To 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.
The 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.
When 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, X = 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).
Intraoperative 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.
研究在骨科大手术后，与单独使用常规分级加压弹力袜相比，额外使用半自动间歇充气加压装置（IPC 装置）对预防下肢深静脉血栓（DVT）的效果。
回顾性分析 112 例骨科大手术患者的资料。51 例骨科大手术中使用 IPC 装置和分级加压弹力袜的患者作为实验组，61 例仅在手术中使用常规分级加压弹力袜的患者作为观察组。术前和术后均采用多普勒超声检查有无 DVT 和肺栓塞。记录术前和术后股静脉血流的平均速度和峰值速度，然后分别进行两组比较。
与单独使用常规分级加压弹力袜相比，IPC 装置和弹力袜术中应用显著降低了 DVT 的发生率（3.92%，2/51 与 9.84%，6/61，X=5.632，P=0.034）。股静脉血流平均速度和峰值速度方面，观察组术后差值高于对照组（149.56±26.35 与 130.15±22.56mm/s，P<0.05）。两组围手术期出血量差异有统计学意义（800.5±320.7 与 950.1±305.9ml，P=0.031）。
与常规分级加压弹力袜相比，IPC 装置术中应用可促进下肢血液循环，显著降低骨科大手术患者致命性 DVT 的发生率。
