Most importantly, its elastic and high performance makes it excellent in vascular sutures.

Simply put, the blood in the blood vessels is a peak and valley with fluctuations in volume with blood pressure. When the fluid in the blood vessels is full, it can pull the anastomosis port, which can be stretched like a rubber band and not easily.

The elastic rope is hardly pulled. When the amount of fluid in the blood vessel is at a low point, it retracts well to promote the healing of the opening.

The unique advantage of polypropylene wire is undoubtedly very suitable for the anastomosis of the heart entering and leaving the large blood vessels in the human body's largest blood pump.

For adult heart transplants, it is indeed enough to just use polypropylene thread to suture it.

Pediatrics, it's different.

In pediatrics, pediatric surgeons need to focus on the characteristics of children's growth and development. In pediatric orthopedics, it is the same as in other pediatric surgery. In pediatric cardiac surgery, pediatricians need to worry about the anastomosis of the children's blood vessels again.

On the one hand, we can focus on the advantages of children's vigorous metabolism compared to adults.

Based on comprehensive measurement, doctors can use absorbable sutures in this place to match non-absorbable sutures, giving the child's own human tissue more self-repair fault tolerance space in the anastomosis.

In this operation, the doctor sews a blood vessel anastomosis, and half of it can use non-absorbable sutures and half of it.

How to choose absorbable sutures. Remember that absorbable sutures will be absorbed by the human body. Therefore, what doctors need to do is to ensure that the absorbable sutures are not absorbed by the human body before the wound heals, otherwise, the wound

The thread disappeared before healing, which also means that the suture failed.

There are many kinds of absorbable sutures on the market, some degraded quickly and some degraded slowly. This refers to the time when sutures disappear in the human body. Is it okay to choose slow-degraded sutures for slow-degraded human tissues?

No, some absorbable sutures degrade slowly, but they provide a shorter tension support time, only a few days, which is not as good as degrading fast tension support time for sutures. Therefore, you should pay special attention to choosing this suture.

The human tissue that is sutured needs strong tension support. If necessary, the factor must be considered is to focus on the tension support time.

For example, peritoneal sutures, such as current vascular sutures, all have special requirements for tension support, so this point needs to be considered. For this reason, the absorbable suture commonly used in pediatrics in clinical practice is the PDS line. Since this is the case, this line is placed in

Can adult large blood vessels work? No. Compared with polypropylene wire, it is still a bit worse.

The above just once again shows that medicine is a engineering department.

Doctors choose good suture materials and how to use them well is also a technical question. Whether it is polypropylene thread or PDS thread, the two have a common point, which is too slippery. If it is slippery, it is convenient to pass through human tissues and less damage. The other is

The pain point brought by the aspect is that it is easy to slip out after tying the knot. Use these two lines to tie a knot, tie a knot with other materials, and the doctor needs to tie several knots on them. It is not good to tie too many knots.

In terms of suturing, intermittent suturing is not suitable, and continuous suturing is used.
