Randomized Controlled TrialEffect of remifentanil on the nonlinear electroencephalographic entropy parameters in propofol anesthesia.
Nonlinear electroencephalographic entropy parameters have been proposed for the assessment of depth of anesthesia. The influence of remifentanil, a commonly used intraoperative opioid, on these parameters, namely approximate entropy (ApEn), sample entropy (SampEn), and permutation entropy (PeEn), during induction of propofol anesthesia was studied. ⋯ No consistent influence on PeEn was observed. However, this may have been due to strong interindividual variation in PeEn values.
