Cambios en Mecánica Respiratoria en Usuarios Pediátricos en Ventilación Mecánica Post Cirugía de Cardiopatía Congénita Sometidos a Kinesiología Respiratoria versus Succión Endotraqueal. Revisión Estructurada / Changes in Respiratory Mechanics in Pediatric Users on Mechanical Ventilation Post Congenital Heart Disease Surgery Undergoing Respiratory Kinesiology versus Endotracheal Suction. Structured Review

Introducción. Las cardiopatías congénitas (CC) en Chile corresponden a la segunda causa de muerte en menores de 1 año, requiriendo cirugías paliativas y/o correctivas el 65% de estas. En el post operatorio frecuentemente se utiliza ventilación mecánica invasiva (VM) y succión endotraqueal (SET) para remover secreciones. Sin embargo, la kinesiología respiratoria (KTR) ha mostrado mejoras significativas en la distensibilidad toracopulmonar (Cest) y resistencia de vía aérea (Rva) en otros grupos de usuarios pediátricos y adultos en VM. Objetivo. Comparar los cambios en la Cest y Rva en usuarios pediátricos en VM post cirugía de cardiopatía congénita (CCC) sometidos a KTR versus SET exclusiva. Métodos. Revisión sistemática de estudios publicados en bases de datos PUBMED, PeDro, Scielo y Google Scholar que comparan el uso de KTR ó SET sobre los cambios en mecánica ventilatoria en usuarios pediátricos en VM post cirugía de cardiopatía congénita, limitados a inglés, español y portugués, excluyendo a sujetos con traqueostomía o con oxigenación por membrana extracorpórea. Se utilizó guía PRISMA para la selección de artículos. Se revisaron 397 artículos y se seleccionó 1 artículo extra de los artículos sugeridos. Se eliminó 1 artículo por duplicidad. Por títulos y resúmenes se seleccionaron 2 artículos, los cuales al leer el texto completo fueron retirados debido a que la población no correspondía a cardiópatas. Resultados. El final de artículos seleccionados fue de 0 artículos, debido a lo cual se removió el operador Booleano "NOT", y se removió la población de cardiopatías. De este modo quedaron 2 artículos seleccionados para la revisión cualitativa final donde se compara KTR versus SET, y KTR en kinesiólogos especialistas y no especialistas, mostrando ambos aumento en la Cest y disminución de la Rva a favor de la KTR, hasta los 30 minutos post intervención. Conclusiones. No se encontraron artículos que demuestren cambios en Cest y Rva con el uso de KTR + SET versus SET exclusiva, en usuarios pediátricos ventilados posterior a CCC. Con la remoción de filtros seleccionamos 2 artículos que demuestran aumento de Cest y disminución de Rva en sujetos pediátricos en VM, uno comparando con SET, y por grupos de especialistas y no especialistas en respiratorio. Se sugieren estudios primarios para evaluar los efectos de esta intervención en esta población.

Introduction. Congenital heart diseases (CHD) are the second general cause for children death under 1 year. In Chile, approximately 65% CHD need surgery, could was palliative or corrective. In the postoperative period, invasive mechanical ventilation (MV) is frequently used as a life support method, but it is associated with complications. Tracheal suction (SET) is regularly used to remove secretions; however, respiratory chest physiotherapy (KTR) has shown significant improvements in thoraco-pulmonary compliance and airway resistance in other groups of pediatrics and adult's users in MV. Objetive. to compare changes in thoraco-pulmonary compliance and airway resistance in pediatric subjects under mechanical ventilation after congenital heart disease surgery comparing chest physiotherapy and exclusive tracheal suction. Methods. systematic review of studies published in PUBMED, PeDro, Scielo and Google Scholar databases who compares KTR or SET use on changes in ventilatory mechanics in pediatric users under MV after congenital heart disease surgery, limited to English, Spanish and Portuguese languages, excluding user with tracheostomy or extracorporeal membrane of oxygenation. It was use the PRISMA guide to articles selection. A search was carried out, with a total of 397 articles reviewed (English: PubMed = 3, PeDro = 8, Scholar = 383; Spanish: Scholar = 3, Scielo = 0; and Portuguese: Scielo = 0). One extra article was selected from the suggested articles, and 1 article was eliminated due to duplication. By titles and abstracts, 2 articles were selected, but the population did not correspond to heart disease. Results. the final selected articles were 0 articles. By this reason, it were removed: Boolean operator "NOT", and congenital heart disease population. Thus, 2 articles were selected for the final qualitative review where it was compares KTR versus SET, and KTR by specialist and non-specialist. Both articles shown improvement in compliance and resistance until 30 minutes post intervention. The CC population was in a 40 to 60% range in both studies. Conclusions. it was no found articles that demonstrate changes in compliance and resistance in the airway with the use of KTR + SET versus exclusive SET in pediatric users after CCC connected to MV. After filter remotion, we found 2 studies shown improves in increase compliance and reduce resistance in pediatric user in MV, ones comparing with SET, and the other one comparing between specialists in respiratory pediatric physiotherapy and not specialists. It suggests to made primary clinical studies about this intervention in CC population.

