Background: Complete upper airway obstruction by a foreign body is a dramatic and acute emergency situation, and can result in rapid development of hypoxia, circulatory arrest and death. Special Magill pliers with an adjustable video optical system have been developed for airway inspection to facilitate efforts to remove foreign bodies causing obstruction of the upper airway.Objective: To remove a simulated airway foreign body from a cardiopulmonary resuscitation (CPR) manikin, either with normal Magill pliers or with the newly designed video Magill pliers.Material and Methods: After a brief introduction, 81 kindergarten teachers, 51 pupils (age 10-14 years) and 52 prospective emergency physicians were asked to remove a 2 × 2 "Lego" brick from the hypopharynx of a CPR manikin using either standard Magill pliers or the newly designed video Magill pliers. The formal hypothesis was that there would be no differences between the methods. Successful removal was defined as when the first removal attempt resulted in the Lego brick passing beyond the teeth of the manikin within 60s.Results: The use of the video Magill pliers resulted in significantly higher success rates in removal of the simulated foreign airway body within 60 s compared to standard Magill pliers in kindergarten teachers (84% vs. 30%, p < 0.0001), pupils (84% vs. 18%, p < 0.0001) and prospective emergency physicians (92% vs. 40%, p < 0.0001). The time needed for removing the foreign airway body was significantly shorter in groups using the video Magill pliers (kindergarten teachers 29 ± 18s vs. 45 ± 19 s, pupils 29 ± 18s vs. 54 ± 14 s, and prospective emergency physicians 33 ± 18s vs. 45 ± 20 s; p < 0.0001). In an analogue points system (from 1 very simple to 10 extremely complicated), the user friendliness of the video Magill pliers was judged to be significantly higher than the standard Magill pliers (2.8 ± 1.6 vs. 7.8 ± 2.7 kindergarten teachers, 2.0 ± 1.3 vs. 7.2 ± 2.5 pupils and 3.2 ± 2.2 vs. 4.9 ± 3.1 prospective emergency physicians, p < 0.0001). Visibility of the airway foreign body was estimated to be significantly better employing the video Magill pliers compared to the standard Magill pliers (1.9 ± 1.4 vs. 9.8 ± 0.6 kindergarten teachers, pupils 1.3 ± 0.6 vs. 9.2 ± 1.6, prospective emergency physicians 2.3 ± 1.8 vs. 9.1 ± 2.3, p < 0.0001).Conclusion: In this study kindergarten teachers, pupils (aged 10-14 years) and prospective emergency physicians had higher success rates in less time and reported better user friendliness and visibility using video Magill pliers compared to standard Magill pliers for removing a simulated foreign body from a CPR manikin airway.

A 21-year-old female was injured by accidental strangulation. Dyspnea and stridor occurred with delay, and led to emergency intubation.Physical examination showed strangulation marks and neck emphysema. Computed tomography confirmed laryngotracheal separation and revealed misplacement of the ventilation tube.Further surgical exploration revealed complete laryngotracheal (cricotracheal) separation.After initial emergency tracheotomy, cricotracheal reanastomosis was achieved by a two-stage surgical approach.Laryngotracheal separation is associated with high mortality. In the case presented herein, the patient survived and was discharged from hospital without a tracheostomy tube despite bilateral recurrent laryngeal nerve palsy.ANAMNESE: Eine 21-jährige Patientin erlitt im Rahmen eines Unfalls ein schweres Strangulationstrauma. Stridor und Dyspnoe setzten erst mit Verzögerung ein und führten zur Notfallintubation.Im Rahmen der klinischen Untersuchung zeigten sich Strangulationsmarken und ein Emphysem der Halsweichteile. Die Computertomographie erhärtete den Verdacht auf einen Abriss der Trachea vom Kehlkopf und ergab eine Fehllage des Beatmungstubus.Bei der weiteren chirurgischen Exploration zeigte sich eine komplette laryngotracheale (krikotracheale) Separation.Nach initialer Nottracheotomie wurden in einem zweizeitigen operativen Verfahren die krikotracheale Reanastomosierung und die Retracheostomie durchgeführt.Laryngotracheale Separationen stellen den höchsten Schweregrad der Kehlkopfverletzungen dar und sind mit einer hohen Mortalität behaftet. Im geschilderten Fall überlebte die Patientin und konnte, trotz beidseitiger Rekurrensparese, dekanüliert entlassen werden.

