目的比较Truview^TM EVO2光学喉镜与Macintosh直接喉镜在经口气管插管中显露喉部结构的效果,探讨该光学喉镜在全麻气管插管中的应用价值。方法经口气管插管全身麻醉下实施择期手术的ASAI-Ⅱ级成人患者200例。麻醉前记录人选患者一般情况和气道评估指标(Mallampati舌咽结构分级、甲颏间距、张口度)。全麻诱导后随机应用直接喉镜或光学喉镜先后显露喉部结构并记录Cormack-Lehane喉部结构显露分级(C/L分级),用后一种喉镜进行气管插管。观察指标包括术前患者一般情况及气道评估指标;C/L分级;喉部结构显露难易度;口咽部损伤;术后咽痛、声音嘶哑等并发症。结果200例患者中男107例,女93例,年龄52岁±13岁,身高164.8cm±11.3cm,体重64.0kg±11.5kg,甲颏间距6.9cm±1.1cm,张口度3.7cm±0.5cm。两种喉镜C/L分级均与Mallampati舌咽结构分级具有相关性(P〈0.01),即Mallampati分级越高,C/L分级越高。有91例两种喉镜C/L分级相同,其中76例为I级,15例为Ⅱ级;4例喉镜C/L分级优于光学喉镜,余105例则光学喉镜优于直接喉镜;在200例病人中,用直接喉镜C/L分级百分比分别为:I级40.O%、Ⅱ级38.5%、Ⅲ级20.5%、IV级1%;而光学喉镜为:I级78.5%、Ⅱ级21.0%、Ⅲ级0.5%。所有患者未记录到明显口咽部损伤和术后咽痛及声音嘶哑。结论Truview^TM EVO2光学喉镜对喉部结构显露C/L分级明显优于Macintosh直接喉镜,从而提示应用光学喉镜可能有助于困难气道的处理。 相似文献

The view of the larynx using the Macintosh laryngoscope and the McCoy levering laryngoscope was assessed in 177 adult patients. The view with the McCoy blade in the neutral position and in the position (neutral or elevated) that gave the 'best' view were recorded. The McCoy blade in the neutral position was associated with a lower incidence of grade 1 views and a higher incidence of grade 2 views than the Macintosh blade. There was no difference in the incidence of grade 3 views. When views for each patient using the different blades were compared, the McCoy blade in the neutral position produced a worse view than the Macintosh blade (p < 0.0001). The view obtained with the McCoy blade in its 'best' position and the Macintosh blade were similar. In the 152 patients in whom the vocal cords were seen using the Macintosh blade, the view was worse using the McCoy blade in its 'best' position more often than it was better (p = 0.06). In 25 patients, the vocal cords could not be seen with the Macintosh blade; in these patients the view was better with the McCoy blade (the cords were visible) on 14 occasions and worse in one (p = 0.001). We conclude that the McCoy blade in its neutral position does not behave identically to the Macintosh blade. The McCoy blade is a useful aid to difficult intubation but should not replace the Macintosh blade as the first choice laryngoscope. 相似文献

Study ObjectiveTo evaluate the performance of the Pentax-AWS airway scope for tracheal intubation compared with the Macintosh laryngoscope by non-anesthesia residents.DesignProspective, randomized, cohort study.SettingUniversity-affiliated hospital.Patients520 patients who underwent tracheal intubation for general anesthesia.Interventions48 non-anesthesia residents performed tracheal intubation using either the Pentax-AWS or the Macintosh laryngoscope.MeasurementsTime to complete tracheal intubation, number of attempts until successful intubation, and number of intubations of the esophagus were recorded.ResultsTime to secure the airway (sec; mean ± SD) was shorter with the Pentax-AWS than with the Macintosh laryngoscope (44 ± 19 vs. 71 ± 44 sec; P < 0.001). Of the 264 tracheal intubations with the Pentax-AWS, 239 (91%) were completed within 60 seconds, while only 148 (58%) of the 256 tracheal intubations performed with the Macintosh laryngoscope were completed within the same period. The rate of successful intubations on the first attempt was higher with the Pentax-AWS than the Macintosh laryngoscope (P < 0.001). No esophageal intubation was experienced with the Pentax-AWS approach, while 18 occurred with the Macintosh laryngoscope (P < 0.001).ConclusionThe Pentax-AWS appears to require less operator skill than the Macintosh laryngoscope. Use of the Pentax-AWS may reduce the time to secure the airway and the incidence of failed tracheal intubation by non-anesthesia residents. 相似文献