Fisioterapia respiratoria en sujetos adultos cursando internación por neumonía adquirida en la comunidad. Revisión bibliográfica / Respiratory physiotherapy in adult subjects hospitalized for community-acquired pneumonia. Literature review

Introducción: La neumonía adquirida en la comunidad (NAC) es una infección respiratoria en la cual es frecuente observar la indicación de fisioterapia respiratoria (FR). Sin embargo, en la actualidad las recomendaciones respecto a su uso en NAC son controvertidas, no existiendo evidencia que respalde su uso y permita conocer su real alcance. Objetivos: Revisar la evidencia respecto al impacto de la FR en pacientes adultos que cursan internación por NAC. Resultados: 5 estudios cumplieron los criterios de inclusión de esta revisión. Las maniobras de FR incluyeron ejercicios respiratorios, drenaje postural, percusión, vibración, espirometría incentivada, resistencia espiratoria, asistencia torácica durante movimientos respiratorios, tos dirigida y presión positiva intermitente. En los estudios incluidos la FR no disminuyó la mortalidad ni mejoró los valores espirométricos en los pacientes con NAC, así como tampoco los días hasta la curación ni la estadía hospitalaria. Respecto a los costos, el uso de FR en pacientes con NAC presentó un incremento significativo de los mismos. Conclusión: No hay evidencia que respalde el uso de manera rutinaria de FR en los pacientes adultos con NAC. Consideramos que se requieren de futuras investigaciones que permitan conocer el impacto de la FR en pacientes adultos con NAC, así como establecer consensos respecto a su indicación, selección de maniobras, estandarización de técnicas, tiempos y dosificación.

Introduction: Community-acquired pneumonia (CAP) is a respiratory infection in which the indication for respiratory physiotherapy (RF) is frequently observed. However, currently the recommendations regarding its use in CAP are controversial, and there is no evidence to support its use and allow us to know its real scope. Objectives: To review the evidence regarding the impact of RF in adult patients who are hospitalized for CAP. Results: 5 studies met the inclusion criteria of this review. RF maneuvers included breathing exercises, postural drainage, percussion, vibration, incentive spirometry, expiratory resistance, chest support during respiratory movements, directed cough, and intermittent positive pressure. In the included studies, RF did not reduce mortality or improve spirometric values in patients with CAP, nor did it improve days to cure or hospital stay. Regarding costs, the use of RF in patients with CAP presented a significant increase in costs. Conclusion: There is no evidence to support the routine use of RF in adult patients with CAP. We believe that future research is required to determine the impact of RF in adult patients with CAP, as well as to establish consensus regarding its indication, selection of maneuvers, standardization of techniques, times, and dosage.

