20 year old male cyclist is hit by a car. On the primary evaluation the GCS was 9 points and quickly deteriorated to a maximum of 6, but the breathing and hemodynamic status were initially stable. The patient was intubated, mechanically ventilated and mannitol infusion was started during the transport. On emergent CT scan of the head only diffuse brain oedema is found with no focal lesions of the brain parenchyma or intracranial hematomas. CT scan of the neck, chest and abdomen shows clear spine, fractures of fourth and fifth ribs on the right, no pleural fluid or air collections, intact heart and great vessels, no injuries to the abdominal organs or free fluid in the abdominal cavity. The patient is admitted in the ICU. Which of the suggested monitoring is not part of the initial management of that patient?

A 12-year old boy with unremarkable previous medical history regularly vaccinated, was hospitalised two days ago with flu-like symptoms, abdominal pain and vomiting. His condition was gradually worsening with changes in, mentation (GCS initialty was 15 now is 12), rapid and noisy breathing arterial hypotension (BP 95/50 MmHg), oliguria (after initial polyuria), hyperthermia, with 38.8°C despite the antiviral (Oseltamivir) and the symptomatic therapy that were started initially. You run a blood and urine analysis and receive the following results: arterial blood pH 7.0, PaCO2 20 mmHg. BE (-16), [HCO3-] 10 mmol/L, blood glucose 2 mmol/L, [K+] 3.4 mmol/l, [Na+] 132 mmol/L, [Cl-] 90 mmol/L, and serum creatinine 60 μmol/l, urea 3 μmol/l, 4(+) glucose and 3(+) ketones in urine
What are the first therapeutic intervention you would start with in this case?
