Abstract
For physical-based compression therapeutic modalities, especially compression stockings (CSs), their pressure performances are necessarily evaluated by the standardized cylinder leg mannequins before biological applications. However, the insufficient pressure supply caused by morphological shape diversities between circular leg mannequins and irregular bio-bodies limits the clinical effectiveness and user compliance of CSs. Therefore, an operable and efficiency approach for optimization bio-design and digital development of CSs with enhanced compression performances needs to be proposed. The present study has adopted three-dimensional (3D) body scanning and reverse engineering technologies for lower limb cross-sectional geometric characterization and morphological classification. The irregularity of biological leg circumferential slices was determined and clustered as four levels relating to individual curvature variations. Sequentially, a new pressure prediction model was constructed through characterized geometric variations for bio-based bodies, then its acceptability was validated with good agreement by wearing trials (mean prediction accuracy was 2.53 ± 0.52 mmHg). Thus, the digital pressure reshaped development guidance was obtained based on the classified irregular levels and established pressure prediction models. Consequently, this study provides a novel reliable optimization bio-design solution for manufacturing of therapeutic compression textiles and facilitates the medical efficacy and precision of compression therapy in practical use.

Healthcare (Basel) 2022; 11:healthcare11010122. [PMID: 36611582 PMCID: PMC9819428 DOI: 10.3390/healthcare11010122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/24/2022] [Accepted: 12/27/2022] [Indexed: 01/03/2023] Open
Abstract
This study aimed to assess the effect of a combined exercise program on lower-extremity alignment and knee pain in patients with genu varum. Forty-seven middle-aged women with knee pain and genu varum were randomly divided into the exercise (EG, n = 24) and control (CG, n = 23) groups. The exercise group underwent a combined exercise program lasting 60 min in one session, three times a week for 12 weeks. Knee-to-knee length (KTKL), hip-knee-ankle angle (HKAA), hip inclination angle (HIA), and medial proximal tibial angle (MPTA) were assessed to evaluate lower-extremity alignment. To evaluate knee pain, the short form-McGill Pain Questionnaire (SF-MPQ) were used. There was a significant difference between the groups, and a decrease of 16% in KTKL (from 6.48 ± 1.26 cm to 5.47 ± 1.21 cm) was shown in EG. Other variables, including HKAA, HIA, and MPTA on the right side, showed significant differences between pre- and post-intervention in EG (p < 0.01, p < 0.01, and p < 0.01, respectively). SF-MPQ score improved with 45% from 18.75 ± 1.64 to 10.33 ± 2.47 after exercise intervention in EG. These results suggest that the combined exercise program, including strength and neuromuscular exercises, is an effective intervention for improving lower-extremity alignment and knee pain in middle-aged women with genu varum.

Abstract
Introduction Traumatic and non-traumatic spinal cord injury bears a high risk for thromboembolism in the first few months after injury. So far, there is no consented guideline regarding diagnostic and prophylactic measures to prevent thromboembolic events in spinal cord injury. Based on a Pubmed research of related original papers and review articles, international guidelines and a survey conducted in German-speaking spinal cord injury centers about best practice prophylactic procedures at each site, a consensus process was initiated, which included spinal cord medicine experts and representatives from medical societies involved in the comprehensive care of spinal cord injury patients. The recommendations comply with the German S3 practice guidelines on prevention of venous thromboembolism. Recommendations Specific clinical or instrument-based screening methods are not recommended in asymptomatic SCI patients. Based on the severity of neurological dysfunction (motor completeness, ambulatory function) low dose low molecular weight heparins are recommended to be administered up to 24 weeks after injury. Besides, mechanical methods (compression stockings, intermittent pneumatic compression) can be applied. In chronic SCI patients admitted to the hospital, thromboembolism prophylactic measures need to be based on the reason for admission and the necessity for immobilization. Conclusions Recommendations for thromboembolism diagnostic and prophylactic measures follow best practice in most spinal cord injury centers. More research evidence needs to be generated to administer more individually tailored risk-adapted prophylactic strategies in the future, which may help to further prevent thromboembolic events without causing major side effects. The present article is a translation of the guideline recently published online (https://www.awmf.org/uploads/tx_szleitlinien/179-015l_S1_Thromboembolieprophylaxe-bei-Querschnittlaehmung_2020-09.pdf).