Background: The Pentax Airwayscope®, the Glidescope®, and the TruviewEVO2® constitute three novel laryngoscopes that facilitatevisualization of the vocal cords without alignment of the oral,pharyngeal, and tracheal axes. We compared these devices withthe Macintosh laryngoscope in a simulated easy and difficultlaryngoscopy. Methods: Thirty-five experienced anaesthetists were allowed up to threeattempts to intubate in each of four laryngoscopy scenariosin a Laerdal® SimMan® manikin. The time required toperform tracheal intubation, the success rate, number of intubationattempts and of optimization manoeuvres, and the severity ofdental compression were recorded. Results: In the simulated easy laryngoscopy scenarios, there was no differencebetween the study devices and the Macintosh in success of trachealintubation. In more difficult tracheal intubation scenarios,the Glidescope® and Pentax AWS®, and to a lesser extentthe Truview EVO2® laryngoscope demonstrated advantages overthe Macintosh laryngoscope including a better view of the glottis,greater success of tracheal intubation, and ease of device use.The Pentax AWS® was more successful in achieving trachealintubation, required less time to successfully perform trachealintubation, caused less dental trauma, and was considered bythe anaesthetists to be easier to use. Conclusions: The Pentax AWS® laryngoscope demonstrated more advantagesover the Macintosh laryngoscope than either the Truview EVO2®or the Glidescope® laryngoscope, when used by experiencedanaesthetists in difficult tracheal intubation scenarios. 相似文献

Aim: To compare time to intubation, time to optimal laryngoscopy, best laryngeal view, and success rate of intubation with pediatric Bullard laryngoscope and short‐handled Macintosh laryngoscope in children being intubated with neck stabilization. Background: Securing airway of a patient with restricted cervical spine movement has been a challenge faced by anaesthesiologists around the world. Macintosh laryngoscope with manual inline stabilization is most commonly used. Bullard laryngoscope is also useful in this situation as minimal neck movement occurs with its use. Methods: Forty patients, ASA I or II, aged 2–10 years, were enrolled in this prospective, controlled, and randomized study. Patients were randomly allocated to one of two groups: Group MB (first laryngoscopy using short‐handled Macintosh laryngoscope followed by pediatric Bullard laryngoscope) and Group BM (first laryngoscopy using pediatric Bullard laryngoscope followed by short‐handled Macintosh laryngoscope) with manual inline stabilization after induction of anesthesia and paralysis. Trachea was intubated orally using the second equipment. Results: Laryngeal view when obtained was always Grade 1 with Bullard laryngoscope (38/38) when compared to Macintosh laryngoscope [Grade 1 (10/40)]. The mean time to laryngoscopy (and intubation) was shorter with Macintosh laryngoscope [15.53 s (38.15 s)] than Bullard laryngoscope [35.21 s (75.71 s)], respectively. Success rate of intubation was higher with Macintosh laryngoscope (100%) when compared to Bullard laryngoscope (70%). Conclusions: Laryngoscopy and intubation is faster using a short‐handled Macintosh laryngoscope with a higher success rate compared to pediatric Bullard laryngoscope in pediatric patients when manual inline stabilization is applied. 相似文献

Airway management in patients with periglottic tumour is a high‐risk procedure with potentially serious consequences. There is no consensus on how best to secure the airway in this group of patients. We conducted a feasibility study of awake tracheal intubation using a King Vision® videolaryngoscope with a channelled blade in a cohort of 25 patients, with a periglottic tumour requiring diagnostic or radical surgery. We used 10% and 4% lidocaine to topicalise the airway and midazolam and remifentanil for sedation. We recorded the success rate, number of attempts, time to obtain glottic view, time to intubation and complications. Twenty‐three of the 25 patients (92%, 95%CI 75–98%) were intubated with the awake videolaryngoscope‐assisted technique, with 17/23 (74%, 95%CI 54–87%) intubations achieved at the first attempt. Five patients required two and one patient, three attempts at intubation. Two patients (8%, 95%CI 2–25%) could not tolerate the procedure due to inadequate topical anaesthesia. Median (IQR [range]) times to obtain glottic view and to intubate were 19 (17–22 [10–30]) s and 49 (42–71 [33–107]) s, respectively. Traces of blood in the airway were observed in 4/25 (16%, 95%CI 6–35%) patients. Although airway management in this group of patients was expected to be difficult, successful awake intubation with the King Vision videolaryngoscope was achieved in the majority of patients within less than a minute. This study highlights a number of potential advantages of awake videolaryngoscope‐assisted intubation over other awake methods of securing the airway in patients with upper airway obstruction due to periglottic mass. 相似文献
