Elderly With Hip Fracture and Perioperative Hemoglobin and Perfusion Index Levels

Contionuous Perioperative Hemoglobin and Perfusion Index Measurements in Elderly Patients With Hip Fracture and Post Operative Delirium

The overall aim of the study is to investigate the time difference in the diagnosing of anemia among elderly with hip fracture, between measurements with standard blood samples and non-invasive SpHb-measuring. Another aim is to investigate the relationship between perfusion index and prolong perioperative anemia and the potential impact on perioperative complications.

Immediately after admission and diagnosis of a hip fracture the patients will be monitored with Masimo SpHb. The Patients will be continuously measured until the third day after surgery. The Monitors Hb and PI data but not the SpO2% will be blinded to all participating healthcare personnel.The first three postopertive days the patiens will daily be examined to determined it they have developed delirium.

All perioperativ complications in that period will be monitored.

Inclusion Criteria:

• Age ≥ 65 years
• Primary hip fracture requiring surgery
• Patients able to give informed consent
• Patients who are able to undergo the Hospitals standardized fast track
• Perioperative care regimen for hip fracture including are pre operative placed epidural

Exclusion Criteria:

• Patients who can not co-operate to have a sensor attach to the finger continuous for 4 days.
