Manejo anestésico versus seguridad del paciente en tiempos de COVID-19 / Anesthetic management vs patient safety in times of COVID-19

Resumen: La pandemia del COVID-19 ha tenido un impacto significativo en los servicios sanitarios de todo el mundo. Desde el punto de vista anestésico, algunos de los retos clínicos son el alto riesgo del paciente de sufrir complicaciones pulmonares durante el período perioperatorio y el de infección del personal sanitario por la manipulación de la vía aérea y los aerosoles. Se describe la conducta anestésica realizada a una paciente oncológica con PCR para COVID-19 positiva que deseaba preservar su fertilidad antes de comenzar tratamiento oncológico adyuvante y que, según los protocolos establecidos en el momento del caso, se debían demorar las intervenciones no urgentes hasta la negativización de la PCR, lo que conllevaría a retrasar la intervención sin poder comenzar el tratamiento médico para el proceso tumoral, escogiéndose la técnica anestésica más fiable para evitar complicaciones a la paciente y al personal sanitario.

Abstract: The COVID-19 pandemic has had a significant impact on healthcare services worldwide. From the anesthetic point of view, some of the clinical challenges are the high patient risk of pulmonary complications during the perioperative period and the risk of infection of healthcare personnel due to airway and aerosol handling. We describe the anesthetic management of an oncological patient with positive PCR for COVID-19 who wished to preserve her fertility before starting adjuvant oncological treatment and that, according to the protocols established at the time of the case, non-urgent interventions should be delayed until the PCR was negative, which would lead to delaying the intervention without being able to start medical treatment for the tumor process, choosing the most reliable anesthetic technique to avoid complications for the patient and the health personnel.

Analgesia obstétrica en la paciente con síndrome de Stickler: un reporte de caso y revisión de la literatura / Obstetric analgesia in the patient with Stickler syndrome: a case report and review of the literature

Resumen: El síndrome de Stickler tiene una incidencia de uno en 7,500-9,000 recién nacidos. Es una enfermedad del tejido conectivo con patrón de herencia autosómico dominante en la mayoría de los casos, aunque también con patrón recesivo, por afección patogénica de genes procolágeno como COL2A1, COL11A1, entre otros. Cursa con manifestaciones multisistémicas craneofaciales, oculares, auditivas, esqueléticas/articulares y se ha asociado a prolapso de la válvula mitral. Se diferencian tres tipos: tipo I (el más frecuente, 75%) o síndrome de Stickler completo, tipo II o síndrome de Stickler ocular y el tipo III u oto-espóndilo-displasia megaepifisaria. El diagnóstico se realiza al probar las manifestaciones o al demostrar una variante genética patogénica. Respecto al manejo anestésico en la paciente obstétrica, se recomienda evitar la anestesia general. Se presenta el caso de una paciente de 26 años con diagnóstico de síndrome de Stickler tipo I, con embarazo a término y su relación con la anestesia neuroaxial. A pesar de su incidencia, no existe literatura médica acerca del manejo de la anestesia neuroaxial en este tipo de pacientes.

Abstract: Stickler syndrome has an incidence of 1/7.500-9.000 in newborns. It is a connective tissue disease with an autosomal dominant inheritance pattern in most cases, but also with a recessive pattern, due to the pathogenic involvement of procollagen genes such as COL2A1, COL11A1, among others. It is characterized by craniofacial, ocular, auditory and skeletal/joint multisystemic signs and symptoms, and has been associated with prolapse of the mitral valve. Three types are differentiated: type I (the most frequent, 75%) or complete Stickler syndrome, type II or ocular Stickler syndrome and type III or oto-espondilo-megaepiphyseal dysplasia. The diagnosis is made by confirming the signs and symptoms or by verifying the presence of a pathogenic genetic variant. With respect to the anesthetic management in the obstetric patient, it is recommended to avoid general anesthesia. The article illustrates the case of a female patient of 26 years with Stickler syndrome type I and full-term pregnancy, and associated implications for neuroaxial anesthesia. Despite its incidence, there is no medical literature on the management of neuraxial anesthesia in this type of patients.

