RESUMO

BACKGROUND: For practical and protective ventilation during cardiopulmonary resuscitation (CPR), a 150-grams mechanical ventilator (VLP2000E) that limits peak inspiratory pressure (PIP) during simultaneous ventilation with chest compressions was developed. OBJECTIVES: To evaluate the feasibility of VLP2000E ventilation during CPR and to compare monitored parameters versus bag-valve ventilation. METHODS: A randomized experimental study with 10 intubated pigs per group. After seven minutes of ventricular fibrillation, 2-minute CPR cycles were delivered. All animals were placed on VLP2000E after achieving return of spontaneous circulation (ROSC). RESULTS: Bag-valve and VLP2000E groups had similar ROSC rate (60% vs. 50%, respectively) and arterial oxygen saturation in most CPR cycles, different baseline tidal volume [0.764 (0.068) vs. 0.591 (0.123) L, p = 0.0309, respectively] and, in 14 cycles, different PIP [52 (9) vs. 39 (5) cm H2O, respectively], tidal volume [0.635 (0.172) vs. 0.306 (0.129) L], ETCO2[14 (8) vs. 27 (9) mm Hg], and peak inspiratory flow [0.878 (0.234) vs. 0.533 (0.105) L/s], all p < 0.0001. Dynamic lung compliance (≥ 0.025 L/cm H2O) decreased after ROSC in bag-valve group but was maintained in VLP2000E group [0.019 (0.006) vs. 0.024 (0.008) L/cm H2O, p = 0.0003]. CONCLUSIONS: VLP2000E ventilation during CPR is feasible and equivalent to bag-valve ventilation in ROSC rate and arterial oxygen saturation. It produces better respiratory parameters, with lower airway pressure and tidal volume. VLP2000E ventilation also prevents the significant decrease of dynamic lung compliance observed after bag-valve ventilation. Further preclinical studies confirming these findings would be interesting.

FUNDAMENTOS: Para ventilação prática e protetora durante a ressuscitação cardiopulmonar (RCP), desenvolveu-se um ventilador mecânico (VLP2000E) de 150 gramas que limita o pico de pressão inspiratória (PPI) durante ventilação e compressões torácicas simultâneas. OBJETIVOS: Avaliar a viabilidade da ventilação com VLP2000E durante RCP e comparar os parâmetros monitorados versus ventilação com bolsa-válvula. MÉTODOS: Estudo experimental randomizado com 10 porcos intubados por grupo. Após sete minutos de fibrilação ventricular, iniciaram-se ciclos de RCP de 2 minutos. Todos os animais foram ventilados com VLP2000E após o retorno da circulação espontânea (RCE). RESULTADOS: Os grupos bolsa-válvula e VLP2000E apresentaram taxa de RCE (60% vs. 50%, respectivamente) e saturação arterial de oxigênio similares na maioria dos ciclos de RCP, volume corrente basal diferente [0,764 (0,068) vs. 0,591 (0,123) L, p = 0,0309, respectivamente] e, em 14 ciclos, diferentes PPI [52 (9) vs. 39 (5) cm H2O, respectivamente], volume corrente [0,635 (0,172) vs. 0,306 (0,129) L], ETCO2 [14 (8) vs. 27 (9) mm Hg], e pico de fluxo inspiratório [0,878 (0,234) vs. 0,533 (0,105) L/s], todos p < 0,0001. A complacência pulmonar dinâmica (≥ 0,025 L/cm H2O) diminuiu após o RCE no grupo bolsa-válvula, mas se manteve no grupo VLP2000E [ 0,019 (0,006) vs. 0,024 (0,008) L/cm H2O, p = 0,0003]. CONCLUSÕES: Ventilação com VLP2000E durante RCP é viável e equivalente a ventilação com bolsa-válvula quanto à taxa de RCE e saturação arterial de oxigênio. Esse ventilador produz melhores parâmetros respiratórios, com pressão das vias aéreas e volume corrente menores. Ventilação com VLP2000E também previne a redução significante da complacência pulmonar dinâmica observada após ventilação com bolsa-válvula. Seria interessante realizar mais estudos pré-clínicos para confirmar esses resultados.

