Abstract
OBJECTIVE This article describes the results of a study investigating the sensitivity and specificity of the Newborn Infant Parasympathetic Evaluation (NIPE) index for detecting the physiological changes resulting from nociception in painful procedures in very low birth weight (VLBW) infants. STUDY DESIGN A prospective observational study was carried on of 44 newborns at 23 to 32 weeks' gestational age. The sensitivity and specificity of the NIPE index are analyzed using a receiver operating characteristic curve. Most of the painful procedures performed were skin-lancing and venipunctures. Nonpainful procedures consist of no intervention, with an interval of at least 1 hour with painful procedures in each newborn. RESULTS The accuracy of the NIPE index to diagnose mild nociceptive stimulation in VLBW newborns is 73.2%. CONCLUSION The NIPE index is a useful technique for assessing nociceptive stimulation in newborns, presenting less observer-dependent variability than other pain assessment scales. KEY POINTS · The NIPE index offers an objective assessment of pain.. · Moderate-high sensitivity of the NIPE index in the evaluation of pain in premature newborns.. · Painful procedures in VLBW newborns are reflected as a decrease in the NIPE score..

Abstract
Surgical pleth index (SPI) monitoring is a representative, objective nociception-monitoring device that measures nociception using photoplethysmographic signals. It is easy to apply to patients and the numerical calculation formula is intuitively easy to understand; therefore, its clinical interpretation is simple. Several studies have demonstrated its efficacy and utility. Compared with hemodynamic parameters, the SPI can detect the degree of nociception during surgery under general anesthesia with greater accuracy, and therefore can provide better guidance for the administration of various opioids, including remifentanil, fentanyl, and sufentanil. Indeed, SPI-guided analgesia is associated with lower intraoperative opioid consumption, faster patient recovery, and comparable or lower levels of postoperative pain and rates of adverse events compared with conventional analgesia. In addition, SPI monitoring allows for the degree of postoperative pain and analgesic requirements to be predicted through the SPI values immediately before patient arousal. However, because patient age, effective circulating volume, position, concomitant medication and anesthetic regimen and level of consciousness may be confounding factors in SPI monitoring, clinicians must be careful when interpreting SPI values. In addition, as SPI values can differ depending on anesthetic and analgesic regimens and the underlying disease, an awareness of the effects of these variables with an understanding of the advantages and disadvantages of SPI monitoring compared to other nociception monitoring devices is essential. Therefore, this review aimed to help clinicians perform optimal SPI-guided analgesia and to assist with the establishment of future research designs through clarifying current usefulness and limitations of SPI monitoring in perioperative pain management.

Abstract
BACKGROUND Pain assessment in the pediatric intensive care unit (PICU) is complex, specifically for children receiving mechanical ventilation who require neuromuscular blockade (NMB). No valid pain assessment method exists for this population. Guidelines are limited to using physiologic variables; it remains unknown how nurses are assessing and managing pain for this population in practice. OBJECTIVES To describe how PICU nurses are assessing and managing pain for children who require NMB. METHODS A cross-sectional quantitative design was used with an electronic survey. Nurses were asked to respond to 4 written vignettes depicting a child who required NMB and had a painful procedure, physiologic cues, both, or neither. RESULTS A total of 107 PICU nurses answered the survey. Nurses primarily used behavioral assessment scales (61.0%) to assess the child's pain. All nurses reported that physiologic variables are either moderately or extremely important, and 27.3% of nurses used the phrase "assume pain present" formally at their organization. When physiologic cues were present, the odds of a nurse intervening with a pain intervention were 23.3 times (95% CI, 11.39-53.92; P < .001) higher than when such cues were absent. CONCLUSIONS These results demonstrate variation in how nurses assess pain for a child who requires NMB. The focus remains on behavioral assessment scales, which are not valid for this population. When intervening with a pain intervention, nurses relied on physiologic variables. Decision support tools to aid nurses in conducting an effective pain assessment and subsequent management need to be created.

Abstract
The objective was to evaluate the effectiveness of the erector spinae plane block (ESP-block) as a component of perioperative analgesia in endovideosurgical hernioplasty of inguinal hernias.Materials and methods. The study included 70 patients who underwent endovideosurgical plastic surgery of inguinal hernias. All patients randomly divided into the main (n=32) and control (n=38) groups, were given general combined anesthesia. In the main group, it was supplemented with the ESP-block, which was performed with ropivacaine at the L1 level. Intraoperatively, fentanyl was used for analgesia. The indication for its introduction was an increase in the Surgical Pleth Index (SPI) of more than 50. In the early postoperative period, ketoprofen and tramadol were used for analgesia, which were administered with the development of moderate and high intensity of the pain. The effectiveness of the ESP-block was evaluated by comparing the total doses of analgesic drugs that were required for analgesia during surgery and in the early postoperative period in patients of both groups.Results. In the main group, the total doses of fentanyl and ketoprofen were statistically significantly lower compared to the control group (p<0.01). After surgery, tramadol was used only in patients of the control group. In some patients of the main group who required analgesia in the early postoperative period (n=15), the pain syndrome developed only 12 hours after the end of the surgery. Their intraoperative need for fentanyl did not differ from other patients of the main group (p>0.05).Conclusion. In endovideosurgical hernioplasty of inguinal hernias, the use of the ESP-block as part of multimodal analgesia contributes to achieving a good level of analgesia both intra- and in the early postoperative period.

