ABSTRACT
Objective To design a multifunctional laryngeal mask development and can be used in clinical tracheobronchial foreign body removal, surgical lung lavage, lung surgery to stop bleeding and lung biopsy. Methods Three-way Laryngeal Mask is improved base on the traditional laryngeal mask, it adds a three-way channel(adapter), one end(port) of the threeway channel connected with the laryngeal mask, another end covered the seal cap from which can insert the fiberoptic bronchoscope or endoscope, one another end is a 15mm standard interface for connecting with the respiratory machine or anesthetic machine. The fiberopticscope or other kinds of endoscope will be inserted from the end of seal cap through the laryngeal mask body, the glottis enters trachea to bronchus. The standard end can be connected with the respiratory machine, in the process of operation can adjust the ventilation by manual control or machine-controlled. Results Through the clinical application testing, the use of the multifunctional laryngeal mask for all lung diseases surgery is successful completely, the degree of satisfaction is 100% and the effect of ventilation is excellent. Conclusion The multifunctional laryngeal mask can be widely used in the clinical various lung disease operation with safe, reliable, effective and advantages of fewer complications, which significantly expand the traditional use of laryngeal mask and considerably increase the security of anesthesia and operation.
ABSTRACT
Acute necro-hemorrhagic pancreatitis (ANHP) was induced in rats by intra-pancreatic duct injection with a mixed solution of bile salt and trypsin. After 6- to 30-hr of operation the increase of plasma lipidperoxidant (LPO) levels from 4.67 to 20.5 nmol/ml and the fall of plasma amylase levels from 6577 to 2629 U were observed in the rats with ANHP. The values of the plasma LPO at 10-,20-,and 30-hr in the rats with ANHP were significantly higher than those in the control (P
