RESUMEN

Abstract Background Arterial hypertension affects around 30% of the Brazilian adult population, showing a direct and progressive relationship with an increased risk of cardiovascular diseases (CVDs). In this context, adjustments in the calibration and physical constitution of sphygmomanometers are essential conditions for obtaining correct blood pressure (BP) measurements. Objectives Analyze the profile and quality of sphygmomanometers used in various sectors of a health education institution in Belo Horizonte, Minas Gerais. Methods The present study conducted a cross-sectional, observational, and non-interventional study to assess adherence to various quality parameters of the sphygmomanometers available in the outpatient clinic, emergency department, and ward of an educational institution in the municipality of Belo Horizonte. Results We analyzed 78 devices, in which high rates of adherence were identified for velcro/pins, 93.5% (73/78); bulbs/rubbers, 92.1% (70/76); valves, 93.4% (71/76); the seal of the National Institute of Metrology, Quality, and Technology (INMETRO), 97.4% (76/78); and the clock, 92.1% (70/76). However, these parameters showed no statistical significance. Institutions (hospital/outpatient clinic) recorded higher calibration rates, 75% (39/52, p<0.001), in accordance with the deadlines stipulated by INMETRO, and the cuff/equipment compatibility showed its highest value (52%) among students (32/61, p = 0.004). Conclusion Our study showed that 38.4% (30/78) of the devices did not presented some type of inadequacy, with outpatient-owned devices had the highest compliance rate (p = 0.015). These findings are worrisome, as they can lead to inaccurate BP measurements.

RESUMEN

Objective The present study aims to evaluate the influence of different positioning of the hip femoral prosthesis on the stress and strain over this implant. Methods A femoral prosthesis (Taper - Víncula, Rio Claro, SP, Brazil) was submitted to a stress and strain analysis using the finite element method (FEM) according to the International Organization for Standardization (ISO) 7206-6 Implants for surgery - Partial and total hip joint prostheses - Part 6: Endurance properties testing and performance requirements of neck region of stemmed femoral components standard. The analysis proposed a branch of the physical test with a +/- 5° angle variation on the standard proposed for α and ß variables. Results The isolated +/- 5° variation on the α angle, as well as the association of +/- 5° variation on the α and ß angles, presented significant statistical differences compared with the control strain ( p = 0.027 and 0.021, respectively). Variation on angle ß alone did not result in a significant change in the strain of the prosthesis ( p = 0.128). The stem positioning with greatest implant strain was α = 5° and ß = 14° ( p = 0.032). Conclusion A variation on the positioning of the prosthetic femoral stem by +/- 5° in the coronal plane and/or the association of a +/- 5° angle in coronal and sagittal planes significantly influenced implant strain.

RESUMEN

ABSTRACT BACKGROUND: Leg length discrepancy (LLD) may play a key role in exercise biomechanics. Although the Podoprint platform has been used in dynamic pressure studies, there are no data regarding the reliability and repeatability of dynamic measurements under simulated LLD conditions. OBJECTIVES: To determine the intra and intersession repeatability and reliability of dynamic parameters of the Podoprint pressure platform under simulated LLD conditions. DESIGN AND SETTING: Observational cross-sectional study at a public university. METHODS: Thirty-seven healthy volunteers participated in this study. LLD was simulated using ethyl vinyl acetate plantar lifts with heights of 5 mm, 10 mm, 15 mm and 20 mm located under the right shoe of each volunteer. The procedure was performed to capture the dynamic parameters of each participant under five different simulated LLD conditions. Stance time, mean pressure and peak pressure measurements were registered in three trials for each foot and each LLD level. Data were collected during two separate testing sessions, in order to establish intrasession and intersession reliability. RESULTS: The intraclass correlation coefficients (ICCs) for intrasession reliability ranged from 0.775 to 0.983 in the first session and from 0.860 to 0.985 in the second session. The ICCs for intersession reliability ranged from 0.909 to 0.990. Bland-Altman plots showed absence of systematic measurement errors. CONCLUSIONS: The results from this study indicate that the Podoprint platform is a reliable system for assessing dynamic parameters under simulated LLD conditions. Future studies should evaluate plantar pressures under LLD conditions, in association with exercise, biomechanics and musculoskeletal disorders.

