“…The ANI‐guided technique during general anesthesia is aimed at monitoring intraoperative nociception, to titrate the dose of analgesics, and also to predict hemodynamic changes after noxious stimuli. Variations in ANI score have been shown to allow the early prediction of risk of spinal anesthesia‐related maternal hypotension in cesarean section 7 . Moreover, some studies showed that ANI decreased the amount of opioid consumption 8 and was associated with better recovery in the postanesthetic care unit 9 .…”

“…Patients in most studies received a 500-1000 mL crystalloid preload 11,12 or 500-2000 mL crystalloid coload. [13][14][15] Other studies used 500-mL colloid preload 10,16 or coload 17 as fluid infusion strategy. Vasopressors used to treat spinal anesthesia-induced hypotension were bolus doses of ephedrine 5-15 mg and/or phenylephrine 25-100 µg in most studies.…”

A variety of techniques are available for assessment, including three main methods: fast Fourier transformation (LF/HF), 10 wavelet transformation, 13 and point correlation dimension (PD2). 27 Chamchad et al 27 initially proposed HRV as a predictive tool for spinal anesthesia-induced hypotension in 22 patients using point correlation dimension (PD2), reporting 100% accuracy.…”

Analgesia nociception index and high frequency variability index: promising indicators of relative parasympathetic tone

2022

View full text Add to dashboard Cite

At present, there is no objective and absolute measure of nociception, although various monitoring techniques have been developed. One such technique is the Analgesia Nociception Index (ANI), which is calculated from heart rate variability that reflects the relative parasympathetic tone. ANI is expressed on a non-unit scale of 0–100 (100 indicates maximal relative parasympathetic tone). Several studies indicated that ANI-guided anesthesia may help reduce intraoperative opioid use. The usefulness of ANI in the intensive care unit (ICU) and during surgery has also been reported. However, some limitations of ANI have also been reported; for example, ANI is affected by emotions and some drugs. In 2022, a high frequency variability index (HFVI), which was renamed from ANI and uses the same algorithm as ANI, was commercialized; therefore, ANI/HFVI are currently in the spotlight. Unlike ANI, HFVI can be displayed along with other biometric information on the Root ® monitor. ANI/HFVI monitoring may affect the prognosis of not only patients in the perioperative period but those in ICU, those who receive home medical care, or outpatients. In this article, we present an updated review on ANI that has been published in the last decade, introduce HFVI, and discuss the outlooks of ANI/HFVI.
