Low-dose dopamine does not prevent acute renal failure. This review shows dopamine impairs kidney function and offers no clinical benefit, despite its continued use by surgeons.

Area of Science:

  • Nephrology
  • Pharmacology
  • Surgical Physiology

Background:

  • Low-dose dopamine is frequently used by surgeons to prevent or treat acute renal failure.
  • This practice persists despite a lack of clear clinical evidence supporting its efficacy.

Purpose of the Study:

  • To critically review the physiological basis for the clinical ineffectiveness of low-dose dopamine in acute renal failure.
  • To evaluate the evidence for dopamine's use in various clinical scenarios leading to renal failure.

Main Methods:

  • A comprehensive critical review of English language medical literature was performed.
  • The review focused on the physiological effects of dopamine on renal function and clinical trial outcomes.

Main Results:

  • Dopamine's effect on renal blood flow is debated; anatomical limitations may restrict its impact.
  • Dopamine can negatively affect renal oxygen kinetics, inhibit protective ischemia feedback mechanisms, and potentially worsen tubular injury.
  • Clinical trials have not demonstrated dopamine's efficacy in preventing or altering acute renal failure in conditions like heart failure, cardiac surgery, sepsis, and transplantation.
  • Dopamine use is linked to adverse effects across multiple organ systems, including cardiovascular, pulmonary, and endocrine complications.

Conclusions:

  • The anatomical and physiological properties of the kidney do not support the use of low-dose dopamine for improving renal failure.
  • Clinical trial data consistently show a lack of efficacy for low-dose dopamine in treating acute renal failure.