Abstract
OBJECTIVES To investigate whether the use of graduated compression stockings (GCS) offers any adjuvant benefit when pharmaco-thromboprophylaxis is used for venous thromboembolism prophylaxis in patients undergoing elective surgery. DESIGN Open, multicentre, randomised, controlled, non-inferiority trial. SETTING Seven National Health Service tertiary hospitals in the United Kingdom. PARTICIPANTS 1905 elective surgical inpatients (≥18 years) assessed as being at moderate or high risk of venous thromboembolism were eligible and consented to participate. INTERVENTION Participants were randomly assigned (1:1) to receive low molecular weight heparin (LMWH) pharmaco-thromboprophylaxis alone or LMWH pharmaco-thromboprophylaxis and GCS. OUTCOME MEASURES The primary outcome was imaging confirmed lower limb deep vein thrombosis with or without symptoms, or pulmonary embolism with symptoms within 90 days of surgery. Secondary outcome measures were quality of life, compliance with stockings and LMWH, lower limb complications related to GCS, bleeding complications, adverse reactions to LMWH, and all cause mortality. RESULTS Between May 2016 and January 2019, 1905 participants were randomised. 1858 were included in the intention to treat analysis (17 were identified as ineligible after randomisation and 30 did not undergo surgery). A primary outcome event occurred in 16 of 937 (1.7%) patients in the LMWH alone group compared with 13 of 921 (1.4%) in the LMWH and GCS group. The risk difference between the two groups was 0.30% (95% confidence interval -0.65% to 1.26%). Because the 95% confidence interval did not cross the non-inferiority margin of 3.5% (P<0.001 for non-inferiority), LMWH alone was confirmed to be non-inferior. CONCLUSIONS For patients who have elective surgery and are at moderate or high risk of venous thromboembolism, administration of pharmaco-thromboprophylaxis alone is non-inferior to a combination of pharmaco-thromboprophylaxis and GCS. These findings indicate that GCS might be unnecessary in most patients undergoing elective surgery. TRIAL REGISTRATION ISRCTN13911492.

Abstract
The study focused on assessing the effect of nurse-led deep vein thrombosis prevention training on patients' knowledge and self-care practices. Forty patients participated in this quasi-experimental study. Participants were trained by the guidebook prepared by the researchers before the surgery. Data were collected with Autar Deep Vein Thrombosis Risk Assessment Scale and questionnaires before and after the training. The questionnaires were prepared by the researcher. Data were evaluated with Mann-Whitney U, Wilcoxon, Kruskal-Wallis variance analysis, significance of difference test between two means, and one-way variance analysis tests. The average deep vein thrombosis knowledge score was 0.1 ± 0.5 over 54 before the training, whereas it was 20.2 ± 5.7 after the training, and there was a statistically significant difference in patients' deep vein thrombosis knowledge scores after training period (P = .000). Patients performed an average of 8.8 out of 13 protective self-care practices during the postsurgery period. The majority of the patients were satisfied with the training. The training provided by the nurse contributed to the fact that the patients had knowledge about their own health problems and took responsibility for self-care. We have not been able to increase the awareness we want on some groups such as those older than 52 years. Other studies should be carried out, especially in these groups, with different training methods.

Abstract
The Association of Paediatric Anaesthetists of Great Britain and Ireland (APAGBI) Guidelines Working Group on Thromboprophylaxis in Children has reviewed the literature and where possible provided advice on the care of children in the perioperative period. Areas reviewed include the incidence of perioperative venous thromboembolism (VTE), risk factors, evidence for mechanical and chemical prophylaxis, and complications. Safe practice of regional anesthesia with anticoagulant prophylaxis is detailed. In summary, there are few areas of strong evidence. Routine prophylaxis cannot be recommended for young children. Postpubertal adolescents (approximately 13 years and over) are at a slightly increased risk of VTE and should be assessed for prophylaxis and may warrant intervention if other risk factors are present. However, the incidence of VTE is significantly lower than in the adult population. This special interest review presents a summary and discussion of the key recommendations, a decision-making algorithm and a risk assessment chart.

