RESUMO

Introducción: La cirugía de tiroides y paratiroides asocia frecuente morbilidad, destacando las lesiones de los nervios laríngeo superior y recurrente. La utilización de la mascarilla laríngea Pro-Seal® (ML-PS), permite la visualización endoscópica de las cuerdas vocales al estimular dichos nervios, facilitando su identificación y reduciendo las secuelas. Además, la ausencia de intubación permite una rápida recuperación, así como la valoración funcional laríngea al término de la cirugía, diagnosticando y resolviendo precozmente cualquier complicación, facilitando la CMA. Objetivo: Valorar clínicamente la ML-PS como dispositivo de ventilación en cirugía de tiroides y paratiroides y sus posibles aportaciones. Material y métodos: Se incluyeron 37 pacientes, ASA I-II, programados para cirugía de tiroides o paratiroides. Registramos la facilidad de inserción, sellado, presión de fuga, eficacia ventilatoria, estabilidad hemodinámica, exposición del campo, funcionalidad de los nervios recurrentes y complicaciones asociadas. Resultados: La ML-PS se colocó al primer intento en el97,3% de los casos, las presiones medias de fuga y pico fueron40 y 26 cm H2O respectivamente, manteniendo adecuada ventilación. No se registraron alteraciones hemodinámicas tras su colocación ni complicaciones significativas. Solamente en uno de los casos se precisó neuroestimulación, y en otro caso se pudo diagnosticar precozmente una afectación recurrencial postoperatoria. Conclusiones: La facilidad de colocación, buen sellado, eficacia ventilatoria y ausencia de complicaciones significativas hacen de la ML-PS un dispositivo seguro y eficaz, permitiendo la rápida recuperación del procedimiento anestésico, facilitando el alta del paciente. Además, la mejor exposición e identificación nerviosa yla posibilidad de revisión al concluir la cirugía configuran la ML-PS como un elemento útil que contribuye a reducir la morbilidad operatoria (AU)


Background: Thyroid and parathyroid surgery are associated with upper and recurrent laryngeal nerve injury. The ProSeal®Larynx mask (LM-PS) allows endoscopic visualisation of the vocal cords during the stimulation of these nerves. This facilitates the identification of these nerves, reducing complications. Furthermore, avoiding endo-tracheal intubation allows a faster recovery and a functional larynx evaluation at the end of surgery, facilitating ambulatory surgery. Objective: To clinically evaluate the LM-PS as a ventilation device in thyroid and parathyroid surgery. Material and methods: Thirty seven patients (ASA I or II),operated on electively because of thyroid or parathyroid diseases, were included in the study. We collected data on: facility of insertion, seal, leakage pressure, effectiveness of ventilation, hemodynamicstatus, correct exposition, laryngeal nerve function and associated complications. Results: LM-PS was inserted on the first attempt in 97.3% of the patients. Mean leak and peak pressures were 40 and 26 cmH2O respectively, maintaining adequate ventilation. No hemodynamicalterations were registered. Only one case needed neurostimulation. I n another case we diagnosed a postoperative recurrent laryngeal nerve injury. Conclusions: The main qualities of the LM-PS mask are its facility of use, its efficiency for ventilation and the absence of significant complications. All these allow quick post-anaesthetic recovery facilitating patient’s discharge. The laryngeal nerve identification at surgery contributes to reducing surgical morbidity (AU)

RESUMO

Neuromuscular monitoring is not a routine practice in clinical settings worldwide. The little interest expressed is mainly because clinicians lack information and documentation, even though the literature on the subject is vast and experts agree that routine monitoring reduces morbidity related to the use of neuromuscular blockers. We report a case of an unusual phase II neuromuscular block from a subclinical dose of succinylcholine. The blockade lasted longer than expected in a patient with diminished plasma cholinesterase activity. We emphasize that monitoring neuromuscular function aided diagnosis and observation of the block during emergency surgery.

RESUMO

La monitorización neuromuscular es una práctica clínicapoco habitual en todo el mundo. Existe poco interésfundamentado en la falta de información y documentación.Aún así la enorme literatura publicada y los expertosestán de acuerdo en que la monitorización rutinariadisminuye la morbilidad relacionada con el uso de losbloqueantes neuromusculares. Describimos un caso debloqueo neuromuscular por succinilcolina a dosis subclínicas,más prolongado de lo esperable en un pacientecon actividad colinesterásica plasmática reducida, quedesarrolló un bloqueo en fase II, fenómeno poco habitual.Queremos hacer énfasis en la ayuda que aportó lamonitorización de la función neuromuscular como diagnósticoy observación del bloqueo neuromuscular en elcontexto de la cirugía de urgencias(AU)

RESUMO

UNLABELLED: The laryngeal tube, an effective new device for rapid airway management, allows the caregiver to intubate without a direct laryngoscopic view of the oropharynx and larynx. OBJECTIVES: To evaluate the clinical performance of the laryngeal tube in terms of efficacy of the seal against gastric content reflux and for ventilating patients requiring elevated ventilatory pressures because of high respiratory resistance. PATIENTS AND METHODS: Sixty patients (32 women, 28 men; mean age 48 +/- 20 y) requiring surgery under general anesthesia were enrolled. We monitored oxygenation and ventilation and evaluated ease of laryngeal tube placement, the occurrence of regurgitation and whether or not gastric contents reached the airway. RESULTS: The laryngeal tube was easy to insert and insertion was possible on the first try for 48 of the 60 patients (80%). Repositioning to permit optimal ventilation was necessary for 8 patients (13.3%), the tube had to be removed and re-inserted for 2 patients (3.3%), and ventilation through the laryngeal tube was impossible for 2 (3.3%). Oxygenation and ventilation were adequate in all cases in which the laryngeal tube could be inserted. Regurgitation was observed in 3 patients (5%), but the seal remained closed in all cases. CONCLUSIONS: A laryngeal tube is an effective way to establish airway access. It is easy to insert and in all cases allows for adequate oxygenation and ventilation and prevents gastric contents from reaching the airway.
