Pain after abdominal surgery can be extensive. Pain control is an important component of
patient comfort and participation in rehabilitation. Multimodal analgesia methods have shown
to reduce postoperative pain, and have been addressed to be a crucial part of the Enhanced
Recovery after Surgery (ERAS) protocols.
Quadratus lumborum block (QLB) is a posterior abdominal wall block which analgesic efficacy
has been shown for abdominal surgeries, and also for different laparoscopic procedures, such
as ovarian surgery.
The aim of this study is to assess QLB's analgesic efficacy for laparoscopic colectomy
surgeries, using serial pain score assessments and overall opioid consumption; its effect on
patient satisfaction; and its effect on the development of postoperative respiratory
complications. This study is a prospective clinical trial assessing the effect of application
of QLB as a regional analgesic technique for primary laparoscopic colectomy, in comparison to
a historical retrospective cohort.
