Abstract
OBJECTIVE To establish the effect of an audible airleak (around an endotracheal tube) on oxygen consumption (VO2) measurements in pediatric ICU patients. DESIGN Prospective trial comparing VO2 measurements before and after deflation of the endotracheal tube cuff. SETTING Pediatric ICU in a large pediatric tertiary care center. PATIENTS Twenty critically ill infants and children receiving mechanical ventilatory support via cuffed endotracheal tube. INTERVENTIONS Deflation of endotracheal tube cuff. MEASUREMENTS AND MAIN RESULTS The presence (group 1, n = 9) or absence (group 2, n = 11) of an audible airleak with the cuff deflated was confirmed by two independent observers. The percent difference in VO2 was calculated for both groups using the following formula: ([VO2 cuff up - VO2 cuff down]/VO2 cuff up) x 100. An audible airleak associated with cuff deflation (group 1) caused a significant (p = .0012) reduction of VO2 by 45.6% (mean difference in VO2 = 45.6%). In contrast, with no audible airleak after cuff deflation (group 2), only minimal changes in VO2 (mean difference in VO2 = -0.4%) were observed. CONCLUSIONS These data suggest that if no audible airleak is detected, VO2 determined by indirect calorimetry may be reliably measured in infants and children with a noncuffed endotracheal tube.

Abstract
Iatrogenic injury to the aorta or its major branches during nephrectomy for Wilms' tumor in children is rarely reported but may be more common than is currently acknowledged. We identified four patients with ligation of the superior mesenteric artery (SMA) that occurred during nephrectomy for nephroblastoma and another child in whom SMA thrombosis developed postoperatively. All of the tumors were on the left side. Interruption of the SMA was recognized intraoperatively in all four children, and primary repair was done. In three patients, appearance of the bowel remained normal before repair of the injury. Three of the arteries were repaired by primary reanastomosis, and one was joined with an interpositioned hypogastric artery graft. None of these patients had gastrointestinal complications postoperatively. In the fifth patient, SMA thrombosis developed after repair of an aortic tear during nephrectomy. This patient required subsequent small bowel resection for bowel infarction and died in the perioperative period. Every surgeon treating children with Wilms' tumor should be aware of the possibly distorted vascular anatomy and take precautions to avoid such a significant injury. Attempts at early ligation of the vessels may not be justified until the renal vasculature is clearly identified.

Abstract
Despite several reported cases, the association of Hirschsprung's disease and intestinal atresia is not widely recognized. We describe three patients with jejunoileal atresia who all had a preoperative barium enema that failed to show a transition zone. All three patients developed an anastomotic leak of the atresia repair, and required a temporary diverting enterostomy. Two patients had total colonic Hirschsprung's disease and in one, the transition zone was in the midtransverse colon. Histological examination of the appendix at the time of repair may be helpful in patients with small intestinal atresia. In patients who develop an anastomotic breakdown, rectal biopsy should be performed to rule out Hirschsprung's disease.

Abstract
Neonates with congenital diaphragmatic hernia (CDH) are known to be susceptible to stress-induced persistent pulmonary hypertension (PPHN). Congenital cystic adenomatoid malformations (CCAMs) may also present as respiratory distress in the newborn. Intubation and mechanical ventilation cause clinical deterioration because of air trapping within cystic spaces; these patients require prompt lobectomy. PPHN has not been commonly associated with CCAM. Three patients with CCAM were encountered who developed PPHN postlobectomy. Three newborns, 36 to 38 weeks' gestation, presented with respiratory distress. Two had diagnosis of thoracic tumors on fetal ultrasound (22 and 33 weeks). Chest x-ray at birth confirmed cystic intrathoracic tumors in all and they underwent immediate thoracotomy and lobectomy (1 right upper, 1 left lower, 1 left upper). The patients were stable for 4 hours to 5 days postoperatively and then developed findings consistent with PPHN by cardiac echocardiography and required extracorporeal membrane oxygen (ECMO) support. ECMO was required for 66.5 to 120 hours. Each patient was successfully weaned to conventional ventilatory support. The clinical course of these patients was similar to those with CDH who undergo immediate surgery. The stress of surgical intervention combined with hypoxia and hypercarbia stimulates a hyperactive pulmonary vasculature and the development of PPHN. ECMO provides an effective adjunct to support patients with PPHN on the basis of congenital cystic adenomatoid malformations.

