Insights
Pressurized cement insertion during hip hemiarthroplasty in elderly patients did not significantly affect cardiopulmonary parameters or serotonin levels. This method was not linked to bone cement syndrome development.
Area of Science:
- Orthopedic Surgery
- Cardiopulmonary Physiology
- Biomaterials Science
Background:
- Cemented hip hemiarthroplasty is a common procedure in elderly patients.
- Bone cement insertion can potentially cause hemodynamic changes.
- Bone cement syndrome is a known complication.
Purpose of the Study:
- To evaluate the cardiopulmonary effects of pressurized cement insertion.
- To assess the impact on serotonin concentration.
- To determine the association with bone cement syndrome in elderly patients.
Main Methods:
- Randomized prospective study comparing pressurized and non-pressurized cement insertion.
- Monitored hemodynamic parameters (MAP, SBP, DBP, HR) and blood gases.
- Measured serotonin levels pre- and post-cement insertion and reduction.
Main Results:
- No significant changes in MAP, SBP, DBP, HR, or serotonin concentration over time.
- No significant differences between pressurized and non-pressurized groups.
- Transient decreases in SBP, DBP, and MBP observed in both groups post-insertion.
Conclusions:
- Pressurization during cemented hip hemiarthroplasty is not associated with bone cement syndrome in the elderly.
- The procedure appears hemodynamically stable regarding measured parameters.
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.
