Bowel Puncture During Insertion of a Femoral Central Line in the Emergency Department
Bibliographic record
Abstract
BACKGROUND Central venous catheter (CVC) insertion is commonly performed in the emergency department. The femoral vein is often chosen for insertion of CVCs due to its lower risk for complication. We present a rare complication of bowel puncture during insertion of a femoral CVC in the emergency department in a 46-year-old female. CASE REPORT A 46-year-old female with a history of partial gastrectomy and colostomy was transported to the emergency department after being found unconscious. Despite multiple attempts, intravenous access could not be obtained. The emergency physician proceeded to insert a left femoral CVC to obtain venous access. Ultrasound was not used due to perceived urgency, as well as a bedside assessment that the patient's anatomy was straight forward. Stool-like material was aspirated upon inserting the introducer needle, which was quickly removed. An upright x-ray showed no free air, but due to the patient history, an exploratory laparotomy was performed. A single-side perforation in the mid-sigmoid with a small hematoma along the antimesenteric wall was found. The puncture was over sewn, and the patient recovered well; the patient's initial presentation was ultimately considered to be due to medication misuse. CONCLUSIONS This case highlights the importance of using caution in blind attempts at femoral CVC in patients with prior abdominal surgery. It is also important to note the need to avoid insertion of CVCs without the use of ultrasound or when in a rush. If venous access is needed quickly, peripheral or intraosseous venous access can be obtained much more quickly and safely.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
