A 52 year old female was admitted to the ICU with septic shock secondary to cholangitis. She had liver cirrhosis secondary to alcoholic liver disease, although she had been abstinent since an admission with acute alcoholic hepatitis 2 years previously. She had recently entered the assessment pathway for orthotopic liver transplantation.
She presented to the Emergency Department with a short history of fever and confusion and falls. She was pyrexial, tachycardic and hypotensive. Her inflammatory markers were elevated and her liver enzyme profile suggested cholestasis. There were no other localising features on examination or preliminary investigation.
She was commenced in the ED on broad-spectrum antibiotic therapy (piperacillin-tazobactam) and fluid resuscitation consisting of Hartmann’s solution and 4% human albumin solution. Her blood pressure remained labile throughout the early part of her admission. She fulfilled the criteria for septic shock with evidence of evolving multi-organ dysfunction.
The patient received early, aggressive multi-organ support. Tracheal intubation and pressure-controlled ventilation were instituted due to grade III/ IV encephalopathy and a high work of breathing in response to profound metabolic acidaemia. A thorough clinical assessment of intravascular volume status was conducted, suggesting that the patient was adequately filled. Vasopressor therapy was initiated using noradrenaline to achieve a target MAP of 65mmHg. CVVHDF was commenced to control the severe acidaemia and hyperlactataemia.
The patient was vasoplegic and remained profoundly hypotensive despite rapidly escalating doses of noradrenaline and the addition of hydrocortisone. Continued assessment of intravascular status confirmed adequate filling and cardiac output monitoring using a pulse-contour analysis system confirmed a low SVRI- high cardiac output state. Her noradrenaline requirements soon exceeded 0.4mcg/kg/min-1, at this point a vasopressin infusion was introduced at 0.03units/hr-1. This was associated with an improvement in haemodynamic indices; the target MAP was achieved and thereafter remained stable with a slow reduction in noradrenaline requirement. On day 2 the continuous vasopressin infusion was converted to terlipressin by bolus dose regime (2mg QDS).
An urgent ultrasound scan of her biliary system revealed an obstructed common bile duct which was treated by percutaneous biliary drainage. An Enterococcus was isolated from drain fluid and blood cultures within 48 hours and antibiotic therapy tailored accordingly. The patient was weaned from organ support and discharged to the hepatology unit 9 days after admission.
What is the rationale for the use of vasopressin in septic shock? Are vasopressin analogues as effective?Read More »
