Summary
Surgical time is a key factor for hidden blood loss (HBL) after unilateral open-door cervical laminoplasty (UOCL) for multilevel cervical spondylotic myelopathy (MCSM). Monitoring HBL is crucial, especially for procedures with longer surgical durations.
Area of Science:
- Neurosurgery
- Orthopedics
- Spine Surgery
Background:
- Multilevel cervical spondylotic myelopathy (MCSM) often requires surgical intervention.
- Unilateral open-door cervical laminoplasty (UOCL) is a common surgical technique for MCSM.
- Hidden blood loss (HBL) is a significant concern in spinal surgeries.
Purpose of the Study:
- To evaluate the extent of HBL after UOCL in MCSM patients.
- To identify potential risk factors associated with HBL in this patient cohort.
Main Methods:
- Retrospective analysis of 105 patients who underwent C3-7 UOCL for MCSM.
- Data collected included patient demographics, clinical factors, and surgical details.
- HBL calculated using the Sehat formula; risk factors identified through correlation and regression analyses.
Main Results:
- Median surgical time was 180.7 minutes.
- Median total blood loss (TBL) was 507.4 mL, with a median HBL of 201.7 mL.
- Surgical time was identified as an independent risk factor positively correlated with HBL (p<0.05).
Conclusions:
- Surgical time is a significant independent risk factor for HBL after UOCL for MCSM.
- HBL should be carefully monitored in patients undergoing UOCL, particularly those with anticipated prolonged surgical procedures.
