How to inject test tube babies into the week?
Test tube baby is a kind of fertility method that uses assisted reproductive technology to cultivate fertilized eggs in vitro, and then transplant the fertilized eggs into the uterus to help infertile couples achieve their reproductive aspirations. In the whole process of IVF, weekly injection is a very important part. This article will elaborate on the weekly injection of IVF from the aspects of drug selection, injection method, schedule and common precautions.
Drug selection
The drugs used in the course of weekly injection mainly include ovulation promoting agents and human chorionic gonadotropin (hCG). Ovulation promoting agents are mainly used to stimulate the development of the ovary and make it discharge mature eggs. According to the individual condition, the doctor will determine the appropriate dosage and use time of ovulation promoting agent according to the size and number of follicles.
The purpose of hCG is to stimulate ovulation so that mature eggs can be released normally. Generally, hCG injection is carried out after determining the appropriate follicle size. The dosage and use time of drugs need to be accurately calculated and guided by doctors according to personal conditions.
Injection method
The injection method of weekly injection of test tube babies is generally divided into subcutaneous injection and intramuscular injection. For most drugs, subcutaneous injection is the most common way. Before subcutaneous injection, the required syringes, cotton balls and sterilized alcohol should be prepared. Before injection, wash your hands and ensure the sanitation of tools and environment.
The specific steps of subcutaneous injection are as follows:
1. Clean the injection site: wipe the injection site with sterilized alcohol to ensure cleanliness;
2. Grab the skin at the injection site: pinch the skin with the thumb and forefinger to form a subcutaneous fat fold;
3. Quickly insert the needle into the subcutaneous tissue: insert the needle of the syringe into the skin fat fold, and maintain a uniform and stable speed during injection;
4. Slowly inject drugs: slowly inject the drug solution into the subcutaneous tissue, and keep it stable during the injection process;
5. Pull out the needle: slowly pull out the syringe, and gently press the injection site with a cotton ball to help absorb the liquid medicine.
Timing
The schedule of weekly injection of IVF is mainly determined according to the condition of ovarian ovulation. Before starting the weekly injection, it usually needs a period of observation and examination to determine the condition of the ovary. According to individual conditions, the injection time in the week will also be different.
Generally speaking, the use of ovulation promoting agents generally lasts for 7-12 days, and the specific schedule needs to be determined according to personal conditions. The injection time of hCG is generally within 36 hours after the end of ovulation promoting agent. The doctor will determine the best injection time according to the size and number of follicles.
Common precautions
During the injection of IVF in the week, the following points should be paid special attention to:
1. Pay attention to the storage and use of drugs: drugs should be properly stored and used according to the doctor's instructions to avoid expiration or misuse;
2. Selection and cleaning of injection site: When injecting subcutaneously, select a suitable site for injection and keep the injection site clean;
3. Regular injection: inject drugs on time according to the doctor's instructions to ensure the regularity of drug use;
4. Observe the discomfort reaction: after the injection of drugs, pay attention to observe whether there is any discomfort reaction, such as local redness, swelling, pain, etc., and contact the doctor in time.
To sum up, weekly injection of IVF is an important part of assisted reproductive technology. The correct choice of drugs, the correct injection method, the reasonable arrangement of time and the observance of precautions can ensure the smooth injection process of IVF into the week and provide more possibilities for the realization of fertility aspirations.