Abstract
Extragonadal yolk sac tumors (YSTs) are uncommon and YSTs of the liver are exceedingly rare, with only three reported cases in the literature. A case is described of primary YST of the falciform ligament extending into the left lobe of the liver in a 14-month-old boy. This is the first reported case of primary YST arising within the falciform ligament. The patient underwent an exploratory laparotomy after presenting with hemoperitoneum. An extremely friable and necrotic tumor was found extending from the falciform ligament into the liver. The tumor was debulked and the patient received 5 months of chemotherapy employing a modified Einhorn regimen. After a partial response to chemotherapy the patient had a second-look laparotomy, at which time a left hepatic lobectomy and en bloc resection of the falciform ligament was performed in order to remove residual tumor. At the present time the patient has no signs of metastases and is alive and well 2 years after his presentation.

Abstract
Twenty-one neonates with severe respiratory failure, who met criteria in this center for extracorporeal membrane oxygenation (ECMO), underwent echocardiographic examinations to assess the role of cardiac dysfunction in determining the need for ECMO. The echocardiographic indexes of function included peak aortic and pulmonary flow velocity, aortic and pulmonary acceleration, shortening fraction, velocity of circumferential fiber shortening, right ventricular output, and left ventricular output. Patients were offered a staged treatment protocol using high-frequency oscillatory ventilation (HFOV), followed by ECMO if failing HFOV rescue. Nine patients demonstrated progressive deterioration and required ECMO (group 1); 12 patients recovered without ECMO (group 2). There were no significant intergroup differences in AaDO2, age, weight, gestational age, inotropic support, mean airway pressure, systemic blood pressure, or arterial blood gas parameters. Group 1 had significantly lower pulmonary and aortic peak flow velocities, lower pulmonary acceleration, lower shortening fraction, and lower velocity of circumferential fiber shortening (P less than .05). We found that values for peak pulmonary velocity less than 0.70 m/s with pulmonary acceleration less than 14 m/s2 would predict the need for ECMO in 7 of 9 group 1 patients and recovery without ECMO in 11 of 12 group 2 patients (P less than .01, Fisher's Exact test). We conclude that on initial echocardiographic evaluation, cardiac performance was impaired in those patients who subsequently required ECMO compared with a group of patients with similar severity in gas exchange who recovered without ECMO. We speculate that echocardiographic assessment of cardiac performance in ECMO candidates may prove useful in prediction of the subsequent need for ECMO or expedient transfer to an ECMO center.

Abstract
Lung biopsy tissue from eight infants with chronic lung disease was evaluated for the presence of Ureaplasma urealyticum. Specimens from four infants grew the organism. Pleural fluid cultures matched lung tissue but tracheal cultures were negative in two babies with positive lung tissue. There were no distinguishing pathologic findings in the four culture-positive infants which could be used to identify them vs. the culture-negative infants. Three culture-positive infants improved clinically after therapy directed at Ureaplasma even though two remained culture-positive. Ureaplasma grows in lung tissue of infants with chronic lung disease, it does not demonstrate any specific standard pathologic findings and tissue cultures do not match endotracheal cultures.

