Achieving optimal fluid balance for a patient undergoing major surgery, especially transplant surgery, has always been the lofty goal of peri-operative care,1 which often proves to be an elusive target. While keeping the patient well hydrated improves organ perfusion, being too generous with fluids can result in morbidity, such...

Dear Editor, Chronic kidney disease (CKD) is one of the key complications occurring in 25–40% of patients with type 2 diabetes mellitus (T2DM).1 Our earlier study also showed that CKD was present in 53% of patients with T2DM recruited from a secondary care diabetes centre and primary care polyclinic...

Dear Editor, Acute lower respiratory infections (ALRIs) are a leading cause of under-5 mortality globally—two-thirds could be attributable to respiratory viral infections (RVIs).1,2 The burden of paediatric RVIs in settings of tropical climate with year-long virus circulation is relatively underreported.3,4 Previous studies in these areas have estimated that around 8–11%...

An 81-year-old man who had been fully vaccinated against COVID-19 was admitted to the medical intensive care unit on day 5 of his COVID-19-induced pneumonia for high flow nasal oxygen treatment.

Dear Editor, End-stage renal disease (ESRD) patients have higher mortality, hospital admissions and invasive procedures towards the end of life.1 However, many of them (82%) prioritise minimising suffering over life prolongation. Although twice as many patients prefer dying at home and inpatient hospice (65%) compared to hospital (27%), hospice utilisation...

End-stage renal disease (ESRD) is a challenging and growing health issue, with number of patients increasing globally. The use of dialysis has greatly improved the survival and life expectancy of ESRD patients. Haemodialysis (HD) and peritoneal dialysis (PD) are 2 broad dialysis modalities used for ESRD. Despite the advancement...

Following the rapid advances in medical therapy and critical care technology over the past 30 years, coupled with the spiralling cost of medical care, outcome analysis including mortality risk prediction has become a challenge for the modern day intensivists.
