ANESTHETIC MANAGEMENT OF TRACHEOESOPHAGEAL FISTULA by Dr.Sravani VishnubhatlaDrSravaniVishnubhatl
Learning Objectives:
Review the clinical presentation of a patient with tracheoesophageal fistula (TEF)
Understand the prevalence of TEF, types, and associated syndrome
Discuss the diagnosis of TEF
Describe the medical and surgical management of TEF
Understand the anesthetic-related implications and develop an anesthetic plan
The neonatal bowel obstruction is suspected based on polyhydramnios in utero, bilious vomiting, failure to pass meconium in the first day of life, and abdominal distension.The presentations of NBO may vary. It may be subtle and easily overlooked on physical examination or can involve massive abdominal distension, respiratory distress and cardiovascular collapse.Unlike older children, neonates with unrecognized intestinal obstruction deteriorate rapidly.
Neonatal bowel obstruction is grouped into two general categories: high, or proximal, obstruction and low, or distal obstruction, both of which are suspected by failure to pass meconium at birth. High obstruction can be suspected based on the double bubble sign. Cases without distal gas are usually related to duodenal atresia, while high obstruction with distal gas need an upper gastrointestinal series because of the need to distinguish duodenal web, duodenal stenosis and annular pancreas from midgut volvulus, the latter being a surgical emergency. Confirmation is ultimately by surgical intervention.
Jejunal and ileal atresia are caused by in utero vascular insults, leading to poor recanalization of distal small bowel segments, a condition in which surgical resection and reanastamosis are mandatory. Hirschsprung disease is due to an arrest in neural cell ganglia, leading to absent innervation of a segment distal bowel, and appears as a massively dilated segment of distal bowel on contrast enema. Surgical resection is necessary for this condition as well. Imperforate anus also requires surgical management, with the diagnosis made by inability to pass the rectal tube through the anal sphincter.[6] Supportive intravenous hydration, gastric decompression, and ventilatory support may be needed due to poor neonatal nutrition resulting from dysfunctional bowel absorption.
A low obstruction is suspected on plain film, but needs follow up with a gastrografin enema, which itself can be therapeutic. The differential for low obstruction is ileal atresia, meconium ileus, meconium plug syndrome and Hirschsprung disease. In cases of meconium ileus or ileal atresia, the colon distal to the obstruction is hypoplastic, usually less than 1 cm in caliber, as development of normal colonic caliber in utero is due to the passage of meconium, which does not occur in either of these conditions. When diffusely small caliber is seen, it is referred to as microcolon. Radiographs in meconium ileus classically demonstrate a bubbly appearance in the right lower quadrant due to a combination of ingested air and meconium. If, on contrast enema, reflux into the dilated distal small bowel loops can be achieved, the study is both diagnostic and therapeutic, as the ionic contrast medium can dissolve the meconium to allow passage of enteric content into the unused colon.
If contrast cannot be refluxed into the distal small bowel, ileal atresia remains a diagnostic possibility.
With early intervention, morbidity and mortality.

With early intervention, morbidity and mortality.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
3. Congenital Posterolateral Diaphragmatic
Hernia (CDH)
One of most severe conditions of
neonate
Defect in diaphragm during early
fetal development
left side most commonly affected
content of the hernia:
small bowel
colon
spleen
stomach
liver, kidney, tail of pancreatic
4. 【Embryology】
week8～9 ： division of coelomic cavity into the pleural
and peritoneal cavity by the diaphragm; a triangular area
in the posterolateral site was left open.
week10～12 ：herniation occur through this opening into
the pleural cavity at the return of midgut
5. 【pathophysiology】
1、Hypoplasia of the lung
Pulmonary weight (ipsilateral+contralateral)↓
Alveoli number↓
Hypertrophy of the media of pulmonary arteriole
Resistance of the vessels↑
2、Pulmonary hypertension
Abdominal viscera into the thoracic cavity → compression of the
lung, PaO2↓PaCO2↑→ acidosis, hypoxemia（PH<7.30）
→pulmonary vessels spasm →vessel resistance↑, right to left
shunting through patent ductus arteries and foramen
ovale↑→aggravate acidosis and hypoxemia in the body
circulation (fetal circulation syndrome)
8. diagnosis after birth
X-ray film:
•Typical air-filled stomach and bowels in the chest, which
continues into the abdominal cavity.
•Diaphram can not be seen at the affected side.
•Absence or scarcity of intestine in the abdominal cavity
9. Treatment
• Before delivery: cortisone could induce the
maturation of pulmonary tissue
• Preoperative preparation:
（1）mechanical ventilation with pure oxygen
（2）nasogastric tube to decompress
stomach and intestine
（3）semi-supine and inclined to
the ipsilateral side， keep warm
（4） i.v. fluid, correction of acidosis
(5）surgical repair without delay.
