RESUMO
PURPOSE: Perioperative management of patients medicated with antithrombotics requiring elective intracranial procedures is challenging. We ought to (1) identify the clinical practice guidelines (CPGs) and recommendations (CPRs) on perioperative management of antithrombotic agents in elective intracranial surgery and (2) assess their methodological quality and reporting clarity. METHODS: The study was conducted following the 2020 PRISMA guidelines for a systematic review and has been registered (PROSPERO, CRD42023415710). An electronic search was conducted using PubMed, Scopus, and Google Scholar. The search terms used were "adults," "antiplatelets," "anticoagulants," "guidelines," "recommendations," "english language," "cranial surgery," "brain surgery," "risk of bleeding," "risk of coagulation," and "perioperative management" in all possible combinations. The search period extended from 1964 to April 2023 and was limited to literature published in the English language. The eligible studies were evaluated by three blinded raters, by employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool. RESULTS: A total of 14 sets of guidelines were evaluated. Two guidelines from the European Society of Anaesthesiology and one from the American College of Chest Physicians found to have the highest methodological quality and reporting clarity according to the AGREE-II tool. The interrater agreement was good with a mean Cohens Kappa of 0.70 (range, 46.5-94.4%) in the current analysis. CONCLUSION: The perioperative management of antithrombotics in intracranial procedures may be challenging, complex, and demanding. Due to the lack of high quality data, uncertainty remains regarding the optimal practices to balance the risk of thromboembolism against that of bleeding.

Background and Aims: Preliminary evidence suggests a possible relationship between type 2 diabetes mellitus (T2DM) and perioperative neurocognitive disorders (NCD). We sought to investigate whether patients with T2DM, undergoing elective noncardiac surgery under general anesthesia, are at increased risk of perioperative NCD. Material and Methods: A prospective cohort study was designed. One-hundred and forty-four patients with T2DM and 144 healthy controls were recruited. Controls were matched for sex, age, type of operation, and educational background. Postoperative delirium (POD), delayed neurocognitive recovery and postoperative NCD were evaluated. Results: Two hundred twenty-eight patients were analyzed. Compared to controls, patients with T2DM were diagnosed with higher rates of NCD preoperatively (n = 96 vs. n = 26, P < 0.05) and higher POD up to 4 days postoperatively (n = 204 vs. n = 68, P < 0.05). Increased rates of delayed neurocognitive recovery and postoperative NCD were recorded in patients with T2DM up to 9 months postoperatively (n = 473 vs. n = 192, P < 0.05). Insulin-dependent patients had higher rates of POD on the second (n = 38 vs. n = 24, P < 0.05) and third day (n = 27 vs. n = 16, P < 0.05) when compared to noninsulin-dependent patients. Logistic multivariable analysis revealed that patients with T2DM are at increased risk for postoperative cognitive disorders. Conclusion: Patients with type 2 diabetes mellitus appear to be at a higher risk of perioperative NCDs up to 9 months after elective noncardiac surgery under general anesthesia.
