Práctica actual de la inducción de secuencia rápida en adultos: una encuesta nacional entre anestesiólogos en España / Current practice of rapid sequence induction in adults: a national survey among anesthesiologists in Spain

ANTECEDENTES: La inducción de secuencia rápida (ISR) en adultos ha experimentadcambios en los últimos años debido a los avances farmacológicos y tecnológicos. El objetivo de esta encuesta fue evaluar la práctica actual entre los anestesiólogos españoles. MÉTODOS: Se envió un cuestionario con 31 preguntas referentes a la práctica de la ISR a anestesiólogos de hospitales del Servicio Nacional de Salud de España. Las diferencias en las respuestas relacionadas con el tipo de hospital o experiencia se compararon para todos los datos utilizando el Chi-cuadrado y la prueba exacta de Fisher. RESULTADOS: Aproximadamente el 15,89% de los anestesiólogos españoles participaron en la encuesta (1.002 cuestionarios). Los resultados muestran una gran heterogeneidad en la mayoría de los aspectos de la ISR. El citrato sódico es administrado por menos del 20% de los participantes. El 64% de los encuestados coloca una sonda nasogástrica en pacientes con obstrucción intestinal. El residuo gástrico se evalúa con ultrasonidos en un 6%. Una cuarta parte de los encuestados controla la eficacia de la preoxigenación con la ETO2 y el 22% utiliza la insuflación nasal de oxígeno con gafas nasales o THRIVE. El 62% de los encuestados aplica presión cricoidea, pero solo se libera en un 50% cuando aparece dificultad en la intubación. Hasta el 40% de los anestesiólogos refirieron haber tenido algún caso de aspiración a pesar de aplicar presión cricoidea. El propofol fue el hipnótico más utilizado (97,6%), mientras que no hubo una diferencia clara en la preferencia del relajante neuromuscular (ratio suxametonio versus rocuronio de aproximadamente 1:1). Solo el 44% de los encuestados calcula la dosis de sugammadex necesaria para una reversión de emergencia del rocuronio. CONCLUSIONES: La encuesta demostró una variación significativa en la práctica de la ISR, similar a la de otros países. Se necesitan estudios prospectivos de calidad para estandarizar la práctica clínica

BACKGROUND: Rapid sequence induction (RSI) in adults has undergone changes in recent years due to pharmacological and technological advances. The objective of this survey was to evaluate current practice among Spanish anesthesiologists. METHODS: A 31-item questionnaire regarding RSI practice was sent to anesthesiologists working in Spanish public hospitals. Differences in responses according to the type of hospital or experience of the respondent were compared for all data using the chi-square and Fisher's exact test. RESULTS: Approximately 15.89% of Spanish anesthesiologists participated in the survey (1002 questionnaires). The results show considerable heterogeneity in most aspects of RSI. Less than 20% of respondents administer sodium citrate. Sixty-four percent place a nasogastric tube in patients with intestinal obstruction. Gastric residue is assessed by ultrasound in 6% of cases. Only 25% of respondents measure ETO2 to check the effectiveness of preoxygenation, and 22% use nasal oxygen insufflation with nasal prongs or THRIVE. Sixty two percent of respondents apply cricoid pressure, but only 50% release the pressure when encountering intubation difficulty. Up to 40% of respondents reported cases of aspiration despite applying cricoid pressure. Propofol was the most commonly used hypnotic (97.6%), but there was no clear preference in the choice of neuromuscular relaxant (suxamethonium versus rocuronium ratio of approximately 1:1). Only 44% of respondents calculated the dose of sugammadex that would be required for emergency reversal of rocuronium. CONCLUSIONS: The survey showed significant variation in RSI practice, similar to that of other countries. Quality prospective studies are needed to standardize clinical practice

Effect of goal-directed haemodynamic therapy on postoperative complications in low-moderate risk surgical patients: a multicentre randomised controlled trial (FEDORA trial).

BACKGROUND: The aim of this study was to evaluate postoperative complications in patients having major elective surgery using oesophageal Doppler monitor-guided goal-directed haemodynamic therapy (GDHT), in which administration of fluids, inotropes, and vasopressors was guided by stroke volume, mean arterial pressure, and cardiac index. METHODS: The FEDORA trial was a prospective, multicentre, randomised, parallel-group, controlled patient- and observer-blind trial conducted in adults scheduled for major elective surgery. Randomization and allocation were carried out by a central computer system. In the control group, intraoperative fluids were given based on traditional principles. In the GDHT group, the intraoperative goals were to maintain a maximal stroke volume, with mean arterial pressure >70 mm Hg, and cardiac index ≥2.5 litres min-1 m-2. The primary outcome was percentage of patients with moderate or severe postoperative complications during the first 180 days after surgery. RESULTS: In total, 450 patients were randomized to the GDHT group (n=224) or control group (n=226). Data from 420 subjects were analysed. There were significantly fewer with complications in the GDHT group (8.6% vs 16.6%, P=0.018). There were also fewer complications (acute kidney disease, pulmonary oedema, respiratory distress syndrome, wound infections, etc.), and length of hospital stay was shorter in the GDHT group. There was no significant difference in mortality between groups. CONCLUSIONS: Oesophageal Doppler monitor-guided GDHT reduced postoperative complications and hospital length of stay in low-moderate risk patients undergoing intermediate risk surgery, with no difference in mortality at 180 days. CLINICAL TRIAL REGISTRATION: ISRCTN93543537.

A systematic review of sugammadex vs neostigmine for reversal of neuromuscular blockade.

