Neonatal intubation: what are we doing?

: How and when the forces are applied during neonatal intubation are currently unknown. This study investigated the pattern of the applied forces by using sensorized laryngoscopes during the intubation process in a neonatal manikin. Nine users of direct laryngoscope and nine users of straight-blade video laryngoscope were included in a neonatal manikin study. During each procedure, relevant forces were measured using a force epiglottis sensor that was placed on the distal surface of the blade. The pattern of the applied forces could be divided into three sections. With the direct laryngoscope, the first section showed either a quick rise of the force or a discontinuous rise with several peaks; after reaching the maximum force, there was a sort of plateau followed by a quick drop of the applied forces. With the video laryngoscope, the first section showed a quick rise of the force; after reaching the maximum force, there was an irregular and heterogeneous plateau, followed by heterogeneous decreases of the applied forces. Moreover, less forces were recorded when using the video laryngoscope.    Conclusions: This neonatal manikin study identified three sections in the diagram of the forces applied during intubation, which likely mirrored the three main phases of intubation. Overall, the pattern of each section showed some differences in relation to the laryngoscope (direct or video) that was used during the procedure. These findings may provide useful insights for improving the understanding of the procedure. What is Known: • Neonatal intubation is a life-saving procedure that requires a skilled operator and may cause direct trauma to the tissues and precipitate adverse reactions. • Intubation with a videolaryngoscope requires less force than with a direct laryngoscope, but how and when the forces are applied during the whole neonatal intubation procedure are currently unknown. What is New: • Forces applied to the epiglottis during intubation can be divided into three sections: (i) an initial increase, (ii) a sort of plateau, and (iii) a decrease. • The pattern of each section shows some differences in relation to the laryngoscope (direct or videolaryngoscope) that is used during the procedure

Applied forces with direct versus indirect laryngoscopy in neonatal intubation: a randomized crossover mannequin study

Purpose: In adult mannequins, videolaryngoscopy improves glottic visualization with lower force applied to upper airway tissues and reduced task workload compared with direct laryngoscopy. This trial compared oropharyngeal applied forces and subjective workload during direct vs indirect (video) laryngoscopy in a neonatal mannequin. Methods: We conducted a randomized crossover trial of intubation with direct laryngoscopy, straight blade videolaryngoscopy, and hyperangulated videolaryngoscopy in a neonatal mannequin. Thirty neonatal/pediatric/anesthesiology consultants and residents participated. The primary outcome measure was the maximum peak force applied during intubation. Secondary outcome measures included the average peak force applied during intubation, time needed to intubate, and subjective workload. Results: Direct laryngoscopy median forces on the epiglottis were 8.2 N maximum peak and 6.8 N average peak. Straight blade videolaryngoscopy median forces were 4.7 N maximum peak and 3.6 N average peak. Hyperangulated videolaryngoscopy median forces were 2.8 N maximum peak and 2.1 N average peak. The differences were significant between direct laryngoscopy and straight blade videolaryngoscopy, and between direct laryngoscopy and hyperangulated videolaryngoscopy. Significant differences were also found in the top 10th percentile forces on the epiglottis and palate, but not in the median forces on the palate. Time to intubation and subjective workload were comparable with videolaryngoscopy vs direct laryngoscopy. Conclusions: The lower force applied during videolaryngoscopy in a neonatal mannequin model suggests a possible benefit in reducing potential patient harm during intubation, but the clinical implications require assessment in future studies.

Impact of a quality improvement intervention on neonatal mortality in a regional hospital in Burkina Faso

The neonatal period is the most vulnerable time in terms of a child's survival, with mortality during this period accounting for approximately half of the deaths before the age of 5 years. The Neonatal Essential Survival Technology (NEST) project is a program aiming to reduce mortality by improving the quality of neonatal care in sub-Saharan Africa. This study presents the evaluation of the first phase of the NEST intervention program at Saint Camille Hospital Ouagadougou (HOSCO), Burkina Faso, in terms of the reduction in neonatal mortality.This is a retrospective analysis, based on "pre-intervention" data collected in 2015, and "post-intervention" data collected in 2018, including all infants admitted to the neonatal unit of HOSCO. The intervention period (2016 and 2017) comprised a structured quality improvement process conducted by a multidisciplinary working group that focused on improving infrastructure, equipment, training and use of clinical protocols, team working within the neonatal unit and with other hospital departments, and communication with referring healthcare facilities. Mortality data were compared pre- vs. post-intervention using a logistic regression model.The analysis included 1427 infants in the pre-intervention period, and 819 post-intervention. In both time periods, more than 75% of admissions were infants with low birth weight, and nearly 50% were very low birth weight. Post-intervention, while there was a decrease in overall admission, the proportion of multiple births increased from 20% to 24% (The first phase of the NEST quality improvement program was associated with a decrease in mortality in outborn infants admitted to the neonatal unit at HOSCO. Long-term assessment is expected to provide a more comprehensive evaluation of the program in a low-income setting

