The Orogastric Tube Guide® as a novel strategy for gastric tube insertion: a prospective, randomized controlled clinical trial
Bibliographic record
Abstract
BACKGROUND: Gastric tube insertion, either orally or nasally, is daily practice in anesthesia and intensive care. "Blind" insertion represents the common conventional method and is associated with low first-pass success and frequent complications. This trial aimed to evaluate the novel gastric tube guide as a rigid conduit in regard to insertion success rate, time required and associated complications versus the conventional "blind" insertion method. We hypothesized that the insertion success rate is higher using the Orogastric tube guide. METHODS: This trial was approved by ethics committee prior to patient recruitment. In a randomized order, anesthetists performed oral insertion of a gastric tube either with the Orogastric tube guide (GTG) or by conventional "blind" technique (CONV) in elective surgical patients. Exclusion criteria were defined as age under 18 years, pregnancy, emergency surgery and patients without indication for tracheal intubation and gastric tube insertion. RESULTS: We examined 151 patients (GTG, N.=71; CONV, N.=80). The success rate was higher with the GTG compared to the conventional method (69/71 (97%) vs. 61/80 (76%); P<0.001). The median insertion time was 25 s (IQR 20-39) using the GTG and 31 s (IQR 24-58; P=0.027) with the conventional method. We found no differences with regard to complications between the groups (P=0.54). CONCLUSIONS: Our findings suggest that the use of the GTG facilitates and fastens orogastric tube placement in anesthetized patients and thereby constitutes a benefit in clinical routine.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
