  7. Admission Diagnostics • CXR/ KUB • Normal cardiac silhouette with clear lungs bilaterally • Enteric tube lies in blind ending of upper esophageal pouch approximately T2-T3. • Normal abdominal gas pattern with gas in stomach, small bowel, colon, and rectum- suggestive of fistula • CBC • WBC 12.8, Hgb 14.6, Hct 43.9 • ICU lytes • Na 143, K 5.8, Cl 109, CO2 19.3, BUN/Cr 14/1.0 • ABG • pH 7.48, CO2 30, pO2 106, HCO3 22.4, BE 0 • Blood cultures drawn at referring facility Magidah Kobty RNC SNNP

  8. Primary Admission Diagnoses • Term male, 38.5 weeks gestation • Esophageal Atresia • Tracheoesophageal Fistula • Suspected sepsis secondary to aspiration Magidah Kobty RNC SNNP

  9. Etiology and Pathophysiology of Admission Diagnoses • Occurs in 1:5000 live births • Defect occurs during 4th-5th week of fetal development • Result of incomplete division of foregut into respiratory and digestive portions • ~7% infants have chromosomal abnormality • 5 Different types of TE fistula with esophageal atresia • >70% infants have associated GI, Skeletal or Cardiac defects (Blackburn, 2007) (Martin, 2011)

  10. Etiology and Pathophysiology of Admission Diagnoses • Polyhydramniosnoted in some pregnancies • Most cases not diagnosed prenatally • Infants clinically presentation • Inability to swallow secretions • Excessive drool • Coughing • Respiratory distress • Cyanosis • Pneumonia • Surgical intervention within few days of birth Magidah Kobty RNC SNNP (Martin, 2011)

  11. Etiology and Pathophysiology of Admission Diagnoses 5 Differing types of TE fistula with esophageal atresia • Type A • Pure esophageal atresia • No tracheoesophageal fistula • 8-10% of Cases • Associated with long gap between esophageal segments • Infants with delayed surgery to allow for growth • Feeds via g-button Magidah Kobty RNC SNNP (Gomella, 2013)

  12. Etiology and Pathophysiology of Admission Diagnoses • Type B • Esophageal atresia with a fistula connecting proximal esophageal pouch to trachea • 1% of cases • Type C • Most common type of TEF >75% • Esophagus ends blindly and distal esophagus communicates with posterior trachea (Martin, 2011)

  13. Etiology and Pathophysiology of Admission Diagnoses • Type D • <5% of cases • Fistula connecting the proximal and distal esophageal pouches • Type E • “ H” type fistula (5-10%) • Intact esophagus with fistula connecting to tracheal • No esophageal atresia (Perry et al, 2013)

  14. Etiology and Pathophysiology of Admission Diagnoses • Associated abnormalities with TEF/EA • Found in 50-70% of patients • VATER/VACTERL • V – vertebral/skeletal anomalies • A – anal canal defects • C – cardiac anomalies • TE – TEF • R – renal dysplasia • L – limb defects Magidah Kobty RNC SNNP (Perry et al, 2013)

  15. Initial Plan of Care • Place in preheated giraffe isolette • Attach cardiac monitors and pulse oximeter • NPO • Replogle to low intermittent suction • Vital signs q4 • Daily weight/FOC. Plot weekly length measurements on Monday • Strict intake/output • Glucose level q1 X 2, q6 X 2, then q12 while on IV fluids • D10W + ¼ NS at 80 ml/kg/day via UVC • Admission labs: CBC, lytes, Mg, Ca, Phos, BUN/Cr, Total Bili • CXR/KUB on admission Magidah Kobty RNC SNNP

  16. Initial Plan of Care • Evaluate for VATER/VACTERL • Send chromosomes • Obtain ECHO, Head ultrasound, and Abdominal ultrasound • CBG on admission and prn • Keep head of bed elevated • Consult Surgery • Follow blood culture from referring facility • Continue Antibiotics for 24 hours after surgical repair • Ampicillin 50mg/kg IV Q8 • Gentamicin 4mg/kg IV q24 Magidah Kobty RNC SNNP (Truven Health, 2013)

