ITM vs QL for Pediatric Open Lower Abdominal Procedures

Intrathecal Morphine Versus Bilateral Quadratus Lumborum Blocks for Perioperative Analgesia in Pediatric Patients Undergoing Open Lower Abdominal Procedures: A Prospective Randomized Trial

Patients between the ages of 12 months and 11 years who are undergoing an open lower abdominal procedure will be randomized to receive intrathecal morphine, or bilateral quadratus lumborum block. The investigators will compare the effect that intrathecal morphine and quadratus lumborum blocks have on the duration of pain control as demonstrated by charted pain scores and morphine equivalents in the first 48 hours. This study will also assess the side effects of each intervention such as nausea and vomiting, and itching.
