Perioperative management of pheocromocytoma/paraganglioma: a comprehensive review / Manejo perioperatorio del feocromocitoma/ paraganglioma: una revisión exhaustiva

Abstract Pheochromocytomas are rare neuroendocrine neoplasms that require adequate preoperative evaluation in order to prevent and lessen the serious complications of catecholamine hypersecretion. Preoperative management contributes to reducing morbidity and mortality rates in patients who have not been diagnosed with this condition and undergo any surgery. However, current mortality seems to be lower, a fact attributed to preoperative management with alpha blockers.

Resumen Los feocromocitomas son neoplasias neuroendocrinas poco frecuentes que requieren una evaluación preoperatoria adecuada, con el fin de prevenir y disminuir las complicaciones graves de la hipersecreción de catecolaminas. El manejo preoperatorio contribuye a disminuir las tasas de morbimortalidad en los pacientes que no han sido diagnosticados con esta entidad y son sometidos a cualquier cirugía. Sin embargo, la mortalidad actual parece ser más baja, hecho atribuido a un manejo preoperatorio con α-bloqueadores.

Os cirurgiões e a pandemia do COVID-19 / The surgeons and the COVID-19 pandemic

RESUMO A atual pandemia do novo coronavírus, Covid-19, tem sido o assunto mais discutido no momento, tanto na mídia como em periódicos científicos. O medo, a incerteza e o desconhecimento sobre o comportamento da doença são os fatores preponderantes que podem justificar essa realidade. Sabe-se de antemão que a enfermidade tem grande disseminação, é mais grave entre idosos e está associada a grande impacto socioeconômico mundial. Além dos desafios em lidar com o desconhecido, há outros relacionados com a sobrecarga de informação e nesse quesito, a grande quantidade de estudos científicos, que englobam pesquisas in vitro, relatos de casos, estudos observacionais e randomizados, além de revisões sistemáticas complementam o panorama de dúvidas. Essa situação é piorada porque o conhecimento sobre o método científico não é dominado pela maioria dos profissionais de saúde, algo que há muito já vem sendo divulgado por vários autores. De sorte que em função desta realidade, torna-se fundamental que sociedades de especialidades apoiadas por dados da Organização Mundial da Saúde e do Ministério da Saúde assumam a liderança da divulgação da informação correta e confiável. O Colégio Brasileiro de Cirurgiões sugere neste documento medidas que podem auxiliar cirurgiões e outros profissionais de saúde, assim como pacientes, em caso de necessidade cirúrgica, a lidar com a atual pandemia.

ABSTRACT The current world Covid-19 pandemic has been the most discussed topic in the media and scientific journals. Fear, uncertainty, and lack of knowledge about the disease may be the significant factors that justify such reality. It has been known that the disease presents with a rapidly spreading, it is significantly more severe among the elderly, and it has a substantial global socioeconomic impact. Besides the challenges associated with the unknown, there are other factors, such as the deluge of information. In this regard, the high number of scientific publications, encompassing in vitro, case studies, observational and randomized clinical studies, and even systematic reviews add up to the uncertainty. Such a situation is even worse when considering that most healthcare professionals lack adequate knowledge to critically appraise the scientific method, something that has been previously addressed by some authors. Therefore, it is of utmost importance that expert societies supported by data provided by the World Health Organization and the National Health Department take the lead in spreading trustworthy and reliable information. The Brazilian College of Surgeons suggests in this document various initiatives that may help surgeons, healthcare providers, and patients who will have to face a surgical event under the pandemic.

