摘要: Laryngoscopy can induce stress responses that may be harmful in susceptible patients. We directly measured the force applied to base of tongue as a surrogate for response. Force measurements were obtained using three FlexiForce Sensors(®) (Tekscan Inc, Boston, MA, USA) attached along concave surface each laryngoscope blade. Twenty-four 24 adult patients ASA physical status 1-2 studied. After induction anaesthesia and neuromuscular blockade, laryngoscopy tracheal intubation was performed either Macintosh or GlideScope(®) (Verathon, Bothell, WA, laryngoscope. Complete data available 23 Compared with Macintosh, we observed lower median (IQR [range]) peak (9 (5-13 [3-25]) N vs 20 (14-28 [4-41]) N; p = 0.0001), average (5 (3-7 [2-19]) 11 (6-16 [1-24]) 0.0003) impulse (98 (42-151 [26-444]) Ns 150 (93-207 [17-509]) Ns; 0.017) GlideScope. Our study shows lifting on during is less GlideScope videolaryngoscope compared
