Interscalene nerve blocks are common procedures performed before upper extremity surgeries in order to provide post-op pain relief and improve recovery time. Here we present two cases of patients who underwent a unilateral supraclavicular and bilateral interscalene nerve block, respectively. The first patient had no risk factors but the second presented with a body mass index of 45.5 and a history of symptoms consistent with obstructive sleep apnea but never diagnosed. Both patients experienced some form of respiratory distress diagnosed via changes in chest x-ray and clinical presentation. The mechanism of injury that occurs in these procedures is typically from inadvertent damage to the phrenic nerve. Mild adverse effects in interscalene nerve block are relatively common. However, there is minimal data in regards to performing bilateral interscalene nerve blocks. The purpose of this study is to highlight that severe complication in both high and low-risk patients can occur but may be reduced with a safer approach and more effective communication among multidisciplinary team members.

Bakgrund: Akut respiratorisk svikt är en vanlig sökorsak på akutmottagningar. Studier har visatatt NIV kan minska behovet av intubation och öka chansen för överlevnad hos patienter medsvåra andningsbesvär. Då specialistsjuksköterskan arbetar personcentrerat kan patientensupplevelse höras och därmed kan utfallet av NIV förbättras genom förståelse för patienterserfarenheter. Syfte: Syftet var att beskriva patienters erfarenheter av non-invasiv ventilation vid akutrespiratorisk svikt. Metod: Integrativ litteraturstudie med systematisk litteratursökning i databaserna PubMed,Cinahl och PsychInfo. Resultat: Resultatet baseras på 14 artiklar och är indelat i tre huvudkategorier: Behandlingenspåverkan, Vårdpersonalens påverkan och Psykosocial påverkan. Nio underkategorierpresenteras: Att bli hjälpt av behandlingen, Att uppleva besvär av behandlingen, Att känna stödfrån vårdpersonal, Att vara utlämnad, Att ha behov av information, Att utveckla strategier, Att haett behov av kontroll samt Att bli påverkad av personliga relationer. Slutsats: Patienters erfarenheter av NIV vid akut respiratorisk svikt varierade och både positivaoch negativa upplevelser beskrevs. Att genomgå behandling med NIV försätter patienten i ensårbar situation och om akutsjuksköterskan implementerar principerna för personcentreradomvårdnad kan patienters behov mötas vilket kan förbättra utfallet av behandlingen. / Background: Acute respiratory failure is a common reason for seeking emergency services.Studies have shown that NIV can reduce the need for intubation and increase the chance ofsurvival in patients with severe respiratory distress. As the specialist nurse works person-centred,the patient's experience can be heard and thus the outcome of NIV can be improved throughunderstanding the patients' experiences. Aim: The aim was to describe patients’ experiences of non-invasive ventilation in acuterespiratory failure. Method: Integrative literature study with systematic literature search in the databases PubMed,Cinahl and PsychInfo. Result: The result is based on 14 articles and is divided into three main categories: Impact of thetreatment, Impact of the healthcare staff and Psychosocial impact. Nine subcategories arepresented: Being helped by the treatment, Experiencing discomfort from the treatment, Feelingsupported by healthcare personnel, Being left out, Having a need for information, Developingstrategies, Having a need for control and Being affected by personal relationships. Conclusion: Patients' experiences of NIV in acute respiratory failure varied and both positiveand negative experiences were described. Undergoing treatment with NIV puts the patient in avulnerable situation and if the emergency nurse implements the principles of person-centerednursing, patients' needs can be met, which can improve the outcome of the treatment.

