How blood loss varies in orthopedic prosthetic surgery with different techniques
Official title: Influence of Perioperative Strategies on the Extent of Total Blood Loss in Orthopaedic Prosthetic Surgery
Run by I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio · NCT07500350 · Data updated 2026-11-12
This study looks at how much blood patients lose during prosthetic joint surgery and whether factors like anesthesia, surgical method, or recovery practices influence that loss.

Is this trial a fit for you?
✓Likely a good fit
Adults (any ASA I–III) undergoing their first prosthetic joint implantation
✕Probably not a fit
Patients not receiving tranexamic acid prophylaxis or those undergoing reinterventions may not reflect the majority experience and may not benefit from the findings.

What this trial studies
This is a retrospective observational study evaluating blood loss in prosthetic orthopedic surgeries over a year. It analyzes preoperative hemoglobin and hematocrit, then tracks values on days 1–3 and day 7 after surgery. The study also looks at how intraoperative techniques and perioperative practices relate to bleeding, recovery, and complications. Primary goal is to understand the extent and variability of blood loss compared with published literature. Secondary outcomes include postoperative course, transfusion needs, and any complications related to bleeding or recovery.
Why it matters
Potential benefit: If successful, it could identify factors associated with reduced blood loss and better recovery after prosthetic joint surgery.
How similar studies have gone: Previous work has extensively studied blood loss in shoulder, hip, and knee replacements; this study adds a broader retrospective analysis within a single center.

Show full inclusion / exclusion criteria
Inclusion criteria: \- Adult patients in ASA Class I-II-III undergoing prosthetic surgery, as a first-time implant Exclusion criteria: * Patients who did not receive tranexamic acid prophylaxis (pre-operative and post- operative doses) and are therefore not comparable with the vast majority of cases. * Reintervention, as bleeding depends on a variable that is not constant, namely the initial implant