Die Mukoziliäre Clearance (MC) stellt den primären Abwehrmechanismus in den Atemwegen dar, welcher für den Abtransport von eingeatmeten Mikroorgansimen, Allergenen und Partikeln verantwortlich ist. Die MC wird durch den koordinierten Schlag der zilientragenden Zellen sowie durch die Produktion von Mucus gewährleistet. Störungen in der MC führen zu verschiedenen Krankheitsbildern, wie der cystischen Fibrose, und zeigen die Relevanz dieses Abwehrmechnismus auf. Die MC wird in erster Linie akut über die Schlaggeschwindigkeit der Zilien reguliert, bekannte Aktivatoren stellen verschiedene Signalmoleküle, wie NO, ATP oder Acetylcholin (ACh) dar. In den oberen Atemwegen sowie in der Trachea und den Hauptbronchien der Maus sind sogenannte solitäre chemosensorische Zellen (SCC) lokalisiert. Dieser Zelltyp exprimiert das ACh synthetisierende Enzym ChAT und wird daher auch als solitäre cholinerge chemosensorische Zelle (SCCC) bezeichnet. Zudem exprimieren SCC Komponenten der Geschmackstransduktionskaskade, wie TRPM5 und PLCβ2. Durch die Freisetzung von ACh könnten SCCC die MC direkt beeinflussen. SCC sind an verschiedenen Stellen des Körpers, an denen dieser gegenüber der Umwelt exponiert ist, lokalisiert, z.B. der Konjunktiva, dem Magen-Darm-Trakt und der Urethra. Dieser Zelltyp scheint im Allgemeinen eine Wächterfunktion einzunehmen. Je nach Organ bestehen Unterschiede in den Stimuli, die SCCC aktivieren können, z.B. im Darm Endoparasiten, in der Nase bakterielle Produkte oder Allergene, und den durch die SCCC freigesetzten Effektormolekülen, wie Leukotriene, IL-25 oder ACh. Die ACh-Freisetzung aus SCCC wurde bis dato nur indirekt über Versuche mit Inhibitoren für nAChR nachgewiesen. Ziel dieser Arbeit war es zum einen, die trachealen SCCC, im Besonderen deren postnatale Entwicklung, genauer zu untersuchen, zum anderen, neue Agonisten für SCCC zu identifizieren und zu untersuchen, ob diese oder bereits bekannte Aktivatoren zu einer Freisetzung von ACh aus SCCC führen, sowie ob diese die MC beeinflussen. In einem weiteren Abschnitt sollte untersucht werden, ob SCCC in den Atemwegen eine Wächterfunktion einnehmen und ob das Fehlen oder die Unterbrechung der Geschmackstransduktionskaskade innerhalb der SCCC zu einer erhöhten Anfälligkeit der Tiere gegenüber einer bakteriellen Atemwegsinfektion führt. Hierzu wurden verschiedene Mausstämme verwendet, in denen SCCC markiert, SCCC ablatiert oder einzelne Proteine deletiert wurden. Murine Tracheen wurden explantiert, der Zilienschlag (CBF) sowie die MC (PTS) gemessen und der ACh-Gehalt im Überstand bestimmt. Zudem wurde ein optogenetisches Modell verwendet, um die ACh-Freisetzung aus SCCC zu untersuchen. In finalen Experimenten wurden die Anfälligkeit für bakterielle Infekte in zwei Mausstämmen mit zwei verschiedenen Infektionsmodellen untersucht (B. pseudohinzii und S. pneumoniae). Es zeigte sich, dass tracheale SCCC bereits kurz vor der Geburt (E18) in geringer Zahl vorhanden sind und sich die Anzahl postnatal rapide erhöht. In adulten Tieren konnte eine verringerte SCCC-Anzahl in Tlr2/4- sowie Myd88-defizienten Tieren beobachtet werden, dies spricht für die Interaktion zwischen der bakteriellen Besiedlung der Versuchstiere und der Anzahl der SCCC. Mit Hilfe von PTS-Versuchen konnte mit formylierten Peptiden eine neue Klasse von bakteriellen Produkten identifiziert werden, welche die MC steigern, wobei festzuhalten ist, dass ein bestimmtes Kernmotiv (f-MKKFR) an Aminosäuren notwendig ist, um die MC zu erhöhen. So führte das Peptid f-MKKFRW zu einem Anstieg der CBF um ~70 % und der PTS um ~83 %. Diese Peptide werden hoch konserviert von typischen Atemwegserregern, wie S. pneumoniae und K. pneumoniae, produziert und konnten zudem in Patientenproben nachgewiesen werden. In weiteren Versuchen wurde gezeigt, dass SCCC und Komponenten der Geschmackstransduktionskaskade essentiell für die Wahrnehmung dieser Peptide sind und diese zu einer ACh-Freisetzung aus SCCC führen. Dieses erhöht direkt den Zilienschlag über den muskarinischen ACh-Rezeptor 3 auf zilientragenden Zellen. Eine Beteiligung von sensorischen Nervenfasern wurde dagegen ausgeschlossen. Die ACh-Freisetzung aus SCCC wurde mit Hilfe von drei Versuchsansätzen bestätigt. Erstens, führte die Applikation von f-MKKFRW zu einer TRPM5-abhängigen ACh-Freisetzung aus SCCC, welche mittels HPLC bestimmt wurde. Zweitens, führte die zelltypspezifische Ablation der ChAT zu einer Verringerung der PTS-steigernden Wirkung von f-MKKFRW. Drittens, führte die optogenetische Stimulation von SCCC ebenfalls zu einer ACh-Freisetzung. Bekannte Aktivatoren von SCCC, sogenannte Bitterstoffe (Denatonium, Cycloheximid), führten jedoch zu keiner ACh-Freisetzung aus SCCC. Durch eine retrospektive und randomisierte Studie an Tieren, welche mit B. pseudohinzii infiziert waren, konnte nachgewiesen werden, dass Trpm5-defiziente Tiere eine höhere Bakterienlast in der Trachea und eine höhere Infektionsrate der Lunge aufwiesen. Dagegen unterschieden sich Tiere, in denen SCCC ablatiert wurden, nach einer Infektion mit S. pneumoniae in verschiedenen Parametern wie der Ausprägung der Pneumonie, nicht von den Kontrolltieren, es konnte jedoch eine Zunahme der trachealen SCCC beobachtet werden. Aus den gewonnenen Daten lässt sich schlussfolgern, dass tracheale SCCC als Wächterzellen fungieren und bakterielle Produkte, insbesondere formylierte Peptide mit dem Kernmotiv f-MKKFR wahrnehmen können. Erstmals konnte nachgewiesen werden, dass diese Peptide die MC steigern und dass dies durch die Freisetzung von ACh aus SCCC geschieht. Zudem konnte erstmals die direkte ACh-Freisetzung aus SCCC nachgewiesen werden. Das Vorkommen der MC-steigernden Peptide in mehr als 13 typischen Atemwegspathogenen und die Präsenz dieser Peptide in Patientenproben sprechen für eine mögliche klinische Relevanz der neu identifizierten Peptide. Zudem deutet die beobachtete erhöhte Infektanfälligkeit in den Atemwegen von Trpm5-defizienten Tieren auf eine Beteiligung dieses Zelltyps an der Früherkennung und Vermeidung von bakteriellen Atemwegsinfektionen hin.

