What preparations are needed before cesarean section?

In recent years, with the rapid development of medical technology, especially with the development of important fields such as anesthesiology, cesarean section surgery has become very mature. Due to various reasons, such as some pregnant women not meeting the conditions for natural birth, they must undergo a cesarean section. This is a completely different method of delivery from traditional natural birth. So what preparations should pregnant women make before a cesarean section?

What preparations are needed before cesarean section?

Preparation 1: Blood type test

Implementation method:

When the pregnant mother is admitted to the hospital and before the operation, venous blood will be drawn and the blood type will be tested in the laboratory.

reason:

Blood typing is helpful for timely cross-matching of blood during surgery and rescue of hemorrhagic shock. The pregnancy lasts for 40 weeks, during which various complications may occur: incomplete miscarriage in early pregnancy, placenta previa and early placental abruption in late pregnancy, and excessive uterine bleeding caused by uterine atony or abnormal placental abruption after delivery, all of which may put the pregnant mother into a state of shock. Timely blood matching and transfusion are very important for rescue work, and every second counts and is the key to success. For example, it is very difficult to obtain blood from people with Rh negative factors, and we need to know about it early so that we can make emergency blood preparations in advance.

It is convenient to detect blood type incompatibility between mother and baby in time. If a pregnant mother with type O blood is married with type A, B or AB blood, or if the pregnant mother is Rh negative and her spouse is Rh positive, mother-fetal blood type incompatibility and neonatal hemolytic disease may occur. Knowing it early will help us monitor and treat neonatal hemolytic disease and reduce harm to the baby.

What pregnant mothers need to do:

If you have a history of blood transfusion or pregnancy, be sure to tell your doctor.

Remember your blood type. If you don't know or have any questions, ask your doctor immediately.

If a blood transfusion is required, ask the recipient's blood type during the transfusion to see if it matches the recorded blood type.

Preparation 2: Catheterization

Implementation method:

Two or three hours before going to the operating room, the nurse will disinfect the pregnant mother's perineum and then insert a thin sterile catheter into the urethra into the bladder to drain the urine. The catheter is fixed to the surgical gown with tape and connected to a urine bag at the end.

reason:

Cesarean section is performed in the pelvic cavity, and the bladder is located in front of the uterus. When the bladder is full, it may affect the exposure of the surgical field of view and may easily cause accidental injury during the operation. Therefore, an indwelling catheter needs to be placed before the operation to empty the bladder.

In addition, the placement of a urinary catheter is also to prevent the relaxation of the urethral sphincter of the pregnant mother after anesthesia, causing urinary incontinence or inconvenience of urination after surgery. It is also convenient for monitoring urine output after surgery.

What pregnant mothers need to do:

When pregnant mothers change their lying positions, they should always consider the position of the catheter and be careful not to compress or twist the catheter.

If the urine bag is half full, it should be drained out immediately. There is a small switch at the bottom of the urine bag, and the urine will flow out when it is pulled out. There is also the milliliter number on the urine bag, pregnant mothers should write it down.

Generally, the indwelling urinary catheter can be removed after the infusion is completed on the second day after the operation, and urination should be timely 3-4 hours after removal. Try not to urinate in bed, and drink plenty of water to promote urination to avoid urinary tract infection. If you cannot urinate, tell your doctor until you can urinate freely.

Preparation 3: Fasting Water

Implementation method:

No matter how much the pregnant mother could eat before, she must fast and not drink water 8 hours before the cesarean section. For example, if the pregnant mother has the surgery in the morning, she cannot eat or drink water from 12 o'clock the night before. If the surgery is in the afternoon, she cannot eat lunch.

reason:

Gastrointestinal preparation is an important part of preoperative preparation, which is mainly to prevent vomiting during anesthesia or surgery, causing suffocation or aspiration pneumonia. This vomiting reaction may occur at any time during the anesthesia process. If the pregnant mother undergoes anesthesia surgery after eating or drinking a lot of water, the food in the stomach may be vomited out before it is digested. This will not only affect the normal progress of the operation, but may also cause serious complications.

What pregnant mothers need to do:

Listen to the doctor, don’t “sneak” food, and endure it even if you are hungry.

Eat what you want for the last meal before surgery so that you can feel satisfied with the food and not feel too wronged.

If you have dentures, remove them as well.

If you have dry mouth, you can relieve it by gargling or moistening your lips with a cotton swab dipped in water.
