Clinical Trial Summary

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.

Intervention

Drug:
Intrathecal Morphine
One group of subjects will receive intrathecal morphine: spinal (neuraxial) dose of preservative free morphine (Duramorph), usually about 4-5mcg/kg. This is injected into the cerebrospinal fluid under sterile technique by a pediatric anesthesiologist while the subject is already under general anesthesia. This procedure is well-described in the pediatric population and used regularly for postoperative pain relief for a variety of procedures including ureteral reimplantation.
Quadratus lumborum block
The second group of subjects will have bilateral quadratus lumborum blocks: peripheral nerve block utilizing ropivacaine 0.2%, usually about ½ mL per/ kg per side (total dose approximately 1mL/kg). This is injected in the subject's flank in the fascial plane between the quadratus lumborum muscle and the psoas muscle. Ultrasound guidance is used for needle and structure localization and this procedure is done by a pediatric anesthesiologist while the subject is already under general anesthesia. Quadratus lumborum blocks are regularly used in clinical practice for postoperative pain relief for a variety of abdominal procedures.

Outcome

Type Measure Description Time frame Safety issue
Primary Duration of analgesia The primary endpoint will compare the effect that intrathecal morphine and quadratus lumborum blocks have on the duration of analgesia as demonstrated by charted pain scores and morphine equivalents in the first 24 hours. Up to 24 hours post-op
Secondary Side effects of each intervention The secondary endpoint will assess the side effects of each intervention such as nausea and vomiting, and pruritis. up to 48 hours post-operative
Secondary Patient/Family Satisfaction This endpoint will assess patient and family overall satisfaction with their child's pain control and experience of their child's post-op recovery. Satisfaction will be rated using VAS 0 (not satisfied) to 100 (completely satisfied). up to 48 hours post-operative
Secondary Total Length of PACU and Hospital Stay This endpoint will assess how long the patient's PACU stay was in days, and how long their hospital stay overall was, also in days. time to discharge after surgery, (an expected average length of hospital stay is approximately 2-4 days)
