Evolving Indications for Heart-Lung Transplant in Spain.

BACKGROUND: The outcomes of heart-lung transplant (HLT) are worse than those of heart transplant (HT) and lung transplant alone; this and the availability of mechanical assistance have meant that the indications for HLT have been changing. This study aims to analyze the evolution of indications for HLT in a country of 47 million inhabitants. METHODS: We performed a retrospective observational study of all HLTs performed in Spain (performed in 2 centers) from 1990 to 2020. The total number of patients included was 1751 (HT 1673 and HLT 78). After clinical adjustment, overall survival was compared between the 2 groups. Seven etiological subgroups were considered within the HLT group: (1) cardiomyopathy with pulmonary hypertension (CM + PH);, (2) Eisenmenger syndrome, (3) congenital heart disease without Eisenmenger syndrome, (4) idiopathic pulmonary arterial hypertension (IPAH), (5) cystic fibrosis, (6) chronic obstructive pulmonary disease (COPD) and/or emphysema), and (7) diffuse interstitial lung disease. RESULTS: There were a large number of differences between patients with HLT vs HT. HLT had a 2.69-fold increased probability of death in the first year compared with HT. The indications for HLT have changed over the years. In the recent period the indications are mainly congenital heart disease and Eisenmenger syndrome, with some cases of CM + PH. Other indications for HLT have virtually disappeared, mainly lung diseases (IPAH, COPD, cystic fibrosis). Median survival was low in CM + PH (18 days), diffuse interstitial lung disease (29 days), and ischemic heart disease (114 days); intermediate in Eisenmenger syndrome (600 days); and longer in IPAH, COPD and/or emphysema, and cystic fibrosis. CONCLUSIONS: HLT is a procedure with high mortality. This and mechanical assists mean that the indications have changed over the years. Etiological analysis is of utmost interest to take advantage of organs and improve survival.

Encuesta sobre la anestesiología en cirugía vascular e impacto de la pandemia por la COVID-19 / Survey on anesthesiology in vascular surgery and COVID-19 pandemic impact

Los pacientes sometidos a cirugía vascular son pluripatológicos y complejos. En los últimos años ha habido un incremento importante en el número de pacientes intervenidos por vía endovascular. La Sección de Anestesiología Cardíaca, Vascular y Torácica de la Sociedad Española de Anestesiología y Reanimación (SEDAR) diseñó una encuesta telemática basada en 29 preguntas mediante Google Forms® que envió a todos sus miembros. Un total de 204 anestesiólogos contestaron una serie de preguntas estructuradas en bloques: 1. Cirugía de la endarterectomía carotídea; 2. Reparación de aneurisma de aorta abdominal y torácica; 3. Cirugía arterial y venosa de miembros inferiores; 4. Impacto de la pandemia por la COVID-19 sobre la programación quirúrgica en cirugía vascular; 5. Programas de recuperación intensificada en cirugía vascular, y 6. Otras preguntas. A pesar de determinadas diferencias en cuanto al manejo anestésico, la anestesia locorregional es una técnica ampliamente utilizada. Los tres determinantes para la actuación del anestesiólogo son el paciente, su patología y la idiosincrasia de cada centro. Actualmente, los programas de recuperación acelerada en cirugía vascular no están ampliamente implementados en España. Finalmente, los resultados ponen de manifiesto que, durante la primera ola de la pandemia por la COVID-19, la cirugía vascular quedó prácticamente reducida a la cirugía urgente y emergente, según las recomendaciones anestésicas y quirúrgicas de las diferentes sociedades científicas, incluidas la SEDAR y la SEACV.(AU)

