Autoclaving impairs the connector-tube bond of the laryngeal mask airway but not its airtightness.

چکیده
The general-purpose laryngeal mask airway (LMA) is re-usable when undamaged, and cleaned and autoclaved correctly. We had found weakening of the silicone adhesive that bonds the connector of the LMA to the tube. We report that repeated autoclaving damaged the adhesive such that the connector could be rotated in the tube after the 12th autoclave cycle in almost all of the LMA tested. The damage to the adhesive did not affect the airtightness of the junction, which appears to be maintained by the material properties of the connector and tube and by the shape of the join.

Post-operative sore throat is one of the most common complications and complaints of patients after general anesthesia especially in operations that need endotracheal intubations. Its causes are: size of endotracheal tube and type of its cuff, inadequate airway humidification, trauma during intubation and suctioning, high flow of inspiratory gases, surgical manipulation of airway and adjacent o...

Background and purpose: The method of anesthesia affects intraocular pressure (IOP), especially general anesthesia which is sometimes administered with endotracheal tube (ETT) insertion. The aim of this research was to compare the effect of laryngeal mask airway (LMA) and ETT on intraocular pressure in cataract surgery. Materials and methods: In a single blind randomized clinical trial, 61 pat...

Aims and background: Airway management is one of the key skills in managing and treating of critical patients. In hospital departments before reaching an anesthesiologist or experienced team, this task lies with the nurses who have not been trained enough in this field. This study was conducted to evaluate the ability of nurses before and after a manikin-based workshop for securing the airway ...

Introduction: The laryngeal mask airway (LMA) is a safe method to establish airway control during general anaesthesia. In otolaryngology surgery, the use of a LMA is well established in ear surgery; however, the use of a LMA during open neck procedures remains controversial. We report a case in which the pharyngeal distortion by the LMA cuff resulted in an iatrogenic complication. Case Report...