RESUMEN

OBJECTIVE: To describe the development of a wheelchair repair registry from large datasets to attain an understanding of wheelchair failures and service repairs. DESIGN: Guidelines for registry development were applied and anchored around Labor-Tracker, a web-based information management system for wheelchair suppliers to manage and track wheelchair repairs. The registry was designed using online analytical processing, allowing for rapid data queries from multiple dimensions that enable complex data analysis and discovery. SETTING: The Wheelchair Repair Registry (WRR) was developed through an industry and academic collaboration whereby repair data were collected in the field, entered into the Labor-Tracker system, deidentified, and then transferred to the registry and made available for analyses. PARTICIPANTS: Wheelchair supplier service technicians reported data from repair services provided to individuals who use power wheelchairs, manual wheelchairs, and scooters. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Wheelchair failure and repair data, including variables related to scheduling, equipment information (eg, manufacturer, model, serial number, purchase date), labor, parts, and reasons for repairs. RESULTS: The WRR was developed to analyze wheelchair repairs and failures from the Labor-Tracker system. Currently, the registry has more than 60,000 repairs conducted on more than 5000 wheelchair devices from 25 manufacturers. The devices include 60% power wheelchairs, 35% manual wheelchairs, and 5% scooters. CONCLUSIONS: The WWR creates opportunities to apply large-data analytical methodologies that will serve to inform quality standards, practice, equipment selection, preventative maintenance routines, product design, and policy.

RESUMEN

BACKGROUND: Reach-grasp movements are motor components commonly affected after stroke and directly related to the independence of these individuals. Evaluations of these activities can be performed using clinical instruments and assessed by detailed and costly kinematic analyses. The aim of this study was to develop an analysis of reach-grasp movements in post-stroke patients using a simple, inexpensive, and manageable instrument. RESULTS: A Mann-Whitney test was used to compare paretic and non-paretic limb motor performance. A statistically significant difference was found between the variables of total time (p = 0.02) and speed to reach target 3 (p = 0.04) for task 1, while in task 2 significance was found only in the aspect of speed to reach target 2 (p = 0.04). The correlation between clinical tests and variables of tasks was then performed using Spearman's rank correlation coefficient. At task 1, when compared with the REACH instrument, the close target sub-item; there was a high positive correlation between the parameters of total time (p = 0.028), target velocity 3 (p = 0.028), and target acceleration 3 (p = 0.028). Another instrument that showed a high positive correlation with the target time 3 (p = 0.01) and target acceleration 3 (p = 0.028) variables was the Box and Block Test. When correlated, the data between the task 2 variables and clinical instruments did not present statistically significant data. CONCLUSION: Our instrument-the Temporal Data Acquisition Instrument-TDAI-fulfilled the expected objectives and can be used as an option to evaluate the movements of reach and grasp of upper limb post-stroke, using an easy and fast application, without the need for calibration. Trial registration Trial Registration: Research Ethics Committee of the Trairi School of Health Sciences-Number 2.625.609, approved on April 13, 2018; Brazilian Registry of Clinical Trials-RBR-4995cr approved on July 4, 2019 retrospectively registered (http://www.ensaiosclinicos.gov.br/rg/RBR-4995cr/).

