Objectives: This retrospective cohort study uses endoscopic assessment of the pharyngeal phase of swallowing in infants with laryngomalacia, to ascertain the impact of infant positioning on airway compromise and fluid dynamics during breastfeeding. The study aims to identify whether modification of infant positioning at the breast may improve the possibility of safe, successful breastfeeding in infants with laryngomalacia and concurrent breastfeeding difficulty. Methods: Twenty-three infants referred for noisy breathing and difficulty feeding were assessed with flexible endoscopic evaluation of swallowing (FEES) during breastfeeding. All had endoscopically confirmed laryngomalacia. During FEES, observations were made of clinical signs of airway compromise as well as endoscopically observable anatomical features and swallowing dynamics during breastfeeding, including tongue base position, view of laryngeal inlet and vocal folds, dynamic supraglottic soft tissue collapse, timing of milk flow into pyriform fossae/hypopharynx relative to sucking, and presence of penetration and/or aspiration. If airway and/or swallowing compromise was present, the infant’s initial position at the breast was altered from supine or semi lateral decubitus position to semi-prone, with a description of the clinical and endoscopically observable changes that subsequently occurred. Results: Signs of dynamic airway obstruction and/or compromised airway protection with swallowing were present in 20 of the 23 infants (87%) in their initial supine or semi lateral decubitus position. These 20 infants were repositioned to semi-prone, with improvement and/or resolution of stridor and an improved ability to maintain latch in all infants. Continued endoscopic evaluation following positional change was possible in 16 infants, identifying anterior positioning of the tongue base, reduced dynamic supraglottic tissue collapse, reduced volume of milk flow into pyriform fossae during pauses in sucking and resolution of penetration and aspiration. Conclusion: This study has shown how alteration of breastfeeding position to semi-prone may improve dynamic airway obstruction and reduce aspiration risk in infants with laryngomalacia.
ObjectiveKnowledge of the breastfeeding swallow is limited by practical challenges. Radiation exposure to both mother and infant and the radiolucent properties of breastmilk make videofluoroscopy an unsuitable imaging modality. Furthermore, ultrasound is not ideal for capturing the complex 3‐dimensional functional anatomy of swallowing. In this study we explore the feasibility of using real‐time MRI to capture the breastfeeding swallow.MethodsProspective observational study: Review of imaging from 12 normal infants (<5 months of age) and their mothers while breastfeeding using real‐time MRI.ResultsStatic images were successfully captured in 11 infants and dynamic images in nine infants. This imaging modality confirms the dorsal surface of the infant's tongue elevates the maternal nipple to the hard palate, closing the space around the nipple with no air visible in the oral cavity during sucking and swallowing. We obtained dynamic imaging of mandibular movement with sucking, palatal elevation and pharyngeal constriction with swallowing, diaphragm movement with breathing and milk entering the stomach. Breastmilk was easily visualized, being high intensity on T2 sequences. Technical challenges were encountered secondary to infant movement and difficulties acquiring and maintaining midsagittal orientation. The similarity in tissue densities of the lips, tongue, nipple and hard palate limited definition between these structures.ConclusionReal‐time MRI imaging was successful in capturing dynamic images of the breastfeeding swallow. However, technical and practical challenges make real‐time MRI unlikely at present to be suitable for swallow assessment in clinical practice. Advances in technology and expertise in dynamic image capture may improve the feasibility of using MRI to understand and assess the breastfeeding swallow in the near future.Level of evidence4.
BackgroundTracheostomy management is considered an area of advanced practice for speech–language therapists (SLTs) internationally. Infrequent exposure and limited access to specialist SLTs are barriers to competency development.AimsTo evaluate the benefits of postgraduate tracheostomy education programme for SLTs working with children and adults.Methods & ProceduresA total of 35 SLTs participated in the programme, which included a 1‐day tracheostomy simulation‐based workshop. Before the workshop, SLTs took an online knowledge quiz and then completed a theory package. The workshop consisted of part‐task skill learning and simulated scenarios. Scenarios were video recorded for delayed independent appraisal of participant performance. Manual skills were judged as (1) completed successfully, (2) completed inadequately/needed assistance or (3) lost opportunity. Core non‐medical skills required when managing a crisis situation and overall performance were scored using an adapted Ottawa Global Rating Scale (GRS). Feedback from participants was collected and self‐perceived confidence rated prior, immediately post and 4 months post‐workshop.Outcomes & ResultsSLTs successfully performed 94% of manual tasks. Most SLTs (29 of 35) scored > 5 of 7 on all elements of the adapted Ottawa GRS. Workshop feedback was positive with significant increases in confidence ratings post‐workshop and maintained at 4 months.Conclusions & ImplicationsPostgraduate tracheostomy education, using a flipped‐classroom approach and low‐ and high‐fidelity simulation, is an effective way to increase knowledge, confidence and manual skill performance in SLTs across patient populations. Simulation is a well‐received method of learning.
