Burns management
Q) A 45 year old male sustains 30% burns on both legs and anterior abdominal wall. There was mild inhalation injury associated with it. He initially responded well to treatment with IV fluids, Inj Tramadol and enteral feeding.
Three days after the treatment he is having slight tachypnea (30/min) pulse 110/min and BP 98/60. His temp is 97degree F and some areas of partial thickness have converted into full thickness. He is currently on Inj Magnamycin. His platelets are 70ooo, TLC is 17000 and sugar is 200 mg%. What is the next step in management?
a) Continue same management
b) Upgrade the antibiotic and send a fresh culture from skin
c) Treat it as carbon monoxide poisoning
d) Manage in lines of Acute Tubular Necrosis
Burns management involves critical care, intensive phase and rehabilitation. Loss of skin and eschar formation predispose individuals to gram positive, gram negative and fungal infections.
Understanding Duodenal Atresia: Causes, Symptoms, and Treatment

b) It presents soon after birth with non bilious vomiting
c) Pre natal detection of duodenal atresia is common
d) Gastro jejunostomy is the procedure of choice to bypass the obstruction
Understanding Duodenal Atresia in Infants: Key Facts and Diagnostic Insights
Duodenal atresia is a congenital condition that affects newborns, impacting their gastrointestinal (GI) system. While not the most common form of GI atresia, it is a significant condition that requires early detection and treatment. This article delves into the critical aspects of duodenal atresia, including its symptoms, diagnosis, and treatment options.
What is Duodenal Atresia?
Duodenal atresia is a congenital obstruction of the duodenum, the first part of the small intestine. This condition occurs in approximately 1 in 5,000 live births and is associated with other congenital malformations, such as Down syndrome, prematurity, and biliary atresia.
Prenatal Detection of Duodenal Atresia
Early Diagnosis through Ultrasound
One of the most notable aspects of duodenal atresia is that it is commonly detected during prenatal ultrasounds. Advances in antenatal sonography allow doctors to identify most cases before birth, providing an opportunity for early planning and intervention. The typical sign on ultrasound is a "double bubble" appearance, which indicates the presence of fluid-filled areas in both the stomach and duodenum.
Symptoms and Presentation
Bilious Vomiting After Birth
Duodenal atresia typically presents soon after birth, with one of the hallmark symptoms being bilious vomiting. In around 80% of cases, the obstruction is located distal to the ampulla of Vater, allowing bile from the liver to mix with stomach contents, leading to greenish, bilious emesis.
Associated Congenital Conditions
Infants with duodenal atresia may also present with other congenital anomalies, such as Down syndrome, heart defects, or other gastrointestinal malformations like jejunoileal atresia, which is actually the most common type of GI atresia (occurring in 1 in 2,000 live births).
Types of Duodenal Obstructions
Stages of Duodenal Atresia
Duodenal atresia can occur in various forms, ranging from partial obstruction, such as duodenal webs, to complete separation of the duodenum. These different forms dictate the severity of symptoms and the urgency of intervention.
- Duodenal Webs – Thin membranes that partially block the duodenum.
- Stenosis – A narrowing of the duodenum that restricts food passage.
- Complete Atresia – A total obstruction where the duodenum is completely separated.
Diagnostic Features
Double Bubble Sign on Imaging
Postnatally, duodenal atresia is diagnosed through abdominal imaging, with the "double bubble" sign being a classic radiographic finding. This sign appears as two distinct gas-filled bubbles—one in the stomach and one in the duodenum—indicating the obstruction.
Treatment of Duodenal Atresia
Surgical Intervention
The treatment for duodenal atresia is surgical, with the goal of bypassing or removing the obstruction. Contrary to some misconceptions, gastrojejunostomy is not the preferred procedure. Instead, a duodenoduodenostomy is often performed to connect the two ends of the duodenum, allowing normal passage of food from the stomach to the intestines.
Post-Surgical Outlook
With early surgical intervention, the prognosis for infants with duodenal atresia is generally positive. Post-operative care is crucial to ensure proper digestion and prevent complications such as infection or malabsorption.
Bleeding Peptic ulcer
Q) In a 55 year old male with a bleeding peptic ulcer, endoscopy is done. Which of the following findings on endoscopy predicts the highest rate of re bleed?

Free Answer
Answer a
a) Non bleeding vessel IIA - Out of the choices given
Bleeding peptic ulcer is mostly from the posterior surface of the lesion and can be sometimes lethal
Forrest classification is used to grade the risk of re bleeding in peptic ulcers.
According to the stigmata of recent bleed, the chances of re bleed increase.
Endoscopic appearance of bleeding peptic ulcer classification
Ia - Active Spurting Highest 90% chance of acute bleeding peptic ulcer ICD 10
Ib- Active oozing
IIa Non bleeding vessel 50% chance of re bleed
IIB Adherent clot
IIC Flat Pigmented spot
III Clean based ulcer

Q) How to treat a bleeding peptic ulcer? Bleeding gastric ulcer management?
Steps to manage a bleeding peptic ulcer
- Secure two large bore IV lines for fluid and blood products. Evaluate for coagulopathy
- Simultaneous evaluation for source of bleeding and history. Important causes to rule out are chronic liver disease, NSAID use etc
- Simultaneous IV PPI infusion
- Endoscopic control of bleeding peptic ulcer- Thermal coagulation, hemoclips, Adrenaline injections etc
- Operative procedure For Duodenum bleed - Longitudanally opening the anterior wall of duodenum and 3 point suture ligation
- For Gatric ulcer bleeding - depends on the site of ulcer and might require Antrectomy/Partial gastrectomy
