Influence Of Hemodynamics In Three Different Endotracheal Intubation Methods In Patients With Abdomen Operation

Objective.To analyse the Influence of hemodynamics in three differenten dotracheal intubation method in patients with abdomen operation.Methods:Select from September2012to September2013proposed intubation under general anesthesia on90patients undergoing elective general surgery were randomly divided into group A (GSVL group,30cases), group B (MDLS group,30cases) and group C (FOB group,30cases). After induction of anesthesia, using three mirrors were orotracheal intubation, recorded before anesthesia induction (To), after induction (T1), intubation (T2), after intubation1min,3min,5min (T3-T5) of hemodynamic parameters (SBP, DBP, MAP, HR).Results:Compared with the TO after anesthesia induction, SBP, DBP, MAP of three groups of T1is decreased (P<0.05), HR change without statistical significance, TO and T1the indicators change there was no significant difference between the three groups. Compared with T1, T2time three groups all indexes were significantly increased (P<0.05). Compared with T0, T2time FOB group of SBP, DBP, MAP and HR were significantly increased (P<0.05), compared with MDL and GS group, FOB group all index increased significantly (P<0.05). GS compared with MDL group had no significant difference. Compared with T1, T2time MDL group with a significant rise in GS group, all indexes, MDL endotracheal intubation in HR is significantly higher than that of GS group (P<0.05). FOB HR was significantly higher than that of GS group and MDL. Compared with T1, T3, T5time all indexes of three groups were significantly increased.(P<0.05). Compared with T0, T3, T5time GS group all index compared with MDL group was slightly lower, but there was no significant difference, FOB group compared with GS and MDL group there were significant differences (P<0.05). Compared with T2, T3, T5time GS there was no significant difference between the groups with and MDL, FOB group compared with GS, MDL group there were significant differences (P<0.05). Conclusion:1, visual laryngoscope in tone tube intubation, hemodynamic response caused by close to direct laryngoscope2, visual laryngoscope, fiber mirror in difficult airway plays an important role.
