1、神经手术病人深静脉血栓的预防Prevention of Deep Vein Thrombosis in potential Neurosurgical PatientsA Randomized Trial Comparing Graduated Compression Stockings Alone or Graduated Compression Stockings Plus Intermittent pneumatic Compression With Control Alexander G.

2、; Denise Julian, MS; Judith Johnson, RN In a randomized trial of neurosurgical patients, groups wearing graduated compression stockings alone (group 1) or graduated compression stockings plus Intermittent pneumatic compression (IPC) (group 2) were compared with an untreated control group In the prev
3、ention of deep vein throm-b0sis (DVT). In both active treatment groups, the graduated compression stockings were continued for 14 days or until hospital discharge, if earlier. In group 2, IPC was continued for seven days. All patients underwent DVT surveillance with iodine 125-labeled fibrlnogen leg
4、 scanning and Impedance plethysmogrephy. Venography was carried out if either test became abnormal. Deep vein thrombosis occurred in seven (8.8%) of 80 patients in group 1, in seven (9.0%) of 78 patients in group 2, and in 16 (19.8%) of 81 patients in the control group. The observed differences amon
5、g these rates are statistically significant. The results of this study indicate that graduated compression stockings alone or in combination with IPC are effective methods of preventing DVT In neurosurgical patients. (Arch Intern Med 1989;149:679-681 )Deep vein thrombosis (DVT) and pulmonary embolis
6、m (PE) are common causes of morbidity and mortality in neurosurgical patients. The incidence of DVT detected by iodine I 125-labeled fibrinogen leg scanning and impedance plethysmography (IPG) in neurosurgical populations has been reported to be 20% to 30%. Fatal PE occurs in approximately 1% of neu
7、rosurgical patients. Several methods for preventing DVT following neurosurgery are available, but the most attractive are the physical methods, including graduated compression stock-rugs or intermittent pneumatic compression (IPC) devices Anticoagulant prophylaxis with low-dose heparin is effective
8、in general surgical patients, but the use of anticoagulants in neurosurgical patients is problematic because of the potential for serious bleeding. Antiplatelet drugs have not been universally effective for thrombosis prophylaxis and are not widely used. In a recent study in neurosurgical patients,
9、suloctidil, a new antiplatelet drug, was found to be ineffective in preventing DVT. Intermittent pneumatic compression is an effective method of prophylaxis in both general surgical patients and neurosurgical patients. Despite its demonstrated efficacy, IPC is not widely used for the prevention of D
10、VT in neurosurgical patients, possibly because of the perception that it is inconvenient to both patients and nursing staff.Accepted for publication June 7, 1988.

Arch Intern Med-Vo1149, March 1989 Graduated compression stockings, which are

We have therefore performed a randomized clinical trial for the prevention of DVT in neurosurgical patients comparing graduated compression stockings alone or graduated compression stockings plus IPC with a control group receiving standard phy