Patients undergoing vascular surgery are multi-pathological and complex. In recent years there has been a significant increase in the number of patients undergoing endovascular surgery. The Cardiac, Vascular and Thoracic section of the Spanish Society of Anesthesiology and Resuscitation (SEDAR) designed a telematic survey based on 29 questions using Google Forms® that was sent to all members of this society. A total of 204 anesthesiologists answered questions structured in blocks: 1. Carotid endarterectomy; 2. Abdominal and thoracic aortic aneurysm repair; 3. Lower limb arterial and venous surgery; 4. Impact of the COVID-19 pandemic on vascular surgical scheduling; 5. Enhanced recovery after vascular surgery; 6. Other questions. Despite certain differences in anesthetic management, locoregional anesthesia is a widely used technique. The three determinants for the anesthesiologist’s performance are the patient, his or her pathology and the idiosyncrasy of each center. Currently, accelerated recovery programs in vascular surgery are not widely implemented in Spain. Finally, the results show that during the first wave of the COVID-19 pandemic, vascular surgery was practically reduced to urgent and emergent surgery, following the anesthetic and surgical recommendations of the different scientific societies, including SEDAR and SEACV.(AU)

Pharmacokinetics of micafungin in patients treated with extracorporeal membrane oxygenation: an observational prospective study. / Farmacocinética da micafungina em pacientes tratados com oxigenação por membrana extracorpórea: um estudo observacional prospectivo.

OBJECTIVE: To determine micafungin plasma levels and pharmacokinetic behavior in patients treated with extracorporeal membrane oxygenation. METHODS: The samples were taken through an access point before and after the membrane in two tertiary hospitals in Spain. The times for the calculation of pharmacokinetic curves were before the administration of the drug and 1, 3, 5, 8, 18 and 24 hours after the beginning of the infusion on days one and four. The area under the curve, drug clearance, volume of distribution and plasma half-life time with a noncompartmental pharmacokinetic data analysis were calculated. RESULTS: The pharmacokinetics of the values analyzed on the first and fourth day of treatment did not show any concentration difference between the samples taken before the membrane (Cin) and those taken after the membrane (Cout), and the pharmacokinetic behavior was similar with different organ failures. The area under the curve (AUC) before the membrane on day 1 was 62.1 (95%CI 52.8 - 73.4) and the AUC after the membrane on this day was 63.4 (95%CI 52.4 - 76.7), p = 0.625. The AUC before the membrane on day 4 was 102.4 (95%CI 84.7 - 142.8) and the AUC was 100.9 (95%CI 78.2 - 138.8), p = 0.843. CONCLUSION: The pharmacokinetic parameters of micafungin were not significantly altered.

Farmacocinética da micafungina em pacientes tratados com oxigenação por membrana extracorpórea: um estudo observacional prospectivo / Pharmacokinetics of micafungin in patients treated with extracorporeal membrane oxygenation: an observational prospective study

RESUMO Objetivo: Determinar os níveis plasmáticos e o comportamento farmacocinético da micafungina em pacientes tratados com oxigenação por membrana extracorpórea. Métodos: As amostras foram colhidas por meio de pontos de acesso antes e depois da membrana, em dois hospitais espanhóis de nível terciário. Os momentos para o cálculo das curvas farmacocinéticas foram antes da administração do fármaco, e 1, 3, 5, 8, 18 e 24 horas após o início da infusão nos dias 1 e 4 de tratamento. Calcularam-se a área sob a curva, a depuração do fármaco, o volume de distribuição e a meia-vida plasmática por meio de análise farmacocinética não compartimental. Resultados: Os valores farmacocinéticos analisados no primeiro e quarto dias de tratamento não mostram qualquer diferença de concentração entre amostras colhidas antes da membrana e após a membrana, e o comportamento farmacocinético foi similar na vigência de diferentes falências de órgãos. A área sob a curva antes da membrana no dia 1 foi de 62,1 (IC95% 52,8 - 73,4) e a área sob a curva após a membrana nesse mesmo dia foi de 63,4 (IC95% 52,4 - 76,7), com p = 0,625. A área sob a curva antes da membrana no dia 4 foi de 102,4 (IC95% 84,7 - 142,8), enquanto a área sob a curva após a membrana nesse mesmo dia foi de 100,9 (IC95% 78,2 - 138,8), com p = 0,843. Conclusão: Os parâmetros farmacocinéticos da micafungina não foram alterados significantemente.

