The Prognostic Impact of Renal Failure in Patients with ST-Segment Elevation Acute Myocardial Infarction

INTRODUCTION: Renal insufficiency (RI) is associated with higher morbidity and mortality in patients (P) with coronary artery disease and in P submitted to angioplasty. In ST-segment elevation acute myocardial infarction (STEAMI), this impact has not been well demonstrated. AIM: To evaluate the impact of RI in P with STEAMI. METHODS: We evaluated 160 P admitted with STEAMI, mean age of 62+/-14 years, 76% male. We determined creatinine levels on admission. RI was defined as a level >1.5 mg/dl. Analysis of clinical, electrocardiographic and laboratory variables was performed, in relation to the endpoint defined as the occurrence of death at 30-day follow-up. RESULTS: There were 16 deaths (10%) at 30-day follow-up. P with RI (n=21) were older (68+/-11 vs 61+/-14 years, p<0.001), more often had diabetes (57 vs 24 %, p=0.004) and presented more often with Killip class > or =2 (57 vs 12%, p<0.001). The use of statins (62 vs 83%, p=0.05) and beta-blockers (24 vs 65%, p<0.001) was lower in P with RI. Mortality was higher in RI P (62 vs 2%, p<0.001). The univariate predictors of death were age > or =75 years, diabetes, Killip class > or =2 on admission, RI, non-use of statins and beta-blockers and use of diuretics. In multivariate analysis, independent predictors of death at 30 days were RI (HR 29.6, 95% CI 6.3-139.9, p<0.001) and non-use of beta-blockers (HR 0.13, 95% CI 0.02-1.01, p=0.01). CONCLUSION: In P admitted for STEAMI, the presence of RI was an independent predictor of death at 30 days whereas the usage of beta-blockers was protective.

Correlação da Variação dos Níveis de NT-ProBNP com a Modificação da Capacidade Funcional em Doentes com Insuficiência Cardíaca Crónica

OBJECTIVE: We set out to evaluate whether changes in N-terminal pro-brain natriuretic peptide (proBNP) can predict changes in functional capacity, as determined by cardiopulmonary exercise testing (CPET), in patients with chronic heart failure (CHF) due to dilated cardiomyopathy (DCM). METHODS: We studied 37 patients with CHF due to DCM, 81% non-ischemic, 28 male, who performed symptom-limited treadmill CPET, with the modified Bruce protocol, in two consecutive evaluations, with determination of proBNP after 10 minutes rest prior to CPET. The time between evaluations was 9.6+/-5.5 months, and age at first evaluation was 41.1+/-13.9 years (21 to 67). RESULTS IN THE FIRST AND SECOND EVALUATIONS RESPECTIVELY WERE: NYHA functional class >II 51% and 16% (p<0.001), sinus rhythm 89% and 86.5% (NS), left ventricular ejection fraction 24.9+/-8.9% and 26.6+/-8.6% (NS), creatinine 1.03+/-0.25 and 1.09+/-0.42 mg/dl (NS), taking ACE inhibitors or ARBs 94.5% and 100% (NS), beta-blockers 73% and 97.3% (p<0.001), and spironolactone 89% and 89% (NS). We analyzed the absolute and percentage variation (AV and PV) in peak oxygen uptake (pVO2--ml/kg/min) and proBNP (pg/ml) between the two evaluations. RESULTS: (1) pVO2 AV: -17.4 to 15.2 (1.9+/-5.7); pVO2 PV: -56.1 to 84% (11.0+/-25.2); proBNP AV: -12850 to 5983 (-778.4+/-3332.5); proBNP PV: -99.0 to 379.5% (-8.8+/-86.3); (2) The correlations obtained--r value and p value [r (p)]--are shown in the table below; (3) We considered that a coefficient of variation of pVO2 PV of >10% represented a significant change in functional capacity. On ROC curve analysis, a proBNP PV value of 28% showed 80% sensitivity and 79% specificity for pVO2 PV of >10% (AUC=0.876, p=0.01, 95% CI 0.75 to 0.99). CONCLUSIONS: In patients with CHF due to DCM, changes in proBNP values correlate with variations in pVO2, as assessed by CPET. However, our results suggest that only a proBNP PV of >28% predicts a significant change in functional capacity.

