Review of Routes to Administer Medication During Prolonged Neonatal Resuscitation
Bibliographic record
Abstract
OBJECTIVE: During neonatal cardiopulmonary resuscitation, early establishment of vascular access is crucial. We aimed to review current evidence regarding different routes for the administration of medications during neonatal resuscitation. DATA SOURCES: We reviewed PubMed, EMBASE, and Google Scholar using MeSH terms "catheterization," "umbilical cord," "delivery room," "catecholamine," "resuscitation," "simulation," "newborn," "infant," "intraosseous," "umbilical vein catheter," "access," "intubation," and "endotracheal." STUDY SELECTION: Articles in all languages were included. Initially, we aimed to identify only neonatal studies and limited the search to randomized controlled trials. DATA EXTRACTION: Due to a lack of available studies, studies in children and adults, as well as animal studies and also nonrandomized studies were included. DATA SYNTHESIS: No randomized controlled trials comparing intraosseous access versus peripheral intravascular access versus umbilical venous catheter versus endotracheal tube versus laryngeal mask airway or any combination of these during neonatal resuscitation in the delivery room were identified. Endotracheal tube: endotracheal tube epinephrine administration should be limited to situations were no vascular access can be established. Laryngeal mask airway: animal studies suggest that a higher dose of epinephrine for endotracheal tube and laryngeal mask airway is required compared with IV administration, potentially increasing side effects. Umbilical venous catheter: European resuscitation guidelines propose the placement of a centrally positioned umbilical venous catheter during neonatal cardiopulmonary resuscitation; intraosseous access: case series reported successful and quick intraosseous access placement in newborn infants. Peripheral intravascular access: median time for peripheral intravascular access insertion was 4-5 minutes in previous studies. CONCLUSIONS: Based on animal studies, endotracheal tube administration of medications requires a higher dose than that by peripheral intravascular access or umbilical venous catheter. Epinephrine via laryngeal mask airway is feasible as a noninvasive alternative approach for drug delivery. Intraosseous access should be considered in situations with difficulty in establishing other access. Randomized controlled clinical trials in neonates are required to compare all access possibilities described above.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
