Abstract:
Objective To evaluate the value of TruviewTM EVO2 optical laryngoscope for emergency endotracheal intubation in the clinical application.Methods Forty-four patients in need for emergency endotracheal intubation were randomly (random number) divided into two groups:the observation group (TruviewTM EVO2 optical laryngoscope for tracheal intubation,n =22) and the control group (ordinary laryngoscope for tracheal intubation,n =22).Parameters recordered included C/L (Cormack-Lehane)grade,the time taken for successful intubation,tracheal intubation times,lowerest SpO2 during the intubation and the incidences of complications after intubation.IDS (intubation difficulty scale) scores were calculated and the total effective rates were compared.Results The data showed that there were no significant differences in the duration of the successful endotracheal intubation attempts between the two groups,respectively (24.04 ±6.56) s and (21.97 ±8.92) s,P ＞0.05.The C/L grade with the observation group was 10∶ 9∶ 3∶0 (Ⅰ ∶ Ⅱ ∶ Ⅲ∶ Ⅳ),which was significantly better than that with the control group (3∶ 7∶ 9∶ 3,P ＜0.01).The tracheal intubation times of the observation group was 17∶ 5∶0 (one time∶ two times∶ three times),which was significantly better than that of the control group (9∶ 8∶ 5,P ＜0.01).The minimum of SpO2 in the observation group (97.31 ± 1.64)％ was significantly higher than that in the control group (92.03 ± 5.39)％,(P ＜ 0.01).The incidence of complications after intubation was lower in the observation group.The IDS score in the observation group (0.68 ± 0.38) was much lower than those in the control group (2.54 ± 1.49),(P ＜ 0.01).In addition,the total effective rate of the observation group (86.36％) was significantly higer than that in the control group (45.45％),(P ＜0.01).Conclusions Using optical laryngoscope for emergency endotracheal intubation could facilitate the glottis exposure and reduce C/L grade effectively.It could lead to lower the incidence of complications and increase the success rate of tracheal intubation.