Abstract
Present surgical alternatives for pediatric tracheobronchomalacia are limited and associated with many potentially undesirable complications. The feasibility of different intraluminal expandable endotracheal stents for the treatment of surgically induced tracheomalacia was analyzed in 27 piglets. A potentially fatal tracheomalacia was surgically created. Either a stainless steel "zig-zag" stent or a woven polymeric stent was then implanted. Tracheal patency, mucosal function, histopathologic respiratory tract changes, and effects of the stent on esophageal motility were evaluated over a 16-week period. Piglets with steel stents uniformly experienced intense inflammation leading to tracheal dysfunction and death. Piglets with polymeric stents experienced minimal respiratory symptoms. Expandable polymeric endotracheal stents alleviate surgically induced piglet tracheomalacia, were easy to insert, allowed for tracheal growth, and reduced the need for high-risk surgical procedures with prolonged ventilatory support.

Abstract
Packed erythrocytes are frequently reconstituted with crystalloid during rapid infusion. Dilution of whole blood with calcium containing solutions, such as Ringer's lactate has been cautioned against, citing possible clot formation because of chelation of the citrate anticoagulant. We studied the compatibility of Ringer's lactate solution and citrate phosphate dextrose (CPD)-preserved packed erythrocytes to evaluate the safety of using Ringer's lactate solution as a diluent in the emergency setting. Aliquots of CPD-preserved packed erythrocytes were diluted with either Ringer's lactate or normal saline solutions in ratios between 5:1 to 1:20 (packed erythrocyte to crystalloid), incubated at room temperature or 37 degrees centigrade and examined for clot formation at intervals up to two hours. Although clotting occurred at dilutions of 1:1 (packed erythrocytes to Ringer's lactate solution) and beyond, no clot formation occurred in the clinically relevant dilutions between 5:1 and 2:1. Thirty-two additional units of CPD-preserved packed erythrocytes were diluted to hematocrit values of 35, 45, 55 or 65 per cent and passed through a 170 micron filter. Flow rates of packed erythrocytes diluted with Ringer's lactate and normal saline solutions were compared. There was no difference in flow rates between packed erythrocytes diluted with Ringer's lactate compared with normal saline solutions. Ringer's lactate solution can be safely used as a packed erythrocyte diluent in patients requiring rapid blood transfusions.

Abstract
We have recently treated two cases of anastomotic obstruction after side-to-side stapled enteroanastomosis. Complete obstruction of a stapled small-bowel anastomosis has not been reported to our knowledge. The mechanism of the obstruction appears to be the healing together of the cut edges of viable bowel beyond the inverted stapled lines. An alternative method of constructing the functional end-to-end enteroanastomosis that is offered is intended to prevent the occurrence of postoperative anastomotic obstruction.

Abstract
Use of prosthetic materials for long-segment tracheal reconstruction has been limited owing to infection, graft migration, ingrowth of fibrous tissue, and stenosis. Polytetrafluoroethylene (PTFE) is flexible and porous, and it may resist infection more than previously used materials. We evaluated PTFE for use in long-segment tracheal reconstruction. A 5-cm segment of trachea was resected in 9 dogs and replaced with a 20-mm reinforced PTFE graft using 4-0 Vicryl sutures. In 2 control dogs, one tracheal arch was resected and a primary anastomosis was performed. The animals were followed up with weekly bronchoscopy and endoscopic photography. Euthanasia was performed at 16 weeks or when signs of respiratory distress developed. At postmorten examination, the anastomoses were examined grossly and with light and scanning electron microscopy. In all 9 dogs that underwent tracheal replacement with PTFE, granulation tissue developed at the anastomoses resulting in airway obstruction after 3 to 8 weeks. No epithelial growth occurred over the graft between the anastomoses. The control animals did well. We conclude that granulation tissue formation at the anastomosis and the lack of respiratory epithelial ingrowth across the graft makes PTFE unsuitable for long-segment tracheal reconstruction.

