This study evaluates the effectiveness of ultrasound in term pregnant patients posted for elective lower segment cesarean sections and compared them with non pregnant females posted for elective surgeries.
There is increased risk of aspiration in pregnancy due to various reasons i.e. increased progesterone levels, decreased motilin levels and distortion of gastric antrum due to gravid uterus.Ultrasound was proposed to be point of care tool, to assess risk stomach. A comparison with respect to the effectiveness of ultrasound was made in this study. The visibility of gastric antrum by ultrasound in term pregnant females posted for elective lower segment cesarean sections was compared with non-pregnant females posted for elective surgeries.
The secondary aim of the study was to compare the gastric antrum in either groups qualitatively and quantitatively.
