Although positive-pressure ventilation (PPV) has traditionally been performed using a face mask in neonatal resuscitation, face mask ventilation for delivering PPV has a high failure rate due to mask leaks, airway obstruction, or gastric inflation. Furthermore, face mask ventilation is compromised during chest compressions. Endotracheal intubation in neonates requires a high skill level, with a first-attempt success rate of <50%. Laryngeal masks can transfer positive pressure more effectively even during chest compressions, resulting in a lower PPV failure rate compared to that of face masks in neonatal resuscitation. In addition, inserting a laryngeal mask is easier and more accessible than endotracheal intubation, and mortality rates do not differ between the 2 methods. Therefore, in neonatal resuscitation, laryngeal masks are recommended in infants with gestational age >34 weeks and/or with a birth weight >2 kg, in cases of unsuccessful face mask ventilation (as a primary airway device) or endotracheal intubation (as a secondary airway device, alternative airway). In other words, laryngeal masks are recommended when endotracheal intubation fails as well as when PPV cannot be achieved. Although laryngeal masks are commonly used in anesthetized pediatric patients, they are infrequently used in neonatal resuscitation due to limited experience, a preference for endotracheal tubes, or a lack of awareness among the healthcare providers. Thus, healthcare providers must be aware of the usefulness of laryngeal masks in depressed neonates requiring PPV or endotracheal intubation, which can promptly resuscitate these infants and improve their outcomes, resulting in decreased morbidity and mortality rates.
尽管在新生儿复苏中传统上一直使用面罩进行正压通气(PPV),但由于面罩漏气、气道阻塞或胃胀气,通过面罩进行PPV通气的失败率很高。此外,在胸外按压期间面罩通气会受到影响。新生儿气管插管需要较高的技术水平,首次尝试成功率<50%。喉罩即使在胸外按压期间也能更有效地传递正压,与面罩相比,在新生儿复苏中PPV失败率更低。此外,插入喉罩比气管插管更容易且更可行,两种方法的死亡率没有差异。因此,在新生儿复苏中,对于胎龄>34周和/或出生体重>2 kg的婴儿,在面罩通气失败(作为主要气道装置)或气管插管失败(作为次要气道装置、替代气道)的情况下,推荐使用喉罩。换句话说,当气管插管失败以及无法实现PPV时,推荐使用喉罩。尽管喉罩常用于麻醉的儿科患者,但由于经验有限、对面气管插管的偏好或医护人员缺乏认识,它们在新生儿复苏中很少使用。因此,医护人员必须意识到喉罩在需要PPV或气管插管的窒息新生儿中的作用,这可以迅速复苏这些婴儿并改善其预后,从而降低发病率和死亡率。
