BACKGROUND: Hypertonic sodium chloride solutions are routinely used to control raised intracranial pressure (ICP) after traumatic brain injury but have the potential to cause a hyperchloremic metabolic acidosis. Sodium bicarbonate 8.4% has previously been shown to reduce ICP and we have therefore conducted a randomized controlled trial to compare these two solutions. METHODS: Patients with severe traumatic brain injury were randomly allocated to receive an equiosmolar dose of either 100 ml of sodium chloride 5% or 85 ml of sodium bicarbonate 8.4% for each episode of intracranial hypertension. ICP and blood pressure were measured continuously. Arterial pCO(2), sodium, chloride, osmolality, and pH were measured at intervals. RESULTS: We studied 20 episodes of intracranial hypertension in 11 patients. Treatments with 8.4% sodium bicarbonate and 5% sodium chloride reduced raised ICP effectively with a significant fall in ICP from baseline at all time points (P < 0.001). There was no significant difference in ICP with time between those episodes treated with 5% sodium chloride or 8.4% sodium bicarbonate, P = 0.504. Arterial pH was raised after treatment with 8.4% sodium bicarbonate. CONCLUSIONS: An equiosmolar infusion of 8.4% sodium bicarbonate is as effective as 5% sodium chloride for reduction of raised ICP after traumatic brain injury when infused over 30 min.
