Pilot study of an interprofessional pediatric mechanical ventilation educational initiative in two intensive care units.

INTRODUCTION: Inappropriate ventilator settings, non-adherence to a lung-protective ventilation strategy, and inadequate patient monitoring during mechanical ventilation can potentially expose critically ill children to additional risks. We set out to improve team theoretical knowledge and practical skills regarding pediatric mechanical ventilation and to increase compliance with treatment goals. METHODS: An educational initiative was conducted from August 2019 to July 2021 in a neonatal and pediatric intensive care unit of the University Children's Hospital, Hamburg-Eppendorf, Germany. We tested baseline theoretical knowledge using a multiple choice theory test (TT) and practical skills using a practical skill test (PST), consisting of four sequential Objective Structured Clinical Examinations of physicians and nurses. We then implemented an educational bundle that included video self-training, checklists, pocket cards, and reevaluated team performance. Ventilators and monitor settings were randomly checked in all ventilated patients. We used a process control chart and a mixed-effects model to analyze the primary outcome. RESULTS: A total of 47 nurses and 20 physicians underwent assessment both before and after the implementation of the initiative using TT. Additionally, 34 nurses and 20 physicians were evaluated using the PST component of the initiative. The findings revealed a significant improvement in staff performance for both TT and PST (TT: 80% [confidence interval (CI): 77.2-82.9] vs. 86% [CI: 83.1-88.0]; PST: 73% [CI: 69.7-75.5] vs. 95% [CI: 93.8-97.1]). Additionally, there was a notable increase in self-confidence among participants, and compliance with mechanical ventilation treatment goals also saw a substantial rise, increasing from 87.8% to 94.5%. DISCUSSION: Implementing a pediatric mechanical ventilation education bundle improved theoretical knowledge and practical skills among interprofessional pediatric intensive care staff and increased treatment goal compliance in ventilated children.

Recommendations for endotracheal tube insertion depths in children.

BACKGROUND: Endotracheal tube (ETT) malposition is frequent in paediatric intubation. The current recommendations for ETT insertion depths are based on formulae that hold various limitations. This study aimed to develop age-based, weight-based and height-based curve charts and tables for ETT insertion depth recommendations in children. METHODS: In this retrospective single-centre study, we determined the individual optimal ETT insertion depths in paediatric patients by evaluating postintubation radiographic images. Age-based, weight-based and height-based ETT insertion depth recommendations were developed using regression analysis. We compared the insertion depths predicted by the models with previously published formulae. RESULTS: Intubations of 167 children (0-17.9 years) were analysed. Best-fit curves generated with logistic regression analysis revealed R2 values between 0.784 and 0.880. The insertion depths predicted by the models corresponded well with published age-based and height-based formulae. However, they demonstrated the unsuitability of weight-related linear formulae to predict ETT depth in children. CONCLUSION: The recommendations developed in this study facilitate a fast and accurate determination of recommended ETT insertion depths in children. Our recommendations provide greater accuracy than previously published formulae and demonstrate that weight-related linear formulae are unsuitable for predicting ETT depth in children.

Recommendations for Peripherally Inserted Central Catheter Insertion Depths in Neonates.

OBJECTIVE: Malposition of peripherally inserted central catheters (PICCs) is common. Recommendations for PICC insertion depths are scarce and comprise complex equations. This study aimed to develop diagrams and tables for the recommendation of PICC insertion depths in neonates based on anthropometric parameters. STUDY DESIGN: In this retrospective single-center study, the individual optimal PICC insertion depths were correlated with body weight, length, and head circumference. Using linear regression analysis, line charts and tables for the recommendation of PICC insertion depth were generated and compared with previously published recommendations. RESULT: PICC insertion depths of 204 infants (gestational age at PICC installation: 24.0-44.9 weeks) with 131 (64%) PICC in the upper extremities and 73 (36%) in the lower extremities were analyzed. Linear logistic regression models revealed R2 values between 0.387 and 0.884. CONCLUSION: The charts and table developed in this study enable a fast and accurate determination of recommended PICC insertion depths in neonates.

Teaching fiberoptic-assisted tracheoscopy in very low birth weight infants: A randomized controlled simulator study.

