Comparison of the Surgical Pleth Index™ with haemodynamic variables to assess nociception–anti-nociception balance during general anaesthesia

Abstract

SPI, HR, and MAP are of comparable value at gauging noxious stimulation-CeREMI balance. Their interpretation is improved by taking account of IVS, treatment for chronic high arterial pressure, and concordance between their predictions.

Evaluating Natural Ventilation Provisions and Occupants’ Ventilation Behavior in Five Terrace Housing Types in Putrajaya, Malaysia

“…Although the other approaches cannot be considered incorrect, they often cause the loss of information due to the ignoring or collapse of the order and categories of the responses (Ananth and Kleinbaum, 1997;Strand et al, 2012). Numerous studies have broadly employed the ordinal regression model for analysing ordinal DVs in different fields of study, some of which are Bonhomme et al (2010), Košak and Poljšak (2010), Ombui et al (2011), Citko et al (2012, Strand (2012), and Khalaf et al (2013).…”

The Variability of Perfusion Index as a New Parameter in Different Types of Anaesthesia Techniques and Its Correlation with Surgical Stress and Recovery From Anesthesia: An Observational Clinical Study

“…Their interpretation is improved by taking account of IVS, treatment for chronic high arterial pressure, and concordance between their predictions. 43 Elizabeth Douglas studied in 2011 on perfusion Index Used as Tool To Confirm Epidural PlacementThe perfusion index, as measured by the pulse oximeter, is a sensitive and reliable indicator of proper epidural catheter placement in obstetric patients, according to the results of studies performed at Harbor-UCLA Medical Center in Torrance, Calif. An increase in the perfusion index consistently reflected a functioning epidural catheter in patients undergoing Caesarean section, and also doubled in response to the administration of a standard epidural test dose in laboring parturients in two observational studies.Use of the perfusion index to confirm a functioning epidural is "a very powerful tool," Clinton Z. Kakazu, MD, told Anesthesiology News . He predicted its greatest use will be in laboring parturients.…”

Objective Assessment of Acute Pain

“…Both of the contributing measurements are thought to reflect the balance between sympathetic and parasympathetic tone, which is influenced by nociceptive stimulation. This non-invasive measurement has been shown to discriminate noxious stimuli under anesthesia [23]. In the post-operative setting however, it demonstrates only moderate sensitivity and specificity in identifying moderate to severe pain [24,25].…”
