Обзор
There are very few data in the literature on changes in inflammatory markers when lidocaine is administered perioperatively in patients with colorectal cancer. In patients undergoing surgery for colon cancer, the aim is to conduct a double-blind placebo-controlled study to determine differences in levels of pro-inflammatory markers, postoperative pain and opioid analgesic consumption in the first two days after surgery, and the time to first postoperative bowel movement. Groups of patients receiving perioperative lidocaine infusion, high dose dexamethasone or placebo will be compared.
Подробное описание
In 80% of cancer patients, surgery is indicated during treatment. The choice of anasthetic technique can indirectly influence the patient's inflammatory and immune systems. Although a large body of data on the association between surgical stress and anasthesia in in vitro tumor models is already available, the importance of the individual drugs used during anasthesia on the inflammatory response and the post-operative course of patients is not yet fully understood, and further research is needed in this area.
There is increasing evidence that perioperative intravenous infusion of lidocaine has analgesic, prokinetic and anti-inflammatory properties in patients treated with surgical procedures. A significant number of studies have confirmed the positive effects of intravenous lidocaine infusion on reducing postoperative pain and reducing perioperative opioid consumption. In recent years, a growing number of studies have investigated the positive effects of lidocaine infusion on promoting peristalsis and faster recovery after surgery and on reducing the perioperative inflammatory response. This effect is also beneficial after colon surgery.
Inflammation is particularly detrimental in cancer patients as it may be associated with more frequent postoperative complications, slower recovery, and poorer cancer outcome (recurrence and/or survival), irrespective of the incidence of perioperative complications.
Surgical stress may promote tumor sequelae in several ways: ischemia and reperfusion injury, sympathetic nervous system activation, inflammation, systemic hypercoagulable state, immune suppression and the effects of anesthetics.
Proinflammatory markers, postoperative pain, opioid consumption, time to first postoperative bowel movement, and the effect on postoperative course in groups of patients receiving perioperative infusion of lidocaine or placebo have not yet been investigated in a double-blind placebo-controlled study. The data generated in this study may represent an important scientific contribution with a positive impact on the management of patients undergoing surgery for colon cancer.