Neuraxial anesthesia in patients with multiple sclerosis - a systematic review / Anestesia neuraxial em pacientes com esclerose múltipla - uma revisão sistemática

Abstract Background and objectives: Current guidelines for neuraxial analgesia in patients with multiple sclerosis are ambiguous and offer the clinician only a limited basis for decision making. This systematic review examines the number of cases in which multiple sclerosis has been exacerbated after central neuraxial analgesia in order to rationally evaluate the safety of these procedures. Methods: A systematic literature search with the keywords "anesthesia or analgesia" and "epidural, peridural, caudal, spinal, subarachnoid or intrathecal" in combination with "multiple sclerosis" was performed in the databases PubMed and Embase, looking for clinical data on the effect of central neuraxial analgesia on the course of multiple sclerosis. Results and conclusions: Over a period of 65 years, our search resulted in 37 reports with a total of 231 patients. In 10 patients multiple sclerosis was worsened and nine multiple sclerosis or neuromyelitis optica was first diagnosed in a timely context with central neuraxial analgesia. None of the cases showed a clear relation between cause and effect. Current clinical evidence does not support the theory that central neuraxial analgesia negatively affects the course of multiple sclerosis.

Resumo Justificativa e objetivos: As diretrizes atuais para analgesia neuraxial em pacientes com esclerose múltipla (EM) são ambíguas e oferecem ao clínico apenas uma base limitada para a tomada de decisão. Esta revisão sistemática examina o número de casos nos quais a EM foi exacerbada após analgesia neuraxial central para avaliar racionalmente a segurança desses procedimentos. Métodos: Uma busca sistemática da literatura com as palavras-chave "anestesia ou analgesia" e "epidural, peridural, caudal, espinhal, subaracnóideo ou intratecal" em combinação com multiple sclerosis foi feita nas bases de dados PubMed e Embase à procura de dados clínicos sobre a efeito da analgesia neuraxial central sobre o curso da esclerose múltipla. Resultados e conclusões: Durante um período de 65 anos, nossa busca resultou em 37 relatos com um total de 231 pacientes. Em 10 pacientes, a esclerose múltipla foi agravada e, em nove, a esclerose múltipla ou neuromielite óptica foi diagnosticada pela primeira vez em momento concomitante com a analgesia neuraxial central. Nenhum dos casos apresentou uma clara relação entre causa e efeito. A evidência clínica atual não sustenta a teoria de que a analgesia neuraxial central afeta negativamente o curso da esclerose múltipla.

Pain after major elective orthopedic surgery of the lower limb and type of anesthesia: does it matter? / Dor após cirurgia eletiva ortopédica de grande porte em membro inferior e o tipo de anestesia: isso importa?

Abstract Background and objectives: Total knee arthroplasty and total hip arthroplasty are associated with chronic pain development. Of the studies focusing on perioperative factors for chronic pain, few have focused on the differences that might arise from the anesthesia type performed during surgery. Methods: This was a prospective observational study performed between July 2014 and March 2015 with patients undergoing unilateral elective total knee arthroplasty (TKA) or total hip arthroplasty (THA) for osteoarthritis. Data collection and pain evaluation questionnaires were performed in three different moments: preoperatively, 24 hours postoperatively and at 6 months after surgery. To characterize pain, Brief Pain Inventory (BPI) was used and SF-12v2 Health survey was used to further evaluate the sample's health status. Results: Forty and three patients were enrolled: 25.6% men and 74.4% women, 51,2% for total knee arthroplasty and48.8% for total hip arthroplasty, with a mean age of 68 years. Surgeries were performed in 25.6% of patients under general anesthesia, 55.8% under neuraxial anesthesia and 18.6% under combined anesthesia. Postoperatively, neuraxial anesthesia had a better pain control. Comparing pain evolution between anesthesia groups, neuraxial anesthesia was associated with a decrease in “worst”, “medium” and “now” pain at six months. Combined anesthesia was associated with a decrease of “medium” pain scores at six months. Of the three groups, only those in neuraxial group showed a decrease in level of pain interference in “walking ability”. TKA, “worst” pain preoperatively and general were predictors of pain development at six months. Conclusions: Patients with gonarthrosis and severe pain preoperatively may benefit from individualized pre- and intraoperative care, particularly preoperative analgesia and neuraxial anesthesia.

