Everyone has at least general medical knowledge and experience.
Stitching is a skill that should not be tried for the first time. For minor lacerations, you do not need to obtain a medical license to put on decent stitches. Many nurses and medical staff possess this skill. There are many online guides and it is easy to practice. If you have just learned to suture wounds but cannot afford silicone pads, you can sew an orange and then pick up a large bag of butcher’s pig feet to hone your skills. Some people say that chicken skin is very suitable for practice, which is better than real skin. It is fragile, but it can be stitched well, and it is found to be better than pig skin. You only need to buy chicken drumsticks at the grocery store. But their disadvantage is that they are easy to rot and are not as durable as silicone suture pads. Good quality silicone suture pads can be used 100 times.
With good practice, you should be able to suture wounds that will not cause arterial bleeding or body cavity, neck or face injuries. For those severe patients, it is best to rely on bandaging the wound and applying pressure until professional medical help is found.
As a medical student, the most difficult part of suturing is learning how to tie a knot, not a needle (if there is no human tissue, this is difficult to practice. Even pig tissue cannot imitate it well). You can practice with a string of thick lines. Just wrap them around the armrests of tables and chairs. Then, you can sit in a chair and watch TV, and you can do one-handed or two-handed knotting exercises over and over again, and the whole process is full of fun. You are trying to build muscle memory, so after a while you can unconsciously repeat the knot endlessly.