RESUMO
OBJECTIVE: Optimal thromboprophylaxis in orthopaedic procedures is crucial in an attempt to lower the risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism. We aim to: 1) identify clinical practice guidelines (CPGs) and recommendations (CPRs) on thromboprophylaxis in adult patients undergoing orthopaedic procedures, and 2) assess the methodological quality and reporting clarity of these guidelines. METHODS: The study was conducted following the 2020 PRISMA guidelines for a systematic review and has been registered on the international prospective register of systematic reviews (PROSPERO) under the registration number (CRD42023406988). An electronic search was conducted using Medline, Embase, Cochrane, Web of Science, Google Scholar and medRxiv. The search terms used were ""adults", "orthopedic surgery", "orthopedic surgeries", "orthopedic surgical procedure", "orthopedic surgical procedures" "english language", "venous thromboembolism", in all possible combinations (January 2013 to March 2023). The eligible studies were evaluated by four blind raters, employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool. RESULTS: The literature research resulted in 931 studies. Finally, a total of 16 sets of guidelines were included in the current analysis. There were 8 national and 8 international CPGs. Eight CPGs made specific recommendations for orthopaedic surgery and referred mostly to joints; one guideline focused on pelvi-acetabular trauma, while the rest were more inclusive and non-specific. Four guidelines, one from the American Society of Hematology (ASH), two from the United Kingdom (UK) and one from India were found to have the highest methodological quality and reporting clarity according to the AGREE-II tool. Inter-rater agreement was very good with a mean Cohens Kappa 0.962 (95 % CI, 0.895-0.986) in the current analysis. So, the reliability of the measurements can be interpreted as good to excellent. CONCLUSION: Optimal thromboprophylaxis in orthopaedic procedures is crucial. The available guidelines were found to be mostly of high methodological quality and inter-rater agreement was very good, according to our study.

Arthroscopic anterior cruciate ligament (ACL) reconstruction with hamstring grafting is a common orthopedic procedure that is associated with moderate-to-severe pain. Peripheral nerve blockade as an anesthetic technique is an appealing option in the era of modern anesthesia. The aim of this narrative review is to document the efficacy and safety of the combination of femoral, obturator, and sciatic (FOS) nerve blocks as an exclusive method for anesthesia in patients undergoing ACL reconstruction. An electronic search of the literature published up to October 2023 was conducted in the Medline, Embase, Cochrane, Web of Science, and Google Scholar databases to find studies on ACL reconstruction and peripheral obturator nerve block. Overall, 8 prospective studies-with a total of 315 patients-published between 2007 and 2022 were included in this review. Ultrasound-guided peripheral FOS nerve blockade is an effective anesthetic technique for ACL reconstruction, offering good perioperative pain management, minimal opioid consumption, and an excellent safety profile. Further well-designed prospective studies are needed to determine the best approach for obturator nerve blockade and the appropriate type and dosage of local anesthetic.
RESUMO
Background: The clinical significance of combinations of inflammatory biomarkers in severe COVID-19 infection is yet to be proved. Although several studies have evaluated the prognostic value of biomarkers in patients with COVID-19, there are limited data regarding the value of the combination scores that could take full advantage of the prognostic value of several biomarkers and that could account for the heterogeneity of patients with severe COVID-19. We investigated the prognostic value of combination scores of admission values of inflammatory biomarkers in adults with severe COVID-19. Methods: Adults admitted to the Department of Respiratory Medicine of the UHL with severe COVID-19 (April-September 2021, NCT05145751) were included. Demographics, medical history, laboratory tests and outcome (high-flow nasal cannula (HFNC), admission to Intensive Care Unit (ICU) or death) were recorded. The optimal cut-off points of on admission values of C-reactive protein (CRP), CRP to lymphocyte ratio (CLR), lymphocyte to neutrophil ratio (LNR) and derived variation of neutrophil to lymphocyte ratio (dv-NLR (neutrophil/white blood count-lymphocyte)) for the predetermined outcome were defined. Based on the cut-off of CRP, LNR, dv-NLR and CLR, which were found to be predictors for HFNC, 3 scores were defined: CRP and LNR (C-CRP #1), CRP and dv-NLR (C-CRP #2), CRP and CLR (C-CRP #3). Likewise, based on the cut-off of CRP and CLR, which were found to be predictors for death, the score of CRP and CLR (C-CRP #3*) was defined. The combination scores were then classified as: 2 points (both biomarkers elevated); 1 point (one biomarker elevated) and 0 points (normal values). None of the biomarkers was predictive for the ICU admission, so no further analysis was performed. Binomial logistic regression analysis was used to establish the predictive role for each biomarker. Results: One hundred and fifteen patients (60% males, mean age 57.7 years) were included. Thirty-seven (32.2%) patients required HFNC, nine (7.8%) died and eight (7%) were admitted to ICU, respectively. As far as HFNC is concerned, the cut-off point was 3.2 for CRP, 0.231 for LNR, 0.90 for dv-NLR and 0.004 for CLR. Two points of C-CRP #1 and 2 points of C-CRP #3 predicted HFNC with a probability as high as 0.625 (p = 0.005) and 0.561 (p < 0.001), respectively. Moreover, 1 point of C-CRP #2 and 2 points of C-CRP #2 predicted HFNC with a probability of 0.333 and 0.562, respectively. For death, the optimal cut-off point for CRP was 1.11 and for CLR 3.2*1033. Two points of C-CRP #3* with an accuracy of 0.922 predicted mortality (p = 0.0038) in severe COVID-19. Conclusions: The combination scores of CRP and inflammatory biomarkers, based on admission values, are promising predictors for respiratory support using HFNC and for mortality in patients suffering from severe COVID-19 infection.
