According to British scientists, about 300 million operations are performed around the world annually. They cause acute postoperative pain, the management of which is crucial for improving patient outcomes and reducing healthcare costs. Local anesthetic infiltration before closing the surgical incision is a commonly used technique in the operating room. This review focuses on the use of local anesthetic infiltration, 0.25% bupivacaine, into surgical incisions to reduce postoperative pain, as confirmed by an estimate of a reduction in the use of postoperative opioids and a visual analogue scale (VAS). The presented clinical cases and the combined analgesia scheme with infiltration of a local anesthetic into the postoperative wound were used to make it possible to argue about the effectiveness of anesthesia because on the peripheral mechanism of pain. Infiltration analgesia reduced the need for opioids and the time of stay in hospitals. It was concluded that there is a need for further research on methods of delivering anesthetics to postoperative wounds for pain management and improving the quality of treatment.