Safety, tolerability and efficacy of LEGA-Kid® mechanical percussion device versus conventional chest physiotherapy in children: a randomised, single-blind controlled study

INTRODUCTION@#Chest physiotherapy (CPT) may benefit children aged below five years who suffer from lower respiratory tract infection (LRTI). However, its effects depend on the technique used. This study aimed to determine whether mechanical CPT using the LEGA-Kid® mechanical percussion device is superior to manual CPT in children with LRTI.@*METHODS@#Children aged five months to five years who were admitted and referred for CPT from January to April 2017 were randomised to either manual CPT or mechanical CPT with LEGA-Kid. Outcomes measured before intervention and two hours after intervention were respiratory rate (RR), oxygen saturation and modified Respiratory Distress Assessment Instrument (mRDAI) score.@*RESULTS@#All 30 enrolled patients showed significant reduction in post-intervention RR and mRDAI scores. There was an 8% reduction in RR for the manual CPT group (p = 0.002) and a 16.5% reduction in the mechanical CPT group (p = 0.0001), with a significantly greater reduction in the latter (p = 0.024). mRDAI scores decreased by 2.96 in the manual group (p = 0.0001) and 3.62 in the mechanical group (p = 0.002), with no significant difference between the groups. There was no significant improvement in oxygen saturation, and no adverse events were observed after CPT.@*CONCLUSION@#Children receiving both manual and mechanical CPT showed improvements in respiratory distress symptoms, with no adverse effects. A combined strategy of nebulised hypertonic saline followed by CPT for LRTI removes airway secretions and results in improvements in moderately severe respiratory distress. The LEGA-Kid mechanical CPT method is superior to manual CPT in reducing the RR.

Kinesiología respiratoria en niños con disquinesia ciliar primaria / Respiratory phisioterapy in children with primary ciliary dyskinesia

Primary ciliary dyskinesia is a rare autosomal recessive disease with compromised mucociliary drainage. Among the most commonly recommended non-pharmacological therapeutic strategies are secretion drainage techniques. However, the evidence for the use and effectiveness of these techniques is low, and they are generally based on extrapolated evidence of cystic fibrosis. This article reviews the recommendations and available evidence of chest physiotherapy, mainly manual and instrumental techniques of bronchial drainage and physical exercise in children with primary ciliary dyskinesia.

La disquinesia ciliar primaria es una enfermedad autosómica recesiva rara con compromiso del drenaje mucociliar. Entre las estrategias terapéuticas no farmacológicas más comúnmente recomendadas se encuentra las técnicas de drenaje de secreciones. Sin embargo, la evidencia del uso y efectividad de estas técnicas es reducida y generalmente se basan en evidencia extrapolada de la fibrosis quística. Este artículo revisa las recomendaciones y la evidencia disponible de la kinesiología respiratoria, principalmente las técnicas manuales e instrumentales de drenaje bronquial y el ejercicio físico en niños con disquinesia ciliar primaria.

A preventive effect of early and comprehensive pulmonary rehabilitation on pneumonia associated with inva-sive mechanical ventilation / 中华物理医学与康复杂志

Objective To observe any effect of pulmonary rehabilitation in preventing ventilator-associated pneumonia (VAP) among patients receiving invasive mechanical ventilation (MV). Methods A total of 117 a-dults who had be receiving mechanical ventilation for at least 48 hours were randomly divided into an observation group and a control group. Both groups were given routine drug treatment and nursing, but the observation group al-so received comprehensive and individualized pulmonary rehabilitation interventions including airway clearance, respiration training, electrical stimulation of the sacral nerve, lung expansion and early mobilization. The main indi-cators were the incidence of VAP, mortality, MV duration, ICU stay time, and total hospital stay. Results At the end of the treatment the average clinical pulmonary infection score, the acute physiology and chronic health e-valuation Ⅱ score, SpO2 level and oxygenation index of the observation group were all significantly better than those of the control group. The incidence of VAP within one month after leaving the ICU was 47. 5％ in the observation group and the mortality rate was 44.1％, both significantly lower than in the control group. The average MV dura-tion, total hospitalization time and the ICU stay of the observation group were also significantly shorter than those of the control group. Conclusion Early and comprehensive pulmonary rehabilitation can prevent VAP and shorten the length of hospital stays, ICU stays and time on a mechanical ventilator, improving patients' survival chances and prognoses.

