Abstract:
Objective:To analyze the value of renal color Doppler ultrasound examination and clinical indicators in evaluating the severity and prognosis of acute organophosphorus pesticide poisoning (AOPP) complicated by acute kidney injury (AKI) .Methods:In November 2019, 86 AOPP patients complicated by AKI who were admitted from May 2018 to May 2019 were selected as the observation group, and they were divided into AKI stage 1 group ( n=37) , AKI stage 2 group ( n=32) and AKI stage 3 group ( n=17) . 40 healthy people were selected as the control group. The differences in power Doppler ultrasound (PDU) score, renal interlobular artery resistance index (RI) value and related clinical indicators of each group were measured and analyzed, and the correlations between the indicators were analyzed. At the same time, binary logistic regression was used to analyze the risk factors of death in AOPP patients complicated by AKI. Results:There were statistically significant differences in Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱscore, mean arterial pressure (MAP) , serum creatinine (SCr) and the length of continuous renal replacement therapy (CRRT) between different groups ( P<0.05) . Compared with the control group, the APACHE Ⅱscores and SCr of patients in the AKI stage 2 and resistance index AKI stage 3 groups increased, while the MAP decreased ( P<0.05) . Compared with the control group, AKI stage 1 group and AKI stage 2 group, the PDU score of patients in the AKI stage 3 group was significantly decreased, and the renal interlobular artery RI value was significantly increased ( P<0.05) . SCr was positively correlated with the RI value of renal interlobular arteries and CRRT days ( r=0.435, 0.713, P<0.05) , and was negatively correlated with renal PDU score ( r=-0.643, P<0.05) . The renal PDU score was negatively correlated with the RI value of renal interlobular arteries and CRRT days ( r=-0.350, -0.556, P<0.01) . Binary logistic regression analysis showed that SCr ( OR=1.017, 95% CI: 1.004-1.041) and APACHE Ⅱ score ( OR=1.289, 95% CI: 1.019-1.827) were risk factors for death in patients with AOPP complicated by AKI ( P<0.05) . Conclusion:Both PDU score and the RI value of renal interlobular artery can reflect the severity and stage of patients with AOPP complicated by AKI to a certain extent, but neither of them is a key factor affecting the death of patients.