RESUMEN

PURPOSE: The aim of our study is to compare the mechanical resistance of two screw configurations in fixating type II Pauwels femoral neck fractures. METHODS: Fifteen synthetic models of femur bones in young adults were divided into three equal groups: intact (G1), models with fixation of a 5.0-mm failure zone created in the posterior cortex of the femoral neck using an L-shaped screw arrangement (G2, n = 5), and models with an identical failure zone fixated using an inverted triangle assembly (G3, n = 5). Model strength (axial loading) and rotational deviation of the fragments were load-tested until a 5.0-mm displacement was reached (step 1) and then until failure, here considered as 10.0 mm displacement in G2 and G3 or femoral neck fracture in G1 (step 2). RESULTS: In step 1, the mean resistance in G1 was 1593 N (standard deviation [SD] of 62 N); this value in G2 was 1261 N (SD 49 N) and in G3 was 1074 N (SD 153 N). During step 2, the value for G1 was 2247 N (SD 84 N), for G2 was 1895 N (SD 69 N), and for G3 was 1523 N (SD 280 N). G3 (the inverted triangle assembly) showed a significantly lower maximum load than the group using the L-shaped assembly (G2) and the control group (G1), which was significant using Kruskal-Wallis analysis of variance (p = 0.002). CONCLUSION: Under test conditions in synthetic bone, fixation using a L-shaped screw assembly provides greater mechanical resistance than an inverted triangle assembly.

RESUMEN

Resumo A utilização de cateteres totalmente implantáveis no tratamento quimioterápico constitui uma necessidade que acarreta o risco de múltiplas complicações, algumas inerentes à inserção do dispositivo e outras relacionadas ao próprio cateter. Relatamos três casos nos quais o cateter apresentou-se desacoplado de seu respectivo reservatório. No primeiro caso, ocorreu a desconexão do cateter de seu respectivo reservatório, e nos outros dois casos, verificou-se a fragmentação do cateter. Em todos os casos, foi necessária a retirada endovascular do cateter. Tal desfecho é apontado como raro, mas costuma estar presente na maioria das revisões e traz consigo o risco de complicações graves, ainda que frequentemente seja assintomático. É desejável o acompanhamento de pacientes que possuem tais cateteres a fim de que se possa detectar precocemente tais complicações e compreender os fatores que determinam o aparecimento dessas situações.

Abstract Use of totally implantable catheters for chemotherapy treatment is a necessity, but one which brings with it risks of multiple complications, some inherent to insertion of the device and others related to the catheter itself. We describe three cases in which the catheter became disconnected from its reservoir. In the first case, the catheter became completely detached from its reservoir and in the second and third cases the catheter itself underwent fragmentation. In all three cases it was necessary to withdraw the endovascular catheter. This event is described as rare, but it tends to be present in the majority of reviews and it is associated with the risk of serious complications, even though it is often asymptomatic. It is advisable to follow-up patients who have these catheters implanted in order to detect these complications early and to enable understanding of the factors that cause these situations to occur.

RESUMEN

OBJECTIVE: To investigate the frequency and types of wheelchair repairs and associated adverse consequences. DESIGN: Convenience cross-sectional sample survey. SETTING: Nine Spinal Cord Injury Model Systems Centers. PARTICIPANTS: People with spinal cord injury who use a wheelchair >40h/wk (N=591). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Number of repairs needed and resulting adverse consequences, number and types of repairs completed, and location where main repair was completed in the previous 6 months. RESULTS: There were 591 participants responded to the survey, 63.8% (377/591) of them needed ≥1 repair; of these, 27.6% (104/377) experienced ≥1 adverse consequence, including 18.2% (69/377) individuals who were stranded. Of those who needed repairs, 6.9% did not have them completed (26/377). Repairs completed on the wheels and casters were the most frequent repair to manual wheelchairs, whereas repairs to the electrical and power and control systems were the most frequent type of repair on power wheelchairs. Forty percent (79/201) of manual wheelchair users reported completing repairs at home themselves compared with 14% (21/150) of power wheelchair users. Twelve percent of the variance in the odds of facing an adverse consequence because of a wheelchair breakdown can be described as a function of occupation, funding source, and type of wheelchair. CONCLUSIONS: Wheelchair repairs are highly prevalent. There are differences in types of repairs and who completes the repairs based on the type of wheelchair. Wheelchair breakdowns result in adverse consequences for users, and there is a deficit between repairs needed and those completed, highlighting the need for interventions that address these problems.

