Intermittent pneumatic compression for the treatment of lower extremity arterial disease: a systematic review

This study aimed to identify the role of intermittent pneumatic compression in treating peripheral arterial disease and to investigate the types of treatment programs that are most effective. Data was sourced from English-language articles which were identi ed by a computer search using MEDLINE from 1966 to 2001, followed by extensive bibliography review. Studies were included if they contained pertinent material involving a compression device and arterial ow dynamics in lower limbs. A total of 26 English-language studies were identi ed that met the inclusion criteria. The diverse patient criteria and methods used in the studies provided an opportunity to examine the effectiveness of each, but made it dif cult to compare one study with another. To assist in focusing on overall trends in improvement, patient type and treatment type disparities must be identi ed. In conclusion, it is evident that an intermittent pneumatic compression program appears promising and may be used in patients with severe peripheral arterial disease who are not candidates for revascularization using surgery or percutaneous angioplasty. It is now the goal to establish randomized, prospective, controlled trials to clarify the most bene cial regimen for treating such disease.

“…As aplicações de CPI na perna e na coxa, mas não no pé, aumentaram significantemente o fluxo da veia femoral (Tabela 1). Embora o aumento do fluxo decorrente da aplicação do pé não tenha sido significante, as aplicações de CPI na perna e coxa produziram elevações significantes no fluxo femoral em relação à aplicação no pé, o que é concordante com descrições prévias da literatura 16,17 .

ResumoContexto: A profilaxia do tromboembolismo venoso pode ser feita por métodos farmacológicos ou de forma mecânica, com o uso de meias antitrombo e compressão pneumática (CPI). A CPI é um método mecânico de profilaxia que merece melhor atenção da comunidade médica.Objetivo: Avaliar o efeito do uso de compressão pneumática intermitente (CPI) nos pés, pernas e coxas de adultos saudáveis sobre o fluxo sanguíneo nas veias femorais comuns. Métodos:A amostra foi constituída de 10 voluntários (sete mulheres e três homens) adultos (20-40 anos), sem antecedente de tromboembolismo venoso. Após repouso (10 min) em decúbito dorsal, o fluxo sanguíneo era medido (três vezes) por ultra-sonografia vascular na veia femoral, a 1 cm acima da junção safeno-femoral, em ambos os membros, sem controle e com CPI no pé, perna e na coxa. A compressão (130 mmHg no pé e 45 mmHg na perna e na coxa) foi aplicada em ciclos de 11 segundos de compressão e 20-60 segundos de esvaziamento. As aferições de fluxo foram realizadas no pico de fluxo do ciclo de compressão. Os valores foram comparados por análise de variância (teste de Tukey), com p < 0,05 indicando diferença estatisticamente significante.Resultado: A utilização de CPI nos membros inferiores, esquerdo e direito, promoveu elevações percentuais relativas no fluxo venoso femoral de 37,6 e 70,8% (pés), 143,9 e 164,7% (pernas) e 132,6 e 128,9% (coxas), respectivamente. As variações foram estatisticamente significantes para as aplicações nas pernas e coxas. Conclusão:A CPI melhora o fluxo sanguíneo quando aplicada na perna ou na coxa.Palavras-chave: Dispositivo de compressão pneumática intermitente, trombose venosa, ultra-sonografia, veia femoral. AbstractBackground: Prophylaxis of venous thromboembolism, a very common post-surgical complication, can be made pharmacologically or via mechanical methods, such as the use of anti-thrombosis socks and intermittent pneumatic compression (IPC). IPC is a mechanical method of prophylaxis that deserves the attention of the medical community.

“…[11][12][13] Other studies have focused on changes in hemodynamic variables after the application of IPC. [14][15][16][17][18][19] Few studies have however investigated the real-time changes in blood flow in the vein during pneumatic compression. 18,20,21 This is likely because of the nonavailability of appropriate tools and methods for real-time measurement of blood flow.…”

Introduction: Intermittent pneumatic compression (IPC) is now a widely used therapy for the prophylaxis of deep vein thrombosis and pulmonary embolism. In general, the IPC sequence is composed of sequential compression and simultaneous deflation. Typically, veins are considered to be squeezed and emptied during the compression phase and to be refilled during the deflation phase. However, because the stop or sudden increase in blood flow can be dangerous, a further investigation is needed with respect to the blood flow. Materials and Methods: We demonstrated a new compression protocol based on the investigation results of venous blood flow during IPC. This new compression protocol involves successive compression without the deflation phase; thus, the expelled blood volume flow during a given period can be maximized. To investigate the blood flow during IPC, sonography movie clips and in-laboratory developed blood flow analysis software was used. Results: The increases in the peak volume flow during IPC were 49% (+24%) and 25% (+29%) with the conventional protocol and the new protocol, respectively, whereas the total volume flow (TVF) was not significantly changed (À1.0% and À13.0%, respectively). With the new protocol, the peak velocity (PV) was 49% lower than that with the conventional protocol. Thus, the new protocol has an effect of maintaining TVF without resulting in a sudden large increase or decrease in PV. Conclusion: The new suggested protocol might improve safety because it can maintain the stability of blood flow by reducing the risk of blood stasis and a rapid change in blood flow.