Impacto da Combinação de Terapêutica Farmacológica na Mortalidade em Doentes com Síndrome Coronária Aguda

INTRODUCTION: Conventional risk stratification after acute myocardial infarction is usually based on the extent of myocardial damage and its clinical consequences. However, nowadays, more aggressive therapeutic strategies are used, both pharmacological and invasive, with the aim of changing the course of the disease. OBJECTIVES: To evaluate whether the number of drugs administered can influence survival of these patients, based on recent clinical trials that demonstrated the benefit of each drug for survival after acute coronary events. METHODS: This was a retrospective analysis of 368 consecutive patients admitted to our ICU during 2002 for acute coronary syndrome. A score from 1 to 4 was attributed to each patient according to the number of secondary prevention drugs administered--antiplatelets, beta blockers, angiotensin-converting enzyme inhibitors and statins--independently of the type of association. We evaluated mortality at 30-day follow-up. RESULTS: Mean age was 65 +/- 13 years, 68% were male, and 43% had ST-segment elevation acute myocardial infarction. Thirty-day mortality for score 1 to 4 was 36.8%, 15.6%, 7.8% and 2.5% respectively (p < 0.001). The use of only one or two drugs resulted in a significant increase in the risk of death at 30 days (OR 4.10, 95% CI 1.69-9.93, p = 0.002), when corrected for other variables. There was a 77% risk reduction associated with the use of three or four vs. one or two drugs. The other independent predictors of death were diabetes, Killip class on admission and renal insufficiency. CONCLUSIONS: The use of a greater number of secondary prevention drugs in patients with acute coronary syndromes was associated with improved survival. A score of 4 was a powerful predictor of mortality at 30-day follow-up

Impacto da Estimulação Vagal na Indução e Interrupção de Fibrilhação Auricular no Modelo do Coração de Coelho in Vivo

INTRODUCTION: Vagal activity is thought to influence atrial electrophysiological properties and play a role in the initiation and maintenance of atrial fibrillation (AF). In this study, we assessed the effects of acute vagal stimulation (vagus_stim) on atrial conduction times, atrial and pulmonary vein (PV) refractoriness, and vulnerability to induction of AF in the rabbit heart with intact autonomic innervation. METHODS: An open-chest epicardial approach was performed in 11 rabbits (New Zealand; 3.9-5.0 kg), anesthetized and artificially ventilated after neuromuscular blockade. A 3-lead ECG was obtained. Atrial electrograms were recorded along the atria, from right to left (four monopolar electrodes), together with a circular electrode adapted for proximal left PV assessment. Acute vagus nerve stimulation was obtained with bipolar electrodes (20 Hz). Epicardial activation was recorded in sinus rhythm, and the conduction time from right (RA) to left atrium (LA), and from RA to PVs, was measured in basal conditions and during vagus_stim. The atrial effective refractory period (ERP) and dispersion of refractoriness (Disp_A) were analyzed. Vulnerability to AF induction was assessed at the right (RAA) and left (LAA) atrial appendages and the PVs. Atrial stimulation (50 Hz) was performed alone or combined with vagus_stim. Heart rate and blood pressure were monitored. RESULTS: In basal conditions, there was a significant delay in conduction from RA to PVs, not influenced by vagus_stim, and the PV ERPs were shorter than those measured in LA and LAA, but without significant differences compared to RA and RAA. During vagus_stim, conduction times between RA and LA increased from 16+8 ms to 27+6 ms (p < 0.05) and ERPs shortened significantly in RA, LAA and LA (p < 0.05), but not in RAA. There were no significant differences in Disp_A. AF induction was reproducible in 45% of cases at 50 Hz and in 100% at 50 Hz+vagus_stim (p < 0.05). The duration of inducible AF increased from 1.0 +/- 0.2 s to 12.0 +/- 4.5 s with 50 Hz+vagus_stim (p < 0.01). AF lasted >10 s in 45.4% of rabbits during vagus_stim, and ceased after vagus_stim in 4 out of these 5 cases. In 3 animals, PV tachycardia, with fibrillatory conduction, induced with 50 Hz PV pacing during vagus_stim. CONCLUSIONS: Vagus_stim reduces interatrial conduction velocity and significantly shortens atrial ERP, contributing to the induction and duration of AF episodes in the in vivo rabbit heart. This model may be useful for the assessment of autonomic influence on the pathophysiology of AF.

