Summary
High post-operative systolic blood pressure (SBP) over 150 mmHg and smoking increase the risk of compressive haematoma after thyroid surgery. Monitoring SBP in the post-anaesthetic care unit is crucial for patient safety.
Area of Science:
- Surgical Oncology
- Anesthesiology
- Vascular Surgery
Background:
- Post-operative haematoma is a significant complication following thyroid surgery.
- Identifying patients at high risk is essential for preventing adverse outcomes.
Purpose of the Study:
- To determine predictors of compressive post-operative haematoma after thyroid surgery.
- To identify patient risk factors for post-thyroidectomy bleeding.
Main Methods:
- Retrospective analysis of patients undergoing thyroid surgery.
- Matched pairs, case-control design to examine factors associated with post-operative haematoma.
- Regression analysis to identify significant risk factors.
Main Results:
- Seven out of 355 thyroid operations resulted in compressive post-operative haematoma.
- Systolic blood pressure > 150 mmHg in the post-anaesthetic care unit was a major significant factor (p = 0.002).
- Current smoking status was also a significant risk factor (p = 0.04).
Conclusions:
- Elevated post-anaesthetic systolic blood pressure (> 150 mmHg) is associated with increased hemorrhage risk after thyroid surgery.
- Smoking is another significant risk factor for post-operative haematoma.
- Close monitoring of blood pressure in the PACU is recommended for at-risk patients.
