Pre-anaesthetic sonographic assessment of gastric antrum in parturient scheduled for elective caesarean section - A prospective cross-sectional study.

Background And Aims: Point-of-care ultrasonography (USG) of the gastric antrum can help to evaluate the aspiration risk and improve the safety of anaesthesia. The aim was to assess the gastric antrum in term parturients scheduled for elective caesarean section using bedside USG.

Methods: After obtaining institutional ethics committee approval and written informed consent, 250 term parturients (≥36 weeks gestational age) with body mass index 18.

Comparison of landmark versus pre-procedural ultrasonography-assisted midline approach for identification of subarachnoid space in elective caesarean section: A randomised controlled trial.

Background And Aims: Identification of subarachnoid space in pregnant patients can pose a great challenge to anaesthesiologists. This study was designed to compare conventional landmark technique with pre-procedural ultrasonography-assisted midline approach for identification of the subarachnoid space in elective caesarean section.

Methods: After institute ethics committee approval and written informed consent, 100 parturients scheduled for elective caesarean section under spinal anaesthesia were included in this prospective randomised control trial and divided into Group L ( = 50) (landmark technique) and Group U ( = 50) (ultrasound-guided technique).
