Perioperative N-acetylcysteine (NAC) inhalation significantly reduced postoperative pulmonary complications (PPCs) in liver transplant patients. This treatment also improved patient outcomes and survival rates following orthotopic liver transplantation (OLT).

Area of Science:

  • Anesthesiology and Critical Care Medicine
  • Transplantation Surgery
  • Pulmonary Medicine

Background:

  • Postoperative pulmonary complications (PPCs) are a major concern after orthotopic liver transplantation (OLT), leading to significant morbidity and mortality.
  • The potential benefits of N-acetylcysteine (NAC) inhalation for mitigating PPCs in OLT patients remain largely unexplored.

Purpose of the Study:

  • To prospectively evaluate the efficacy of inhaled N-acetylcysteine (NAC) in reducing the incidence of PPCs following OLT.
  • To assess the impact of NAC inhalation on patient outcomes and survival rates in the OLT population.

Main Methods:

  • A prospective randomized controlled trial involving 60 patients undergoing OLT, randomized to receive inhaled NAC or placebo (sterilized water).
  • NAC or placebo was administered for 30 minutes pre-surgery and 3 hours post-reperfusion.

  • Assessment of PPC incidence, patient survival, and measurement of inflammatory biomarkers (TNF-α, IL-8, CC16, ICAM-1) and antioxidant (SOD) in exhaled breath condensate and serum.

    • Main Results:

    • Inhaled NAC significantly decreased the incidence of PPCs after OLT.
    • NAC administration led to lower levels of inflammatory markers (TNF-α, IL-8, CC16, ICAM-1) and higher SOD activity in both exhaled breath condensate and serum.
    • The NAC group demonstrated improved patient outcomes compared to the control group.

    Conclusions:

    • Perioperative N-acetylcysteine (NAC) inhalation is an effective strategy for reducing postoperative pulmonary complications in patients undergoing orthotopic liver transplantation (OLT).
    • NAC inhalation may improve overall patient outcomes and survival rates after OLT, warranting its consideration in clinical practice.
