Unanticipated difficult airway after prolonged use of a laryngeal mask airway.

The laryngeal mask airway (LMA) is recognized as a safe alternative to endotracheal intubation for short-term airway maintenance. In this case report we present the case of a term neonate with upper airway obstruction which was managed with a deflated LMA for 7 consecutive days. Despite previous reports of extended LMA use in neonates without complications, this patient experienced significant pharyngeal mucosal injury and edema, leading to difficulty with subsequent intubation attempts.

Variability for Age at Successful Extubation in Infants with Congenital Diaphragmatic Hernia.

OBJECTIVE: The objective of this study was to characterize clinical factors associated with successful extubation in infants with congenital diaphragmatic hernia. STUDY DESIGN: Using the Children's Hospitals Neonatal Database, we identified infants with congenital diaphragmatic hernia from 2017 to 2020 at 32 centers. The main outcome was age in days at the time of successful extubation, defined as the patient remaining extubated for 7 consecutive days. Unadjusted Kaplan-Meier and multivariable Cox proportional hazards ratio equations were used to estimate associations between clinical factors and the main outcome. Observations occurred through 180 days after birth. RESULTS: There were 840 eligible neonates with a median gestational age of 38 weeks and birth weight of 3.0 kg. Among survivors (n = 693), the median age at successful extubation was 15 days (interquartile range [IQR]: 8-29 days, 95th percentile: 71 days). For nonsurvivors (n = 147), the median age at death was 21 days (IQR: 11-39 days, 95th percentile: 110 days). Center (adjusted hazards ratio: 0.22-15, P < .01), low birth weight, intrathoracic liver position, congenital heart disease, lower 5-minute Apgar score, lower pH upon admission to Children's Hospitals Neonatal Database center, and use of extracorporeal support were independently associated with older age at successful extubation. Tracheostomy was associated with multiple failed extubations. CONCLUSION: Our findings suggest that infants who have not successfully extubated by about 3 months of age may be candidates for tracheostomy with chronic mechanical ventilation or palliation. The variability of timing of successful extubation among our centers supports the development of practice guidelines after validating clinical criteria.

Cuffed versus uncuffed endotracheal tubes for neonates.

BACKGROUND: Endotracheal intubation is a commonly performed procedure in neonates, the risks of which are well-described. Some endotracheal tubes (ETT) are equipped with a cuff that can be inflated after insertion of the ETT in the airway to limit leak or aspiration. Cuffed ETTs have been shown in larger children and adults to reduce gas leak around the ETT, ETT exchange, accidental extubation, and exposure of healthcare workers to anesthetic gas during surgery. With improved understanding of neonatal airway anatomy and the widespread use of cuffed ETTs by anesthesiologists, the use of cuffed tubes is increasing in neonates. OBJECTIVES: To assess the benefits and harms of cuffed ETTs (inflated or non-inflated) compared to uncuffed ETTs for respiratory support in neonates. SEARCH METHODS: We searched CENTRAL, PubMed, and CINAHL on 20 August 2021; we also searched trial registers and checked reference lists to identify additional studies. SELECTION CRITERIA: We included randomized controlled trials (RCTs), quasi-RCTs, and cluster-randomized trials comparing cuffed (inflated and non-inflated) versus uncuffed ETTs in newborns. We sought to compare 1. inflated, cuffed versus uncuffed ETT; 2. non-inflated, cuffed versus uncuffed ETT; and 3. inflated, cuffed versus non-inflated, cuffed ETT. DATA COLLECTION AND ANALYSIS: We used the standard methods of Cochrane Neonatal. Two review authors independently assessed studies identified by the search strategy for inclusion, extracted data, and assessed risk of bias. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: We identified one eligible RCT for inclusion that compared the use of cuffed (inflated if ETT leak greater than 20% with cuff pressure 20 cm H2O or less) versus uncuffed ETT. The author provided a spreadsheet with individual data. Among 76 infants in the original manuscript, 69 met the inclusion and exclusion criteria for this Cochrane Review. We found possible bias due to lack of blinding and other bias. We are very uncertain about frequency of postextubation stridor, because the confidence intervals (CI) of the risk ratio (RR) were very wide (RR 1.36, 95% CI 0.35 to 5.25; risk difference (RD) 0.03, -0.11 to 0.18; 1 study, 69 participants; very low-certainty evidence). No neonate was diagnosed with postextubation subglottic stenosis; however, endoscopy was not available to confirm the clinical diagnosis. We are very uncertain about reintubation for stridor or subglottic stenosis because the CIs of the RR were very wide (RR 0.27, 95% CI 0.01 to 6.49; RD -0.03, 95% CI -0.11 to 0.05; 1 study, 69 participants; very low-certainty evidence). No neonate had surgical intervention (e.g. endoscopic balloon dilation, cricoid split, tracheostomy) for stridor or subglottic stenosis (1 study, 69 participants). Neonates randomized to cuffed ETT may be less likely to have a reintubation for any reason (RR 0.06, 95% CI 0.01 to 0.45; RD -0.39, 95% CI -0.57 to -0.21; number needed to treat for an additional beneficial outcome 3, 95% CI 2 to 5; 1 study, 69 participants; very low-certainty evidence). We are very uncertain about accidental extubation because the CIs of the RR were wide (RR 0.82, 95% CI 0.12 to 5.46; RD -0.01, 95% CI -0.12 to 0.10; 1 study, 69 participants; very low-certainty evidence). We are very uncertain about all-cause mortality during initial hospitalization because the CIs of the RR were extremely wide (RR 2.46, 95% CI 0.10 to 58.39; RD 0.03, 95% CI -0.05 to 0.10; 1 study, 69 participants; very low-certainty evidence). There is one ongoing trial. We classified two studies as awaiting classification because outcome data were not reported separately for newborns and older infants. AUTHORS' CONCLUSIONS: Evidence for comparing cuffed versus uncuffed ETTs in neonates is limited by a small number of babies in a single RCT with possible bias. There is very low certainty evidence for all outcomes of this review. CIs of the estimate for postextubation stridor were wide. No neonate had clinical evidence for subglottic stenosis; however, endoscopy results were not available to assess the anatomy. Additional RCTs are necessary to evaluate the benefits and harms of cuffed ETTs (inflated and non-inflated) in the neonatal population. These studies must include neonates and be conducted both for short-term use (in the setting of the operating room) and chronic use (in the setting of chronic lung disease) of cuffed ETTs.

