In recent years,extracorporeal membrane oxygenation (ECMO) has been increasingly used in clinical practice as a critical advanced life support modality for critically ill patients with acute respiratory/circulatory failure. These patients often develop complications such as acute kidney injury(AKI) and volume overload,necessitating renal replacement therapy (RRT). The indications and optimal timing for initiating continuous renal replacement therapy (CRRT) should be determined through individualized assessment based on the patient's volume status and severity of AKI-related metabolic disturbances. In ECMO patients,CRRT can be connected to ECMO in various ways,and there is currently no evidence to suggest different methods of combining ECMO and CRRT affect clinical outcomes. The combined use of ECMO and CRRT is a safe and effective technique to improve fluid balance and stabilize the internal environment. We focus on interpreting key clinical issues that addressed in thePractice Standards for Adult Extracorporeal Membrane Oxygenation Technology (2024 Edition),including indications,timing,connection methods,prognosis and risk factors associated with ECMO-CRRT combined therapy.

Objective

To summarize the single-center experience,clarify its clinical prognosis and complications of piatients who received prolonged ECMO,and propose management strategies.

Methods

The date of 17 critically ill patients who received prolonged ECMO (≥14 days) life support in ICU of Peking Union Medical College Hospital from 2020 to 2023 were retrospectively analyzed,including their treatment strategies,ECMO-related complications,comorbidities,and survival prognosis.

Results

Of the 17 patients,14 received VV-ECMO and 3 received VA-ECMO. The Long-ECMO(Etiology-Coagulation-Multidisciplinary-Organ) management strategy was applied. The duration of ECMO support was 29 (24,34) days,with the longest duration being 88 days. Eleven patients received vasoactive drugs simultaneously,7 patients received CVVH treatment,and all 17 patients exhibited hemorrhagic complications,including 15 patients presenting with local hemorrhages at the ECMO catheterization site,3 patients developing thigh hematoma,13 patients experiencing nasal cavity bleeding,3 patients manifesting airway hemorrhages,2 patients with intracranial hemorrhages,and 3 patients displaying gastrointestinal bleeding. Five patients had positive blood cultures,and 4 patients had pneumothorax. Nine patients (52.9%) successfully withdrew from ECMO,and 8 patients survived during hospitalization (47.1%).In the subgroup of 14 VV-ECMO patients,there was no difference in the ECMO support time and age between the survival group (7 cases) and the non-survival group (7 cases) [ECMO support time:(29.0±11.2) days vs(33.9±24.9) days,P=0.647; age:(65.6±6.9) years vs (69.6±14.5) years,P=0.522]. However,the baseline APACHE Ⅱ score in the non-survival group was significantly higher with statistically significant difference[(26.3±9.2) scores vs (14.6±1.9) scores,P=0.006].

Conclusions

The prolonged ECMO management strategy can save the lives of critically ill patients. Attention should be paid to the prevention and treatment of complications and organ repair,and it also has certain application value in elderly patients.

Non-occlusive mesenteric ischemia is characterized by ischemic injury or necrosis of the intestine stemming from non-obstructive causes. One of the major risk factors for non-occlusive mesenteric ischemia in shock patients is the decrease in blood volume within the circulatory system. Early enteral nutrition during shock may exacerbate the imbalance between the oxygen supply and demand of the intestines,thus facilitating the development of non-occlusive mesenteric ischemia. Nevertheless,diagnosing non-occlusive mesenteric ischemia in critically sick patients is typically challenging,as it is linked to a significant risk of death. This paper will review the advancements on the risks and preventive measures of non-occlusive mesenteric ischemia induced by early enteral nutrition in shock states,which aim to provide support for improving the prognosis of non-occlusive mesenteric ischemia.

Fluid resuscitation plays an important role in the treatment of septic shock. For adults with sepsis or septic shock,crystalloid is recommended as first-line fluid for resuscitation in the latest Surviving Sepsis Campaign guidelines. The specific type of crystalloid given is still controversial. Saline is prone to hyperchloremia due to high chloride concentration and has adverse effects on the renal function. Balanced crystalloids are of interest to clinicians because their composition are closer to extracellular fluid of human body. In this paper,the advantages and disadvantages of different crystalloids and their selection were summarized based on the research of the influence of crystalloids on acute kidney injury in patients with septic shock in recent years.
