Effect of prophylactic non-invasive mechanical ventilation on functional capacity after heart valve replacement: a clinical trial.

OBJECTIVE: During cardiac surgery, several factors contribute to the development of postoperative pulmonary complications. Non-invasive ventilation is a promising therapeutic tool for improving the functionality of this type of patient. The aim of this study is to evaluate the functional capacity and length of stay of patients in a nosocomial intensive care unit who underwent prophylactic non-invasive ventilation after heart valve replacement. METHOD: The study was a controlled clinical trial, comprising 50 individuals of both sexes who were allocated by randomization into two groups with 25 patients in each group: the control group and experimental group. After surgery, the patients were transferred to the intensive care unit and then participated in standard physical therapy, which was provided to the experimental group after 3 applications of non-invasive ventilation within the first 26 hours after extubation. For non-invasive ventilation, the positive pressure was 10 cm H2O, with a duration of 1 hour. The evaluation was performed on the 7th postoperative day/discharge and included a 6-minute walk test. The intensive care unit and hospitalization times were monitored in both groups. Brazilian Registry of Clinical Trials (REBeC): RBR number 8bxdd3. RESULTS: Analysis of the 6-minute walk test showed that the control group walked an average distance of 264.34±76 meters and the experimental group walked an average distance of 334.07±71 meters (p=0.002). The intensive care unit and hospitalization times did not differ between the groups. CONCLUSION: Non-invasive ventilation as a therapeutic resource was effective toward improving functionality; however, non-invasive ventilation did not influence the intensive care unit or hospitalization times of the studied cardiac patients.

Cardiac rehabilitation programme after transcatheter aortic valve implantation versus surgical aortic valve replacement: Systematic review and meta-analysis.

Background Aortic stenosis is a valvular heart disease characterised by fixed obstruction of the left ventricular outflow. It can be managed by surgical aortic valve replacement (sAVR) or transcatheter aortic valve implantation (TAVI). This review aimed to describe the evidence supporting a cardiac rehabilitation programme on functional capacity and quality of life in aortic stenosis patients after sAVR or TAVI. Methods The search was conducted on multiple databases from January to March 2016. All studies were eligible that evaluated the effects of a post-interventional cardiac rehabilitation programme in aortic stenosis patients. The methodological quality was assessed using the PEDro scale. Meta-analysis was performed separately by procedure and between procedures. The walked distance during the six-minute walk test (6MWD) and Barthel index were evaluated. The analysis was conducted in Review Manager. Results Five studies were included (292 TAVI and 570 sAVR patients). The meta-analysis showed that a cardiac rehabilitation programme was associated with a significant improvement in 6MWD (0.69 (0.47, 0.91); P < 0.001) and Barthel index (0.80 (0.29, 1.30); P = 0.002) after TAVI and 6MWD (0.79 (0.43, 1.15); P < 0.001) and Barthel index (0.93 (0.67, 1.18); P < 0.001) after sAVR. In addition, the meta-analysis showed that the cardiac rehabilitation programme promoted a similar gain in 6MWD (4.28% (-12.73, 21.29); P = 0.62) and Barthel index (-1.52 points (-4.81, 1.76); P = 0.36) after sAVR or TAVI. Conclusions The cardiac rehabilitation programme improved the functional capacity and quality of life in aortic stenosis patients. Patients who underwent TAVI benefitted with a cardiac rehabilitation programme similar to sAVR patients.

Analysis of steps adapted protocol in cardiac rehabilitation in the hospital phase.

