Etomidate to Improve Outcome in Elderly Patients (EPIC)

Comparative Effect of Etomidate and Propofol on Major Complications After Abdominal Surgery in Elderly Patients

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

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame

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
the time to discharge from hospital		From end of surgery to discharge from hospital,on an average of 7 days
Post Operative Nausea And vomiting score	score:0,no nausea and vomiting; 1,nausea without vomiting; 2,vomiting	6 hours, 24 hours, 48 hours and 72 hours after end of surgery，approximately 6 hours, 24 hours, 48 hours and 72 hours respectively
pain on visual analogue scale		6 hours after end of surgery，approximately 6 hours
satisfaction on visual analogue scale by the patients	patients will be asked to score their satisfaction on anesthesia on a visual analogue, 0 is for extremely unsatisfied, 10 is for totally satisfied	24 hours after end of surgery
comfort on visual analogue scale by the patients	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	24 hours after end of surgery
incidence of hypotension during anesthesia	hypotension is defined as decrease of systemic blood pressure more than 20% of baseline	from start of surgery to end of surgery, on an average of 2.5 hours
incidence of hypertension during anesthesia	hypotension is defined as increase of systemic blood pressure more than 20% of baseline	from start of surgery to end of surgery, on an average of 2.5 hours
