Abstract :

AIMS AND OBJECTIVE The aim of our study was to investigate the functional impact of cricoid and paralaryngeal pressure respectively, on the outer anteroposterior (AP) diameter of the upper oesophagus at the cricoid cartilage level.

METHOD The study was conducted by dividing subjects into two groups.In both groups , the image of the oesophagus was captured and stored in the system‘s memory.

Group 1 [n=30]Cricoid pressure was applied by one of the two anaesthetists .One anaesthetist localised the cricoid cartilage between the thumb and middle finger and applied gradual backwards pressure with the index finger until 30 N was achieved

Group 2[n=30] Ultrasound imaging was performed on subjects placed in the supine position with the head extended and images were taken with pressure applied by the ultrasound probe and images taken . .

RESULT : It was seen that localization of oesophagus was mostly on the left side. Successful compression was seen in 75% of cases in manual classical CP whereas it was 100% in ultrasonography method. Classical CP method was also associated with more complications like tissue edema, aspiration due to inadequate compression etc.

CONCLUSION : It was found that CP does not effectively reduce the AP diameter of the oesophagus. Successful compression was seen in 75% of cases in classical CP whereas it was 100% in ultrasonography method. Classical CP method was also associated with more complications .Therefore it was concluded that use of ultrasound for oesophageal compression is a superior method.
