Effect of Pressurized Cement Insertion on Cardiopulmonary Parameters during Cemented Hip Hemiarthroplasty: A Randomized Prospective Study.

PURPOSE

We aimed to investigate the cardiopulmonary effects of pressurized cement insertion in elderly patients undergoing cemented hip hemiarthroplasty.

MATERIALS AND METHODS

We conducted a randomized prospective study on elderly patients undergoing cemented hip hemiarthroplasty. Patients were divided into pressurized and non-pressurized groups based on the pressure application during cement insertion. We measured mean arterial blood pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), arterial blood gases and serotonin concentration in blood. These variables were measured before bone cement insertion, and 3 and 5 minute after insertion. They were also measured immediately and 15 minutes after reduction.

RESULTS

In cemented hip hemiarthroplasty, there were no significant change in MAP (P=0.92), SBP (P=0.85), DBP (P=0.98), HR (P=0.97) and serotonin concentration over time. There were no statistically significant difference between the two groups in MAP, SBP, DBP, HR, PO2, PaCO2, SaO2 and serotonin concentration, though three minutes after cement insertion, both groups showed decreases in SBP, DBP and MBP.

CONCLUSION

The pressurization method in cemented hip hemiarthroplasty was not found to be related with development of bone cement syndromes in elderly patients.
