Acid-base status before and after arterial clamping.

D B Stokke, B Juhl, G Juel

    Acta Anaesthesiologica Scandinavica

    Summary

    Alkalizing therapy is not necessary after vascular surgery if circulation is stable. Alkalosis can create serious circulatory issues, making routine alkalizing agents inadvisable for patients undergoing vascular procedures.

    Area of Science:

    • Vascular Surgery
    • Anesthesiology
    • Critical Care Medicine

    Background:

    • Intermittent claudication management often involves vascular surgery.
    • Maintaining acid-base balance is crucial during surgical procedures.
    • Alkalizing therapy is sometimes administered post-operatively to correct metabolic disturbances.

    Purpose of the Study:

    • To investigate the necessity of routine alkalizing therapy in patients undergoing vascular surgery.
    • To evaluate the impact of alkalosis on circulatory parameters post-reperfusion.
    • To determine if alkalizing agents are beneficial or detrimental in vascular surgery.

    Main Methods:

    • Study included 10 patients with intermittent claudication undergoing vascular surgery.
    • Circulatory stability, temperature, fluid infusions, and acid-base values were monitored.
    • Alkalizing therapy was withheld unless specific indications arose.

    Main Results:

    • No necessity for alkalizing therapy was found in patients with stable perioperative circulation, normothermia, adequate infusions, and normal pre-clamping acid-base values.
    • Alkalosis was identified as a potential cause of significant circulatory problems, comparable to acidosis.
    • Routine administration of alkalizing agents was deemed inadvisable.

    Conclusions:

    • Stable circulatory parameters and normal acid-base status negate the need for routine alkalizing therapy post-vascular surgery.
    • Alkalosis poses significant risks to circulation, similar to acidosis.
    • Monitoring acid-base values is recommended if unstable circulatory parameters or hypoperfusion are suspected.