A Distrofia Muscular dos cães Golden Retriever (GRMD) é uma miopatia degenerativa causada pela ausência da proteína distrofina na superfície da membrana da célula muscular. É geneticamente homóloga à distrofia muscular de Duchenne (DMD) que acomete os humanos, portanto, estes cães são considerados modelos experimentais para estudos que buscam tratamentos para pacientes vitimados pela doença. A maior causa de morte na DMD é a insuficiência respiratória ou infecção pulmonar que ocorre em cerca de 75% dos casos. Os músculos respiratórios são sempre afetados e, juntamente com as cifoescolioses e deformidades torácicas, diminuem marcadamente a função respiratória. O padrão respiratório é de respiração rápida e superficial, com volume corrente diminuído, e está associado com a presença de alterações nas pressões parciais dos gases sanguíneos. A complacência pulmonar diminui, resultante de microatelectasias. Os músculos intercostais internos e abdominais, que auxiliam a expiração, também são acometidos, reduzindo a efetividade da tosse e dificultando a eliminação de secreções. Na fase préterminal da doença, nota-se uma redução na pressão parcial de oxigênio arterial associada com a retenção do gás carbônico, podendo observar-se um quadro de cianose, papiloedema e falhas respiratórias. A ventilação nãoinvasiva com pressão positiva (VNIPP) consiste em um método de assistência ventilatória em que uma pressão positiva é aplicada à via aérea do paciente através de máscaras ou outras interfaces sem a utilização da intubação traqueal. Este estudo teve como escopo avaliar possibilidades de terapia respiratória em cães afetados pela GRMD submetidos à VNIPP, identificar os fatores associados ao sucesso ou ao insucesso da VNIPP; caracterizar os padrões de resposta a VNIPP e complicações associadas. Os conhecimentos específicos das modalidades ventilatórias a serem usadas, assim como dos parâmetros ventilatórios a serem empregados na terapia foram fundamentais para a realização deste trabalho. A monitorização das concentrações dos gases sangüíneos, e da saturação de oxigênio, são essenciais para que possam ser estabelecidos parâmetros ventilatórios seguros e confortáveis aos animais e, assim, viabilizar a terapia. No experimento proposto foram estudados cães Golden Retriever, afetados pela distrofia muscular, submetidos à ventilação mecânica não-invasiva com pressão positiva. Para tanto foi consideradas na avaliação respiratória, a gasometria arterial e a oximetria. Apesar do desconforto respiratório e sinais de hipoventilação, clinicamente observado nos animais, não houve confirmação de Insuficiência Respiratória. Portanto concluímos que o suporte ventilatório não-invasivo (Bipap) falhou em demonstrar melhora nas funções respiratórias dos cães da raça Golden Retriever afetados pela distrofia muscular quando usado sob a forma profilática. / The Muscular Dystrophy Golden Retriever dogs (GRMD) is a degenerative myopathy caused by the absence of dystrophin protein on the surface of the membrane of muscle cells. It is genetically counterpart to Duchenne muscular dystrophy (DMD) which affects humans, so these dogs are considered experimental models for studies that seek treatments for patients affected by the disease. The biggest cause of death in DMD is respiratory failure or lung infection that occurs in about 75% of cases. The respiratory muscles are always affected and, together with the cifoescolioses and chest deformities, the markedly reduced respiratory function. The breathing pattern is rapid and superficial, with tidal volume decreased, and is associated with the presence of changes in the partial pressure of blood gases. The lung compliance decreases, resulting from microatelectasias. The intercostal muscles and internal abdominal, which help the expiration, are also affected, reducing the effectiveness of cough and hampering the removal of secretions. In the preterminal disease, there is a reduction in the partial pressure of oxygen blood associated with the retention of carbon dioxide, with a framework of cyanosis, papilloedema and respiratory failure. The non-invasive ventilation with positive pressure (VNIPP) is a method of ventilatory assistance at a positive pressure that is applied to air the patient through masks or other interfaces without the use of intubation. This study was to objective evaluate the potential of respiratory therapy in dogs affected by GRMD submitted to VNIPP, identify the factors associated with the success or failure of VNIPP; characterize the patterns of response to VNIPP and associated complications. The specific knowledge of how to use ventilation and the ventilatory parameters to be used in therapy were fundamental for this work. The monitoring of blood concentrations of the gases, and the saturation of oxygen, are essential in order to be established ventilatory parameters safe and comfortable for animals and thereby facilitate the therapy. In the proposed experiment studied dog Golden Retriever, affected by muscular dystrophy, submitted to non-invasive mechanical ventilation with positive pressure. To do so was considered in assessing breathing, blood gases and oximetry. Despite the signs of respiratory discomfort and hypoventilation, clinically observed in animals, there was no confirmation of respiratory failure. So we find that the non-invasive ventilatory support (Bipap) failed to show improvement in respiratory functions of the breed dogs Golden Retriever affected by muscular dystrophy when used in the form prophylactic.