Abstract
SummaryCompression is performed postoperatively with the intention of minimising side effects, such as bleeding and haematoma in the area of operation, as well as postoperative oedema and pain. Compression stocking manufacturing has incorporated the addition of skin care products into the yarn material in recent years. However, the benefits of these products remain controversial. In addition, the length of the compression stocking is disputed in terms of its effectiveness. This effectiveness was investigated in the present study.Before surgery, 160 patients with indication of surgical removal of varicose veins were randomly divided into four groups with different types of compression stockings in each case. In each group, 40 patients received a knee-length stocking (length A–D), thigh-length stocking (length A–G), knee-length stocking with Aloe vera or thigh-length stocking with AV. At time 0 (before surgery), one week and 8 weeks after surgery, skin moisture was measured as an objective parameter, quality of life was determined using the Freiburger questionnaire of quality of life in veinous disease (FLQA-vs), benefit to patients was evaluated using the patient benefit index (PBI-v) and further subjective parameters were investigated with a free-text questionnaire. After surgery, the extent of haematoma was determined using the point count method.After surgery, at both post-operative times, the FLQA-vs decreased significantly (corresponding to a better quality of life), and the PBI-v increased. In the group with Aloe, pruritus was significantly lower, comfort and skin moisture were increased, and skin condition was significantly improved. The extent of haematoma decreased regardless of the length of the stockings.A benefit of AV as a skin care additive was observed. This finding was objectively confirmed based on the skin moisture. The multifactorial quality of life was not affected by the skin care additive. Thigh-length compression stockings did not provide a measurable benefit.

Abstract
BACKGROUND Deep-vein thrombosis (DVT) can occur in surgical patients. Routine prophylaxis can be pharmacological and/or mechanical [e.g. graduated compression stockings (GCSs)]. GCSs are available in knee length or thigh length. OBJECTIVE To establish the expected value of undertaking additional research addressing the relative effectiveness of thigh-length GCSs versus knee-length GCSs, in addition to pharmacoprophylaxis, for prevention of DVT in surgical patients. DESIGN Systematic review and economic model, including value of information (VOI) analysis. REVIEW METHODS Randomised controlled trials (RCTs) assessing thigh- or knee-length GCSs in surgical patients were eligible for inclusion. The primary outcome was incidence of DVT. DVT complications and GCSs adverse events were assessed. Random-effects meta-analysis was performed. To draw on a wider evidence base, a random-effects network meta-analysis (NMA) was undertaken for the outcome DVT. A review of trials and observational studies of patient adherence was also conducted. A decision-analytic model was developed to assess the cost-effectiveness of thigh- and knee-length GCSs and the VOI. RESULTS Twenty-three RCTs were included in the review of effectiveness. There was substantial variation between trials in terms of the patient characteristics, interventions and methods of outcome assessment. Five trials comparing knee-length with thigh-length GCSs with or without pharmacoprophylaxis were pooled; the summary estimate of effect indicated a non-significant trend favouring thigh-length GCSs [odds ratio (OR) 1.48, 95% confidence interval (CI) 0.80 to 2.73]. Thirteen trials were included in the NMA. In the base-case analysis, thigh-length GCSs with pharmacoprophylaxis were more effective than knee-length GCSs with pharmacoprophylaxis (knee vs. thigh OR 1.76, 95% credible interval 0.82 to 3.53). Overall, thigh-length stockings with pharmacoprophylaxis was the most effective treatment, with a 0.73 probability of being the most effective treatment in a new trial of all the treatments. Patient adherence was generally higher with knee-length GCSs, and patients preferred knee-length GCSs. Thigh-length GCSs were found to be cost-effective in all but the subgroup with the lowest baseline risk, although the absolute differences in costs and effects were relatively small. The expected value of perfect information ranged from £0.2M to £178.0M depending on the scenario and subgroup. The relative effect parameters had the highest expected value of partial perfect information and ranged from £2.0M to £39.4M. The value of further research was most evident in the high-risk subgroups. LIMITATIONS There was substantial variation across the included trials in terms of patient and intervention characteristics. Many of the included trials were old and poorly reported, which reduces the reliability of the results of the review. CONCLUSIONS Given that the results from both the standard meta-analysis and the NMA lacked precision (CIs were wide) owing to the heterogeneous evidence base, a new definitive trial in high-risk patients may be warranted. However, the efficiency of any further research (i.e. whether this represents value for money) is dependent on several factors, including the acquisition price of GCSs, expected compliance with thigh-length GCSs wear, and whether or not uncertainty can be resolved around possible effect modifiers, as well as the feasibility and actual cost of undertaking the proposed research.