This is a case report of a 45-year-old patient, 39 weeks of gestation, who was intubated via rapid sequence induction (RSI) for an emergency cesarean. The indication for emergency cesarean was a pathological cardiotocography during the ejection phase following labor induction.Despite the primary use of a video laryngoscope, there was difficulty aligning the laryngeal axis. Therefore, an internal stylet was used to heavily angulate the endotracheal tube (ETT) to a hockey stick shape to enter the larynx.Postoperative dyspnea and extensive facial swelling were initially diagnosed as an allergic reaction. Only 22 h later the diagnosis of tracheal rupture was confirmed following computer tomography.We hypothesized that the mechanism of injury was due to excessive pressure transmitted to the tip of the ETT. This probably occurred due to a leverage effect caused by the withdrawal of the heavily bent stylet from the ETT, forcing an intratracheal cranial movement of the ETT.By conducting an experiment on a pig's trachea, we were able to visualize this mechanism of injury. In addition, we were able to demonstrate that bending the stylet to a similar angle as the laryngoscope blade led to minimal movement of the tip of the ETT.Therefore, when using a stylet during intubation, we recommend bending the ETT and stylet to the shape of the used laryngoscope blade and retracting the stylet at a similar angle to avoid complications, such as tracheal rupture.Eine 45-jährige Patientin erhielt in der 39. Schwangerschaftswoche bei suspektem Kardiotokogramm in der Austreibungsphase nach Geburtseinleitung eine Rapid Sequence Induction (RSI) zur Notsectio.Trotz primärer Verwendung eines Videolaryngoskops war die Einstellung der Stimmbandebene erschwert, sodass der Tubus mithilfe des Führungsstabs stärker anguliert wurde („hockey stick“), womit die Stimmbandebene passiert werden konnte.Eine Dyspnoe mit ausgedehnter Schwellung im Gesicht führte postoperativ initial zur Fehldiagnose einer allergischen Reaktion. Erst 22 h später konnte die Diagnose einer Trachealverletzung mithilfe einer Computertomographie gesichert werden.Die Hypothese zur Entstehung der Verletzung lautet, dass aufgrund der Hebelwirkung durch das Zurückziehen des Führungsstabs aus einem stark angulierten Tubus eine erhebliche Kraft auf die Tubusspitze übertragen wurde. Durch das Zurückziehen des Führungsstabs bewegte sich die Tubusspitze in der Trachea nach kranial, wodurch es vermutlich zum Trachealriss kam.In einem Experiment an einer Schweinetrachea konnten wir dies visualisieren. Zudem wiesen wir nach, dass das Zurückziehen eines Führungsstabs, welcher in Form des Laryngoskopspatels gekrümmt ist, zu fast keiner Bewegung der Tubusspitze führt.Daher empfehlen wir, den Tubus immer in Form des Spatels vorzubiegen und den Führungsstab in einer entsprechenden bogenförmigen Bewegung herauszuziehen, um Komplikationen wie in unserem Fall vorzubeugen.

