Brief Summary:

Surgical resection is the best treatment option for colorectal cancer. Despite this radical approach, recurrences within five years are still common. Several authors have proposed that the immunosuppressive state surrounding the perioperative period was a key element of cancer cells spread.

A particular subtype of T lymphocytes, the Natural Killer cells (NKs), is the main actor of the innate immune system. Several factors of the perioperative period can reduce activity of NKs such as stress, pain, opioids and general anaesthetics.

Lidocaine is a local anaesthetic that has been widely used intravenously for abdominal surgeries. Intravenous lidocaine has been shown to reduce pain scores, morphine consumption, ileus time and length of stay in major colorectal surgeries. It reduced markers of systemic inflammation as well.

The authors hypothesize that the use of intravenous lidocaine during laparoscopic surgeries for colorectal cancer resection will preserve NKs activity.

Arm Intervention/treatment
Experimental: Intravenous Lidocaine
Patients undergoing laparoscopic surgery for resection of colorectal cancer will benefit of an infusion of intravenous lidocaine from the induction of anesthesia untill one hour after PACU admission
Drug: Intravenous Lidocaine
Lidocaine infusion: 1.5 mg/kg bolus on 10 minutes (maximum 150 mg) followed by 1.5 mg/kg/h
Other Name: Chlorydrate de Lidocaine 2%

Placebo Comparator: Placebo
Infusion of normal saline form the induction of anaesthesia untill one hour after PACU admission
Drug: Normal saline infusion
Normal saline infusion: 1.5 mg/kg bolus on 10 minutes (maximum 150 mg) followed by 1.5 mg/kg/h

  2. Morphine consumption [ Time Frame: From the PACU to the 3rd day after surgery ]
    Morphine consumption from the PACU to the 3rd day after surgery

  3. Ileus time [ Time Frame: Day 1 and Day 3 after surgery ]
    time to get flattus after surgery

  4. Surgical complications [ Time Frame: Within 3 days after surgery ]
    Infections, leakage, abcess

  5. Fentanyl dose [ Time Frame: Operative time ]
    Cumulative dose of fentanyl needed for the surgery

  6. Nausea and vomiting [ Time Frame: From the PACU to the 3rd day after surgery ]
    Nausea and vomiting from the PACU to the 3rd day after surgery

  7. Major adverses events [ Time Frame: Start of the surgery untill one hour after PACU ad;ission ]
