This study evaluates the effect of a femoral nerve block on opioid requirements following femoral fracture fixation with flexible nails in the paediatric population. This is a double blind, prospective randomized clinical trial.

Condition Intervention Phase
Pain, Postoperative Procedure: Administration of a femoral nerve block (bupivacaine HCL) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: The Effect of Femoral Nerve Block on Opioid Requirements Following Femoral Fracture Fixation With Flexible Nails in the Paediatric Population: A Double Blind, Prospective Randomized Clinical Trial

Further study details as provided by University of British Columbia:

Primary Outcome Measures:
  • Postoperative morphine requirement; the average 8 hour morphine requirement (mcg/kg/hr) will be recorded [ Time Frame: until patient discharge ]

Secondary Outcome Measures:
  • Pain rating [ Time Frame: immediately post-op ]
  • Sedation/pruritis/nausea/vomiting/urinary retention/respiratory rate [ Time Frame: every 8 hours ]
  • Time to discharge [ Time Frame: from end of surgery ]
  • Time (hours) from end of surgery to sitting on bed with legs hanging over the side [ Time Frame: Unspecified ]

Enrollment: 25