Adverse Events and Risk Factors of Blood Transfusion in Cardiovascular Surgery: A Prospective Cohort Study

Abstract Background: Hemodilution, transoperative bleeding and cardiopulmonary bypass (CPB) are some of the factors associated with high transfusion rates in cardiac surgery. Objective: To analyze the incidence of blood transfusion and early postoperative outcomes in cardiac surgery patients. Methods: Cohort study of patients undergoing cardiac surgery in a university hospital, consecutively enrolled from May 2015 to February 2017. Data were prospectively collected and comparisons were made between two patients' groups: transfused and not transfused. Student's t-test, chi-square test, and logistic regression were used, and a p-value < 0.05 was considered significant. Results: Among the 271 patients evaluated, 100 (37%) required transfusion in the transoperative (32.1%) and/or postoperative periods (19.5%). The following predictors of transfusion were identified by multivariate analysis: EuroScore II (OR 1.2); chronic kidney disease (CKD) (OR 3.2); transoperative bleeding ≥ 500 mL (OR 6.7); baseline hemoglobin (Hb) ≤ 10 g/dL (OR 11.5); activated partial thromboplastin time (aPTT) (OR 1.1) and CPB duration (OR 1.03). Transfusion was associated with prolonged mechanical ventilation (≥ 24h) (2.4% vs. 23%), delirium (5.9% vs. 18%), bronchopneumonia (1.2% vs. 16%), acute renal failure (3.5% vs. 25%), acute on CKD (0.6% vs. 8%), stroke or transient ischemic attack (1.8% vs. 8%), intensive care unit stay ≥ 72 h (36% vs. 57%), longer hospital stay (8 ± 4 days vs. 16 ± 15 days), as well as increased early mortality (1.75% vs. 15%). Conclusion: EuroScore II, CKD, major transoperative bleeding, preoperative Hb and aPTT values and CPB time were independent predictors of transfusion, which was associated with a higher rate of adverse outcomes, including early mortality.

Intraoperative vancomycin powder and post-operative infection after spinal surgery: a systematic review and meta-analysis

SUMMARY

Anesthetic considerations for lung transplantation

Since the first lung transplantation, developments in surgical techniques, immunosuppressants, preservation solutions, monitoring devices, anesthetic agents, and drugs and devices for hemodynamic support have resulted in improved survival rates after lung transplantation. Lung transplantation is a high-risk procedure and end-stage lung disease is frequently accompanied by compromised cardiopulmonary function. Therefore, a highly trained cardiothoracic anesthesiologist is required during the procedure. As various factors related to anesthesia may have important effects on the prognosis of the patient after the lung transplantation, an anesthesiologist must not only be familiar with the use of various medications and monitoring devices, but also understand the patient's pathophysiology and the surgical procedure.

Factors Associated with Inadequate Management of Antiplatelet Agents in Perioperative Period of Non-Cardiac Surgeries / Fatores Associados com o Manejo Inadequado de Antiagregantes Plaquetários em Perioperatório de Cirurgias não Cardíacas

Abstract Background: The current guidelines dispose recommendations to manage antiplatelet agents in the perioperative period; however, the daily medical practices lack standardization. Objectives: To asses factors associated with inadequate management of antiplatelet agents in the perioperative period of non-cardiac surgeries. Methods: Cross-sectional Study conducted in hospital from October 2014 to October 2016. The study dependent variable was a therapy that did not comply with the recommendations in the Brazilian Association of Cardiology (SBC) guidelines. The independent variables included some characteristics, the people in charge of the management and causes of lack of adherence to those guidelines. Variables were included in the multivariate model. Analysis was based on the odds ratio (OR) value and its respective 95% confidence interval (CI) estimated by means of logistic regression with 5% significance level. Results: The sample was composed of adult patients submitted to non-cardiac surgeries and who would use acetylsalicylic acid (aspirin) or clopidogrel (n = 161). The management failed to comply with the recommendations in the guidelines in 80.75% of the sample. Surgeons had the highest number of noncomplying orientations (n = 63). After multivariate analysis it was observed that patients with a higher level of schooling (OR = 0.24; CI95% 0.07-0.78) and those with a previous episode of acute myocardial infarction (AMI) (OR = 0.18; CI95% 0.04-0.95) had a higher probability of using a therapy complying with the guidelines. Conclusion: Positive association between patients' schooling level, or those with a history of previous AMI, with management of the use of aspirin and clopidogrel in the perioperative period of non-cardiac surgeries. However, diverging conducts stress the need of having internal protocol defined.

