Abstract Background Postoperative cough may occur after tracheal intubation, but it is indistinct which drug is best at diminishing these events. Additionally, airway reflexes are commonly accompanied by severe hemodynamics responses during emergence. Objectives To evaluate the role of topical airway anesthesia on immediate post-extubation cough/bucking and extubation time. Methods Randomized clinical trials from MEDLINE, EMBASE, CENTRAL, and LILACS published until December 23, 2020 were included. Our primary outcome was postoperative cough/bucking incidence which was compared between local anesthetics and controls. Extubation times were likewise considered. Predisposition appraisal and subgroup, affectability investigations were likewise performed. Results The pooled analysis found a 45% reduction in cough incidence after treatment with topical airway local anesthetic (RR = 0.55; 95% CI: 0.42 to 0.72; p< 0.001). The number needed to treat (NNT) was 4.61. The intervention showed no differences in reduction of the extubation time (mean difference = -0.07; 95% CI: -0.14 to 0.28; p= 0.49). Conclusion Topical airway anesthesia demonstrated better than placebo or no medication in reducing immediate post-extubation cough/bucking. Further studies could have this objective to combine the different ways to perform better outcomes for patients. intubation events Additionally emergence postextubation post coughbucking bucking MEDLINE EMBASE CENTRAL 23 202 included controls considered subgroup performed 45 RR 0.55 055 0 55 95 CI 042 42 0.4 0.72 072 72 p 0.001. 0001 0.001 . 001 0.001) NNT (NNT 461 4 61 4.61 mean 0.07 007 07 -0.07 0.14 014 14 -0.1 0.28 028 28 0.49. 049 0.49 49 0.49) patients 2 20 0.5 05 5 9 04 0. 0.7 7 000 0.00 00 46 6 4.6 0.0 -0.0 0.1 01 1 -0. 0.2 02 4. -0 -

OBJECTIVES: The current study compared the impact of pretreatment with melatonin and N-acetylcysteine (NAC) on the prevention of rat lung damage following intestinal ischemia-reperfusion (iIR). METHODS: Twenty-eight Wistar rats were subjected to intestinal ischemia induced by a 60 min occlusion of the superior mesenteric artery, followed by reperfusion for 120 min. Animals were divided into the following groups (n=7 per group): sham, only abdominal incision; SS+iIR, pretreated with saline solution and iIR; NAC+iIR, pretreated with NAC (20 mg/kg) and iIR; MEL+iIR, pretreated with melatonin (20 mg/kg) and iIR. Oxidative stress and inflammatory mediators were measured and histological analyses were performed in the lung tissues. RESULTS: Data showed a reduction in malondialdehyde (MDA), myeloperoxidase (MPO), and TNF-alpha in the animals pretreated with NAC or MEL when compared to those treated with SS+iIR (p<0.05). An increase in superoxide dismutase (SOD) levels in the NAC- and MEL-pretreated animals as compared to the SS+iIR group (34±8 U/g of tissue; p<0.05) was also observed. TNF-α levels were lower in the MEL+iIR group (91±5 pg/mL) than in the NAC+iIR group (101±6 pg/mL). Histological analysis demonstrated a higher lung lesion score in the SS+iIR group than in the pretreated groups. CONCLUSION: Both agents individually provided tissue protective effect against intestinal IR-induced lung injury, but melatonin was more effective in ameliorating the parameters analyzed in this study.

Resumo Introdução: A Organização Mundial da Saúde (OMS) tem recomendado uma maior atenção com a segurança do paciente, mais especificamente em relação aos eventos adversos evitáveis. Foi lançado o programa “Cirurgia Segura Salva Vidas (CSSV)”, que recomenda a aplicação da lista de verificação cirúrgica (checklist) para a conferência de itens relacionados à segurança do procedimento. A implantação do checklist reduziu a mortalidade hospitalar nos primeiros 30 dias. No Brasil, não foram identificados estudos sobre adesão dos anestesiologistas à prática do checklist. Objetivo: Desenvolvimento de uma ferramenta para mensuração da atitude dos anestesiologistas e residentes em relação ao uso do checklist no período perioperatório. Método: Estudo transversal feito durante o 59° Congresso Brasileiro de Anestesiologia (CBA), em Belo Horizonte (MG), cujos participantes foram médicos inscritos e que responderam ao questionário com abordagem epidemiológica quantitativa. Resultados: A amostra constou de 459 participantes que responderam ao questionário, 55% do sexo masculino, 44,2% com menos de 10 anos e 15,5% acima de 30 anos de conclusão do curso médico. Foram selecionados sete itens com coeficiente de confiabilidade de 78%. Houve diferença estatisticamente significativa entre os grupos de anestesiologistas que referiram usar o instrumento em menos ou mais de 70% dos pacientes assistidos. Isso indica que o questionário de atitudes discrimina entre esses dois grupos de profissionais. Conclusões: O questionário de sete itens mostrou adequada consistência interna e uma estrutura fatorial bem delimitada. Pode ser usado como ferramenta para medida das percepções de anestesiologistas quanto à utilidade e a aplicabilidade do checklist.

Abstract Background: The World Health Organization (WHO) has recommended greater attention to patient safety, particularly regarding preventable adverse events. The Safe Surgery Saves Lives (CSSV) program was released recommending the application of a surgical checklist for items on the safety of procedures. The checklist implementation reduced the hospital mortality rate in the first 30 days. In Brazil, we found no studies of anesthesiologists’ adherence to the practice of the checklist. Objective: The main objective was to develop a tool to measure the attitude of anesthesiologists and residents regarding the use of checklist in the perioperative period. Method: This was a cross-sectional study performed during the 59th CBA in BH/MG, whose participants were enrolled physicians who responded to the questionnaire with quantitative epidemiological approach. Results: From the sample of 459 participants who answered the questionnaire, 55% were male, 44.2% under 10 years of practice, and 15.5% with over 30 years of medical school completion. Seven items with 78% reliability coefficient were selected. There was a statistically significant difference between the groups of anesthesiologists who reported using the instrument in less or more than 70% of patients, indicating that the attitude questionnaire discriminates between these two groups of professionals. Conclusions: The seven items questionnaire showed adequate internal consistency and a well-defined factor structure, and can be used as a tool to measure the anesthesiologists’ perceptions about the checklist usefulness and applicability.