Case discussion of a 51-year-old female patient with ventilator dependency due to Charcot-Marie-Tooth-Hoffmann syndrome (HMSN I) and cervical spinal fusion with complex tracheal canula management. Following 16 years of noninvasive ventilation due to chronic hypercapnic failure with 24 hour dependency on the ventilator, an elective surgical tracheostomy and switch to invasive ventilation was carried out. Because of severe cervical scoliosis, common tracheal canulae could not provide an adequate fit. With development of a 3D model according to the CT scans of the patient, an individualized tracheal tube was customized that provided excellent ventilatory results and the ability to speak during invasive ventilation.Falldarstellung einer 51-jährigen Patientin mit beatmungspflichtigem Charcot-Marie-Tooth-Hoffmann-Syndrom (HMSN I) sowie Spondylodese der Halswirbelsäule bei Skoliose mit komplexem Trachealkanülenmanagement. Nach anfänglicher nichtinvasiver Beatmung über 16 Jahre erfolgte bei dauerhafter Abhängigkeit von der nichtinvasiven Beatmung über 24 Stunden und progredienter respiratorischer Insuffizienz die elektive plastische Tracheotomie mit invasiver Beatmung. Aufgrund der zervikalen Spondylodese konnte mit herkömmlichen Trachealkanülen keine zufriedenstellende Versorgung erreicht werden und es erfolgte eine individuelle Anpassung einer Trachealkanüle anhand eines 3D-Druckmodells des trachealen Verlaufs mit nachfolgender hervorragender Beatmungsqualität und Sprechmöglichkeit unter invasiver Beatmung.

- Abstract
The technique of ultrasound-guided retrograde intubation is a less invasive procedure for airway management especially in an emergency situation with massive bleeding. This article describes a case of postoperative neck bleeding into the pharynx and neck leading to significant anatomical impairment combined with laryngeal obstruction that was successfully managed using this technique in a modified way. Anatomically non-palpable from a superficial approach, conventional cricotomy and awake tracheotomy were not possible and attempts of fiber optic intubation failed; therefore, ultrasound-guided tracheal puncture was used to advance a conventional central line guidewire towards and out of the mouth and to install orotracheal intubation via a Cook airway catheter cut in half which was advanced over the wire. All airway material remained in place in order to secure the airway until permanent tracheostomy was established along the wire entrance. Sufficient ventilation was possible with the Cook catheter and wire still in the tube. No hypoxic episodes occurred and the patient achieved full recovery. [ABSTRACT FROM AUTHOR]

Local recurrence of thyroid carcinomas can result in tumor infiltration in the lower region of the larynx. Since these tumors typically no longer store iodine, treatment options are greatly limited. The present study describes our experience with laryngo-tracheal resection of such cases of local recurrence. From July 2019 to November 2020, we treated five patients with malignant infiltration of the trachea and larynx due to local recurrence of a thyroid carcinoma. We performed laryngo-tracheal resection with end-to-end anastomosis in four patients and frontolateral partial laryngectomy in one patient. The median length of hospital stay was 6 days (5-14). An R0 resection was performed in two patients. Problems with the anastomosis or bilateral recurrent laryngeal nerve paralysis was not seen in any of the patients. One patient had to be reintubated on the second postoperative day due to lung failure. He was able to be extubated after five days. High tracheal resection with partial resection of the larynx was able to be performed with minimal risk. Although radical resections are rare, they expand oncological treatment options in the case of local recurrence of thyroid carcinomas that are iodine-refractory. High tracheal resection could be part of the oncological treatment spectrum in the case of local recurrence of thyroid carcinomas that no longer store iodine.ZIEL: Lokalrezidive von Schilddrüsenkarzinomen können zu einer Tumorinfiltration im unteren Kehlkopfbereich führen. Da diese Tumoren in der Regel nicht mehr jodspeichernd sind, sind die weiteren Therapieoptionen erheblich eingeschränkt. Die vorliegende Arbeit beschreibt unsere Erfahrung mit laryngotrachealen Resektionen dieser Lokalrezidive. Von Juli 2019 bis November 2020 behandelten wir 5 Patienten mit maligner Infiltration der Trachea und des Larynx durch ein Lokalrezidiv eines Schilddrüsenkarzinoms. Wir führten bei 4 Patienten eine laryngotracheale Resektion mit End-zu-End-Anastomose durch, bei einer Patientin erfolgte eine frontolaterale Teillaryngektomie. Der Krankenhausaufenthalt betrug median 6 Tage (5–14). Eine R0-Resektion wurde nur bei 2 Patienten erreicht. Bei keinem Patienten traten Probleme mit der Anastomose oder eine beidseitige Rekurrensparese auf. Ein Patient musste am ersten postoperativen Tag wegen zunehmenden Lungenversagens reintubiert werden. Er konnte nach 5 Tagen extubiert werden. Hohe Trachealresektionen mit Teilresektion des Larynx können mit geringem Risiko durchgeführt werden. Obwohl onkologisch radikale Resektionen selten sind, stellen diese Resektionen eine Erweiterung der Therapieoptionen bei jodrefraktären Lokalrezidiven von Schilddrüsenkarzinomen dar. Hohe Trachealresektionen könnten Teil des onkologischen Therapiespektrums beim lokal rezidivierenden, nicht mehr Jod speichernden Schilddrüsenkarzinom werden.