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

Meconium Aspiration Syndrome: A Narrative Review

none6Meconium aspiration syndrome is a clinical condition characterized by respiratory failure occurring in neonates born through meconium-stained amniotic fluid. Worldwide, the incidence has declined in developed countries thanks to improved obstetric practices and perinatal care while challenges persist in developing countries. Despite the improved survival rate over the last decades, long-term morbidity among survivors remains a major concern. Since the 1960s, relevant changes have occurred in the perinatal and postnatal management of such patients but the most appropriate approach is still a matter of debate. This review offers an updated overview of the epidemiology, etiopathogenesis, diagnosis, management and prognosis of infants with meconium aspiration syndrome.noneMonfredini, Chiara; Cavallin, Francesco; Villani, Paolo Ernesto; Paterlini, Giuseppe; Allais, Benedetta; Trevisanuto, DanieleMonfredini, Chiara; Cavallin, Francesco; Villani, Paolo Ernesto; Paterlini, Giuseppe; Allais, Benedetta; Trevisanuto, Daniel

Device positioning with LISA vs. INSURE: a crossover randomized controlled manikin trial

Objective We aimed to compare time of device positioning, success of procedure and operator's opinion with LISA vs. INSURE in a manikin simulating an extremely low birthweight infant. Methods A randomized controlled crossover (AB/BA) trial of surfactant administration with LISA vs. INSURE in a preterm manikin. Forty-two tertiary hospital consultants and pediatric residents with previous experience with LISA and INSURE participated. The primary outcome measure was the time of device positioning. The secondary outcome measures were: success of the first attempt, number of attempts, correct depth, and participant's opinion on difficulty in using the device. Results Median time of device positioning was shorter with LISA vs. INSURE (median difference -8 s, 95% confidence interval -16 to -1 s; p = .04). Success at first attempt was 35/40 with LISA (83%) and 31/40 with INSURE (74%) (p = .42). Median number of attempts was 1 (IQR 1-1) with LISA and 1 (IQR 1-2) with INSURE (p = .08). Correct depth was achieved in 30/40 with LISA (71%) and 37/40 with INSURE (88%) (p = .12). Participants found LISA easier to insert in the trachea (p = .002) but INSURE easier to place at the correct depth (p = .008). Handling the device (p = .43), visualizing the glottis (p = .17) and overall difficulty in using the device (p = .13) were not statistically different. Conclusions In a preterm manikin model, positioning a thin catheter (LISA) was quicker and easier than a tracheal tube (INSURE), but the magnitude of the difference was unlikely to be clinically relevant and the tracheal tube was easier to place at the correct depth.

Thermal servo-controlled systems in the management of VLBW infants at birth: A systematic review

BackgroundThermal management of the newborn at birth remains an actual challenge. This systematic review aimed to summarize current evidence on the use of thermal servo-controlled systems during stabilization of preterm and VLBW infants immediately at birth. MethodsA comprehensive search was conducted including MEDLINE/Pubmed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database through December 2021. PRISMA guidelines were followed. Risk of bias was appraised using Cochrane RoB2 and Risk Of Bias In Non-Randomized Studies of Interventions (ROBIN-I) tools, and certainty of evidence using GRADE framework. ResultsOne randomized controlled trial and one observational study were included. Some aspects precluded the feasibility of a meaningful meta-analysis; hence, a qualitative review was conducted. Risk of bias was low in the trial and serious in the observational study. In the trial, the servo-controlled system did not affect normothermia (36.5-37.5 degrees C) but was associated with increased mild hypothermia (from 22.2 to 32.9%). In the observational study, normothermia (36-38 degrees C) increased after the introduction of the servo-controlled system and the extension to larger VLBW infants. ConclusionOverall, this review found very limited information on the use of thermal servo-controlled systems during stabilization of preterm and VLBW infants immediately at birth. Further research is needed to investigate the opportunity of including such approach in the neonatal thermal management in delivery room. RegistrationPROSPERO (CRD42022309323)
