Management of neonatal difficult airway emergencies in the delivery room

Immediate postdelivery airway management of neonates with prenatally diagnosed micrognathia: A retrospective observational study

INTRODUCTION

Micrognathic neonates are at risk for upper airway obstruction, and many require intubation in the delivery room. Ex-utero intrapartum treatment is one technique for managing airway obstruction but poses substantial maternal risks. Procedure requiring a second team in the operating room is an alternative approach to secure the obstructed airway while minimizing maternal risk. The aim of this study was to describe the patient characteristics, airway management, and outcomes for micrognathic neonates and their mothers undergoing a procedure requiring a second team in the operating room at a single quaternary care children's hospital.

METHODS

This was a retrospective descriptive study. Subjects had prenatally diagnosed micrognathia and underwent procedure requiring a second team in the operating room between 2009 and 2021. Collected data included infant characteristics, delivery room airway management, critical events, and medications. Follow-up data included genetic testing and subsequent procedures within 90 days. Maternal data included type of anesthetic, blood loss, and incidence of transfusion.

RESULTS

Fourteen deliveries were performed via procedure requiring a second team in the operating room during the study period. 85.7% were male, and 50% had a genetic syndrome. Spontaneous respiratory efforts were observed in 93%. Twelve patients (85.7%) required an endotracheal tube or tracheostomy. Management approaches varied. Medications were primarily a combination of atropine, ketamine, and dexmedetomidine. Oxygen desaturation was common, and three patients experienced bradycardia. There were no periprocedural deaths. Follow-up at 90 days revealed that 78% of patients underwent at least one additional procedure, and one patient died due to an unrelated cause. All mothers underwent cesarean deliveries under neuraxial anesthesia. Median blood loss was 700 mL [IQR 700 mL, 800 mL]. Only one mother required a blood transfusion for pre-procedural placental abruption.

DISCUSSION

Procedure requiring a second team in the operating room is a safe and effective approach to manage airway obstruction in micrognathic neonates while minimizing maternal morbidity.

CONCLUSIONS

Though shown to be safe and effective, more data are needed to support the use of procedure requiring a second team in the operating room as an alternative to ex-utero intrapartum treatment for micrognathia outside of highly specialized maternal-fetal centers.

The application of rapid response team in category 1 emergency caesarean section teaching for OBGYN residents in the delivery room

Category 1 cesarean section (CS) can be a life-saving procedure when there is immediate threat to the life of the woman or fetus. However, category 1 CS is a challenge for obstetrics and gynecology residents, and it is necessary to establish an effective and straightforward teaching strategy. This study aimed to evaluate the efficiency of rapid response team (RRT) on category 1 CS teaching for obstetrics and gynecology residents in the delivery room. A total of 142 residents who underwent standardized residency training programs in the delivery room were divided into a RRT teaching group and a traditional response (TR) teaching group. In the RRT teaching group, Category 1 emergency CS teaching was started and explored by rapid response team. The training included both theoretical and practical components. After the training, decision-to-delivery interval (DDI), neonatal Apgar score, operation time and rate of postpartum hemorrhage were compared. A questionnaire on the subjective assessment of various aspects of the program was conducted at the end of the training period. The DDI in minutes in the RRT teaching group (n = 72) was significantly shorter than that of the TR teaching group (n = 70) (11.83 ± 4.16 vs 13.56 ± 5.47, P = .0364). The score of satisfaction from residents in the RRT teaching group was significantly higher than that of the TR group [7 (6, 9) vs 9 (7, 10), P = .0154]. Compared with the TR teaching group, more residents thought their clinical skills have been improved (94.29% vs 100%, P = .0396) and willing to recommend their training method to others (91.43% vs 100%, P = .0399) in the RRT teaching group. However, no significant differences were observed in the incidence of postpartum hemorrhage between the 2 groups. RRT teaching is beneficial in the standardized training and teaching of residents in the delivery room. It improves the DDI of category 1 emergency cesarean section and the degree of satisfaction.

Special consideration in neonatal resuscitation

Delivery room resuscitation of neonates is performed according to evidence-based neonatal resuscitation guidelines. Neonatal resuscitation guidelines focus on the resuscitation of newborns suffering from perinatal asphyxia. Special considerations are needed when resuscitating newborns in locations other than the delivery room and for newborns with congenital anomalies. In this review, we examine the resuscitation of newborns at home and in the emergency department and highlight special considerations for resuscitating newborns with specific congenital anomalies. In addition, we explore the resuscitation of neonates in the neonatal intensive care unit and discuss the potential use of pediatric advanced life support guidelines. Finally, we highlight the importance of simulation to prepare teams for neonatal resuscitations. This review aims to prepare healthcare professionals in all disciplines caring for neonates at risk for requiring resuscitation under special circumstances.

Digital tracheal intubation and finger palpation to confirm endotracheal tube tip position in neonates: A systematic review and meta-analysis

BACKGROUND

To evaluate digital tracheal intubation (DTI) when compared to laryngoscope-assisted TI; finger palpation of endotracheal tube (ETT) tip position when compared to any standard method.

DESIGN

A systematic review of Medline, Embase, CENTRAL, and CINAHL with synthesis of data using meta-analysis was performed.

MAIN OUTCOME MEASURE

The proportion of successful TI and correct ETT tip positioning were the main outcome measures.

RESULTS

Five studies (one observational study and four RCTs) enrolling 310 neonates were included. 94% (81%-98%) of the DTI were successful on the first attempt (certainty of evidence [CoE]: low). The proportion of successful intubation on the first attempt was higher with DTI when compared to laryngoscope-assisted TI (RR 95% CI: 1.81 [1.18; 2.76]) (CoE: very low). Time to successful TI with DTI was 7.4 (95% CI: 6.3, 8.5) s (CoE: low). Time to successful TI was significantly shorter with DTI when compared to laryngoscope assisted TI (MD [95% CI]: -4.9 [-7.3, -2.4] s) (CoE: very low). There was a trend towards a higher proportion of correct ETT tip positions with finger palpation when compared to weight-based formulae alone (RR 95% CI: 1.12 [0.96; 1.31]) (CoE: very low).

CONCLUSIONS

DTI and finger palpation to ascertain ETT tip position in neonates are promising strategies. Future studies with emphasis on their learning trajectory and generalizability are needed.
