In an emergency setting when rapid transfusion is needed discount 60mg mestinon mastercard, an easy estimate of required transfusion volume is 10cc per kilogram cheap 60 mg mestinon free shipping. A more accurate estimate can be obtained using the following equation: Volume of cells cc Estimated blood volume cc ( Desired Actual hematocrit change Hematocrit of packed red blood cells where the blood volume is estimated using Table 35 discount mestinon 60mg with visa. Regardless of the estimated volume, packed red blood cells are administered at a rate of about 2 to 3cc/kg/hour. In small infants, the response to transfusion is evaluated after every 10cc per kilogram volume in order to evaluate the need for additional transfusion and to avoid excessive transfusion. The volume of platelet transfusion depends on the type of platelets that are used. The platelet-rich plasma then is separated into a unit of fresh frozen plasma and a unit of platelets (about 50cc). These come from a single donor and are obtained from donors by having their blood cir- culated through a machine that separates the platelets and returns the rest. This method results in a platelet preparation with a volume of about 200 to 250cc per donor and is the equivalent of 6 to 8 random donor units. The advantage of using pheresed platelets is that the recip- ient is exposed to only one donor. For pheresed platelets, one-fourth unit can be given to a 5- to 25-kg patient, one-half unit to a 25- to 50-kg patient, and 1 unit to a nearly adult-sized teenage patient. Estimate Fluid Status after Surgery Monitoring of volume status in children in the perioperative period also is highly dependent on the patient’s weight. Urine output is noted in cc per kilogram per hour and compared to the general guide- lines shown in Table 35. Diapers can be weighed to estimate urine volume, which is useful in avoiding the potential trauma of bladder catheterization in small infants and children. Other sources of fluid output also are best evaluated, correcting for the child’s weight (Table 35. Although each of these represent only estimates of expected output, it is useful to use these values when evaluating initial losses and when following ongoing losses. Correct Dosing of Medications Medication dosing also is critically dependent on the child’s weight. Because seemingly small differences may lead to overdosing in a child, it is important that attention be paid to accurate dosing in children. Many children’s hospitals have developed fail-safe mechanisms, such as administration forms, pharmacy verification, and double-checking protocols, to avoid inaccurate dosing of medications. Only pediatric medication manuals should be used to dose medications given to the child in the postoperative period. Care of the Pediatric Surgical Patient 643 hospitals, it is useful to note the patient’s weight and the dose on a per kilogram basis on the patient order sheet whenever a new medication or new dosage of a medication is given. During fetal development, infancy, and childhood, rapid changes occur in physiology that usually are not observed in adult life. The unique physiology at each stage of development accounts for the occurrence of many diseases predominant in specific groups, such as necrotizing enterocolitis in premature infants, intussusception in toddlers, and appendicitis in older children and teenagers. The wide variations in physiology and the diversity of diagnoses that result from these changes account for the appeal of practicing pediatric surgery, but they can be an initial source of frustration for the student with initial experience only with adult patients. The use of principles for manag- ing adults in the perioperative period frequently is not helpful for the pediatric surgical patient. Using principles that recognize the unique- ness of each stage of development can simplify the approach to the pediatric surgical patient. To understand a generalized approach to evaluat- ing newborns with intestinal obstruction. To be able to give a differential diagnosis for the causes of neonatal intestinal obstruction and to understand the general principles for treatment. Case You are asked to evaluate a 12-hour-old newborn male infant because of bilious vomiting. Polydramnios and a dilated stomach were noted on serial prenatal ultrasounds, but amniocentesis was not performed. The infant was born at 36 weeks by vaginal delivery to a 35-year-old mother without complication. The infant has been irritable and has vomited dark-green bilious material with each of two attempts at feeding. The infant is noted on examination to have findings consistent with trisomy 21 (Down syndrome) including poor muscle tone, oblique palpebral fissures, epicanthal folds, and abnormally shaped ears. The abdominal examination shows epigastric prominence, but it is other- wise normal, and the anus is in a normal position and appears patent. Introduction A diverse range of diseases can lead to intestinal obstruction in the newborn infant (Table 36. While the etiology, pathophysiology, and treatment of surgical causes of intestinal obstruction in the neonate are varied, it is helpful to use a diagnostic approach that considers 644 36. Neonatal Intestinal Obstruction 645 each disease, particularly since more than one may be present. Because several of these diseases can be life-threatening or lead to lifelong disability if not treated promptly, the diagnostic evaluation should be rapid and follows a series of logical steps (see Algorithm 36. Presentation The initial presenting signs and symptoms of neonatal intestinal obstruction are varied and include frothy oral secretions, poor feeding, bilious or nonbilious vomiting, abdominal distention, and absent or delayed passage of meconium. The timing and nature of each pre- senting finding can provide very useful information about the etiology of the intestinal obstruction. Proximal intestinal obstructions, such as esophageal atresia or congenital causes of gastroduodenal ob- struction, usually present within the first 24 to 48 hours of life. Distal obstructions, such as ileal or colorectal atresias, may present a few days after birth, while functional obstructions, such as Hirschsprung’s disease, may present as late as a few weeks to years after birth. Esophageal atresia presents with prominent oral and upper airway findings, including excessive frothy oropharyngeal secretions and repeated episodes of coughing, choking, or cyanosis that become apparent with attempts at feeding. Although poor feeding eventually is a feature of all causes of newborn intestinal obstruction, this finding may be delayed in patients with distal gastrointestinal tract or func- tional obstructions. The absence of bile in the emesis suggests that the level of obstruction is proximal to the ampulla of Vater. Bilious vomiting suggests a more distal obstruction and is an important finding, since about 25% of neonates with this finding eventually require abdominal surgery. In the case presented above, bilious emesis suggests an obstruction that is distal to the ampulla of Vater. The presence and timing of onset of abdominal distention also can provide useful diagnostic information. Abdominal distention that is present at birth can result from antenatal intestinal obstruction and perforation usually due to volvulus, intestinal atresia, meconium ileus (meconium peritonitis), an intraperitoneal mass (choledochal cyst, mesenteric cyst, duplication cyst, hydrometrocolpos, or ovarian cyst), a retroperitoneal mass (hydronephrosis or renal mass), or ascites. Although epigastric fullness may be observed, generalized abdominal distention usually does not occur in neonates with gastroduodenal obstruction. Abdominal distention, however, can develop in the first hours after birth in neonates with esophageal atresia due to air passing through a concomitant tracheoesophageal fistula, particularly if the infant is ventilated mechanically. Neonates with malrotation and midgut volvulus also may develop abdominal distention due to dilatation of a closed segment of bowel distal to the usual site of duodenal obstruction. Abdominal distention usually is delayed in those infants with more distal or functional obstructions and may appear 24 hours or later after birth.
