About this study

Official title: Post Operative Analgesia After Pediatric Hip Surgery - PCA, Epidural or Lumbar Plexus Catheter: A Prospective Randomized Control Trial

Hip surgery in children is painful and the optimal modality for managing post-operative pain has not been established. This prospective randomized controlled trail compares lumbar plexus catheter (LPC), lumbar epidural catheter (LEC) and continuous patient-controlled analgesia (PCA) with intravenous morphine.

Read the detailed description

Approximately 1 in 1,000 children born in the US have hip dislocation and 10 in 1,000 have hip subluxation requiring surgical intervention. Pain after major hip surgery in children is severe, yet there is no agreement on the most effective method for pain control. Post-operative pain modalities including lumbar epidural catheters (LEC), lumbar plexus catheters (LPC) and intravenous patient controlled analgesia (IV-PCA) have been described. IV-PCA has historically been the standard of care in spite of its numerous associated side effects. Regional anesthesia modalities have gained popularity because of superior pain control with lower opioid requirements.

In this study, the investigators describe the first prospective randomized controlled trial comparing lumbar plexus catheter to alternatives for post-operative pain management in children after major hip surgery. The investigators hypothesized that LPC would be as safe and efficacious as LEC and IV-PCA with the added advantage of a decreased length of stay. The investigators primary aim was to compare hospital length of stay. Secondary aim was to compare pain scores, opioid consumption and opioid-related side effects.

Being tested
Lumbar Plexus Catheter, Lumbar Epidural Catheter, Patient Controlled Analgesia, Fentanyl, Morphine

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lumbar Plexus CatheterProcedure or surgery

    Also called LPC

    lumbar plexus catheter placed intraoperatively for perioperative pain control

  • Lumbar Epidural CatheterProcedure or surgery

    Also called LEC

    lumbar epidural catheter placed intraoperatively for perioperative pain control

  • Patient Controlled AnalgesiaProcedure or surgery

    Also called PCA

    Patient Controlled Analgesia (PCA) was started post operatively for perioperative pain control

  • FentanylDrug

    Intravenous fentanyl was administered in the operating room for induction of anesthesia. Subsequent doses in the operating room were standardized to be given only for heart rate or blood pressure increases > 20% above baseline and occurring more than 30 minutes after the block if applicable.

  • MorphineDrug

    In the operating room patients, intravenous morphine was administered if patients had a failed block and standardized to be given only for heart rate or blood pressure increases > 20% above baseline and after fentanyl had been administered. Intravenous Morphine was also administered in the operating room if the patient was randomized to the Patient Controlled Analgesia (PCA) arm of the study. Post operatively intravenous Morphine was administered as needed for severe pain.

  • LorazepamDrug

    Also called Ativan

    Intravenous Lorazepam was administered as needed for muscle spasm post operatively.

  • OndansetronDrug

    Also called Zofran

    Intravenous Ondansetron was administered as needed for nausea and vomiting post operatively.

  • DiphenhydramineDrug

    Also called Benadryl

    Intravenous Diphenhydramine was administered as needed for itching postoperatively.

  • AcetaminophenDrug

    Also called Tylenol

    Oral Acetaminophen was administered as needed for pain in the Post-Anesthesia Care Unit (PACU) and then scheduled for 72 hours.

  • OxycodoneDrug

    Oral Oxycodone was administered as needed for breakthrough pain post operatively.

  • RopivacaineDrug

    Intravenous Ropivacaine was administered as part of the initial bolus after placement of the lumbar epidural or lumbar plexus catheter and then as a continuous infusion post operatively.

Study groups in NCT03435692
Study groupRoleWhat they receive
Lumbar Plexus CatheterExperimentalChildren undergoing pediatric hip surgery will have a lumbar plexus catheter placed (with bolus and continuous infusion of ropivacaine) intraoperatively for perioperative pain control. An intraoperative pain protocol will dictate if the patient will receive intravenous fentanyl or morphine. Post operative side effects will be controlled with the administration of ondansetron for nausea and vomiting, diphenhydramine for itching, and lorazepam for muscle spasms. Post operative pain control will be managed with as needed (PRN) morphine and oxycodone as well as scheduled acetaminophen.
Receives: Procedure: Lumbar Plexus Catheter; Drug: Fentanyl; Drug: Morphine; Drug: Lorazepam; Drug: Ondansetron; Drug: Diphenhydramine; Drug: Acetaminophen; Drug: Oxycodone; Drug: Ropivacaine
Lumbar Epidural CatheterActive comparatorChildren undergoing pediatric hip surgery will have an epidural catheter placed (with bolus and continuous infusion of ropivacaine) intraoperatively for perioperative pain control. An intraoperative pain protocol will dictate if the patient will receive intravenous fentanyl or morphine. Post operative side effects will be controlled with the administration of ondansetron for nausea and vomiting, diphenhydramine for itching, and lorazepam for muscle spasms. Post operative pain control will be managed with as needed (PRN) morphine and oxycodone as well as scheduled acetaminophen.

Patient Controlled AnalgesiaActive comparatorChildren undergoing pediatric hip surgery will have patient controlled analgesia (with morphine) started in the post anesthesia care unit for post operative pain control. An intraoperative pain protocol will dictate if the patient will receive intravenous fentanyl or morphine. Post operative side effects will be controlled with the administration of ondansetron for nausea and vomiting, diphenhydramine for itching, and lorazepam for muscle spasms. Post operative pain control will be managed with as needed (PRN) morphine and oxycodone as well as scheduled acetaminophen.
