Alistair D. Nichol is an intensivist working in Melbourne, based at Commercial Road, Melbourne VIC 3004. He looks after people when they’re very unwell and need close monitoring and quick, careful decision-making.
In intensive care, things can change fast. Alistair supports patients dealing with serious breathing problems and infections, including conditions like pneumonia, sepsis, and COVID-19. He also helps manage situations where the brain or body has been affected by lack of oxygen, such as cerebral hypoxia and increased intracranial pressure.
Cardiac emergencies are another big part of the work. This can include heart failure and cardiac arrest, where treatment has to start quickly and continue step by step. At times, the care also needs to cover complications that affect blood flow and clotting, like pulmonary embolism and other forms of venous thromboembolism (VTE), including deep vein thrombosis.
Injuries and sudden illness can also bring people into intensive care. For example, traumatic brain injury and the period after a craniectomy can require careful follow-up and ongoing support. Alistair’s role is to help stabilise patients, guide treatment, and work with the wider team so care stays on track day to day.
Metabolic and fluid balance matters in the ICU too. At times patients also need help with problems such as metabolic acidosis, low phosphate levels, and severe dehydration or malnutrition. There are also cases involving high breathing rates or breathing that is out of control, such as hyperventilation, where the goal is to bring things back to a safer place.
Alistair also works with patients dealing with fever and major viral illnesses, including flu and SARS. Depending on the case, care may include managing complications like increased pressure in the body, ongoing pain, and complications in the gut, such as peptic ulcer issues or mesenteric venous thrombosis.
Overall, his work focuses on acute, high-stakes care. It’s about being calm under pressure, paying attention to the details, and helping patients through the most critical parts of their illness, with support from the hospital team.
