BMJ Best Practice 临床实践证据表单
该表单为针对聚焦上述重要临床问题的指南所报道分析（以系统综述为基础）内容进行的总结。
Confidence in the evidence is very low or low where GRADE has been performed and there may be no difference in effectiveness between the intervention and comparison for key outcomes. However, this is uncertain and new evidence could change this in the future.
人群： Adults who are at risk of CI-AKI
干预： Sodium chloride 0.9%
比较： No intravenous hydration, oral fluids, sodium chloride 0.45%, sodium bicarbonate, oral sodium bicarbonate plus oral fluids

Recommendations as stated in the source guideline For inpatients having iodine-based contrast media, consider intravenous volume expansion with either isotonic sodium bicarbonate or 0.9% sodium chloride if they are at particularly high risk; for example, if: They have an eGFR less than 30 ml/min/1.73 m2 They have had a renal transplant A large volume of contrast medium is being used (for example, higher than the standard diagnostic dose or repeat administration within 24 hours) Intra-arterial administration of contrast medium with first-pass renal exposure is being used.
Note The guideline committee undertook both network and pairwise meta-analyses. The results in this table are for the pairwise meta-analysis. The guideline committee noted that evidence from the network meta-analysis showed that sodium chloride 0.9% and sodium bicarbonate appear to be equivalent for preventing CI-AKI. They also noted there was limited evidence on subgroup analyses and that none of those identified showed evidence of an effect from any of the interventions on the incidence of CI-AKI. The guideline committee stated that the primary outcomes for the pairwise analysis were: CI-AKI, CKD progression at 3 months following CI-AKI diagnosis, mortality up to 12 months, need for renal replacement therapy, and adverse events. Other outcomes of interest were: length of hospital stay, readmission for AKI, and health-related quality of life. See the full guideline for details of these additional outcomes.

Cochrane Clinical Answers
Cochrane Clinical Answers (CCAs) provide a readable, digestible, clinically focused entry point to rigorous research from Cochrane systematic reviews. They are designed to be actionable and to inform decision making at the point of care and have been added to relevant sections of the main Best Practice text.
- Do statins help prevent acute kidney injury after surgical procedures requiring cardiac bypass?
- What are the benefits and harms of ischemic preconditioning for reducing renal ischemia reperfusion injury?
