Simple calculation of the optimal insertion depth of esophageal temperature probes in children.
Published in Journal of clinical monitoring and computing
Placing an esophageal temperature probe (ETP) in the optimal esophageal site is important in various anesthetic and critical care settings to accurately monitor the core temperature of a pediatric patient. However, no reported study has provided a formula to calculate the optimal insertion depth of ETP placement in children based on direct measurem...
Monitoring the level of hypnosis using a hierarchical SVM system.
Published in Journal of clinical monitoring and computing
Monitoring level of hypnosis is a major ongoing challenge for anesthetists to reduce anesthetic drug consumption, avoiding intraoperative awareness and prolonged recovery. This paper proposes a novel automated method for accurate assessing of the level of hypnosis with sevoflurane in 17 patients using the electroencephalogram signal. In this method...

Influence of different PEEP levels on electrical impedance tomography findings in patients under general anesthesia vent...
Published in Journal of clinical monitoring and computing
To determine the effect of various PEEP levels on electrical impedance tomography (EIT) measured differences in regional ventilation, hemodynamics, lung mechanics and parameters of alveolar gas exchange. Thirty three patients scheduled for elective urologic surgery in general anesthesia in lateral decubitus position were randomized into three group...
Neuroanesthesiologists as interoperative neurophysiologists: a collaborative cognitive apprenticeship model of training ...
Published in Journal of clinical monitoring and computing
Directing intraoperative neurophysiologic monitoring (IONM) is a patient care activity for which no formal training programs exist, even though the need for well-trained practitioners is readily evident while caring for patients with diseases of the brain, spinal cord, spinal column, or nervous system. Here, we present the theoretical basis and ins...

Validation of electrical velocimetry in resuscitation of patients undergoing liver transplantation. Observational study....
...Published in Journal of clinical monitoring and computing
Major hemodynamic changes are frequently noted during liver transplantation (LT). We evaluated the performance of electrical velocimetry (EV) as compared to that of TEE in SV optimization during liver transplantation. This was an observational study in 32 patients undergoing LT. We compared SV values measured simultaneously by EV (SVEV) and TEE (SV...
Ephedrine and phenylephrine induce opposite changes in cerebral and paraspinal tissue oxygen saturation, measured with n...
Published in Journal of clinical monitoring and computing
While the effects of phenylephrine (PE) and ephedrine (E) on cerebral oxygen saturation (rScO2) already has been studied, the effect on paraspinal oxygen saturation (rSpsO2) is still unexplored. This study aims to assess the effect of PE and E on rScO2 and rSpsO2, measured with near-infrared spectroscopy. A randomized 4-treatment cross-over trial w...
Comparison of cardiovascular parameter estimation methods using swine data.
Published in Journal of clinical monitoring and computing
In this study, new and existing methods of estimating stroke volume, cardiac output and total peripheral resistance from analysis of the arterial blood pressure waveform were tested over a wide range of conditions. These pulse contour analysis methods (PCMs) were applied to data obtained in six swine during infusion of volume, phenylephrine, dobuta...