Effect of chest physiotherapy in patients undergoing mechanical ventilation: a prospective randomized controlled trial / 中华危重病急救医学

Objective To investigate the effect of chest physiotherapy (CPT) on patients undergoing mechanical ventilation (MV).Methods A prospective randomized controlled trial (RCT) was conducted. Sixty-eight adult patients undergoing invasive MV over 48 hours admitted to intensive care unit (ICU) of Affiliated Hospital of Zunyi Medical College from December 2014 to October 2016 were enrolled, and they were divided into CPT group (n = 37) and control group (n = 31) by random number table. The patients in control group received routine physical therapy; while those in the CPT group received comprehensive CPT including manual lung inflation, vibration expectoration and early functional exercise etc. on the basis of the treatment in control group. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and oxygenation index (PaO2/FiO2) before and after the treatment in both two groups were observed as well as the respiratory function and vital signs before and after CPT. The laboratory indicators after treatment, incidence of complications, duration of MV and the length of ICU stay in the two groups were recorded.Results The incidence of ventilator associated pneumonia (VAP) in the CPT group was significantly lower than that of control group (5.4% vs. 25.8%,P < 0.05), the patients in control group also had atelectasis, deep vein thrombosis and other complications, while no such complications were found in the CPT group. The duration of MV (hours: 77.4±41.0 vs. 133.9±117.2) and the length of ICU stay (hours: 134.4±71.4 vs. 207.4±177.7) in CPT group were significantly shorter than those of the control group (bothP < 0.05). There was no significant difference in APACHE Ⅱ score and PaO2/FiO2 before treatment between the two groups. After treatment for 2 days, the APACHE Ⅱ score in both groups was gradually decreased, and that in CPT group was more significantly, it was significantly lower than that of control group after treatment for 4 days (8.6±3.9 vs. 12.5±5.3,P < 0.05). The PaO2/FiO2 in the two groups was gradually increased after treatment. PaO2/FiO2 in CPT group was significantly increased at 3 days after treatment as compared with that before treatment [mmHg (1 mmHg = 0.133 kPa): 278.1±79.0 vs. 224.2±98.9], while PaO2/FiO2 in the control group did not appear significantly increased until after 4-day treatment (mmHg: 302.3±93.1 vs. 232.3±116.7, both P < 0.05). There was no significant difference in vital signs andrespiratory function parameters including tidal volume (VT), respiratory rate (RR), peak airway pressure (Ppeak) and mean airway pressure (Pmean) before and after treatment in CPT group excepting pulse oxygen saturation (SpO2) was significantly higher than that before treatment (0.985±0.016 vs. 0.978±0.018,P < 0.05), indicating that CPT treatment did not cause fluctuations in respiratory function and vital signs. Blood lactate in CPT group was significantly lower than that of control group (mmol/L: 1.10±0.79 vs. 1.32±1.09, P < 0.05), indicating that CPT treatment, especially early functional exercise, could improve the oxygen supply and limb circulation.Conclusion CPT treatment has some effect on prevention of VAP and other complications in patients undergoing MV, which could shorten the duration of MV and the length of ICU stay, and promote the recovery of patients.

Comparative Study of Two Different Approaches for Managing of Mechanically Ventilated Extremely Preterm Newborns.

