My opinion


Although cough projectile may be commoner in intubated patient with endotracheal tube being a narrower conduit,[1] non-intubated patient can also generate cough projectile through wider oropharynx. During elective colonoscopy under fluctuating moderate-to-deep sedation levels, profuse regurgitation with or without cough projectile may happen when imperfectly empty stomach’s contents regurgitate secondary to lower gastrointestinal tract insufflation. To prevent oropharyngeal soiling, tracheobronchial aspiration and operating room airspace contamination, endotracheal tube inner diameter-ID-7.0mm can be blindly inserted as a suction catheter ready-for-continuous-suction when connected to suction tubing via straw connector (Figure 2). Endotracheal tube’s soft-tip can lie shallow inside oral cavity if prominent gag reflex is preventing its further advancement inside pharynx until deeper sedation level has set in or profuse regurgitation is warranting aggressive suctioning. Larger ID endotracheal tubes may not ensure adequate suctioning seal with straw connector; additionally, they may potentially risk inadvertent aspiration of straw connector. With bite block keeping patient’s mouth open, the anesthesia provider can consider wearing a headlight for regular oropharyngeal monitoring. Nasal cannula can be easily replaced with Panoramic Oxygen Mask® which allows this suctioning arrangement.[2] When esophagogastroduodenoscope occupies bite block’s central opening, bite block’s side openings may be used for this suctioning arrangement. As patient safety is the primary concern, costs of material may have to relegate to backseat when soft-tipped endotracheal tube ID 7.0mm as a suction catheter costing ~$6 replaces either ineffective Yankauer suction tip outer diameter 6.7mm costing ~$1 or unavailable SSCOR DuCanto catheter ID 6.6mm costing ~$2.[3] Moreover, VivaSight-SL,[4] a costlier endotracheal tube with integrated camera, can monitor and manage impending regurgitation/vomiting in real-time when it is placed inside pharynx as a suction catheter.

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?

For each article Authors/Readers, Reviewers and WMC Editors can review/rate the articles. These ratings are used to determine Feedback Scores.

In most cases, article receive ratings in the range of 0 to 10. We calculate average of all the ratings and consider it as article quality.

Quality=Average(Authors/Readers Ratings + Reviewers Ratings + WMC Editor Ratings)
