BACKGROUND Supraglottic airway devices are increasingly important in clinical anesthesia and prehospital emergency medicine, but there are only few data to assess the risk for aspiration. We designed this study to compare the seal of seven supraglottic airway devices in a cadaver model of elevated esophageal pressure. METHODS The classic laryngeal mask airway, laryngeal mask airway ProSeal, i...

Since these methods present a ce...
In view of the local cracking and leakage water-wall pipe Subcritical Boiler in a thermal power plant, mechanism water wall was studied by means macroscopic analysis, chemical composition metallographic structure, Brinell hardness test, tensile test at room temperature scanning electron microscopy. The results show that there is no misuse materials or unqualified cracked leaked pipe. There are ...
