Conditions
Brief summary
This observational prospective study aims to evaluate the postoperative analgesic effect of a regional anesthesia thechnique (TAP block) in patients undergoing scheduled laparoscopic intestinal resection for intestinal cancer. ASA I-III patients operated between May 1 and September 30, 2019 under general anesthesia according to usual clinical practice, will be included. Patients who meet any of the following criteria will be excluded from this study: under 18 years old, language barrier, cognitive impairment or inability to assist in clinical assessment, drug or alcohol abuse, intake of opioids, consumption of analgesics 24 hours before surgery, BMI \<18 or \>35 kg/m2. Subsequently, an analysis will be made evaluating the quality of analgesia and the appearance of postoperative chronic pain and comparing the patients who underwent TAP block with those who did not.
Detailed description
The transverse abdominal plane (TAP) block is a regional anesthesia technique that blocks the afferent nerves of the anterolateral abdominal wall. This observational prospective study aims to evaluate the postoperative analgesic effect in patients undergoing laparoscopic intestinal resection. ASA I-III patients operated on a scheduled basis, between May 1 and September 30, 2019, by laparoscopy for intestinal cancer resection under general anesthesia according to usual clinical practice, will be included. Patients who meet any of the following criteria will be excluded from this study: under 18 years old, language barrier, cognitive impairment or inability to assist in clinical assessment, drug or alcohol abuse, intake of opioids, consumption of analgesics 24 hours before surgery, BMI \<18 or \>35 kg/m2. Subsequently, an analysis will be made evaluating the quality of analgesia and the appearance of postoperative chronic pain and comparing the patients who underwent TAP block with those who did not.
Interventions
PROCEDURETAP
The transverse abdominal plane (TAP) block is a regional anesthesia technique performed using ultrasound that blocks the afferent nerves of the anterolateral abdominal wall, injecting local anesthetic in the fascial plane between the deep oblique and the transversus abdominis muscles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative acute pain assessed using Visual Analogue Scale, from 0 to 10 | from the arrival to the postanesthesia care unit to the 4 postoperative hours | assessed using visual analogue scale |
| Intraoperative analgesic consumption | from the anesthesia induction to the end of the surgery | assessed measuring the perioperative analgesics provided during the intraoperative period following routine clinical practice |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative chronic pain assessed using Visual Analogue Scale, from 0 to 10 | 2 years postoperatively | assessed using visual analogue scale |
| Side effects | from the arrival to the postanesthesia care unit to the hospital discharge (7 days postoperatively) | to record the perioperative side effects secondary to the analgesia administered perioperatively |
