AbstractWe describe the protocolised use of 23.4% hypertonic saline solution (HTS) for intracranial hypertension in the context of traumatic brain injury in the paediatric population. This study represents the largest published data on the use of 23.4% HTS in the paediatric population. In this retrospective cohort, we focus on the efficacy, biochemical and metabolic consequences of 23.4% HTS administration in a Level 1 paediatric trauma centre. Mortality in the first seven days was 6% (2/32) with a mean intensive care unit length-of-stay of ten days (range 2 to 25, standard deviation [SD] 6). All-cause hospital mortality was 6%, with no deaths after the seven-day study period. Mean intracranial pressure (ICP) response to HTS was 10 mmHg (range 1 to 30, SD 8). For biochemistry data, the mean highest daily serum sodium was 148 mmol/l (139 to 161, SD 6), mean highest serum chloride was 115 mmol/l (range 101 to 132, SD 8) with matched mean serum base excess of -1.5 mmol/l (range 2 to -8, SD 3) and mean peak serum creatinine was 73 mmol/l (range 32 to 104, SD 32). Glasgow outcome scores of >3 (independent function) were achieved in 74% of patients. We describe the use of 23.4% HTS, demonstrating it to be a practical and efficacious method of delivering osmoles and may be advantageous in minimising total fluid volume. Thus, the bolus versus infusion debate may best be served via combining both approaches.
