RESUMEN
AIM: To examine the cost benefit conferred by the perioperative administration of intravenous tranexamic acid (TXA) in lower limb arthroplasty. METHODS: This study evaluates the use of TXA in 200 consecutive lower limb arthroplasties performed in a single surgeon series. The initial 100 patients (control group) underwent surgery without perioperative administration of TXA while the subsequent 100 patients (TXA group) all received 1 g TXA at the time of induction of anaesthesia. Pre- and post-operative haemoglobin, platelet count, haematocrit, the use of blood product post-operatively, length of stay were examined. A financial analysis of both groups was then undertaken. RESULTS: The mean age of patients in both groups was 63 ± 13 years. There were no significant differences between groups in terms of gender (P = 0.47), proportion of total hip replacement to total knee replacement (P = 0.25) or pre-operative haemoglobin (P = 0.43). In the control group, the transfusion rate was 22%. In the TXA group, the transfusion rate dropped to 2% (P < 0.001). The mean post-operative haemoglobin was 10.82 ± 1.55 g/dL in the control group vs 11.33 ± 1.27 g/dL in the TXA group (P = 0.01). The total cost of transfused blood products was 11055 and 603 respectively. The mean length of stay in the control group was 6.53 ± 5.93 d vs 5.47 ± 4.26 d in the TXA group (P = 0.15) leading to an estimated financial saving of 114586. There was one pulmonary embolus in the control group and one deep venous thrombosis in the TXA group. CONCLUSION: Intravenous TXA reduces blood loss in lower limb arthroplasty. This leads to lower transfusion rates, shorter length of stay in hospital and significant financial savings.
RESUMEN
BACKGROUND: The penalty points system (PPS) was introduced in 2002 in an attempt to reduce the increasing rate of road traffic accident (RTA) related fatalities and serious injuries. Points are awarded based on the severity of the offence and are cumulative. A total of 12 points results in the disqualification from driving. OBJECTIVE: A few studies have looked at the immediate or short term impact of PPS on trauma services or specific injuries such as spine trauma in Ireland. Little data is available on the long term effect of the PPS. The aim of this study is to see if the PPS system has had an influence on the number of pelvic injuries referred to our unit for surgical intervention and if this influence is sustained in the longer term. MATERIALS AND METHODS: A retrospective review of all pelvic and acetabular injuries admitted to our unit from 1999 to 2008 was undertaken. The mechanism of injury, the site and patient demographics were noted. RESULTS: A total of 467 patients were identified over the ten year period. 454 patients were included in the study. There was a significant male preponderance of 76%. Mean age was 36.5 years (range 16 to 83). RTA's were the cause in 74% (n = 335) of the cases. The annual work load remained similar over the years. There has been a reduction in the number of RTA related pelvic injuries. There have been notable drops in the number of these cases corresponding to the introduction of the PPS and its subsequent expansion. The number of pelvic injuries due to falls continues to rise. CONCLUSION: The introduction of the PPS and its subsequent expansion has had a positive influence on the number of RTA related pelvic trauma. Continued surveillance and enforcement of the PPS is important for a sustained benefit from it in the long term.
RESUMEN
Bilateral simultaneous ruptures are rare comprising less than 1% of all Achilles tendon ruptures. Risk factors for bilateral ruptures include chronic diseases and medications such as corticosteroids and fluoroquinolones. There is little in the literature on the long-term functional outcome of bilateral Achilles tendon ruptures. This article present a series of 3 cases of simultaneous and spontaneous bilateral Achilles tendon ruptures with a minimum of 5-year follow up suggesting a good functional outcome.
