Lactate and base deficit are predictors of mortality in critically ill patients with cancer

Cancer patients frequently require admission to intensive care unit. However, there are a few data regarding predictive factors for mortality in this group of patients. The aim of this study was to evaluate whether arterial lactate or standard base deficit on admission and after 24 hours can predict mortality for patients with cancer.Journal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Blood transfusion in cardiac surgery is a risk factor for increased hospital length of stay in adult patients

Abstract\ud \ud \ud \ud Background\ud \ud Allogeneic red blood cell (RBC) transfusion has been proposed as a negative indicator of quality in cardiac surgery. Hospital length of stay (LOS) may be a surrogate of poor outcome in transfused patients.\ud \ud \ud \ud Methods\ud \ud Data from 502 patients included in Transfusion Requirements After Cardiac Surgery (TRACS) study were analyzed to assess the relationship between RBC transfusion and hospital LOS in patients undergoing cardiac surgery and enrolled in the TRACS study.\ud \ud \ud \ud Results\ud \ud According to the status of RBC transfusion, patients were categorized into the following three groups: 1) 199 patients (40%) who did not receive RBC, 2) 241 patients (48%) who received 3 RBC units or fewer (low transfusion requirement group), and 3) 62 patients (12%) who received more than 3 RBC units (high transfusion requirement group). In a multivariable Cox proportional hazards model, the following factors were predictive of a prolonged hospital length of stay: age higher than 65 years, EuroSCORE, valvular surgery, combined procedure, LVEF lower than 40% and RBC transfusion of > 3 units.\ud \ud \ud \ud Conclusion\ud \ud RBC transfusion is an independent risk factor for increased LOS in patients undergoing cardiac surgery. This finding highlights the adequacy of a restrictive transfusion therapy in patients undergoing cardiac surgery.\ud \ud \ud \ud Trial registration\ud \ud Clinicaltrials.gov identifier: http://NCT01021631.The authors would like to thank Suelly Zeferino and Lígia Camara for their assistance with data extraction.

Post-intervention Status in Patients With Refractory Myasthenia Gravis Treated With Eculizumab During REGAIN and Its Open-Label Extension

OBJECTIVE: To evaluate whether eculizumab helps patients with anti-acetylcholine receptor-positive (AChR+) refractory generalized myasthenia gravis (gMG) achieve the Myasthenia Gravis Foundation of America (MGFA) post-intervention status of minimal manifestations (MM), we assessed patients' status throughout REGAIN (Safety and Efficacy of Eculizumab in AChR+ Refractory Generalized Myasthenia Gravis) and its open-label extension. METHODS: Patients who completed the REGAIN randomized controlled trial and continued into the open-label extension were included in this tertiary endpoint analysis. Patients were assessed for the MGFA post-intervention status of improved, unchanged, worse, MM, and pharmacologic remission at defined time points during REGAIN and through week 130 of the open-label study. RESULTS: A total of 117 patients completed REGAIN and continued into the open-label study (eculizumab/eculizumab: 56; placebo/eculizumab: 61). At week 26 of REGAIN, more eculizumab-treated patients than placebo-treated patients achieved a status of improved (60.7% vs 41.7%) or MM (25.0% vs 13.3%; common OR: 2.3; 95% CI: 1.1-4.5). After 130 weeks of eculizumab treatment, 88.0% of patients achieved improved status and 57.3% of patients achieved MM status. The safety profile of eculizumab was consistent with its known profile and no new safety signals were detected. CONCLUSION: Eculizumab led to rapid and sustained achievement of MM in patients with AChR+ refractory gMG. These findings support the use of eculizumab in this previously difficult-to-treat patient population. CLINICALTRIALSGOV IDENTIFIER: REGAIN, NCT01997229; REGAIN open-label extension, NCT02301624. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that, after 26 weeks of eculizumab treatment, 25.0% of adults with AChR+ refractory gMG achieved MM, compared with 13.3% who received placebo

Bronchial Injury and Pneumothorax after Reintubation using an Airway Exchange Catheter

Background and objectives: : We report a case of pneumothorax caused by a bronchial perforation during a reintubation using an airway exchange catheter (AEC) in a patient with a head and neck cancer. Case report: : A 53 year old man with oropharynx carcinoma was admitted to ICU for severe pneumonia and severe acute respiratory distress syndrome (ARDS). The patient was recognized as a difficult-to-intubate patient and an endotracheal tube (ETT) was inserted through a bronchoscope. After one week of treatment, it was observed an endotracheal cuff perforation. Exchanging the endotracheal tube was necessary to achieve satisfactory pulmonary ventilation. An AEC Cook 14 was used to perform the reintubation. After reintubation, the patient presented a worsening in oxygen saturation and a chest radiography (CXR) revealed a large pneumothorax. A chest tube was inserted and we observed immediate improvement in oxygen saturation. A repeat CXR confirmed correct positioning of the chest tube and reexpansion of the right lung. A bronchoscopy performed showed a posterior laceration in the right main bronchus. The patient was extubated the following day. After four days, the chest tube was removed. A CXR performed a day after chest tube removal revealed a small right upper pneumothorax, but the patient remained asymptomatic. Conclusions: : Airway exchange catheter is a valuable tool to handle with difficult-to-intubate patients. Although the physicians generally focus their attention in avoid barotrauma - caused by oxygen supplement or jet ventilation through AEC - concern for insertion technique can minimize life threatening complications and increase the safety of AEC.

Lesão brônquica e pneumotórax após reintubação usando um cateter para troca da via aérea

JUSTIFICATIVA E OBJETIVOS: Relatamos um caso de pneumotórax causado por perfuração brônquica durante uma reintubação usando um cateter para troca da via aérea (CTVA) em um paciente com câncer de cabeça e pescoço. RELATO DE CASO: Paciente do sexo masculino, 53 anos, com carcinoma de orofaringe, foi internado na UTI com pneumonia grave e síndrome da angústia respiratória aguda (SARA). O paciente foi identificado como sendo de difícil intubação e uma sonda endotraqueal (SET) foi inserida através de um broncoscópio. Após uma semana de tratamento, observou-se ruptura do manguito endotraqueal. A troca da sonda endotraqueal foi necessária para obter uma ventilação pulmonar satisfatória. Um cateter para troca da via aérea (Cook, tamanho 14) foi usado para realizar a reintubação. Depois da reintubação, o paciente apresentou piora na saturação de oxigênio e uma radiografia revelou um grande pneumotórax. Um dreno torácico foi inserido e uma melhora imediata na saturação de oxigênio foi observada. A repetição da radiografia confirmou o posicionamento correto do dreno torácico e a reexpansão do pulmão direito. A broncoscopia realizada mostrou uma laceração posterior do brônquio principal direito. O paciente foi extubado no dia seguinte. Depois de quatro dias, o dreno torácico foi removido. A radiografia realizada um dia depois da retirada do dreno revelou um pequeno pneumotórax no lobo superior direito, mas o paciente permaneceu assintomático. CONCLUSÕES: O cateter para troca da via aérea é uma ferramenta valiosa para lidar com pacientes difíceis de intubar. Embora os médicos geralmente concentrem sua atenção em evitar um barotrauma causado pelo suplemento de oxigênio ou ventilação a jato através do CTVA, a preocupação com a técnica de inserção pode minimizar as complicações que ameaçam a vida e aumentar a segurança do CTVA
