ABSTRACT

Objective:

To evaluate the predictive value of regional cerebral oxygen saturation (rScO 2) for the occurrence of sepsis-associated encephalopathy (SAE).

Methods:

The data of 94 patients with sepsis admitted to the intensive care unit of Nanjing Drum Tower Hospital from September 2019 to June 2021 were collected. The patients were divided into SAE group and non-SAE group according to the evaluation results of daily intensive care unit confusion assessment method (CAM-ICU) during ICU treatment. The general data such as age and gender of the patients, rScO 2 on 1, 2, 3, 5, and 7 days of ICU admission, and prognostics were recorded. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of rScO 2 on SAE during ICU stay.

Results:

All 94 patients were enrolled in the analysis, of whom 59.6% (56/94) were male, and the mean age was (50.1±15.1) years old; the incidence of SAE was 31.9% (30/94). The levels of rScO 2 within first 3 days of ICU admission in the SAE group were significantly lower than those in the non-SAE group (1 day 0.601±0.107 vs. 0.675±0.069, 2 days 0.592±0.090 vs. 0.642±0.129, 3 days 0.662±0.109 vs. 0.683±0.091, all P < 0.05). However, there was no significant difference in rScO 2 level on the 5th or the 7th day between the SAE and non-SAE groups (5 days 0.636±0.065 vs. 0.662±0.080, 7 days 0.662±0.088 vs. 0.690±0.077, both P > 0.05). ROC curve analysis showed that 1-day rScO 2 had the greatest predictive value for SAE [1 day area under the ROC curve (AUC) = 0.77, 95% confidence interval (95% CI) was 0.65-0.89, P < 0.01; 2 days AUC = 0.60, 95% CI was 0.48-0.72, P > 0.05; 3 days AUC = 0.55, 95% CI was 0.41-0.68, P > 0.05]; with 1-day rScO 2 = 0.640 as the diagnostic threshold, the sensitivity was 73.4%, the specificity was 80.0%. Compared with the non-SAE group, the length of ICU stay and hospital stay in the SAE group were significantly longer [length of ICU stay (days) 13.6±7.1 vs. 9.0±4.3, length of hospital stay (days) 20.1±8.0 vs. 15.8±6.1, both P < 0.05], but the ICU mortality between the two groups was not statistically different.

Conclusions:

The incidence of SAE is relatively high in ICU patients, and the occurrence of SAE can be predicted by monitoring rScO 2. The rScO 2 value on the first day of ICU admission is closely related to the occurrence of SAE, and may be the target of sepsis resuscitation to guide the treatment and improve the long-term prognosis.