Objective: We developed a fiberoptic-assisted tracheoscopy (FAST) method to avoid direct laryngoscopy during surfactant replacement therapy and compared two training approaches on a very low birth weight (VLBW) infant simulator. Design: This prospective randomized controlled study was conducted at the Department of Neonatology and Pediatric Intensive Care Medicine of the University Medical Center Hamburg-Eppendorf, Germany. Participants: We recruited physicians, trainees, students, and nurses without prior experience in endoscopic techniques. Interventions: Participants were assigned randomly to a group that received instructions according to Peyton's Four-Step Approach and a control group that received standard bedside teaching only. Main outcome measures: Primary endpoints were the total and the component times required to place the bronchoscope and the method success. Results: We recruited 186 participants. Compared with the control group, the Peyton group had a lower mean (±standard deviation) FAST completion time (33.2 ± 27.5 s vs. 79.5 ± 47.9 s, p < 0.001; d = 1.12) and a higher FAST success rate (95% vs. 84%, p = 0.036, V = 0.18). Conclusion: After standardized training, the vast majority of novices completed FAST successfully. Peyton's four-step approach resulted in faster and more successful performance than standardized training.

Recommendations for nasotracheal tube insertion depths in neonates.

Background: Endotracheal tube (ETT) malposition is common in neonatal intubation. Recommendations for ETT insertion depths predominantly address orotracheal intubation. The aim of this study was to develop gestational age-, weight-, and length-based curve charts and tables for nasotracheal ETT insertion depth recommendations in neonates. Method: In this retrospective single-center study, the individual optimal ETT insertion depths in neonates were determined by evaluating postintubation radiographic images. Gestational age-, weight-, and length-based best-fit curves and tables were generated using regression analysis to calculate related ETT insertion depths. The insertion depths predicted by the models were compared with previously published recommendations. Results: We analyzed intubations of 178 neonates (gestational age range at intubation: 23.7-43.0 weeks). Applying sigmoidal logistic regression models, curves, and tables revealed R 2 values between 0.766 and 0.837. The insertion depths predicted by the models revealed certain deviations when compared with four previously published recommendations for nasotracheal ETT depth estimation in neonates. Conclusion: The charts and tables developed in this study enable a fast and accurate determination of recommended nasotracheal ETT insertion depths in neonates.

The Impact of a Dedicated Sedation Team on the Incidence of Complications in Pediatric Procedural Analgosedation.

The number of pediatric procedural sedations for diagnostic and minor therapeutic procedures performed outside the operating room has increased. Therefore, we established a specialized interdisciplinary team of pediatric anesthesiologists and intensivists (Children's Analgosedation Team, CAST) at our tertiary-care university hospital and retrospectively analyzed the first year after implementation of the CAST. Within one year, 784 procedural sedations were performed by the CAST; 12.2% of the patients were infants <1 year, 41.9% of the patients were classified as American Society of Anesthesiologists (ASA) grade III or IV. Most children received propofol (79%) and, for painful procedures, additional esketamine (48%). Adverse events occurred in 51 patients (6.5%), with a lack of professional experience (OR 0.60; 95% CI 0.42−0.81) and increased propofol dosage (OR 1.33; 95% CI 1.17−1.55) being significant predictors. Overall, the CAST enabled safe and effective procedural sedation in children outside the operating room.

Therapeutic Management of COVID-19 in a Pediatric Patient with Neurodegenerative CLN2 Disease and ICV-Enzyme Replacement Therapy: A Case Report.

The 12 years old male patient presented here suffers from neuronal ceroid lipofuscinoses 2 (CLN2) (MIM# 204500) and receives intracerebroventricular enzyme replacement therapy (ICV-ERT) every 14 days. After the emergence of the coronavirus disease 2019 (COVID-19) pandemic, routine care of children and adolescents with rare chronic diseases has become challenging. Although, in general, children do not develop severe COVID-19, when severe acute respiratory syndrome coronavirus 2 infection was detected by polymerase chain reaction-screening examination in our CLN2 patient before hospital admission for ICV-ERT, he was regarded to be at risk. Upon diagnosis, the patient developed respiratory deterioration symptoms and was admitted to our pediatric intensive care unit to receive oxygen, remdesivir, and steroids. As far as we know, this is the first CLN2 patient receiving intraventricular enzyme therapy with COVID-19 who required intensive care treatment and specific therapy.

Thyroid function, thyroid antibodies and early postnatal development in neonates of mothers with thyroid disorders.