Abstract
Patients undergoing surgery are at an increased risk of VTE. Since the early 1990s the prevention of VTE has been dominated by the administration of low-molecular weight heparin during admission. New oral anticoagulants have been extensively researched and have increased in popularity. This chapter reviews why surgical patients are at increased risk of VTE and summaries both the pharmacological and mechanical methods of prophylaxis available.

Abstract
AIMS AND OBJECTIVES To compare the comfort levels of patients regarding the use of three different graduated compression stockings and to analyse the efficacies of the graduated compression stockings in relation to patient comfort and compliance in prevention of postoperative deep vein thrombosis. BACKGROUND Graduated compression stockings are very important with other prophylaxis methods in postoperative deep vein thrombosis prophylaxis. In meta-analyses and systematic review studies, it was reported that knee-length and thigh-length graduated compression stockings had similar efficacies. However, there is no randomised study in literature regarding the patient problems and levels of comfort with the use of graduated compression stockings of different sizes and pressures. DESIGN A randomised clinical trial design. METHODS A total of 219 patients were randomised into three groups (n = 73 in each group). Group I was given low-pressure, knee-length graduated compression stockings, group II was given low-pressure, thigh-length graduated compression stockings and group III was given moderate-pressure, knee-length graduated compression stockings. The level of patients comfort regarding the graduated compression stockings and occurrence of deep vein thrombosis were examined. RESULTS The vast majority of the patients (79·5%) in group III and 52·1% of the patients in group II stated experiencing problems during the use of the graduated compression stockings (p < 0·001). The graduated compression stockings were reported by the patients as being very comfortable in the group I (p < 0·001). No findings of thrombosis were observed in any of the groups. CONCLUSION The low-pressure, knee-length graduated compression stockings are as effective as the other graduated compression stockings of different pressures and sizes in the postoperative deep vein thrombosis prophylaxis, and the patients have fewer problems while using these graduated compression stockings with a high satisfaction. RELEVANCE TO CLINICAL PRACTICE The combined use of pharmacological, mechanical and physical methods and patient education is effective in the prevention of postoperative deep vein thrombosis. The use of low-pressure, knee-length graduated compression stockings in clinical practice may be recommended, as the patients have fewer problems while using these graduated compression stockings with a high satisfaction.

Abstract
BACKGROUND Venous thromboembolism (VTE) represents a significant preventable cause of hospital mortality. VTE assessment and prophylaxis rates are key patient safety and quality of care indicators. The aim of this study was to audit low molecular weight heparin (LMWH) and graduated elasticated compression stockings (GECS) prescriptions compared with the current Clinical Guidelines for Operations. METHODS Complete audit loop in the Role 3 Hospital, Camp Bastion, Afghanistan. A multifaceted intervention programme incorporating physician and nurse education and pre-printed medication charts was introduced to improve VTE assessment and prophylaxis rates. RESULTS Only 111/301 (36.9%) of patients in the pre-intervention cohort had a VTE risk assessment performed; this improved to 142/155 (91.6%, p<0.0001) post-intervention. A total of 57/88 (64.8%) patients prescribed LMWH pre-intervention had a documented assessment of bleeding risk performed; this rose to 65/66 (98.5%, p=0.0003) post-intervention. In pre-intervention, only 63/213 (29.6%) patients had a documented reassessment of VTE and bleeding risk at 24 h; reassessment rates rose to 68.8% (66/96 patients, p<0.0001) post-intervention. Of those patients at risk of VTE without ongoing bleeding risk, 62/96 (64.6%) had LMWH prescribed pre-intervention; this rose to 57/62 (91.9%) post-intervention (p<0.0001). Inappropriate LMWH prescription rates fell from 26/190 (13.7%) to 4/85 (4.7%, p=0.035) post-intervention. In those patients in whom GECS were not contraindicated, prescription rates rose from 23/95 (24.2%) to 42/62 (67.7%, p<0.0001) post-intervention. CONCLUSIONS Inclusion of pre-printed LMWH/GECS prescriptions and risk assessment stickers in the mediction chart significantly improved rates of VTE risk assessment and prophylaxis. These easily reproducible and low-cost interventions could improve patient safety on deployment.