Introdução: A insuficiência renal (IRen) aguda ou renal crônica podem levar a complicações respiratórias, que podem culminar com insuficiência respiratória aguda (IRpA), severa hipoxemia e alterações de mecânica respiratória (MR). O tratamento hemodialítico, pode desencadear um processo inflamatório pulmonar entretanto, a correção da hipervolemia que proporciona, pode melhorar a IRpA. O objetivo deste estudo foi avaliar a influência da hemodiálise (HD) na MR de pacientes com IRen sob ventilação mecânica invasiva (VMI). Materiais e Métodos: Pacientes com IRen, idade 18 a 75 anos, em VMI e em HD. Parâmetros analisados: clínicos gerais, laboratoriais (hemograma, gasometria arterial, função renal), características da HD e MR (complacência estática e dinâmica, e resistência do sistema respiratório). Os parâmetros foram analisados antes do início da HD e 4 horas após seu início. Resultados: (média ± DP) Foram analisados 37 pacientes, idade 51 ± 17 anos. Houve perda de peso, e melhora dos parâmetros laboratoriais (p < 0,05) exceto a PaO2 e a saturação de O2. A HD não alterou a pressão arterial e nem a MR, porém o delta da complacência dinâmica apresentou correlação com o delta de creatinina (p = 0,02). Conclusão: A HD por 4 horas não altera a MR de pacientes sob VMI. / Introduction: Renal failure (RF), acute or chronic, can induce respiratory complications that can evolve to acute respiratory failure (ARpF), hypoxemia and severe changes in respiratory mechanics (RM). Hemodialysis (HD) can produce pulmonary inflammation and worse the ARpF. On other hand, HD corrects hypervolemia and thus can improve the ARpF. The objective of this study was evaluating the HD role in RM of RF patients in use of invasive mechanical ventilation (IMV). Materials and Methods: Patients with RF, age 18 to 75 years, in use of IMV and HD. Analyzed parameters: age, gender, HD characteristics, respiratory and renal laboratory tests, and RM evaluation (static and dinamic compliance and resistence). Parameters were evaluate before HD and 4 hours after it started. Results (mean ± SD): We studied 37 patients, age 51 ± 17 years. During HD the patients lost body weight and presented an improvement in pulmonary and renal parameters (p < 0.05) except for PaO2 and arterial O2 saturation (p > 0.05). HD did not induce hemodynamic instability. There was correlation (p = 0.02) between the changes in plasma creatinine and the changes in dynamic compliance. Conclusion: HD for 4 hours did not modify respiratory mechanics in patients in use of IMV.

In recent years, several new oral anticancer drugs have been approved, many via an accelerated approval process. These new agents have the potential for drug interactions, but lack of familiarity with these drugs by clinicians may increase the risk for drug interactions. We describe an interaction between the new anticancer agent idelalisib (CYP 3A4 inhibitor) and diazepam (CYP 3A4 substrate) that resulted in altered mental status and type II respiratory failure resulting in hospitalization. After discontinuation of both agents, the patient recovered quickly. Idelalisib was reinitiated after discharge. Lorazepam was substituted for diazepam since it is not metabolized via CYP 3A4. Both agents were tolerated well thereafter. This interaction was only flagged by two of four commonly used drug interaction databases. Clinicians should exercise caution with initiating new oral anticancer agents and consider the potential for drug interactions without solely relying on drug interaction databases.

