Semiautomatic intermittent pneumatic compression device applied to deep vein thrombosis in major orthopedic surgery

Abstract

ObjectiveTo investigate the effect of additional semiautomatic intermittent pneumatic compression device (IPCD) in the prevention of deep vein thrombosis (DVT) of lower extremity in these patients undergoing major orthopedic surgery, when compared with the conventional graduated compression stockings alone.MethodsThe data of 112 patients undergoing major orthopedic surgery were retrospectively analyzed. 51 patients who ever received IPCD and graduated compression stockings during major orthopedic surgery were taken as the experimental group, and 61 patients who only received the conventional graduated compression stockings during surgery were taken as the observation group. The Doppler sonography was utilized to detect the presence of DVT and pulmonary embolism pre- and postoperatively. Besides, the mean and peak velocity of blood flow in femoral vein were recorded before and after surgery. And then, the comparisons between the two groups were made, respectively.ResultsWhen compared with the conventional graduated compression stockings alone, the intraoperative application of IPCD and stockings contributed the significant reduction of DVT (3.92%, 2/51 versus 9.84%, 6/61, X2 = 5.632, P = 0.034). In terms of the mean and peak velocity of blood flow in femoral vein, the postoperative difference was higher in the observation group than those in the control group (149.56 ± 26.35 versus 130.15 ± 22.56 mm/s, P < 0.05). With respect to perioperative blood loss, the difference between the two groups was statistically significant (800.5 ± 320.7 versus 950.1 ± 305.9 ml, P = 0.031).ConclusionsIntraoperative application of IPCD could promote blood circulation of lower limbs, and significantly decrease the incidence of potentially fatal DVT in patients undergoing major orthopedic surgery, when compared with the conventional graduated compression stockings.

“…The literature, however, does not seem to agree on its effectiveness. 3,4,24,25 The ACCP and the AAOS recommend only intermittent pneumatic compression devices (IPCD) for mechanical prophylaxis. 1,2 The ACCP recommends a portable device (which allows walking) for at least 18 hours a day.…”

“…A literatura, porém, permanece conflitante em relação à sua eficácia. 3,4,24,25 O ACCP e a AAOS, ao recomendarem a profilaxia mecânica, referem-se exclusivamente aos DCM, 1,2 sendo que o ACCP recomenda o modelo portátil (que permita deambulação concomitante) e com adesão mínima de 18 horas por dia. 1 Este tipo de dispositivo, contudo, é utilizado por apenas 5% dos nossos entrevistados e, destes, apenas 2 o prescrevem por > 18 horas por dia.…”

European guidelines on peri-operative venous thromboembolism prophylaxis: first update.

“…16 In a retrospective study involving 112 patients undergoing orthopaedic surgery, IPC combined with GCS was better than GCS alone in terms of increased blood circulation as measured by Doppler sonography. 17 Again, the majority of studies are based on systematic VTE screening rather than clinical signs of thrombosis, and thus these results should be interpreted with caution.…”

Effects of different intensities of intermittent pneumatic soft-tissue compression on bone defect repair

“…This has led to the introduction of several treatment modalities to enhance healing and expedite recovery [ 1 ]. Intermittent pneumatic compression (IPC) is a special technique that has been mainly used in orthopedic practice to decrease the risk of deep vein thrombosis (DVT) and to reduce post-traumatic and post-operative swelling in various clinical situations [ 2 – 4 ]. Physicians have tried to improve circulation by exerting external pressure on the arms and legs since nineteenth century.…”