Effect of surgical pleth index-guided remifentanil administration on perioperative outcomes in elderly patients: a prospective randomized controlled trial. BMC Anesthesiol 2023; 23:57.

Abstract
BACKGROUND During general anesthesia, the surgical pleth index (SPI) monitors nociception. The evidence of SPI in the elderly remains scarce. We aimed to investigate whether there is a difference in perioperative outcomes following intraoperative opioid administration according to the surgical pleth index (SPI) value versus hemodynamic parameters (heart rate or blood pressure) in elderly patients. METHODS Patients aged 65-90 years who underwent laparoscopic colorectal cancer surgery under sevoflurane/remifentanil anesthesia were randomized to receive remifentanil guided by SPI (SPI group) or conventional clinical judgment based on hemodynamic parameters (conventional group). The primary endpoint was intraoperative remifentanil consumption. Secondary endpoints were intraoperative hemodynamic instability, pain score, fentanyl consumption and delirium in the post-anesthesia care unit (PACU), and perioperative changes in interleukin-6 and natural killer (NK) cell activity. RESULTS Seventy-five patients (38, SPI; 37, conventional) were included in the study. The SPI group consumed significantly more remifentanil intraoperatively than the conventional group (mean ± SD, 0.13 ± 0.05 vs. 0.06 ± 0.04 μg/kg/min, P < 0.001). Intraoperative hypertension and tachycardia were more common in the conventional group than in the SPI group. Pain score in the PACU (P = 0.013) and the incidence of delirium in the PACU were significantly lower in the SPI group than the conventional group (5.2% vs. 24.3%, P = 0.02). There was no significant difference in NK cell activity and interleukin-6 level. CONCLUSIONS In the elderly patients, SPI-guided analgesia provided appropriate analgesia with sufficient intraoperative remifentanil consumption, lower incidence of hypertension/ tachycardia events, and a lower incidence of delirium in the PACU than the conventional analgesia. However, SPI-guided analgesia may not prevent perioperative immune system deterioration. TRIAL REGISTRATION The randomized controlled trial was retrospectively registered in the UMIN Clinical Trials Registry (trial number: UMIN000048351; date of registration: 12/07/2022).

Abstract
The association between intraoperative nociception and increased patient's morbidity is well established. However, hemodynamic parameters, such as heart rate and blood pressure, may result in an inadequate monitor of nociception during surgery. Over the last two decades, different devices have been marketed to "reliably" detect intraoperative nociception. Since the direct measure of nociception is impractical during surgery, these monitors measures nociception surrogates such as sympathetic and parasympathetic nervous systems responses (heart rate variability, pupillometry, skin conductance), electroencephalographic changes, and muscular reflex arc. Each monitor carries its own advantages and disadvantages. The manuscript aims to give an overview of the most up-to-date information available in the literature on current nociceptor monitors available in clinical practice, with particular focus on their applications in pediatrics.

Cholinesterase activity in serum during general anesthesia in patients with or without vascular disease. Sci Rep 2021; 11:16687. [PMID: 34404888 PMCID: PMC8371088 DOI: 10.1038/s41598-021-96251-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 08/06/2021] [Indexed: 11/08/2022] Open
Abstract
Maintaining hemodynamic stability during the induction and maintenance of anesthesia is one of the challenges of the anesthesiologist. Patients with vascular disease are at increased risk of instability due to imbalance between the sympathetic and parasympathetic parts of the autonomic nervous system, a balance accessible by serum cholinesterase activity. We aim to characterize the dynamics of cholinesterase activity in patients undergoing general anesthesia (GA) and surgery. This was a prospective study of 57 patients undergoing ambulatory or vascular surgery under GA. Cholinesterase activity was measured before the induction of anesthesia, after 15 min and at the end of surgery by calculating the capacity of serum acetylcholinesterase (AChE) and butyrylcholinesterase to hydrolyze AcetylThioCholine. Data on atherosclerotic disease, anesthesia management were analyzed. Both AChE and total cholinergic status (CS) decreased significantly after GA induction at 15 min and even more so by the end of surgery. Vascular surgery patients had lower baseline cholinesterase activity compared to ambulatory surgery patients. Patients requiring intraoperative administration of phenylephrine for hemodynamic support (21.1%) had a significantly lower level of AChE and CS compared to untreated patients. Our findings serve as a mirror to the sympathetic/parasympathetic imbalance during GA, with a marked decrease in the parasympathetic tone. The data of a subgroup analysis show a correlation between low cholinesterase activity and an increase in the need for hemodynamic support.