RESUMO

Visceral leishmaniasis (VL) is a chronic vector-borne zoonotic disease caused by trypanosomatids, considered endemic in 98 countries, mainly associated with poverty. About 50,000-90,000 cases of VL occur annually worldwide, and Brazil has the second largest number of cases in the world. The clinical picture of VL is fever, hepatosplenomegaly, and pancytopenia, progressing to death in 90% of cases due to secondary infections and multi-organ failure, if left untreated. We describe the case of a 25-year-old female who lived in the metropolitan area of Sao Paulo, who had recently taken touristic trips to several rural areas in Southeastern Brazil and was diagnosed post-mortem. During the hospitalization in a hospital reference for the treatment of COVID-19, the patient developed acute respiratory failure, with chest radiographic changes, and died due to refractory shock. The ultrasound-guided minimally invasive autopsy diagnosed VL (macrophages containing amastigote forms of Leishmania in the spleen, liver and bone marrow), as well as pneumonia and bloodstream infection by gram-negative bacilli.

RESUMO

Aim: In-hospital paediatric cardiopulmonary resuscitation (CPR) survival has been improving in high-income countries. This study aimed to analyse factors associated with survival and neurological outcome after paediatric CPR in a middle-income country. Methods: This observational study of in-hospital cardiac arrest using Utstein-style registry included patients <18 years old submitted to CPR between 2015 and 2020, at a high-complexity hospital. Outcomes were survival and neurological status assessed using Paediatric Cerebral Performance Categories score at prearrest, discharge, and after 180 days. Results: Of 323 patients who underwent CPR, 108 (33.4%) survived to discharge and 93 (28.8%) after 180 days. In multivariable analysis, lower survival at discharge was associated with liver disease (OR 0.060, CI 0.007-0.510, p = 0.010); vasoactive drug infusion before cardiac arrest (OR 0.145, CI 0.065-0.325, p < 0.001); shock as the immediate cause (OR 0.183, CI 0.069-0.486, p = 0.001); resuscitation > 30 min (OR 0.070, CI 0.014-0.344, p = 0.001); and bicarbonate administration during CPR (OR 0.318, CI 0.130-0.780, p = 0.01). The same factors remained associated with lower survival after 180 days. Neurological outcome was analysed in the 93 survivors after 180 days following CPR. Prearrest neurological dysfunction was observed in 31.4%, and neurological prognosis was favourable in 79.7% at discharge and similar after 180 days. Conclusion: In-hospital paediatric cardiac arrest patients with complex chronic conditions had lower survival associated with liver disease, shock as cause of cardiac arrest, vasoactive drug infusion before cardiac arrest, bicarbonate administration during CPR, and prolonged resuscitation. Most survivors had favourable neurological outcome.

RESUMO

ABSTRACT Objective: We assessed metrics related to inpatient glycemic control using InsulinAPP, an application available for free in Brazil, on the hospitalist-managed ward of our hospital. Subjects and methods: We performed a retrospective study of patients with type 2 diabetes (T2D) admitted from November 2018 to October 2019. InsulinAPP recommends NPH and regular insulins three times a day, in bolus-correction or basal-bolus schemes. Parameters that included BG within range of 70-180 mg/dL, insulin treatment regimen and frequency of hypoglycemia were evaluated. Results: A total of 147 T2D individuals (23% medicine and 77% surgery) were included (mean age 62.3 ± 12.7 years, HbA1c: 8.3 ± 3.0%). The initial insulin regimen was 50% bolus-correction, 47% basal-bolus and 3% with sliding scale insulin. During hospitalization, 71% patients required a bolus-basal regimen. In the first 10 days of the protocol, 71% BG measurements were between 70-180 mg/dL and 26% patients experienced one or more episodes of hypoglycemia < 70 mg/dL, and 5% with BG < 54 mg/dL. Conclusion: The results of this retrospective study indicate the InsulinAPP application using human insulin formulations was effective and safe for the management of hyperglycemia on a hospitalist-managed ward, with more than 70% BG measurements within the therapeutic range and a low rate of hypoglycemia.

