Thromboprophylaxis in day surgery

AbstractMany patients undergoing day surgery are at low-risk of venous thromboembolic events. However, given that pulmonary embolism is the most common preventable cause of hospital death, the risk-benefit profile of thromboprophylaxis should be accurately balanced. In this narrative review, we will briefly discuss some topics of thromboprohylaxis in ambulatory surgical procedures: venous thromboembolic risk stratification, venous thromboembolic risk during laparoscopic surgery, use of antithrombotic drugs in case of neuraxial anesthesia/analgesia, American College of Chest Physicians recommendations for thromboprophylaxis

Isolated office hypertension : A 3-year follow-up study

The study aimed to evaluate, over a 3-year period, the progression towards sustained hypertension and left ventricular (LV) changes in patients with isolated office (IO) hypertension (office BP140 and/or 90 mmHg, daytime BP130/80 mmHg). After 3 years from the basal evaluation, 38 subjects with basal normal BP and 42 subjects with basal IO hypertension underwent a second 24-h BP monitoring and echocardiography; 19 patients of the basal IO hypertension group were not revaluated because they had already developed ambulatory hypertension and were on antihypertensive treatment. At the second evaluation, the 38 normotensive subjects had unchanged BP and LV parameters; 25 IO hypertensives have developed sustained hypertension. Considering them together with the 19 patients already treated, 72% of 61 IO hypertensives developed ambulatory hypertension over a 3-year period. The patients who subsequently developed hypertension differed from the group who did not only for lower basal values of LV diastolic parameters; all the patients with basal LV hypertrophy and/or preclinical diastolic impairment subsequently developed sustained hypertension. In conclusion, IO hypertensive patients show a high rate of progression towards sustained hypertension. Basal LV hypertrophy and/or preclinical diastolic dysfunction were the only markers of a greater risk of becoming hypertensives

Statins, fibrates, and venous thromboembolism: a meta-analysis

The aim is to make a systematic review of the literature to assess the effect of lipid-lowering drugs on venous thromboembolism (VTE) occurrence. MEDLINE and EMBASE databases were searched to identify studies that evaluated the effect of lipid-lowering drugs, in particular statins and fibrates, on VTE risk until April 2009. A scoring system was used to divide studies into two quality categories. Odds ratios (ORs) and 95% confidence intervals (CIs) were then calculated and pooled using a fixed and a random-effects model. Statistical heterogeneity was evaluated through the use of I(2) statistics. Three randomized controlled trials (RCTs), three cohort, and eight case-control studies were included in our systematic review, for a total of 863 805 patients. Statins use significantly reduced VTE risk [OR, 0.81; 95% CI, 0.66-0.99, random-effect model)]. There was a very high heterogeneity among the studies (I(2) > 80%). The use of fibrates was associated with a significant increase in the risk of VTE (OR, 1.58; 95% CI, 1.23-2.02), without heterogeneity (I(2) = 0%). Data on other lipid-lowering drugs were lacking. This meta-analysis of available literature suggests that statins may lower the risk of VTE, whereas fibrates may increase this risk. Due to several methodological limitations, this conclusion should be considered with caution, and additional, specifically designed RCTs are warrante
