Brief Summary:

Objectives: For major laparoscopic surgery, as with open surgery a multimodal analgesia plan can help control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects.

Methods: We conducted a prospective, randomized, study of 103 patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital.

Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale (NRS) scores and amount of intravenous morphine used via patient controlled infusion.

Arm Intervention/treatment
Experimental: Wound catheter
analgesia with wound catheter after colon surgery
Device: 19Gx500-mm Pajunk InfiltraLong® catheter
Before completing the surgery, the surgical team inserted a 19Gx500-mm Pajunk InfiltraLong® catheter with multiple perforations in the last few centimeters before the tip to allow for local anesthetic administration.

Active Comparator: morphine
analgesia with morphine after colon surgery
Drug: morphine
After the intervention patients had access to intravenous morphine via a patient-controlled analgesia

Primary Outcome Measures :
  1. Assessment of Numerical Rating Pain Scale (NRS) after laparoscopic colon surgery using interfascial continuous wound infiltration [ Time Frame: Over the 48 hours after laparoscopic colon surgery ]
    Numerical Rating Pain Scale was used to measure the after-intervention Pain. This scale is widely used and shows good correlation with the Visual Analogue scale, specifically in the case of elderly individuals. Compared to other scales, it has low error rates and high validity. This score was assessed in all the participants.

  2. Assessment of intravenous morphine consumption after laparoscopic colon surgery [ Time Frame: Over the 48 hours after laparoscopic colon surgery ]
    Intravenous morphine consumption was administrated via patient-controlled analgesia device. The consumption was evaluated in all participants in the study at the following measurement points: at 30 min, 2h, 8h, 24h, and 48h after the intervention.

Secondary Outcome Measures :
  1. Complications related to intravenous morphine consumption [ Time Frame: Over the 48 hours after laparoscopic colon surgery ]
    Complications related to intravenous morphine consumption were measured: nausea, vomiting and pruritus throughout the treatment period. Paralytic ileus awas measured 24h after surgery. This was assessed for all patients. Moreover, especially for patients belonging to the experimental group, potential adverse effects from placement of the wound catheter such as infection or haematoma at the surgical site or potential toxicity of local anesthetic (e.g., tinnitus, obnubilation) were recorded.
