To increase its accuracy, the study should employ similar techniques of tracheal intubation, cricoid pressure
application, head position, and degree of muscle relaxation.
First is to awaken the patient or the second option is to continue anesthesia via mask ventilation or LMA4, while an assistant maintains cricoid pressure
to prevent aspiration during intubation is not recommended in children, as it actually impedes the airway Dr.
By using the thumb and forefinger, the cricoid pressure
will effectively close the esophagus until the cuffed endotracheal tube is established in the patient's airway.
(CP) is proposed as a method to prevent passive regurgitation and the aspiration of stomach contents during induction of anaesthesia in patients with a full stomach (2), and it has become a standard practice amongst anaesthesiologists during a rapid sequence induction/intubation (RSII).
All three patients had full stomachs and thus rapid sequence intubation with cricoid pressure
using xylocaine, propofol, fentanyl, and succinylcholine was performed for induction of general anesthesia, before the procedure.
Pookin, in their study have shown that the cricoid pressure
applied during intubation does not alter the pressor response significantly.
 The use of cricoid pressure
is now controversial and other drugs have been included in modified RSI techniques.
, first introduced by Sellick (1), is widely used as part of rapid sequence induction in patients at high risk of aspiration.
During a recent learning experience I had an opportunity to perform cricoid pressure
on an electronic training aid which measured the efficiency and the accuracy of the pressure applied.
* It is more difficult to determine accurate landmarks on a thick and obese neck, and misapplied cricoid pressure
may permit gastric insufflation and regurgitation and compromise laryngoscopy and intubation.
Often, no one is providing cricoid pressure
to assist with visualization of the larynx during attempted intubation, or coordinating compression and ventilation when needed.
A 90[degrees] counter-clockwise rotation manoeuvre, cricoid pressure
and stylet were used, but insertion of the tube into the vocal cords was impossible.
Succinylcholine with cricoid pressure
. Endotrachial intubation was done with cuffed ET tube and maintained by IPPV with [O.sub.2]; [N.sub.2]O and 0.5-1% isofluranel.
