  Purpose
Animal and human data have supported the notion that administration of large doses of Vitamin C has beneficial effects on those subjects suffering from large burns. This effect may be due, in part, to the antioxidant and free-radical-scavenging properties of Vitamin C. These studies have demonstrated an improvement in urine output during resuscitation and reduced need for fluid volumes during resuscitation. In turn, these subjects demonstrated a reduction of wound edema, improved respiratory status (demonstrated by improvements in P:F ratios and reduced ventilator days), and no differences in terms of the possible complications of high-dose vitamin C administration between standard and treatment groups. The purpose of this study is to prospectively determine if Vitamin C can be safely used as an adjunctive treatment for patients suffering severe thermal injuries. High-dose vitamin C administered at a dose of 66mg/kg/hr during the acute phase of severe burn injuries will reduce fluid requirements in the first 48 hours after injury.

Primary Outcome Measures:
  • Fluid Volume Requirements during the resuscitative phase after severe burn [ Time Frame: 24 hours ]
    Primary Outcome is to reduce fluid outcome requirements within the first 24 hours after severe thermal injury


Secondary Outcome Measures:
  • Days of Ventilator Support Required [ Time Frame: Hospital Course, estimated 6 weeks ]
    Comparisons between cohorts as to the number of days of ventilator support will be measured

  • Incidence of Abdominal Compartment Syndrome [ Time Frame: Hospital Course, estimated 6 weeks ]
  • Complication and infection rates in the Vitamin C group [ Time Frame: Hospital Course, estimated 6 weeks ]
  • Incidence of Renal Failure [ Time Frame: Hospital Course, estimated 6 weeks ]
    Incidence of renal failure between cohorts will be measured


Estimated Enrollment: 54
Study Start Date: June 2017
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
Victims of severe thermal injury receiving placebo Lactated Ringers solution for the first 24 hours
Drug: Placebo
Lactated Ringers solution will be given at a similar volume to what the treatment group will receive
Other Name: LR
Experimental: Vitamin C
Victims of severe thermal injury receiving high-dose vitamin C 66 mg/kg/hr for the first 24 hours
Drug: Vitamin C
Treatment Group will receive a dose of 66 mg/kg/hr of ascorbic acid injection for 24 hours after injury
Other Name: High Dose Ascorbic Acid

Detailed Description:
Subjects presenting within 6 hours of a severe thermal injury, defined as greater than 20% of their total body surface area, or their family members will be approached on admission to Parkland Memorial Hospital and informed of the study. Those electing to participate in the study will be randomized to receive either high-dose vitamin C (66mg/kg/hr for the first 24 hours, this dosage is based on prior human studies) in addition to the standard resuscitation algorithm (as per the Parkland Formula) or to a control group receiving only the standard resuscitation algorithm. These subjects will then be followed during their hospital course for fluid requirements, urine output, infectious complication rates, liver/renal failure rates, abdominal compartment syndrome rates, and outcomes such as ICU days, total hospital days, and mortality. All adverse events will be monitored by a data safety monitoring board. Currently this is a planned pilot study with a future multi-center study planned based on the results of the pilot. These studies will help determine if high-dose vitamin C can be a safe adjunct to acute fluid resuscitation in severely burned patients.