Sua distribuição, porém, foi interrompida após aobservação de exteriorização dos condutores por falha do isolante em diversos casos de mau funcionamento.Esses cabos-eletrodos foram classificados como classe I de recall pelo Food and Drug Administration. Diversosestudos foram realizados desde então para se determinar a incidência e a prevalência de extrusão dos condutores epara avaliar sua correlação com falha elétrica. Também tem sido estudado o melhor método de rastreio e como seconduzir os pacientes portadores desses cabos-eletrodos.

The cardioverter-defibrillator leads with Riata silicone coating and Riata ST were widely deployed between 2003 and 2010. Its distribution, however, was discontinued after observation of externalization of conductors due to insulation failure in several cases of malfunction. These leads were classified as Class I Recall by the Food and Drug Administration. Several studies have been performed since then to determine the incidence and prevalence of extrusion of the conductors and to evaluate their correlation with electrical failure. The best screening method and how to conduct patients with these leads have also been investigated.

RESUMEN

El síndrome de Twiddler es una complicación infrecuente de los dispositivos de estimulación eléctrica cardíaca; a pesar de su rareza merece ser tenido en cuenta al evaluar pacientes con sospecha de disfunción del marcapasos. Presentamos el caso de un paciente de 62 años portador de marcapasos biventricular quien ingresó al Hospital Universitario San Vicente Fundación por insuficiencia cardíaca descompensada debida a síndrome de Twiddler. Los síntomas se resolvieron con el implante de una nueva terminal de resincronización cardíaca.

Twiddler's syndrome is a rare complication of cardiac conduction devices; despite its low frequency, it should be considered when evaluating patients with suspicion of pacemaker's dysfunction. We report the case of a 62 year old man who consulted Hospital Universitario San Vicente Fundación, in Medellín, Colombia, with decompensated heart failure due to dislodgement of the left ventricle lead of his recently implanted biventricular pacemaker. The patient improved with the placement of a new device.

RESUMEN

Objective: Discomfort and noncompliance with noninvasive ventilation (NIV) interfaces are obstacles to NIV success. Total face masks (TFMs) are considered to be a very comfortable NIV interface. However, due to their large internal volume and consequent increased CO2 rebreathing, their orifices allow proximal leaks to enhance CO2 elimination. The ventilators used in the ICU might not adequately compensate for such leakage. In this study, we attempted to determine whether ICU ventilators in NIV mode are suitable for use with a leaky TFM. Methods: This was a bench study carried out in a university research laboratory. Eight ICU ventilators equipped with NIV mode and one NIV ventilator were connected to a TFM with major leaks. All were tested at two positive end-expiratory pressure (PEEP) levels and three pressure support levels. The variables analyzed were ventilation trigger, cycling off, total leak, and pressurization. Results: Of the eight ICU ventilators tested, four did not work (autotriggering or inappropriate turning off due to misdetection of disconnection); three worked with some problems (low PEEP or high cycling delay); and one worked properly. Conclusions: The majority of the ICU ventilators tested were not suitable for NIV with a leaky TFM. .

Objetivo: O desconforto e a falta de adaptação às interfaces de ventilação não invasiva (VNI) são obstáculos ao sucesso da VNI. A máscara facial total (MFT) é uma interface de VNI considerada muito confortável. No entanto, devido a seu grande volume interno e, consequentemente, ao aumento da reinalação de CO2, a MFT tem orifícios que permitem vazamentos proximais para melhorar a eliminação de CO2. É possível que os ventiladores usados na UTI não compensem esse vazamento adequadamente. Neste estudo, buscamos determinar se ventiladores de UTI com módulo de VNI podem ser usados com MFT com grandes vazamentos. Métodos: Estudo em simulador mecânico conduzido em um laboratório universitário de pesquisa. Oito ventiladores de UTI equipados para realizar VNI e um ventilador específico para VNI foram conectados a uma MFT com grandes vazamentos. Todos foram testados com dois níveis de positive end-expiratory pressure (PEEP, pressão expiratória final positiva) e três níveis de pressão de suporte. As variáveis analisadas foram disparo do ventilador, ciclagem, vazamento total e pressurização. Resultados: Dos oito ventiladores de UTI, quatro não funcionaram (autodisparo ou desligamento inapropriado por detecção incorreta de desconexão), três funcionaram com alguns problemas (valores baixos de PEEP ou grande atraso na ciclagem do ventilador) e apenas um funcionou adequadamente. Conclusões: A maioria dos ventiladores de UTI testados mostrou-se inadequada para VNI com MFT com grandes vazamentos. .