RESUMO
INTRODUCTION: Hip fractures represent 1 of the most common injuries in older adults. They are associated with increased perioperative morbidity and mortality. Additionally, current research suggests that SARS-COV-2 infection may worsen the prognosis of the hip fracture patients who undergo hip fixation. The aims of the present study were: (1) to determine the rate of specific adverse events including VTE (venous thromboembolism) and major adverse cardiovascular events (MACEs) in patients with hip fracture and concomitant SARS-CoV-2 infection undergoing surgery; and (2) to examine if the aforementioned population is at increased risk for VTE and MACEs, when compared to SARS-CoV-2 free patients with hip fracture. METHODS: PubMed, EMBASE, Cochrane, Web of Science, Google scholar and medRxiv were searched from March 2020 to January 2021 for English language studies with patients suffering from hip fractures and SARS-COV-2 -CoV-2. 2 researchers were involved in the data extraction and the quality assessment of the studies respectively. RESULTS: The literature search yielded a total of 1256 articles of which 14 were included in the systematic review and 7 in the meta-analysis respectively. The estimated pooled rate for VTE and MACE were 4.3% and 6.3% respectively. Patients with hip fracture and concomitant SARS-CoV-2 infection who undergo surgery are at increased risk for VTE, when compared to SARS-CoV-2 free patients (odds ratio 2.8 [95% CI, 1.1-7.1]). These patients are also at increased risk for MACE postoperatively as indicated by the odds ratio 2.4 (95% CI, 1.0-5.8). The quality of the studies was moderate. CONCLUSIONS: Although there is a lack of high-quality data it seems that patients with hip fractures and concomitant SARS-CoV-2 infection are facing a 2.8 and 2.4 times increased risk for VTE and MACE.

Introduction: Primary sclerosing cholangitis sets the scene for several pathologies of both the intrahepatic and the extrahepatic biliary tree. Surgical treatment, when needed, is almost unanimously summarized in the creation of a Roux-en-Y hepaticojejunostomy, a procedure with a relatively high associated failure rate. Presentation of case: A 70-year-old male, diagnosed with primary sclerosing cholangitis, was submitted to a Roux-en-Y hepaticojejunostomy due to a dominant stricture of the extrahepatic biliary tree. Recurrent episodes of acute cholangitis dictated a workup in the direction of a possible stenosis at the level of the anastomosis. The imaging studies were inconclusive while both the endoscopic and the transhepatic approach failed to assess the status of the anastomosis. A laparotomy, with the intent to revise a high suspicion for stenosis hepaticojejunostomy, was decided. Intraoperatively, a decision to assess the hepaticojejunostomy prior to the scheduled surgical revision, via endoscopy, was made. In this direction, an enterotomy was made on the short jejunal blind loop in order to gain luminal access and an endoscope was propelled through the enterotomy towards the biliary enteric anastomosis. Results: The inspection of the anastomosis under direct endoscopic vision showed no evidences of stenosis and averted an unnecessary, under these circumstances, revision of the anastomosis. Conclusions: The surgical revision of a Roux-en-Y hepaticojejunostomy is a highly demanding operation with an increased associated morbidity, and it should be reserved as the final resort in the treatment algorithm. An approach of utilizing surgery to facilitate the endoscopic assessment prior to proceeding to the surgical revision of the anastomosis appears justified.
