Perioperative medicine & outcomes
Time-course of heart rate variability after total hip arthroplasty
Authors' conclusion
We provide the first detailed description of perioperative time-course of HRV and orthostatic symptoms in fast-track THA, showing reduced HRV after surgery for at least a week, and that HRV changes are sensitive to time of day and timing before and after surgery.
Study context
- Population
- Patients undergoing fast-track total hip arthroplasty (THA)
- Participants
- 24 patients
- Outcome
- Time-course of perioperative HRV
- Follow-up
- 4 days before until 9 days after THA
Methodological detailscontinuous heart rate variability (HRV) measurement, procedure-specific
- Continuous HRV measurement
- Procedure-specific
Main finding
As reported in the abstract
HRV time-course
- SD between normal-to-normal beats and total power of HRV reduced for at least 9 days after THA
- Trend towards increased HRV leading up to the day of surgery
- Low-/high-frequency power balance reduced in the postoperative evenings
Observational data: associations, not effects.
Further findings
Orthostatic symptoms (Orthostatic Discriminant and Severity Scale)
- Increased orthostatic intolerance symptoms on the first postoperative day; pain, fatigue and weakness decreasing after the first postoperative day
Hospital stay
- Median hospital stay
- 1 day
