Pain in the wound after surgery is a normal manifestation, as all wounds have peripheral nerves present, and also after surgery due to the local inflammatory response. In general, nowadays there are several ways to intervene, like the creation of painless wards, in a number of ways: firstly, the surgery is performed in a less invasive way. Secondly, better functional dressings are used to avoid adhesion of the dressing to the wound, which in some cases can compress the wound when it dries out. In addition, a continuous analgesic pump will be used to inject local analgesics at regular intervals, in quantitative, micro-accurate and precise amounts, so that the patient can maintain a pain-free state throughout the process of wound healing, and the wound will grow better and faster in a pain-free and comfortable state.
