ABSTRACT
Objective • To observe the correlation between streamlined liner of pharynx airway (SLIPA) and gastric insufflation. Methods • Seventy patients who underwent elective general anesthesia in Jiading District Central Hospital Affiliated to Shanghai University of Medicine & Health Sciences from September 2017 to May 2018 were included. They were randomly divided into SLIPA group (S group, n=35) and endotracheal tube group (T group, n=35). The gastric antrum ultrasonography was performed at four time points before induction, immediately after intubation (insertion of laryngeal mask), before extubation (laryngeal mask), and immediately after extubation (laryngeal mask), to measure the cross sectional area (CSA) of gastric insufflation. Gastric intake was assessed by ultrasonic measurement of CSA and "comet tail sign" in ultrasound imaging. Pulse oxygen saturation (SpO2), end-tidal pressure of carbon dioxide (PETCO2), peak inspiratory pressure (PIP) and CSA were recorded and compared at the corresponding time points. Results • There was no significant difference in gastric insufflation rate between the two groups during anesthesia (P=0.894). There was no significant difference in SpO2 at each time point between the two groups (all P>0.05). At the end of surgery, PETCO2 in group S was significantly higher than that in group T (P=0.000). Conclusion • Compared with endotracheal tube, the SLIPA does not increase gastric insufflation during general anesthesia.