Abstract
In cases of severe respiratory failure, cardiopulmonary bypass has been used as support until cardiac and pulmonary recovery occurs. We report the Wilford Hall USAF Medical Center experience with extracorporeal membrane oxygenation (ECMO) and its associated complications. From July 1985 to March 1989, 57 neonates were placed on membrane oxygenators. The overall survival was 79%. Technical complications encountered included catheter-related problems, mechanical complications of the pump apparatus, and hemorrhage. Hemorrhagic complications were the most frequent and devastating complications encountered. Intracranial hemorrhage accounted for six deaths associated with bypass. Extracorporeal membrane oxygenation is successful in significantly improving survival of neonates whose predicted mortality approaches 100% with conventional treatment. The rate of infant mortality using the membrane oxygenator is not affected by technical complications related to catheter position, mechanical problems with the circuit, or hemorrhage, excluding intracranial hemorrhage. The major cause of death of infants receiving extracorporeal membrane oxygenation is the underlying disease process leading to cardiopulmonary failure.

Abstract
Experience with 17 open lung biopsies in critically ill premature neonates was reviewed. Despite their small size, prematurity, and near maximal ventilator requirements, the infants suffered no significant complications. In three cases, an infectious agent was identified. In one case end-stage lung fibrosis associated with persistent (greater than 3 months), severe respiratory failure prompted termination of support. In the remainder of the cases, definitively ruling out infection allowed the confident trial of a course of steroids in an attempt to treat bronchopulmonary dysplasia. Unlike older patients, the definitive diagnosis of no infection in the premature neonate is just as informative as the diagnosis of an infection. Used judiciously, open lung biopsy can be performed in the premature infant with acceptable morbidity and mortality.

Abstract
Respiratory compromise from tracheobronchomalacia in children varies from mild to severe, but can result in either reflex apnea or death. Such severe cases may be unresponsive to aggressive medical management, and surgical options must be considered. Current surgical alternatives are limited and are associated with many potentially undesirable complications. Failure rates are often high. We present two infants with profound life-threatening airway malacia treated by endoscopic placement of a self-expanding endobronchial stent. A description of their anomaly, surgical management, and long-term care is included. The expandable stent may obviate the need for complex high-risk surgical procedures and prolonged ventilatory support.

Abstract
Extracorporeal membrane oxygenation (ECMO) is used in the treatment of reversible pulmonary disease in the newborn. The ECMO program at Wilford Hall USAF Medical Center began in 1985 and to date, 57 patients have been placed on bypass for a mean of 125 hours. The indications for ECMO are severe, prolonged hypoxemia in patients with an estimated mortality of greater than 90% using conventional ventilator support. The major diagnoses in the patients placed on ECMO were meconium aspiration, congenital diaphragmatic hernia, and neonatal sepsis or pneumonia. Overall survival was 79%, or 45 out of 57. The most frequent complications were intracranial hemorrhage as well as hemorrhage from the surgical site. We have found ECMO to be an extremely valuable adjunct in the care of the critically ill newborn and believe it can significantly improve survival in infants with reversible pulmonary disease.

Abstract
Ligation of the brachial artery in the antecubital fossa in children can be performed without limb loss, but the effect on subsequent limb growth is unknown. From 1969 to 1974, brachial artery ligation for insertion of a Scribner shunt was performed in 27 patients with a mean age of 8.4 years (range, 3 to 15 years). We examined 11 patients, all with functional renal transplants, a mean of 15.8 years (range, 13 to 18 years) after ligation. Nine patients had unilateral ligation and two had bilateral ligation. The patients were examined for arm length and circumference, resting blood pressure at the wrist, neurologic function of the arm, and exercise tolerance. A significant difference in resting arterial pressures in the ligated extremity was uniformly noted (mean systolic pressure 106 mmHg versus 123 mmHg in 7 patients, p less than 0.01). Although no patient specifically complained of problems with the ligated side, six of nine patients with unilateral ligation experienced arm discomfort on stress testing. There was no significant difference in limb circumference or length between the ligated and unligated extremity. Ligation of the brachial artery in growing children with renal disease caused diminished resting pressure and mildly decreased exercise tolerance but did not lead to limb loss or subsequent growth abnormalities.

