The most common problem of any surgical intervention is postoperative pain, which requires appropriate analgesia. The differential responses to the tissue injury during incision are often influenced by many variables including global (i.e. age, personality, gender, surgical approach, genetic, preexisting pain syndrome) and specific (i.e. anxiety, anger, fear, depression, psychological factors). Pain is a complex process for the patient and the Anaesthesiologist who are tasked with managing it. Four processes cause pain perception: Transduction, transmission, modulation, and perception. Postoperative pain is related to many factors, including the amount of soft tissue injury, resulting inflammation, and rib injury as in the case of a thoracic surgical procedure.
