Peri-operative treatment of anaemia in major orthopaedic surgery: a practical approach from Spain

In patients undergoing major orthopaedic surgery, pre-operative anaemia, peri-operative bleeding and a liberal transfusion policy are the main risk factors for requiring red blood cell transfusion (RBCT). The clinical and economic disadvantages of RBCT have led to the development and implementation of multidisciplinary, multimodal, individualised strategies, collectively termed patient blood management, which aim to reduce RBCT and improve patients' clinical outcome and safety. Within a patient blood management programme, low pre-operative haemoglobin is one of the few modifiable risk factors for RBCT. However, a survey among Anaesthesia Departments in Spain revealed that, although pre-operative assessment was performed in the vast majority of hospitals, optimisation of haemoglobin concentration was attempted in <40% of patients who may have benefitted from it, despite there being enough time prior to surgery. This indicates that haemoglobin optimisation takes planning and forethought to be implemented in an effective manner. This review, based on available clinical evidence and our experience, is intended to provide clinicians with a practical tool to optimise pre-operative haemoglobin levels, in order to minimise the risk of patients requiring RBCT. To this purpose, after reviewing the diagnostic value and limitations of available laboratory parameters, we developed an algorithm for the detection, classification and treatment of pre-operative anaemia, with a patient-tailored approach that facilitates decision-making in the pre-operative assessment. We also reviewed the efficacy of the different pharmacological options for pre-operative and post-operative management of anaemia. We consider that such an institutional pathway for anaemia management could be a viable, cost-effective strategy that is beneficial to both patients and healthcare systems

The objective of this study was to explore fluid therapy management during the perioperative period in our country. Methods We designed the Fluid Day study as a cross-sectional, multicentre, observational study. The study was performed in 131 Spanish hospitals in February 2019. We included adult patients undergoing general anaesthesia for either elective or non-elective surgery. Demographic variables were recorded, as well as the type and total volume of fluid administered during the perioperative period and the monitorization used. To perform the analysis, patients were categorized by risk group. Results We recruited 7291 patients, 6314 of which were included in the analysis; 1541 (24.4%) patients underwent high-risk surgery, 1497 (23. 7%) were high risk patients, and 554 (8.7%) were high-risk patients and underwent high-risk surgery; 98% patients received crystalloids (80% balanced solutions); intraoperative colloids were used in 466 patients (7.51%). The hourly intraoperative volume in mL/kg/h and the median [Q1; Q3] administered volume (mL/kg) were, respectively, 6.67 [3.83; 8.17] ml/Kg/h and 13.9 [9.52;5.20] ml/Kg in low-risk patients undergoing low- or intermediate-risk surgery, 6 [4.04; 9.08] ml/Kg/h and 15.7 [10.4;24.5] ml/Kg in high- risk patients undergoing low or intermediate-risk surgery, 6.41 [4.36; 9.33] ml/Kg/h and 20.2 [13.3;32.4] ml/Kg in low-risk patients undergoing high-risk surgery, and 5.46 [3.83; 8.17] ml/Kg/h and 22.7[14.1;40.9] ml/Kg in high-risk patients undergoing high- risk surgery . We used advanced fluid monitoring strategies in 5% of patients in the intraoperative period and in 10% in the postoperative period. Conclusions The most widely used fluid was balanced crystalloids. Colloids were used in a small number of patients. Hourly surgery volume tended to be more restrictive in high-risk patients but confirms a high degree of variation in the perioperatively administered volume. Scarce monitorization was observed in fluid therapy management.Open Access funding enabled and organized by SEDAR

Gender differences in GPs' strategies for coping with the stress of the COVID-19 pandemic in Catalonia: A cross-sectional study

