RESUMO
OBJECTIVE: To assess whether video laryngoscopy (VL) for tracheal intubation of neonates results in a higher first-attempt success rate and fewer adverse tracheal intubation-associated events (TIAEs) when compared with direct laryngoscopy (DL). DESIGN: Single-centre, parallel group, randomised controlled trial. SETTING: University Medical Centre Mainz, Germany. PATIENTS: Neonates <440/7 weeks postmenstrual age in whom tracheal intubation was indicated either in the delivery room or in the neonatal intensive care unit. INTERVENTION: Intubation encounters were randomly assigned to either VL or DL at first attempt. PRIMARY OUTCOME: First-attempt success rate during tracheal intubation. RESULTS: Of 121 intubation encounters assessed for eligibility, 32 (26.4%) were either not randomised (acute emergencies (n=9), clinicians' preference for either VL (n=8) or DL (n=2)) or excluded from the analysis (declined parental consent (n=13)). Eighty-nine intubation encounters (41 in the VL and 48 in the DL group) in 63 patients were analysed. First-attempt success rate was 48.8% (20/41) in the VL group compared with 43.8% (21/48) in the DL group (OR 1.22, 95% CI 0.51 to 2.88).The frequency of adverse TIAEs was 43.9% (18/41) and 47.9% (23/48) in the VL and DL group, respectively (OR 0.85, 95% CI 0.37 to 1.97). Oesophageal intubation with concomitant desaturation never occurred in the VL group but in 18.8% (9/48) of intubation encounters in the DL group. CONCLUSION: This study provides effect sizes for first-attempt success rates and frequency of TIAEs with VL compared with DL in the neonatal emergency setting. This study was underpowered to detect small but clinically important differences between the two techniques. The results of this study may be useful in planning future trials.

Background: Intubation of neonates is difficult and hazardous. Factors associated with procedure-related adverse events and unsuccessful intubation attempts are insufficiently evaluated, especially during neonatal nasotracheal intubations. Objective: Aim of this study was to determine the frequency of tracheal intubation-associated events (TIAEs) during neonatal nasotracheal intubations and to identify factors associated with TIAEs and unsuccessful intubation attempts in our neonatal unit. Methods: This was a prospective, single-site, observational study from May 2017 to November 2019, performed at a tertiary care neonatal intensive care unit in a German academic teaching hospital. All endotracheal intubation encounters performed by the neonatal team were recorded. Results: Two hundred and fifty-eight consecutive intubation encounters in 197 patients were analyzed. One hundred and forty-eight (57.4%) intubation encounters were associated with at least one TIAE. Intubation inexperience (<10 intubation encounters) (OR = 2.15; 95% CI, 1.257-3.685) and equipment problems (OR = 3.43; 95% CI, 1.12-10.52) were predictive of TIAEs. Intubation at first attempt (OR = 0.10; 95% CI, 0.06-0.19) and videolaryngoscopy (OR = 0.47; 96% CI, 0.25-0.860) were predictive of intubation encounters without TIAEs. The first intubation attempt was commonly done by pediatric residents (67.8%). A median of two attempts were performed until successful intubation. Restricted laryngoscopic view (OR = 3.07; 95% CI, 2.08-4.53; Cormack-Lehane grade 2 vs. grade 1), intubation by pediatric residents when compared to neonatologists (OR = 1.74; 95% CI, 1.265-2.41) and support by less experienced neonatal nurses (OR = 1.60; 95% CI, 1.04-2.46) were associated with unsuccessful intubation attempts. Conclusions: In our unit, TIAEs and unsuccessful intubation attempts occurred frequently during neonatal nasotracheal intubations. To improve success rates, quality improvement und further research should target interprofessional education and training, equipment problems and videolaryngoscopy.
RESUMO
BACKGROUND: Nonimmune hydrops fetalis (NIHF) is still a challenging diagnosis. The differential diagnosis is extensive and the success of identifying a cause depends on the thoroughness of efforts to establish a diagnosis. For the early diagnosis of NIHF, a virtual gene panel diagnostic tool was developed. The female premature baby in question was delivered via emergency cesarean at 30 + 1 weeks of gestational age (GA) due to rapidly developing NIHF to a healthy mother. The family history was noncontributory. METHODS: DNA of the family was extracted and sequenced by the virtual hydrops panel with whole-exome sequencing. RESULTS: The hydrops panel revealed Noonan syndrome (NS) with a germline mutation in PTPN11 c.218C>T (p.Thr73Ile). CONCLUSION: The diagnosis of our patient was rapidly confirmed by the hydrops panel. The variant of c.218C>T (p.Thr73Ile) has not yet been described in literature relating to NIHF. Only a few case reports of this variant are known. This particular mutation is associated with Noonan syndrome, congenital heart defect and persistent thrombocytopenia. Few reveal juvenile myelomonocytic leukemia.
