Effect of Quadratus Lumborum Block on Pain and Stress Response after Video Laparoscopic Surgeries: A Randomized Clinical Trial.

Background: There are many surgical and anesthetic factors that affect pain and the endocrine-metabolic response to trauma. The ability of anesthetic agents and neuronal blockade to modify the response to surgical trauma has been widely studied in the last few years.

Objective: To evaluate if the anterior quadratus lumborum block contributes to improved surgical recovery, using as parameters analgesia, pulmonary function and neuroendocrine response to trauma.

Outcome of Ultrasound Guided Anterior Quadratus Lumborum Block After Video Laparoscopic Cholecystectomies: A Prospective Randomized Clinical Trial.

Background: Laparoscopy revolutionizing digital and robotic technology for surgical practice. The ability of anesthetic agents and neuronal blockade to modify the response to surgical trauma has been widely studied in the last few years.

Objectives: evaluate if Anterior Quadratus Lumborum Block contributes to attenuate surgical repercussions, having as primary parameters analgesia and secondary the pulmonary function and neuroendocrine response to trauma.
