Transcervical. When carrying out hysterosalpingography, 2.5 ml (using an intrauterine balloon catheter) is injected, in the study of fallopian tubes - an additional 1-2 ml; the maximum dose is 15 ml. The drug is available in vials: one (volume of 20 ml) contains 0.3 g of granulate, in the other (volume, too, 20 ml) - 13.5 ml of 20% solution of D-galactose; A plastic cannula is used to prepare the suspension.
Using a cannula, a solution of D-galactose (13.5 ml) is taken and transferred to a vial of granulate, vigorously shaken (for 5 seconds) until a uniform suspension (milky white) is obtained. Use it for the next 5 minutes.
It is impossible to heat the suspension (do not hold vials for a long time!).
In contrast echocardiography in B-mode is administered intravenously bolus, adult 10 ml at a concentration of 300 mg / ml (in tissues with a weak conductivity of sound - 5-8 ml at a concentration of 40 mg / ml, when examining only the right heart - 4-10 ml in a concentration of 300 mg / ml).
Children are administered, depending on their age, 0.5-4 ml at a concentration of 200 or 300 mg / ml; the maximum dose is 6 single-dose injections.
