Blood pressure should not be taken on the same side as a lumpectomy, especially if axillary lymph node dissection was performed, as this may increase the risk of lymphedema, a condition where fluid builds up in the arm due to disrupted lymphatic drainage from surgery. This recommendation is based on the most recent and highest quality study available, which suggests that taking blood pressure on the affected side can potentially restrict circulation and lymphatic flow, exacerbating the risk of lymphedema 1. The study, published in 2022, provides a summary of the evidence regarding limb precautions and evidence-based interventions to lower the risk of lymphedema after axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB).
Some key points to consider when taking blood pressure in patients who have undergone lumpectomy include:
- Avoiding the use of the affected arm for point-of-care testing, venipuncture, and blood pressure measurement to lower the risk of lymphedema 1
- Assessing the patient for risk factors of lymphedema before recommending selected evidence-based limb precautions 1
- Considering alternative sites like the leg or thigh for blood pressure measurement, or using non-invasive monitoring methods, if both sides have had surgery 2
- Maintaining this precaution indefinitely after lumpectomy with lymph node removal to minimize the risk of lymphedema 3
It is essential to note that while some studies suggest that the risk of lymphedema may be low if blood pressure is taken on the affected side according to current guidelines 2, the most recent and highest quality study available recommends avoiding this practice to minimize the risk of lymphedema 1. Patients should inform all healthcare providers about their surgical history to ensure proper precautions are taken during routine medical care.