Resumo Fundamento: As diretrizes atuais apresentam recomendações para o manejo de antiagregantes plaquetários em perioperatório, entretanto, na prática clínica diária há falta de padronização das condutas médicas. Objetivos: Avaliar os fatores associados ao manejo inadequado de antiagregantes plaquetários em perioperatório de cirurgias não cardíacas. Métodos: Estudo transversal, realizado de outubro de 2014 a outubro de 2016, em hospital. A variável dependente do estudo foi a terapia divergente das recomendações das diretrizes da Sociedade Brasileira de Cardiologia (SBC). As variáveis independentes incluíram algumas características, os responsáveis pelo manejo e as causas de não adesão às diretrizes. As variáveis foram incluídas no modelo multivariado. A análise se baseou no valor de oddsratio (OR) e seu respectivo intervalo de confiança (IC) de 95%, estimados por regressão logística com um nível de significância de 5%. Resultados: A amostra foi composta de pacientes adultos submetidos a cirurgias não cardíacas e que faziam uso de ácido acetilsalicílico (AAS) ou clopidogrel (n = 161). O manejo esteve em desacordo com aquele preconizado pelas diretrizes em 80,75% da amostra. Os cirurgiões realizaram o maior número (n = 63) de orientações em desacordo. Após a análise multivariada, observou-se que os pacientes com nível de escolaridade superior (OR = 0,24; IC95% 0,07-0,78) e aqueles com episódio prévio de infarto agudo do miocárdio (IAM) (OR = 0,18; IC95% 0,04-0,95) possuem maior chance de utilizar a terapia em concordância com as recomendações. Conclusão: Associação positiva entre o nível de escolaridade dos pacientes ou histórico prévio de IAM com o manejo do uso de AAS e clopidogrel em perioperatório de cirurgias não cardíacas. Porém as divergências nas condutas reforçam a necessidade de definição de protocolos internos.

Objective To investigate the nursing of sedation and analgesia using low-dose fentanyl with midazolam during intra-arterial treatment with mechanical thrombectomy by means of stent for patients with anterior-circulation acute ischemic stroke.Methods All of 61 patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke were retrospectively collected.They were divided into two groups according to the different program of individual conscious sedation:the control group(30 cases)used midazolam for intravenous maintain sedation,experimental group(31 cases)added the low-dose fentanyl on the basis of the control group.The thrombectomy was performed by the same group of interventional radiologists,while the effect of sedative,vital signs,respiratory curve and SpO2(blood oxygen saturation),assessment of Ramsay's sedation score,restlessness and other sedation adverse reactions were respectively observed in both groups.Nursing intervention was performed aiming at different states of patients during operation.Results All 61 patients were implemented with good medical care with no intracranial hemorrhage or intraoperative death.In the control group,there were 4 patients with Ramsay 1 point of sedation,resulted motion artifacts in digital subtraction angiography images in 3 of them,1 patient with slight reduction of SpO2,and vomiting in 4 patients.1 patient with decreased mean arterial pressure.In the experimental group,there was no Ramsay 1 point of sedative patient.The SpO2 was decreased in 5 patients.Respiratory inhibition occurred in 3 patients and the mean arterial pressure decreased slightly in the other 3 patients.Conclusions Application of low-dose fentanyl and midazolam is safe and reliable in patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke.While closely observation to the changes of breath frequency curve and SpO2 in operation are very essential to actively prevent the occurrence of respiratory depression.