RESUMO
BACKGROUND: We evaluated the 30-day postoperative outcome after elective endovascular aneurysm repair (EVAR) and the possible predictors for the 30-day postoperative outcome. MATERIALS: Demographics, medical history, laboratory values, intensive care unit (ICU) admission and 30-day complications classified as major (major adverse cardiovascular events (MACEs), acute kidney injury (AKI) and death of any cause) and minor (postimplantation syndrome (PIS), postoperative delirium (POD), urinary tract infection (UTI) and technical graft failure) were documented (March 2016 to February 2019). RESULTS: We included 322 patients. The majority were managed under general anesthesia (83%) with femoral cutdown (98.1%). Overall, 121 (37.5%) complications, mostly minor (n = 103, 31.9%), were recorded. In total, 11 patients (3.4%) developed MACEs, 5 (1.6%) experienced AKI and 2 (0.6%) died in the ICU. Moreover, 77 patients (23.9%) suffered from PIS, 11 from POD, 11 from UTI and 4 from technical graft failure. The multivariate logistic regression analysis revealed that aneurysm diameter (p = 0.01) and past smoking (p = 0.003) were predictors for complications. PAD was an independent predictor of MACEs (p = 0.003), preoperative neutrophil to lymphocyte ratio (NLR) of AKI (p = 0.003) and past smoking of PIS (p = 0.008), respectively. CONCLUSIONS: Our study showed that the 30-day morbidity after EVAR exceeded 35%. However, the majority of complications were minor, and the associated mortality was low. Aneurysm diameter and past smoking were independent predictors for postoperative outcome.
RESUMO
The perioperative management of patients medicated with antithrombotic agents who require elective spinal surgery is extremely challenging because of the increased risk of surgical bleeding and the concurrent need to minimize the thromboembolic risk. The aims of the present systematic review are to: (1) identify clinical practice guidelines (CPGs) and recommendations (CPRs) on this topic and (2) assess their methodological quality and reporting clarity. An electronic systematic search of the English Medical Literature up to January 31, 2021 was conducted using PubMed, Google Scholar, and Scopus. Two raters assessed the methodological quality and reporting clarity of the gathered CPGs and CPRs using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. The agreement between the two raters was assessed using Cohen's kappa. Of the initially gathered 38 CPGs and CPRs, 16 fulfilled our eligibility criteria and were evaluated using the AGREE II instrument. The reports published by "Narouze 2018" and "Fleisher 2014" were scored as being of "high-quality" and having an adequate interrater agreement (Cohen's kappa ≥0.60). Overall, the AGREE II domains of "clarity of presentation" and "scope and purpose" yielded the highest scores (100%), whereas the domain "stakeholder involvement" scored the lowest score (48.5%). The perioperative management of antiplatelet and anticoagulant agents in elective spine surgery may be challenging. Because of the lack of high-quality data in this field, uncertainty remains regarding the optimal practices to balance the risk of thromboembolism against that of bleeding.
