This information is intended only for healthcare professionals:
The recommended dose is 0.5 ml to 3.0 ml per patient. Generally, a dose of 3.0 ml is sufficient, but some patients may need higher doses. The total dose should not exceed 8.7 ml per patient. The useful image duration is 2.5-4.5 minutes for a dose of 0.5-3.0 ml.
OPTISON may be administered repeatedly, however, clinical experience is limited.
The smallest dose should be used for adequate opacification of cavities, as higher doses produce blocking effects in the image that may obscure important information.
As with all parenteral products, a visual inspection of the OPTISON vials should be performed to check the integrity of the container.
The vials are for single use only. Once the rubber stopper is pierced, the contents should be used within 30 minutes and any unused product should be discarded.
After standing, OPTISON forms a white microsphere layer at the top of the liquid phase, which requires resuspension before use. Homogeneous white suspension after resuspension.
Follow these instructions:
Warning: Never use any other type of access that is not an open flow connection. If it is injected otherwise, the bubbles of OPTISON will be destroyed.
Immediatelyafter the injection of OPTISON, 10 ml of sodium chloride 9 mg/ml (0.9%) injection or glucose 50 mg/ml (5%) injection should be injected at a rate of 1 ml/s.
Alternatively, the flush may be performed by perfusion. The perfusion equipment should be connected to the 3-way stopcock and the intravenous perfusion should be started at a "keep open" (TKO) rate. Immediately after injecting OPTISON, the intravenous perfusion should be opened fully until the contrast starts to disappear from the left ventricle. Then, the perfusion rate should be returned to the TKO rate.