RESUMEN

OBJECTIVE: To determine what factors have a significant influence on the performance of medical device maintenance outsourcing, and to determine how the performance of external governance structures differs depending on whether a hospital is private or public. METHODS: This was a longitudinal study of 590 maintenance transactions at 20 hospitals in Bogotá, Colombia, involving 764 medical devices and 72 maintenance service providers. Maintenance performance data (i.e., turn-around time in hours; TAT) for the service providers (either in-house or outsourced) were primarily collected over a 20-month period, from December 2009-August 2011, by means of a monitoring procedure; then, a hazards model was run. RESULTS: The availability of specific repair parts, in-stock, in the city in which the medical devices were located, had a positive impact on the performance of both internal and external governance structures. Online service also had a positive impact on both, with a stronger positive impact on the performance of internal governance than on that of external governance. For transactions governed by external structures, better performance was seen in private hospitals than in public ones. In public health institutions, internal governance showed better performance than external governance. Both internal and external governance structures showed better performance in private healthcare institutions than in public ones. CONCLUSIONS: In public health institutions, internal governance shows better performance than external governance; this suggests that healthcare managers should reconsider the trend to eliminate in-house maintenance service staff in public healthcare institutions.

OBJETIVO: Establecer los factores que influyen significativamente en el desempeño del mantenimiento de los dispositivos médicos mediante contratación externa, y determinar cómo difiere el desempeño de las estructuras externas de gobernanza según un hospital sea privado o público. MÉTODOS: Se realizó un estudio longitudinal de 590 transacciones de mantenimiento en 20 hospitales de Bogotá (Colombia), que incluyeron 764 dispositivos médicos y 72 proveedores de servicio de mantenimiento. Por medio de un procedimiento de vigilancia, se recopilaron principalmente datos de desempeño del mantenimiento (es decir, el plazo de entrega en horas) por parte de los proveedores del servicio (ya fuera este interno o externalizado) durante un período de 20 meses, desde diciembre del 2009 a agosto del 2011; a continuación, se aplicó un modelo de riesgos. RESULTADOS: La disponibilidad de piezas de repuesto específicas en existencia en la misma ciudad en que se ubicaban los dispositivos médicos tuvo una repercusión positiva sobre el desempeño de ambas estructuras de gobernanza, la interna y la externa. El servicio en línea también tuvo una repercusión positiva en el desempeño de ambas estructuras; pero esta repercusión fue más intensa en el desempeño de la gobernanza interna que en el de la externa. En cuanto a las transacciones regidas por estructuras externas, se observó un mejor desempeño en los hospitales privados que en los públicos. En las instituciones de salud pública, la gobernanza interna mostró un mejor desempeño que la externa. Ambas estructuras de gobernanza mostraron un mejor desempeño en las instituciones de atención de salud privadas que en las públicas. CONCLUSIONES: En las instituciones de salud pública, la gobernanza interna muestra un mejor desempeño que la externa; ello indica que los gerentes de atención de salud deben reconsiderar la tendencia a eliminar al personal de los servicios de mantenimiento interno de las instituciones públicas de atención de salud.

