My opinion


Inability to quantify gastric fullness preoperatively can be very frustrating for anesthesiologists. This is especially more so while managing gastrointestinal endoscopies, firstly because gastrointestinal endoscopies are primarily performed under moderate sedation with unprotected airways, and secondly because endoscopy suites have rapid turnovers discouraging routine use of preoperative gastric ultrasound screening for gastric fullness. Moreover, clinical research to prove that preoperative gastric ultrasound can work within endoscopy suites’ time-constraints is difficult to plan. Additionally, there can be healthcare costs if anesthesia plan is routinely changed from moderate sedation to general endotracheal anesthesia to avoid risk of pulmonary aspiration after preoperative gastric ultrasound raises suspicion for incompletely empty stomach. Still, as demonstrated in figure 1, the personal ultrasound images of empty, filled and full antrum can inspire healthcare institutions’ administrators to encourage clinical teams considering preoperative gastric ultrasound to screen their obtunded patients whose severity of preoperative nausea or vomiting cannot be easily quantified. Even though the naivety of clinical teams in appropriately screening gastric fullness with ultrasound may lead to increased incidence of general endotracheal anesthesia for gastrointestinal endoscopies, the opportunity to actually see antrum empty, filled or full in lean or obese patients while differentiating it from bowel, gall bladder and aorta will start serving its core purpose in due course of time. That core purpose for anesthesiologists is to not assume preoperative emptiness of their patients’ stomachs solely based on their patients’ symptomatology when preoperative gastric ultrasound screening can objectively confirm or refute their suspicions regarding pulmonary aspiration risks among their patients.[1-3]

What is article Popularity?

Article popularity is calculated by considering the scores: age of the article
Popularity = (P - 1) / (T + 2)^1.5
Where
P : points is the sum of individual scores, which includes article Views, Downloads, Reviews, Comments and their weightage

Scores   Weightage
Views Points X 1
Download Points X 2
Comment Points X 5
Review Points X 10
Points= sum(Views Points + Download Points + Comment Points + Review Points)
T : time since submission in hours.
P is subtracted by 1 to negate submitter's vote.
Age factor is (time since submission in hours plus two) to the power of 1.5.factor.

How Article Quality Works?
