Abstract
Background In the last few years, a number of supraglottic airway devices have been introduced in the clinical practice of airway management, trying to offer a simple and effective alternative to the endotracheal intubation. These devices are designed to overcome the disadvantages of endotracheal intubation such as soft tissue injury and exaggerated haemodynamic response. Purpose The aim of the present study was to compare between the I-gel and the Air-Q intubating laryngeal airway as alternative supraglottic airway devices during general anaesthesia with controlled ventilation in paediatrics. Patients and methods Sixty ASA grade I and II children, aged 3–6 years, and scheduled to undergo elective surgery under general anaesthesia with controlled ventilation in supine position were randomly categorized into two equal groups (30 patients each): group I, in which the I-gel was used to maintain a patent airway during anaesthesia; and group II, in which Air-Q intubating laryngeal airway was used to maintain a patent airway during anaesthesia. After induction of anaesthesia and muscle relaxation, we measured ease of insertion, time and number of trials to successful insertion, airway sealing pressure, fibrescopic view of the glottis, maintenance success, haemodynamic responses, airway interventional requirements and any other complications. Conclusion This study showed that both supraglottic airway devices are suitable for positive pressure ventilation with high success rates in children undergoing elective surgeries. It was found that the I-gel has a shorter time of insertion and a higher airway sealing pressure, whereas Air-Q has a better fibrescopic view of the glottis.