Aim: To compare between the effects of routine suctioning and positioning to that of chest physiotherapy on mechanically ventilated newborns. Study Design: Prospective, randomized controlled study. Place and Duration of Study: AL-jahra Hospital, Ministry of Health, Kuwait between January 2012 and April 2013. Methodology: Sixty extremely preterm neonates with respiratory distress syndrome were enrolled in the study. They were mechanically ventilated. Their ages ranged from 4-6 days. They were divided into two equal groups (control and study). The control group received medical treatment, routine suctioning and positioning while the study group received the same medical treatment given to the control group in addition to the selected chest physical therapy program. Arterial blood gases (PaO2, PaCO2, pH) and vital signs (HR, RR, SAP, DAP) were measured. Cranial ultrasound and chest x-ray were done to diagnose any cerebral injuries or rib fractures. All measurements were recorded at baseline measurement, 2 days and 7 days post inclusion in the study. Results: Significant improvement was recorded in arterial blood gases (PaO2, PaCO2, pH) and vital signs (HR, RR, SAP, DAP) for the study group after 2 and 7 days (P< 0.05). In addition to significant differences were observed between both groups in (PaO2, PaCO2, pH, HR, RR, SAP, DAP) in favor of the study one (P< 0.05). No adverse effects regarding to the incidence of rib fractures or cerebral injury were recorded in the study group. Conclusion: Chest physiotherapy is an excellent supplement to the line of treatment of extremely preterm neonates who are mechanically ventilated with respiratory distress syndrome.

Unusually large sized bronchial cast/mucus plug after extubation leading to whole lung collapse-consolidation: a rare case report.

A critically ill patient of enteric encephalopathy with tetanus was hospitalized in a tertiary care ICU and intubated, put on ventilator. Patient had a whole lung collapse-consolidation developed just after extubation and noticed on physical examination and roentgenogram. After extensive chest physiotherapy a long and thick bronchial cast was removed and chest improved markedly thereafter.

Effect of multimodality chest physiotherapy on the rate of recovery and prevention of complications in patients with mechanical ventilation: A prospective study in medical and surgical intensive care units.

Background: Mechanically ventilated patients have an increased risk of complications leading to ventilation weaning more difficult resulting in excessive morbidity and mortality. Chest physiotherapy plays an important role in management of ventilated patients. However, these techniques have been studied on patients as a single entity or with combination of two techniques. The present study was designed to evaluate the effect of multimodality chest physiotherapy on the rate of recovery and prevention of complications in adult ventilated patients. Materials and Methods: Out of 173 patients who were randomly allocated to two groups, 86 patients received MH and suctioning in control group and 87 patients were treated with multimodality chest physiotherapy in the study group twice daily till they were extubated. All patients were followed up for the global outcomes and complications during mechanical ventilation. Results: There were significant improvements in terms of rate of recovery in study group compared to the control group (P = 0.000). Complication rates were higher with 61.6% in the control group as compared to 26.4% in the study group. Duration of hospitalization was longer in the study group (16 ± 9.40 days) as compared to the control group (12.8 ± 6.12 days). Successful weaning from mechanical ventilation was noted in 58 patients in the study group and 24 patients in the control group which was statistically significant. Conclusions: Multi-modality chest physiotherapy protocol has shown to prevent ventilator-associated pneumonia and enhance the clinical outcome in ventilated patients and may be recommended as a treatment option in ICU. It has also shown to enhance the weaning process and proved to be safe.

Fisioterapia respiratória em neonatologia: importância e cuidados / Chest physiotherapy in neonatology: importance and management

Objetivo: Avaliar a importância da fisioterapia respiratória nos cuidados intensivos neonatais, por meio dos trabalhos já publicados na literatura. Métodos: Fontes de dados pesquisadas: Medline, Cochrane Library, LILACS, SciELO. As palavras-chave utilizadas foram neonatos, fisioterapia respiratória, remoção de secreções, hipoxemia e bradicardia. Resultados: A atuação da fisioterapia respiratória foi avaliada entre os cuidados intensivos neonatais, bem como os efeitos da aplicação de suas técnicas. Tem sido aceito que a fisioterapia ajuda na prevenção de complicações respiratórias (diminuição da ventilação e/ou perfusão, obstrução das vias aéreas e aumento do trabalho respiratório) porém, devido à existência de trabalhos com diferentes metodologias e realizados em décadas diferentes, torna-se difícil fazer uma comparação dos seus resultados e, dessa forma, apresentar evidências sobre os efeitos da aplicação das técnicas fisioterapêuticas. Conclusões: A fisioterapia respiratória parece ter um papel importante nos cuidados intensivos neonatais, mas devido à escassez de trabalhos na área se torna difícil a comprovação de seus benefícios.

