Abstract

Purpose

Preventive treatments of traumatic intracranial hypertension are not yet established. We aimed to compare the efficiency of half-molar sodium lactate (SL) versus saline serum solutions in preventing episodes of raised intracranial pressure (ICP) in patients with severe traumatic brain injury (TBI).

Methods

This was a double-blind, randomized controlled trial including 60 patients with severe TBI requiring ICP monitoring. Patients were randomly allocated to receive a 48-h continuous infusion at 0.5 ml/kg/h of either SL (SL group) or isotonic saline solution (control group) within the first 12 h post-trauma. Serial measurements of ICP, as well as fluid, sodium, and chloride balance were performed over the 48-h study period. The primary outcome was the number of raised ICP (≥20 mmHg) requiring a specific treatment.

Results

Raised ICP episodes were reduced in the SL group as compared to the control group within the 48-h study period: 23 versus 53 episodes, respectively (p < 0.05). The proportion of patients presenting raised ICP episodes was smaller in the SL group than in the saline group: 11 (36 %) versus 20 patients (66 %) (p < 0.05). Cumulative 48-h fluid and chloride balances were reduced in the SL group compared to the control group (both p < 0.01).

Conclusion

A 48-h infusion of SL decreased the occurrence of raised ICP episodes in patients with severe TBI, while reducing fluid and chloride balances. These findings suggest that SL solution could be considered as an alternative treatment to prevent raised ICP following severe TBI.
