What are the advantages of using CO2 gas for laparoscopic artificial pneumoperitoneum?

1.Carbon dioxide is an inert gas, which is not easy to cause other chemical reactions, and does not cause more smoke and does not affect the surgical field;

2.If an electric knife is used during surgery, there will be sparks, and if it is oxygen to build pneumoperitoneum, it will cause ** and cause danger;

3.Carbon dioxide is retained in the human body, and the blood solubility is high, and the human body can absorb it. It is easy to exhale through the lungs and is not easy to cause hypercapnia due to excessive absorption; 4.

If you use oxygen or nitrogen, it is not easy to be absorbed in the body, and the gas in the peritoneal cavity is not easy to be discharged after surgery, and there is a risk of gas embolism if the pressure is too high.

The main reason for choosing degenerative gas is that electric knife, ultrasonic knife and other instruments should be used in the cavity to avoid generating a large amount of smoke and affecting the field.

Answer] The purpose of :d artificial pneumoperitoneum is to avoid damage to the abdominal organs and facilitate laparoscopic feeding and observation. The inflatable gas is generally CO2, and the amount of CO2 injected into Huai is about 2000 3000ml, and the lead is used to make the intra-abdominal pressure reach 30mmH2O.

Electrocoagulation is often used to stop bleeding during laparoscopic surgery.

A small amount of electric spark is generated.

There is a risk of oxygen building up pneumoperitoneum.

That's why carbon dioxide is used.

1.Carbon dioxide.

It is an inert gas and is not easy to cause other chemical reactions.

It will not cause more smoke and will not affect the surgical field;

2.If an electric knife is used during surgery, there will be sparks, and if it is oxygen to build pneumoperitoneum, it will cause ** and cause danger;

3.Carbon dioxide is retained in the human body, blood solubility.

The high, the human organism is able to absorb it. Does not cause hypercapnemia; 4.If oxygen is not easily absorbed in the body, it may cause oxygen toxicity.

Electrocoagulation is often used in laparoscopic surgery to stop bleeding, which produces a small amount of electrical sparks, and there is a risk that oxygen builds up pneumoperitoneum, so carbon dioxide is used.

In laparoscopic hand repentance, high pneumoperitoneal pressure can lead to ()aIntra-abdominal hemorrhage.

b.Intra-abdominal infection.

c.Hypercapnia and acidosis.

d.Anastomosis is poor and the mouth is empty.

e.The incision is dehiscence.

Correct answer: Hypercapnia and acidosis.

The site where CO2 is injected into the abdominal cavity to establish pneumoperitoneum is ()aIncision at the lower edge of the umbilical foramen.

b.Incision on the upper edge of the umbilical mum transport hole.

c.Right lower abdomen.

d.Right upper quadrant.

e.Left upper quadrant.

Correct answer: Rapid defeat beam umbilical incision at the lower edge of the hole.
