespiratory distress resulting in hypotension and prolonged apnoea. The objective of this study was to evaluate the effect of premedication of midazolam on different doses of propofol for LMA insertion. METHODS: In this randomized clinical trial, eighty-six (86) patients who were scheduled to undergo elective surgery is supine position not requiring the need for tracheal intubation from September 2015 to 6 March 2016 were included...

BACKGROUND AND OBJECTIVES: The laryngeal mask airway (LMA) ProSeal is most commonly used supraglottic airway device; it is routinely inserted by blind technique. Although blind insertion technique is most widely used, there are many techniques which are available such as priming the drain tube with a guiding instrument such as a suction catheter, a gum elastic bougie, a Flexi-Slip Stylet, direct laryngoscopy, and even a fiber-optic bronchoscope (FOB). The present study was undertaken to compare and assess the placement of LMA ProSeal using blind versus direct laryngoscopy techniques using FOB...

BACKGROUND: Advanced airway management of combat casualties during scene-to-hospital air transport is challenging. Because of the short transport time, flight physicians of the Israeli military airborne combat evacuation unit are approved for the use of a laryngeal mask airway (LMA) in the event of failed endotracheal intubation (ETI). The aim of this study was to assess the effectiveness of LMA use during scene-to-hospital transport of combat casualties in Israel. PATIENTS AND METHODS: A retrospective cohort analysis of all combat casualties treated with ETI during scene-to-hospital transport over a 3-year period was carried out...

BACKGROUND AND AIMS: The ProSeal™ laryngeal mask airway (PLMA) has a soft cuff which tends to fold on itself during insertion, resulting in reduced first-attempt success rate. We compared the standard introducer technique of PLMA insertion with a novel method to prevent folding of the cuff using a Rüsch™ Stylet. METHODS: This randomised superiority trial included 120 American Society of Anesthesiologists I-II patients between 18 and 80 years, undergoing elective surgeries under general anaesthesia using a PLMA for airway management...

BACKGROUND AND AIMS: Second generation supraglottic airways are increasingly being used in surgical patients undergoing laparoscopic surgery. Preventing aspiration at higher airway pressures may be at the expense of a higher cuff pressure which can impair mucosal perfusion. We attempted to elucidate whether Ambu AuraGain™ (AAU) would provide a higher oropharyngeal leak pressure (OLP) with a lower mucosal pressure in comparison to ProSeal™ laryngeal mask airway (PLMA). METHODS: This was a prospective randomised study involving sixty patients undergoing laparoscopic cholecystectomy under general anaesthesia, using either AAU (Group AAU [n = 30]) or PLMA (Group PLMA [n = 30]) for elective ventilation...
