[Why does the wound cut by the doctor not bleed during the operation]

The skin is very delicate, and if it is accidentally scratched or punctured, the skin will bleed immediately, even continuously. Usually when watching TV, it can be found that the doctor will not bleed when cutting the wound, no matter how big the wound is, a drop of blood cannot flow, which also makes many people wonder how this situation can occur.

Why does the wound cut by the doctor during the operation not bleed?

1. Special scalpel

The scalpel used by doctors is particularly special, the most common is a high-frequency electric knife, which has the effect of coagulating tissue, so when cutting or peeling with a high-frequency electric knife, the amount of bleeding is very small. This type of knife also has a hemostatic effect, and when bleeding is immediately followed by electrocoagulation with a high-frequency electric knife, the bleeding is stopped.

2. Anesthesia

The reason why there is no blood loss during the operation is mainly due to anesthesia technology. Intraspinal anesthesia can block sympathetic fibers, reduce peripheral venous and arterial blood pressure, reduce the amount of blood flowing to the arteries, and minimize venous exudation at the surgical site.

3. Rich hemostasis measures

In the eyes of doctors, the types of bleeding are divided into dozens, the types of bleeding are different, and the hemostasis measures are not the same. Commonly used hemostasis methods are tamponade hemostasis and ligation to stop bleeding, as well as clamping to stop bleeding and compression to stop bleeding, no matter which means can quickly stop bleeding and prevent blood loss.

4. Operation

Some doctors are highly skilled, stable during surgery, accurate and skilled in the surgical level, so as to achieve zero bleeding.

How to do a good job of nursing after surgery?

1. Avoid water from the wound

Whether it is a large wound or a small wound, it is necessary to keep it dry and clean, avoid getting wet, so as not to cause infection caused by bacteria in the water invading the wound, and do not take a bath before removing the stitches.

2. Change the dressing regularly

Generally, the dressing is changed for the first time about 24 to 48 hours after surgery, and then every 3 to 4 days, and the replacement time should be appropriately extended for special parts, such as every 7 to 9 days after skin grafting, and every 3 to 5 days after breast surgery. If there is more wound secretion, it is also necessary to increase the frequency of dressing change to ensure that the excipients are dry and clean.

3. Disinfection must be carried out before dressing change

Disinfect the surrounding wound immediately after uncovering the dressing, if the wound is sterile, it should be slowly scrubbed from the middle to the outside, if the wound is infected, it should be scrubbed from the outside to the middle, and once the foreign body in the wound is found, it should be removed immediately. If the dressing dries and is difficult to uncover, apply saline to moisten it and slowly uncover it.

4. Remove the wire according to the part

Different parts, the stitch removal time is also different. The amount of movement of the limbs is large, generally it takes about 10 to 14 days to remove the stitches, and it takes 14 days around the joints; the head and face blood circulation is abundant, and the stitches can be removed in 3 to 5 days; the skin on the buttocks and lower back is thick, and the stitches can be removed in 7 to 10 days. Those receiving glucocorticoids, diabetes, and obesity have slow wound healing speeds, and when to remove stitches still needs to follow the advice of doctors.

5. Adjust your diet

In order to promote wound healing, do not smoke or drink alcohol after surgery. Eat more foods that contain high-quality protein, such as lean meats, fish, milk and eggs, and legumes, and focus on vitamins and minerals to prevent scarring.

Tips

In fact, from the moment of surgery, the wound has begun to bleed, and the type of operation, the size of the wound and the time of operation determine the amount of bleeding from the operation. General large surgeries such as orthopedic tumors, abdominal and craniotomy and other blood loss is large, which can easily lead to large-scale bleeding. Heavy bleeding is highly life-threatening, so doctors will reduce intraoperative bleeding in these ways. #健康过大年 #