Combination of chest physiotherapy and intermittent non-invasive mechanical ventilation for chronic obstructive pulmonary disease patients with respiratory failure / 中南大学学报(医学版)

Objective To determine the effect of combination of chest physiotherapy (CPT) and intermittent non-invasive ventilation for chronic obstructive pulmonary disease (COPD) patients with respiratory failure. Methods Ninety COPD patients with intermittent bi-level positive airway pressure (BiPAP) ventilation were randomly divided into 2 groups : control group (n=45) received BiPAP treatment after conventional anti-infection, phlegm treatment and support treatment; CPT group (n=45) received CPT before BiPAP treatment. Clinical symptoms, chest signs, chest X-ray, time of BiPAP therapy, PaO2, and PaCO2 after the treatment were evaluated. Results Compared with with the control group, patients in the CPT group significantly improved in clinical symptoms, chest signs, chest X-ray absorption as well as shorter BiPAP therapy time, PaO2 increase and PaCO2 decrease(P<0.05). Conclusion For COPD patients who need intermittent non-invasive BiPAP ventilation, receiving CPT can effectively improve the therapeutic effect. CPT and intermittent non in-vasive BiPAP ventilation cooperate in the treatment of COPD patients with respirstory failure.

Atelectasias em pediatria: mecanismos, diagnóstico e tratamento: [revisão] / Atelectasis: mechanisms, diagnosis and treatment in the pediatric patient: [review]

OBJETIVO: Realizar uma revisão da literatura sobre os mecanismos, diagnóstico e tratamento das atelectasias pulmonares em pediatria. MÉTODOS:Efetuou-se uma pesquisa nos bancos de dados eletrônicos Medline e Scielo com os critérios de inclusão: artigos publicados entre os anos de 1960 e 2007, que abordassem a etiologia, fisiopatologia, conseqüências funcionais, avaliação, prevenção, tratamento e complicações das atelectasias pulmonares em pediatria. Palavras-chave: atelectasis, children, pediatrics, mucus plugs, chest physiotherapy; atelectasias, criança, pediatria, fisioterapia respiratória, secreção brônquica. Utilizou-se o escore de Sackett DL, 1989 para a classificação do nível de evidência dos artigos encontrados. RESULTADOS:Foram analisados 45 artigos sobre atelectasias pulmonares, sendo 17 artigos em pediatria. Dos artigos com pacientes pediátricos, 13 estudos com série de casos clínicos, três artigos de revisão da literatura e um relato de caso, demonstrando que poucos artigos abordando atelectasias em pediatria foram publicados no período da pesquisa e que o nível de evidência dos artigos existentes são D e E. CONCLUSÃO: Poucos estudos clínicos foram realizados atualmente para identificar o tratamento mais eficaz para a resolução das atelectasias em pediatria. Embora a prática clínica tenha evoluído no tratamento das mesmas, com o aperfeiçoamento das técnicas de broncoscopia e da fisioterapia respiratória existe a necessidade da realização de estudos clínicos randomizados nesta área.

OBJECTIVE: To review the literature about mechanisms, diagnosis and treatment of atelectasis in the pediatric patient. METHODS: An electronic data search was carried out in Medline and Scielo using the following inclusion criteria for articles published between 1960 and 2007 about: atelectasis etiology, physiopathology, functional consequences, evaluation, prevention, treatment and complications, in pediatrics. The used key words were atelectasis, children, pediatrics, mucus plugs, chest physiotherapy; RESULTS: 45 pulmonary atelectasis articles were analyzed, 17 of them in pediatrics. Of the pediatric, 13 were case series, 3 literature reviews and one a case report. This demonstrates that there were few articles on atelectasis during the reviewed period and that these articles were at the D and E evidence level. CONCLUSION: No clinical trials were performed to identify s the most efficient treatment for atelectasis in the pediatric patient. Although clinical practice for treatment of atelectasis has evolved, mostly due to improvement of bronchoscopy and chest physiotherapy techniques, there is still a need to perform randomized clinical trials to address treatment of atelectasis in the pediatric patient.

