Continuous Analgesia / Nociception balance evaluation during general anesthesia could be of precious help for the optimization of analgesic drugs delivery, limiting the risk of toxicity due to the use of opioid drugs, limiting the risk of post operative hyper algesia, and, probably, reducing time of recovery after surgical procedure. Heart Rate Variability(More)
OBJECTIVES To evaluate spinal curvature changes over a 3-year period in postmenopausal women who had had an osteoporotic vertebral fracture within the last 3 months. METHODS Thoracic kyphosis and lumbar lordosis were measured using a curviscope at baseline and after 1, 3, 6, 12, and 36 months. Anteroposterior and lateral radiographs of the thoracolumbar(More)
The analgesia nociception index (ANI) is an online heart rate variability analysis proposed for assessment of the antinociception/nociception balance. In this observational study, we compared ANI with heart rate (HR) and systolic blood pressure (SBP) during various noxious stimuli in anaesthetized patients. 15 adult patients undergoing laparoscopic(More)
Healthcare monitoring is a general concern for patients requiring a continuous medical assistance and treatment. In order to increase mobility of such patients, a huge effort is pursued worldwide for the development of wearable monitoring systems able to measure vital physiological parameters such as respiratory movements, cardiac activity, pulse oximetry,(More)
We applied to 20 paralyzed ventilated children (0.15 to 14.3 yr, six with acute respiratory distress syndrome [ARDS]) the low-flow inflation (LFI) technique providing quasi-static volume-pressure (V-P) curves and compared the assessment of overdistension (OD) on dynamic and LFI (reference) inspiratory V-P curves. Dynamic curves were obtained at the airway(More)
OBJECTIVES Systems controlling cardiovascular function are closely coupled with the perception of pain. Heart rate variability (HRV) is a well-established noninvasive measure of cardiac autonomic control. We hypothesized that pain may alter HRV in the newborn infant and that HRV analysis could be used as an indicator of prolonged pain in the newborn infant.(More)
AIM To analyse the immediate response of heart rate variability (HRV) in response to orthostatic stress in unexplained syncope. SUBJECTS 69 subjects, mean (SD) age 42 (18) years, undergoing 60 degrees head up tilt to evaluate unexplained syncope. METHODS Based on 256 second ECG samples obtained during supine and upright phases, spectral analyses of low(More)
The optimization of analgesic drugs delivery during general anesthesia requires to evaluate the pain/analgesia balance. Heart rate variability analysis has been shown in several studies to measure the autonomic nervous system tone, which is strongly influenced by anesthetic drugs. Recording RR series during general anesthesia enabled us to observe that the(More)
Healthcare monitoring applications requires the measurement and the analysis of multiple physiological data. In the field of biomedical research, these data are issued from different devices involving data centralization and synchronization difficulties. On the other hand, the analysis of the acquired data requires high level digital signal processing(More)
Heart Rate Variability analysis has been shown in several studies to measure the Autonomic Nervous System tone, which is strongly influenced by pain, stress or anxiety. We have previously described and developed an Analgesia/Nociception Index for pain measurement during surgical procedure. This index based on a heart rate variability analysis can be(More)