OBJECTIVE: To analyze a cardiac rehabilitation adapted protocol in physical therapy during the postoperative hospital phase of cardiac surgery in a service of high complexity, in aspects regarded to complications and mortality prevalence and hospitalization days. METHODS: This is an observational cross-sectional, retrospective and analytical study performed by investigating 99 patients who underwent cardiac surgery for coronary artery bypass graft, heart valve replacement or a combination of both. Step program adapted for rehabilitation after cardiac surgery was analyzed under the command of the physiotherapy professional team. RESULTS: In average, a patient stays for two days in the Intensive Care Unit and three to four days in the hospital room, totalizing six days of hospitalization. Fatalities occurred in a higher percentage during hospitalization (5.1%) and up to two years period (8.6%) when compared to 30 days after hospital discharge (1.1%). Among the postoperative complications, the hemodynamic (63.4%) and respiratory (42.6%) were the most prevalent. 36-42% of complications occurred between the immediate postoperative period and the second postoperative day. The hospital discharge started from the fifth postoperative day. We can observe that in each following day, the patients are evolving in achieving the Steps, where Step 3 was the most used during the rehabilitation phase I. CONCLUSION: This evolution program by steps can to guide the physical rehabilitation at the hospital in patients after cardiac surgery.

The use of the virtual reality as intervention tool in the postoperative of cardiac surgery.

INTRODUCTION: Cardiac surgery has been the intervention of choice in many cases of cardiovascular diseases. Susceptibility to postoperative complications, cardiac rehabilitation is indicated. Therapeutic resources, such as virtual reality has been helping the rehabilitational process. The aim of the study was to evaluate the use of virtual reality in the functional rehabilitation of patients in the postoperative period. METHODS: Patients were randomized into two groups, Virtual Reality (VRG, n = 30) and Control (CG, n = 30). The response to treatment was assessed through the functional independence measure (FIM), by the 6-minute walk test (6MWT) and the Nottingham Health Profile (NHP). Evaluations were performed preoperatively and postoperatively. RESULTS: On the first day after surgery, patients in both groups showed decreased functional performance. However, the VRG showed lower reduction (45.712.3) when compared to CG (35.0612.09, P<0.05) in first postoperative day, and no significant difference in performance on discharge day (P>0.05). In evaluating the NHP field, we observed a significant decrease in pain score at third assessment (P<0.05). These patients also had a higher energy level in the first evaluation (P<0.05). There were no differences with statistical significance for emotional reactions, physical ability, and social interaction. The length of stay was significantly shorter in patients of VRG (9.410.5 days vs. 12.2 1 0.9 days, P<0.05), which also had a higher 6MWD (319.9119.3 meters vs. 263.5115.4 meters, P<0.02). CONCLUSION: Adjunctive treatment with virtual reality demonstrated benefits, with better functional performance in patients undergoing cardiac surgery.

INTRODUÇÃO: A cirurgia cardíaca tem sido a intervenção de escolha em muitos casos de doenças cardiovasculares. Pela susceptibilidade a complicações pós-operatórias, a reabilitação cardíaca é indicada. Recursos terapêuticos, como a realidade virtual, tem favorecido o processo reabilitacional. O objetivo do estudo foi avaliar o uso da realidade virtual na reabilitação funcional de pacientes pós-cirurgia cardíaca. MÉTODOS: Os pacientes foram randomizados em dois grupos, Realidade Virtual (GRV, n=30) e Grupo Controle (GC, n=30). A resposta ao tratamento foi avaliada por meio do Questionário de Medida de Independência Funcional (MIF), Teste de caminhada de 6 minutos e do Perfil de Saúde de Nottingham (PSN). Os questionários foram aplicados no pré e pós-operatório. RESULTADOS: No primeiro dia de pós-operatório, os pacientes de ambos os grupos demonstraram diminuição do desempenho funcional. No entanto, essa perda foi menor no GRV (45,712,3) em relação ao GC (35,0612,09, P<0,05), sem diferença significativa no momento da alta hospitalar (P>0,05). Na avaliação do PSN, foi observada menor intensidade da dor no terceiro momento de avaliação no GRV (P<0,05). Esses pacientes também apresentaram maior nível de energia na primeira avaliação (P<0,05). Não foram encontradas diferenças com significância estatística para reações emocionais, habilidade física e interação social. O tempo de internação foi significativamente menor nos pacientes do GRV (P<0,05), que também apresentaram maior distância percorrida no TC6 (319,9119,3 metros vs. 263,5115,4 metros, P<0,02). CONCLUSÃO: O tratamento com a realidade virtual foi eficaz em proporcionar melhor desempenho funcional pós-operatório.