OBJETIVO: Avaliar as condições de uso dos esfigmomanômetros em hospitais públicos e privados. MÉTODOS: Estudo descritivo de abordagem- quantitativa realizado em quatro hospitais de grande porte do Estado de São Paulo, no período entre 2009 e 2010. Os manômetros aneroides foram- testados contra manômetro de mercúrio calibrado. Foram considerados descalibrados quando as diferenças foram > a 4 mmHg. RESULTADOS: Foram avaliados 162 esfigmomanômetros, (78 de um hospital público e 84 de instituições filantrópicas e privada) e 98,1% eram do tipo aneróide.- Verificou-se que 56,2% dos manômetros estavam descalibrados (48,6% do hospital privado e 63,1% dos hospitais públicos). Analisando-se as- médias das diferenças negativas da descalibração, houve diferença significativa entre os manômetros do hospital privado e os dos hospitais públicos- (-6,14±2,66 mmHg vs -8,97±6,74 mmHg, respectivamente, p<0,05). Observou-se ainda que em 70,2% não era feita avaliação periódica; 26,7%- tinham extensão de borracha envelhecida; 20,5% das válvulas apresentaram vazamento; e 27% dos manômetros não estavam com o ponteiro na- marca zero. CONCLUSÃO: A descalibração dos esfigmomanômetros aneróides foi expressiva e pode acarretar avaliação incorreta da pressão arterial.

OBJECTIVE: To evaluate the conditions of sphygmomanometers in use at public and private hospitals. METHODS: A descriptive study using a quantitative- approach, undertaken in four major hospitals in the State of São Paulo, in the period between 2009 and 2010. The aneroid manometers- were tested against a calibrated mercury manometer. They were considered out of calibration when the differences were > 4 mmHg. RESULTS: We assessed 162 sphygmomanometers (78 in a public hospital and 84 from philanthropic and private institutions) and 98.1% were of the aneroid type.- It was verified that 56.2% of the manometers were not calibrated (48.6% of private hospitals and 63.1% of public hospitals). Analyzing the mean- differences of negative decalibration, there was a significant difference between the manometers of the private hospital and the public hospitals (-6.14- ± 2.66 mmHg vs. -8.97 ± 6.74 mmHg, respectively, p <0.05). It was also observed that in 70.2% there was no periodic evaluation made, 26.7% had- aged rubber extension, 20.5% presented leaking valves, and 27% of the manometers did not rest with the pointer on the zero mark. CONCLUSION: The decalibration of the aneroid sphygmomanometers was significant and may lead to incorrect evaluation of blood pressure.

RESUMEN

JUSTIFICATIVA E OBJETIVOS: O manejo da via aérea difícil em cirurgia torácica é um assunto peculiar, devido às exigências da ventilação monopulmonar com o uso de tubos de duplo-lúmen. O auxílio da broncoscopia flexível é de enorme importância, porém nem sempre está disponível. O objetivo deste relato é descrever um caso de intubação orotraqueal seletiva retrógrada na ausência de equipamento de endoscopia específico para o procedimento. RELATO DO CASO: Paciente com história prévia de retossigmoidectomia internou-se para abordagem cirúrgica de lesão pulmonar por toracotomia direita. Avaliação anestésica pré-operatória não revelava particularidades nem na história clínica nem no exame físico. Após indução anestésica e ventilação com máscara facial, à laringoscopia direta duas tentativas de intubação orotraqueal mostraram-se inefetivas devido à difícil visualização das pregas vocais (Cormack-Lehane grau III). Em função da indisponibilidade de material específico para intubação seletiva endoscópica optou-se pela técnica retrógrada utilizando tubo de duplo-lúmen. O paciente foi extubado na sala cirúrgica logo após o término da cirurgia e não apresentou complicações decorrentes da técnica alternativa. CONCLUSÕES: A intubação orotraqueal seletiva retrógrada mostrou-se uma técnica alternativa minimamente invasiva, de baixo custo, segura e, ainda, extremamente útil quando não se conta com o auxílio da broncoscopia flexível.

