Pre-Peritoneal Dialysis Peritonitis After Saline Infusion Sonohysterogram in a Patient With an Embedded Catheter: A Case Report
Bibliographic record
Abstract
Rationale: Clear guidelines currently exist regarding antibiotic prophylaxis for patients on peritoneal dialysis (PD) prior to common diagnostic procedures. However, these guidelines do not include patients with subcutaneously embedded PD catheters who are awaiting PD initiation although both these populations share a great deal of risk factors for infections. Issues regarding antibiotic prophylaxis and avoidable infections are bound to keep occurring if physicians are not conscious of the risks of infections shared by all patients suffering from renal failure. Presenting concerns: Two weeks after a saline infusion sonohysterography (SIS), a 48-year-old woman with chronic kidney disease (CKD) G5 ND, type 2 diabetes, a subcutaneously embedded PD catheter, and prior abnormal uterine bleeding presented to the emergency department complaining of nausea, vomiting, diarrhea, weakness, and abdominal pain. The patient received no antibiotic prophylaxis prior to her SIS. Diagnoses: The final diagnosis of peritonitis was established after acute kidney injury, gastroenteritis, and small bowel obstruction were considered and ruled out. A delay in the final diagnosis occurred because of the complex presentation, the fact that the patient had not yet initiated PD, and the presence of concomitant anion gap metabolic acidosis and an acute elevation of the patient's creatinine. Interventions: The patient was started on broad-spectrum intravenous antibiotics when the diagnosis of peritonitis was established. Insulin and intravenous bicarbonate infusions were used to correct the patient's anion gap metabolic acidosis. Surgical debridement of the necrotic subcutaneous tissue and removal of the embedded PD catheter were necessary. Outcomes: The patient's infection resolved completely as did her anion gap metabolic acidosis. The patient had to transfer permanently from PD to hemodialysis for her renal replacement therapy. Teaching points: This case report serves as a good reminder that physicians should keep in mind the possibility of peritonitis in patients with embedded PD catheters. As these patients are also at risk of infections, antibiotic prophylaxis should be used in patients with embedded catheters in the same way it is used for PD patients prior to obstetrical, gynecological, or gastrointestinal procedures.

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.
