[Preoperative concentration of plasma fibrinogen as a predictor of bleeding in total hip arthroplasty].

Introduction: Total hip arthroplasty is popular for its success in treating coxarthrosis, its associated with substantial blood loss. Significant bleeding causes complications such as increase in hospitalization days, higher costs, exposing the patient to complications associated with blood transfusion. The aim of the study is to investigate the association between preoperative plasma fibrinogen concentration and trans-surgical bleeding and determine fibrinogen level cut-off to present greater trans-surgical bleeding.

Incidence and risk factors for acute kidney injury: a prospective, randomized, single-blind clinical trial comparing total knee arthroplasty with and without tourniquet.

Purpose: Identify the incidence and risk factors for acute kidney injury (AKI) following total knee arthroplasty (TKA) with and without tourniquet.

Material And Methods: 100 patients were randomized into two groups. Postoperative AKI was defined as the postoperative creatinine level 0.

Risk factors for amputation in periprosthetic knee infection.

Treatment for prosthetic knee replacement is becoming more common. Infection is an arthroplasty-related complication leading to prolonged hospitalization, multiple surgical procedures, permanent loss of the implant, impaired function, impaired quality of life and even amputation of the limb. Previous studies have evaluated the risk factors associated with periprosthetic knee infection, but scarce information related to risk factors associated with amputation in this group of patients is available.