BACKGROUND AND OBJECTIVE: Difficult airway management in thoracic surgeries is a peculiar subject due to the demands of monopulmonary ventilation with double-lumen tubes. Flexible bronchoscopy guidance is extremely important, but it is not always available. The objective of this report was to describe a case of retrograde selective orotracheal intubation in the absence of specific endoscopy equipment for the procedure. CASE REPORT: This is a patient with a history of retosigmoidectomy, admitted for a right thoracotomy for a lung lesion. Preoperative anesthetic evaluation did not reveal any clinical and physical exam particularities. After anesthetic induction and ventilation with face mask, two attempts of orotracheal intubation under direct laryngoscopy were ineffective due to difficult visualization of the vocal folds (Cormack-Lehane grade III). Due to the unavailability of specific material for selective endoscopic intubation it was decided to use the retrograde technique using the double-lumen tube. The patient was extubated in the operating room shortly after the end of the surgery without complications secondary to the alternative technique. CONCLUSIONS: Retrograde selective orotracheal intubation is a minimally invasive technique, low cost, safe, and extremely useful whenever flexible bronchoscopy is not available.

JUSTIFICATIVA Y OBJETIVOS: El manejo de la vía aérea difícil en cirugía torácica es un asunto peculiar, debido a las exigencias de la ventilación monopulmonar con el uso de tubos de doble lumen. El auxilio de la broncoscopia flexible es de enorme importancia, sin embargo no siempre está disponible. El objetivo de este relato, es describir un caso de intubación orotraqueal selectiva retrógrada en la ausencia de un equipo de endoscopia específico para el procedimiento. RELATO DEL CASO: Paciente con historial previo de retosigmoidectomía que fue ingresado para el abordaje quirúrgico de la lesión pulmonar por toracotomía derecha. La evaluación anestésica preoperatoria no revelaba particularidades ni en la historia clínica ni en el examen físico. Después de la inducción anestésica y ventilación con máscara facial, en la laringoscopia derecha dos intentos de intubación orotraqueal no tuvieron el efecto esperado debido a una difícil visualización de las cuerdas vocales (Cormack-Lehane grado III). En función de la indisponibilidad de un material específico para la intubación selectiva endoscópica, se optó por la técnica retrógrada utilizando un tubo de doble lumen. El paciente fue desentubado en quirófano enseguida que terminó la operación y no presentó complicaciones provenientes de la técnica alternativa. CONCLUSIONES: La intubación orotraqueal selectiva retrógrada fue una técnica alternativa mínimamente invasiva de bajo coste, segura e incluso extremadamente útil cuando no se cuenta con la ayuda de la broncoscopia flexible.

RESUMEN

JUSTIFICATIVA E OBJETIVOS: Os ressuscitadores manuais autoinfláveis (RMA) são dispositivos utilizados para ofertar ventilações para pacientes com necessidade ventilatória. Esses dispositivos são compostos por um conjunto de válvulas que trabalham de forma sequencial e alterações em seu funcionamento podem ser prejudicais ao paciente. RELATO DO CASO: Durante a utilização de RMA, observou-se que a válvula permaneceu fixa devido à presença de secreção pulmonar ressecada, o que impossibilitou a ventilação do paciente, mas não a manipulação da unidade compressível. CONCLUSÕES: Essa situação reafirma que o reanimador é um dispositivo que deve ser usado por profissionais treinados, pois, apesar de as alterações de funcionamento serem raras, podem ser potencialmente fatais.

BACKGROUND AND OBJECTIVES: Self-inflating manual resuscitators (SIMR) are devices used to ventilate patients with ventilatory needs. These devices consist of a set of valves that work sequentially, and changes in their function may be harmful to patients. CASE REPORT: During the use of SIMR, it was observed that the valve remained fixed due to the presence of dried pulmonary secretion, which made it impossible to ventilate the patient, but not manipulate the compressible unit. CONCLUSIONS: This situation reaffirms that the resuscitator is a device that should be used by trained professionals because, although changes in functioning are rare, they can be potentially fatal.