BACKGROUND: Thyroid dysfunction during pregnancy is relatively common and can cause obstetric complications and significantly influence fetal development. AIMS: We aimed to evaluate postnatal clinical and laboratory characteristics in the first days of life in infants born to mothers with a thyroid disorder. STUDY DESIGN AND SUBJECTS: We conducted a retrospective single-center study with neonates born between January 2010 and May 2020. Early laboratory parameters and clinical findings in neonates of mothers with different maternal thyroid disorders were analysed. RESULTS: We included 314 newborns of mothers with Hashimoto's thyroiditis, 171 with non-Hashimoto's hypothyroidism, 42 with Graves' disease, 12 with non-Graves' hyperthyroidism, and 190 neonates born to mothers without thyroid dysfunction. No demographic, clinical, and laboratory differences were observed between neonates from mothers with a thyroid disorder and healthy mothers. FT3 and fT4 correlated positively with gestational age (p < 0.001; p < 0.001) and negatively with maximum postnatal weight loss (p = 0.043; p < 0.001). High fT3 values were associated with lower maximum bilirubin levels (p = 0.020). CONCLUSION: Despite an increased morbidity risk due to the transplacental exposure to maternal antibodies, most neonates born to mothers with thyroid disorders show normal postnatal development and thyroid function tests during the first days of life.

Estimation of Optimal Nasotracheal Tube Insertion Depth in Neonates Based on Fetal Biometric Measurements.

BACKGROUND: Current recommendations for neonatal endotracheal tube (ETT) insertion depths require the knowledge of anthropometric measurements, which are not immediately available in the delivery room setting. OBJECTIVE: This study aimed to develop recommendations based on prenatally available fetal biometric measurements. METHODS: In this retrospective study, the optimal ETT depths for nasotracheal insertion were correlated with fetal demographic and biometric data. Using linear regression analysis, diagrams with best-fit lines and tables for the recommendation of ETT insertion depth based on the prenatally available data were generated. RESULTS: We analyzed optimal nasotracheal ETT insertion depth in 98 neonates (gestational age range: 23.7-42.0 weeks). Linear regression analysis revealed high correlations between fetal measurements and the optimal ETT insertion depth (R2 = 0.712-0.837). CONCLUSION: We provide recommendations for neonatal nasotracheal ETT insertion depths based on prenatally available data with the potential to facilitate rapid and accurate intubation of neonates.

Mucha-Habermann disease: a pediatric case report and proposal of a risk score.

Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare inflammatory dermatological disease. A case of a 13-year-old boy with FUMHD possibly triggered by mycoplasma infection is presented. Based on FUMHD cases identified in a MEDLINE literature search, demographic, treatment, and outcome data were analyzed. An FUMHD mortality risk score is proposed based on the likelihood ratios of risk factors for a fatal outcome. Our FUMHD case had marked leukopenia and thrombocytopenia at admission. He recovered without systemic immunosuppressive treatment. Literature review revealed 119 FUMHD cases. Overall lethality was 14/119 (12%, CI 6-17%), and lethality in children was lower (1/54, 2%, CI 0-6%) compared to adults (13/65, 20%, CI 11-31%). Risk factors for a fatal outcome (likelihood ratio; P) were sepsis (24.97, P < 0.001), adult vs. pediatric patient age (11.19; P = 0.001), systemic involvement (19.97, P < 0.001), and mucosal involvement (4.58; P = 0.032). The proposed FUMHD mortality risk score = Age/10 + 4 + 4 (if systemic involvement) + 1 (if mucosal involvement) was discriminative (sensitivity 93%, specificity 77%). In FUMHD, immune-suppressive treatment intensity should be balanced against the mortality risk, as infectious complications are a frequent cause of death.

Markers of neutrophil activation and extracellular trap formation predict appendicitis.

