Descripción detallada
All patients consented for the study were having their airway examined via US. Cross sectional sonography of the airway was performed to determine the anatomic relationship of the oesophagus relative to the trachea:
- before induction of anaesthesia
- after GA before external airway pressure manoeuvre
- after GA with external airway pressure manoeuvre.
US guided CP was applied on subjects with central oesophagus; CP and PLP were applied on subject with eccentric oesophagus anatomy.
PLP was performed by lateral compression on the eccentric oesophagus by fingertips under US guidance. To standardised the application of CP and PLP, only 2 well trained investigators were allowed to performed the CP and PLP, US scan on airway and patient recruitment. The conduct of trial involved 2 investigators where first investigator provide US scan, and second investigator provide compression of CP or PLP using fingertips guided by the instruction of first investigator.

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
The number of patients with eccentric oesophagus under general anesthesia, successfully occluded by using cricoid and paralaryngeal pressure.
Periodo de tiempo: ultrasound assessment of oesophagus done after general anaesthesia, during application of cricoid pressure, and during application of cricoid and paralaryngeal pressure
|
we are studying the effectiveness of cricoid pressure versus cricoid and paralaryngeal pressure(novel technique) in those patients with eccentric oesophagus under general anaesthesia.
We use ultrasound to determined the position of the oesophagus after patient under general anaethesia ( to group them under central oesophagus and eccentric oesophagus) and also to determine the success of oesophagus occlusion.
