Postoperative Pain in Adult Patients.

Each surgical intervention associated with even a minor tissue injury is a source of pain which needs to be effectively controlled. Although the Polish national guidelines for post-operative pain management have been published, many patients experience moderate and severe pain in the postoperative period. The aim of this study is (1) to assess pain severity among adult patients after different types of surgeries; (2) to identify demographic and clinical factors associated with postoperative pain.
