Internal herniation of small bowel
Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity. If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration, strangulation, or for becoming the lead point of a small bowel obstruction. Internal hernias, including paraduodenal (traditionally the most common pericecal, foramen of Winslow, and intersigmoid hernias, account for approximately.5-5.8 of all cases of intestinal. Internal hernia is an uncommon cause of small bowel obstruction that may be increasing in frequency. Because the clinical diagnosis of internal hernia is difficult, imaging studies such as computed tomography (CT) and small bowel follow through play an important role.

Hernias must be treated surgically. In a hernia repair surgery, the intestines are pushed back into place and the weak point is covered with hernia mesh. The mesh keeps the intestines in place and provides a framework for tissue to grow on, effecting a repair while allowing the site to heal. While waiting for surgery, a patient may be asked to wear a hernia belt which applies pressure to the site, preventing the hernia from getting worse and increasing comfort. In a reducible intestinal hernia, the intestines can easily be pushed back into place during bakerse the hernia repair. Incarcerated hernias involve loops of intestine which become trapped in the hernial sack, and they can become very serious medical problems. If the intestines are allowed to remain incarcerated, they may become strangulated, losing access to their blood supply. The loss of blood will cause the tissue in the intestines to die, causing the onset of gangrene. An untreated intestinal hernia can cause nausea, vomiting, tegen constipation, and other intestinal problems as a result of bowel obstruction caused by the herniation.

Blood Volumes estimates of help during surgical blood loss are: premature 85-100 cc/kg, term 85 cc/kg, and infant 70-80 cc/kg. The degree of dehydration can be measured by clinical parameters such as: body weight, tissue turgor, state of peripheral circulation, depression of fontanelle, dryness of the mouth and urine output. Intravenous nutrition is one of the major advances in neonatal surgery and will be required when it is obvious that the period of starvation will go beyond five days. Oral feeding is the best method and breast is best source. Newborn infants requires 100-200 calories/kg/day for normal growth. This is increased during stress, cold, infection, surgery and trauma. Minimum daily requirement are 2-3 gm/kg of protein, 10-15 gm/kg of carbohydrate and small amount of essential fatty acids. Back to Index,.
The older child needs about 1-2 cc/kg/hr and the adult.5-1 cc/kg/hr. Back to Index. Fluid and Electrolytes Concepts, cellular energy mediated active transport of electrolytes along membranes is the most important mechanism of achieving and maintaining normal volume and composition of fluid compartments. Infants can retain sodium but cannot excrete excessive sodium. Electrolytes requirements of the full-term neonate are: Sodium 2-3 meq/kg/day, potassium 1-2 meq/kg/day, chloride 3-5 meq/kg/day at a rate of fluid of 100cc/kg/24 hrs for the first 10 kg of weight. As a rule of thumb, the daily fluid requirements can be approximated too: prematures 120-150cc/kg/24 hrs neonates (term) 100cc/kg/24 hrs.
Infants 10kg 1000cc 50cc/kg/24 hrs. Special need of preterm babies fluid therapy are: conservative approach, consider body weight changes, sodium balance and ecf tonicity. They are susceptible to both sodium loss and sodium and volume overloading. High intravenous therapy can lead to patent pda, bronchopulmonary dysplasia, enterocolitis and intraventricular hemorrhage. Impaired ability to excrete a sodium load that can be amplify with surgical stress (progressive renal retention of sodium). Estimations of daily fluid requirements should take into consideration: (1) urinary water losses, (2) gastrointestinal losses, (3) insensible arthrose water losses, and (4) surgical losses (drains).

The newborn's body surface area is relatively much greater than the adults and heat loss is a major factor. Insensible water loss are from the lung (1/3) and skin (2/3). Transepithelial (skin) water is the major component and decreases with increase in post-natal age. Insensible water loss is affected by gestational age, body temperature (radiant warmers and phototherapy. Neonatal renal function is generally adequate to meet the needs of the normal full-term infant but may be limited during periods of stress. Renal characteristics of newborns are a low glomerular filtration rate and concentration ability (limited urea in medullary interticium) which makes them less tolerant to dehydration. The neonate is metabolically time active and production of solute to excrete in the urine is high. The kidney in the newborn can only concentrate to about 400 mOsm/L initially (500-600 mOsm/L the full-term compared to 1200 mOsm/L for an adult and therefore requires 2-4 cc/kg/hr urine production to clear the renal solute load.

Tbw is distributed into extracellular fluid (ECF) and intracellular fluid (ICF) compartment. The ecf compartment is one-third the tbw with sodium as principal cation, and chloride and bicarbonate as anions. The icf compartment is two-third the tbw with potassium the principal cation. The newborn's metabolic rate is high and extra energy is needed for maintenance of body temperature and growth. A change in neurofysiologie body water occurs upon entrance of the fetus to his new extrauterine existence. There is a gradual decrease in body water and the extracellular fluid compartment with a concomitant increase in the intracellular fluid compartment. This shift is interrupted with a premature birth.

Neonatal Physiologic Characteristics. Water metabolism, water represents 70 to 80 of the body doen weight of the normal neonate and premature baby respectively. Total body water (TBW) varies inversely with fat content, and prematures have less fat deposits.

An intestinal hernia is a hernia in which the intestines supplements push through the abdominal wall, creating a distinctive lump. The majority of hernias are inguinal hernias, which means that they appear around the groin region. This type of hernia is fairly common, occurring in people of all ages and all levels of physical condition. It is important to seek treatment for an intestinal hernia, as serious complications can develop if the hernia is allowed to persist. The large or small intestine can be involved in a hernia. In both cases, the intestines find a weak point in the abdominal wall and push through it, creating what is known as a hernial sac. The herniation of the intestines can be accompanied by severe pain, and it is usually readily apparent because of the distinctive lump which forms under the skin. People can develop hernias after abdominal surgery, or as a result of severe strain.
