Laryngeal mask airway air Q

STUDY OBJECTIVE: Various randomized controlled trials and a meta-analysis have compared i-gel™ and laryngeal mask airway Supreme™ (LMA-S™) in adult patients and found that both the devices provided equivalent oropharyngeal leak pressure (OLP). However, no randomized controlled trial has compared air-Q™ with i-gel™ and LMA-S™ in adult patient. Hence, we designed this study to compare air-Q™ with LMA-S™ and i-gel™ in adult patients. MATERIALS AND METHODS: A total of 75 adult patients of the American Society of Anesthesiologists physical status I/II of both sexes, between 18 and 60 years, were included in this prospective randomized controlled trial conducted in a tertiary care center...

BACKGROUND AND AIMS: Air-Q intubating laryngeal mask airway (ILA) is used as a supraglottic airway device and as a conduit for endotracheal intubation. This study aims to assess the efficacy of the Air-Q ILA regarding ease of insertion, adequacy of ventilation, rate of successful intubation, haemodynamic response and airway morbidity. METHODS: Sixty patients presenting for elective surgery at our Medical College Hospital were selected. Following adequate premedication, baseline vital parameters, pulse rate and blood pressure were recorded...

BACKGROUND AND AIMS: Air-Q™ is a newly introduced airway device, which can be used to facilitate endotracheal intubation. The primary aim of this study was to assess whether use of two different endotracheal tubes (ETTs) (standard polyvinyl chloride [PVC] and reinforced PVC) increases the success rate of blind intubation through Air-Q™ (Group Q) when compared with intubating laryngeal mask airway (ILMA- Fastrach™) keeping ILMA as control (Group I). METHODS: One hundred and twenty patients aged between 18 and 60 years with American Society of Anesthesiologists physical status I-II, undergoing elective surgery under general anaesthesia, were enrolled into this prospective, randomised, case-control study to compare the success rate of tracheal intubation between ILMA (Fastrach™) and Air-Q™ intubating laryngeal airway...

We present a case of an 18-year-old male who underwent strabismus operation under general anesthesia. In his childhood, tracheostomy had been performed for the repair of cleft lip and palate. His Mallampati classification was IV and preoperative endoscopic examination revealed megaloglossia and severe airway narrowing. For possible difficult airway, intubating laryngeal airway (air-Q®, size 2.5) was used for tracheal intubation. Following insertion of air-Q®, trachea was intubated via air-Q® guided with fiberscope...

Patients with Klippel-Feil syndrome (KFS) frequently encounter difficult airway management due to skeletal abnormalities, including fusion of two or more vertebrae and short neck. We report successful tracheal intubation using the air-Q supraglottic airway device (air-Q). A 46-year-old woman (height, 149 cm; weight, 62 kg) with KFS was scheduled to undergo vertebral arch plasty for cervical spondylotic myelopathy. She could open her mouth sufficiently but could not tilt her head due to C1-3 fusion. Following administration of fentanyl 100 microg and propofol 120 mg, mask ventilation was achieved with jaw thrust maneuver...

BACKGROUND: Flexible laryngeal mask airway is a commonly used supraglotic airway device (SAD) during ophthalmic surgeries. Air-Q intubating laryngeal airway (ILA) is a newer SAD used as primary airway device and as a conduit for intubation as well. Available literature shows that air-Q performs equal or better than other SADs in children and adults. However, limited data is available using air-Q in infants and small children <10 kg. So, our aim was ‘To compare the performance and efficacy of these two devices in infants and small children’...

PURPOSE: In the 2010 American Heart Association guidelines, supraglottic devices (SGDs) such as the laryngeal mask are proposed as alternatives to tracheal intubation for cardiopulmonary resuscitation. Some SGDs can also serve as a means for tracheal intubation after successful ventilation. The purpose of this study was to evaluate the effect of chest compression on airway management with four intubating SGDs, aura-i (aura-i), air-Q (air-Q), i-gel (i-gel), and Fastrack (Fastrack), during cardiopulmonary resuscitation using a manikin...

A 68-year-old man was diagnosed with severe pharyngeal edema after neck lymph node dissection for cancer of the external ear canal. He was scheduled for an emergency tracheotomy, but preoperative fiberoptic laryngoscopy revealed airway and glottic obstruction due to severe pharyngeal edema. As difficult mask ventilation and tracheal intubation were anticipated, intubation under spontaneous ventilation was performed to avoid a "can't ventilate, can't intubate" situation. The first attempt to intubate the patient using the Pentax-AWS Airwayscope with a thin Intlock resulted in failure due to hindered visualization of the glottis...

BACKGROUND AND OBJECTIVES: Supraglottic airway devices are increasingly used in anesthesia and emergency medicine as a rescue for intubation and ventilation. This study was designed to investigate the air-Q(®) supralaryngeal device and compare it with the ILMA-Fastrach™ for airway rescue and intubation. PATIENTS AND METHODS: The devices were inserted in 80 patients (40 patients in each group) according to manufacturer' instructions. An inspiration pressure of 20cmH2O was applied through a ventilator for checking air leaks...

BACKGROUND: Supraglottic airway devices are often used in airway management to facilitate tracheal intubation. Knowledge of the distance from the grille of the device to the patient's vocal cords is essential for the safe passage of the tracheal tube below the vocal cords. OBJECTIVES: To assess the distance from the glottis to the grille of three supraglottic airway devices [LMA (LMA Unique), Air-Q (Air-Q Intubating Laryngeal Airway Reusable) and CobraPLA (Cobra Perilaryngeal Airway)] and their safe usage as intubation conduits...

