Resumo

JUSTIFICATIVA E OBJETIVOS: Sellick descreveu a importância da pressão aplicada na cartilagem cricóide para a prevenção da regurgitação do conteúdo gástrico durante a indução da anestesia. Desde então a manobra tem sido universalmente aceita pelos anestesiologistas como um passo fundamental durante a indução com a técnica de seqüência rápida. O presente artigo teve como objetivo discutir as indicações, a técnica, as complicações e os motivos pelos quais alguns autores têm contestado a eficácia dessa técnica. CONTEÚDO: Foram revisadas as indicações, a técnica e as complicações da manobra de compressão da cartilagem cricóide. Também foram discutidos os aspectos que têm motivado alguns autores a abandonar a manobra de Sellick durante a indução anestésica com a técnica de seqüência rápida. CONCLUSÕES: A aplicação da manobra de compressão da cartilagem cricóide exige o conhecimento da anatomia da via aérea superior e da força correta a ser empregada. Estudos endoscópicos e radiológicos, assim como pacientes que apresentaram aspiração pulmonar a despeito da aplicação da manobra de Sellick, têm colocado em questão a utilidade da técnica. Além disso, quando mal empregada, pode causar deformidade dessa cartilagem, fechamento das cordas vocais e dificuldade de ventilação. Apesar do papel de destaque representado pela manobra de Sellick na prevenção da aspiração pulmonar, não há garantia de proteção das vias aéreas para todos os pacientes, sobretudo quando a técnica não é corretamente aplicada.

Abstract

BACKGROUND AND OBJECTIVES: Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents. Since then, the maneuver has been widely accepted by anesthesiologists as a fundamental step during induction with the rapid sequence technique. The objective of the present report was to discuss the indications, technique, complications, and reasons why some authors have refuted the efficacy of this technique.
CONTENTS: The indications, technique, and complications of compression of the cricoid cartilage were reviewed. The aspects that have motivated some authors to abandon the Sellick maneuver during anesthetic induction with the rapid sequence technique are also discussed.
CONCLUSIONS: The cricoid cartilage pressure maneuver requires knowledge of the anatomy of upper airways and the correct force to be used. Endoscopic and radiologic studies, as well as patients who developed pulmonary aspiration despite the use of Sellick maneuver, have raised doubts about the usefulness of this technique. Besides, can cause deformity of the cricoid cartilage, closure of the vocal cords, and difficulty to ventilate if it is not used properly. Despite the importance given to Sellick maneuver in preventing pulmonary aspiration, there are no guarantees it will protect the airways of all patients, especially when the technique is not properly used.
