Odds ratios were then calculated to determine how well each factor could predict the need for postoperative blood transfusion. Results:?Blood transfusions were required in 55 patients (20.8%). Univariate analysis identified female gender, age �� 70 years, height http://www.selleckchem.com/products/ganetespib-sta-9090.html Of these, the strongest predictors were preoperative haemoglobin 70 years (OR 2.63; CI 1.41�C4.88, p = 0.002) and weight http://www.selleck.cn/products/cobimetinib-gdc-0973-rg7420.html This would allow for appropriate implementation of perioperative blood management strategies. Kaihan Yao, Rhys Clark, Hemant Khanna and Adrian Trivett Monash Health, Victoria Introduction & Aims:?Fever is common after hip or knee arthroplasties and is potentially concerning. As such, clinicians often further investigate the cause of fever, which may be of limited value in an otherwise asymptomatic patient. Our study aims to determine the incidence and clinical significance of fever post primary hip and knee arthroplasties. Methods:?We retrospectively analysed the hospital records of patients who underwent 157 consecutive elective primary unilateral hip- or knee-joint arthroplasty at our institution between 1 January 2012 and 1 May 2013. The records were reviewed for: (i) documentation of postoperative febrile episodes, (ii) specific investigations ordered to work-up the fever and (iii) diagnosis made accounting for the fever. Results:?Thirty-eight of the 157 patients (24.2%) developed fever following their arthroplasty. Only 2 of the 38 patients http://www.selleckchem.com/products/poziotinib-hm781-36b.html were found to have clear causes for their fever and both patients demonstrated appropriate symptoms as well as signs. The remaining 36 patients were asymptomatic and did not have any clinical signs accounting for potential causes of fever. Despite these, 19 of the 36 patients were further investigated, with no positive results yielded. Conclusions:?Although fever is common following hip or knee arthroplasties, investigations to identify the cause of fever are generally not indicated. Investigations are only warranted if localising signs or symptoms are present. Yew Ming Chong, Chong Tan and Phong Tran Western Health, Melbourne, Victoria Purpose:?Pain after hip arthroscopy is known to be severe in the early postoperative period, but rapidly improves as peri-articular soft tissue swelling resolves. We hypothesized that higher arthroscopic fluid infusion pressure results in a larger fluid volume infused and is proportional to patient's acute postoperative pain.