Cuidados perioperatórios em cirurgia bariátrica no contexto do projeto ACERTO: realidade e o imaginário de cirurgiões em um hospital de Cuiabá / Perioperative care in bariatric surgery in the context of the ACERTO project: reality versus surgeons assumptions in a Cuiabá hospital

RESUMO Objetivo: verificar o grau de conhecimento entre cirurgiões, sobre as recomendações do Projeto ACERTO em cirurgia bariátrica, correlacionando o "imaginário", sobre suas prescrições, e a "realidade", através de dados de prontuários de seus pacientes. Métodos: estudo observacional longitudinal prospectivo comparativo entre o "imaginário" dos cirurgiões, obtido através de respostas de questionário sobre condutas recomendadas pelo ACERTO e a análise de dados clínicos "reais" encontrados em prontuários de pacientes submetidos à cirurgia bariátrica. Foram analisados: jejum pré-operatório, realimentação precoce, hidratação venosa perioperatória, antibioticoprofilaxia, uso de sondas e drenos, analgesia e profilaxia de náuseas e vômitos. Foram confrontadas as respostas de sete cirurgiões e dados de 200 prontuários médicos. Resultados: todos os cirurgiões entrevistados conheciam o Projeto ACERTO. Cinco (72%) responderam que seguiam o protocolo completamente. O tempo mediano de jejum pré-operatório foi maior do que o relatado pelos cirurgiões (p<0,05). Os pacientes receberam realimentação precoce em 96,5% dos casos. O volume mediano de fluidos prescritos nas primeiras 24 horas foi 4000ml, condizente com a entrevista. Em relação à antibioticoprofilaxia, uso de sondas e drenos, analgesia e prevenção de náuseas e vômitos, não houve diferença entre o respondido e o constatado nos prontuários. Conclusão: o Projeto ACERTO era bem praticado entre os cirurgiões pesquisados, havendo boa correlação entre o "imaginário" e "realidade" dos cuidados perioperatórios prescritos em pacientes submetidos à cirurgia bariátrica.

ABSTRACT Objective: to assess the level of knowledge among bariatric surgeons, about the recommendations of the ACERTO Project, correlating their assumptions on their perioperative prescriptions and the reality, according to the patients charts. Method: we conducted a prospective, longitudinal, observational study comparing the assumptions of bariatric surgeons obtained through responses on a specific questionnaire with the reality found in clinical data from the hospital records. We analyzed the following variables: preoperative fasting, early postoperative feeding, intravenous hydration, perioperative antibiotic prophylaxis, use of abdominal drains, type of analgesia, and prophylaxis of nausea and vomiting. We confronted the responses of seven surgeons with data from 200 records of patients undergoing gastroplasty for morbid obesity. Results: all interviewed surgeons knew the ACERTO Project. Five (72%) responded that they followed the protocol thoroughly. The median time of preoperative fasting found in the records was higher than the reported by the surgeons (p<0.05). Early postoperative feeding was prescribed for 96.5% of cases. The median volume of intravenous fluids prescribed in the first 24 hours was 4000ml, which was consistent with the interviews. There were no differences between the response in the questionnaire and the findings in the hospital records in relation to antibiotic prophylaxis, use of catheters and drains, analgesia and prophylaxis of nausea and vomiting. Conclusion: the ACERTO Project was well practiced among the surveyed surgeons. There was a good correlation between their assumptions and the reality in perioperative care of patients undergoing bariatric surgery. However, there was a significant difference in preoperative fasting time.