This review discusses the history, developments, benefits, and complications of supraglottic devices in prehospital care for adults and pediatrics. Evidence supporting their use as well as current controversies and developments in out-of-hospital cardiac arrest and rapid sequence airway management is discussed. Devices reviewed include the Laryngeal Mask Airway, Esophageal Tracheal Combitube, Laryngeal Tube, I-Gel, Air-Q, Laryngeal Mask Airway Fastrach, and the Supraglottic Airway Laryngopharyngeal Tube (SALT)...

A 46-year-old man was diagnosed with descending colon cancer and was planned to undergo left hemicolectomy under general anesthesia. His body mass index was 42.6 and due to his small mouth and jaw, we anticipated difficult mask ventilation and tracheal intubation. To avoid 'can't ventilate, can't intubate', we first inserted a size 3.5 air-Q laryngeal airway under moderate sedation, maintaining spontaneous ventilation. After confirming sufficient assisted ventilation, we used a bronchofiberscope to visualize placement of a gum elastic bougie in the trachea via the air-Q...

PURPOSE: The air-Q® intubating laryngeal airway (ILA) is a supraglottic device (SGD) designed specifically to function as both a primary airway and a bridging device and conduit for fibreoptic intubation in difficult airway scenarios. This observational study evaluated the usability and performance characteristics of pediatric air-Q ILA sizes 1.0, 1.5, 2.0, and 2.5 when used as a primary airway. METHODS: One hundred ten children, American Society of Anesthesiologists physical status I-III and undergoing elective surgery, received a weight-appropriate air-Q ILA following induction of anesthesia...

A 79-year-old man was diagnosed with maxillary cancer and underwent total maxillectomy under general anesthesia. The oropharyngeal airway was needed for efficient mask ventilation during anesthesia induction. The maxilla was totally resected and reconstructed with skin from a femoral flap. Tracheal extubation was considered to be difficult given that mask ventilation was contraindicated due to reconstruction of the maxilla. After inserting a tube exchanger (TE) into the trachea, the tracheal tube was exchanged with an air-Q laryngeal airway through the TE...

The intubating laryngeal airway, air-Q ILA, was recently introduced in Japan. It has been used in adult patients for difficult airway management; however, there are few reports available on its use in pediatric patients. We report the use of the air-Q ILA in predicted difficult airway management in a 16-month-old patient with Apert syndrome characterized by acrocephalosyndactyly undergoing a syndactyly operation. It was somewhat difficult to keep his airway with a facemask, and an air-Q ILA was inserted. Following the ventilation via air-Q ILA, tracheal intubation guided by a tracheal fiberscope was attempted through the air-Q ILA...

AIMS: The laryngeal mask airway-ProSeal™ can be inserted digitally, by introducer tool, or by railroading it over a bougie placed first in the patient's oesophagus, which is highly successful, but as originally described, requires an assistant. An unassisted bougie-guided placement technique has also been described, but no data on its effectiveness have been reported. METHODS: We reviewed data collected during a randomized, controlled trial comparing the air-Q(®) Intubating Laryngeal Airway and LMA-Proseal™, in which all LMA-Proseal™ devices were inserted using the unassisted (one-operator), bougie-guided placement technique...

BACKGROUND: Air-Q™ intubating laryngeal airway (ILA) has been used successfully as a conduit for tracheal intubation in pediatric difficult airway. However, its use as an airway device and conduit for intubation in infants is not yet evaluated. AIMS: The primary objective was to evaluate ILA as a conduit for tracheal intubation in infants, and secondary objectives were to evaluate ILA in terms of ease of insertion and ventilation, oropharyngeal leak pressure (OLP), glottic view, and complications...

BACKGROUND: Recent resuscitation guidelines for infant cardiopulmonary resuscitation (CPR) emphasise that rescuers should minimise the interruption of chest compressions. To that end, supraglottic devices such as laryngeal mask airways (LMAs) are suggested as a backup for airway management during infant CPR. We therefore compared the utility of the air-Q(®) LMA (air-Q) with that of the Soft Seal(®) LMA (Soft Seal) for infant CPR in an infant manikin. METHODS: Twenty-four novice doctors in the anaesthesia department performed insertion and ventilation with air-Q and Soft Seal on an infant manikin with or without chest compression...

OBJECTIVES: The purpose of this randomized crossover study was to evaluate the feasibility of the air-Q intubating laryngeal airway (ILA) in clinical practice when compared with the Laryngeal Mask Airway-Unique(™) (LMA-U), the current standard of care for primary airway maintenance. AIM: We hypothesized that the ILA would have better airway seal pressures and laryngeal alignment than the LMA-U in anesthetized nonparalyzed children. BACKGROUND: The ILA is a newer supraglottic airway for children with design features that allow it to be used for primary airway maintenance and as a conduit for tracheal intubations...

We performed a prospective, open-label, randomised controlled trial comparing the air-Q(®) against the LMA-ProSeal™ in adults undergoing general anaesthesia. One hundred subjects (American Society of Anesthesiologists physical status 1-3) presenting for elective, outpatient surgery were randomly assigned to 52 air-Q(®) and 48 ProSeal devices. The primary study endpoint was airway seal pressure. Oropharyngolaryngeal morbidity was assessed secondarily. Mean (SD) airway seal pressures for the air-Q(®) and ProSeal were 30 (7) cmH (2) O and 30 (6) cmH(2) O, respectively (p = 0...
