The effect of positive end-expiratory pressure level on peak expiratory flow during manual hyperinflation

Including positive end-expiratory pressure (PEEP) in the manual resuscitation bag (MRB) may render manual hyperinflation (MHI) ineffective as a secretion maneuver technique in mechanically ventilated patients. In this study we aimed to determine the effect of increased PEEP or decreased compliance on peak expiratory flow rate (PEF) during MHI. A blinded, randomized study was performed on a lung simulator by 10 physiotherapists experienced in MHI and intensive care practice. PEEP levels of 0-15 cm H2O, compliance levels of 0.05 and 0.02 L/cm H2O, and MRB type were randomized. The Mapleson-C MRB generated significantly higher PEF (P < 0.01, d = 2.72) when compared with the Laerdal MRB for all levels of PEEP. In normal compliance (0.05 L/cm H2O) there was a significant decrease in PEF (P < 0.01, d = 1.45) for a PEEP more than 10 cm H2O in the Mapleson-C circuit. The Laerdal MRB at PEEP levels of more than 10 cm H2O did not generate a PEF that is theoretically capable of producing two-phase gas-liquid flow and, consequently, mobilizing pulmonary secretions. If MHI is indicated as a result of mucous plugging, the Mapleson-C MRB may be the most effective method of secretion mobilization.

Efeitos ventilatórios da fisioterapia respiratória com e sem hiperinsuflação manual em recém-nascidos pré-termos sob ventilação mecânica

Atualmente, os recém-nascidos nascem cada vez mais prematuros, dependendo de cuidados intensivos neonatais. Nesse sentido, a fisioterapia respiratória tem adquirido um espaço cada vez maior, e juntamente com uma equipe multidisciplinar presta assistência a esses recém-nascidos prematuros. Entre as diversas técnicas utilizadas pelos fisioterapeutas, a hiperinsuflação manual tem tido papel fundamental na remoção de secreções brônquicas. Objetivo: Avaliar os efeitos hemodinâmicos e respiratórios da fisioterapia respiratória, com ou sem a manobra de hiperinsuflação manual em recém-nascidos prematuros. Método: Participaram deste estudo 9 recém-nascidos prematuros com idade gestacional média 32,364 semanas, nascidos no Hospital Universitário Alzira Velano, no período de abril a novembro de 2015. Os recém-nascidos foram aleatoriamente divididos em 2 grupos: B, onde se realizou a fisioterapia respiratória associada a hiperinsuflação manual; e o grupo A, em que receberam somente a fisioterapia respiratória. Foram avaliados os seguintes parâmetros: frequência cardíaca, frequência respiratória e saturação de oxigênio, 5 minutos antes da realização dos procedimentos, 1 minuto e trinta minutos após os procedimentos. Resultados: Em relação à frequência cardíaca, a fisioterapia respiratória (FR) não demonstrou diferenças estatisticamente significativas nos momentos avaliados A1 (147,80), A2 (158,40) e A3 (151,20), bem como na fisioterapia respiratória associada à hiperinsuflação manual (FR+HM) nos mesmos momentos A1 (130,75), A2 (138,50) e A3 (137,25). Na frequência respiratória também não se verificou diferenças estatisticamente significativas nos momentos A1 (53,80), A2 (50,60) e A3 (46,60) com FR e nos mesmos momentos A1 (57,00), A2 (52,25) e A3 (59,50) com FR+HM. Na saturação de oxigênio, a FR nos momentos avaliados A1 (94,80), A2 (95,60) e A3 (95,60) não demonstrou alterações estatisticamente significativas como visto também na FR+HM nos mesmos momentos avaliados A1 (94,25), A2 (92,50) e A3 (95,00).Conclusão: Verificou-se com os resultados que as frequências cardíacas e respiratórias e a saturação de oxigênio não apresentaram diferenças estatisticamente significativas pré e pós realização da fisioterapia respiratória convencional ou associada à hiperinsuflação manual.

Efeitos da higienização brônquica nas variáveis cardiorrespiratórias de pacientes em ventilação mecânica

INTRODUCTION: During mechanical ventilation (MV), the airways may accumulate secretions. Patients are submitted to Respiratory Therapy (RT) and tracheal aspiration when in MV, alone or associated, to eliminate these secretions. OBJECTIVE: The objective was to compare the effects of different protocols of bronchial hygiene in blood pressure, heart rate, oxygen saturation and respiratory rate of patients undergoing MV. MATERIALS AND METHODS: We conducted a prospective, randomized, controlled crossover, with intentional non-probabilistic sample in the Medical School Hospital of Marília. We included patients in invasive MV who were submitted to three different bronchial hygiene protocols: PP - physiotherapy protocol (manual chest compression and manual hyperinflation); AP - aspiration protocol; and PP + AP. Respiratory rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation and heart rate were evaluated in three moments: before (M1), immediately after (M2) and 30 minutes after (M3) for each protocol. The differences among protocols and times were assessed using ANOVA and post hoc Student Newman-Keus (p < 0.05). RESULTS: We studied eighteen 71.2 ± 13.9 year-old patients with 15.1 ± 17.7 days of MV. There were no differences among protocols. There was a significant decreasing in SBP (p = 0.0261) and DBP (p = 0.0119) from M2 to M3 in the aspiration protocol. CONCLUSION: There was a decrease of blood pressure on MV patients after 30 minutes of aspiration and no change in the other variables, and there was no difference among protocols.

Training and development for transitional employment in mature-aged manual workers

The purpose of the current article was to explore perceptions of transitional employment and training and development amongst blue collar workers employed in technical, trade, operations or physical and labour-intensive occupations within the local government system.

Promoting Adult Resilience (PAR): Group Leaders Manual

RAP-A was developed to meet the need for a universal resilience building program for teenagers which could be readily implemented in a school setting. A universal program targets all teenagers in a particular grade as opposed to those at higher risk for depression (indicated or selective approaches) or a treatment group. It is easier to recruit and engage adolescents in a universal approach where students do not face the risk of stigmatisation by being singled out for intervention. The Resourceful Adolescent Program (RAP: Shochet, Holland & Whitefield, 1997) was developed to meet this need.

Metacognitive narrative psychotherapy for people diagnosed with schizophrenia : an outline of a principle-based treatment manual

Schizophrenia is often characterised by diminished self-experience. This article describes the development and principles of a manual for a psychotherapeutic treatment model that aims to enhance self-experience in people diagnosed with schizophrenia. Metacognitive Narrative Psychotherapy draws upon dialogical theory of self and the work of Lysaker and colleagues, in conjunction with narrative principles of therapy as operationalised by Vromans. To date, no manual for a metacognitive narrative approach to the treatment of schizophrenia exists. After a brief description of narrative understandings of schizophrenia, the development of the manual is described. Five general phases of treatment are outlined: (1) developing a therapeutic relationship; (2) eliciting narratives; (3) enhancing metacognitive capacity; (4) enriching narratives, and; (5) living enriched narratives. Proscribed practices are also described. Examples of therapeutic interventions and dialogue are provided to further explain the application of interventions in-session. The manual has been piloted in a study investigating the effectiveness of Metacognitive Narrative Psychotherapy in the treatment of people diagnosed with schizophrenia spectrum disorders.
