- Brief Summary
The antrum and body of the stomach can be assessed sonographically to determine the kind and amount of gastric content (gas, fluid, or solid).The gastric antrum provides the most accurate quantitative data on the gastric volume. The antral cross-sectional area showed a nearly linear correlation with contents of up to 300 ml especially, in the right lateral decubitus position.
Based on the facts that the predetermined fasting intervals in TBI patients is unreliable and it is possible to identify and measure gastric volume with USG, we hypothesize that POCUS will aid in the identification of decreased gastric emptying and risk of aspiration during induction of anaesthesia. Consequently, we plan to conduct a prospective observational study to evaluate the incidence of delayed gastric emptying and residual gastric volume in patients with isolated TBI undergoing emergency neurosurgery under general anaesthesia.
In addition elevated ICP can also detected by measuring Optic nerve sheath diameter (ONSD) using 2D-USG. The intracranial subarachnoid space extends to and around the optic nerve. Hence, any changes in ICP will be reflected around the optic nerve as well. The measurement of Optic nerve sheath diameter(ONSD) using POCUS is one such promising modality supported by the literature.
Methodology:
After getting approval from Institute Ethics Committee (IEC), followed by trial registration with the Clinical Trials Registry of India (CTRI) patients will be enrolled in the study. All patients with isolated moderate (GCS≤12) to severe (GCS≤8) TBI scheduled for neurosurgery under general anaesthesia will be evaluated for inclusion and exclusion criteria and if found suitable, will be enrolled in the study. A written informed consent will be obtained from the legal heir of the patient.
In the preoperative area, demographic data of the patient which include age, gender, approximate height and weight and BMI, existing comorbidities, details about the injury and its diagnosis, time and duration after which the patient is presenting for surgery, fasting time, last meal taken before the injury, and GCS will be noted. USG of stomach optic nerve sheath will be carried out:
A) USG assessment of gastric antral content (empty, fluid, solid).
B) USG assessment of gastric antral volume.
C) USG assessment of ONSD will be performed as an indirect measurement of ICP.