Impacto da Obesidade nos Resultados após Angioplastia Primária em Doentes com Enfarte Agudo do Miocárdio com Elevação do Segmento ST

INTRODUCTION: Obesity is an important risk factor for the development of diabetes, hypertension, coronary disease, left ventricular dysfunction, stroke and cardiac arrhythmias. Paradoxically, previous studies in patients undergoing elective coronary angioplasty showed a reduction in hospital and long-term mortality in obese patients. The relation with body mass index (BMI) has been less studied in the context of primary angioplasty. OBJECTIVES: To evaluate the impact of obesity on the results of ST-segment elevation acute myocardial infarction treated by primary angioplasty. METHODS: This was a study of 464 consecutive patients with ST-segment elevation acute myocardial infarction undergoing primary angioplasty, 78% male, mean age 61 +/- 13 years. We assessed in-hospital, 30-day and one-year mortality according to BMI. Patients were divided into three groups according to BMI: normal--18-24.9 kg/m2 (n = 171); overweight--25-29.9 kg/m2 (n = 204); and obese-- > 30 kg/m2 (n = 89). RESULTS: Obese patients were younger (ANOVA, p < 0.001) and more frequently male (p = 0.014), with more hypertension (p = 0.001) and dyslipidemia (p = 0.006). There were no differences in the prevalence of diabetes, previous cardiac history, heart failure on admission, anterior location, multivessel disease, peak total CK or medication prescribed, except that obese patients received more beta-blockers (p = 0.049). In-hospital mortality was 9.9% for patients with normal BMI, 3.4% for overweight patients and 6.7% for obese patients (p = 0.038). Mortality at 30 days was 11 4.4% and 7.8% (p = 0.032) and at one year 12.9%, 4.9% and 9% (p = 0.023), respectively. On univariate analysis, overweight was the only BMI category with a protective effect; however, after multivariate logistic regression analysis, adjusted for confounding variables, none of the BMI categories could independently predict outcome. CONCLUSIONS: Overweight patients had a better prognosis after primary angioplasty for ST-segment elevation acute myocardial infarction compared with other BMI categories, but this was dependent on other potentially confounding variables.

Impacto da Idade no Tratamento e Resultados Após Enfarte Agudo do Miocárdio em Particular nos Muito Idosos

INTRODUCTION: The elderly population admitted for acute myocardial infarction is increasing. This group is not well studied in international trials and is probably treated with a more conservative approach. OBJECTIVES: To evaluate the presentation and treatment of myocardial infarction according to age, particularly in very elderly patients. METHODS: We studied 1242 consecutive patients admitted with acute myocardial infarction, assessing in-hospital, 30-day and one-year mortality during follow-up for each age-group. Patients were divided into four groups according to age: <45 years (7.6%); 45-64 years (43.3%); 65-74 years (23.4%); and ≥75 years (25.7%). RESULTS: Elderly patients had a worse risk profile (except for smoking), more previous history of coronary disease and a worse profile on admission, with the exception of lipid profile, which was more favorable. With regard to treatment of the elderly, although less optimized than in other age-groups, it was significantly better compared to other registries, including for percutaneous coronary angioplasty. Both complications and mortality were worse in the older groups. In elderly patients (≥75 years), adjusted risk of mortality was 4.9-6.3 times higher (p<0.001) than patients in the reference age-group (45-64 years). In these patients, the independent predictors of death were left ventricular function and renal function, use of beta-blockers being a predictor of survival. CONCLUSIONS: Elderly patients represent a substantial proportion of the population admitted with myocardial infarction, and receive less evidenced-based therapy. Age is an independent predictor of short- and medium-term mortality.

Prognostic Value of a New Cardiopulmonary Exercise Testing Parameter in Chronic Heart Failure: Oxygen Uptake Efficiency at Peak Exercise - Comparison with Oxygen Uptake Efficiency Slope