Resumo Justificativa e objetivos: A artroplastia total de joelho e a artroplastia total de quadril estão associadas ao desenvolvimento de dor crônica. Dentre os estudos que avaliam os fatores perioperatórios para a dor crônica, poucos abordam as diferenças que podem surgir do tipo de anestesia feita durante a cirurgia. Métodos: Estudo observacional, prospectivo, feito entre julho de 2014 e março 2015 com pacientes submetidos à ATJ unilateral eletiva ou ATQ para a osteoartrite. A coleta de dados e a avaliação da dor por meio de questionários foram feitas em três momentos distintos: no pré-operatório, em 24 horas de pós-operatório e aos seis meses após a cirurgia. O Inventário Breve da Dor (IBD) foi usado para caracterizar a dor o e o Questionário SF-12v2 foi usado para avaliar melhor o estado de saúde da amostra. Resultados: Foram inscritos 43 pacientes: 25,6% homens e 74,4% mulheres, 51,2% para ATJ e 48,8% ATQ, com média de 68 anos. A cirurgia foi feita em 25,6% dos pacientes sob anestesia geral, em 55,8% sob anestesia neuroaxial e em 18,6% sob anestesia combinada. No pós-operatório, a anestesia neuraxial apresentou melhor controle da dor. Na comparação da evolução da dor entre os grupos, a anestesia neuraxial foi associada a uma diminuição de “pior”, “médio” e “sem” dor em seis meses. A anestesia combinada foi associada a uma diminuição do escore “médio” de dor em seis meses. Dos três grupos, apenas aqueles no grupo neuraxial apresentaram uma diminuição do nível de interferência da dor na “capacidade de caminhar”. ATJ, “pior” dor no pré-operatório e anestesia geral foram preditivos de desenvolvimento de dor aos seis meses. Conclusões: Os pacientes com gonartrose e dor intensa no pré-operatório podem obter benefício de cuidados individualizados no pré e intraoperatório, particularmente de analgesia no pré-operatório e anestesia neuraxial.

Effectiveness of combined regional-general anesthesia for reducing mortality in coronary artery bypass: meta-analysis / Efetividade da associação da anestesia regional à anestesia geral na redução da mortalidade em revascularização miocárdica: metanálise

ABSTRACT BACKGROUND AND OBJECTIVES: Neuraxial anesthesia (NA) has been used in association with general anesthesia (GA) for coronary artery bypass; however, anticoagulation during surgery makes us question the viability of benefits by the risk of epidural hematoma. The aim of this study was to perform a meta-analyzes examining the efficacy of NA associated with GA compared to GA alone for coronary artery bypass on mortality reduction. METHODS: Mortality, arrhythmias, cerebrovascular accident (CVA), myocardial infarction (MI), length of hospital stay (LHS), length of ICU stay (ICUS), reoperations, blood transfusion (BT), quality of life, satisfaction degree, and postoperative cognitive dysfunction were analyzed. The weighted mean difference (MD) was estimated for continuous variables, and relative risk (RR) and risk difference (RD) for categorical variables. RESULTS: 17 original articles analyzed. Meta-analysis of mortality (RD = -0.01, 95% CI = -0.03 to 0.01), CVA (RR = 0.79, 95% CI = 0.32-1.95), MI (RR = 0.96, 95% CI = 0.52-1.79) and LHS (MD = -1.94, 95% CI = -3.99 to 0.12) were not statistically significant. Arrhythmia was less frequent with NA (RR = 0.68, 95% CI = 0.50-0.93). ICUS was lower in NA (MD = -2.09, 95% CI = -2.92 to -1.26). CONCLUSION: There was no significant difference in mortality. Combined NA and GA showed lower incidence of arrhythmias and lower ICUS.