RESUMO

Patients hospitalized for acute medical and surgical illnesses are at risk of developing venous thromboembolism (VTE) during hospitalization and after discharge. Extended pharmacological prophylaxis beyond the hospital stay is recommended for patients undergoing surgeries at high risk for VTE and for selected groups of hospitalized medical patients. This practice involves several challenges, from identification of at-risk populations eligible for extended prophylaxis to choice of the most appropriate anticoagulant and definition of the ideal duration of use. This review will present the main VTE risk assessment models for hospitalized medical and surgical patients, the current recommendations for use of extended prophylaxis, and its limitations and benefits.

RESUMO

Resumo Pacientes hospitalizados por doenças clínicas e cirúrgicas agudas estão sob risco de desenvolvimento de tromboembolismo venoso (TEV) durante a hospitalização e após a alta. A profilaxia farmacológica estendida além do período da hospitalização é recomendada para pacientes submetidos a cirurgias de alto risco de TEV e para grupos selecionados de pacientes clínicos hospitalizados. Diversos desafios envolvem essa prática, desde o reconhecimento das populações de risco elegíveis para a extensão da profilaxia até a escolha do anticoagulante mais adequado e a definição do tempo ideal de utilização. Os principais modelos de avaliação de risco de TEV em pacientes clínicos e cirúrgicos hospitalizados, as recomendações atuais para uso da profilaxia estendida e suas limitações e benefícios serão apresentados nesta revisão.

RESUMO

Resumo: Introdução: A parada cardiorrespiratória é um evento emergencial que requer tanto a identificação precoce de sinais de deterioração clínica quanto ações rápidas e eficazes para a sua reversão. Muitos médicos e enfermeiros que atendem crianças procuram se capacitar no atendimento desses eventos, realizando o curso Pediatric Advanced Life Support (PALS), tornando-se posteriormente instrutores. O objetivo desta pesquisa foi conhecer a percepção do instrutor de PALS sobre seu papel na articulação entre o cenário simulado e o real da ressuscitação pediátrica. Método: Trata-se de uma abordagem qualitativa em que se utilizou a entrevista semiestruturada como técnica de pesquisa. Foram realizadas 12 entrevistas com instrutores do PALS vinculados a variados centros de treinamento em São Paulo. Os dados qualitativos das entrevistas seguiram o método de análise proposto por Minayo, e o marco teórico adotou os conceitos de campo e habitus de Pierre Bourdieu. Resultados: A análise das entrevistas mostrou que os médicos e enfermeiros se sentem reconhecidos e seguros, conduzem melhor a equipe, realizam intervenção construtiva, sugerem mais treinamentos em ressuscitação pediátrica e implantam melhorias nos serviços após se tornarem instrutores do PALS. O habitus incorporado no campo simulado foi reproduzido pelos instrutores no campo da assistência, exceto na aplicação do debriefing. Conclusão: O papel dos instrutores foi de multiplicação das boas práticas, envolvendo as equipes e favorecendo a realização de atendimentos sistematizados e baseados em evidências, com resultados positivos no dia a dia das instituições hospitalares.

Abstract: Introduction: Cardiopulmonary arrest is an emergency event that requires both early identification of signs of clinical deterioration and rapid and effective actions for its reversal. Many physicians and nurses who provide care for children seek to training in this area of care by completing the Pediatric Advanced Life Support (PALS) course, and subsequently becoming an instructor. The aim of this research was to understand the PALS instructors' views on their role in connecting simulated scenarios to real life pediatric resuscitation situations. Method: The article has a qualitative approach and semi-structured interviews were used as the research technique. Twelve interviews were conducted with PALS instructors linked to various training centers in São Paulo. For qualitative analysis of the interviews the method proposed by Minayo was used, and Pierre Bourdieu's field and habitus theoretical framework was also adopted. Results: Analysis of the interviews showed that after becoming PALS instructors, physicians and nurses feel recognized and self-confident, are better team leaders, make constructive interventions, suggest more training in pediatric emergencies and implement improvements in their services. The built-in habitus in the simulated field was reproduced by the instructors in the field of assistance, except in the debriefing application. Conclusion: The role of the instructors was to multiply best practices, involving the teams and favoring the execution of systematized and evidence-based care, with positive results in the day-to-day of hospital institutions.