INTRODUCTION: A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O(2) consumption (VO(2)) and minute ventilation (VE) in patients with chronic heart failure (CHF). OBJECTIVE: To evaluate the prognostic value of a new CPET parameter - peak oxygen uptake efficiency (POUE) - and to compare it with OUES in patients with CHF. METHODS: We prospectively studied 206 consecutive patients with stable CHF due to dilated cardiomyopathy - 153 male, aged 53.3±13.0 years, 35.4% of ischemic etiology, left ventricular ejection fraction 27.7±8.0%, 81.1% in sinus rhythm, 97.1% receiving ACE-Is or ARBs, 78.2% beta-blockers and 60.2% spironolactone - who performed a first maximal symptom-limited treadmill CPET, using the modified Bruce protocol. In 33% of patients an cardioverter-defibrillator (ICD) or cardiac resynchronization therapy device (CRT-D) was implanted during follow-up. Peak VO(2), percentage of predicted peak VO(2), VE/VCO(2) slope, OUES and POUE were analyzed. OUES was calculated using the formula VO(2) (l/min) = OUES (log(10)VE) + b. POUE was calculated as pVO(2) (l/min) / log(10)peakVE (l/min). Correlation coefficients between the studied parameters were obtained. The prognosis of each variable adjusted for age was evaluated through Cox proportional hazard models and R2 percent (R2%) and V index (V6) were used as measures of the predictive accuracy of events of each of these variables. Receiver operating characteristic (ROC) curves from logistic regression models were used to determine the cut-offs for OUES and POUE. RESULTS: pVO(2): 20.5±5.9; percentage of predicted peak VO(2): 68.6±18.2; VE/VCO(2) slope: 30.6±8.3; OUES: 1.85±0.61; POUE: 0.88±0.27. During a mean follow-up of 33.1±14.8 months, 45 (21.8%) patients died, 10 (4.9%) underwent urgent heart transplantation and in three patients (1.5%) a left ventricular assist device was implanted. All variables proved to be independent predictors of this combined event; however, VE/VCO2 slope was most strongly associated with events (HR 11.14). In this population, POUE was associated with a higher risk of events than OUES (HR 9.61 vs. 7.01), and was also a better predictor of events (R2: 28.91 vs. 22.37). CONCLUSION: POUE was more strongly associated with death, urgent heart transplantation and implantation of a left ventricular assist device and proved to be a better predictor of events than OUES. These results suggest that this new parameter can increase the prognostic value of CPET in patients with CHF.

Atrofia Muscular Espinhal: Análise Descritiva de Uma Série de Casos

Introdução: A Atrofia Muscular Espinhal (AME) é o nome dado a uma doença neuromuscular específica caracterizada pela degeneração dos neurónios motores medulares, condicionando atrofia e fraqueza muscular progressivas. É determinada pela alteração do gene Survival Motor Neuron-1 (SMN1), localizado no braço longo do cromossoma cinco. Uma cópia quase idêntica do gene SMN1, chamada SMN2, modula a gravidade da doença. A AME repercute-se a nível de vários órgãos e sistemas, envolvendo frequentemente os sistemas respiratório, osteoarticular e gastrintestinal. Estão descritos vários subtipos da doença, com base quer na idade do início dos sintomas quer na máxima aquisição motora alcançada. Objectivos: Estudar a população de doentes com o diagnóstico de AME (clínico e/ou genético) seguida na Consulta de Medicina Física e de Reabilitação (CMFR) do Hospital de Dona Estefânia (HDE) em Lisboa, no período de Janeiro de 2007 a Outubro de 2009. Métodos: Estudo retrospectivo com análise de parâmetros sócio-demográficos, clínica, exames complementares de diagnóstico, evolução e complicações da doença. Resultados e Discussão: A casuística é constituída por doze doentes, com idades compreendidas entre os 0 meses e os 21 anos de idade, tendo sete o diagnóstico de AME I, um AME II equatro o diagnóstico de AME tipo III. Verificou-se que a gravidade da doença era inversamente proporcional à idade no início dos sintomas e à função motora máxima atingida pelo indivíduo durante o seu desenvolvimento. Todos os doentes apresentaram infecções respiratórias recorrentes e nos óbitos ocorridos, verificou-se como causa de morte a insuficiência respiratória, complicada de paragem cardio-respiratória. As principais complicações ortopédicas foram o desenvolvimento de contracturas articulares das grandes articulações dos membros inferiores, bem como o desenvolvimento de escoliose. A disfagia foi a principal complicação gastrenterológica. Conclusão: A não aquisição de etapas do desenvolvimento motor está correlacionada com um agravamento do prognóstico funcional e vital.

