Outcomes
Primary outcome [1] 259036 0
The primary objective is to determine if adding high-dose intravenous antioxidant therapy (sodium ascorbate) to standard therapy will reduce a patient?s inflammatory conditions using max C-reactive protein (CRP) as the surrogate marker. A blood sample will taken at baseline and then daily to obtain the Max CRP value.
Timepoint [1] 259036 0
5 days' following admission to the hospital.
Primary outcome [2] 259037 0
The primary objective is to determine if adding high-dose intravenous antioxidant therapy (sodium ascorbate) to standard therapy will improve the Cellulitis Visual Score.
Timepoint [2] 259037 0
5 days' following admission to the hospital.
Secondary outcome [1] 265283 0
The secondary objective is to determine if adding high-dose intravenous antioxidant therapy (sodium ascorbate) to standard therapy will reduce a patient's length of stay in hospital. This will be determined from the patient's hospital notes which document the time and date of admission to the hospital until the date and time of discharge.
Timepoint [1] 265283 0
5 days' following admission to the hospital
Secondary outcome [2] 265284 0
The secondary objective is to determine if adding high-dose intravenous antioxidant therapy (sodium ascorbate) to standard therapy is safe and tolerable. This will be assessed using the results from daily Full Blood Count data and reporting of adverse events. Expected events are: Skin ulceration, Serous exudate, Abscess formation, steomyelitis & Discomfort in the vein during infusion. Daily trial nurse assessment and review of the patient's medical record will be used to assess all adverse events.
Timepoint [2] 265284 0
5 days' following admission to the hospital

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The site staff who have been trained on the protocol will contact the Coordinating Centre (GLCC) via telephone when they are ready to perform a randomisation. The required details will be given over the phone and repeated to confirm they are correct. Then the randomisation will be performed by a trained GLCC emplyee using an Oracle database module specifically designed and tested for randomisations. The allocation of study kits to patients will be based on a random list supplied to the GLCC programmer by the independent statistician for use in the randomisation module. When a randomisation has been performed the site staff will receive an email confirming the details so that they can obtain the correct kit number for the patient. Only the statistician and GLCC programmer will be aware of the randomisation schedule in New Zealand.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Then the randomisation will be performed by a trained GLCC emplyee using an Oracle database module specifically designed and tested for randomisations. The allocation of study kits to patients will be based on a random list supplied to the GLCC programmer by the independent statistician for use in the randomisation module.