- Abstract
Centuries ago an "algorithm" was originally inaugurated to depicture a pathway to solve mathematical problems using a decision tree. Nowadays this tool is also well established in clinical medicine. Ever since management errors in difficult airway handling and subsequent litigations remain high referring to ASA closed claims database. However, even since 2010, the ESA postulates every institution dealing with airway management should have a DAM algorithm (ESA Declaration of Helsinki on Patient Safety in Anaesthesiology). In 2018 a systematic review of 38 international DAM algorithms was published; most of them show a four-step flow chart: failed tracheal intubation, insufficient bag-mask ventilation and supraglottic airway, leads to establish an emergency sugical airway. In conclusion authors state that a universal, globally valid, DAM algorithm is lacking. German language guideline development is governed by the AWMF, which labels guidelines with the highest evidence levels and methodological strength "S3". The ASA published a revised DAM practice guideline in 2022, which was developed by 13 international members and was endorsed by international anesthesiological societies. - Though it is based on a systematic literature search and evaluation, final recommendations (without grading) were generated by a survey among experts in the field: Pre-procedural evaluation of the airway is essential; meanwhile more data are available especially regarding ultrasound examination of the upper airway and in 2022 a promising nomogram was developed for the prediction of difficult laryngoscopy. Pre-procedural planning of expected DAM: it should be decided beforehand, if awake intubation is feasible for the patient. Preoxygenation of every elective patient (3 mins with PEEP 5 cmH
2 O, aim: 95% pulse oxymetry) and continuous nasal high-flow oxygen delivery during airway management. In case of unexpectedly difficult/emergency airway, ASA recommends: call for help, use cognitive aid (algorithm), consider restoration of spontaneous breathing, adjust bag-mask ventilation, monitor time passing; if "cannot intubate, cannot oxygenate" situation occurs (etCO2 < 10 mmHg, < 80% pulse oxymetry) establish surgical airway; if failed consider ECMO therapy, if feasible and available. ASA restricts intubation attempts to 3+ based on experience and decision of the clinician, however evidence shows, that attempts should not exceed 2 attempts to avoid serious complications, e.g. hyoxemia and even cardiopulmonary resuscitation (CPR). Additionally, we recommend a cockpit strategy for airway management using crisis resource elements as used in aviation (situation awareness, sterile communication, read-back/hear-back and canned decisions) and a supervisor/team leader as already established in CPR. Last, but not least, continuous airway management training increases algorithm adherence., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Independent of the type of critical illness, tracheostomized patients have a high risk of developing a dysphagia. This is potentially life-threatening as it can lead to aspiration and pneumonia. It is therefore essential to perform swallowing diagnostics by means of a bolus dyeing test and/or FEES before oral feeding. Since a physiological airflow through the larynx and adequate subglottic pressure are key components of an effective swallowing act, oralisation should be avoided as far as possible with a blocked tracheal cannula., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Advanced thyroid carcinomas with infiltration of the aerodigestive tract are rare but are responsible for approximately 50% of the tumor-specific mortality. Due to impending and frequently life-threatening local complications and in the absence of promising therapeutic alternatives, a resection in curative or palliative intention is indicated if the local tumor is resectable. The resection and especially reconstruction of the trachea represent an extraordinary surgical challenge, require an individualized approach as well as exact knowledge of tracheal resection techniques. The decision for surgery in general, the selection of adequate resection and reconstruction strategies as well as the perioperative management should be accompanied by a particularly experienced interdisciplinary team.

Tracheal injuries are altogether rare events and can be divided into three broad categories: tracheobronchial injuries caused by external violence, iatrogenic ruptures of the trachea and inhalation trauma. Successful management of tracheobronchial injuries requires a fast and straightforward diagnostic evaluation. In all severely injured patients with cervicothoracic involvement an injury of the tracheobronchial system should be actively excluded. Although it is commonly agreed that posttraumatic injuries require surgical intervention the management of iatrogenic injuries is presently shifting towards a more conservative treatment.

Primary tumors of the trachea account for less than 0.1% of all tumors. They are malignant in more than 90% of cases with squamous cell carcinoma and adenoidcystic carcinoma accounting for 2/3 of all tracheal tumors. Since they are often misdiagnosed as asthma or chronic lung disease, diagnosis can be delayed for years. Once the diagnosis has been established, surgical resection being the only curative treatment should be considered first. Modern techniques for tracheal surgery such as laryngotracheal, tracheal or carinal resection and different tracheal mobilisation maneuvers such as laryngeal and hilar release allow for resection of more than 50% of the trachea and anastomosis without excessive tension. Results in patients with complete tumor resection are good with 5-year and 10-year survival between 39% and 79% and between 18% and 51%, respectively. However, careful patient evaluation, preservation of tracheal blood supply and accepting the limits of resectability are mandatory to avoid major complications that accompany tracheal resections in more than 20% of cases depending on the type of resection.

During surgical procedures of the upper respiratory tract anesthesiologists and surgeons are often in a kind of competition situation because of the close spatial relationship between the airway of the patient and the surgical area. Nevertheless endotracheal intubation is still preferred as the gold standard of airway management. Especially in laryngeal surgery the use of high-frequency jet ventilation (HFJV) offers an alternative to the endotracheal tube. During HFJV the ventilation gas is intermittently administered by an injector with a high frequency into the airway which is open to the outside. Exhalation occurs passively in the area nearby the wall of the airway cross-section. According to the availability of the technique and the indications jet ventilation can be implemented in an infraglottic, supraglottic, transtracheal or transluminal manner. To exert influence on gas exchange of the patient the respiratory rate, driving pressure, oxygen concentration and inspiration time can be changed according to the needs. Severe tracheal stenosis, risk of excessive bleeding during the procedure, patients at risk for aspiration and exacerbation of lung diseases are depicted as contraindications for HFJV. Complications under HFJV are rare despite the limited conditions for monitoring gas exchange and mechanics of ventilation in contrast to conventional ventilation. A particular challenge for the anesthesiologist is the use of HFJV during laryngeal laser surgery. Basic elements of the anesthetic management to prevent airway fire is the application of a laser-resistant jet catheter, the maintenance of anesthesia with total intravenous anesthesia and the reduction of the inspiratory oxygen concentration (FO) to less than 0.3.

