Aspiração endotraqueal de adultos intubados: evidências para boas práticas / Endotracheal suctioning of the adults intubated: evidence for best practice

Introdução: A aspiração endotraqueal é o procedimento invasivo mais realizado em indivíduos intubados em unidades de terapia intensiva. Contudo, existem poucos estudos nacionais de boa qualidade metodológica sobre o assunto, não havendo no Brasil consenso da literatura e/ou padronização da técnica. Objetivos: Estabelecer recomendações baseadas em evidências científicas sobre a aspiração endotraqueal em adultos intubados. Métodos: Revisão sistemática de estudos secundários: diretrizes, guidelines e revisões sistemáticas em inglês e português, pesquisada nas bases de dados PubMed, Cochrane, Cochrane Review, Cochrane Library, Scielo Org, Scielo Brasil, PEDro, Clinical Evidence e Evidence Based Medicine. Resultados: Foram incluídos cinco artigos com classificação entre C e D pelo R-Amstar. Conclusão: A aspiração endotraqueal deve ser realizada em adultos intubados por pessoal qualificado, assepticamente, sempre que necessária. Não deve exceder 15 segundos por aspiração e nem ser realizada rotineiramente, e sim, na presença de secreções ­ grau de recomendação A. A sonda de aspiração deve ter um diâmetro menor que 50% do tubo endotraqueal e a hiperoxigenação com fração inspirada de oxigênio a 100% no ventilador deve ser utilizada ­ grau de recomendação A. A pressão de sucção não deve exceder 150 mmHg negativos ­ grau de recomendação B. É recomendada a aspiração subglótica, especialmente naqueles indivíduos com mais de 72 horas de ventilação mecânica invasiva ­ grau de recomendação A. (AU)

Introduction: Endotracheal aspiration is the most accomplished invasive procedure in intubated individuals in intensive care units. However, there are few national studies of good methodological quality on the subject, and there is no consensus in the literature and / or standardization of the technique. Aims: To establish recommendations based on scientific evidence on endotracheal aspiration in intubated adults. Methods: Systematic review of secondary studies: guidelines, guidelines and systematic reviews in English and Portuguese, searched in the databases PubMed, Cochrane, Cochrane Review, Cochrane Library, Scielo Org, Scielo Brazil, PEDro, Clinical Evidence and Evidence Based Medicine. Results: Five articles with classification between C and D by R-Amstar were included. Conclusion: Endotracheal aspiration should be performed in adults intubated by qualified personnel, aseptically, whenever necessary. It should not exceed 15 seconds per aspiration and should not be performed routinely, but in the presence of secretions - degree of recommendation A. The aspiration probe should have a diameter of less than 50% of the endotracheal tube and hyperoxigenation with inspired fraction of oxygen at 100% in the ventilator should be used - degree of recommendation A. The suction pressure should not exceed 150 mmHg negative - degree of recommendation B. Subglottic aspiration is recommended, especially in those individuals with more than 72 hours of invasive mechanical ventilation - degree of Recommendation A. (AU)

Mid-and long-term result of endovascular therapy for lower extremity deep venous thrombosis / 中华普通外科杂志

Objective To evaluate the mid-term and long-term result of mechanical aspiration thrombectomy or combined with balloon thrombectomy,venoplasty and catheter-directed thrombolysis therapy for lower extremity deep venous thrombosis.Methods Clinical data of 1 068 admitted patients were analysed retrospectively from January 2000 to June 2010.Among these patients,271 cases were treated by thrombectomy only,537 cases received thrombectomy with arterial catheter-directed thrombolysis,260 cases were treated by thrombectomy with dorsalis pedis vein thrombolysis,492 patients with stenosis or obstruction of iliac vein underwent venoplasty treatment.Results After 36 month follow-up edema,pigmentation and chronic ulcers were 10.26％,7.28％,1.55％ respectively.The patency without reflux,patency with reflux,residual thrombus,occlusion rate of the iliofemoral vein were 84.25％,8.95％,4.3％,2.5％ respectively; The patency,residual thrombus and occlusion rate of popliteal vein were 93.32％,5.49％,1.19％.Iliac vein stent patency rate was 92.28％.Conclusions Endovascular treatment for lower extremity deep venous thrombosis was a reasonable therapy with a satisfactory mid-term and long-term result,protecting venous valve function and reducing the morbidity of post-thrombotic syndrome.

Initial Experience Using the 5MAX(TM) ACE Reperfusion Catheter in Intra-arterial Therapy for Acute Ischemic Stroke

OBJECTIVES: The 5MAX ACE is a new large bore aspiration catheter available for vessel recanalization for treatment of acute ischemic stroke (AIS). We report our initial experience with its use. METHODS: A retrospective analysis of patients undergoing intra-arterial therapy for AIS using the 5MAX ACE reperfusion catheter at our institution was performed. Patient demographics, clinical characteristics and procedural data were obtained from chart review. Successful recanlization was defined as achievement of Thrombolysis in Cerebral Infarction score (TICI) 2b-3 and time to recanalization was defined as time from groin puncture to achievement of at least TICI 2b recanalization. RESULTS: The 5MAX ACE was used in 15 patients from July-October 2013. Direct aspiration was used as the primary technique in 10/15 (67%) patients. Out of these, aspiration alone was sufficient for recanalization in 3 (20%) patients. In the remaining 7 (47%) patients, additional devices were used. In 5/15 (33%) patients, combined aspiration/stentriever thrombectomy using Solitaire(TM) (3/5 patients) and Penumbra 3D Separator(TM) (2/5 patients) were used as the primary technique. Successful recanlization (TICI 2b-3) was achieved in 11/15 (73%) patients. Average time from groin puncture to successful recanalization was 46 +/- 30 minutes (range 14-98 minutes). There were no procedural complications. CONCLUSION: The 5MAX ACE is a useful recanalization tool, either by direct aspiration or combined stentriever/aspiration. It may be most advantageous with large clots in the internal carotid artery. The potential for effective and faster recanalization using this device alone or in combination may be a good topic for future study.
