I. Core Importance of Neonatal Endotracheal Intubation Training
Endotracheal intubation is a critical procedure in neonatal general anesthesia and emergency resuscitation. The necessity of training stems from neonates' unique anatomical features and high clinical risks: neonates have relatively large tongues that easily obstruct the airway, a higher laryngeal position, short and thick epiglottis, a special angle between the glottis and laryngeal inlet, and the narrowest segment located at the cricoid cartilage level below the glottis—all of which make visualizing the glottis difficult during traditional intubation. Additionally, neonates’ immature organs result in poor tolerance to hypoxia and cardiovascular stimulation. Prolonged intubation time, repeated attempts, or accidental intubation may lead to severe complications such as hypoxic-ischemic encephalopathy, laryngeal edema, and even cardiac arrest.
Traditional direct laryngoscopes have limited visibility and are prone to causing difficult airways. In contrast, video laryngoscopes have become the preferred tool for neonatal intubation due to their expanded field of view and clear glottis visualization. However, systematic training is required to master operational skills, thereby improving intubation success rates, shortening procedure time, and reducing clinical risks.
II. Standard Operation of the SCMEHE Neonatal Endotracheal Intubation Model
Preoperative Lubrication Preparation
Evenly spray an appropriate amount of special lubricant on the mucosal surfaces of the model’s mouth and nose to simulate the human airway environment. Thoroughly apply the special lubricant to the distal 2-3 cm of the endotracheal tube and the mucosal-contacting parts of the laryngoscope blade to reduce frictional resistance, avoid model damage, and prevent operational interference.
Positioning and Visual Field Exposure
Place the model’s head in the "sniffing position" (elevate the occiput to slightly hyperextend the head and lift the mandible) to open the airway. Hold the laryngoscope and insert it from the right side of the model’s mouth, pushing the tongue to the left, and advance to the base of the epiglottis. For direct laryngoscopes, gently lift to expose the glottis; for video laryngoscopes, confirm the glottis position via the screen, clearly distinguish between the esophageal and glottic inlets, and avoid blind intubation.
Tube Insertion and Confirmation
Slowly insert the endotracheal tube along the laryngoscope groove. After the tube’s distal end passes through the glottis, advance it an additional 1-2 cm to prevent shallow or excessive insertion. After removing the laryngoscope, confirm correct tube placement by bag-mask ventilation or auscultating simulated lung sounds.
III. Key Precautions
During training, focus on simulating the anatomical difficulties of the neonatal airway and repeatedly practice laryngoscope insertion angles and glottis identification skills. Operate gently and slowly to develop clinical habits of protecting airway mucosa. Clean the model promptly after training and inspect the integrity of instruments to ensure training accuracy. Standardized training with the SCMEHE model can effectively improve operational proficiency and provide reliable skill support for clinical neonatal intubation.