Teaching NICU Fellows How to Relay Difficult News Using a Simulation-Based Curriculum: Does Comfort Lead to Competence?

PROBLEM: Neonatal Intensive Care Unit (NICU) clinicians must frequently relay difficult news to patient families, and the need for formal training for NICU trainees to develop this skill has been established. Although previous studies have shown improved trainee self-efficacy and comfort in handling difficult conversations after formal communication training, it remains unclear whether these interventions lead to improved objectively assessed short-term and long-term performance. INTERVENTION: A simulation-based intervention emphasizing the SPIKES protocol for delivery of bad news was implemented for 15 fellows in the 3-year Baylor College of Medicine Neonatal-Perinatal Medicine fellowship program in the 2013-2014 academic year. Simulations involved video-recorded encounters between each fellow and a standardized parent (SP) involving communication of difficult news. Each fellow was evaluated before (preintervention), immediately after (postintervention), and 3-4 months after the intervention (follow-up) with an (a) evaluation of video-recorded sessions by two expert raters blinded to the timing of the encounter (blinded rater evaluation [BRE]), (b) Self-Assessment Questionnaire, (c) Content Test evaluating knowledge of taught concepts, and (d) SP evaluation (SPE). CONTEXT: The 1st- and 2nd/3rd-year fellows participated in the study at separate times in the academic year to accommodate their schedules. First-year fellows had had more prior communication training and less NICU clinical experience than the 2nd/3rd-year fellows at the time of their intervention. OUTCOME: Although all fellows displayed improved Self-Assessment and Content Test scores at postintervention with retention at the follow-up assessment, the BREs showed no statistically significant improvement in postintervention scores and showed a decline in follow-up scores. First-year fellows had higher BRE postintervention scores than the senior fellows. SPEs showed no difference in scores at all 3 assessment stages. LESSONS LEARNED: As previously described in the literature, trainee self-efficacy and knowledge may improve in the short term and long term with a simulation-based curriculum in communication of difficult news. However, these results may be inconsistent with those of objective evaluations by expert raters and standardized parents. The impact of the curriculum may be heightened if it reinforces previously learned skills, but the effect may wane over time if not reinforced frequently with additional formal training or in the clinical setting. The results of this study highlight the importance of objective assessments in evaluating the utility of a simulation-based communication curriculum and the need for longitudinal curricula to promote retention of the concepts and skills being taught.

Syngnathia and obstructive apnea in a case of popliteal pterygium syndrome.

UNLABELLED: We describe an infant with popliteal pterygia, syngnathia, cleft lip and palate, and retrognathia diagnosed with popliteal pterygium syndrome (PPS). The neonatal course was complicated by severe obstructive apnea necessitating tracheostomy. CONCLUSION: This report illustrates the potential for airway compromise in PPS patients and the need for thorough neonatal airway assessment.

A clinical consensus guideline for nutrition in infants with congenital diaphragmatic hernia from birth through discharge.

OBJECTIVE: To develop a consensus guideline to meet nutritional challenges faced by infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: The CDH Focus Group utilized a modified Delphi method to develop these clinical consensus guidelines (CCG). Topic leaders drafted recommendations after literature review and group discussion. Each recommendation was sent to focus group members via a REDCap survey tool, and members scored on a Likert scale of 0-100. A score of > 85 with no more than 25% outliers was designated a priori as demonstrating consensus among the group. RESULTS: In the first survey 24/25 recommendations received a median score > 90 and after discussion and second round of surveys all 25 recommendations received a median score of 100. CONCLUSIONS: We present a consensus evidence-based framework for managing parenteral and enteral nutrition, somatic growth, gastroesophageal reflux disease, chylothorax, and long-term follow-up of infants with CDH.
