Effect of short-term exercise training on aerobic fitness in patients with abdominal aortic aneurysms.

baseline. On day 12, triglycerides had increased again to 4.6 mmol litre. She died of a pulmonary embolus. Case 2: A 16-yr-old patient who presented with pneumonia after H1N1 influenza. Her serum triglycerides increased from 1.0 to 3.3 mmol litre and reduced after stopping propofol. When it was re-introduced, her serum triglycerides increased again and correlated closely to the propofol infused, reducing after propofol was stopped. Triglycerides increased again on day 12 to 3.9 mmol litre without any propofol infusion. Case 3: A 31-yr-old patient who was 34 weeks pregnant when she contracted H1N1. After 3 days of propofol, her triglycerides had increased from 3.5 to 9.8 mmol litre when propofol was replaced with midazolam. They gradually reduced to 4.3 mmol litre but on day 11 they increased again to 7.3 mmol litre. She died of multiorgan failure. As these patients did not display any features of propofol infusion syndrome, we think the lipid load due to propofol is not being appropriately handled by these patients which is unusual in this young population. There is no mention of triglyceride metabolism disturbance in the oseltamivir data sheet, but this does not seem to have been specifically studied. As routine measurement of triglycerides is not generally carried out in the critically ill on a daily basis, other ICU clinicians may not be aware of this phenomenon. We are not sure of the clinical significance of this observation; however, given that one of our patients died of a pulmonary embolus, we believe that the clinical community should be made aware of disturbed lipid metabolism in these patients.
