“…We first conducted studies on the measurement of HRV in adults under general anesthesia [22] . One study found that our method had a low sensitivity and specificity for postoperative acute-pain evaluation [26] ; yet, a majority of data indicate that our technology allows anesthetists to adapt analgesia during surgical procedures, labor, and postoperative recovery time [22-24, 26, 35] .…”

Objective: We developed a computerized heart-rate variability index related to the fetal parasympathetic activity: the Fetal Stress Index (FSI). The objective was to determine whether the FSI is related to the visual analysis of the fetal heart rate (FHR). Methods: Thirty tracings recorded at a labor ward were classified according to the NICHD categories: (I) normal FHR tracing, (II) intermediate risk of acidosis, and (III) high risk. FSI was calculated as minimum, maximum, and mean, and was evaluated before the onset of the FHR pattern, during the 10 min following, and between 10 and 20 min after that. Results: The FSI for categories II and III was similar to that of category I before the onset of the FHR pattern. FSI min was lower just after the onset of the abnormal FHR in category III, compared with that of category I (33 vs. 43, p < 0.001). Between 10 and 20 min after the onset of the abnormal FHR, we observed a significant reduction in FSI min in categories II and III (44 vs. 39 vs. 29.7, p < 0.0001). Conclusion: Although further studies are necessary for the sake of clinical validation, FSI could constitute an interesting method for the evaluation of fetal well-being.

“…Many studies have demonstrated the ability of our index to investigate the autonomic response to painful stimuli in adults (both conscious and unconscious) [22][23][24][25][26] . We have also demonstrated that our method can be used to assess pain and discomfort in newborn and preterm infants [27] .…”

“…Biz de verilerimizi diğer yayınlarla karşılaştırabilmek amacıyla aynı değerleri eşik değer olarak kabul ettik. Ayrıca ANİ'nin sadece hemodinamik istenmeyen olayların erken saptanması dışında postoperatif ağrı yönetiminde de kullanılabileceğine ve ANİ değerleriyle postoperatif ağrı şiddetinin ön görülebileceğine dair yayınlar da vardır (9,32). Bilindiği üzere ameliyat sonrası oluşan ağrı operasyonun büyüklüğü ile paralel değildir.…”

“…In two studies conducted in the PACU, patients who had undergone surgery under general anesthesia had their ANI monitored prior to extubation. 15,16 It was determined that their ANI correlated negatively with the pain scores on a numeric rating scale (NRS, 0-10 scale) in the PACU. An Australian study 17 monitored the ANI and the NRS pain scores in 120 patients in the PACU after elective surgery and found a weak negative correlation between these two parameters.…”

These findings provide little evidence to support use of the ANI in awake subjects or in awake patients such as those in the emergency room or in the intensive care unit. Nevertheless, based on an important difference between the expected correlation and the real correlation between the ANI and the NRS scores found in our results, the present study might be underpowered. Studies with a larger sample size would be required to enable firm conclusions about the clinical utility of the ANI in this population of awake volunteers as well as in awake patients. This study was registered with ClinicalTrials.gov (NCT02589093).
