Patients with AMM with symptoms of respiratory or cardiovascular compression are included in the high-risk group for NMR. The risk of cardiorespiratory collapse can be reduced by performing step-by-step anaesthesia, inducing in a rescue position, maintaining spontaneous ventilation, performing the repositioning test before proceeding with the intervention, performing a muscle relaxation test if NMR is unavoidable. Before performing either test, plan A, B and C must be available to reverse the collapse, clear the obstruction or elevate the mass if necessary.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0045">Conflicts of interest</span><p id="par0145" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflicts of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres1294719" "titulo" => "Abstract" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0005" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1195616" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1294720" "titulo" => "Resumen" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0010" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1195617" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:2 [ "identificador" => "sec0010" "titulo" => "Case report" ] 6 => array:2 [ "identificador" => "sec0015" "titulo" => "Discussion" ] 7 => array:2 [ "identificador" => "sec0020" "titulo" => "Conclusions" ] 8 => array:2 [ "identificador" => "sec0025" "titulo" => "Conflicts of interest" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2019-02-06" "fechaAceptado" => "2019-09-26" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1195616" "palabras" => array:3 [ 0 => "Anterior mediastinal mass" 1 => "Anesthetic management" 2 => "Pediatric patient" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1195617" "palabras" => array:3 [ 0 => "Masa mediastínica anterior" 1 => "Manejo anestésico" 2 => "Paciente pediátrico" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><p id="spar0020" class="elsevierStyleSimplePara elsevierViewall">Complications induced by general anesthesia (GA) and neuromuscular relaxation (NMR) in anterior mediastinal mass (AMM) resection can be serious, especially when there are signs of compression of the airway or large vessels (dyspnea, orthopnea, etc.) (1).
