Acute kidney injury management using intermittent low efficiency haemodiafiltration in a critical care unit: 39 dogs (2012–2015)

A thirty-year-old pregnant woman was admitted to hospital with headache and gastrointestinal discomfort. She developed peripheral oedema and had an emergency caesarean section following an episode of tonic-clonic seizures. Her delivery was further complicated by postpartum haemorrhage and she was admitted to the Intensive Care Unit (ICU) for further resuscitation and seizure control which required infusions of magnesium and multiple anticonvulsants. Despite haemodynamic optimisation she developed an acute kidney injury with evidence of liver damage, thrombocytopenia and haemolysis. Haemolysis, Elevated Liver enzymes and Low Platelets (HELLP) syndrome, a multisystem disease of advanced pregnancy which overlaps with pre-eclampsia, was diagnosed. HELLP syndrome is associated with a range of complications which may require critical care support, including placental abruption and foetal loss, acute kidney injury, microangiopathic haemolytic anaemia, acute liver failure and liver capsule rupture. Definitive treatment of HELLP is delivery of the fetus and in its most severe forms requires admission to the ICU for multiorgan support. Therapeutic strategies in ICU are mainly supportive and include blood pressure control, meticulous fluid balance and possibly escalation to renal replacement therapy, mechanical ventilation, neuroprotection, seizure control, and management of liver failure-related complications. Multidisciplinary input is essential for optimal treatment.

The Impact

Renal replacement therapy (RRT) can be used to support patient’s kidney function in cases of acute kidney injury (AKI). However, timing, modality, and dosing of RRT continue to remain in question. Recent studies have begun to provide data to help guide clinicians on when to initiate RRT, what form of RRT to use ranging from continuous venovenous hemofiltration (VVH) to intermittent hemodialysis, and the impact of high versus low-intensity dosing. Additionally, the risks associated with temporary vascular access with regard to thrombosis and infection, the impact of high efficiency and flux versus low efficiency and flux membranes, and options for anticoagulation in RRT for AKI are also discussed.
