Filter by:This study aims to study the effectiveness of preoperatively nebulized dexamethasone in reducing the incidence and severity of Post Operative Sore Throat, POST in patients undergoing surgery under general anesthesia using the Ambu® AuraGainTM SGA device, with secondary aims of determining the effectiveness of dexamethasone in reducing post-operative cough severity and hoarseness of voice
Supraglottic airway devices with noninflatable cuff have advantages in omitting the cuff pressure monitoring and reducing potential pharyngolaryngeal complications. Typical devices without cuff inflation available are the i‐gel™ and the self‐pressurized air‐Q™ intubating laryngeal airway (air‐Q SP). The i-gel airway is a supraglottic airway management device made of thermoplastic elastomer, which is soft, gel-like, and transparent. It was designed to create a noninflating anatomical seal of the pharyngeal, laryngeal, and perilaryngeal structures while avoiding the compression trauma that can occur with inflatable SADs. The i-gel has evolved as a device that accurately positions itself over the laryngeal framework, providing a reliable perilaryngeal seal, and therefore no cuff inflation is necessary. Its advantages include easier insertion, minimal risk for tissue compression, and stability after insertion. The air-Q is a new SAD intended for use as a primary airway and an aid for tracheal intubation in situations of anticipated or unanticipated difficult airways. The intracuff pressure of air-Q dynamically equilibrates with the airway pressure and adjusts to the patient's pharyngeal and periglottic anatomy, potentially providing improved airway fit and seal. The anatomical and physiological changes that accompany ageing may have a significant influence on the efficacy and safety of SADs. The distinctive features of the air‐Q SP and i-gel may lead to a substantial difference in performance in the elderly, and it is planned a head-to-head comparison of these two devices in patients aged between 65 and 85 years.
Baska® mask (Proact Medical Systems, Frenchs Forest NSW, Australia) is displayed in figure 1 which is the latest addition to an array of supra-glottic airway devices in clinical use. It has a non-inflatable cuff, which is moulded to take up the shape of the supraglottic airway, potentially reducing the risk of oropharyngeal tissue and/or nerve damage induced by cuff over inflation, a known complication with other supraglottic airways. However, the cuff differs from other non-inflatable cuffs in that it is continuous with the central channel of the device. As the pressure increases with positive pressure ventilation ,the cuff itself is inflated which may improve the seal so reducing leak and make ventilation more efficient. The Baska mask has two ports (one for venting and other for gastric tube insertion ), so it incorporates an inlet that fits into the upper oesophagus and the dorsal surface of the cuff is moulded to direct any oropharyngeal contents away from the glottis and towards the side channels to which suction can be attached to facilitate aspiration of this space. These features may reduce the risk of pulmonary aspiration of secretions or gastric contents that accumulate in the supraglottic area. In addition, there is integrated bite-block, which reduces the risk of patients biting and blocking the airway. There is insertion tab which is an extended hand-tab attached to the cuff that permits the operator to control the degree of flexion of the device during the insertion. The Baska® mask is inserted in the neutral head position, which may reduce the need for neck manipulation. Initial experience with Baska®mask has demonstrated it to be a suitable airway device for procedures less than 2 hours or when endotracheal intubation is not required. I-gel airway (Intersurgical Ltd, Workingham, Berkshire,United Kingdom) is displayed in figure 2 which is second generation supraglottic airway devices (SADs) that was introduced in 2007. The I-gel is a single use (SADs) composed of a soft ,gel-like, non-inflatable cuff made from a thermoplastic elastomer. It has a widened , flattened stem with a rigid bite block that acts as a buccal stabilizer to reduce axial rotation and mal-positioning and a port for gastric tube insertion. It is a latex free device that does not require digital insertion into mouth of patient. With an epiglottic rest and wider and shorter stem, the I-gel gives an optimal view of the glottis with a fiber- optic scope so a shorter tube is ideal for endotracheal tube placement. Moreover, I-gel can be inserted as fast as classic LMA (Laryngeal Mask Airway) with adequate ventilation in patients and has no major airway complications. Therefore, it could be a good alternative to classic LMA in emergency airway management or general anesthesia.
The aim of the study is to compare the performance of two supraglottic airway devices (SGA), the new Ambu AuraGain and the LMA Supreme, in sixty female patients undergoing gynaecologic laparoscopy in the trendelemburg position. Primary outcome is the airway seal pressure. Secondary outcomes are ease of insertion, quality of ventilation, endoscopic view of the glottis, gastric tube passage and complications.
Supraglottic airway devices (SADs) are well established in pediatric anesthetic practice. The pediatric i-gel and the self-pressurised air-Q (air-Q) are new supraglottic airway devices for children. The i-gel is made of a soft, gel-like elastomer with a noninflatable cuff. The air-Q is a new single-use device that may optimise the airway seal while reducing the potential for postoperative complications such as sore throat. The overall structure of the air-Q SP is identical to the original air-Q, except with regard to the inflatable cuff. The aim of this randomized trial was to compare the clinical performance of the i-gel and the air-Q SP.