  17. Hospital Course by Systems • Respiratory • 5/9-5/12: Room air • 5/12: Intubated for surgical repair of type C TEF • 5/13: Extubated to room air • Cardiovascular • 5/9: Echocardiogram showed trivial PDA. Normal biventricular size, wall, and function • Heme • 5/9: Hgb/Hct on admission 14.6/43.9 • 5/12: Minimal blood loss during surgical repair of TEF. Hct after surgery 37.6 • Unremarkable, Infant never required transfusions • GI • 5/9: Abdominal Ultrasound: No acute findings. • 5/12: Surgical repair of Type C TEF. JP drain placed. Transpyloric weighted feeding tube placed • 5/14: Formula feeds started via transpyloric tube • 5/19: Barium Swallow function test showed no extravasation. Mild anastomotic narrowing but no stricture or tight hold up of contrast noted. • 5/20: PO feeds initiated Magidah Kobty RNC SNNP

  18. Hospital Course by Systems • GU • Unremarkable • 5/22 Plastibell circumcision done • CNS • 5/9 Head Ultrasound: No acute findings • Musculoskeletal • No skeletal anomalies identified • Ophthalmology • Unremarkable • FEN Support: • 5/9-5/13 Infant on full TPN/IL support • 5/13-5/15 TPN and feeds • 5/15 Full feeds of ~140ml/kg/day • Infectious Disease • 5/9: Blood culture drawn at referring facility. Infant started on prophylactic antibiotics due to possible aspiration. CBC on admission reassuring. • 5/13: Final blood culture results negative. Antibiotics discontinued, 24 hours after surgical repair of TEF Magidah Kobty RNC SNNP

  19. Hospital Course by Systems • Genetics • 5/9: Chromosomes and microarray drawn to rule out chromosomal anomaly. Results pending • Immunizations • 5/8 Hepatitis B vaccine given • Health Maintenance • 5/12: NBS #1 drawn and sent Magidah Kobty RNC SNNP

  20. Lines Procedures Hospital Course by Systems • 5/9 UVC placement • 5/11 PICC placement in left axillary • 5/16 PICC removed • 5/12 TEF/EA repair • 5/12-5/20 JP drain • 5/22 Circumcision Magidah Kobty RNC SNNP

  21. Medications • Antibiotic Therapy: • Ampicillin • 50mg/kg IV Q 8H • Gentamicin • 4mg/kg IV Q24H • IV Nutrition • TPN/IL • Erythromycin eye ointment • One time dose of 1 ribbon strip per each eye • Vitamin K • One time 1 mg/IM injection Magidah Kobty RNC SNNP (Truven Health, 2013)

  22. Theories and Evidence Based Practice • Treatment and Procedures • Thoracoscopic approach • First successful repair of combined esophageal atresia with TEF in 2000 • Use of flexible bronchoscopy allows intraoperative visualization of repair • Minimally invasive approach compared to posterolateral thoracotomy • Decreased trauma to thoracic cavity • Quicker operating times versus thoracotomy • Acceptable surgical approach for low birth weight infants • Type A fistula repair (pure esophageal atresia) • Long gap between ends of esophagus (>4 vertebral segments) • Delayed repair allows infant to grow • Enteral feeds via g-button (Kastenberg, et al, 2014) (Martin, 2011) Magidah Kobty RNC SNNP (Rothenburg, 2012)

  23. Theories and Evidence Based Practice • Post Operative Care • 5-7 days after repair • Obtain contrast esophagram to check for leaks • May initiate oral feedings if no leak demonstrated • Long Term Complications of TEF/EA repair • Recurrent pneumonia • Obstructive airway disease • Airway hyper-reactivity • Gastroesophageal reflux disease • Esophageal stenosis • 95% Survival Rate • Deaths related to associated major anomalies, infants with VATER/VACTERAL sequence, sepsis, aspiration pneumonia (Al-Salem, et al. 2013) Magidah Kobty RNC SNNP (Martin, 2011)

  24. Family Interactions • Family present at all times, staying the night with infant • Parents are very eager to learn • Attend daily rounds; involved in plan of care • Parents have strong support system with extended family members • Siblings visit daily with extended family Magidah Kobty RNC SNNP

  25. Discharge plan and follow- up • Discharge physical exam and vitals • Discharge fluids – Similac Sensitive ad lib po amounts • Pediatrician appointment made within 3 days of discharge • Follow up appointments made with surgeonand pulmonology • Infant hearing screen passed • Congenital heart screen passed • Infant car seat safety/CPR classes for parents and care givers • Immunizations are current • Circumcision plastibell intact • Parents to room in with infant the night before discharge Magidah Kobty RNC SNNP

  26. Summary • Surgical intervention is necessary • TEF/EA can be lethal if not corrected • Major advancements in surgical repair and technology allowing positive outcome for infants • Necessary interdisciplinary approach from surgeons, neonatologist, nurses, respiratory therapist, and families
