Functional endoscopic sinus surgery (FESS) utilizes adrenaline (epinephrine) for vasoconstriction. Despite systemic absorption, significant cardiac side effects are rare in FESS patients when closely monitored.

Area of Science:

  • Otolaryngology
  • Anesthesiology
  • Pharmacology

Background:

  • Vasoconstrictors like epinephrine are standard in Functional Endoscopic Sinus Surgery (FESS).
  • Concerns exist regarding potential cardiac side effects of epinephrine during FESS.
  • The clinical application of adrenaline in FESS remains a topic of debate.

Purpose of the Study:

  • To evaluate the systemic absorption of adrenaline used in FESS.
  • To assess the incidence of adrenaline-related side effects during FESS.
  • To compare these findings with a control group undergoing tonsillectomy.

Main Methods:

  • A prospective controlled study involving 51 FESS patients and 12 tonsillectomy patients.
  • Measurement of plasma adrenaline concentrations at multiple surgical time points.

  • Monitoring of pulse, ECG, and blood pressure throughout the procedures.

    • Main Results:

    • FESS patients showed a significant decrease in blood pressure but unaffected heart rate.
    • All FESS patients exhibited increased plasma adrenaline levels post-application.
    • No severe adrenaline-related side effects were observed in FESS patients; control group showed transient blood pressure increase.

    Conclusions:

    • Systemic absorption of adrenaline occurs during FESS.
    • Adrenaline-related side effects are rare in FESS when patients are meticulously monitored.
    • The study supports the safe use of adrenaline in FESS under controlled conditions.
