Tracheoesophageal Fistula (TEF)

Clinical Presentation

• Polyhydramnios on prenatal ultrasound
• Copious, frothy oral secretions immediately after birth requiring frequent suctioning
• Choking, coughing, and cyanosis with first attempted feeding
• Inability to pass an orogastric/nasogastric tube into the stomach (stops at 10-12 cm in the upper pouch)

Diagnosis and Initial Workup

• Chest/Abdominal Radiograph: Coiled radiopaque feeding tube visible in the upper esophageal pouch
• Presence of air in the stomach/intestine confirms presence of a distal tracheoesophageal fistula (standard EA/TEF presentation)
• VACTERL Association screening: Echocardiogram (for cardiac anomalies and right-sided aortic arch), Renal ultrasound, Spine radiographs

Pre-operative Management

• NPO / strict nothing by mouth
• Place a Replogle tube in the upper pouch connected to continuous dual-lumen low suction to clear secretions and prevent aspiration
• Position infant upright (30-45 degrees) to minimize gastric reflux through the fistula into the lungs
• Avoid intubation/positive pressure ventilation if possible (forces air into stomach, risking gastric rupture and impaired ventilation). If required, place ETT distal to fistula.

Perioperative & Wound Protocol

• Strict optimization of acid-base balance (pH > 7.30) and normothermia (36.5-37.5 C) before surgical transport.
• Pain Management: Morphine infusion 10-20 mcg/kg/hr or Fentanyl infusion 1-2 mcg/kg/hr; utilize FLACC/NIPS scales.
• Avoid excessive traction on bowel or silo structures; inspect mesenteric color Q1H for ischemia.
• Wound care: Sterile saline packing or specialized dressings strictly per Pediatric Surgery direction.
• Do NOT administer nephrotoxic drugs post-op until urine output is > 1.5 mL/kg/hr.

Standardized Discharge & Follow-Up Criteria

• Adequate weight gain explicitly > 15-30g/day over a continuous 3-5 day period.
• Maintenance of temperature in an open crib with standard clothing for 48 hours.
• Successful completion of the 90-120 minute Infant Car Seat Challenge.
• Caregiver successfully completed CPR training, rooming-in, and independent medication administration.
• Referrals placed for High-Risk Infant Follow-Up Clinic, Early Intervention (PT/OT), and appropriate sub-specialists.

Diagnostic & Management Algorithm

• EA/TEF Pre-Op Pathway: [START] Inability to pass NGT, excessive drooling -> [ACTION] NPO, continuous Replogle suction -> [EVALUATE] Echo to rule out Right Aortic Arch -> [GOAL] Surgical ligation and anastomosis
