Open AccessRecovery of cardiac electrophysiological alterations by heart rate complexity based on multiscale entropy following liver transplantation
Autonomic nervous dysfunction is a known cardiac sequalae in patients with end-stage liver disease and is associated with a poor prognosis. Heart rate analysis using nonlinear models such as multiscale entropy...

Open AccessEfficacy and safety of remifentanil for endoscopic ultrasound-guided tissue acquisition: a single center retrospective study
Remifentanil is a rapid onset and rapid recovery opioid. The combination of remifentanil and propofol for deep sedation decreases the incidents of movement, cough, and hiccup. We evaluated the efficacy and saf...

Relationship of abdominal circumference and trunk length with spinal anesthesia level in the term parturient
We hypothesized that body shape metrics influence the anatomy of spinal canal and intraabdominal pressure in three dimensions. We explored the effects of abdominal circumference, trunk length, and their combin...

Using a short-term parameter of heart rate variability to distinguish awake from isoflurane anesthetic states
The measurement of anesthetic depth is important in anesthesiology. Although heart rate variability (HRV) is profoundly affected by general anesthesia, it has not yet been commonly used in this field. One of t...

Time-Frequency Analysis of Heart Rate Variability During Transient Segments
The spectral characteristics of heart rate variability (HRV) are related to the modulation of the autonomic nervous system. As the physiological condition is changed by such external stimuli such as drugs, pos...