The effect of different temperature setting of forced- air warming system on the prevention of hypothermia during laparotomy of infants / 中国实用护理杂志

Objective To explore the effect of different temperature of the forced- air warming system on the prevention of hypothermia during laparotomy of infants. Methods A total of 60 infants undergoing laparotomy under general anesthesia were recruited and divided into three groups by random digits table method with 20 cases each according to admitting time; when used the force- air warming system intraoperatively, the three groups were respectively setting on 45℃(automatic adjustment for 43 ℃ after 45 minutes), 43 ℃ and 38 ℃.The core temperature were respectively recorded before anesthesia and 15, 30, 45, 60 minutes after anesthesia (every 30 minutes after 1 hour).The hypothermia incidence and anesthesia recovery conditions were recorded simultaneously. Results There was no significant difference on the core temperature among three groups before anesthesia (P > 0.05). 30 minutes after the anesthetic, the core temperature of 45 ℃ group was (36.31±0.20) ℃,43 ℃ group was (36.32±0.24) ℃ and 38 ℃ group was (36.08±0.21) ℃.The differences among three groups was statistically significant (F=8.12, P 0.05). 60 minutes after the anesthetic, the core temperature of 45 ℃ group was (36.39±0.26) ℃,43 ℃ group was (36.19±0.22) ℃ and 38 ℃ group was (35.92±0.15) ℃. The differences among three groups was statistically significant(F=25.19, P<0.01).The hypothermia incidence of 45℃group, 43℃ group,38℃ group was 10.0%(2/20), 25.0%(5/20), 50.0%(10/20)respectively and the differences among three groups was statistically significant( χ2=8.04, P<0.05). The time to complete consciousness of 45 ℃ group was (15.40±5.09) minutes,43 ℃ group was (19.80±4.10) minutes and 38 ℃ group was (22.00±4.36) minutes. The differences among three groups was statistically significant (F=10.96, P<0.01). The time to tracheal extubation of 45 ℃ group was (18.10±5.97) minutes, 43 ℃ group was (21.85±4.02) minutes and 38 ℃ group was (24.90±5.54) minutes.The differences among three groups was statistically significant (F=9.83, P<0.01). Conclusions The forced-air warming system can increase the infants′peripheral tissue heat content and reduce the heat losing.So that it will help decrease the intraoperative hypothermia incidence and shorten the anesthesia recovery period.Meanwhile the higher temperature of the forced-air warming system is setted ,the better effect it is.

Characterization of hip and knee arthroplasties and factors associated with infection / Caracterização de artroplastias de quadril e joelho e fatores associados à infecção

To characterize arthroplasty procedures, calculate the surgical infection rate and identify related risk factors. METHODS: This was a retrospective cohort study. Data on operations performed between 2010 and 2012 were gathered from documental sources and were analyzed with the aid of statistical software, using Fisher's exact test, Student'sttest and the nonparametric Mann-Whitney and Wilcoxon tests. RESULTS: 421 total arthroplasty procedures performed on 346 patients were analyzed, of which 208 were on the knee and 213 on the hip. It was found that 18 patients (4.3%) were infected. Among these, 15 (83.33%) were reoperated and 2 (15.74%) died. The prevalence of infection in primary total hip arthroplasty procedures was 3%; in primary total knee arthroplasty, 6.14%; and in revision of total knee arthroplasty, 3.45%. Staphylococcus aureuswas prevalent. The length of the surgical procedure showed a tendency toward being a risk factor ( p= 0.067). CONCLUSION: The prevalence of infection in cases of primary total knee arthroplasty was greater than in other cases. No statistically significant risk factors for infection were identified.

O tempo de duração da cirurgia indicou uma tendência como fator de risco (p = 0,067). CONCLUSÃO: A prevalência de infecção em artroplastia total de joelho primária foi superior às demais e não foram identificados fatores de risco para infecção com significância estatística.

The role of intraoperative ultrasonography in the diagnosis and management of focal hepatic lesions

Intraoperative ultrasonography (IOUS) has been widely utilized in hepatic surgery both as a diagnostic technique and in the course of treatment. Since IOUS involves direct-contact imaging of the target organ, it can provide high spatial resolution without interference from the surrounding structures. Therefore, IOUS may improve the detection, characterization, localization, and local staging of hepatic tumors. IOUS is also a real-time imaging modality capable of providing interactive information and valuable guidance in a range of procedures. Recently, contrast-enhanced IOUS, IOUS elastography, and IOUS-guided hepatic surgery have attracted increasing interest and are expected to lead to the broader implementation of IOUS. Herein, we review the various applications of IOUS in the diagnosis and management of focal hepatic lesions.