We reviewed systematically sugammadex vs neostigmine for reversing neuromuscular blockade. We included 17 randomised controlled trials with 1553 participants. Sugammadex reduced all signs of residual postoperative paralysis, relative risk (95% CI) 0.46 (0.29-0.71), p = 0.0004 and minor respiratory events, relative risk (95% CI) 0.51 (0.32-0.80), p = 0.0034. There was no difference in critical respiratory events, relative risk (95% CI) 0.13 (0.02-1.06), p = 0.06. Sugammadex reduced drug-related side-effects, relative risk (95% CI) 0.72 (0.54-0.95), p = 0.02. There was no difference in the rate of postoperative nausea or the rate of postoperative vomiting, relative risk (95% CI) 0.94 (0.79-1.13), p = 0.53, and 0.87 (0.65-1.17), p = 0.36 respectively.

Colloids versus crystalloids in the prevention of hypotension induced by spinal anesthesia in elective cesarean section. A systematic review and meta-analysis.

The incidence of hypotension associated to spinal anesthesia in elective cesarean section is high. To determine the effects of colloids and crystalloids in the incidence of hypotension induced by spinal anesthesia in elective cesarean section, an attempt was made to define which type of fluid and what total volume should be administered. Following the PRISMA methodology a systematic review and meta-analysis were carried out. A systematic Medline/PubMed, EMBASE and Cochrane Library search was made to identify trials where women were scheduled for elective cesarean section with spinal anesthesia and volume loading (preload or co-load). The primary outcome was the incidence of hypotension. Stratification into subgroups was made for the primary outcome according to the type of colloid administered, differentiating those studies employing new generation colloids (HES 6% 130/0.4) from those not using such colloids, based on the volume of colloid administered and the combination of a vasopressor. The secondary outcome was the incidence of intraoperative nausea and vomiting. Two-hundred and twenty-seven controlled clinical trials were analyzed; eleven randomized clinical trials including 990 patients were included. A significative decrease of incidence of hypotension associated to spinal anesthesia was observed with the use of colloids compared to crystalloids (RR [95% CI] 0.70 [0.53-0.92], P=0.01). However, there was no difference between crystalloid and colloid in the risk of intraoperative nausea and vomiting (RR [95% CI] 0.75 [0.41-1.38]; P=0.33). This meta-analysis shows colloid administration to significantly reduce the incidence of hypotension associated to spinal anesthesia in elective cesarean section compared with of crystalloid use.

Shock anafiláctico prolongado de 4 días de duración / Anaphylactic shock lasting 4 days

Se presenta el caso de un varón de 62 años programado para una cistectomía radical que a los 10 min de comenzar la cirugía presentó hipotensión arterial severa, taquicardia sinusal y un aumento de las presiones en la vía aérea. No se obtuvo respuesta a la administración de diversos fármacos vasoactivos (efedrina, fenilefrina, dopamina, noradrenalina). Tras descartar otras posibles etiologías se valoró la posibilidad de que se tratara de una reacción de anafilaxia y se inició la administración de adrenalina, con lo que se consiguió estabilizar hemodinámicamente al paciente. En la unidad de reanimación fue preciso mantener la perfusión de adrenalina y la ventilación mecánica durante 4 días (AU)

We present a case of a 62 year-old male scheduled for radical cystectomy, who, ten minutes into the surgery, presented with severe hypotension, tachycardia and increased airway pressure. There was no response to the administration of vasoactive drugs such as, ephedrine, phenylephrine, dopamine and norepinephrine. After ruling out several causes, we evaluated the possibility of an anaphylactic reaction. Adrenaline was given, and the patient stabilized. An adrenaline infusion and mechanical ventilation was required for four days in the critical care unit (AU)

[Parotiditis viral infection associated with Kikuchi-Fujimoto disease. Review of 1 case]. / Enfermedad de Kikuchi-Fujimoto asociada a infección por virus de la parotiditis. A propósito de 1 caso.

Kikuchi-Fujimoto disease or necrotizing histiocytic lymphadenitis is a self-limited process of lymphatic system that affects more frequently young women. Fever and adenopathy, often cervical, are typical. Diagnosis is fundamentally based on the affected lymph node biopsy, since laboratory data are often normal. It's a very rare entity in Spain, being more frequent in Oriental countries. It's a benign evolution process, with a spontaneous healing in some weeks or months. This is the reason because of this disease could be infradiagnosed. It's very important the differential diagnosis with malignant lymphomas, because Kikuchi-Fujimoto disease doesn't need any treatment.

Enfermedad de Kikuchi-Fujimoto asociada a infección por virus de la parotiditis. A propósito de 1 caso / Parotiditis viral infection associated with Kikuchi- Fujimoto disease. Review of 1 case

La enfermedad de Kikuchi-Fujimoto o linfadenitis necrotizante histiocitaria es un proceso autolimitado del sistema linfático que afecta con más frecuencia a mujeres jóvenes. Clínicamente se caracteriza por la presencia de fiebre y de adenopatías, sobretodo cervicales. El diagnóstico se basa fundamentalmente en la biopsia del ganglio afectado, ya que a menudo los datos de laboratorio son normales. Es una enfermedad rara en España, siendo más frecuente en países orientales. Se trata de un proceso de evolución benigna, con resolución espontánea en semanas o meses, razón por la cual esta enfermedad podría estar infradiagnosticada. Es fundamental su distinción de los linfomas, dado que la enfermedad de Kikuchi no necesita tratamiento (AU)