BACKGROUND: Although appendicitis is one of the most frequently occurring pediatric surgery emergencies, current biomarkers for diagnosis are unspecific and have low predictive values. Neutrophils are an essential component of the innate immune system involved during appendicitis. Thus, the current study aimed to evaluate neutrophils and their activation markers in a prospective cohort study. METHODS: The study population included all children with acute abdominal pain who presented to the pediatric surgery department of 2 large clinics between July 2018 and December 2019. All enrolled subjects underwent blood sample collection with an assessment of white blood cell count, C-reactive protein, cell-free DNA, neutrophil elastase, myeloperoxidase, and citrullinated histone H3. If an appendectomy was performed, the appendix was stained for myeloperoxidase, neutrophil elastase, and citrullinated histone H3 using immunofluorescence. RESULTS: In total, 198 subjects were included in the study, of whom 133 had histological verified appendicitis. In those with appendicitis, white blood cell count and C-reactive protein showed a moderate diagnostic value for (noncomplicated and complicated) appendicitis. However, cell-free DNA (area under the curve .87) and citrullinated histone H3 (area under the curve .88) demonstrated excellent predictive power for appendicitis. Most notably, citrullinated histone H3 was able to distinguish (1) noncomplicated from complicated appendicitis, and (2) predict patient outcome. Moreover, the examined biomarkers appear to reflect tissue expression and disease severity. CONCLUSION: Markers of neutrophil activation and extracellular trap formation are excellent biomarkers for appendicitis. In particular, citrullinated histone H3 may be used to identify children with an increased risk of developing complications after appendicitis.

Anatomic accuracy, physiologic characteristics, and fidelity of very low birth weight infant airway simulators.

BACKGROUND: Medical simulation training requires realistic simulators with high fidelity. This prospective multi-center study investigated anatomic precision, physiologic characteristics, and fidelity of four commercially available very low birth weight infant simulators. METHODS: We measured airway angles and distances in the simulators Premature AirwayPaul (SIMCharacters), Premature Anne (Laerdal Medical), Premie HAL S2209 (Gaumard), and Preterm Baby (Lifecast Body Simulation) using computer tomography and compared these to human cadavers of premature stillbirths. The simulators' physiologic characteristics were tested, and highly experienced experts rated their physical and functional fidelity. RESULTS: The airway angles corresponded to those of the reference cadavers in three simulators. The nasal inlet to glottis distance and the mouth aperture to glottis distance were only accurate in one simulator. All simulators had airway resistances up to 20 times higher and compliances up to 19 times lower than published reference values. Fifty-six highly experienced experts gave three simulators (Premature AirwayPaul: 5.1 ± 1.0, Premature Anne 4.9 ± 1.1, Preterm Baby 5.0 ± 1.0) good overall ratings and one simulator (Premie HAL S2209: 2.8 ± 1.0) an unfavorable rating. CONCLUSION: The simulator physiology deviated significantly from preterm infants' reference values concerning resistance and compliance, potentially promoting a wrong ventilation technique. IMPACT: Very low birth weight infant simulators showed physiological properties far deviating from corresponding patient reference values. Only ventilation with very high peak pressure achieved tidal volumes in the simulators, as aimed at in very low birth weight infants, potentially promoting a wrong ventilation technique. Compared to very low birth weight infant cadavers, most tested simulators accurately reproduced the anatomic angular relationships, but their airway dimensions were relatively too large for the represented body. The more professional experience the experts had, the lower they rated the very low birth weight infant simulators.

Improved Less Invasive Surfactant Administration Success in Preterm Infants after Procedure Standardization.

Less invasive surfactant administration (LISA) has been introduced at our tertiary Level IV perinatal center since 2016 with an unsatisfactory success rate, which we attributed to an inconsistent, non-standardized approach and ambiguous patient inclusion criteria. This study aimed to improve the LISA success rate to at least 75% within 12 months by implementing a highly standardized LISA approach combined with team training. The Plan Do Study Act method of quality improvement was used for this initiative. Baseline assessment included a review of patient medical records 12 months before the intervention regarding patient characteristics, method success rate, respiratory, and adverse outcomes. A multi-professional team developed a standardized LISA approach and a training program including an educational film, checklists, pocket cards, and team briefings. Twenty-one preterm infants received LISA before and 24 after the intervention. The mean LISA success rate improved from 62% before the intervention to 92% (p = 0.029) after the intervention. Implementing a highly standardized LISA approach and multi-professional team training significantly improved the methods' success rate.

Iatrogenic Blood Loss in Very Low Birth Weight Infants and Transfusion of Packed Red Blood Cells in a Tertiary Care Neonatal Intensive Care Unit.

