DEFINITIONEASOPHAGEAL ATRESIA
It is the failure of the esophagus to form a continuous passage from pharynx to stomach during embryonic development resulting in obstruction in infants normal swallowing routes.
TRACHEO ESOPHAGEAL FISTULA
It is the Abnormal connection between trachea and esophagus or failure of esophagus to separate into two distinct structure .

INCIDENCEApproximately in infants of 3,000-3,500 live
births.Occur Both males and famales, frequently
associated with prematurity.Occur one in 4,000 babies in the united
states is born with esophageal atresia. It is the 25th most common birth defect.

PATHOPHYSIOLOGY
Esophagus developed from first segment of embryonic
gut.During the 4th and 5th week of gestation ,forgut normally
lengthens and separate longitudinally and longitudinal
portion fuse to form parallel channels. Anomalies involving
trachea and esophagus are caused by defective incomplete
fusion of the tracheal folds following separation or altered
cellular growth during embryonic development.

Aspiration of stomach content.Genetic testing. • Molecular genetic testing • Chromosome analysis EA/TEF may be suspected Prenatally by:- • Ultrasound examination • Fetal MRI
![Page 16: Esophageal atresia](https://reader036.vdocuments.site/reader036/viewer/2022081418/5538c041550346bb318b486a/html5/thumbnails/16.jpg)
EA may be detected Postnatally by: •Failure to pass a nasogastric (NG) tube and radiographs that demonstrate coiling of the NG tube the pouch. • Tracheal compression and deviation on plain chest radiographs. • Absence of a gastric bubble on plain radiographs, which may suggest EA without a TEF or EA with a proximal TEF. • Three-dimensional CT scanning.

MANAGEMENTMEDICAL MANAGEMENT
Treatment include:-Maintanance of patient airway.Prevention of pneumonia.Gastric pouch decompression.Surgical repair of anomalies.Supportive therapy.Stop oral intake, start IV fluids.

Maintain supine position.Frequent and continuous suction.Provide respiratory support.Maintaining thermally neutral environment.Genetic Counseling.

AFTER CARE

Cervical Easophagostomy Bauginage Esophageal replacement procedure 1. Colon Interposition. 2. Gastric tube interposition. ET Tube intubation

Complication Of Surgery
Reaction to medicines.Breathing problems.Bleeding. Infection.Collapsed lung(pneumothorax).Food leakage from the area that is repair.Low body temperature(hypothermia).Narrowing of the repaired organ.Re-opening of the fistula.
![Page 24: Esophageal atresia](https://reader036.vdocuments.site/reader036/viewer/2022081418/5538c041550346bb318b486a/html5/thumbnails/24.jpg)
NURSING MANAGEMENTPRE-OPERATIVE CARE Establishment of patient airway. Prevention of further respiratory compromise. Immediate after birth,nurse give the first feeding of plain
water and assist mother while feeding baby to observe any anomalies.
If cyanosis is present it can be resolved by removing secretions from oropharynx by suctioning and by oxygen administration.
Stop oral fluids and start IV fluids. Neonate is kept warm using an incubator or radient warmer. Daily change of cathether (Indwelling double lumen
cathether) to prevent infection.
![Page 25: Esophageal atresia](https://reader036.vdocuments.site/reader036/viewer/2022081418/5538c041550346bb318b486a/html5/thumbnails/25.jpg)
Provide supine position with 30 degree elevation and of head to prevent aspiration ,If there is an atresia but no fistula,infant is placed in head down position to facilitate drainage.
In staged repair gastrotomy tube inserted and left open so that any air entering the stomach through fistula can escape and prevent regurgitation.
![Page 26: Esophageal atresia](https://reader036.vdocuments.site/reader036/viewer/2022081418/5538c041550346bb318b486a/html5/thumbnails/26.jpg)
POST OPERATIVE CARE Elevate gastrotomy tube above the level of stomach so
that gravity helps an emptying of tube contents easily. Infant is returned to radiant warmer. Gastrotomy tube is connected to gravity drainage untill
infant can tolerate feeding. Before oral feedings are initiated chest tubes are
removed. Assist initial attempts of oral feedings . Tracheal suction. Antibiotics are administered.

COMPLICATIONS
Salivary Aspiration.Gastric acid reflux.Congenital heart disease.Gastro intestinal anomalies.Dehydration and electrolyte imbalance.

NURSING DIAGNOSIS PRE OPERATIVE NURSING DIAGNOSISRisk for suffocation related abnormal
opening between esophagus and trachea. Risk for altered parenting related infants
physical defect and environmental factors causing parent infant separation.
Fluid volume deficit related to inability to take oral fluids.

POST OPERATIVE NURSING DIAGNOSISIneffective airway clearance Altered nutritional statusAltered comfort pain
