Embryo transfer (ET) is the final and most critical step in assisted reproductive technology. The period from transfer to pregnancy check is the most stressful. People often think, “What should I pay attention to after the transfer? Some suggestions are given for your reference: a. Relax your body after the operation, you can move your body, arms and legs freely; don’t need to hold urine, you can go to urinate if you feel urgent, the embryo will not flow out because of this. Second, regarding rest after transplantation, at present, most of the centers in China advocate bed rest for 10 minutes-2 hours after transplantation, there is no uniform regulation, and there is not enough evidence to show that it is necessary. If there are many people in a large center, the rest time after transplantation is short; if there are few people in a small center, the rest time is relatively longer. Which is better or worse? Results from as early as 1997 suggested that bed rest for 20 min versus 24 h after transplantation had no effect on clinical pregnancy rates, which questioned the need for bed rest after transplantation. A study group of 1091 IVF cycles from 1994-1996 at a UK fertility center, i.e., no rest after ET and activity as usual, and a control group of 19697 IVF cycles from 1994-1995 in the UK national database, i.e., bed rest for a few hours after transplantation, resulted in a significant increase in clinical pregnancy rate in the study group compared to the control group (30% vs. 22.19 % ), suggesting that post-ET bed rest negatively influenced pregnancy outcomes. In a prospective analysis of 692 fresh IVF cycles from another center in China, i.e., patients who walked on their own immediately after transplantation and were discharged with 15 min to 1 h of rest, compared with those who were carted out and stayed in bed rest for 4-6 h after transplantation, the HCG positivity rate in the former was not only unaffected but also significantly higher than in the latter. This shows that there is no correlation between bed rest or not after transplantation on the success rate of IVF. Although there are still few studies on the necessity of bed rest after transplantation, most of them show that prolonged bed rest neither improves clinical pregnancy rate nor reduces early miscarriage rate and ectopic pregnancy rate. We generally recommend appropriate rest for the question of whether patients need rest. Fertility patients have a lot of mental and financial commitment in the IVF process and are understandably worried about implantation failure due to insufficient rest after transplantation. As to how much rest is appropriate, it varies from person to person. It is important not to increase the mental stress and psychological burden. However, bed rest should be avoided. Generally, you can stay away from work for 3 days after transplantation. After that, it depends on individual situation. From the time of transplantation to the time of HCG test to see if you are pregnant, about 14 days, you can go to work as long as you do not overexert yourself. Excessive rest and prolonged bed rest is harmful, and coupled with excessive care from family members, it may cause psychological stress and affect the success rate, and may cause venous embolism in the lower extremities and sudden swelling and pain in the lower extremities. Once this happens, you should see a doctor immediately. Third, the postoperative diet is no different from the usual: a high protein diet and avoiding constipation, diarrhea, allergies, etc. are sufficient. 1, choose easily digestible food and avoid constipation and diarrhea Because of rest and bed rest after in vitro transplantation, so that the amount of exercise is reduced, it is easy to have decreased appetite, indigestion, easy constipation, etc. In order to prevent or reduce constipation and indigestion, it is more important to choose easily digestible food, you can eat more food rich in dietary fiber: for example, celery, cabbage, corn, yam, etc.; help digestion Food: such as rice porridge, soup, etc. In addition, in order to avoid diarrhea, do not drink cold milk and cold drinks, for fear that in case of diarrhea, diarrhea and constipation can cause contractions, which will affect the laying of the baby. 2, high protein diet and attention to dietary hygiene Because of the IVF transplantation before, it is easy to cause ovarian hyperstimulation. These patients initially have abdominal distension and other discomforts, so try to eat high-protein food and have small and frequent meals at this time. If ascites, pleural fluid is found, you can drink winter melon soup, watermelon juice, orange juice, milk, eggs are diuretic to increase protein food. In addition, pay extra attention to the diet, do not eat in small stores without health protection. It is best to choose a clean and tidy environment to eat to prevent diarrhea. 3, forbid to eat food that can easily cause allergies After the IVF transplant, it is also easy to have allergies. This is the time to pay extra attention to not eating foods that can easily cause allergies, such as seafood. In addition, stay away from these allergens to avoid allergies during the transplant process. 4, eat less bite After transplantation, because the patient is more static and less active, eating more fine, coupled with the application of progesterone drugs, mood anxiety, poor sleep, more full feeling, eating should master the principle of eating less bite. 5, easy to contraction and abortion food can not eat activated blood stasis food can not eat, there are dampness detoxification function can not eat food, such as: tonic, sesame oil, watercress, black fungus, cinnamon, coix seed rice. Cigarettes, alcohol, coffee, tea; cold food and fruits should be eaten as little as possible. Four, pay attention to avoid colds, avoid sexual life. V. Injecting hCG, there may be abdominal distension, nausea, vomiting, and in serious cases, even less urination, difficulty in breathing, palpitation, dizziness and dizziness. When the discomfort is more obvious, you should go back to the center for consultation. If special treatment, such as surgery, is performed in the field, it should be reported to our center.
