Chromic catgut suture is a type of absorbable surgical suture that has been used in surgery for over a century. It is made from the submucosa layer of sheep or cow intestines that undergoes various manufacturing processes to increase its strength, flexibility as well as absorption time in tissues. While chromic catgut suture remains commonly used in surgery today, there are some misunderstandings about its properties and appropriate uses. In this blog post, we will address 5 common myths and misconceptions about chromic catgut suture manufacturer to provide accurate information for surgical professionals.
Myth 1: Catgut sutures harbour more bacteria than synthetic sutures
Many people believe that because catgut suture is made from animal tissue, it harbours more bacteria as well as increases infection risk compared to synthetic absorbable sutures. However, this is a myth not supported by scientific evidence. Multiple studies have shown no significant difference in postoperative infection rates when using catgut versus synthetic absorbable sutures in clean surgical procedures. Proper handling and sterile technique are more important factors in reducing contamination. As long as catgut sutures are processed and sterilized appropriately, they present minimal infection risk.
Myth 2: Catgut sutures should not be used in contaminated or dirty wounds
There is a common belief that catgut suture should be avoided in contaminated or dirty surgical wounds because it will increase infection risk as well as impair healing. However, research shows that chromic catgut can be safely used in clean-contaminated wounds with acceptable results. In fact, some studies demonstrate catgut may elicit less tissue reaction and provide better wound strength compared to synthetic sutures in contaminated settings. With appropriate wound irrigation and antibiotic coverage, catgut remains a reasonable option for deeper suture layers, even in clean-contaminated and dirty wounds.
Myth 3: Chromic catgut lasts longer than plain catgut
It is commonly stated that chromic catgut retains its strength longer and is absorbed more slowly than plain catgut suture. However, scientific evidence does not strongly support this belief. Multiple studies show no significant difference in absorption rates or wound strength retention between plain and chromic catgut at most timepoints. While manufacturing techniques can prolong catgut absorption slightly, the impact of chromic processing is modest and does not provide markedly longer strength retention compared to plain catgut in most tissues.
Myth 4: Catgut sutures should not be used in ophthalmic surgery
Many ophthalmologists believe that catgut suture should not be used in ophthalmic surgery procedures, particularly corneal laceration repair. The concern is that catgut will induce more astigmatism or corneal scarring. However, studies show that chromic catgut performs similarly to synthetic absorbable sutures like polyglactin in corneal laceration repair. There is no evidence that catgut is associated with higher astigmatism or poorer wound healing. Chromic catgut remains an appropriate choice for ophthalmic surgery suturing with good closure strength.
Myth 5: Catgut sutures are highly reactive and inflammatory
A long-standing perception exists that catgut elicits significant tissue reactivity and inflammation. However, scientific evidence suggests catgut does not produce higher inflammatory reactions compared to other absorbable sutures. In fact, some studies show catgut induces less histological reaction than synthetic sutures such as polyglycolic acid. Chromic catgut sutures exhibit excellent biocompatibility with minimal tissue response when used correctly in clinical settings.
Conclusion
While chromic catgut suture has been used for many decades, there are still several common misconceptions regarding its properties and appropriate usage. As discussed above, scientific evidence disputes many of the traditional myths about potential risks with catgut. When handled and placed properly, chromic catgut suture Exporter remains a suitable absorbable suture material for a wide variety of surgical procedures and wound types. Surgical professionals should make suturing material choices based on the latest clinical research and avoid perpetuating unfounded myths about catgut suture.