Breathing pattern, thoracoabdominal motion and muscular activity during three breathing exercises

The objective of the present study was to evaluate breathing pattern, thoracoabdominal motion and muscular activity during three breathing exercises: diaphragmatic breathing (DB), flow-oriented (Triflo II) incentive spirometry and volume-oriented (Voldyne) incentive spirometry. Seventeen healthy subjects (12 females, 5 males) aged 23 ± 5 years (mean ± SD) were studied. Calibrated respiratory inductive plethysmography was used to measure the following variables during rest (baseline) and breathing exercises: tidal volume (Vt), respiratory frequency (f), rib cage contribution to Vt (RC/Vt), inspiratory duty cycle (Ti/Ttot), and phase angle (PhAng). Sternocleidomastoid muscle activity was assessed by surface electromyography. Statistical analysis was performed by ANOVA and Tukey or Friedman and Wilcoxon tests, with the level of significance set at P < 0.05. Comparisons between baseline and breathing exercise periods showed a significant increase of Vt and PhAng during all exercises, a significant decrease of f during DB and Voldyne, a significant increase of Ti/Ttot during Voldyne, and no significant difference in RC/Vt. Comparisons among exercises revealed higher f and sternocleidomastoid activity during Triflo II (P < 0.05) with respect to DB and Voldyne, without a significant difference in Vt, Ti/Ttot, PhAng, or RC/Vt. Exercises changed the breathing pattern and increased PhAng, a variable of thoracoabdominal asynchrony, compared to baseline. The only difference between DB and Voldyne was a significant increase of Ti/Ttot compared to baseline. Triflo II was associated with higher f values and electromyographic activity of the sternocleidomastoid. In conclusion, DB and Voldyne showed similar results while Triflo II showed disadvantages compared to the other breathing exercises.

Comportamento da mecânica pulmonar após a aplicação de protocolo de fisioterapia respiratória e aspiração traqueal em pacientes com ventilação mecânica invasiva / Behavior of the lung mechanics after the application of protocol of chest physiotherapy and aspiration tracheal in patients with invasive mechanical ventilation

JUSTIFICATIVA E OBJETIVOS: A fisioterapia respiratória (FR) em pacientes submetidos a suporte ventilatório invasivo, atua diretamente no sistema ventilatório podendo alterar a mecânica pulmonar através da complacência pulmonar dinâmica (Cdyn) e da resistência do sistema respiratório (Rsr). Porém, as alterações descritas após a realização de FR permanecem controversas. O objetivo deste estudo foi avaliar as alterações da mecânica pulmonar em pacientes em ventilação mecânica invasiva (VMI). MÉTODO: Foi realizado estudo prospectivo e aleatório, controlado do tipo cruzado, incluindo pacientes com mais de 48 horas em VMI. Os protocolos de fisioterapia respiratória (PF) e de aspiração traqueal isolada (PA) foram aleatorizados para a ordem de aplicação, com intervalo de 24 horas entre eles. Dados da mecânica pulmonar e das variáveis cardiorrespiratórias foram coletados antes da aplicação do protocolo, imediatamente após; 30 minutos e 120 minutos após a aplicação dos protocolos. RESULTADOS: Doze pacientes completaram o estudo. A pneumonia foi a causa mais comum de insuficiência respiratória (IRpA). Não houve diferença estatisticamente significativa entre os grupos em relação à Cdyn, volume de ar corrente (VAC) e volume-minuto (VM). A Rsr diminuiu de forma significativa imediatamente após (de 10,4 ± 3 cmH2O/L/seg para 8,9 ± 2 cmH2O/L/seg; p < 0,02), 30 minutos após (de 10,4 ± 3 cmH2O/L/seg para 9 ± 2 cmH2O/L/seg; p < 0,01) e 120 min após (de 10,4 ± 3 cmH2O/L/seg para 9 ± 2 cmH2O/L/seg; p < 0,03) a aplicação do protocolo de fisioterapia respiratória. Quando comparado com o protocolo de aspiração traqueal isolada foi significativamente menor nos momentos 30 (9 ± 2 cmH2O/L/seg versus 10,2 ± 2 cmH2O/L/seg; p < 0,04) e 120 minutos (9 ± 2 cmH2O/L/segundo versus 10,4 ± 3 cmH2O/L/seg; p < 0,04). CONCLUSÕES: O protocolo de fisioterapia respiratória foi eficaz na diminuição da Rsr quando comparado com o protocolo de aspiração. Essa diminuição manteve-se...

