Currently the prevalent approach to perioperative management of patients is ERAS (Enhanced Recovery After Surgery) concept. This approach includes numerous aspects, among which the perioperative use of multimodal analgesia takes one of the leading places. Within the ERAS guidelines all sorts of minimization of opioid analgesics use in schemes of postoperative analgesia are appreciated. Thus, new pharmacological approaches are being actively developed currently in order to achieve adequate analgesia and to minimize the use of this group of drugs. One of the most perspective trends within the multimodal analgesia concept is continuous infusion of non-steroidal anti-inflammatory drugs (NSAID). Up to date there are papers that both confirm the effectiveness of this method for maintaining adequate postoperative analgesia and show its limitations and deny the advantages of the continuous use of NSAID. Up to this time the main attention of the medical community was paid for such drugs as paracetamol and ketoprofen. Nevertheless, one of the most common and safe NSAID is ibuprofen. In spite of this, there are no studies that explore the effectiveness of the continuous infusion of this drug. Thus, the lack of even low-quality evidence led to setting up a study of effectiveness and safety of continuous infusion of ibuprofen in comparison to its bolus injection.
