Early discharge for patients with benign pleural effusions using a Wayne catheter (pigtail) chest drain - analysis of safety, complications, and quality of life.

OBJECTIVE: to assess safety, efficacy and quality of life in patients with benign pleural effusions undergong pleural drainage with Wayne pleural catheter (DW) in an outpatient setting. METHOD: this is a prospective study, in which 47 patients were evaluated between July 2017 and October 2018. Patients with non-malignant pleural effusions underwent pleural drainage with clinical evolution compatible with outpatient care were included. Patients who underwent drainage due to other conditions and patients were excluded. RESULTS: after catheter placement, the mean length of hospital stay was 3.14 (± 3.85) days, and 21 patients (44.68%) were discharged within 24 hours. The mean time with the catheter was 12.63 (± 7.37) days. The analysis of the pleural fluid was transudate in 87.3% of cases and exudate in 12.3%. The causes of pleural effusion were heart failure (72.3%), renal failure (19.1%), liver failure (6.3%) and pneumonia (8.5%). The quality of life, analyzed according to the parameters of the questionnaire SF 36, showed low average values when compared to other studies. Analyzing each descriptor, the average was greater only in the limitation related to physical aspects. In the other descriptors, the results were similar, but smaller. CONCLUSION: the outpatient use of pleural catheters of the Wayne type (pigtail) proved to be feasible, safe and with a low associated infection rate. This is a viable option for selected patients.

RESUMO Objetivo: avaliar a segurança, a eficácia, as complicações e a qualidade de vida da alta precoce e acompanhamento ambulatorial de pacientes com derrames pleurais benignos submetidos à drenagem pleural com dreno de Wayne (DW). Método: estudo prospectivo, em que foram avaliados 47 pacientes entre julho de 2017 e outubro de 2018. Foram incluídos os pacientes com derrames pleurais não malignos, submetidos a drenagem pleural com evolução clínica compatível com o cuidado ambulatorial. Foram excluídos os pacientes submetidos a drenagem por outras afecções. Resultados: após a drenagem, a média do tempo de internação dos pacientes foi de 3,14 (±3,85) dias, sendo que 21 pacientes (44,68%) tiveram alta em até 24 horas após a drenagem. O tempo médio de permanência com o dreno foi de 12,63 (±7,37) dias. A análise do líquido pleural mostrou tratar-se de transudato em 87,3% dos casos e de exsudato em 12,3%. Dentre as causas do derrame pleural, destacaram-se insuficiência cardíaca (72,3%), insuficiência renal (19,1%), hepatopatias (6,3%) e pneumonias (8,5%). A qualidade de vida, analisada segundo os parâmetros do questionário SF 36, teve valores médios baixos, principalmente em relação a outros estudos. Na análise de cada descritor, a média apresentou-se maior somente na limitação por aspectos físicos. Nos demais descritores, os resultados foram semelhantes, mas menores. Conclusão: o uso ambulatorial de cateteres pleurais do tipo Wayne (pigtail) mostrou-se factível, seguro e com baixa taxa de infecções associadas. Trata-se de opção viável para pacientes selecionados.

Comparative study of transepidermal water loss in patients with and without hyperhidrosis by closed-chamber measurer in an air-conditioned environment.

OBJECTIVE: To evaluate the difference in transepidermal water loss in patients diagnosed with hyperhidrosis and healthy subjects, in an air-conditioned environment. METHODS: Twenty patients diagnosed with hyperhidrosis and 20 healthy subjects were subjected to quantitative assessment using a closed-chamber device, in six previously established sites. RESULTS: The measurements showed different transepidermal water loss values for healthy subjects and patients with hyperhidrosis, especially in the hands and feet. In the Control Group, the median for the hands was 46.4g/m2/hour (p25: 36.0; p75: 57.6), while in the Hyperhidrosis Group, the median was 123.5g/m2/hour (p25: 54.3; p75: 161.2) - p<0.001. For the feet, the Control Group had a median of 41.5g/m2/hour (p25: 31.3; p75: 63.5) and the Hyperhidrosis Group, 61.2g/m2/hour (p25: 32.3; p75: 117) - p<0.02. Measurements of the axillas also showed differences. In the Control Group, the median was 14.8g/m2/hour (p25: 11.8; p75: 19.0) and, in the Hyperhidrosis Group, 83.5g/m2/hour (p25: 29.5; p75: 161.7) - p<0.001. CONCLUSION: Measuring transepidermal water loss is sufficient for diagnosis and follow-up of patients with hyperhidrosis.

RESUMO Objetivo Avaliar a diferença entre a perda transepidérmica de água aferida entre pacientes com e sem diagnóstico de hiperidrose, em ambiente climatizado. Métodos Foram selecionados 20 pacientes com diagnóstico de hiperidrose e 20 hígidos, submetidos à aferição de maneira quantitativa, com mensurador de câmara fechada, em seis locais previamente estabelecidos. Resultados As medidas realizadas mostraram valores diferentes de perda transepidérmica de água em pessoas hígidas e naquelas com hiperidrose, principalmente em mãos e pés. No Grupo Controle, a mediana das aferições em mãos foi 46,4g/m2/hora (p25: 36,0; p75: 57,6), enquanto, no Grupo Hiperidrose, obtivemos a mediana de 123,5g/m2/hora (p25: 54,3; p75: 161,2) - p<0,001. Já nos pés, a mediana no Grupo Controle foi 41,5g/m2/hora (p25: 31,3; p75: 63,5) e, no Grupo Hiperidrose, foi 61,2g/m2/hora (p25: 32,3; p75: 117) - p<0,02. As medidas das regiões axilares também mostraram diferença. No Grupo Controle, obtivemos mediana 14,8g/m2/hora (p25: 11,8; p75: 19,0) e, no Hiperidrose, 83,5g/m2/hora (p25: 29,5; p75: 161,7) - p<0,001. Conclusão A mensuração da perda transepidérmica de água é suficiente para diagnóstico e acompanhamento de pacientes com hiperidrose.
