Complications and preventive measures of the first generation IVF technology
IVF technology is an important medical technology to provide fertility opportunities for couples who cannot conceive naturally. However, in the first generation of IVF technology, there are some complications that need special attention and prevention. This article will elaborate on the complications and preventive measures of the first generation IVF technology from four aspects: embryo implantation, multiple pregnancy, early abortion and congenital malformation.

Complications of embryo implantation and preventive measures
In the first generation of IVF technology, some complications may occur during embryo implantation. First of all, implantation failure is the most common problem. The reasons include unsuitable endometrium, poor embryo quality, etc. Preventive measures include early assessment of endometrial thickness and morphology, and selection of high-quality embryos for implantation. Secondly, uterine bleeding after implantation is also a common complication. Attention should be paid to avoid excessive stimulation of endometrium, pay attention to rest after operation, reduce activity and avoid strenuous exercise.
In addition, ectopic embryo implantation is also a serious complication. This may cause bleeding or damage to the abdominal cavity, fallopian tubes, etc. Preventive measures include salpingography or ultrasound guidance before implantation to reduce the risk of ectopic implantation. In addition, attention should be paid to the selection of implantation location to reduce the possibility of ectopic implantation.
Complications of multiple pregnancy and preventive measures
In IVF technology, multiple pregnancy is a common complication. Multiple pregnancy increases the risk of pregnancy and fetus. The key to prevent multiple pregnancy is to control the number of embryos implanted. According to the specific conditions of patients, doctors should reasonably determine the number of embryos implanted according to age, egg quality, uterine conditions and other factors. In addition, circular contraceptives or selective embryo freezing can be used to reduce the risk of multiple pregnancies.
For patients with multiple pregnancies, close pregnancy management and regular prenatal examination are required. Follow the doctor's advice, pay attention to balanced diet, avoid strenuous exercise, regularly measure blood pressure and blood sugar, etc., to reduce the occurrence of complications of pregnant women and fetuses.
Complications of early abortion and preventive measures
Early abortion is one of the common complications in IVF technology. The causes of early abortion are complex, which may include poor embryo quality, unsuitable endometrium, abnormal hormone levels, etc. The key to prevent early abortion is to comprehensively assess the etiology of patients, such as screening for chromosomal abnormalities, coagulation function examination, etc. if necessary. At the same time, more detailed assessment and treatment should be carried out for the elderly patients or those who have experienced multiple failures in IVF.
In addition, health care and nursing during pregnancy are also important links to prevent early abortion. It is recommended that patients take more rest to avoid mental and physical overwork. At the same time, we should pay attention to balanced diet, avoid spicy stimulation and food addiction, and increase the intake of vitamins and trace elements.
Complications and preventive measures of congenital malformation
In the first generation of IVF technology, congenital malformation during embryonic development is a serious complication. The key to prevent congenital malformations is to fully evaluate the quality of eggs and sperm, and reasonably select high-quality embryos for implantation. In addition, if the patient is at risk of some potential genetic diseases, such as chromosomal abnormalities, relevant examinations and consultations should be carried out, and normal eggs or sperm should be selected for IVF to reduce the occurrence of congenital malformations.
If pregnant women are found to have abnormalities in prenatal examination during pregnancy, they should be guided to carry out further prenatal diagnosis and examination in a timely manner and formulate corresponding treatment plans. For pregnant women with complications, termination of pregnancy or selective embryo reduction can be selected to reduce the incidence of congenital malformations.
Summary
Although the first generation of IVF technology provides new reproductive options for couples who cannot conceive naturally, there are also some complications. Embryo implantation, multiple pregnancy, early abortion and congenital malformation are common complications. Reasonable selection of high-quality embryos for implantation, control of the number of embryos implanted, comprehensive evaluation of the etiology of patients, pregnancy management and regular prenatal examination are all important measures to prevent these complications. It is believed that the incidence of these complications will be further reduced by strengthening the research and development of technology and the improvement of medical management.
