Purpose: This study reports the results of a multimodal thromboprophylaxis protocol for lower limb arthroplasty involving risk stratification, intraoperative calf compression, aspirin prophylaxis and early (within 4 h) post-operative mobilisation facilitated by the use of local infiltration analgesia. The study also aimed to identify risk factors for venous thromboembolism (VTE) within a 3-month period following surgery for patients deemed not at elevated risk. Methods: Patients undergoing knee/hip arthroplasty or hip resurfacing were preoperatively screened for VTE risk factors, and those at standard risk were placed on a thromboprophylaxis protocol consisting of intraoperative intermittent calf compression during surgery, 300 mg/day aspirin for 6 weeks from surgery and early mobilisation. Patients were screened bilaterally for deep vein thrombosis (DVT) on post-operative days 10–14. If proximal DVT was detected, patients were anticoagulated and outcomes were recorded. Symptomatic VTE within 3 months of surgery were recorded separately. Patient notes were retrospectively collated and cross-validated against ultrasound reports. Results: At initial screening, the rate of proximal DVT was 0.54% (1.1% for knee and 0.27% for hip), and distal DVT was 6.63% (20.11% for knee and 2.31% for hip). One small, nonfatal pulmonary embolism (PE) was detected within 3 months of surgery (0.28% of total knee arthroplasty patients or 0.07% of total). All proximal DVTs were treated successfully with anticoagulants; however, one patient suffered a minor PE approximately 10 months post-operatively. Regression analysis identified knee implant and advanced age as independent risk factors for VTE in this cohort. Conclusion: Although knee arthroplasty patients remained at higher risk than hip replacement/resurfacing patients, the incidence and outcomes of VTE remained positive compared with protocols involving extended immobilisation, and episodes of PE were extremely rare. Thus, we conclude that patients at standard preoperative risk of VTE may safely be taken through the post-operative recovery process with a combination of intraoperative mechanical prophylaxis, early mobilisation and post-operative aspirin, with closer attention required for older patients and those undergoing knee surgery.

Infiltration Analgesia

Fast track arthroplasty is a holistic approach to patients who undergo total hip and knee arthroplasty, a journey or care that begins with setting patient’s expectation, optimising medical status, using intraoperative local anaesthetic infiltra-tion, decreasing narcotics usage either in spinal or post-operative medication, discouraging usage of patient controlled analgesia or urinary catheters, encouraging day of operation mobilisation and optimising post-operative physiotherapy protocols. The use of local infiltration analgesia (LIA) is a good alternative compared to other traditional pain management techniques. The purpose of adoption of LIA technique is to provide comfort from the trauma associated with hip and knee arthroplasty particularly for the first 36 h post-operatively, during the time of high post-operative pain, to facilitate increased post-operative mobilisation and function. LIA is safe and effective to achieve good outcomes, early mobilisation and decreasing length of stay without jeopardising clinical outcomes. This chapter discusses LIA and its multimodal approach to analgesia, regional anaesthesia and early mobilisation that improves overall patient experience and satisfaction. The chapter discusses LIA techniques, wound catheter placement, and postoperative protocol to achieve fast track hip and knee arthroplasty.

AbstractUrinary tract infections (UTIs) are among the most common bacterial infections and a frequent cause for hospitalization in the elderly. The aim of our study was to analyse epidemiological, microbiological, therapeutic, and prognostic of elderly hospitalised patients with and to determine independent risk factors for multidrug resistance and its outcome implications. A single-centre observational prospective cohort analysis of 163 adult patients hospitalized for suspected symptomatic UTI in the Departments of Internal Medicine, Infectious Diseases and Short-Stay Medical Unit of a tertiary hospital was conducted. Most patients currently admitted to hospital for UTI are elderly and usually present high comorbidity and severe dependence. More than 55% met sepsis criteria but presented with atypical symptoms. Usual risk factors for multidrug resistant pathogens were frequent. Almost one out of five patients had been hospitalized in the 90 days prior to the current admission and over 40% of patients had been treated with antibiotic in the previous 90 days. Infection by MDR bacteria was independently associated with the previous stay in nursing homes or long-term care facilities (LTCF) (OR 5.8, 95% CI 1.17–29.00), permanent bladder catheter (OR 3.55, 95% CI 1.00–12.50) and urinary incontinence (OR 2.63, 95% CI 1.04–6.68). The degree of dependence and comorbidity, female sex, obesity, and bacteraemia were independent predictors of longer hospital stay. The epidemiology and presentation of UTIs requiring hospitalisation is changing over time. Attention should be paid to improve management of urinary incontinence, judicious catheterisation, and antibiotic therapy.

Spinal Epidural

A 76-year-old woman with a rare case of spinal epidural abscess (SEA) that had no risk factors for such type of infection, presented symptoms of back pain, progressive neurological deficit of the lower limb and loss of sphincter control. A gadolinium-enhanced MRI confirmed the diagnosis of an SEA. The patient underwent laminectomy with surgical drainage, where cultures showed the presence of Aggregatibacter aphrophilus, a bacterium of the HACEK group (Haemophilus species, Aggregatibacter species, Cardiobacterium hominis, Eikenella corrodens, and Kingella species), rarely involved in SEA. Following surgery, the patient was treated with intravenous ceftriaxone for 6 weeks, and this gave excellent results.
