Gastric Ultrasound for Airway Management in Emergency Patients
Sponsor: Indonesia University
Summary
This prospective observational cohort study evaluates the association between gastric residual content and volume, assessed by point-of-care gastric ultrasound (PoCUS), and the choice of airway management technique (Rapid Sequence Intubation vs. non Rapid Sequence Intubation) in adult emergency surgical patients at Rumah Sakit Cipto Mangunkusumo (RSCM). Aspiration risk in emergency patients is a critical concern, and this study examines whether objective ultrasonographic findings change clinical decision-making compared to traditional clinical assessment alone.

Preoperative Gastric Point-of-Care Ultrasound (PoCUS)
Gastric antrum ultrasound performed using a low-frequency transducer (2-5 MHz; SonoSite M-Turbo or Lumify Philips) in the supine position before anesthetic induction. The antrum cross-sectional area (CSA) was measured during the relaxation phase between two peristaltic contractions, calculating cranio-caudal (CC) and antero-posterior (AP) diameters. Gastric residual volume (GRV) was calculated using the Perlas formula: GV = 27.0 + 14.6 × CSA - 1.28 × age (years). Gastric content was classified as empty, liquid, solid, or mixed. Aspiration risk was categorized as high (GRV ≥1.5 ml/kg or solid content) or low (GRV \<1.5 ml/kg or empty).