The safe use of cuffed tracheal tubes for children necessitates a cuff pressure limitation at 20–25 cmH2O. The aim of the study was to evaluate the reliability and benefit of a new cuff pressure release valve (opening pressure 20 cmH2O) for children intubated with a cuffed tracheal tube. In a prospective, observational trial cuff pressure was recorded in paediatric and adolescent patients intubated with a cuffed tracheal tube during sevoflurane/nitrous oxide anaesthesia. The cuff pressure release valve was interposed between the cuff manometer and the pilot balloon. In 25 patients measurements were started at the initial opening pressure (group A) and in a further 25 patients measurements were started at the minimal sealing cuff pressure (group B). A total of 50 patients, aged from 0.4 to 17.8 years (median 7.4 years) were enrolled in the study. The opening pressure measured (group A) was 19.7±0.8 cmH2O and the cuff sealing pressure (group B) was 11.7±2.9 cmH2O (range 6–16 cmH2O). Mean cuff pressure values in group A were 20.4±1.6 cmH2O and 16.5±3.3 cmH2O in group B. In one patient (group A) the cuff pressure exceeded 25 cmH2O and was manually decreased to 20 cmH2O. In total, 24 filling procedures (group A 14; group B 10) were required during 103.1 h of investigation because of cuff pressure drop and audible air leakage, mainly caused by cuff pressure increases and consequent releases during patient positioning. Our data demonstrate that the tested cuff pressure release valve was useful and reliable to limit cuff pressure in tracheal intubated children and adolescents within an acceptable pressure range.

Tracheostomy is one of the oldest procedures in surgery. Although it was traditionally used for treatment of upper airway stenosis, the primary surgical indication is now in the long-term intensive care unit patient. Here, the aims are avoidance of damage to the larynx, earlier weaning from artificial respiration and improved nursing care. Apart from the conventional operating method, minimally invasive procedures have been increasingly employed. More than 20,000 ICU patients per annum are now treated in Germany by these modern methods. Common features of these procedures are the initial puncture of the trachea with subsequent dilatation of the puncture channel. Current meta-analyses of prospectively randomised studies show a lower complication rate than with conventional methods. Furthermore, serious sequelae such as tracheal stenosis are rare in the long-term course. However, conventional operative tracheostomy still has its place, particularly in circumstances where the new methods are contraindicated. [ABSTRACT FROM AUTHOR]

Independent of the type of critical illness, tracheostomized patients have a high risk of developing a dysphagia. This is potentially life-threatening as it can lead to aspiration and pneumonia. It is therefore essential to perform swallowing diagnostics by means of a bolus dyeing test and / or FEES before oral feeding. Since a physiological airflow through the larynx and adequate subglottic pressure are key components of an effective swallowing act, oralisation should be avoided as far as possible with a blocked tracheal cannula.Unabhängig von der Art der kritischen Erkrankung haben tracheotomierte Patienten ein hohes Risiko für die Entwicklung einer Schluckstörung.

Surgery of the trachea is a specialised field in which many disciplines work jointly due to the variety of indications and the extended topography. Not only because of its particular functional importance, but also because of its complex morphology, anatomy and physiology, this organ represents a special therapeutic challenge. A variety of diseases require surgical procedures of the trachea; the therapeutic strategy is influenced both by the disease itself as well as patient-dependent parameters. Regardless of the nature of the underlying disorder, good results require a high level of expertise in airway management, a careful diagnosis and interventional planning as well as an experienced surgical team that masters extended operative techniques. An optimal treatment decision always requires a multidisciplinary assessment of the patient's individual situation by interventional pulmonologists, thoracic surgeons, visceral surgeons, ENT (ear, nose and throat) surgeons and anaesthesiologists.Die Chirurgie der Trachea ist ein Spezialgebiet, in dem aufgrund der Vielzahl von Indikationen und der erweiterten Topografie viele Disziplinen gemeinsam tätig sind. Nicht nur wegen der besonderen funktionellen Bedeutung, sondern auch wegen seiner komplexen Morphologie, Anatomie und Physiologie stellt dieses Organ eine besondere therapeutische Herausforderung dar. Eine Vielzahl von Krankheiten erfordert chirurgische Eingriffe der Trachea – sowohl die Krankheit selbst als auch patientenabhängige Parameter beeinflussen die therapeutische Strategie. Unabhängig von der Art der zugrunde liegenden Erkrankung erfordert es eine hohe Expertise im Luftwegmanagement, eine sorgfältige Diagnose und interventionellen Planung sowie ein erfahrenes OP-Team mit Beherrschung der erweiterten Operationstechniken, um gute Ergebnisse zu erzielen. Zur optimalen Therapieentscheidung ist immer eine multidisziplinäre Bewertung der individuellen Situation durch den interventionellen Pneumologen, den Thoraxchirurgen, den Viszeralchirurgen, HNO-Chirurgen und Anästhesisten erforderlich.