Abstract
Up to half of patients with proximal deep vein thrombosis (DVT) will develop post-thrombotic syndrome (PTS) despite optimal anticoagulant therapy. PTS significantly impacts upon quality of life and has major health-economic implications. This narrative review describes the pathophysiology, risk factors, and diagnosis, prevention and treatment of PTS, to improve our understanding of the disease and guide treatment. Relevant articles were identified through systematic searches of the PubMed, EMBASE and Cochrane databases between 1966 and November 2011. Studies were included for detailed assessment if they met the following criteria: published in English, human study participants, study population aged > 18 years, and lower limb post-thrombotic syndrome. All non-systematic reviews and single patient case reports were excluded. Recurrent thrombosis, thrombus location and obesity are major risk factors, whereas the importance of gender and age remain uncertain. The diagnosis of PTS is based on clinical findings in patients with a known history of DVT. Several clinical scales have been described, with the Villalta Score gaining increasing popularity. Adequate anticoagulation and use of elastic compression stockings (ECS) following DVT can reduce the incidence of PTS. Catheter-directed thrombolysis and mechanical thrombectomy of acute DVT may preserve valvular function. Studies to date of these techniques are encouraging, and have reported improved hemodynamics and a reduced incidence of PTS. The management of established PTS is challenging. Compression therapy, aimed at reducing the underling venous hypertension, remains the mainstay of treatment. This is despite a paucity of high-quality evidence to support its use. Pharmacologic and surgical treatments have also been described, with a number of studies citing symptomatic improvement.

Compression stockings significantly improve hemodynamic performance in post-thrombotic syndrome irrespective of class or length. J Vasc Surg 2013; 58:158-65. [PMID: 23414697 DOI: 10.1016/j.jvs.2013.01.003] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2012] [Revised: 06/06/2012] [Accepted: 06/07/2012] [Indexed: 11/21/2022]
Abstract
BACKGROUND Graduated elastic compression (GEC) stockings have been demonstrated to reduce the morbidity associated with post-thrombotic syndrome. The ideal length or compression strength required to achieve this is speculative and related to physician preference and patient compliance. The aim of this study was to evaluate the hemodynamic performance of four different stockings and determine the patient's preference. METHODS Thirty-four consecutive patients (40 legs, 34 male) with post-thrombotic syndrome were tested with four different stockings (Mediven plus open toe, Bayreuth, Germany) of their size in random order: class 1 (18-21 mm Hg) and class II (23-32 mm Hg), below-knee (BK) and above-knee thigh-length (AK). The median age, Venous Clinical Severity Score, Venous Segmental Disease Score, and Villalta scale were 62 years (range, 31-81 years), 8 (range, 1-21), 5 (range, 2-10), and 10 (range, 2-22), respectively. The C of C0-6EsAs,d,pPr,o was C0 = 2, C2 = 1, C3 = 3, C4a = 12, C4b = 7, C5 = 12, C6 = 3. Obstruction and reflux was observed on duplex in 47.5% legs, with deep venous reflux alone in 45%. Air plethysmography was used to measure the venous filling index (VFI), venous volume, and time to fill 90% of the venous volume. Direct pressure measurements were obtained while lying and standing using the PicoPress device (Microlab Elettronica, Nicolò, Italy). The pressure sensor was placed underneath the test stocking 5 cm above and 2 cm posterior to the medial malleolus. At the end of the study session, patients stated their preferred stocking based on comfort. RESULTS The VFI, venous volume, and time to fill 90% of the venous volume improved significantly with all types of stocking versus no compression. In class I, the VFI (mL/s) improved from a median of 4.9 (range, 1.7-16.3) without compression to 3.7 (range, 0-14) BK (24.5%) and 3.6 (range, 0.6-14.5) AK (26.5%). With class II, the corresponding improvement was to 4.0 (range, 0.3-16.2) BK (18.8%) and 3.7 (range, 0.5-14.2) AK (24.5%). Median stocking pressure (mm Hg) as measured with the PicoPress in class I was 23 (range, 12-33) lying and 27 (range, 19-39) standing (P < .0005) and in class II was 28 (range, 21-40) lying and 32 (range, 23-46) standing (P < .0005). There was a significant but weak correlation (Spearman) between stocking interface pressure measured directly with the PicoPress and the VFI improvement (baseline VFI-compression VFI) at r = .237; P = .005. Twenty-one patients (legs) changed their preference of compression and 38% of these (8/21 patients, 9/21 legs) preferred an AK-GEC stocking. CONCLUSIONS Compression significantly improved all hemodynamic parameters on air plethysmography. However, the hemodynamic benefit did not significantly change with the class or length of stocking. These results support the liberal selection of a GEC stocking based on patient preference.

