The Sustained Attention to Response Test (SART) is a feasible tool for assessing cognitive function after anesthesia. General anesthesia increased errors but not reaction time, while local anesthesia affected both.

Area of Science:

  • Anesthesiology
  • Neuroscience
  • Cognitive Psychology

Background:

  • Postoperative cognitive dysfunction is a concern following anesthesia.
  • Assessing cognitive deficits is often time-consuming and challenging.
  • The Sustained Attention to Response Test (SART) offers a potential solution for efficient evaluation.

Purpose of the Study:

  • To evaluate the feasibility of using the SART.
  • To assess cognitive function in patients undergoing surgery under general versus local anesthesia.
  • To compare the impact of different anesthetic techniques on sustained attention.

Main Methods:

  • A pilot study involving 60 adult patients (ASA I-II).
  • Patients underwent day case surgery under general or local anesthesia.

  • The SART was administered pre-operatively and 2 hours post-operatively.

    • Main Results:

    • Following local anesthesia, patients showed increased errors and decreased reaction times on the SART (P < 0.05).
    • General anesthesia led to an increase in errors but no significant change in reaction times (P < 0.05).
    • The SART demonstrated sensitivity to changes in cognitive performance post-surgery.

    Conclusions:

    • The SART is a simple and potentially valuable tool for assessing postoperative cognitive deficits.
    • It can be effectively used to compare the effects of general and local anesthesia on sustained attention.
    • Further research can explore its utility in diverse surgical and anesthetic contexts.
