Abstract
OBJECTIVE: To explore the effects of blood glucose control on glucose variability and clinical outcomes in patients with severe acute pancreatitis in intensive care unit (ICU). METHODS: A total of 72 ICU patients with severe acute pancreatitis were recruited and divided randomly into observation and control groups (n = 36 each). Both groups were treated conventionally. And the observation group achieved stable blood glucose at 6.1-8.3 mmol/L with intensive glucose control. The length of ICU and hospital stays, ICU mortality rate, transit operative rate, concurrent infection rate, admission blood glucose, glycosylated hemoglobin, mean insulin dose, mean blood glucose, blood glucose value standard deviation (GLUSD), glycemic liability index (GLUGLI) andmean amplitude of glycemic excursion (GLUMAGE) of two groups were compared. At the same time, the relationship between blood glucose variability, ICU mortality rate and its predictive value were analyzed by correlation analysis and receiver operating characteristic curve (ROC). RESULTS: The lengths of ICU and hospital stays of observation group were all significantly less than those of the control group [(11.7 ± 9.9) vs (15.9 ± 8.02) days, (21.8 ± 10.8) vs (28.2 ± 12.7) days, P < 0.05]. In observation group, the rates of pulmonary infection (27.78%) and hematogenous infection (5.56%) were all significantly lower than those of control group (72.22%, 38.89%, P < 0.05). The values of mean blood glucose value and GLUSD of observation group were significantly lower than those of control group [(7.4 ± 1.1) vs (9.6 ± 1.2), (1.8 ± 1.0) vs (2.5 ± 1.3) mmol/L]. The differences were statistically significant (P < 0.05). While the dose of insulin [(70.2 ± 47.6) vs (34.4 ± 38.6) U/d] was significantly higher than that of control group (P < 0.05). Bivariate correlation analysis showed that ICU mortality rate was positively correlated with GLUGLI (r = 0.368, P < 0.05). ROC curve analysis showed that, AUC of GLUGLI was 0.748 and 95% CI 0.551-0.965 (P < 0.05). CONCLUSION: Intensive glucose control in patients with severe acute pancreatitis helps reduce the blood sugar fluctuations, lower the risks of infectious complications and promote the patient rehabilitation. And GLUGLI is positively correlated with ICU mortality rate. It has good predictive values.
