Academic level and innovation of new technology and business of target-controlled infusion in anesthesiology department.

Postoperative trauma will inevitably produce different degrees of pressure and pain to the body.

Pain and pressure are average.

Lasting for several days to several weeks may cause a series of respiratory, circulatory, endocrine and metabolic functions.

Disorder or disorder, thus affecting the surgical effect and postoperative rehabilitation. Block postoperative pain reflex arc to ensure external

The department treats patients with comfortable and painless perioperative period, inhibits the stress reaction and inflammatory reaction caused by surgical trauma, and maintains

Normal organ function is extremely important.

Ok, it has been widely used in clinic since 1990s.

With the rapid development of technology, its defects are gradually increasing.

Exposure, the literature shows that intravenous route.

Cases leading to overdose during this period have also been reported from time to time.

The reason is the pharmacokinetics of analgesic drugs.

There are great differences among individuals, and the pain intensity of patients at different times after operation is also very different.

Relative tolerance

It is easy to cause insufficient analgesia or drug overdose. Target controlled infusion (

) technology

According to the principles of pharmacokinetics and pharmacodynamics, it is controlled by computer with the concentration of plasma or effect room as the index.

In clinic, the depth of anesthesia and analgesia can be adjusted by changing the infusion rate. automation
