Avaliação da força de preensão palmar e dos volumes pulmonares de pacientes hospitalizados por condições não cirúrgicas Evaluation of handgrip strength and lung volumes inpatients hospitalized for nonsurgical conditions

Patients with CHD are less active if compared with controls and have limited functional capacity, related to muscle weakness and fatigue. The aim of this study was to evaluate the peripheral and respiratory muscle strength of children and adolescents with CHD with systematic review and meta-analysis. The review included observational and randomised control trial studies which evaluated peripheral and respiratory muscle strength in children and adolescents with CHD under 18 years old. The peripheral muscle strength was evaluated through dynamometry and respiratory muscle strength through manovacuometry. In studies that compared patients with CHD and respective control groups, it was possible to perform a meta-analysis. A total of 5634 articles met the criteria of eligibility, 15 were included in the systematic review, and 4 were included in the meta-analysis. Twelve studies assessed peripheral muscle strength with a reduction in patients with CHD. In the meta-analysis, patients with CHD had lower muscle strength than controls (−34.07 nm; 95% CI, −67.46 to −0.68; I2 47%; p for heterogeneity = 0.05), and the meta-analysis of the handgrip muscle strength showed no significant difference between patients with CHD and controls (0.08 nm; 95% CI, −6.39 to 6.55; I2 98%; p for heterogeneity <0.00001). The meta-analysis in the present study  showed lower limb muscle strength in patients with CHD in comparison to controls. In contrast, no difference was found regarding hand grip strength. Also, the review showed lower respiratory muscle strength in patients with CHD, yet no meta-analysis was possible to perform.

Justificativa e objetivo: A DPOC é caracterizada pela limitação progressiva do fluxo aéreo associada a uma resposta inflamatória. O objetivo do estudo foi avaliar a influência e a associação das variáveis respiratórias sobre a capacidade de exercício em portadores de DPOC. Métodos: Estudo transversal avaliou 39 portadores de DPOC para obtenção do volume expiratório forçado no primeiro segundo (VEF1) e a capacidade vital forçada (CVF). A força muscular respiratória (FMR) avaliada em seus componentes de pressão inspiratória máxima (PImax) e pressão expiratória máxima (PEmax). Capacidade de exercício avaliada pelo Teste de Caminhada de Seis Minutos (TC6m) e Incremental Shuttle Walking Test (ISWT). Resultados: O VEF1 (% 39,8±15,3) e CVF (% 60,2±17,1) se encontram reduzidos em relação ao predito classificando-os em estadiamento grau II (21%), III (51%) e IV (28%). A PImax (92,7±14,6 % predito) e PEmax (97,6±19,0 % predito) se encontram dentro dos valores previsto para os sujeitos. Evidenciada correlação moderada entre a distância percorrida no ISWT vs VEF1 (r=0,35; p=0,02) e ISWT vs CVF (r=0,42; p

O não produziu alteração na taxa de depuração. Backgound and Objectives:Positive airway pressure continues (CPAP) produces significant hemodynamic changes that may influence the variability of breathing pattern and heart rate, acting as an additional therapy to prevent atelectasis and to combat hypoxia. The rate of inhaled 99m Technetium-diethylenetriaminepentaacetic acid ( 99m Tc-DTPA), along with changes in the lung epithelium cause an increase in the rate of clearance of this compound. The aim of this study was evaluate the pulmonary clearance rate of 99m Technetium-Diethylenetriaminepentaacetic acid ( 99m Tc-DTPA) through the use of different levels of CPAP. Methods: It was a quasi-experimental study involving 17 healthy individuals with normal lung functional. Tc-DTPA clearance moreover, 10 cmH 2 O did not alter its clearance rate. RESUMO ABSTRACT
