Uterine infusion is a procedure that involves direct administration of a substance, fluid, nutrient or a drug directly into the uterus of a female. This is usually carried out by means of gravitation force when the infusion is held way above the position of the patient. During this procedure it is obligation to maintain sterilization and ensure that the procedure is carried out in aseptic conditions. The equipment must be checked before, during and after the infusion process to make sure that it is functioning properly without any mechanical difficulty. Presence of an expert physician or preferably a gynecologist is mandatory when an intrauterine infusion is being carried out.
Just like infusion in any other part of the body, intrauterine infusion is also susceptible to incidence of allergic reaction. So, the general and local signs must be monitored through out the procedure and any cardiac or respiratory difficulties must be tended to promptly.

- Infusion drug or substances
- Disposable syringes
- Infusion tubing
- Sterilized napkins

- A few milliliter of normal saline might be injected through the catheter a slow rate to check the presence of catheter inside the uterine cavity.
- It is recommended to administer a small quantity of drug at first as a test dose to minimize the chances of any acute allergic reaction.
- At first the rate of infusion is kept slow that can be increased later on when it becomes evident that patient is not likely to have any hypersensitivity to the drug.
- Advise the patient to avoid changing posture abruptly and ensure that the drug container is always at least 3 feet above the level of patient.