RESUMO

INTRODUCTION: The retention of cardiopulmonary resuscitation skills and the ideal frequency of retraining remain unanswered. This study investigated the retention of cardiopulmonary resuscitation skills by medical students for up to 42 months after training. METHODS: In a cross-sectional study, 205 medical students received 10 hours of training in basic life support in 3 practical classes, during their first semester at school. Then, they were divided into 4 groups, according to the time elapsed since the training: 73 after 1 month, 55 after 18 months, 41 after 30 months, and 36 after 42 months. Nineteen cardiopulmonary resuscitation skills and 8 potential technical errors were evaluated by mannequin-based simulation and reviewed using filming. RESULTS: The mean retention of the skills was 90% after 1 month, 74% after 18 months, 62% after 30 months, and 61% after 42 months (P < 0.001). The depth of chest compressions had the greatest retention over time (87.8%), with no significant differences among groups. Compressions performed greater than 120 per minute were less likely to be done with adequate depth. Ventilation showed a progressive decrease in retention from 93% (n = 68) after 1 month to 19% (n = 7) after 42 months (P < 0.001). All 205 students were able to turn the automated external defibrillator on and deliver the shock. CONCLUSIONS: The depth of chest compressions and the use of an automated external defibrillator were the skills with the highest retention over time. Based on a skills retention prediction curve, we suggest that 18 to 24 months as the minimum retraining interval to maintain at least 70% of skills.

RESUMO

Times de Resposta Rápida (TRR) são equipes multidisciplinares treinadas para atender indivíduos com intercorrências agudas e graves, incluindo parada cardiorrespiratória (PCR) súbita, nas unidades de internação. O objetivo deste trabalho é discutir as particularidades do emprego de um TRR hospitalar no atendimento de PCRs extra-hospitalares, utilizando a experiência do time do Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ICHC-FMUSP) para elucidação. Metodologia: Estudo retrospectivo, descritivo, utilizando o banco de dados do TRR do ICHC-FMUSP. Foram levantados todos os casos classificados como PCR súbita atendidos em ambiente extra-hospitalar, nos anos de 2014 a 2016. Dados globais de cinco pacientes que evoluíram com alta hospitalar e nível neurológico preservado foram descritos e analisados em detalhes. Resultados: Entre 11 atendimentos, oito tiveram retorno da circulação espontânea (RCE) na cena (72,2%) e três morreram no local. Dos oito pacientes admitidos com vida no Departamento de Emergência, cinco tiveram alta hospitalar após o evento (45,5%). A média de tempo de resposta foi 3 ± 1,2 minutos e o intervalo chamada-choque foi de 7,25 ± 3,2 minutos. Os ritmos de parada foram fibrilação ventricular (80%) e atividade elétrica sem pulso (20%). Dois pacientes foram diagnosticados com doença coronariana grave e quatro receberam um cardiodesfibrilador implantável (CDI) para profilaxia secundária de morte súbita. Um paciente, entre os cinco que tiveram alta, faleceu em outro serviço. Conclusão: Apesar de pouco usual, o emprego de um TRR hospitalar no atendimento de PCRs extra-hospitalares pode ser benéfico. Os desfechos favoráveis provavelmente decorreram do treinamento da equipe e da rapidez na realização do atendimento. A investigação cardiológica dos sobreviventes identificou pacientes com doenças graves, que, portanto, mais se beneficiariam da assistência de um time especializado