RESUMO
COVID-19 pandemic resulted in an unprecedented crisis with extreme distress for the frontline physicians and increased risk of developing burnout. Burnout has a negative impact on patients and physicians, posing a substantial risk in patient safety, quality of care and physicians' overall wellbeing. We evaluated burnout prevalence and possible predisposing factors among anaesthesiologists in the COVID-19 referral university/tertiary hospitals in Greece. In this multicenter, cross-sectional study we have included anaesthesiologists, involved in the care of patients with COVID-19, during the fourth peak of the pandemic (11/2021), in the 7 referral hospitals in Greece. The validated Maslach Burnout Inventory (MBI) and Eysenck Personality Questionnaire (EPQ) were used. The response rate was 98% (116/118). More than half of the respondents were females (67.83%, median age 46 years). The overall Cronbach's alpha for MBI and EPQ was 0.894 and 0.877, respectively. The majority (67.24%) of anaesthesiologists were assessed as "high risk for burnout" and 21.55% were diagnosed with burnout syndrome. Almost half participants experienced high levels of all three dimensions of burnout; high emotional exhaustion (46.09%), high depersonalization (49.57%) and high levels of low personal accomplishment (43.49%). Multivariate logistic analysis revealed that neuroticism was an independent factor predicting "high risk for burnout" as well as burnout syndrome, whereas the "Lie scale" of EPQ exhibited a protective effect against burnout. Burnout prevalence in Greek anaesthesiologists working in COVID-19 referral hospitals during the fourth peak of the pandemic was high. Neuroticism was predictive of both "high risk for burnout" and "burnout syndrome".
RESUMO
CASE: An elderly, polytrauma patient receiving vitamin K antagonist (VKA) for atrial fibrillation required immediate surgery for open distal tibial fracture. As the initial reversal with vitamin K and fresh frozen plasma by the trauma team was ineffective, the "Bleeding Team" was convened and administrated the appropriate four-factor prothrombin complex regimen, reversing the VKA in a timely manner. Surgery was performed under peripheral nerve blockade subsequently. The postoperative course of the patient was uneventful. CONCLUSION: The individualized approach and the multidisciplinary experts' team guidance is of outmost importance in patients who are treated with anticoagulants and present for nonelective surgery.

OBJECTIVE: In recent years, there has been a growing interest regarding the implementation of multimodal analgesia as an important component of the ideal perioperative patient management. The aim of the current umbrella review was to establish the role of multimodal analgesia in patients undergoing spine surgery during the immediate postoperative period. METHODS: A systematic review of the pertinent literature was performed. The evaluation was based on a multitude of primary endpoints including the postoperative requirements for patient-controlled analgesia, pain intensity, back-related disability, overall functionality, patient satisfaction, complications, length of hospitalization, and costs. RESULTS: The results were summarized using a meta-analysis in the presence of quantitative data or in a narrative review, otherwise. There was a large body of high-quality evidence supporting that the implementation of multimodal analgesia improves patient outcome in terms of the intensity of postoperative pain, the requirements for postoperative opioid analgesia, and the opioid-associated side effects. Similarly, limited high-quality evidence supported that multimodal analgesia improved patients' functionality and satisfaction while decreasing the length of hospitalization and overall costs of surgery. However, the results were inconclusive as far as the disability was concerned. CONCLUSIONS: Multimodal analgesia seems to have an essential role for the optimal management of patients undergoing spine surgery. Future research is required to optimize the multimodal analgesia protocols in this group of patients.

The association of chronic inflammatory markers with the clinical outcome after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) was investigated. We included 230 patients, treated electively with EVAR. The values of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were measured pre- and postoperatively. Any major adverse cardiovascular event (MACE) and acute kidney injury (AKI) were recorded. Adverse events occurred in 12 patients (5.2%). Seven patients suffered from MACE and five from AKI. Median NLR and PLR values were significantly increased after the procedure (NLR: from 3.34 to 8.64, p < 0.001 and PLR: from 11.37 to 17.21, p < 0.001). None of the patients or procedure characteristics were associated with the occurrence of either a MACE or AKI. Receiver operating characteristic curve analysis showed that postoperative NLR and PLR were strongly associated with AKI. A threshold postoperative NLR value of 9.9 was associated with the occurrence of AKI, with a sensitivity of 80% and specificity of 81%. A threshold postoperative PLR value of 22.8 was associated with the occurrence of AKI, with a sensitivity of 80% and specificity of 83%. Postoperative NLR and PLR have been associated with the occurrence of AKI after EVAR for AAA.
