Arterial-jugular bulb differences in pCO2, lactate, serum sodium and C-reactive protein in neurocritical patients
Critical Care volume 18, Article number: P460 (2014)
Introduction
Methods
An observational study. Between 1 January and 31 October 2013 we included neurocritical patients (NCP) with multimodal neuromonitoring (MMN). Daily samples of arterial blood and venous jugular bulb blood were obtained for measuring pCO2, lactate, serum sodium and CRP.
Results
There were 45 NCP, six (13%) with MMN (five men). Mean age was 37 ± 11 years (35 to 61). Diagnostics: two TBI, two SAH, one stroke, one lupus encephalitis. APACHE II was 27 ± 6.5 (25 to 39). Glasgow Coma Scale at admission was 14 ± 4 (4 to 14). pCO2 (mmHg): arterial 41 ± 6.3 versus jugular 45 ± 7.4 (r = 0.7, P = 0.007). Lactate (mg/dl): arterial 11 ± 5.6 versus jugular 13.5 ± 3.9 (r = 0.7, P = 0.9). Sodium (mEq/dl): arterial 141 ± 4.5 versus 141 ± 4.4 (r = 0.8, P = 0.15). CRP (mg/dl): arterial 8 ± 7.4 versus 17 ± 11.6 (r = 0.9, P < 0.001). The correlation and trend curves are shown in Figure 1.
Conclusion
A suitable correlation is observed for the arterial-jugular bulb in different variables. There is a significant difference in CRP and pCO2 values being persistently higher in the jugular, particularly for CRP. Studies are required to define its interpretation and potential usefulness.
