Abstract
BACKGROUND AND AIMS
In the last years increasing scientific evidence drew attention on the potential effects of anesthetic drugs on postoperative outcome in cancer patients. Local anesthetics, especially lidocaine, have been intensively studied in relation with postoperative outcome in colorectal cancer patients. Our study objectives were to investigate the effects of perioperative intravenous lidocaine infusion on neutrophil-to-lymphocyte ratio and short-term postoperative outcome. Additionally, we also looked at 1 year outcome after intended radical colorectal cancer surgery.
METHODS
150 patients scheduled for colorectal cancer surgery were randomized to receive sevoflurane anaesthesia with or without 48 hours lidocaine infusion.
RESULTS
73 patients were included in the group A (sevoflurane) and 77 in the group B (sevoflurane with lidocaine). Lidocaine infusion did not modify neutrophil-to-lymphocyte ratio at 24 hours after surgery (p=0.58). Patients receiving intravenous lidocaine had significantly lower morphine consumption (p=0.04), faster mobilization time (p=0.001) and fewer days spent in the hospital (p=0.04). Moreover, at 1 year follow- up, patients in group B had a significant decreased rate of recurrences (p=0.03). There was no significant difference in 1 year survival (p=0.22).
CONCLUSIONS
In our study, intravenous lidocaine infusion hastened the postoperative recovery of patients in terms of mobilization, hospital discharge and opioid consumption and reduced 1 year recurrence rate. Further studies on larger groups of patients are needed.
