Hemodynamic Stability Between Spinal and General Anesthesia in Patient Undergoing Primary Total Knee Arthroplasty: A Retrospective Study.

ABSTRACT:

Background

Total knee arthroplasty (TKA) is a common surgical procedure that may be associated with blood loss. The aim of this study is to evaluate intraoperative hemodynamic stability during TKA under general (GA) or spinal anesthesia (SA).

Methods

Any adult undergoing primary TKA under GA or SA was retrospectively selected over a 10-year period and compared. The primary outcome was the presence of intraoperative hemodynamic instability, defined by starting a norepinephrine infusion, as the variation of the patient's blood pressure exceeded 30% of its baseline value for more than 5 min. Secondary outcomes included intraoperative dose of ephedrine, phenylephrine, blood loss, and volume of fluid administered. Demographic and intraoperative anesthetic variables associated wit
