Association of preoperative anemia and increased risk of blood transfusion and length of hospital stay in adults undergoing hip and knee arthroplasty: An observational study in a single tertiary center.

BACKGROUND AND AIMS: Anemia is a common feature in patients presenting for major elective surgery, and it is considered an independent risk factor associated with adverse outcomes. Although several studies suggest that preoperative anemia is associated with poor outcomes after elective orthopedic surgery, data are still scarce in middle- and low-income countries where this problem may be even greater. The objective of this study was to evaluate the impact of preoperative anemia in clinical outcomes in patients submitted to hip and knee arthroplasty in a single tertiary hospital. METHODS: Medical records of 234 adult patients submitted to knee and hip arthroplasty from January 2018 to July 2020 were retrospectively reviewed. Patient's demographics (ie, age and gender), pre- and postoperative hemoglobin level (Hb), allogeneic red blood cell (RBC) transfusion, intensive care admission, length of hospital stay, hospital readmissions, and mortality up to 30 days after the surgery were analyzed. Outcomes were evaluated according to preoperative anemia status based on World Health Organization (WHO) criteria. RESULTS: Mean age was 70 years with a slight female predominance (57.6%). The prevalence of anemia was 30.7% (72/234) being more prevalent in female (33.3% vs 26.7%). Preoperative anemia was significantly associated with greater rate of blood transfusion (34.5% vs 5.6%; P = .001), prolonged length of hospital stay (6.48 days vs 3.36 days; P = .001), and higher rate of intensive care unit admission (47.2% and 29.6% P = .009). Preoperative anemia had no effect on 30-day readmission and mortality for both males and females. CONCLUSIONS: Our retrospective study demonstrated that preoperative anemia is a common problem among orthopedic patients and is associated with increased transfusion risk and worse outcomes. Strategies to identify and treat anemic patients before elective surgery are critical to improving clinical outcomes.

Relato de caso: otoliquorreia espontânea em adulto / Case study spontaneous otoliquorrhea in adult

Introdução: As fístulas liquóricas otológicas espontâneas (FLOEs) são entidades raras. Geralmente manifestam-se em crianças com meningite e perda sensorioneural profunda e em adultos com quadro de otite média com efusão. Objetivo: Descrever o quadro clínico, o diagnóstico e o tratamento cirúrgico de uma paciente com FLOE. Relato do Caso: Paciente do sexo feminino, 57 anos, com história de hipoacusia, plenitude aural e tinnitus à direita há 10 anos. Após colocação de tubo de ventilação à direita em outro serviço, iniciou otorreia líquida, transparente e constante em grande quantidade. O diagnóstico foi realizado através da cisternocintilografia, sugestiva de fístula liquórica; e da cisternotomografia que mostrou área de deiscência óssea em região de tegmen tympani à direita, velamento parcial de células mastóideas e de orelha média à direita, além concentração do meio de contraste no espaço sub-aracnoídeo à direita menor em relação ao lado esquerdo. Através de via transmastoídea foi localizada fístula liquórica e meningoencefalocele na região de tegmen tympani à direita. O fechamento da fístula foi realizado através do uso de retalho de músculo temporal, cola de fibrina e Surgicel®. Comentários Finais: Em adultos com história clínica sugestiva de otite média com efusão recorrente, a hipótese diagnóstica de fístula liquórica deve ser levantada. A investigação deve prosseguir com exames de imagem, destacando-se a cisternotomografia. O tratamento cirúrgico nesta paciente, através da técnica transmastoídea, se revelou eficaz a curto e a longo prazo...

Introduction: The spontaneous otological CSF leaks are rare entities. Usually they manifest themselves in children with meningitis and deep sensorineural hearing loss and in adults with middle otitis and effusion clinical picture. Objective: To describe the clinical picture, diagnosis and surgical treatment of a patient with CSF otological. Case Report: A female sex patient, 57 years old, with hearing loss, aural fullness and right ear tinnitus case history 10 years ago. After insertion of tympanostomy tubes on the right in another service, it began liquid, transparent and constant otorrhea in large quantities. The diagnosis was performed by suggestive cisternoscintigraphy of CSF leak, and by cisternography that showed that the area of bone dehiscence in the tegmen tympani region to the right, partial opacification of mastoid cells and middle ear to the right, besides concentration of contrast medium in sub-arachnoid space to the lower right compared to the left side. Through transmastoid via was located the CSF leak and meningoencephalocele in the region of the right tegmen tympani. The closure of the fistula was accomplished through the use of the temporal muscle flap, fibrin glue and Surgicel®. Final Comments: In adults with symptoms suggestive of recurrent otitis media with effusion, the diagnosis of CSF fistula should be raised. The research should proceed with imaging, highlighting the CTC. Surgical treatment in this patient using the transmastoid technique has proved effective in the short and long term...
