Objective:To study the safety and efficacy of blind orotracheal intubation via BlockBuster laryngeal mask(BBMLA).Methods:One hundred patients, ASA I or II, between 18 and 80 years old were enrolled in this study.General anaesthesia was induced with Fentanyl 4μg/kg i.v, Propofol 1.5-2mg/kg i.v and Rocuronium 0.6mg/kg i.v.An effective mask ventilation was performed.The BBLMA was gradually introduced into position,the cuff was inflated with air and the ability to ventilate was confirmed. A fiberoptic scope was then inserted through the airway to grade the scoring of the glottis view .Making sure the fiberoptic scoring was less than 2.Then,patients were intubated blindly through the BlockBuster laryngeal mask airway.The number of adjusting manoeuvres, time to intubation, intubation success rates, haemodynamic changes (pre-induction, pre-intubation, postintubation), oesophageal intubation, mucosal trauma (blood detected), hypoxia (oxygen saturation < 95%) and postoperative pharyngolaryngeal morbidity (double-blinded) were documented. Results: All one hundred patients were intubated in one or two attempts .Time to successful BBLMA insertion was11.0±3.2 s, Time to successful intubation was10.5±6.2 s.There were no significant differences in blood pressure or heart rate among the groups at any time.Conclusion: Blind intubation through the BlockBuster laryngeal mask have many advantage,safe and quickly,effective and comfortable. It’s a better choice in the difficult airway management.