Klinischer Hintergund: Patienten mit akutem Lungenversagen (Acute respiratory distress syndome, ARDS) bedürfen intensivmedizinischer Behandlung. Die maschinelle Beatmung spielt dabei eine zentrale Rolle. Um einer zusätzlichen ventilatorassoziierten Lungenschädigung (ventiator induced lung injury, VILI) vorzubeugen, wird vom ARDS network die Beatmung mit niedrigem Atemzugvolumen empfohlen. Das Zulassen von Spontanatmung und Variabilität in der Druckunterstützung sind weitere Beatmungsstrategien, welchen in verschiedenen Studien positive Effekte im Bezug auf pulmonale Entzündungsreaktion, Schädigung des Lungengewebes und Gasaustausch zugeschrieben werden. Eine weit verbreitete Form der assistierten Spontanatmung ist die druckunterstützte Beatmung (Pressure Support Ventilation, PSV), bei der jede inspiratorische Atembemühung mit stets demselben Druck unterstützt wird. Es resultiert eine relative geringe Atemvariabilität. Eine weitere häufig angewandte Form der assistierten Spontanatmung ist die proportionale Druckunterstützung (Proportional Assist Ventilation, PAV). Hier verhält sich das Maß der Druckunterstützung proportional zu den inspiratorischen Bemühungen des Patienten. Entsprechend führt PAV, abhängig von der intrinsischen Variabilität des Patienten, zu einer höheren Variabilität an Atemzugvolumen und Atemfrequenz. Eine neuere Form der assistierten Spontanatmung ist die variable druckunterstützte Beatmung (noisy PSV), welche ebenfalls die Variabilität von Atemzugvolumen und Atemfrequenz erhöht. Im Unterschied zu PAV ist die Variabilität der Druckunterstützung extrinsisch und wird durch das Beatmungsgerät vorgegeben. Fragestellung /Hypothesen: Die vorliegende Studie untersucht die Therapieeffekte von noisy PSV, PAV und PSV auf pulmonale Entzündungsreaktion, Schädigung des Lungengewebes sowie Ventilationsverteilung im ARDS-Modell Surfactant depletierter Schweinelungen. Folgende Hypothesen wurden dazu formuliert: 1. Unter Noisy PSV zeigt sich eine Umverteilung der regionalen Ventilation von ventral nach dorsal. 2. Unter Anwendung von noisy PSV kommt es zu einer geringeren Schädigung des Lungengewebes im Vergleich zu PAV und PSV. 3. Noisy PSV kann die Entzündungsreaktion gegenüber PAV und PSV senken. Material und Methoden: 24 Jungschweine mit einem mittleren Körpergewicht von 31,3 kg (26,8 – 34,4 kg) wurden anästhesiert, intubiert und mechanisch beatmet. Die Lungenschädigung wurde mittels wiederholter Kochsalzlavagen herbeigeführt bis ein stabiles Verhältnis von arteriellem Sauerstoffpartialdruck zur inspiratorischen Sauerstofffraktion von unter 200 mmHg erreicht war. Dies entspricht der Definition eines moderaten ARDS. Nach Spontanisierung der Atmung folgte die Randomisierung der Versuchstiere zu einer der drei assistierten Beatmungsmodi noisy PSV, PAV oder PSV. Die Beatmung erfolgte jeweils mit einem mittleren Atemzugvolumen von 6 ml /kg KG über einen Zeitraum von sechs Stunden. Es wurden impedanztomographische Messungen zur regionalen Ventilationsverteilung durchgeführt. Untersuchungen zur pulmonalen Entzündungsreaktion und histologischen Schädigung des Lungengewebes wurden post mortem vorgenommen Zusätzlich erfolgten Messungen zu Hämodynamik, Atemmechanik und Gasaustausch. Außerdem wurden Atemmuster und die Variabilität der Atmung analysiert. Die Ergebnisse dieser Messungen sind jedoch nicht Gegenstand dieser Dissertation und werden an anderer Stelle diskutiert. Ergebnisse: PAV, nicht jedoch noisy PSV, führte zu einer Umverteilung der regionalen Ventilation von zentral nach dorsal im Vergleich zu PSV. Für den kumulierten DAD Score ließen sich keine signifikanten Unterschiede zwischen den Gruppen nachweisen. In schwerkraftunabhängigen Lungenabschnitten zeigten sich weniger interstitielles Ödem für PAV und noisy PSV im Vergleich zu PSV sowie weniger Hämorrhagie für PAV und PSV im Vergleich zu noisy PSV. Auch ergab sich ein geringeres Maß an Überdehnung für PAV im Vergleich zu PSV. In schwerkraftabhängigen Lungenabschnitten kam es unter noisy PSV zu einer Reduktion von interstitiellem Ödem im Vergleich zu PSV. Insgesamt, für schwerkraftabhängige und schwerkraftunabhängige Regionen zusammen betrachtet, zeigten sich weniger Hämorrhagie für PAV im Vergleich zu noisy PSV sowie weniger interstitielles Ödem für PAV und noisy PSV im Vergleich zu PSV. Unabhängig von der Therapieform war weniger Hämorrhagie in schwerkraftunabhängigen im Vergleich zu schwerkraftabhängigen Lungenabschnitten zu beobachten. Für den Gehalt an mRNA für IL-1, IL-6, IL-8, TNF-α, TGF-ß, Amphiregulin und Tenascin-c im Gewebe sowie für die Konzentration TNF-α und IL-8 im Lungengewebe, TNF-α im Blutplasma sowie IL-8 in den Proben der BAL ließen sich ebenso keine signifikanten Unterschiede zwischen den Gruppen nachweisen wie für die Proteinkonzentration in der BAL-Flüssigkeit und die Wet-/Dry-Ratio des Lungengewebes. Schlussfolgerungen: In diesem Modell des akuten Lungenversagens am Schwein resultierte eine 6-stündige Beatmungstherapie mit variabler Druckunterstützung, proportionaler Druckunterstützung oder konstanter Druckunterstützung in einer vergleichbaren Schädigung des Lungengewebes ohne wesentliche Unterschiede in der Entzündungsreaktion.

