Study Arms:
- Active substances (Type: EXPERIMENTAL): Vitamin C: Vitamin C will be mixed as 1500 mg vitamin C in 50ml container, which will then be infused over 30 minutes to 1 hour. The bag will be labeled by the pharmacy as Vitamin C. The dosing schedule is 1500mg every 6 hours for 4 days or until discharge from the ICU.~Hydrocortisone: Hydrocortisone will be mixed as 50 mg of Hydrocortisone in 50 ml of 0.9 % Sodium Chloride. Patients will be treated with hydrocortisone 50mg IV q 6 hourly for 4 days or until ICU discharge.~Thiamine: Intravenous thiamine will be given in a dose of 200mg q 12 hourly for 4 days or until ICU discharge.
- Control (Type: PLACEBO_COMPARATOR): Vitamin C placebo will consist of an identical container of 50cc normal saline (0.9% Sodium Chloride Injection) (but with no vitamin C) and will be labelled vitamin C. Placebo will be infused over 30-60 minutes as per the infusion instructions of the active vitamin. Hydrocortisone placebo will be provided in an identical 50 ml bag of 0.9% Sodium Chloride Injection. Placebo patients will receive a matching vial of 0.9% Sodium Chloride Injection.

Based on this trial design, predict the completion outcome and termination type (if applicable).
