Utilidad clínica de la monitorización de la saturación de oxígeno en el bulbo de la yugular en los pacientes con traumatismo craneoencefálico grave

Objective: To study the relationship between the oxygen saturation measured at the jugular bulb (SatY O-2) with cerebral computerized tomography (CT) findings and mortality in severe head injury patients.Material and methods: We studied 28 severe head injury patients (Glasgow Coma Score: 6 +/- 2 at admission). SatY O-2 and lactate-oxygen index were measured through a conventional catheter implanted at one jugular bulb. CT brain injuries were classified as diffuse, focal or mixed.Results: We performed 282 analytic determinations of jugular blood samples and classified the hemodynamis status as hyperemic, normal, hypoperfusion and ischemic. 81% of the survivors had SatY O-2, value within normal limits in comparison to only 19% of patients who died (p < 0.007). However, there was no a significant correlation between SatY O2 values and the CT findings.Conclusion: Oxigen saturation measured at the yugular bulb correlated with mortality rate In severe head injury patients but the different hemodynamic patterns did not associate with the intracranial pathology an estimated by CT scan.
