Brief Summary:
Comparison of Intubation using Pentax (Pentas AWS, Pentax, Tokyo, Japan) and Macintoch in pediatric patients

Condition or disease Intervention/treatment
Intubation;Difficult Device: Pentax

Detailed Description:

Pentax video laryngoscope (Pentas AWS, Pentax, Tokyo, Japan) is one of indirect optical laryngoscopes which is recently developed. Several studies have shown that the Pentax-AWS® provides full views of the glottis in the majority of patients. It makes successful tracheal intubation in patients after failed intubation using a Macintosh laryngoscope.

In pediatric patients who is expected to be difficult to intubate, Pentax makes successful intubation.

Intubation using Pentax
Device: Pentax
Intubation using Pentax video laryngoscope in Pentax group

Macintosh group
Intubation using Macintosh

Primary Outcome Measures :
  1. Intubation time [ Time Frame: less than 10 minute ]
    from laryngoscope pass incisors to end tidal CO2 appears

Secondary Outcome Measures :
  1. Intubation difficulty score [ Time Frame: less than 10 minute ]
    IDS parameter is Number of attempts > 1 = N1 Number of operators >1 = N2 Number of alternative techniques = N3 Cormack and Lehane grade minus 1 = N4 Operator perception of lifting force required Normal N5 = 0 Greater than in routine practice N5=1 Laryngeal pressure applied Not applied N6=0 Applied N6=1 Vocal core mobility Abduction N7=0 Adduction &/or impending tube passage N7=1 Total IDS = sum of scores N1~N7
