Clinical assessment of venous thromboembolic risk in surgical patients. The score has been validated in several subsets of surgical specialities, such as general, vascular, neurological, ICU or plastic and is the the risk assessment model recommended by the 2012 Chest guidelines for VTE prevention.Ĭaprini JA, Arcelus JI, Hasty JH, Tamhane AC, Fabrega F. Pneumatic compression devices AND low dose heparin OR low molecular weight heparin Pneumatic compression devices ± graduated compression stockings Caprini ScoreĮarly frequent ambulation only, OR at discretion of surgical team: Pneumatic compression devices OR graduated compression stockings Pannucci’s 2017 study was a meta-analysis including 14,776 patients and found that VTE risk varied from 0.7% to 10.7% among surgical patients (with or without) chemoprophylaxis. have identified recommended prophylaxis measures for each risk group. offer a detailed interpretation of the scores, the VTE risk, whilst Bahl et al. The higher the total score, the greater the risk of VTE. The score is calculated by summing the point values. The original score is derived from a prospective study of 538 general surgery patients (admitted for general, urologic, gynecologic, orthopedic surgery and head and neck procedures).Īnd there are several risk factors taken in consideration, weighted (for the degree of risk posed) with scores from 0 to 5. The significance and usage of the score is the more important as the risk of VTE can be of up to 30% in some surgical patients. To help prevent mistakes when purchasing or changing seatposts, this article explains what kinds of seatpost diameters are most commonly used and how they are measured.The Caprini Score is based on the Venous Thromboembolism Risk Factor Assessment that predicts risk and probability of VTE, defined as deep vein thrombosis DVT or pulmonary embolism. Only diameter (width) is dealt with here. The length of the seatpost depends on frame geometry (design) and size – i.e. how much the saddle needs to be raised from the end of the seat tube. “ seat tube” – the tube in the frame that holds the seatpost.įor seatpost height in terms of bicycle fitting, see: Setting up comfortable riding position.Ī separate article explains the maximum amount of seatpost extension from the frame (minimal insertion length).“ seatpost” – the post the saddle is mounted on. Picture 1 shows a seatpost (1), and a seat tube (2): The first bicycle frames were made mostly from steel, with steel tubes of a standard (outer) diameter. The British and Italian standard diameter for seat tubes was 1 1/8″ (28.6 mm). Old US bicycles (mostly BMX and older bikes that used one-piece cranks) was 1″ (25.4 mm). Standard outer diameter dimensions were important so that derailleur clamps etc. could be made in exact matching sizes (derailleur clamp inner diameter needs to match the seat tube’s outer diameter). Higher quality frames are usually made with thinned down tube walls to reduce the weight of the frame. This meant that a wider seatpost diameter usually meant a higher quality (and lighter) frame. So high-quality frames with 1 1/8″ seat tubes usually had 27.2 mm wide seatposts.Ī more modern trend, mostly on mountain bikes, where stronger seatposts are required (without too much extra weight) led to a new “oversized” standard of 27.4 mm (and wider).