Trachea ,Treatment Outcome ,Quality of Life ,Humans ,Stents ,Tracheoesophageal Fistula - Abstract
A tracheoesophageal fistula is the formation of an abnormal communication between the airway and the esophagus. Acquired tracheoesophageal fistulas can be benign or malignant. The management is either surgical or endoscopic depending on the etiology, size and anatomy of the fistula as well as on the patient's performance status. The interventional treatment of choice is endoscopic stent implantation. In general, tracheoesophageal fistulas in patients with benign conditions are managed surgically. If the patient is unfit for surgery silicone stents should be used because they can be more easily removed after a longer indwelling time compared to metal stents. Malignant fistulas are associated with very limited life expectancy of only a few weeks or months. In this situation fully covered self-expandable metal stents (FC-SEMS) are recommended, whereas surgical treatment approaches can only be considered in individual cases. Depending on the location of the fistula and the presence of an airway stenosis, tracheal stenting, esophageal stenting or parallel stenting of the trachea and the esophagus is carried out. Successful stent placement leads to immediate palliation of symptoms, such as cough or aspiration and results in a higher quality of life. Potential complications are stent migration, bleeding of the upper gastrointestinal tract, arrosion of neighboring organs and vessels with esophageal stents as well as secretion retention and obstruction with displacement of the airway with tracheobronchial stents.

A tracheoarterial fistula (TAF) is an uncommon but life-threatening complication after tracheostomy. Only an immediate and targeted treatment provides a chance to survive.Surgical treatment of TAF.Selective review of the literature and case description.A TAF leads to an acute bleeding complication with displacement of the respiratory tract. The mortality rate is nearly 100% without a surgical intervention. In the literature various interventional and surgical treatment procedures are described. Rapid control of bleeding via manual compression and overinflation of the tracheal cuff are the most important steps of treatment. Subsequent emergency surgery with ligation or resection of the TAF and covering of the tracheal lesion should be performed. Extracorporeal membrane oxygenation (ECMO) and a heart-lung machine can sometimes be necessary.Despite all treatment options the mortality rate of TAF remains high. The critical steps are a quick diagnosis of TAF, securing the airway and immediate bleeding control.

A young man presented with haemoptysis, eight years after foreign body aspiration. The initial evaluation took place in the emergency department of a general hospital. However, neither chest x-ray nor bronchoscopy were performed. Bronchoscopy performed in our hospital revealed a foreign body in right lower lobe bronchus. Extraction failed because it was embedded in granulation tissue. The chronic atelectasis of right lower lobe and recurrent bronchopulmonary infections during the last years were the indication for lobectomy.Ein Patient entwickelt 8 Jahre nach Aspiration eines Fremdkörpers Hämoptysen. Die initiale Diagnostik des damals 14-Jährigen erfolgte in der Notaufnahme eines Hauses der Basisversorgung. Von einer Bronchoskopie und einer radiologischen Diagnostik wurde in dem Fall abgesehen. Bronchoskopisch lässt sich ein Fremdkörper im rechten Unterlappenbronchus darstellen. Aufgrund der entstandenen Vernarbung waren die bronchoskopischen Versuche der Fremdkörper-Bergung frustran. Bei einer chronischen Atelektase des rechten Unterlappens und rezidivierenden bronchopulmonalen Infektionen in den letzten Jahren wurde die Indikation zur Lobektomie gestellt.