Abstract
BACKGROUND Graduated compression stockings (GCS) are a valuable means of thromboprophylaxis in hospitalised postoperative surgical patients. But it is still unclear whether knee length graduated compression stockings (KL) or thigh length (TL) stockings are more effective. OBJECTIVES The aim of this review was to systematically analyse the randomised, controlled trials that have evaluated the effectiveness of KL versus TL GCS as a thromboprophylaxis tool in hospitalised patients undergoing various types of surgery. SEARCH METHODS The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched February 2012) and CENTRAL (2012, Issue 1). The authors searched MEDLINE and EMBASE (until 27 February 2012) and they also searched the reference lists of relevant articles to identify additional trials. SELECTION CRITERIA Randomised controlled trials published in any language on KL versus TL GCS used as a thromboprophylaxis tool in hospitalised patients of any age and either gender. DATA COLLECTION AND ANALYSIS Data extraction was undertaken independently by two review authors using data extraction sheets and confirmed by the third review author. MAIN RESULTS Three studies, with a combined total of 496 patients, matched the inclusion criteria for this review. All three included studies evaluated the role of KL and TL in thromboprophylaxis among a group of postoperative patients. These studies showed no significant difference in the ability of the two modalities of leg compression to reduce the incidence of deep vein thrombosis in postoperative patients. In both the fixed-effect model (odds ratio (OR) 1.55, 95% confidence interval (CI) 0.78 to 3.07, P = 0.21) and random-effects model (OR 1.32, 95% CI 0.43 to 4.06, P = 0.63) KL graduated compression stockings were as effective as TL stockings in thromboprophylaxis. However, there was significant heterogeneity (Tau(2) = 0.50; Chi(2) = 4.12, df = 2 (P = 0.13); I(2) = 51%) among trials. Results of this review may be considered weak because there was significant heterogeneity among included trials resulting from inadequate randomisation techniques, allocation concealment, power calculations and the absence of intention-to-treat analysis. AUTHORS' CONCLUSIONS This review found that there is insufficient high quality evidence to determine whether or not KL and TL GCS differ in their effectiveness in terms of reducing the incidence of deep vein thrombosis (DVT) in hospitalised patients. A major multicentre RCT is required to address this issue. In the meantime, the decision on which type of stocking to use in clinical practice is likely to be influenced by factors such as patient compliance, ease of use and cost implications.

