Hemodynamic Effects of Continuous Spinal Anesthesia in Patient Aged Over 65 Years

Tunisia20 participantsStarted 2017-11-03

Plain-language summary

Compared to single-dose spinal anesthesia, continuous spinal anesthesia using small titrated doses of local anesthetic, was safe, efficient and provided better hemodynamic profile in elderly patients. The aim of this study was to investigate the hemodynamic effects of continuous spinal anesthesia in elderly patients undergoing knee arthroplasty. Investigators use the FloTrac sensor/Vigileo haemodynamic monitoring system to assess modification blood pressure, stroke volume and cardiac output during anesthesia and specialy after every bolus of spinal anesthesia, after inflating the tourniquet and after putting it off. they recorded number of hypotension episodes, ephedrine bolus and consumption until 2 hours after the end of surgery.