BACKGROUND AND OBJECTIVES: The chest physiotherapy (CP) in patients submitted to invasive support ventilation acts directly in the breathing system, and it could alter the lung mechanics through the dynamic lung compliance (DynC) and resistance of the breathing system (Rbs). However the alterations after the accomplishment of CP are still controversy. The objective of this study was to evaluate the alterations of the lung mechanics in patients in invasive mechanical ventilation (IMV). METHODS: It was a prospective, randomized, and controlled and crossover study, with patient with more than 48 hours in IMV. The protocol of chest physiotherapy and isolated tracheal aspiration they were randomized for the application order with a window of 24 hours among them. Data of lung mechanics and its varied cardiorespiratory were collected moments before the protocol, immediately after the application of the protocol, 30 minutes and 120 minutes after the application of the protocols. RESULTS: Twelve patients completed the study. Pneumonia was the mean cause respiratory failure (RF). There was not statistical difference among the groups in relation to Cdyn, volume tidal (Vt) and volume minute (Ve). Rbs decreased in a significant way immediately after (of 10.4 ± 3 cmH2O/L/seg for 8.9 ± 2 cmH2O/L/seg; p < 0.02), 30 minutes after (of 10.4 ± 3 cmH2O/L/seg for 9 ± 2 cmH2O/L/seg; p < 0.01) and 120 minutes after (of 10.4 ± 3 cmH2O/L/seg for 9 ± 2 cmH2O/L/seg; p < 0.03) application the protocol of chest physiotherapy. When compared with the protocol of isolated tracheal aspiration it was significantly smaller in the 30 (9 ± 2 cmH2O/L/seg versus10.2 ± 2 cmH2O/L/seg; p < 0.04) and 120 minutes (9 ± 2 cmH2O/L/seg versus 10.4 ± 3 cmH2O/L/seg; p < 0.04). CONCLUSIONS: The protocol of chest physiotherapy was effective in the decrease of Rsr when compared with the aspiration protocol. That decrease was maintained for two hours after its application, what did not happen...

The Effect of Chest Physiotherapy on the Amount of Tracheal Secretion and PaO2 / 기본간호학회지

The purpose of this research was to find out the effect of chest physiotherapy on the amount of tracheal secretion and PaO2. After changing position of the neurosurgical patients who had tracheostomy cannula, experimental treatments were applied as bellows, manual chest percussion on group I, chest percussion and manual chest vibration on group II, chest percussion and mechanical chest vibration on group III were done. After these trials, we have analyzed the efficacy of each procedures comparing the group differences in the quantity of tracheal secretion and PaO2. Target samples were sixty patients aged between 20 to 60 who have tracheostomy state and decreased consciousness status that were admitted in NICU of a university hospital from June 1 to August 31, 1999. They assigned randomly into three experimental groups. To compare the effect of each interventions, tracheal secretion quantity was measured and PaO2 was analyzed via arterial blood gas analyzer. The data were analyzed by ANCOVA of 5% significance level using SPSS P/C program. The results were as bellows. 1) The first hypothesis " There is a difference in the quantity of the secretion among Group I, Group II and Group III" was accepted.(F=29.27, p=0.00) 2) The second hypothesis "There is a difference in PaO2 among Group I, Group II and Group III" was rejected.(F=1.71,p=0.19) From this study results, positional change and manual chest vibration including chest percussion were the most effective treatment to get maximum amount of tracheal secretion and it was confirmed that mechanical chest vibration also made much better effect than sole chest percussion method. Therefore, we concluded that the mechanical or manual chest vibration with chest percussion is more effective respiratory care method than the sole chest percussion.