Non-invasiv ventilation är en vanligt förekommande behandling för patienter som söker akutsjukvård med akut respiratorisk svikt. Behandlingen startas ofta på akutmottagningen och fortsätter därefter på intensiv-, intermediär- eller vanlig vårdavdelning. Behandlingen kan av patienter upplevas både intensiv och betungande och ett betydande problem är att patienten inte tolererar behandlingen.  Syftet var att beskriva patienters erfarenheter av non-invasiv ventilator vid akut respiratorisk svikt. Metoden var en allmän litteraturöversikt med systematiskt tillvägagångssätt. Systematiska sökningar utfördes i databaserna PubMed, CINAHL och PsychInfo. Sammanlagt inkluderades 15 kvalitativa och kvantitativa vetenskapliga artiklar publicerade mellan år 2012–2019 till litteraturöversikten. Inkluderade artiklar analyserades med en integrerad metod.  Analysen ledde fram till två huvudkategorier och sex underkategorier. Resultatet påvisade förekomst av både fysiska och psykiska aspekter. Sammanfattningsvis var erfarenheter av negativ art vanligast förekommande och kunde karakteriseras av symtom på ångest, smärta och klaustrofobi. Positiva upplevelser var upplevelser av förbättrat andningsarbete, känslor av hopp och säkerhet samt att få en chans till ett fortsatt liv. Resultatet visade även hur personalen påverkar patienters erfarenheter av non-invasiv ventilatorbehandling, där bristfällig delaktighet är en tydligt hämmande faktor och hög kunskapsgrad samt erfarenhet hos personalen en framstående främjande faktor.  Slutsatsen blev att patienter många gånger upplever en majoritet av negativa symtom samtidigt som de befinner sig i en särskilt utsatt och sårbar situation. Behandlingens utfall påverkas av patientens erfarenheter men med hjälp av ökade kunskaper och ett personcentrerat arbetssätt hos hälso- och sjukvårdspersonalen kan den non-invasiva ventilatorbehandlingen optimeras. / Non-invasive ventilation is a common treatment for patients seeking emergency care with acute respiratory failure. The treatment is often initiated at the emergency department and further continues in the intensive- or intermediate care unit, or on a regular ward. The treatment can be experienced by patients as intensive and burdensome, and a significant problem is that the patient can’t tolerate the treatment.   The aim was to describe patients’ experiences of non-invasive ventilation in acute respiratory failure. The method was a general literature review with a systematic approach. Systematic searches were carried out in the PubMed, CINAHL and PsychInfo databases. A total of 15 qualitative and quantitative articles published between the years 2012–2019 was included for the literature review. The included articles were analyzed in an integrated method.  The analysis led to two main categories and six subcategories. The results showed occurrences of both physical and psychological aspects. In summary, negative experiences were the most common and could be characterized by symptoms of anxiety, pain and claustrophobia. Positive experiences were experiences of improved work of breathing, feelings of hope and safety and to be given a chance to a continued life. The results also showed how healthcare personnel affect patients' experiences of non-invasive ventilation, where decreased participation was a clearly inhibiting factor and high levels of knowledge and experience in the personnel was an eminent promoting factor.  The conclusion was that patients often experience a majority of negative symptoms and at the same time being in a particularly vulnerable situation. Treatment outcomes are affected by patients' experiences, but with the use of increased knowledge and a person-centered approach by the healthcare personnel, the non-invasive ventilation treatment can be optimized.