RESUMO INTRODUÇÃO E OBJETIVOS: A anestesia neuroaxial (AN) vem sendo utilizada em associação com a anestesia geral (AG) para revascularização miocárdica, entretanto a anticoagulação durante a cirurgia torna questionável a viabilidade dos benefícios mediante o risco de hematoma de espaço peridural. O objetivo deste estudo foi executar metanálises analisando a efetividade da AN associada à AG comparada à AG isolada para a cirurgia de revascularização miocárdica relativa à redução da mortalidade. MÉTODOS: Foram analisados mortalidade, arritmias, acidente vascular cerebral (AVC), infarto miocárdico (IM), tempo de internação hospitalar (TIH), tempo de internação em unidade de terapia intensiva (TUTI), reoperações, transfusão sanguínea (TS), qualidade de vida, grau de satisfação e disfunção cognitiva pós-opertória. A diferença média (DM) ponderada foi estimada para as variáveis contínuas e risco relativo (RR) e a diferença de risco (DR) para variáveis categóricas. RESULTADOS: Analisados 17 artigos originais. Metanálise da mortalidade (DR = -0,01; IC 95% = -0,03 a 0,01), AVC (RR = 0,79; IC 95% = 0,32 a 1,95), IM (RR = 0,96; IC 95% = 0,52 a 1,79) e TIH (DM = -1,94; IC 95% = -3,99 a 0,12) não demonstraram significância estatística. Arritmia foi menos frequente com AN (RR = 0,68; IC 95% = 0,50 a 0,93). O TUTI foi menor no com AN (DM = -2,09; IC 95% = -2,92 a -1,26). CONCLUSÃO: Não se observaram diferenças estatisticamente significantes quanto a mortalidade. A combinação de AN e AG mostrou menor incidência de arritmias e menor TUTI.

Incidencia de complicaciones en anestesia neuroaxial en el Hospital Maternologico Germán Urquidi / Incidence of neuroaxial anesthesia complicaions at Hospital Maternológico Germán Urquidi

Resumen En nuestro medio no existen datos estadísticos con respecto a las complicaciones de la anestesia neuroaxial, y específicamente en hospitales con residentes en entrenamiento. Durante el año 2007 se realizaron 4.235 (100%) procedimientos quirúrgicos bajo anestesia en el Hospital Materno Infantil Germán Urquidi, de los cuales el 57,87% (2.451) fueron realizados con anestesia neuroaxial. El presente etudio es descriptivo y retrospectivo, en el cual se registró la incidencia de las complicaciones en anestesial neuroaxial, utilizando un muestréo aleatorio durante el periodo de un año. El 38,63 % (1 .635) de las pacientes que recibieron anestesia neuroaxial presentó algún tipo de complicación. Sólo el 1 ,48% (14) tuvo una complicación mayor reportada como punción dural advertida; de las cuales 4 pacientes presentaron cefalea postpunción. Entre las pacientes) con complicaciones menores 96,51% (1.577) de las pacientes cursaron con hipotensión arterial; 8 pacientes tuvieron bloqueos fallidos y en 11 pacientes se presentaron punciones vasculares reportadas. La incidencia de complicaciones en anestesia neuroaxial en el Hospital Maternológico Germán Urquidi se encuentra por debajo de lo reportado en la literatura, pues el ser un Hospital Universitario no constituye un factor adicional de riesgo que aumente las complicaciones, en procedimientos permanentemente supervisados.

Abstract During the year 2007 were carried out 4.235 (1 00%) surgical procedures under it anesthetizes in the Hospital Maternal Infantile Germán Urquidi, ofthose which 57,87% (2.451) they were carried out with regional anesthesia. In our means statistical data don't exist with regard to the complications of the regional anesthesia, and specifically in hospitals with residents in training. By means of a descriptive and retrospective study oftraverse court he/she registered the incidence ofthe complications in regional anesthesia, using a random sampling during the period of one year. 38,63% (1 .635) ofthe patients that received regional anesthesia it presented some complication type. Only the 1 ,48%(14) he/she had a bigger complication reported as perforation noticed dural punction; of which 4 patients presented migraine postpuntion. Among the patients with complications smaller 96,51 % (1 .577) ofthe patients they studied with arterial hypotension; 8 patients had bankrupt blockades and in 11 patients reported vascular puntions was presented. The incidence of complications in regional anesthesia in the Hospital Maternológico Germán Urquidi is below that reported in the literature, because the being an University Hospital doesn't constitute an additional factor of risk that increases the complications, in permanently supervised procedures.
