Comparative analysis of the cardiovascular circulation effects and the amount of oral secretions volume of surgery patients after laryngeal mask and tracheal intubation combined with epidural anesthesia

Objective To compare the effects of cardiovascular reaction after laryngeal mask and endotracheal intubation in patients of epidural anesthesia combined with surgery and a comparative analysis of the oral secretions volume.Methods Choose elevcitce general anesthesia associated with epidurdl opuo cases.Randomly divided into 2 groups:laryngeal mask airway group and endotracheal intubation set,each group 20 coses.Records before each group of patients with laryngeal mask airway or endotracheal intubation( T1 ),after induction( T2 ),1 minute( T3 ),3minute ( T4 ),intraoperative ( T5 ),remove cover(pipes) ( T6 ),to pull over and over 1 minute ( T7 ) and remove cover ( pipes )after 3minute(T8) SBP,DBP,HR,SpO2.Results Laryngeal mask or tracheal intubation prior to SBP,DBP,HR was not very different.Prior to extubation T6,T7,T8 of the SBP,DBP,HR between the two groups had significant differences The tracheal intubation group showed that the group with more than the larYngeal mask group.Particularly T6 endotracheal intubation group SBP ( 138 ± 35 ) mm Hg,DBP ( 92 ± 16) mm Hg,HR ( 96 ± 19 )/min showed higher LMA T6 group.Conclusion Laryngeal mask airway affects slightly effect on cardiovascular system in patients.LMA intubation could be achieved with satisfactory ventilation of the same tracheal intubation.LMA with hemodynamic stable,easy to operate,simple,throat discomfort,hoarseness of low.Laryngeal mask airway group was less than the amount of oral secretions endotracheal intubatior group and so on.
