“…This number represents a cumulative prevalence and incidence in patients with ongoing thromboprophylaxis. Hong et al prospectively screened 90 ICU patients without prophylaxis and repeated admission ultrasound 5–7 days after admission and 11.1% of patients developed DVT [30]. Sud et al [13] compared ultrasound screening versus clinically suspected DVT case finding in medical-surgical ICU patients and found 85 proximal DVT´s per 1000 patients.…”

BackgroundData on prevalence rates of venous thromboembolism (VTE) in different patient populations are scarce. Most studies on this topic focus on older patients or patients with malignancies, immobilization or thrombophilia. Less is known about the VTE risk profile of non-surgical patients presenting with a variety of medical diseases of differing severity. Aim of the present study was to investigate VTE prevalence in a pospective cohort study of ambulatory medical intensive care unit patients within 24 h after acute admission.MethodsProspective cohort study of 102 consecutive patients after acute admission to medical intensive care unit. Ultrasound compression sonography, APACHE-II-Scoring and laboratory examination was performed within 24 hours after admission.Possible determinants of a high risk of VTE were examined. In all patients with a confirmed diagnosis of DVT or suspicion of PE thoracic computer tomography (CT) was performed.ResultsVTE was found in 7.8% out of 102 of patients, mean APACHE-II-Score was 14 (mortality risk of about 15%). Thrombus location was femoropopliteal in 5 patients, iliacal in 2 and peroneal in 1 patient. Five VTE patients had concomitant PE (62.5% of VTE, 4.9% of all patients). No predictors of prevalent VTE were identified from univariable regression analysis although relative risk was high in patients with a history of smoking (RR 3.40), immobility (RR 2.50), and elevated D-Dimer levels (RR 3.49).ConclusionsPrevalent VTE and concomitant PE were frequent in acutely admitted ICU patients.

“…The available literature describes the prevalence, incidence and risk factors associated with the development of DVT among patients admitted to medical and surgical intensive care units and following trauma, neurosurgery, or spinal cord injury. [1][2][3][4][5][6][7] An estimated 10-30% of medical and surgical intensive care unit patients are known to develop DVT within the first week of admission. However, there is limited to no data about the DVT risk profile of patients admitted to a neuro-intensive care unit (NICU).…”

JHN JOURNAL 38 JHN JOURNAL Background: Deep venous thrombosis (DVT) of the lower extremities is a common cause of morbidity and mortality among neurologically injured patients. The data on incidence and prevalence rates of DVT among high risk neurologic populations is scarce. The available literature focuses largely on patients admitted to a medical or surgical intensive care unit with very limited information on patients in neuro-intensive care units (NICU). The aim of the present study is to assess the incidence and prevalence of deep vein thrombosis among patients admitted with acute neurologic injury. Methods:We conducted a retrospective review of ultrasound records of 2,644 patients admitted to NICU, stroke or INICU at a university hospital over a 13-month period. We included all patients who underwent routine lower extremity ultrasound on admission and weekly. Data was abstracted and analyzed to assess the prevalence of DVT in this period. We excluded patients presenting with superficial vein thrombosis, hematoma and chronic venous scarring.Results: Among the 2,644 patients studied, 161 were diagnosed with DVT. The overall prevalence of DVT was 6.1%. Of the 161 cases of DVT; 87 (54%) were diagnosed with DVT at the time of admission. In our sample, the rate of DVT present on admission was 3.3%. There were 74 cases of hospital-acquired DVT, yielding an incidence of 2.8%. Patients with DVT at the time of admission were largely Caucasian males with mean age 72 and mean SAPS II score of 34.2, ranging between 13 and 71.Conclusions: Patients admitted to a neuro ICU are at high risk for having DVT present on admission and for acquiring DVT during their hospitalization. Further research is needed to understand the risk profile of patients with acute neurological injury. Asymptomatic screening of high risk patients on admission to a neurologic ICU, stroke unit, or intermediate care unit will identify a significant number of cases of DVT present of admission that might otherwise be misidentified as hospital acquired cases.

“…If the wall of the lower-extremity vein is damaged, blood flow congestion and/or excessive coagulation may overcome the tendency to inhibit thrombus formation, and deep vein thrombosis (DVT) may occur in the lower extremity2 ) . DVT is a major public health challenge with an incidence rate of 0.3% in the general elderly population3 ) . DVT prevention is crucial and cost effective for critically ill patients.…”

The Effects of Squat Exercises in Postures for Toilet Use on Blood Flow Velocity of the Leg Vein

2014

[Purpose] The purpose of this study was to identify the effects of squat exercises performed in toilet-using postures on the blood flow velocity of the lower extremities for the prevention of deep vein thrombosis. [Subjects] The subjects were 28 students who were attending B University in Cheonan. They were divided into a group of 14 subjects of sitting toilet users and a group of 14 subjects of squat toilet users. [Methods] The subjects performed squat exercises in different toilet-using postures and we investigated the changes in blood flow velocity. [Results] The variations in blood flow velocities before and after the exercises showed significant differences in both groups but the differences between the two groups were not significant. [Conclusion] Based on the results of this study, we consider squat exercises are effective at improving the variation in lower-extremity blood flow velocity when using a toilet.

Risk factors and incidence of deep vein thrombosis in lower extremities among critically ill patients

Abstract: The results of this study could allow ICU nurses to recognise the DVT incidence in critically ill patients. This result could lead to more active prevention and monitoring of DVT by ICU nurses, especially for high-risk patients, such as older or obese patients.
