Ultrasound for Comparison of Gastric Antral Volume in Pregnants and Non-pregnants

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Pregnant and non-pregnant females<br>The pregnant females posted for elective lower segment cesarean section and non-pregnant females posted for elective surgeries are scanned by ultrasound in the pre recovery room. The visibility of the gastric antrum is assessed. The qualitative and quantitative assessment is made and is compared. | Other: ultrasound<br>* Sonosite ultrasound (Sonosite, FUJIFILM M-Turbo, made in USA)<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of ultrasound in pregnants and non-pregnants in terms of visibility | The effectiveness is stated in terms of percentage visibility and compared in pregnants and non-pregnants. | October 2016 to October 2017 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Qualitative assessment of Gastric antrum | The qualitative grading is derived and is compared in the pregnants and non-pregnants. | October 2016 to October 2017 | 
| Quantitative assessment of Gastric Antrum | The quantitative data is obtained from the derived formulae and is compared in pregnants and non-pregnants. | October 2016 to October 2017 |