Outcomes of cataract surgery in diabetic patients: results of the Pan American Collaborative Retina Study Group / Resultados da cirurgia de catarata em pacientes diabéticos: resultados do Pan-American Collaborative Retina Study Group

Purpose: This study was designed to evaluate the visual and anatomical outcomes after cataract surgery in diabetic patients with different intraoperative therapeutic strategies. Methods: The research design comprised of a multicentric, retrospective, interventional study conducted at 6 centers in Argentina, Brazil, Costa Rica, Puerto Rico, Spain, and Venezuela. We included 138 diabetic patients with at least 6-month follow-up following phacoemulsification and intraocular lens implantation. Best-corrected visual acuity (BCVA) and central subfield thickness were collected at baseline and at 1-, 2-, 3-, and 6-month follow-up. Of these, 42 cases were not treated with any intraoperative coadjuvant medication (Group 1), 59 patients received intraoperative bevacizumab (Group 2) and 37 patients received intraoperative triamcinolone (4 mg/0.1 ml) (Group 3). Results: The mean logMAR [± standard deviation (SD)] BCVA improved from 0.82 (± 0.43) at baseline, to 0.14 (± 0.23) at 6-month follow-up (p<0.001) in Group 1; from 0.80 (± 0.48) to 0.54 (± 0.45) (p<0.001) in Group 2; and from 1.0 (± 0.40) to 0.46 (± 0.34) (p<0.001) in Group 3. The mean central subfield thickness increased from 263.57 µm (± 35.7) at baseline to 274.57 µm (± 48.7) at 6-month follow-up (p=0.088) in Group 1; from 316.02 µm (± 100.4) to 339.56 µm (± 145.3) (p=0.184) in Group 2; and from 259.18 µm (± 97.9) to 282.21 µm (± 87.24) (p=0.044) in Group 3. Conclusion: Diabetic patients may significantly benefit from cataract surgery. This study provides evidence to support the use of intravitreal triamcinolone or bevacizumab at the time of cataract surgery in cases with pre-existent diabetic macular edema or moderate-severe non-proliferative diabetic retinopathy. .

Objetivo: Avaliar os resultados visuais e anatômicos após a cirurgia de catarata em pacientes diabéticos com estratégias terapêuticas intraoperatórias diferentes. Métodos: Estudo multicêntrico, retrospectivo, de intervenção realizado em 6 centros da Argentina, Brasil, Costa Rica, Porto Rico, Espanha e Venezuela. Foram incluídos 138 pacientes diabéticos com pelo menos 6 meses de seguimento após facoemulsificação com implante de lente intraocular. Acuidade visual melhor corrigida (BCVA) e a espessura subcampo central (CST ) foram coletadas no início e em 1, 2, 3 e 6 meses de seguimento. Destes, 42 casos não foram tratadas com qualquer co-adjuvante de medicamentos intra-operatório (Grupo 1), 59 pacientes receberam bevacizumab intraoperatório (Grupo 2), e 37 pacientes receberam triancinolona intraoperatória (4 mg/0,1 ml) (Grupo 3). Resultados: A média logMAR (± desvio-padrão [DP]) BCVA melhorou de 0,82 (± 0,43) no início do estudo, para 0,14 (± 0,23) aos 6 meses de seguimento (p<0,001) no Grupo 1; de 0,80 (± 0,48) para 0,54 (± 0,45) (p<0,001) no Grupo 2; e de 1,0 (± 0,40) para 0,46 (± 0,34) (p<0,001) no Grupo 3. A CST média aumentou de 263,57 µm (± 35,7) na linha de base para 274,57±48,7 µm em 6 meses acompanhamento (p=0,088) no Grupo 1; de 316,02 µm (± 100,4), para 339,56 µm (± 145,3) (p=0,184) no Grupo 2; e de 259,18 µm (± 97,9), para 282,21 µm (±87,24) (p=0,044) no grupo 3. Conclusões: Pacientes diabéticos podem se beneficiar significativamente da cirurgia de catarata. Este estudo parece fornecer evidências para apoiar o uso de triancinolona intravítrea ou bevacizumab no momento da cirurgia de catarata em casos com edema macular diabético preexistente (DME) ou retinopatia diabética não-proliferativa moderada a grave. .

