The purpose of this study is to examine the efficacy of the use of Marcaine in femoral nerve blocks and hematoma blocks for post operative pain relief for femoral shaft fractures in a pediatric population.

Primary Outcome Measures:
  • post-operative pain scores [ Time Frame: with in the first 24 hours ] [ Designated as safety issue: No ]
    We will be looking at post-operative pain scores to see if those in the intervention group have lower pains scores.

  • post-operative narcotic use [ Time Frame: within first 24 horus ] [ Designated as safety issue: No ]
    We will be looking at the amount of narcotics used after surgery to see if there is a reduction in narcotic use

Secondary Outcome Measures:
  • femur fracture healing [ Time Frame: first year ] [ Designated as safety issue: No ]
    we will following patients to look at fracture healing post-operatively

Estimated Enrollment: 180
Study Start Date: February 2011
Estimated Study Completion Date: February 2016
Estimated Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: PCA only
this group will only get a pain control anesthesia pump to use for post-operative pain
Experimental: PCA and femoral nerve block
this group will be receiving a femoral nerve block during surgery and have a PCA post-operatively
Drug: Marcaine
0.75 cc/kg of 1/4% Marcaine
Other Name: bupivacaine
Experimental: PCA + hematoma block
patient will receive hematoma block during surgery
Drug: Marcaine
0.75 cc/kg of 1/4% Marcaine
Other Name: bupivacaine

Detailed Description:

Children with femur fractures can have severe pain after elastic nail fixation. The current national standard for post operative pain control would be intravenous narcotics. In addition to the use of intravenous narcotics, there are two alternative methods used during the surgery in order to potentially decrease the pain post-operatively. These methods are hematoma block or a femoral nerve block. Both are proven safe and effective in children, however little research has been done to look at the effectiveness of these various methods compared to one another.