Introduction: Rapid Response Teams (RRT) are multidisciplinary groups trained to treat individuals with severe and acute events, including sudden cardiac arrest (CA), in in-patient units. The aim of this report is to discuss the singularities of deploying a hospital RRT for out-of-hospital CA assistance, using the experience of the team at the Instituto Central of Hospital das Clínicas of the University of São Paulo School of Medicine (ICHC-FMUSP) as illustration. Methodology: A retrospective, descriptive analysis was conducted, using the RRT database of the ICHC-FMUSP. All cases classified as sudden CA treated outside of the hospital between 2014 and 2016 were surveyed. Global data for five patients who progressed to discharge from hospital free of neuro - logical impairment were described and analyzed in detail. Results: Of the 11 cases, 8 had return of spontaneous circulation (ROSC) at the scene (72.2%), and 3 died on site. Of the 8 patients admitted to the Emergency Department, 5 were discharged from the hospital after the event (45.5%). The average response time was 3±1.2minutes, and the call-to-shock time interval was 7.25±3.2minutes. The cardiac arrest rhythms were ventricular fibrillation (80%) and pulseless electrical activity (20%). Two patients were diagnosed with severe coronary disease and four received an implantable cardioverter-defibrillator (ICD) for secondary prophylaxis of sudden death. One patient, of the 5 discharged, died in another unit. Conclusion: Although unusual, the use of a hospital RRT for out-of-hospital CA assistance can be beneficial. The favorable outcomes likely resulted from the team's training and the speed with which the treatment was given. Cardiovascular evaluation of the survivors identified patents with severe diseases, which would, therefore, most benefit from the care of a specialized team

RESUMO

Objetivo: caracterizar os atendimentos clínicos realizados pelo SAMU de Salvador. Metodologia: trata-se de estudo descritivo, exploratório e transversal cuja amostra foi composta de 465 fichas de atendimentos clínicos realizados pelo SAMU, na cidade de Salvador na Bahia. Os dados foram obtidos por meio de instrumento de coleta de dados e a análise descritiva realizada com o software SPSS, no qual foram processadas frequências relativas e absolutas. Resultados: os usuários atendidos se caracterizaram por serem homens (49,9%) com média de idade de 54 anos [desvio-padrão (DP)=21)]. Os agravos neurológicos (36,1%), cardiológicos (14,4%) e respiratórios (12,9%) foram prevalentes. Unidades de suporte básico foram as mais acionadas (63,7%) e tiveram como principal desfecho o atendimento no local e remoção para um hospital de referência (21,7%), no entanto, recursos como oxigenoterapia e punção venosa não foram utilizados na maior parte dos atendimentos. A média de tempo entre a abertura da ocorrência e saída da base foi de 22 minutos (DP= 20). O tempo resposta teve média de 39 minutos (DP= 25) e a duração total média da ocorrência foi de duas horas (DP= 1:23). Conclusão: os atendimentos clínicos realizados pelo SAMU ocorrem prevalentemente com homens e por agravos neurológicos. Identificou-se discordância entre a necessidade dos pacientes e o envio de recursos, mediante a avaliação da equipe. Os tempos implicados no atendimento pré-hospitalar são elevados.(AU)

Objectives: to characterize the clinical care provided by SAMU of Salvador. Methodology: this is a descriptive, exploratory and cross-sectional study whose sample consisted of 465 records of clinical care performed by the SAMU, in the city of Salvador, Bahia. Data was obtained through a data collection instrument and descriptive analysis was performed with the SPSS software, in which relative and absolute frequencies were processed. Results: the patients attended were characterized by being men (49.9%) with a mean age of 54 years old [Standard Deviation (SD)=21)]. Neurological (36.1%), cardiac (14.4%) and respiratory (12.9%) injuries were prevalent. Basic support units were the most triggered (63.7%) and their main outcome was onsite care and removal to a reference hospital (21.7%); however, resources such as oxygen therapy and venipuncture were not used in most calls. The mean time between the opening of the occurrence and the output was 22 minutes (SD=20). The mean response time was 39 minutes (SD=25) and the total mean duration of occurrence was two hours (SD=1:23). Conclusion: SAMU clinical consultations occur predominantly with men and neurological disorders. Disagreement was identified between the patients' need and the dispatching of resources, according to the team's evaluation. The times involved in pre-hospital care are high.(AU)

