How many days can sodium chloride be administered for fetal protection

The use time of sodium chloride injection in fetal protection treatment usually does not exceed 7 days, and it needs to be adjusted according to the individual situation of the pregnant woman, medical advice, and fetal status. Sodium chloride injection is mainly used to maintain fluid balance or as a drug diluent. Long term intravenous infusion may increase the risk of edema or electrolyte imbalance. For the treatment of threatened miscarriage or high-risk pregnancy, sodium chloride injection is often used as a carrier for other contraceptive drugs. Short term infusion can help stabilize the blood circulation of pregnant women, but it needs to be combined with core fetal protection drugs such as progesterone and magnesium sulfate. Doctors will dynamically evaluate based on indicators such as cervical length, frequency of contractions, and progesterone levels. In most cases, basic treatment goals can be achieved within 3-5 days. When pregnant women have special conditions such as gestational hypertension and renal dysfunction, it is necessary to strictly control the infusion time of sodium chloride. In such cases, it may be necessary to shorten it to 2-3 days and replace it with glucose solution. In a very small number of cases where prolonged infusion is required due to severe dehydration or massive bleeding, the plan must be adjusted through 24-hour monitoring of urinary protein, blood sodium concentration, and other factors. During the period of fetal protection, in addition to following medical advice for treatment, pregnant women should stay in bed and avoid lifting heavy objects or engaging in strenuous activities. Diet should ensure high-quality protein and dietary fiber intake, such as eggs, fish, broccoli, etc. The daily water intake should be controlled at 1500-2000 milliliters. Regularly monitor fetal heart rate and undergo B-ultrasound examination. If there is headache, blurred vision, or abnormal uterine contractions, seek medical attention immediately. The adjustment of contraceptive drugs must be determined by obstetricians based on clinical indications, and the dosage cannot be increased or decreased or the course of treatment cannot be extended on their own.
