Infusing lactated Ringer's solution with oxygen (Oxygen-LR) did not improve blood oxygenation in surgical patients. This study found Oxygen-LR has no clinical value for enhancing oxygen delivery compared to standard lactated Ringer's solution.

Area of Science:

  • Anesthesiology
  • Critical Care Medicine
  • Physiology

Background:

  • Maintaining adequate blood oxygenation is crucial during surgery.
  • Epidural anesthesia is used for abdominal surgeries.
  • Intravenous fluid administration is common during surgical procedures.

Purpose of the Study:

  • To investigate the effect of oxygen-infused lactated Ringer's solution (Oxygen-LR) on blood oxygenation.
  • To compare Oxygen-LR with standard lactated Ringer's solution (LR) in patients undergoing abdominal surgery.
  • To determine the clinical utility of Oxygen-LR for improving oxygen transport.

Main Methods:

  • A randomized controlled study involving 23 patients undergoing abdominal surgery under epidural anesthesia.
  • The oxygen-LR group (n=12) received 1000 ml of LR inflated with oxygen at 1 L/min over 30 minutes.

  • The control group (n=11) received 1000 ml of standard LR over 30 minutes.

    • Main Results:

    • The partial pressure of oxygen in arterial blood (PaO2) in the oxygen-LR group increased significantly during infusion.
    • However, there were no significant differences in PaO2, PaCO2, SatO2, or A-aDO2 between the oxygen-LR and control groups during or after infusion.
    • The oxygen-LR solution demonstrated a low capacity for carrying oxygen.

    Conclusions:

    • Oxygen-LR infusion does not significantly improve systemic blood oxygenation parameters in patients undergoing abdominal surgery under epidural anesthesia.
    • The study suggests that Oxygen-LR has no clinical value for enhancing oxygen transport compared to standard LR.
    • Further research may be needed to explore alternative methods for oxygen delivery during anesthesia.
