Resumo

JUSTIFICATIVA E OBJETIVOS: A abordagem das vias aéreas como uso do laringoscópio pode causar diversos tipos de traumatismos. Este estudo teve como objetivo tentar esclarecer se o método de intubação que utiliza o estilete luminoso pode ser uma alternativa menos traumática para o paciente em comparação ao método por laringoscopia direta. MÉTODO: O presente estudo envolveu 98 pacientes de 16 a 88 anos, estado físico ASA I e II. Os pacientes foram divididos em dois grupos: Grupo L, submetido à intubação com laringoscópio, com 54 pacientes, e Grupo E, intubado com estilete luminoso, com 44 pacientes. Foram avaliados o número de tentativas para intubação, tempo de intubação, variação de pressão arterial e frequência cardíaca, dor de garganta (odinofagia), disfagia e rouquidão pós-operatória. RESULTADOS: Os dados demográficos e os parâmetros hemodinâmicos foram semelhantes entre os grupos. Não houve diferença estatística significativa na pesquisa de dor de garganta e disfagia entre os dois grupos. A rouquidão foi o único dado estudado em que se observou diferença estatística significativa, mais predominante no grupo E (p = 0,05). CONCLUSÕES: Ambas as técnicas de intubação são semelhantes em relação ao comportamento hemodinâmico dos dois grupos. No entanto, o grupo com estilete luminoso apresentou maior frequência do sintoma rouquidão.

Abstract

BACKGROUND AND OBJECTIVES: Approaching the airways with a laryngoscope can cause different types of injuries. The objective of the present study was to determine whether lighted stylet tracheal intubation can be a less traumatic alternative for patients when compared to direct laryngoscopy. METHODS: Ninety-eight patients between 16 and 88 years and physical status ASA I and II participated in the present study. Patients were separated into two groups: Group L, 54 patients who were intubated with a laryngoscope, and Group E, 44 patients who were intubated with a lighted stylet. The number of attempts, time until intubation, variation in blood pressure and heart rate, and postoperative sore throat (odynophagia), dysphagia, and hoarseness were evaluated. RESULTS: Demographic data and hemodynamic parameters were similar in both groups. Statistically significant differences in the incidence of sore throat and dysphagia were not observed. Hoarseness was the only data that showed statistically significant differences, being more predominant in Group E (p = 0.05). CONCLUSIONS: The intubation techniques are similar regarding the hemodynamic behavior in both groups. However, hoarseness was more common in group with lighted stylet.
