From the Guidelines
For treating bilateral leg swelling caused by amlodipine use and prolonged recumbency, compression stockings with a pressure of 20-30 mmHg are recommended as the ideal and safe specification, as they provide sufficient compression to reduce fluid accumulation while being comfortable enough for daily wear. According to the study by Rochon et al 1, a minimum pressure of 20 to 30 mm Hg is recommended for compression therapy, with pressures of 30 to 40 mm Hg advised for more severe disease.
When selecting compression stockings, consider the following factors:
- The pressure specification: 20-30 mmHg is recommended for most patients, but 30-40 mmHg may be necessary for more severe edema.
- The length of the stockings: They should extend from the foot to just below or above the knee, depending on where the swelling occurs.
- The material and comfort: Choose breathable, moisture-wicking materials that will be comfortable for daily wear.
It is essential to note that compression therapy works by applying external pressure to the legs, improving venous return and preventing fluid accumulation in the tissues, as described by Rochon et al 1. This counteracts the vasodilatory effects of amlodipine and the reduced muscle pump activity from prolonged recumbency. If the swelling persists despite compression therapy, consult your healthcare provider as medication adjustments might be necessary. Additionally, caution is advised when the ankle-brachial index is <0.6, as it indicates an arterial anomaly needing revascularization, as noted in the study by Mosti and Partsch, cited in 1.
From the Research
Ideal and Safe mmHg Specification for Compression Stockings
To determine the ideal and safe mmHg specification for compression stockings to treat bilateral leg swelling caused by amlodipine use and prolonged recumbency, we need to consider the available evidence.
- The studies 2, 3 discuss the incidence of leg edema as a side effect of amlodipine, but they do not provide information on the ideal compression pressure for treating this condition.
- A study on dose finding for optimal compression pressure to reduce chronic edema of the extremities 4 found that compression stockings with a pressure between 20-40 mmHg showed a positive correlation between exerted pressure and volume reduction.
- Another study on the acute effect of wearing compression stockings on lower leg swelling and muscle stiffness in healthy young women 5 found that wearing below-knee graduated compression stockings for 30 minutes reduced lower leg swelling.
- A study on compression stockings reducing occupational leg swelling 6 found that calf-length compression stockings with a pressure range between 11 and 21 mmHg were able to reduce or totally prevent evening edema.
Key Findings
- Compression pressure between 20-40 mmHg is effective in reducing chronic edema of the extremities 4.
- Compression stockings with a pressure range between 11 and 21 mmHg can reduce or prevent evening edema 6.
- There is an upper limit beyond which further increase of compression pressure seems counterproductive, around 50-60 mmHg on the lower extremity 4.
Recommendations
Based on the available evidence, compression stockings with a pressure range between 11 and 21 mmHg or 20-40 mmHg may be effective in treating bilateral leg swelling caused by amlodipine use and prolonged recumbency. However, it is essential to consult a healthcare professional to determine the most suitable compression pressure for individual cases.
