A comparison of the intubating laryngeal mask airway and the Bonfils intubation fibrescope in patients with predicted difficult airways 总被引:4,自引:0,他引:4
Bein B Worthmann F Scholz J Brinkmann F Tonner PH Steinfath M Dörges V 《Anaesthesia》2004,59(7):668-674
Tracheal intubation with the intubating laryngeal mask airway or the Bonfils intubation fibrescope was performed in 80 patients with predicted difficult airways. Mallampati score, thyromental distance, mouth opening and mobility of the atlanto-occipital joint were used to predict difficult airways. The overall success rate, time to the first adequate lung ventilation and time taken for the successful placement of the tracheal tube were recorded, as well as a subjective assessment of the handling of the device and the incidence of postoperative sore throat and hoarseness. The median [range] time to the first adequate ventilation was significantly shorter with the intubating laryngeal mask airway than with the Bonfils intubation fibrescope (28 [6-85] s vs. 40 [23-77] s, p < 0.005). Tracheal intubation was significantly slower with the intubating laryngeal mask airway than with the Bonfils intubation fibrescope (76 [45-155] s vs. 40 [23-77] s, p < 0.0001. Patients in the Bonfils group suffered less sore throat and hoarseness than those in the other group. 相似文献

Study ObjectiveTo assess the efficacy of both Bonfils and GlideScope in obese patient with difficult airways for bariatric surgery using awake intubation.DesignComparative study.SettingOperating room.PatientsThe study was carried out on 60 patients, for laparoscopic bariatric surgery, after approval of the Medical Ethics Committee and having an informed written consent from each patient. Patients were randomly categorized into 2 equal groups 30 patients in each group.InterventionsAwake intubation with either Retromolar Bonfils or GlideScope.MeasurementsTime to visualize the laryngeal inlet, time of intubation, time of scope manipulation, success rate at each attempt, the lowest oxygen saturation, hemodynamic parameters, and any complication.Main ResultsRegarding intubation criteria, GlideScope achieves shorter times compared with Retromolar for visualization of the vocal cords and intubation, in addition to less intubation attempts, but both without a statistically significant difference. Retromolar shows better patient satisfaction than does GlideScope, with statistically significant difference.ConclusionsBoth Bonfils fiberscope and the GlideScope can be successfully used for awake intubation in morbidly obese patients with expected difficult airways. Bonfils intubating fiberscope was more tolerated by patients with statistical difference; on the other hand, GlideScope provided shorter intubation time and less intubation attempts but not statistically significant. 相似文献

Tracheal intubation using the Bonfils intubation fibrescope after failed direct laryngoscopy 总被引:5,自引:0,他引:5
Failed tracheal intubation due to a difficult airway is an important cause of anaesthetic morbidity and mortality. This study was undertaken to evaluate the effectiveness of the Bonfils intubation fibrescope for tracheal intubation after failed direct laryngoscopy. Twenty-five patients undergoing coronary artery bypass grafting were enrolled in the study after two attempts at conventional laryngoscopy by a board certified anaesthetist had failed. Intubation with the Bonfils fibrescope was successful on the first attempt in 22 patients (88%) and on the first or second attempt in 24 patients (96%); in one patient intubation was impossible. Median (IQR [range]) time to intubation using the Bonfils intubation fibrescope was 47.5 (30-80 [20-200]) s. Tracheal intubation using the Bonfils intubation fibrescope appears to be a simple and effective technique for the management of a difficult intubation. 相似文献

ObjectiveUnanticipated difficult tracheal intubation is a significant source of morbidity and mortality in anesthetized patients. A number of modules have been developed to predict difficult airways, but they are often complex in nature. We combined the modified Mallampati score (M), thyromental distance (T), anatomical abnormality (A), and cervical mobility (C) into a single scoring system with the acronym M-TAC, and evaluated it against Mallampati scoring.MethodsWe prospectively analyzed 500 adult patients of the American Society of Anesthesiologists (ASA) class I or II, scheduled for elective surgery under general anesthesia. Preoperative airway assessments using M-TAC were performed, all of which were given a score. Anesthesiologists, blinded to the pre-anesthetic airway assessment, performed laryngoscopy and graded the laryngoscopic view as per Cormack and Lehane's classification. For the study purpose, difficult laryngoscopy was defined as Cormack and Lehane Grade 3 or 4 of laryngoscopic view.ResultsAn M-TAC score ≥ 4 had a significantly higher sensitivity (96% vs. 72%) and specificity (86% vs. 78%) with a high positive predictive value (44% vs. 28%) and a very low false negative value (2% vs. 15%) in comparison with Mallampati scoring (p < 0.05). Analysis of the receiver operating characteristic (ROC) curve for predicting difficult laryngoscopy revealed an area under the curve of 0.83 (95% CI = 0.78–0.88) for Mallampati scoring and 0.94 (95% CI = 0.92–0.96) for M-TAC scoring system.ConclusionThe M-TAC scoring system has provided a higher sensitivity and specificity in predicting difficult laryngoscopy in comparison with Mallampati classification. 相似文献
