Abstract
Objective Observed in single lung ventilation,right the microphones on auxiliary anesthesia hemodynamic, whether to help to improve the single lung ventilation lung ventilation/blood flow abnormalities.Methods 60 cases of esophageal cancer radical under one-lung ventilation were divided into control group and experimental group.Control group 0.9% saline injec-tion 10 mL after anesthesia induction,the experimental group after anesthesia induction right set beauty holds the mi 0.6 mu g/kg (input) 10 minutes.Observe two groups of related indicators: single lung ventilation time,operation time,airway pressure,oxygen partial pressure;Observe preoperative,15 minutes before intubation and after intubation and after intubation,cut skin,into the chest,single lung ventilation when 60 minutes,90 minutes of single lung ventilation,double lung ventilation 15 minutes time point of the mean arterial pressure (MAP),heart rate (HR);Observe preoperatively,single lung ventilation 60 minutes,90 minutes of one-lung ventilation and oxygen index.Results This study results show that the oxygen and index in preoperative point in time,the ex-perimental group there was no statistically significant difference compared with control group (P>0.05);Oxygen index and one-lung ventilation 60 minutes,single lung ventilation in 90 minutes,the experimental group compared with control group difference was sta-tistically significant(P<0.05),its mechanism is probably reduced the single lung ventilation cause acute lung injury.HR,MAP before intubation and after intubation,15 minutes after intubation,cutting leather,into the chest,single lung ventilation when 60 minutes, 90 minutes of single lung ventilation,double lung ventilation 15 minutes time,the experimental group compared with control group difference was statistically significant (P<0.05).Conclusion In single lung ventilation,right the mi auxiliary anesthesia hemody-namic more smoothly,and oxygen index increased,contribute to the improvement of the lung ventilation of single lung ventilation/abnormal blood flow.关键词
