  • Title: LMA Supreme insertion by novices in manikins and patients.
    Author: Howes BW, Wharton NM, Gibbison B, Cook TM.
    Journal: Anaesthesia; 2010 Apr; 65(4):343-7. PubMed ID: 20180796.
    Abstract:
    The LMA Supreme has been suggested for use in emergency situations by medical personnel with no experience in endotracheal intubation. We evaluated the LMA Supreme when inserted by non-anaesthetists, firstly in a manikin and then in patients. Fifty airway novices inserted a LMA Supreme in a manikin without any complications so we proceeded to the patient phase. Fifty airway novices inserted the LMA Supreme in anaesthetised patients undergoing elective surgery. First time insertion success rate was 86% and overall insertion success rate was 100%. Mechanical ventilation was successful in all cases. Median (IQR [range]) time to establish an airway was 34 s (26-40 [18-145] s). Median (IQR [range]) pharyngeal seal pressure was 23 cmH(2)O (19-28 [13-40] cmH(2)O). There were no important complications. Results are consistent with previous studies of use of the LMA Supreme by airway experts. We conclude that the LMA supreme is suitable for use by airway novices. Further research is needed before it may be recommended for cardiopulmonary resuscitation and emergency airway use.
