Management of Hypertension in Septic Patients with Renal Dysfunction

Understanding the Clinical Context

The Society of Critical Care Medicine recommends focusing exclusively on treating sepsis with aggressive fluid resuscitation, vasopressors to maintain MAP ≥65 mmHg, early antibiotics, and supportive renal replacement therapy as needed in septic patients with impaired renal function who develop hypertension 1, 2, 3
In septic shock with hypotension, vasopressor support is required to maintain adequate perfusion pressure, according to the European Society of Intensive Care Medicine 1, 2, 3

The American College of Critical Care Medicine recommends administering at least 30 mL/kg of isotonic crystalloids within 3 hours, targeting MAP ≥65 mmHg, and obtaining blood cultures and initiating broad-spectrum antibiotics within 1 hour of sepsis recognition 1, 3
The International Society of Nephrology suggests using norepinephrine as first-line vasopressor if MAP remains <65 mmHg despite fluid administration 1, 2, 3

The Society of Critical Care Medicine recommends targeting MAP ≥65 mmHg with norepinephrine as the first-line agent 1, 2, 3

The European Renal Association recommends using continuous renal replacement therapy (CRRT) rather than intermittent hemodialysis if the patient is hemodynamically unstable, as CRRT facilitates fluid balance management during aggressive resuscitation 1, 2, 3, 4
The International Society of Nephrology suggests initiating RRT only for definitive indications: severe acidosis, hyperkalemia, uremic complications, or refractory volume overload 1, 2, 3, 4

The American Diabetes Association recommends targeting blood glucose ≤180 mg/dL using protocolized insulin therapy, avoiding tight control (≤110 mg/dL) 1, 2, 3, 4
The Society of Critical Care Medicine suggests monitoring glucose every 1-2 hours until stable, then every 4 hours 1, 3, 4

The American College of Chest Physicians recommends using low-molecular-weight heparin (LMWH) rather than unfractionated heparin for VTE prophylaxis 1, 3, 4
The International Society of Thrombosis and Haemostasis suggests using dalteparin or another LMWH with low renal metabolism, or switching to unfractionated heparin if creatinine clearance <30 mL/min 1, 4

The Infectious Diseases Society of America recommends not withholding antibiotics due to nephrotoxicity concerns, as treatment of sepsis takes absolute priority 3, 4
The Society of Critical Care Medicine suggests not under-resuscitating due to fear of volume overload, as inadequate resuscitation worsens both sepsis-associated AKI and outcomes 3, 4
The European Society of Intensive Care Medicine recommends avoiding colloids (albumin, hydroxyethyl starch) in favor of crystalloids, as colloids increase risk of AKI and do not improve outcomes 2
