Abstract

Background: Postoperative cognitive dysfunction in the elderly greatly affects the quality of recovery after surgery. Our research question is: “What is the rate of postoperative cognitive dysfunction in the elderly after spinal anesthesia for hip and knee joint arthroplasty in postoperative 5 days?”

Materials and Methods: Elderly patients (≥ 60 years) receiving spinal anesthesia for joint arthroplasty. Design of this study is longitudinal observational, prospective, single-center.

Results: 22,5% of elderly patients had postoperative cognitive dysfunction for joint arthroplasty and received spinal anesthesia in the first 5 days of surgery. Multivariable Cox regression analysis had 3 risk factors: use of sedative midazolam during surgery (p = 0,002); perioperative blood transfusion of more than 2 units of red blood cells (p = 0,01) and moderate pain level on day 1 (p = 0,008).

Conclusions: Of all the 107 patients, 24 (22,5%) developed postoperative cognitive dysfunction in postoperative 5 days, occurring on medium 2 days after surgery. There are 3 risk factors for postoperative cognitive dysfunction: the use of sedative midazolam during surgery, perioperative blood transfusion of more than 2 units of red blood cells and moderate pain level on day 1.