Abstract
Venous thromboembolism (VTE) is the most common cause of preventable in-hospital mortality and all hospitalized patients should be VTE risk assessed. The VTE risk should be weighed up against risk of bleeding on an individualized basis to guide choice of prophylaxis. The most common method of mechanical thromboprophylaxis is graduated compression stockings, although others, such as intermittent pneumatic devices, are available. Stockings have the greatest benefit when used in combination with pharmacological prophylaxis. However, stockings are contraindicated in some patients, including those with stroke or peripheral arterial disease. Various options for pharmacological thromboprophylaxis are available. The most commonly used agents are the low-molecular-weight heparins, but newer orally active agents may play an increasing role in the future.

Abstract
Various interdisciplinary guidelines recommend that in-patients at risk of venous thromboembolism should receive pharmacologic prophylaxis. Among the anticoagulants low-molecular-weight heparins (LMWH) and fondaparinux can be considered the medications of choice because of the favorable pharmacokinetic properties when compared with unfractionated heparin. Treatment with vitamin K antagonists has to be interrupted in patients undergoing major surgery or invasive procedures. Oral anticoagulation has to be temporarily replaced by short-acting anticoagulants such as LMWH in order to prevent thromboembolic complications (anticoagulation bridging). Although LMWHs have not been approved for this clinical setting their efficacy and safety has been demonstrated in several recent studies. Detailed recommendations for prophylaxis of venous thromboembolism in otorhinolaryngology are lacking although numerous surgical procedures are considered to be associated with a significant risk of thromboembolism. A strategy for pharmacologic prophylaxis of venous thromboembolism and anticoagulation bridging in otorhinolaryngology is proposed.

Abstract
Following deep vein thrombosis (DVT), one of every two patients will develop postthrombotic syndrome (PTS), which causes remarkable consequences on the socioeconomic level. Residual thrombosis is an important predictor of PTS, and severe early symptoms, old age, obesity, improper anticoagulation, recurrent thrombosis and varicose veins are major risk factors. Diagnosis of PTS is mainly based on the clinical findings for patients with a history of DVT, while in those without it, instrumental diagnosis might help in detecting a previous DVT. Prompt administration of adequate compression elastic stockings (ECS) in patients with symptomatic DVT reduces the frequency of PTS by half. Usually, the management of an established PTS is demanding, and often discouraging. However, when carefully supervised and instructed to wear proper ECS, more than 50% of patients either remain quiescent or improve during long-term follow-up.

Abstract
PURPOSE The purpose of this project was to incorporate current evidence into length selection for graduated compression stockings (GCS) and intermittent pneumatic compression (IPC) devices in order to evaluate and modify current practice. RATIONALE Staff nurses relate concerns regarding the fit and complications related to poorly fitting thigh length GCS and IPC devices. Current evidence supports using knee length over thigh length. DESCRIPTION OF THE PROJECT With the use of Melnyk and Fineout-Overholt's model of evidence-based practice and Norwood's consultation model, current practice was evaluated and practice changes were implemented based on results of a literature review. OUTCOME Knee length will be selected instead of thigh length in general and urology surgery patients. The department of obstetrics and gynecology has taken the practice change under consideration. CONCLUSION Knee-length GCS and IPC devices are as effective as thigh-length GCS and IPC devices, are more comfortable for patients, are easier for staff and patients to use, pose less risk of injury to patients, and are less expensive. Knee-length GCS and IPC devices may safely be used for general, gynecology, and urology surgery patients and are preferable to thigh-length GCS and IPC devices. IMPLICATIONS Venous thromboembolism prophylaxis is an important component of surgical care; proper length selection of GCS and IPC devices should be based on current evidence. This project outlines a method to change practice regarding length selection of GCS and IPC devices.

Abstract
The aim of this overview is to discuss the role of thigh compression for the management of venous and lymphatic diseases. The most important indications for thigh compression are prevention and treatment of sequelae of superficial vein procedures (surgery or endovenous procedures), prevention and therapy of deep vein thrombosis (DVT), post-thrombotic syndrome and lymphoedema. The intended effects depend mainly on narrowing/occlusion of deep and superficial veins on which the body position and the applied pressure play a crucial role. While in the horizontal position thigh veins can be narrowed by the light pressure of a thromboprophylactic stocking, much higher pressure is needed to compress thigh veins effectively during standing and walking. This is shown by magnetic resonance imaging (MRI) performed in the supine and upright position. Using pads, rolls or specially designed devices, the local pressure under conventional compression garments or bandages over a treated vein can be increased considerably. In patients with deep valve incompetence, beneficial haemodynamic effects of strong thigh compression have been demonstrated, but clinical studies in this field are still lacking. Thigh compression reduces oedema in patients with DVT and lymphoedema.

