- NCT02910206
- Lead Sponsor
- Zhihong LU
- Brief Summary
Elderly patients have high mortality and postoperative complications rate after surgery, especially postoperative cardiac complications. A meta-analysis revealed haemodynamic intraoperative events significantly increased the risk of postoperative cardiac complications.To limit the risk, optimize the intraoperative management of circulation is essential. Anesthetic drug may effect on the haemodynamic intraoperative, reduction of postoperative complications should aimed at choosing the optimal anesthetic drug with minimal effect on haemodynamic.So this study is to explore the comparative efficacy and safety of anesthetic drug (etomidate or propofol) in elderly patients

- Primary Outcome Measures
Name Time Method Number of participants with complications defined by ICD (International codes of diseases)-9 From the moment of giving sufentanil to the moment of discharge from hospital,up to 7 days
- Secondary Outcome Measures
Name Time Method the time to discharge from hospital From end of surgery to discharge from hospital,on an average of 7 days the time to awake from anesthesia From stopping etomidate or propofol infusion to awake, approximately 30 minutes the time to withdraw tracheal tube from anesthesia From end of etomidate or propofol infusion to recovery of spontaneous breathing and withdrawal of tracheal tube,approximately 30 minutes the time to discharge from post-anesthesia care unit From admit into post-anesthesia care unit to discharge from post-anesthesia care unit,on an average of 30 minutes Post Operative Nausea And vomiting score 6 hours, 24 hours, 48 hours and 72 hours after end of surgery，approximately 6 hours, 24 hours, 48 hours and 72 hours respectively score:0,no nausea and vomiting; 1,nausea without vomiting; 2,vomiting
pain on visual analogue scale 6 hours after end of surgery，approximately 6 hours satisfaction on visual analogue scale by the patients 24 hours after end of surgery patients will be asked to score their satisfaction on anesthesia on a visual analogue, 0 is for extremely unsatisfied, 10 is for totally satisfied
comfort on visual analogue scale by the patients 24 hours after end of surgery patients will be asked to score their comfort during and after anesthesia on a visual analogue, 0 is for extremely unsatisfied, 10 is for totally satisfied
incidence of hypotension during anesthesia from start of surgery to end of surgery, on an average of 2.5 hours hypotension is defined as decrease of systemic blood pressure more than 20% of baseline
incidence of hypertension during anesthesia from start of surgery to end of surgery, on an average of 2.5 hours hypotension is defined as increase of systemic blood pressure more than 20% of baseline
percentage of patients needed vasoactive agents during anesthesia from start of surgery to end of surgery, on an average of 2.5 hours concentration of serum Adrenocorticotropichormone(ACTH) by radioimmunoassay 24hours,48hours and 72hours after extubation，approximately 24 hour, 48 hour and 72 hour respectively concentration of serum Cortisol by radioimmunoassay 24hours,48hours and 72hours after extubation，approximately 24 hour, 48 hour and 72 hour respectively concentration of serum aldosterone by radioimmunoassay 24hours,48hours and 72hours after extubation，approximately 24 hour, 48 hour and 72 hour respectively death by 6 months after surgery from end of surgery to 6 months after surgery death by 12 months after surgery from end of surgery to 12 months after surgery
