Postoperative Pain Assessment in Patients Undergoing Scheduled Laparoscopic Intestinal Resection Surgery

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.
