ABSTRACT
Em pacientes que se encontram internados na Unidade de Terapia Intensiva muitas vezes é necessário o uso de ventilação mecânica, para manutenção das vias aéreas superiores. Essa necessidade limita a mobilização e a expectoração das secreções brônquicas, sendo necessário fazer uso de aspiração traqueal. O Objetivo foi avaliar os critérios utilizados para aspiração traqueal em unidades de Terapia Intensiva de hospitais de Araxá-MG. Trata-se de um estudo previamente aprovado pelo CEP-Uniaraxá e pelos hospitais envolvidos na pesquisa, do tipo transversal, descritiva e quali-quantitativo. Foi aplicado um questionário composto por 9 questões discursivas entregues aos profissionais das instituições participantes. Resultados foram avaliados 15 profissionais sendo 40% Técnicos em enfermagem, 27% Enfermeiros 27% Fisioterapeutas e 6% Auxiliares de enfermagem. Quanto a importância da aspiração 41% dos participantes responderam que a desobstrução das vias aéreas pela aspiração traqueal é de extrema importância para o paciente. Concluímos que o procedimento de aspiração traz vários riscos aos pacientes. Requer atenção, cuidado e habilidade, o que nos faz concluir que é necessário um melhor aperfeiçoamento da técnica para um melhor atendimento e manutenção da saúde do paciente(AU)
In patients who are hospitalized in the Intensive Care Unit, it is often necessary to use mechanical ventilation to maintain the upper airways. This necessity limits the mobilization and the expectoration of the bronchial secretions, being necessary to make use of tracheal aspiration. The objective was to evaluate the criteria used for tracheal aspiration in Intensive Care units of hospitals in Araxá-MG. This is a study previously approved by CEP-Uniaraxá and the hospitals involved in the research, of a crosssectional, descriptive and quali-quantitative type. A questionnaire composed of 9 discursive questions was given to the professionals of the participating institutions. Results were evaluated 15 professionals being 40% Nursing technicians, 27% Nurses 27% Physiotherapists and 6% Nursing auxiliaries. Regarding the importance of aspiration, 41% of the participants answered that the airway clearance by tracheal aspiration is extremely important for the patient. We conclude that the aspiration procedure poses several risks to patients. It requires attention, care and skill, which makes us conclude that a better improvement of the technique is required for a better care and maintenance of the patient's health(AU)

Nosocomial pneumonia is a common complication in patients on mechanical ventilation and results in significant mortality. Diagnosis of pneumonia in patients who are intubated and under mechanical ventilation is difficult, even with the aid of clinical, laboratorial, and endoscopic tests. The objective of this study was to compare three methods of tracheal sputum collection in patients with a clinical and radiological diagnosis of pneumonia. Twenty-two patients with a clinical diagnosis of liver disease were enrolled, 18 years of age or older, 13 males and nine females, who had been mechanically ventilated over an intubation period of 5.86 ± 4.62 days. These patients were being treated in intensive care unit (ICU) of the Liver Transplantdepartment. Secretion collection was carried out according to a protocol with three distinct methods: endotracheal aspiration with a closed aspiration system, Bal cath and bronchoalveolar lavage. Of the 22 patients analyzed, 21 (95.4 percent) showed one or more infectious agent when the closed aspiration system was used. With the Bal cathâ collection, 19 patients (86.3 percent) had one or more infectious agents; in the collection by bronchoalveolar lavage, 10 patients (45.4 percent) presented one or more infectious agent. According to the laboratorial analysis, 14 different microorganisms were isolated, the most frequent of which were Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae. We concluded that aspiration with the closed system produced the most effective results in comparison with those of bronchoalveolar lavage and the Bal cathâ, and may be an acceptable method for diagnosing hospital-acquired pneumonia when no fiberoptic technique is available.

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...

BACKGROUND: The aim of this study is to determine the clinical outcomes of early vancomycin administration before identification of methicillin-resistant Staphylococcus aureus (MRSA) in patients with nosocomial pneumonia on a ventilator. METHODS: We retrospectively reviewed patients with nosocomial pneumonia in a 20-bed medical ICU during a period of 2 years and 2 months. This study included 52 inpatients, who were admitted for more than 72 hr and had a new or progressive lung infiltrate plus at least two of the following three criteria for pneumonia: abnormal body temperature (>38oC or 10,000/mm3 or <3,000/mm3), and purulent bronchial secretions. All of the MRSA were identified in tracheal aspirates during mechanical ventilation. RESULTS: A total of 23 patients who received vancomycin prior to identification of MRSA exhibited a 28-day mortality rate of 60%, while 29 patients who received vancomycin after identification of MRSA showed a 28-day mortality rate of 40% (p=0.17). There was no statistically significant difference in severity index and routine laboratory findings between the two groups. CONCLUSIONS: Early vancomycin administration before identification of MRSA does not appear to affect the mortality rate for patients with nosocomial pneumonia.

OBJECTIVE: The purpose of this study is to find the proper feeding posture for the safe liquid meal in the patients with neurogenic dysphagia. METHOD: Fifty patients of neurogenic dysphagia with tracheal aspiration diagnosed with the videofluoroscopic swallowing test (VFST) were evaluated. VFST using 5 cc of barium solution was done for each patient in the sitting and supine position. The results of VFST of supine position were analyzed and compared with those of sitting position for the tracheal aspiration, laryngeal penetration, premature leakage, and laryngeal spillage. RESULTS: The incidence of premature leakage, tracheal aspiration, and laryngeal penetration is significantly decreased in the supine position (56%, 14% and 46%) compared to the sitting position (96%, 100% and 100%) (p<0.001). The incidence of laryngeal penetration referable to the swallowing reflex is significantly decreased in the supine position (0%, 46%, 0%) compared to the sitting position (14%, 96%, 44%) (p<0.001). The incidence of nasal regurgitation is 2% in the sitting position and 30% in the supine position. CONCLUSION: The incidence of tracheal aspiration of liquid diet is significantly decreased in the supine position compared to the sitting position. The supine position would be safer than the sitting position in the feeding of liquid diet.

OBJECTIVE: To assess the incidence of tracheal aspiration in the brain injury patients with laryngeal penetration, and to investigate the relationship between the type of laryngeal penetration and the severity of tracheal aspiration. METHOD: One hundred videofluoroscopic swallowing tests in brain injury patients who showed laryngeal penetration were analyzed retrospectively. Laryngeal penetrations were classified into three groups: anterior, posterior and both. The incidence of the tracheal aspiration among the laryngeal penetration was evaluated. The severity of the tracheal aspiration was analyzed into the three groups: mild, moderate and severe. Each type of the laryngeal penetration were compared with the severity of the tracheal aspiration. RESULTS: Seventy-one patients showed the tracheal aspiration among the 100 patients with laryngeal penetration. The incidence of tracheal aspiration according to the type of the laryngeal penetration was 100% in both, 86.8% in posterior, and 50.9% in anterior type. The more severe tracheal aspiration was associated with the higher proportion of the posterior and both types. CONCLUSION: The incidence of tracheal aspiration in laryngeal penetration was 71%. More severe tracheal aspiration occurred with both & posterior laryngeal penetration than anterior type.