Paralisia Facial Periférica. O Papel da Medicina Física e de Reabilitação

A paralisia facial periférica (PFP) resulta da lesão neuronal periférica do nervo facial (NF). Pode ser primária (Paralisia de Bell) ou secundária. Além do quadro clínico clássico, que tipicamente envolve os dois andares da hemiface afectada, pode apresentar-se com outros sintomas acompanhantes(ex. xeroftalmia, hiperacúsia, alteração da fonação e deglutição), que importa pesquisar. A avaliação clínica inclui a aferição rigorosa do tónus muscular e da sensibilidade do território do NF. Alguns instrumentos permitem maior objectividade na avaliação dos doentes (Sistema de House-Brackmann, Sistema de Graduação Facial, Avaliação Funcional). Há critérios claros de referenciação à especialidade de Medicina Física e de Reabilitação. O tratamento da Paralisia de Bell pode englobar a terapêutica farmacológica, a reeducação neuromuscular (RNM), os métodos físicos e a cirurgia. Dentro da RNM, sistematizam-se as várias técnicas de tratamento. As estratégias do plano terapêutico devem ser orientadas por problemas e ajustadas aos sintomas e sinais do doente. Revê-se o papel dos métodos físicos. Cerca de 15-20% dos doentes fica com sequelas permanentes após três meses de evolução. A PFP é uma condição frequentemente pluridisciplinar, importando conhecer as estratégias disponibilizadas pela Medicina de Reabilitação.

Temporomandibular Joint Ankylosis in an Infant: A Rare Cause of Difficult Airway

1.Pre-assessment data of the patient A 2-year-old boy, weighing 15 kg was admitted with a history of limited mouth opening(inter-incisor distance of 6 mm), hypoplastic and retrognathic mandible (bird face deformity) and facial asymmetry from left temporomandibular joint ankylosis (TMJA). He was born at term, after an uneventful pregnancy, and there was no report of trauma during caesarean section. No other possible aetiologies were identified. He was scheduled for mandibular osteotomy. Preoperative ENT examination revealed adenotonsillar hypertrophy. 2. Anaesthetic Plan A fiberoptic nasal intubation was performed under deep inhalation anaesthesia with sevoflurane, with the patient breathing spontaneously. Midazolam (0.05 mg.kg-1) and alfentanil (0.03 mg.kg-1) were given and anaesthesia was maintained with O2/air and sevoflurane. No neuromuscular blocking agent was administered since the surgical team needed facial nerve monitoring. 3. Description of incident During surgery an accidental extubation occurred and an attempt was made to reintubate the trachea by direct laryngoscopy. Although the osteotomy was nearly completed, the vocal cords could not be visualized (Cormack-Lehane grade IV laryngoscopic view). 4. Solving the problem Re-intubation was finally accomplished with the flexible fiberscope and the procedure was concluded without any more incidents. Extubation was performed 24 hours postoperatively with the patient fully awake. After surgery mouth opening improved to inter-incisor gap of 15 mm. 5. Lessons learned and take home message Two airways issues present in this case can lead to difficultventilation and intubation: TMJA and adenotonsillar hypertrophy. These difficulties were anticipated and managed accordingly. The accidental extubation brought to our attention the fact that, even after surgical correction, this airway remains challenging. Even with intensive jaw stretchingexercises there is a high incidence of re-ankylosis, especially in younger patients. One should bear that in mind when anaesthetizing patients with TMJA.

Utilização do Sugamadex: da Evidência à Prática Clínica

O bloqueio neuromuscular (BNM) residual é um fenómeno frequente em doentes cirúrgicos após administração de relaxantes musculares. Está associado a um aumento da morbilidade e mortalidade pós-operatória devido às complicações clínicas dos eventos associados. O sugamadex é um novo fármaco para reversão do BNM induzido por rocurónio ou vecurónio. Como primeiro agente selectivo de ligação aos relaxantes musculares, é promissor em termos de eficácia e perfil de segurança. Apresenta um perfil de eficácia e segurança significativamente diferente ao verificado actualmente com as opções farmacológicas disponíveis. É expectável um valor terapêutico acrescentado significativo sobre estas mesmas opções, com importantes alterações na prática clínica anestésica e cirúrgica, com ganhos para os doentes, para os médicos e para o próprio hospital. Baseados na literatura e na experiência clínica, os autores partilham as suas reflexões relativas ao uso de sugamadex. Apresentam uma proposta para a sua utilização na prática clínica corrente, de acordo com as indicações do RCM, características dos doentes e situações clínicas específicas.

