Abstract
Objective
This study aimed to investigate the potential reduction of cardiovascular stress response caused by suspension laryngoscopic surgery through the application of lidocaine spray on the larynx and trachea.
Methods
A total of 68 patients scheduled for elective suspension laryngoscopic surgery were randomly assigned to either the lidocaine group (Group L, n = 34) or the control group (Group C, n = 33). In Group L, patients received a sprayed lidocaine dose of 2 mg/kg on the larynx and trachea after anesthesia induction, prior to intubation. In Group C, equal volumes of saline solution were administered. MAP and HR were recorded at various time points: before anesthesia (T0), 1-minute after intubation (T1), 1 and 3 min after suspension laryngoscopy (T2 and T3), at the end of the operation (T4), and at 1, 5, and 30 min after extubation (T5, T6, and T7). Arterial blood glucose, epinephrine, and norepinephrine levels were measured at T0, T2, T5, and T7. The occurrence of severe cough and sore throat at T6 and T7 after extubation was compared between the two groups.
Results
At T0 and T1, there were no statistically significant differences in mean arterial pressures, heart rate, and blood catecholamine levels between the two groups. However, from T2 to T7, the blood pressure and heart rate in Group L were lower compared to Group C, with significant differences observed at T2‒T6 (p < 0.05). Group L also showed less elevation in blood glucose at T2, T5, and T7 (p < 0.05). The changes in epinephrine and norepinephrine levels between the two groups were statistically significant at T2 and T5 (p < 0.05).
Conclusions
Administering lidocaine spray on the larynx and trachea during intubation for suspension laryngoscopic surgery can effectively alleviate the stress response.
Level 1 evidence
Patients in this study are randomly assigned to the treatment or control group and are followed prospectively.
期刊介绍:
Brazilian Journal of Otorhinolaryngology publishes original contributions in otolaryngology and the associated areas (cranio-maxillo-facial surgery and phoniatrics). The aim of this journal is the national and international divulgation of the scientific production interesting to the otolaryngology, as well as the discussion, in editorials, of subjects of scientific, academic and professional relevance.
The Brazilian Journal of Otorhinolaryngology is born from the Revista Brasileira de Otorrinolaringologia, of which it is the English version, created and indexed by MEDLINE in 2005. It is the official scientific publication of the Brazilian Association of Otolaryngology and Cervicofacial Surgery. Its abbreviated title is Braz J Otorhinolaryngol., which should be used in bibliographies, footnotes and bibliographical references and strips.