Abstract
OBJECTIVE Graduated compression stockings, when used correctly, have been shown to significantly reduce the risk of deep-vein thrombosis in surgical patients, but they can be harmful to skin and may even increase the risk of thrombosis if the wrong size is used. The authors sought to determine whether nurses correctly size and apply the stockings, whether problems were more common in knee- or thigh-length stockings, and whether nurses adequately educate patients on the usage of the stockings. METHODS The researchers used a comparative, descriptive design to study 142 hospitalized postoperative patients; 37 had thigh-length and 105 had knee-length stockings. They assessed usage of the stockings and compared four separate leg measurements against the manufacturer's sizing chart to determine whether stockings that had been applied were the correct size. They also asked patients to rate the comfort of the stockings and to describe their purpose. RESULTS The graduated compression stockings were used incorrectly (for example, they were wrinkled or the gusset was in the wrong place) in 29% of the patients and sized incorrectly in 26% of the patients. These problems were more common with the thigh-length stockings and in overweight patients. More patients who had thigh-length stockings found them uncomfortable than did those who had knee-length stockings, and 20% of patients didn't understand the stockings' purpose. CONCLUSIONS The authors recommend that nurses ensure that graduated compression stockings are properly sized and used, that the education of both nurses and patients regarding the stockings be improved, and that knee-length stockings be the standard length used.

Abstract
Long-distance travel is becoming increasingly common. Whatever the means of transport, any long journey will be associated with "travel fatigue". The symptoms associated with this phenomenon result from a changed routine (particularly sleep lost and meals) and the general disruption caused by travel. Planning any trip well in advance will minimise many of these problems, but some factors are less easy to guard against. These problems include sitting in cramped and uncomfortable conditions and, with flights, the hypoxic environment in the cabin. After arrival at the destination in another country, there can be problems coping with the local language, alterations in food and different customs. If the flight has crossed the equator, then there is likely to be a change in season and natural lighting and, if it has crossed several time zones, there will also be the problem of "jet lag", caused by a transient desynchrony between the "body clock" and the new local time. Moreover, the new environment might differ from the place of departure with regard to ambient temperature and humidity, altitude, natural lighting (including ultraviolet radiation) and pollution. The traveller needs to be aware of these changes before setting off, so that appropriate preparations (clothing, for example) can be made.

Abstract
Older age is an important factor in preparing travelers owing not only to physiologic changes and the increased probability of underlying medical conditions and prescription medications but also to immune status with regard to naturally acquired immunity versus immunization for vaccine-preventable diseases. Cardiovascular events (including myocardial infarctions and cerebrovascular accidents) account for most deaths abroad, followed by injuries. To plan for healthy travel, international travelers should be advised to seek care at least 4 to 6 weeks before departure. Travel medicine is a dynamic field because conditions worldwide are subject to rapid change. Clinicians must maintain a current base of knowledge if they will be regularly advising travelers or must set a threshold for referral to a travel medicine specialist.

Abstract
Today, it is possible to define certain risk groups for the development of venous thromboembolism, most studies having been conducted on post-operative venous thromboembolism. Nonetheless, the risk classification is rather inexact, resulting in many patients receiving prophylaxis who would not have gone on to develop the complication. However, the current prophylactic methods are safe and can therefore also be used in the post-operative situation. The dominating pharmacological substances are unfractionated heparin, low-molecular-weight heparins and the pentasaccharide fondaparinux. In some situations (such as elective hip surgery and likely hip fracture surgery, and in many cases where malignant diseases in the abdomen/pelvis have been operated upon), extended prophylaxis for 1 month should be considered.
