About
This is a retrospective chart review to determine if neuraxial anesthesia is associated with worse outcomes after Primary Total Hip Arthroplasty.
Full description
The goal of this study is to determine if hypotensive neuraxial anesthesia is associated with worse outcomes in Primary Total Hip Arthroplasty. The plan to analyze the outcomes is listed below:
Primary outcomes:
Multiple logistic regression will be used to compute the adjusted odds ratios of any postoperative complications (MI, CVA, death) , adjusting for covariates including duration of intraoperative mean arterial pressure of less than pre-defined threshold, such as 55, or 60 mmHg mean blood pressure.
Sensitivity analyses will also consider the effects of intra-operative hypotension (IOH) defined as mean blood pressure of less than 40, 45, 50, 55, 60, and 65 mm Hg.
Secondary outcomes:
Multiple logistic regression will be to compute the adjusted odds ratios of individual postoperative complications, (such as MI, CVA, stroke) , adjusting for covariates including duration of intraoperative mean blood pressure of less than pre-defined threshold, such as 55, or 60 mmHg mean blood pressure. Sensitivity analyses will also be conducted to test the effects of extend of IOH on complications.