The Covid-19 pandemic has increased stress levels in GPs, who have resorted to different coping strategies to deal with this crisis. Gender differences in coping styles may be contributing factors in the development of psychological distress.To identify differences by gender and by stress level in coping strategies of GPs during the Covid-19 pandemic.A cross-sectional, web-based survey conducted with GPs in Catalonia (Spain), in June-July 2021. via the institution's email distribution list, all GPs members of the Catalan Society of Family and Community Medicine were invited to complete a survey assessing sociodemographic, health and work-related characteristics, experienced stress (Stress scale of the Depression, Anxiety and Stress Scales-DASS 21) and the frequency of use of a range of coping strategies (Brief-COPE) classified as problem-focused, emotion-focused and avoidant strategies, some of which are adaptive and others maladaptive. We compared the scores of each strategy by gender and stress level using Student's t-test.Of 4739 members, 522 GPs participated in the study (response rate 11%; 79.1% women; mean age = 46.9?years, SD?=?10.5). Of these, 41.9% reported moderate-severe stress levels. The most common coping strategies were acceptance, active coping, planning, positive reframing and venting. More frequently than men, women resorted to emotional and instrumental support, venting, distraction and self-blame, whereas men used acceptance and humour more commonly than women. Moderate-severe stress levels were associated with non-adaptive coping, with increased use of avoidance strategies, self-blame, religion and venting, and decreased use of positive reframing and acceptance.The most common coping strategies were adaptive and differed by gender. However, highly stressful situations caused maladaptive strategies to emerge

Optimización de la hemoglobina preoperatoria en cirugía ortopédica mayor utilizando hierro intravenoso con o sin eritropoyetina. Estudio epidemiológico

Objetivo: Evaluar la efectividad del tratamiento con hierro intravenoso, solo o asociado a eritropoyetina (rHuEPO), mediante el incremento de hemoglobina (Hb). Como objetivo secundario se analizó la relación del incremento de Hb con los parámetros utilizados para evaluar la anemia. Material y método: Estudio observacional retrospectivo realizado en 2 centros entre enero de 2005 y diciembre de 2009. Se incluyeron pacientes sometidos a cirugía ortopédica electiva con déficit de hierro y que fueron tratados con hierro sacarosa intravenosos solo o asociado a rHuEPO. Se analizó la efectividad del tratamiento mediante la diferencia entre la Hb basal y la Hb previa a la cirugía y se valoró la relación entre los parámetros hematimétricos y del metabolismo del hierro con la efectividad del tratamiento. Resultados: Se incluyeron 412 pacientes que recibieron una mediana de 800mg de hierro sacarosa. A 125 pacientes (30,4%) se les asoció 2,4 viales de rHuEPO. El incremento de Hb fue de 0,8 (1,1) g/dL en los pacientes tratados con hierro intravenoso y de 1,5 (1,3) g/dL en los que se asoció rHuEPO (p<0,01). El incremento de Hb en los pacientes tratados con hierro se correlacionó con el porcentaje de hematíes hipocromos (r=0,52) y el valor del receptor soluble de la transferrina (r=0,59). Conclusiones: La efectividad del tratamiento con hierro sacarosa en pacientes con déficit de hierro para la optimización de la Hb preoperatoria fue moderada, siendo mayor con la administración adyuvante de eritropoyetina. La determinación de los parámetros funcionales del estado del hierro nos podría guiar para mejorar la efectividad del tratamiento

Guía de práctica clínica para la elección del fluido de restauración volémica perioperatoria en los pacientes adultos intervenidos de cirugía no cardiaca

Esta Guía de Práctica Clínica responde a preguntas clínicas sobre seguridad en la elección de fluido (cristaloide, coloide o Hidroxietilalmidón 130) en pacientes que precisan restauración volémica en el periodo perioperatorio de cirugía no cardiaca. A partir del resumen de la evidencia, se elaboraron las recomendaciones siguiendo la metodología GRADE. En esta población se sugiere la fluidoterapia basada en la administración de cristaloides, (recomendación débil, calidad de la evidencia baja). En las situaciones en las que la restauración volémica no se alcance sólo con cristaloides, se sugiere utilizar coloides sintéticos (Hidroxietilalmidón 130 o gelatina fluida modificada) en lugar de Albúmina 5% (recomendación débil, calidad de la evidencia baja). La elección y dosificación de coloide deberán basarse en las características del producto, comorbilidad del paciente y experiencia del anestesiólogo

Metabolic Syndrome as a Cardiovascular Disease Risk Factor: Patients Evaluated in Primary Care

