A comparison of tracheal intubation guided by Lightwand,Shikani optical stylet or Macintosh / 实用医学杂志

ABSTRACT

Objective To compare of the application of tracheal intubation guided by Lightwand,Shikani optical stylet,or Macintosh. Methods Ninety ASA Ⅰ~Ⅱ patients undergoing elective general anesthesia were randomly divided into three groups(n = 30)Macintosh group(group M),Lightwand group(group L)and Shi-kani optical stylet group(group S). MAP and HR were recorded at the time of entering the operating room(T1), before intubation(T2),at the immediate time of intubation(T3),3 mins(T4)and 5 mins after intubation(T5). The intubation duration,the first intubation success rate,the number of intubation,and the incidence of complications including sore throat were observed. Results As compared with T1,MAP and HR decreased significantly at T2in the three groups(P<0.05). As compared with T2,HR increased in group L and MAP and HR increased in group S at T3(P<0.05). As compared with group M,MAP and HR at T4and T5were lower in groups L and S(P<0.05). The first intubation time was obviously shorter in group L than in other groups(P<0.05). The incidence of compli-cations was lower in group S(P < 0.05). The first success rate of intubation,the intubation times and the inci-dence of airway complications did not differ significantly among the three groups.(P > 0.05). Conclusions As compared with Macintosh,Lightwand and Shikani optical stylet have less influence on hemodynamic parameters. Lightwand needs shorter intubation time,Shikani optical stylet has the lowest rate of sore throat.
