Recently intraperitoneal nebulization of local anesthetic has been used as an alternative to direct intraperitoneal instillation. Intraperitoneal aerosolization of Bupivacaine 50 mg after laparoscopic cholecystectomy significantly reduced postoperative pain, morphine consumption and incidence of postoperative nausea and vomiting and it is associated with rapid mobilization compared with patients receiving direct instillation of Bupivacaine 50 mg or placebo.
In a recent study the investigators found that nebulization of Ropivacaine 30 mg with the AeronebPro® before or after laparoscopic cholecystectomy and gynecologic laparoscopic surgery reduces postoperative pain and morphine consumption. Patients receiving preoperative nebulization of Ropivacaine presented significantly less postoperative pain (-50% clinical setting) and consumed significant less morphine (-50% and -40% respectively) than patients in control groups during the first 48 hours after surgery.
The effects of peritoneal nebulization of ropivacaine during laparoscopic colectomy on pain control and morphine consumption were not evaluated.
The investigators hypothesize that intraperitoneal nebulization of Ropivacaine may produce better pain control and less morphine consumption than nebulization of saline after laparoscopic colectomy.

- Postoperative pain [ Time Frame: 72 hours ]Numeric Ranking Scale (NRS 0 to 10 points) at rest (static NRS) and after a deep inspiration or cough (dynamic NRS) in PACU and at 6, 24, 48 and 72 hours after the discharge from PACU.
- Time of unassisted walking [ Time Frame: 72 hours ]Unassisted walking time is defined as the time in hours between PACU discharge and when the patient is able to walk out of his room and back to bed without any assistance.
- Return to active bowel function [ Time Frame: 72 hours ]The return of bowel function will be assessed using two parameters: time of first flatus and time of first bowel movement.
- Hospital morbidity [ Time Frame: 72 hours ]All complications or adverse effects associated or possibly associated with the interventions under study, surgery or anesthesia will be quantified
- Time and condition for hospital discharge [ Time Frame: 72 hours ]Time in days elapsed between surgery and hospital discharge.
- Analgesic consumption [ Time Frame: 72 hours ]The total dose of morphine will be quantified using the PACU clinical chart and/or PCA infusers memory display