RESUMO

OBJECTIVES: To describe clinical complications related to colonoscopy in inpatients with multiple diseases. Among the known complications, acute kidney injury was the primary focus. METHODS: This was an observational retrospective study of 97 inpatients. Data relating to age; gender; comorbidities; current medication; blood tests (renal function, blood glucose and LDL cholesterol levels); length of hospital stay; indication, results, and complications of colonoscopies; and time to the development of kidney injury were collected between June 2011 to February 2012. RESULTS: A total of 108 colonoscopies (9 screening and 88 diagnostic) were conducted in 97 patients. Renal injury occurred in 41.2% of the patients. The univariate analysis revealed that kidney injury was related to the use of diuretics, statins, calcium channel blockers, and angiotensin converting enzyme inhibitor; however, the multivariate analysis showed that only the use of diuretics was associated with kidney injury. The occurrence of kidney injury and the time to its development were independent of the previous glomerular filtration rate as calculated with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. CONCLUSIONS: The use of diuretics was the only independent variable associated with the development of kidney injury in inpatients with multiple comorbidities who underwent colonoscopy. The occurrence of kidney injury and the time to its development were independent of previous CKD-EPI-based assessments of renal function. These results highlight the increased risk of colonoscopy in such patients, and its indication should be balanced strictly and perhaps avoided as a screening test.

RESUMO

The data presented in this article are related to the research article, "The Use of End-Tidal Carbon Dioxide (ETCO2) Measurement to Guide Management of Cardiac Arrest: A Systematic Review" [1]. This article is a systematic review and meta-analysis of existing data on the subject of whether any level of end-tidal carbon dioxide (ETCO2) measured during cardiopulmonary resuscitation (CPR) correlates with return of spontaneous circulation (ROSC) or survival in adult patients experiencing cardiac arrest in any setting. These data are made publicly available to enable critical or extended analyses.

RESUMO

AIMS: To identify whether any level of end-tidal carbon dioxide (ETCO2) measured during cardiopulmonary resuscitation (CPR) correlates with return of spontaneous circulation (ROSC) or survival in adults experiencing cardiac arrest in any setting. METHODS: Systematic review. We included randomized controlled trials, cohort studies, and case-control studies of adult cardiac arrest in any setting that reported specific (rather than pooled) ETCO2 values and attempted to correlate those values with prognosis. Full-text articles were searched on EmBASE, MEDLINE, and Cochrane Database. The Grades of Recommendation, Assessment, Development and Evaluation (GRADE) guidelines were followed, assigning levels of quality to all evidence used in the meta-analysis. RESULTS: Seventeen observational studies, describing a total of 6198 patients, were included in the qualitative synthesis, and five studies were included in the meta-analysis. The available studies provided consistent but low-quality evidence that ETCO2 measurements ≥10mmHg, obtained at various time points during CPR, are substantially related to ROSC. Additional cut-off values were also found. Initial ETCO2 or 20-min ETCO2>20mmHg appears to be a better predictor of ROSC than the 10mmHg cut off value. A ETCO2<10mmHg after 20min of CPR is associated with a 0.5% likelihood of ROSC. CONCLUSIONS: Based upon existing evidence, ETCO2 levels do seem to provide limited prognostic information for patients who have experienced cardiac arrest. Given the many potential confounders that can influence initial ETCO2 levels, extreme or trending values may be more useful than static mid-range levels. Additional well-designed studies are needed to define optimal timing for the measurement of ETCO2 for prognostic purposes.

RESUMO

OBJECTIVES: To describe clinical complications related to colonoscopy in inpatients with multiple diseases. Among the known complications, acute kidney injury was the primary focus. METHODS: This was an observational retrospective study of 97 inpatients. Data relating to age; gender; comorbidities; current medication; blood tests (renal function, blood glucose and LDL cholesterol levels); length of hospital stay; indication, results, and complications of colonoscopies; and time to the development of kidney injury were collected between June 2011 to February 2012. RESULTS: A total of 108 colonoscopies (9 screening and 88 diagnostic) were conducted in 97 patients. Renal injury occurred in 41.2% of the patients. The univariate analysis revealed that kidney injury was related to the use of diuretics, statins, calcium channel blockers, and angiotensin converting enzyme inhibitor; however, the multivariate analysis showed that only the use of diuretics was associated with kidney injury. The occurrence of kidney injury and the time to its development were independent of the previous glomerular filtration rate as calculated with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. CONCLUSIONS: The use of diuretics was the only independent variable associated with the development of kidney injury in inpatients with multiple comorbidities who underwent colonoscopy. The occurrence of kidney injury and the time to its development were independent of previous CKD-EPI-based assessments of renal function. These results highlight the increased risk of colonoscopy in such patients, and its indication should be balanced strictly and perhaps avoided as a screening test.