To estimate the prevalence of metabolic syndrome (MS) in a population receiving attention in primary care centers (PCC) we selected a random cohort of ostensibly normal subjects from the registers of 5 basic-health area (BHA) PCC. Diagnosis of MS was with the WHO, NCEP and IDF criteria. Variables recorded were: socio-demographic data, CVD risk factors including lipids, obesity, diabetes, blood pressure and smoking habit and a glucose tolerance test outcome. Of the 720 individuals selected (age 60.3 ± 11.5 years), 431 were female, 352 hypertensive, 142 diabetic, 233 pre-diabetic, 285 obese, 209 dyslipemic and 106 smokers. CVD risk according to the Framingham and REGICOR calculation was 13.8 ± 10% and 8.8 ± 9.8%, respectively. Using the WHO, NCEP and IDF criteria, MS was diagnosed in 166, 210 and 252 subjects, respectively and the relative risk of CVD complications in MS subjects was 2.56. Logistic regression analysis indicated that the MS components (WHO set), the MS components (IDF set) and the female gender had an increased odds ratio for CVD of 3.48 (95CI%: 2.26–5.37), 2.28 (95%CI: 1.84–4.90) and 2.26 (95%CI: 1.48–3.47), respectively. We conclude that MS and concomitant CVD risk is high in ostensibly normal population attending primary care clinics, and this would necessarily impinge on resource allocation in primary care

Validation of bioelectrical impedance analysis for body composition assessment in children with obesity aged 8-14y

BACKGROUND & AIMS: The aim was to generate a predictive equation to assess body composition (BC) in children with obesity using bioimpedance (BIA), and avoid bias produced by different density levels of fat free mass (FFM) in this population. METHODS: This was a cross-sectional validation study using baseline data from a randomized intervention trial to treat childhood obesity. Participants were 8 to 14y (n = 315), underwent assessments on anthropometry and BC through Air Displacement Plethysmography (ADP), Dual X-Ray Absorptiometry and BIA. They were divided into a training (n = 249) and a testing subset (n = 66). In addition, the testing subset underwent a total body water assessment using deuterium dilution, and thus obtained results for the 4-compartment model (4C). A new equation to estimate FFM was created from the BIA outputs by comparison to a validated model of ADP adjusted by FFM density in the training subset. The equation was validated against 4C in the testing subset. As reference, the outputs from the BIA device were also compared to 4C. RESULTS: The predictive equation reduced the bias from the BIA outputs from 14.1% (95%CI: 12.7, 15.4) to 4.6% (95%CI: 3.8, 5.4) for FFM and from 18.4% (95%CI: 16.9, 19.9) to 6.4% (95% CI: 5.3, 7.4) for FM. Bland-Altman plots revealed that the new equation significantly improved the agreement with 4C; furthermore, the observed trend to increase the degree of bias with increasing FM and FFM also disappeared. CONCLUSION: The new predictive equation increases the precision of BC assessment using BIA in children with obesity

Intraoperative tranexamic acid use in major spine surgery in adults: a multicentre, randomized, placebo-controlled trial

Background. Perioperative tranexamic acid (TXA) use can reduce bleeding and transfusion requirements in several types of surgery, but level I evidence proving its effectiveness in major spine surger y is lacking. This study was designed to investigate the hypothesis that TXA reduces perioperative blood loss and transfusion requirements in patients undergoing major spine procedures. Methods. We conducted a multicentre, prospective, randomized double -blind clinical trial, comparing TXA with placebo in posterior instrumented spine surgery. Efficacy was determined based on the total number of blood units transfused and the perioperative blood loss. Other variables such as the characteristics of surgery, length of hospital stay, and complications were also analysed. Results. Ninety-five patients undergoing posterior instrumented spine surgery (fusion of >3 segments) were enrolled and randomized: 44 received TXA (TXA group) and 51 received placebo (controls). The groups were comparable for duration of surgery, number of levels fused, and length of hospitalization. Transfusion was not required in 48% of subjects receiving TXA compared with 33% of controls (P=0.05). Mean number of blood units transfused was 0.85 in the TXA group and 1.42 with placebo (P=0.06). TXA resulted in a significant decrease in intraoperative bleeding (P=0.01) and total bleeding (P=0.01)relative to placebo. The incidence of adverse events was similar in the two groups. Conclusions. TXA did not significantly reduce transfusion requirements, but significantly reduced perioperative blood loss in adults undergoing major spinal surgery