An adequate blood volume is important for neonatal adaptation. The study objective was to quantify the cumulative iatrogenic blood loss in very low birth weight (VLBW) infants by blood sampling and the necessity of packed red cell transfusions from birth to discharge from the hospital. In total, 132 consecutive VLBW infants were treated in 2019 and 2020 with a median birth weight of 1180 g (range 370-1495 g) and a median length of stay of 54 days (range 0-154 days) were included. During the initial four weeks of life, the median absolute amount of blood sampling was 16.5 mL (IQR 12.3-21.1 mL), sampling volume was different with 14.0 mL (IQR 12.1-16.2 mL) for non-transfused infants and 21.6 mL (IQR 17.5-29.4 mL) for transfused infants. During the entire length of stay, 31.8% of the patients had at least one transfusion. In a generalized logistic regression model, the cumulative amount of blood sampling (p < 0.01) and lower hematocrit at birth (p = 0.02) were independent predictors for the necessity of blood transfusion. Therefore, optimized patient blood management in VLBW neonates should include sparse blood sampling to avoid iatrogenic blood loss.

Impact of Propofol Bolus Administration on the Nociceptive Flexion Reflex Threshold and Bispectral Index in Children-A Case Series.

We analyzed the impact of propofol administration during continuous sedation and analgesia on the nociceptive flexion reflex threshold (NFRT) and Bispectral Index (BIS) in ventilated children. We examined patients who received propofol before planned endotracheal suctioning. Patients were clinically assessed using the modified Face, Legs, Activity, Cry, Consolability (mFLACC) scale and COMFORT-B (Comfort Behavior) scale. We continuously recorded the NFRT and BIS. We recorded 23 propofol administrations in eight patients with an average age of 8.6 ± 3.5 years. The median (minimum-maximum) scores for the mFLACC scale and COMFORT-B scale were 0 (0-5) and 6 (6-17), respectively, before the bolus. The administration of a weight-adjusted propofol bolus of 1.03 ± 0.31 mg/kg resulted in an increase in NFRT and burst-suppression ratio; BIS and electromyogram values decreased. Changes from baseline (95% CI) after propofol bolus administration were BIS -23.9 (-30.8 to -17.1), EMG -10.5 dB (-13.3 to -7.7), SR 14.8 % (5.6 to 24.0) and NFRT 13.6 mA (5.5 to 21.7). Further studies are needed to determine whether sedated children may benefit from objective pain and sedation monitoring with BIS and NFRT.

Fatal COVID-19 in a Child with Persistence of SARS-CoV-2 Despite Extensive Multidisciplinary Treatment: A Case Report.

Critical Coronavirus disease 2019 (COVID-19) developed in a 7-year-old girl with a history of dystrophy, microcephaly, and central hypothyroidism. Starting with gastrointestinal symptoms, the patient developed severe myocarditis followed by progressive multiple organ failure complicated by Pseudomonas aeruginosa bloodstream infection. Intensive care treatment consisting of invasive ventilation, drainage of pleural effusion, and high catecholamine therapy could not prevent the progression of heart failure, leading to the implantation of venoarterial extracorporeal life support (VA-ECLS) and additional left ventricle support catheter (Impella® pump). Continuous venovenous hemofiltration (CVVH) and extracorporeal hemadsorption therapy (CytoSorb®) were initiated. Whole exome sequencing revealed a mutation of unknown significance in DExH-BOX helicase 30 (DHX30), a gene encoding a RNA helicase. COVID-19 specific antiviral and immunomodulatory treatment did not lead to viral clearance or control of hyperinflammation resulting in the patient's death on extracorporeal life support-(ECLS)-day 20. This fatal case illustrates the potential severity of pediatric COVID-19 and suggests further evaluation of antiviral treatment strategies and vaccination programs for children.

Reference ranges for sphingosine-1-phosphate in neonates.

OBJECTIVES: Sphingosine-1-phosphate (S1P) is a signalling lipid involved in embryonic development, physiological homeostasis, and pathogenic processes in multiple organ systems. Disturbance of S1P homeostasis has been associated with various human diseases in which the immune response and vascular integrity are severely compromised. Up-to-date, no study has analyzed S1P levels in neonates. The objective of this study was to determine S1P serum concentrations in neonates and establish S1P reference ranges. METHODS: S1P levels in the umbilical cord blood of 460 term and preterm neonates were compared to a previously described cohort of healthy adult blood donors. S1P levels were further correlated with demographic characteristics, cellular sources of S1P, and inflammatory markers. RESULTS: The median S1P serum level in neonates was 1.70 µmol/L (IQR 1.41-1.97 µmol/L) and significantly higher than normal values reported in adults. S1P levels correlated positively with the number of red blood cells (p<0.001) and negatively with neutrophil precursors (p=0.028). CONCLUSIONS: Elevated S1P levels in neonates compared to adults possibly result from higher S1P content in its cellular sources due to the essential role of S1P during embryogenesis. Generated S1P ranges may be used as reference ranges for future studies in neonates.

