The Clinical Observation Of Emergence Agitation In Adult Patients During General Anesthesia After Hepatobiliary Surgery

Objective To investigate the reason about emergence agitation in adult patients during general anesthesia after Liver and Gallbladder surgery, and analysis the relationship between the narcotic drugs,hypothermia and the emergence agitation.Methods We elected sixty Liver and Gallbladder surgery patients whose ASA classification were the lever ofⅠ-Ⅱ. They were randomly assigned into two different way of general anesthesia, that is intravenous anesthesia totally which was maintained by propofol and combined with inhalation anesthsia which was maintained by inhaled anesthetics. The whole patient was induced by the same anesthesia, and all the patient connected nasal temperature probe to monitor the body temperature after mechanical ventilation. We observed the incidence and the lever of emergence agitation in hepatobiliary surgery patients after surgical operation. We also recorded the body temperature of patients when they were induced and completed the operation,anesthsia time,time to eye opening and extubation time; the third, the heart rate,the mean arterial blood pressure and SpO2 of the patients after surgery was collected.Results (1) No statistically significant differences in gender, age, height, weight, anesthesia time, time to eye opening and extubation time between the agitated patients and the non-agitatied patients ( p>0.05 ); (2) In the agitated patients, the level of excitement according to the sedation-agitation scale was: 21.67% of agitated patients (n=13), 18.33% of very agitatied patients (n=11) and 1.67% of dangerously agitated patients (n=1); (3) No statistically significant differences between agitated patients anesthetiazed with inhalational anesthetics and those anesthetiazed with propofol (P>0.05); (4) All patients showed a decline in their temperature during the surgery and the temperature which declined in greater extent than 1℃of agitated patient dropped obviously. However, the body temperature drop of non-agitatied patients was minor, mostly less than 1℃. After induction, no statistically significant difference about the body temperature between agitated patients and non-agitatied patient(sP>0.05), in the same way , no significant difference after surgery. However, the difference about the decrease of body temperature in the operation was statistically significant (P <0.05); (5) The heart rate and the mean arterial blood pressure of agitated patients after agitation was more faster and higer than those after procedure.Conclusion Application of inhaled anesthetics did not increase the incidence of emergence agitation in hepatobiliary surgery. There was no statistically significant differences in comparison with intravenous anesthesia drugs; Intraoperative hypothermia in liver and gallbladder surgery patients could inrease the incidence of emergence agitation.
