Difficult laryngoscopy and tracheal intubation: observational study

Introduction: Since anesthesia complications associated with unexpected difficult airway are potentially catastrophic, they should be avoided. The modified Mallampati test and jaw-thrust maneuver enable the identification of difficult airway. The aim of this study was to associate the modified Mallampati test and the jaw-thrust maneuver with laryngoscopy (Cormack–Lehane) in an attempt to identify a better predictor of difficult airway in an adult population undergoing elective surgery. Method: A cross-sectional study in which 133 adult patients undergoing elective surgery requiring tracheal intubation were analyzed. The accuracy and specificity of the modified Mallampati test and jaw-thrust maneuver were assessed by correlating them with difficult laryngoscopy (Cormack–Lehane Degrees 3 and 4). Results: In the 133 patients evaluated the difficult intubation rate found was 0.8%; there was association between the two predictive tests proposed (p = 0.012). The values of 94.5% for specificity and 95.4% for accuracy were found for the jaw-thrust maneuver and for the modified Mallampati test, the values found were 81.1% and 81.2%, respectively. Kappa agreement identified a result of 0.240 between jaw-thrust maneuver and Cormack–Lehane, which was considered reasonable. On the other hand, a poor agreement (κ = 0.06) was seen between modified Mallampati test and Cormack–Lehane test. Conclusion: The jaw-thrust maneuver presented superior accuracy and agreement than the modified Mallampati test, showing the ability to identify a difficult airway. It is necessary to emphasize the association of tests in the evaluation of patients, emphasizing their complementarity to minimize the negative consequences of repeated laryngoscopies. Resumo: Introdução: As complicações anestésicas associadas às vias aéreas difíceis inesperadas por serem potencialmente catastróficas devem ser evitadas. O teste de Mallampati modificado e a manobra de protrusão mandibular possibilitam a identificação da via aérea difícil. O objetivo deste estudo foi associar o teste de Mallampati modificado e a manobra de protrusão mandibular com a laringoscopia (Cormack-Lehane) e tentar identificar um melhor preditor de via aérea difícil na população adulta submetida à cirurgia eletiva. Método: Estudo corte transversal, foram analisados 133 pacientes adultos submetidos a cirurgias eletivas que necessitavam de intubação orotraqueal. Avaliaram-se a acurácia e especificidade do teste de Mallampati modificado e da manobra de protrusão mandibular, correlacionados com laringoscopia difícil (Cormack-Lehane Graus 3 e 4). Resultados: Entre os 133 pacientes avaliados, a taxa de intubação difícil encontrada foi 0,8%, houve associação entre os dois testes preditores propostos (p = 0,012). Foram encontrados os seguintes valores para a especificidade 94,5% e a acurácia 95,4% na manobra de protrusão mandibular. Já para o teste de Mallampati modificado valores de 81,1% e de 81,2% respectivamente. A análise de concordância Kappa identificou entre manobra de protrusão mandibular e Cormarck-Lehane um resultado de 0,240; considerado razoável. Por outro lado, observou-se uma fraca (κ = 0,06) concordância entre o teste de Mallampati modificado e o Cormarck-Lehane. Conclusão: A manobra de protrusão mandibular apresentou acurácia e concordância superiores ao teste de Mallampati modificado, mostrou a capacidade de identificar uma via aérea difícil. Faz-se necessário enfatizar a associação dos testes na avaliação do paciente, destacar a complementariedade deles, minimizar as consequências negativas de laringoscopias repetidas.

Association of Pain Catastrophizing with the Incidence and Severity of Acute and Persistent Perineal Pain after Natural Childbirth: Longitudinal Cohort Study

AbstractBackground and objectives Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma.Method Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the first 24hours and after 8 weeks of delivery using a numerical pain scale.Results We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 ± 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33).Conclusions The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain

Este estudo avaliou a associação da catastrofização, fenômeno de má adaptação psicológica à dor que leva o indivíduo a magnificar a experiência dolorosa, tornando-a mais intensa, com a incidência e a intensidade da dor perineal e sua relação com o trauma perineal. MÉTODO: Estudo coorte. Realizado com gestantes em trabalho de parto. Foi aplicada a escala de pensamentos catastróficos sobre a dor durante o internamento e foram avaliados o grau da lesão perineal e a intensidade da dor perineal nas primeiras 24 horas e após oito semanas do parto por meio da escala numérica de dor. RESULTADOS: Avaliadas 55 mulheres. Sentiram dor aguda 69,1% das pacientes. Dessas, 36,3% queixaram-se de dor de moderada/forte intensidade e 14,5% de dor persistente. O escore médio de catastrofização foi de 2,15 ± 1,24. As pacientes catastrofizadoras apresentaram um risco 2,90 vezes maior (95% IC: 1,08-7,75) de apresentar dor perineal aguda e 1,31 vezes maior (95% IC: 1,05-1,64) de desenvolver dor perineal persistente. Também apresentaram um risco 2,2 vezes maior de desenvolver dor perineal aguda de maior intensidade (95% IC: 1,11-4,33). CONCLUSÕES: A incidência de dor perineal aguda e persistente após parto vaginal é alta. Gestantes catastrofizadoras apresentam maior risco de desenvolver dor perineal aguda e persistente, como também dor de maior intensidade. O trauma perineal aumentou o risco de ocorrência de dor perineal persistente.JUSTIFICATIVA Y OBJETIVOS: El parto vaginal puede traer dolor perineal agudo y persistente postparto.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
