First Attempt Insertion Success of Novel Two Person Lateral Rotation Technique V.S Standard Brain Technique for LMA Insertion (LMA insertion)
First-Attempt Insertion Success of a Novel Two-Person Lateral Rotation Technique Versus the Standard Brain Technique for Laryngeal Mask Airway Placement: A Randomized Controlled Trial
The goal of this clinical trial is to learn if two person lateral rotation technique of LMA insertion is more successful than the standard technique in achieving effective ventilation on the first introduction of the LMA .The main questions it aims to answer are:
Does two person lateral rotation technique of LMA insertion lower the number of times needed to inesrt the LMA ?
Researchers will compare two person lateral rotation technique of LMA insertion to standard technique to see if it is more successful
Participants will be subjected to the two way of LMA insertion

Hvad måler undersøgelsen?
Primære resultatmål

|
1 minute after LMA insertion

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Insertion time
Tidsramme: 20-90 seconds from picking up the LMA to be inserted in the mouth
|
Interval from picking up the LMA to confirmation of effective ventilation (square-wave capnogram, no audible leak at 20 cmH₂O, normal chest movement)
|
20-90 seconds from picking up the LMA to be inserted in the mouth
|
|
Number of attempts
Tidsramme: 2-3 minutes after induction of anesthesia
|
Recorded up to a maximum of three; failure defined as inability to achieve effective ventilation after three attempts
|
2-3 minutes after induction of anesthesia
|
|
Need for manipulations
Tidsramme: 1-2 minutes after induction of anesthesia
|
Chin lift, jaw thrust, head extension, neck flexion, or moderate advancement recorded as binary
|
1-2 minutes after induction of anesthesia
|
|
Oropharyngeal leak pressure (OLP)
Tidsramme: 1-2 minutes after insertion of LMA
|
Measured by closing the expiratory valve at a constant gas flow of 3 L/min with the upper pressure limit set to 30 cmH₂O; the pressure at which an audible leak is detected is recorded
|
1-2 minutes after insertion of LMA
|
|
Complications:
Tidsramme: immediate after removal of LMA ,1,2,4,24 hours. post operative
|
Blood staining on LMA (indicating mucosal trauma), sore throat (assessed postoperatively using a 4-point verbal rating scale), laryngospasm, hypoxia (SpO₂ < 92%), and gastric insufflation (detected by epigastric auscultation)
|
immediate after removal of LMA ,1,2,4,24 hours. post operative
