[Endotracheal intubation of patients with Pierre-Robin sequence. Successful use of video intubation laryngoscope]

[The Pierre Robin sequence from an anesthesiologic perspective : Presentation of the procedure based on a retrospective analysis at a university hospital]

INTRODUCTION

As part of surgical interventions in pediatric patients, children with craniofacial malformations and syndromes are presented in the field of oral and maxillofacial surgery, anesthesia and also in all other clinical disciplines. In particular, the Pierre Robin sequence in the clinical context leads to a situation albeit a rare one, which should be given high attention in preoperative, intraoperative and postoperative care.

MATERIAL AND METHODS

In a retrospective analysis from 1993 to 2020 in the Department of Oral and Maxillofacial Surgery at the University Hospital Halle (Saale), a total of 54 patients were identified with syndromic changes and a need for surgical treatment. During this period, 12 patients with a Pierre Robin sequence were genetically confirmed, who received a total of 20 surgical interventions under general anesthesia at different times. Statistical analysis was performed using SPSS 17.0.

RESULTS

In 12 patients with a Pierre Robin sequence, 20 surgical procedures were performed with the patient under general anesthesia. The youngest patients had an average age of 6 months, the oldest 16 years at the time of the operation. The average age was 5.7 years. In addition to the genetic component, all children were assigned to the ASA I classification. The surgical indication was initially an isolated cleft palate in all patients, followed by further interventions such as dental restorations, corrective surgery in the area of the palate or ear nose throat (ENT) examinations. Drug induction of general anesthesia was weight-adapted using propofol 1%, fentanyl or remifentanil and rocuronium. In our study, out of 18 orotracheal intubations, only 2 patients had to be intubated by video laryngoscopy. One patient required nasal intubation and another was fitted with a laryngeal mask. The success rate of conventional intubation was 89.5%. Postoperatively, one infant had recurrent drops in saturation, so that reintubation was necessary.

Adoption of video laryngoscopy in Massachusetts emergency departments

BACKGROUND

Previous research suggests that video laryngoscopy may be superior to direct laryngoscopy.

OBJECTIVES

We sought to determine the proportion of Massachusetts emergency departments (EDs) that have adopted video laryngoscopy, the characteristics of user and non-user EDs, the reasons why non-users do not use video laryngoscopy, and how the adoption of video laryngoscopy compares to typical technology adoption life cycles.

METHODS

Surveys were mailed to directors of all non-federal EDs in Massachusetts (n=74) in early 2009. Non-responders received repeat mailings and were then contacted via telephone or e-mail.

RESULTS

Sixty-three of 74 (85%) EDs responded and 43% had adopted video laryngoscopy. EDs with video laryngoscopy had a higher median annual visit volume than EDs without video laryngoscopy (48,000 vs. 36,500, p=0.04), but had similar mean intubations per week (4.5 vs. 4.4, p=0.97) and mean surgical airways per year (0.7 vs. 1.1, p=0.19). Half of the EDs affiliated with emergency medicine residency programs had video laryngoscopy available. Among EDs with video laryngoscopy, the technology had been available for>5 years in 4% (1/27), 1-5 years in 44% (12/27), and<1 year in 52% (14/27). Although EDs not using video laryngoscopy did not do so primarily because it was too expensive (69% [25/36]), video laryngoscopy adoption has still progressed more rapidly than predicted by the typical technology adoption timeline.

CONCLUSION

Video laryngoscopy has been adopted by 43% of Massachusetts EDs; results were similar in academic institutions. Cost is the primary barrier to adoption for non-user EDs, but adoption is progressing more rapidly than expected for a new technology.

Fibreoptic and videoscopic indirect intubation techniques for intubation in children

Endotracheal intubation in the pediatric emergency department can be challenging. Direct laryngoscopy is the primary intubation technique used in pediatric emergency intubations. However, cases arise where abnormalities of the upper airway prevent a direct view of the laryngeal opening. Under these circumstances, indirect means of visualization of the laryngeal opening using fiberoptic and videoscopic devices can be used to successfully achieve intubation. A wide range of instruments including flexible, rigid, and semirigid devices are available. Those who practice emergency medicine should be aware of these devices and be skilled in their use and aware of their limitations.

Management of the paediatric airway: new developments

During the last 2 years, some interesting new devices have been made available to improve airway management in children and infants, and several studies have advanced our understanding concerning risks and benefits of the current practice in the field. Certain risk factors for airway related problems during anaesthesia in children having a cold have been identified, and new aspects of the controversy concerning the use of cuffed endotracheal tubes in children presented. Novel video-assisted systems have been introduced for the management of the difficult airway in paediatric patients, and new applications for well known devices have been suggested, such as the laryngeal mask airway serving as guidance for fibreoptic intubation. Recent studies also demonstrated specific problems with the laryngeal mask airway in infants, as well as the advantages of a new prototypic laryngeal mask airway for children, similar to the ProSeal (LMA International S.A. Group, USA). Furthermore, the following review presents new data about the use of the cuffed oropharyngeal airway, the laryngeal tube, and the Arndt bronchus blocker in paediatric patients.
