Refeeding Syndrome

Refeeding syndrome occurs in response to reintroduction of nutrition (whether enterally or parenterally) in the malnourished patient.

Rapid electrolyte and fluid Intracellular shifts in response to the surge of insulin brought on by the presence of nutrients which can lead to numerous medical complications and may progress to life-threatening outcomes, including Coma heart failure, and sudden death.

The hallmark biochemical feature of refeeding syndrome is hypophosphatemia. However, the syndrome is complex and may also feature abnormal sodium and fluid balance; changes in glucose, protein, and fat metabolism; thiamine deficiency; hypokalaemia; and hypomagnesaemia.

Prevention and management of refeeding syndrome

To ensure adequate prevention, the NICE guidelines recommend a thorough nutritional assessment before refeeding is started.

Recent weight change over time, nutrition, alcohol intake, and social and psychological problems should all be ascertained.

Plasma electrolytes (especially phosphate, sodium, potassium, and magnesium) and glucose should be measured at baseline before feeding and any deficiencies corrected during feeding with close monitoring.

For decades, the key to preventing the syndrome was believed to be lower-calorie refeeding with cautious advancement. preventing the syndrome

The NICE guidelines recommend that refeeding is started at no more than 50% of energy requirements for the 1^st 2 days in " patients who have eaten little or nothing for more than 5 days.” The rate can then be increased if no refeeding problems are detected on clinical and biochemical monitoring.

The prescription for people at high risk of developing refeeding problems should consider:

·      starting nutrition support at a maximum of 10 kcal/kg/day, increasing levels slowly to meet or exceed full needs by 4 to 7 days.

·    using only 5 kcal/kg/day in extreme cases (for example, BMI less than 14 kg/m2 or negligible intake for more than 15 days) and monitoring cardiac rhythm continually in these people and any others who already have or develop any cardiac arrythmias.

·     restoring circulatory volume and monitoring fluid balance and overall clinical status closely.

·     providing immediately before and during the first 10 days of feeding: oral thiamin 200 to 300 mg daily, vitamin B co strong 1 or 2 tablets, 3 times a day (or full dose daily intravenous vitamin B preparation, if necessary) and a balanced multivitamin or trace element supplement once daily.

·   providing oral, enteral or intravenous Maintenance requirement of potassium (likely requirement 2 to 4 mmol/kg/day), phosphate (likely requirement 0.3 to 0.6 mmol/kg/day) and magnesium (likely requirement 0.2 mmol/kg/day intravenous, 0.4 mmol/kg/day oral) unless pre-feeding plasma levels are high; pre-feeding correction of low plasma levels is unnecessary.

Pediatric Umbilical Hernia

 Pediatric Umbilical Hernia

Etiology

Umbilical hernia in children results from incomplete closure of the fascia of the umbilical ring, through which intraabdominal contents may protrude.

 After separation of the umbilical cord, usually, the ring undergoes spontaneous closure through the growth of the rectus muscles and fusion of the fascial layers.

A failure or delay in this process leads to the formation of an umbilical hernia.

 The exact etiology is unknown, but usually, occurs through the umbilical vein component of the ring.