Cervical stenosis of the trachea caused by tracheotomy, tumor or without defined reason (idiopathic) can be treated by resection and anastomosis with good early and long-term results. Involvement of the ring cartilage makes the procedure technically demanding and increases the risk of morbidity. We describe our technique of laryngotracheal resection and reconstruction and compare the perioperative results with standard tracheal resection. Between January 2005 and December 2015, we performed about 800 procedures on the trachea including 76 standard cervical tracheal resections and 35 laryngotracheal resection. Resections were carried out with direct anastomosis without intraoperative tracheotomy or intralaryngeal stenting. Patient records were retrospectively analysed for perioperative data. The main cause of stenosis or defect of the trachea and operation was preceding tracheotomy. Idiopathic stenosis, tumors and subglottic stenosis in Wegener disease were less common. There were no disturbances of healing of the anastomosis in any patient. Tracheotomy in the course of treatment for intralaryngeal swelling or recurrent nerve palsy was necessary in 3 (standard) and 2 (laryngotracheal) patients. Postoperative tracheostomy was closed in all patients within 3 months. Pulmonary complications and recurrent nerve palsy occurred in 5/4 and 2/2 of the patients without significant differences between the 2 groups. One patient died in each group from pulmonary complications. The laryngotracheal resection is a relevant part of cervical tracheal surgery. It can be performed without significantly higher morbidity and can restore lung function and quality of voice. Zervikale Tracheastenosen als Folge von Tracheotomien oder Tumoren sowie idiopathischer Genese können in der Regel durch eine Tracheaquerresektion unterhalb des Ringknorpels dauerhaft geheilt werden. Im Falle einer Beteiligung des Ringknorpels erhöhen sich die Komplexität und das Risiko des Eingriffs. Wir berichten über die Technik der laryngotrachealen Resektion und Rekonstruktion und vergleichen in unserem eigenen Patientengut die Ergebnisse der zervikalen Tracheaquerresektion und der laryngotrachealen Resektion in Bezug auf ihre perioperativen Ergebnisse. In unserer Klinik wurden im Zeitraum von 01/2005 bis 12/2015 über 800 Tracheaeingriffe durchgeführt. Davon waren 111 zervikale Trachearesektionen mit 76 Tracheaquerresektionen und 35 laryngotracheale Resektionen. Die Resektion erfolgte immer mit primärer Anastomose ohne Anlage eines intraoperativen Tracheostomas oder einer intralaryngealen Schiene. Die perioperativen Daten wurden retrospektiv aus den Patientenakten erhoben. Bei der Indikationsstellung überwiegt in beiden Gruppen die Stenose oder Defektbildung nach Tracheotomie, gefolgt von idiopathischer Stenose, Tumoren und Morbus Wegener. Es traten keine Wundheilungsstörungen an der Anastomose auf. Postoperative Tracheotomien waren mit 3 bzw. 2 Eingriffen nach Tracheaquer- bzw. laryngotrachealer Resektion selten notwendig. Pulmonale Komplikationen und die N. recurrens-Parese waren mit 5/4 und 2/2 Fällen in beiden Gruppen ähnlich häufig. Kein Patient musste mit einem definitiven Tracheostoma weiterleben. Es verstarb jeweils ein Patient im postoperativen Verlauf. Somit ergab sich kein signifikanter Unterschied in der Komplikationsrate zwischen den beiden Gruppen. Die laryngotracheale Resektion ist ein relevanter Bestandteil der zervikalen Trachearesektion. Sie kann ohne signifikant erhöhte Morbidität durchgeführt werden und erhält so die pulmonale und Stimmfunktion des Patienten auch bei komplexen Stenosen mit Beteiligung des unteren Kehlkopfes.

Anterograde transnasal flexible endoscopy of the pharynx, larynx, and proximal trachea without sedation has been established since the 1990s. Retroflexed endoscopic functional analysis has recently been introduced.Adding retroflexed functional endoscopy from the oral cavity up to the duodenum to anterograde diagnostics allows the precise demonstration of how different factors interact in a complex way, e. g., in case of dysphagia or pathological reflux.A 70-cm-long high-definition endoscope without a channel system is equipped with a 200° retroflexed view, a mm-cm scale, and a roller system. The endoscope can be lengthened, stopped, or shortened during the procedure. Standard positions, viewing directions and display details ensure that findings are comparable. Mastication, food transport and digestion are observed in the unsedated patient.Depending on indication and symptoms, we defined a diagnostic algorithm including three specific pathways: (1) for conditions that originate in the oral cavity, larynx or pharynx, (2) for suspected reflux disease, or for neurological or neuromuscular disorders of food transport, (3) for duodenogastric, gastroesophageal and esophagopharyngeal reflux, as well for benign or malignant tumors.The advantages of functional endoscopy have an impact not only on the medical staff and patients. Its precise and participatory approach is relevant to healthcare, enlarges the diagnostic horizon, and forms a basis for interdisciplinary collaboration.

Lung separation and isolation with accomplished one-lung ventilation plays a key role in the airway management for thoracic surgery. Spectrum of indication contains thoracic surgery, procedure- and patient-dependent factors. Usually lung isolation is achieved with a double-lumen tube or a bronchial blocker. Knowledge in tracheobronchial anatomy is routinely requested for anesthesiologists just as the standard use of flexible fibreoptic bronchoscope. This review would give an overview and discussion about the airway management in patients during thoracic anesthesia with double-lumen tubes and recommendations for the clinical routine.Die Seitentrennung der Lungen mit konsekutiver Ein-Lungen-Ventilation ist der zentrale Bestandteil des Atemwegsmanagements in der Thoraxanästhesie. Das Indikationsspektrum umfasst dabei die thoraxchirurgischen und prozedurbezogenen Notwendigkeiten wie auch die patientenspezifischen Faktoren. Von der Vielzahl der technischen Möglichkeiten der Separation der Lungenflügel bleiben routinemäßig nur die Anwendung des Doppellumentubus oder des Bronchusblockers übrig. Die ausgewiesene Kenntnis der tracheobronchialen Anatomie bis zur Segmentebene durch den Anästhesisten ist ebenso notwendig wie der standardmäßige Einsatz einer flexiblen Fiberoptik. Diese Arbeit gibt grundlegende Empfehlungen für die klinische Routine, stellt eine Übersicht zum derzeitigen Stellenwert im Atemwegsmanagement in der Thoraxanästhesie mit dem Doppellumentubus dar und berücksichtigt kontroverse Diskussionen zu Größe und Design.
