I remember that for a while, I don’t know where it started, but there was an evil trend in clinical practice. Some patients were so afraid of sutures that they insisted on telling the doctor before any major or major surgery that they must give me good sutures so that they can be able to perform surgery.
It is absorbed by the human body. These people are afraid of leaving foreign objects in their bodies. I don’t know where they heard rumors that if these sutures are left in the body, people will die.
I also know that this statement is impossible. Absorbable sutures were invented later. According to this statement, wouldn't it be true that all previous surgical patients were killed by non-absorbable sutures?
When considering what kind of suture to use in medicine, the first step that doctors have to consider is not whether the suture can be absorbed by the human body, but the tensile strength of the suture material.
As for the tension of human tissue, we have said it since the first surgery with a retractor. After anesthesia, as long as the living tissue is moving, there will always be contraction tension.
In medicine, sutures are used to sew wounds. The purpose is to pull the two ends of the opening together to allow the wound to heal. If the tension of the suture is not strong enough, it will not be able to resist the contraction tension of human tissue. In this way, the human tissue on both sides of the anastomosis will
When contracting repeatedly, this tension can easily break the thread, causing the wound to re-open, causing the suture to fail.
How terrible is a failed suture? If the opening is reopened, isn't it going to cause massive bleeding? Or is it leaking? The wound never heals, anastomotic leakage, repeated infections, and systemic sepsis are really going to kill people - what can the doctor think in his mind?
It's all about these more terrifying things.
Some patients are afraid of the rumor that if sutures are left in the body, they will die. If it refers to suture infection, all sutures now have been strictly sterilized, and the incidence rate is too low. Moreover, if the sutures are not absorbable, there is a risk of infection.
There are also absorbable sutures. Absorbable sutures are not absorbed by the human body immediately as soon as they are sewed. It is meaningless to suture. You have to wait for the wound to grow well before being absorbed by the human body. This process can take as short as a few days.
More than a month.
What these patients are actually afraid of is the rejection reaction of the sutures. The problem is that current medical technology has already developed to the point where various surgical materials have strict usage regulations. Which ones cannot be left in and which ones can be left in the human body for a long time are clearly marked. What can be left in the body?
All materials in the human body must be tested for compatibility with human tissue, and can be used clinically only after passing the review. This has been discussed in orthopedic materials science. Complex materials in orthopedics can do this, even with small seams.
The line has long since crossed this threshold.
At this point, it can be seen that these people's concerns are nonsense.
Indeed, it can be seen in clinical practice that some doctors will ask patients whether to use absorbable sutures before surgery. Where are these sutures that can be selected by the patient generally used? The innocuous layer of skin that has little to do with the patient's life. After all, there are some
The patient's financial constraints were limited and he could only pay for medical expenses. At that time, the absorbable sutures were called cosmetic sutures, which were very expensive and had to be paid for out of pocket.
The choice of sutures is a matter of concern for the patient's life. It is impossible for doctors to leave this professional thing to patients who do not understand medicine to make random choices. That is equivalent to handing a knife to someone to commit suicide.
Speaking of polypropylene threads, the most commonly used place is in blood vessels.
The advantages of single-strand threads of this material are that they are less susceptible to infection than multi-strand threads. Their smooth properties allow them to cause less damage when passing through human tissue, and they have low rejection reactions when left in the human body for a long time.