O Concentrado de Complexo Protrombínico e suas aplicações na sala de cirurgia / Prothrombin Complex Concentrate and its applications in the operating room

Os concentrados de complexo protrombínico (CCPs) contêm fatores de coagulação dependentes da vitamina K em uma concentração 25 vezes maior que a do plasma e são classificados em compostos de três ou quatro fatores, de acordo com a presença do fator VII (FVII). Quando comparados ao plasma fresco congelado (PFC), são mais eficazes, podendo ser administrados rapidamente e com baixa dose para atingir o efeito desejado. O perfil de segurança dos CCPs ainda é incerto, já que eventos adversos, principalmente tromboembólicos, foram relatados com o seu uso. Os CCPs foram desenvolvidos, inicialmente, para o tratamento da hemofilia B. Hoje, sua indicação principal é a reversão emergencialda anticoagulação induzida por antagonistas da vitamina K. Após a criação dos concentrados de fatores específicos, os CCPs têm sido utilizados em hemofílicos, na sua forma ativada, para profilaxia de sangramento no peroperatório de pacientes portadores de anticorpos inibidores. Diversos trabalhos demonstram bons resultados com o uso de CCPs na coagulopatia dilucional induzida pelo trauma e cirurgia cardíaca. Redução do sangramento e diminuição da necessidade de hemotransfusão foram verificadas quando administrados em associação ao concentrado de fibrinogênio, porém estudos de maior impacto ainda são necessários para comprovar tais benefícios. Novos anticoagulantes orais (NACs) foram introduzidos como substitutos de cumarínicos. Mesmo com mais previsibilidade, estes não possuem antídotos conhecidos. Os CCPs ainda não são indicados de rotina no peroperatório de usuários de NACs, exceto em casos de sangramento importante ou em órgãos críticos. Em hepatopatas, CCPs são promissores, porém poucos trabalhos avaliam sua segurança e eficácia nesse perfil de paciente.

Prothrombin Complex Concentrates (PCCs) contain clotting factors that are vitamin K-dependent at a concentration 25 times greater than the plasma and are classified into compounds of three or four factors according to the presence of factor VII (FVII). When compared to frozen fresh plasma(FFPs), those are more effective, and can be administered quickly and at low doses to achieve the desired effect. The safety profile of PCCs is still uncertain because its adverse events, especially thromboembolic ones, have been reported with its use. PCCs were developed initially for thetreatment of hemophilia B. Today, its main indication is the emergency reversal of anticoagulation induced by vitamin K antagonists. After the creation of specific concentrate factors, PCCs have been used in hemophiliacs, in its activated form, for the prophylaxis of bleeding in the peri-operative period of patients who are carriers of antibody inhibitors. Several studies demonstrate good results with the use of PCCs in dilutional coagulopathy induced by trauma and cardiac surgery. Reduced bleeding and decreased need for blood transfusions were observed when administered in association with fibrinogen concentrate; however, high-impact studies are still needed to prove such benefits. New oral anticoagulants (NACs) were introduced as coumarin replacements, which even with more predictability there are no known antidotes. The PCCs are still not routinely indicated in the per-operative period for NACs users,except in cases of major bleeding or in critical organs. PCCs are promising options for patients with liver disease; however, few studies assess its safety and efficacy in these patients.
