Before the test tube enters the cycle, it is necessary to have a detailed understanding and not blindly follow the trend.
The first thing we need to look at is ovarian hyperstimulation syndrome (OHSS), ovulation induction is required for IVF**. Perhaps every woman who receives ** expects to develop more follicles and hopes to have more embryos to increase the chance of pregnancy. But you know what?More follicles is not always better. With the increase of developing follicles, there may be a common complication of ovarian hyperstimulation syndrome (OHSS), ovarian hyperstimulation syndrome (OHSS), which is one of the main complications of assisted reproductive technology, is the body's overreaction to ovulation induction drugs, the development of multiple follicles in both ovaries, the enlargement of the ovaries, and the increase of capillary permeability, so that a large amount of body fluid and albumin exudes into the third space of the human bodycomplications of a range of clinical symptoms. The incidence of mild to moderate OHSS is 20 to 33 percent, and the incidence of severe OHSS is 2 to 6 percent.
So, what are the classifications of ovarian hyperstimulation syndrome?
Early-onset OHSS: occurs within 9 days of ovulation retrieval or ovulation and is associated with the use of LH or HCG to induce stimulation.
Late-onset OHSS: the occurrence is associated with a flat increase in HC** after pregnancy, and the symptoms are more severe, and it is more likely to occur in patients with an open fetus.
What are the symptoms of OHSS?
1. Rapid weight gain.
2. Ascites: gastrointestinal discomfort, abdominal distention, malignant vomiting and other symptoms.
3. Pleural effusion: chest tightness, difficulty in breathing steadily, and difficulty in lying flat.
4. Oliguria or anuria.
5. Thromboembolism: When venous thrombosis of the lower limbs occurs, it can be manifested as swelling and pain of the lower limbsChest tightness, chest pain, and dyspnea may occur in pulmonary embolism.
6. Abnormal laboratory examination: blood routine showed hemoconcentration, increased white blood cells, electrolyte imbalance, abnormal liver and kidney function, and abnormal coagulation function.
Can I still have a transplant if I have ovarian hyperstimulation syndrome?This problem is a concern for many people, and for patients with polycystic ovary syndrome, who have a tendency to be over-excited, or who have already developed excessive stimulation, the doctor will recommend canceling the fresh embryo transfer and adopting whole embryo freezing. Because of the pregnancy after embryo transfer, the production of endogenous HCG may exacerbate OHSS, resulting in delayed OHSS.
Ovarian hyperstimulation syndrome is certainly dangerous, but as long as we reasonably prevent it, increase vigilance, actively and correctly deal with it, and patients and doctors cooperate with each other and work together, I believe that the vast majority of patients can successfully pass this difficult and dangerous period.