[Effects of Obstetric Analgesia with Systemic Opioids on the Newborn - A Review]. / Auswirkungen geburtshilflicher Analgesie mit systemischen Opioiden auf das Neugeborene ­ eine Übersichtsarbeit.

INTRODUCTION: Three-quarters of all women receive analgesia during labor. There are regional and systemic analgesia procedures available. In this review, we investigate the impact of obstetric analgesia using systemic opioids on neonatal outcomes. METHODS: We searched the PubMed and Cochrane Library databases using the following search terms: "meptazinol", "meptide", "analgesia", "painkiller", "pain reliever", "obstetrics", "labor", "labour", "delivery", "neonate", "newborn", "child", "baby", "infant", "fetus", "fetal", "opioid" and "opiate" as well as performed an additional MeSH Terms search in PubMed. RESULTS: Of 355 potentially relevant studies, we included 23 studies in this review. The studies varied widely in quality, sample size, and outcome criteria. Neonatal outcome was often only a secondary endpoint. Rarely were significant differences related to neonatal outcome reported between the different systemic opioids or compared with control groups. Twelve studies compared neonatal APGAR scores between treatment groups, with ten (83%) of these studies showing no differences. DISCUSSION/OUTLOOK: In summary, we assess the evidence as limited and ambiguous as to whether systemic obstetric opioid therapy negatively affects the newborn. Studies regarding the long-term outcome of the newborns are lacking. A statement regarding the necessity of postnatal monitoring of newborns after maternal obstetric opioid therapy cannot be concluded. Further studies, ideally with a prospective study design and control group, should be considered.

Prediction of Nociception in Children Using the Nociceptive Flexion Reflex Threshold and the Bispectral Index-A Prospective Exploratory Observational Study.

OBJECTIVES: The prediction of patient responses to potentially painful stimuli remains a challenge in PICUs. We investigated the ability of the paintracker analgesia monitor (Dolosys GmbH, Berlin, Germany) measuring the nociceptive flexion reflex threshold, the cerebral sedation monitor bispectral index (Medtronic, Dublin, Ireland), the COMFORT Behavior, and the modified Face, Legs, Activity, Cry, Consolability Scale scores to predict patient responses following a noxious stimulus. DESIGN: Single-center prospective exploratory observational study. SETTING: Fourteen-bed multidisciplinary PICU at the University Children's Hospital, University Medical Center Hamburg Eppendorf, Germany. PATIENTS: Children on mechanical ventilation receiving analgesic and sedative medications. INTERVENTIONS: Noxious stimulation by way of endotracheal suctioning. MEASUREMENTS AND MAIN RESULTS: Two independent observers assessed modified Face, Legs, Activity, Cry, Consolability and COMFORT Behavior Scales scores during noxious stimulation (n = 59) in 26 patients. Vital signs were recorded immediately before and during noxious stimulation; bispectral index and nociceptive flexion reflex threshold were recorded continuously. Mean prestimulation bispectral index (55.5; CI, 44.2-66.9 vs 39.9; CI, 33.1-46.8; p = 0.007), and COMFORT Behavior values (9.5; CI, 9.2-13.2 vs 7.5; CI, 6.7-8.5; p = 0.023) were significantly higher in observations with a response than in those without a response. Prediction probability (Pk) values for patient responses were high when the bispectral index was used (Pk = 0.85) but only fair when the nociceptive flexion reflex threshold (Pk = 0.69) or COMFORT Behavior Scale score (Pk = 0.73) was used. A logistic mixed-effects model confirmed the bispectral index as a significant potential predictor of patient response (p = 0.007). CONCLUSIONS: In our sample of ventilated children in the PICU, bispectral index and nociceptive flexion reflex threshold provided good and fair prediction accuracy for patient responses to endotracheal suctioning.