[Lung transplantation for emphysema: retrospective study of 65 patients]. / Trasplante pulmonar por enfisema: análisis retrospectivo de 65 pacientes.

BACKGROUND AND OBJECTIVE: Our goal was to analyze the incidence of perioperative complications in patients with pulmonary emphysema who underwent lung transplantation and to identify variables associated with the incidence of morbidity and mortality during the immediate postoperative period. PATIENTS AND METHOD: We undertook a retrospective study of 65 pulmonary emphysema patients who received lung transplants from 1994 through 2002 with the aim of determining the most common intra- and early postoperative complications in the ICU. An univariate analysis was carried out in order to identify variables associated with the incidence of mortality and postoperative complications. Those variables showing statistical significance underwent a multivariate analysis, by means of a pattern of logistic regression, in order to calculate the odds ratio and confidence interval. RESULTS: Seventeen patients received single-lung transplants (SLT) and 48 patients received sequential double-lung transplants (DLT). Intraoperative complications appeared more frequently in the DLT group. Most frequent complications during surgery were reperfusion syndrome (44.6%) and pulmonary hypertension (16.9%). The intraoperative survival was 100%. Fifty-five patients had some type of postoperative complication. Commonest postoperative complications were infection (56.9%) and primary graft failure (36.6%). In the early postoperative period the mortality rate was 16.9%. Main cause of death in the ICU was sepsis (54.5%). A time of mechanical ventilation > 48 hours and postoperative hemorrhage were the variables with a higher predictive value for mortality in the early postoperative period. CONCLUSIONS: Patients with SLT had a lower rate of perioperative complications and a higher survival during their stay in the ICU. Time of mechanical ventilation > 48 hours and postoperative hemorrhage were the variables that best predicted death in the early postoperative period following lung transplantation. Despite our experience, however, perioperative mortality in lung transplantation remains high up to this day.

Trasplante pulmonar por enfisema: análisis retrospectivo de 65 pacientes / Lung transplantation for emphysema: retrospective study of 65 patients

Fundamento y objetivo: Describir la incidencia de complicaciones perioperatorias de los pacientes trasplantados de pulmón por enfisema pulmonar y estudiar los factores de riesgo asociados a la morbimortalidad en el postoperatorio inmediato. Pacientes y método: Estudio retrospectivo que incluye a 69 pacientes trasplantados de pulmón por enfisema pulmonar durante los años 1994-2002. Se realizó un análisis univariante para identificar las variables asociadas con la incidencia de la mortalidad en la Unidad de Reanimación o con el aumento de complicaciones postoperatorias. Las variables que presentaron significación estadística se sometieron a análisis multivariante mediante el modelo de regresión logística. Resultados: Se incluyó a 65 pacientes. Diecisiete recibieron un trasplante unipulmonar (TUP) y 48 un transplante bilateral secuencial (TBP). Las complicaciones intraoperatorias fueron más habituales en el grupo del trasplante bipulmonar (35,3% en el TBP frente a 72,9% en el TUP, p < 0,006), y las complicaciones intraoperatorias más frecuentes fueron el síndrome posreperfusión y la hipertensión pulmonar . No hubo ningún caso de mortalidad intraoperatoria en la serie. Las complicaciones postoperatorias más frecuentes fueron la infección (56,9%) y el fallo primario del injerto (36,6%). Cincuenta y cinco pacientes presentaron alguna complicación en el postoperatorio inmediato. La mortalidad global en el postoperatorio fue del 16,9%, y que la sepsis (54,5%) la causa más frecuente de fallecimiento en el postoperatorio inmediato. La ventilación mecánica durante más de 48 h y la hemorragia posquirúrgica fueron las variables con mayor valor predictivo de mortalidad en el postoperatorio Conclusiones: Los pacientes con TUP tienen menor número de complicaciones en el perioperatorio, lo que condiciona una mayor supervivencia durante la estancia en reanimación. La ventilación mecánica durante más de 48 h y la hemorragia posquirúrgica fueron las variables que mejor predijeron la mortalidad en el postoperatorio inmediato