Hiperlordose Lombar

Objectivos: Pretendeu-se fazer uma revisão da literatura disponível sobre hiperlordose lombar: apresentar uma definição, abordar a etiopatogenia, o diagnóstico e enunciar a classificação etiológica, descrevendo para cada forma as suas particularidades, fisiopatologia, clínica e tratamento, incidindo na reabilitação. Material e Métodos: Foram pesquisados livros de texto de referência de Medicina Física e de Reabilitação (MFR) e artigos de bases de dados electrónicas, utilizando os termos “hiperlordose lombar”, “hiperlordose”, “lordose lombar” e “lordose”. Limitou-se a procura a artigos de revisão publicados na língua inglesa ou francesa, em que o termo utilizado constasse no título, resumo e/ou palavras-chave e em que estivesse disponível o resumo e o artigo completo. Após a selecção de informação, o suporte bibliográfico constou em 4 capítulos de livros de texto e 40 artigos científicos. Resultados: A lordose lombar é uma curva no plano sagital da coluna lombar com vértice anterior, que pode ser medida na radiografia de perfil, utilizando o método de Cobb. A Scoliosis Research Society (SRS) estipulou como ângulos fisiológicos o intervalo entre 31º e 79º. O diagnóstico de hiperlordose lombar é estabelecido quando se identifica uma curva com um ângulo superior ao fisiológico. Esta patologia é mais frequentemente assintomática, embora se possa manifestar por lombalgia e diminuição da flexibilidade da coluna lombar. De acordo com a SRS, pode ser classificada em postural (forma mais frequente), congénita (devido a anomalias do desenvolvimento embrionário vertebral), pós-laminectomia (iatrogénica), neuromuscular (resultando de desequilíbrios do tónus e da força muscular), secundária a contractura em flexão da anca e associada a outras causas. As formas associadas a espondilólise (frequente em adolescentes que praticam desportos que envolvem hiperextensão lombar repetitiva) e espondilolistese (atribuível a múltiplas etiologias) foram incluídas na classificação por vários autores. A abordagem da MFR no tratamento da hiperlordose lombar pode envolver medidas gerais, cinesiterapia e utilização de ortóteses; alguns casos têm indicação cirúrgica. Conclusões: A hiperlordose lombar é uma alteração estática da coluna de diagnóstico simples, assente no exame físico e confirmação radiológica. A intervenção da MFR tem um papel preponderante na detecção desta patologia e no benefício das suas opções terapêuticas, visando a melhoria da qualidade de vida dos doentes.

Caracterização da Utilização de Sugamadex no Centro Hospitalar de Lisboa Central - Hospital de S. José

Introdução O sugamadex é uma gama ciclodextrina modificada que forma um complexo com os bloqueadores neuromusculares rocurónio e vecurónio, revertendo o bloqueio neuromuscular (BNM) induzido por estes fármacos1,2,3,4. O sugamadex apresentou valor terapêutico acrescentado em relação aos anticolinesterásicos, nomeadamente à neostigmina, para a reversão do BNM causado pelo rocurónio e vecurónio1,3. No Hospital de São José (HSJ) este medicamento foi introduzido em Outubro de 2010 para a reversão do BNM profundo e nas situações de risco de vida imediato associadas a via aérea difícil com impossibilidade de ventilar e de entubar. A dispensa do sugamadex é efectuada por reposição de stock mediante envio de justificação clínica aos Serviços Farmacêuticos (SF). Objetivo Caracterizar a utilização de sugamadex no HSJ: evolução do consumo, serviços clínicos utilizadores e adequação da utilização clínica face às indicações aprovadas pela Comissão de Farmácia e Terapêutica (CFT). Métodos Pesquisa e análise bibliográfica. Recolha, através da do sistema de gestão integrada do circuito do medicamento, dos dados de consumo desde Outubro de 2010 até Junho de 2015, por semestre e por serviço clínico. Recolha das indicações terapêuticas em que o sugamadex foi administrado, no período acima referido, através da consulta das justificações clínicas. Análise retrospectiva dos dados recolhidos. Resultados Apresentação gráfica dos consumos de sugamadex nos serviços utilizadores no período em estudo. Apresentação gráfica das indicações terapêuticas em que foi administrado, por serviço e no período em estudo. Conclusões O consumo de sugamadex tem um evidente crescimento desde o seu início de utilização. A justificação dominante para a utilização do sugamadex é a curarização residual. Verifica-se um alargamento do âmbito de utilização, face às indicações aprovadas pela CFT.