Abstract
Intestinal intussusception, perforation, necrosis, and massive gastrointestinal bleeding are the surgical conditions most often seen in Henoch-Schönlein purpura (HSP). We reviewed the charts of 183 patients who were diagnosed with HSP at two children's hospitals over a 17-year period. Ten patients underwent laparotomy. Intussusception was the most common surgical lesion. Sequential barium enema and upper gastrointestinal series established the diagnosis of intussusception preoperatively in five of six patients. Two patients developed jejunal perforation and segmental ileal ischemia. Although gastrointestinal bleeding occurred in 52% of patients, the bleeding was self-limiting and no blood transfusion was required. Laboratory data were not helpful in differentiating patients with and without surgical problems.

Abstract
Leiomyomas of the intestine are rarely found in the pediatric population. The authors' review of the literature revealed only three colonic leiomyomas previously described. The authors present the first reported case of a child with lower gastrointestinal hemorrhage secondary to a colonic leiomyoma. Pathologic aspects of intestinal leiomyomas are discussed along with the difficulty in histologic differentiation from leiomyosarcomas. Wide resection is recommended for spindle cell neoplasms of the intestine owing to difficulty in differentiating benign from malignant tumors.

Abstract
We evaluated the effect of early closure of the patent ductus arteriosus (PDA) on cardiac performance in a preterm baboon model of hyaline membrane disease. Eleven baboon fetuses were delivered at 75% gestation, resuscitated, and treated with conventional ventilation. The animals were divided into two groups, and underwent left thoracotomy at 2 hr of age. Group 1 (N = 5) had ductal infiltration with formalin to maintain ductal patency. Group 2 (N = 6) had ductal ligation. Hemodynamic parameters were compared between groups before and after surgical intervention. Examination of cardiovascular function was performed at intervals over a 24-hr period using two-dimensional, M-mode, and pulsed Doppler echocardiography. Ventricular performance was significantly worse in the ligation animals as demonstrated by reduced left and right ventricular outputs and reduced left ventricular shortening. However, pulmonary disease and arterial blood gases were not different. Early ligation was also associated with significantly increased systemic vascular resistance. We conclude that early ductal ligation leads to impaired ventricular performance in the premature primate. We hypothesize that the PDA may protect the immature ventricle by preventing pressure overload during adaptation to postnatal life.

Abstract
Mesenchymal hamartoma of the liver occurs almost exclusively in infancy and childhood, with approximately 140 total cases reported. We report the experience with 18 patients at the Childrens Hospital of Los Angeles (Calif) during the past 35 years. The charts of all patients with mesenchymal hamartoma were retrospectively reviewed. The mean age at presentation was 16 months. Thirteen patients were symptomatic, presenting with increasing abdominal distention. Physical examination revealed an abdominal mass or hepatomegaly. Ultrasonography and computed tomography were the most useful diagnostic tests. Fourteen patients underwent resection; 9 underwent hepatic resection and 5 underwent excision of the tumor only. One patient had marsupialization, 1 underwent a biopsy only, and 2 died of unrelated causes and the hamartoma was found incidentally at autopsy. In all instances, a large cystic mass with well-demarcated margins was found. Three patients were unavailable for follow-up and 13 patients were alive and well 1 month to 24 years (mean, 5 years) after diagnosis. Recurrence or malignant transformation was not noted. A presumptive diagnosis can be made preoperatively by normal laboratory values and a combination of ultrasonography and computed tomography. We recommend excision of the tumor in all patients once the diagnosis is made, with the expectation of complete recovery.

Abstract
To assess the changes in the management of splenic trauma, the charts of all patients with splenic injury, documented either roentgenographically or at operation, treated at the Childrens Hospital of Los Angeles from 1965 through 1985 were reviewed. One hundred and eleven patients with confirmed splenic injury were treated. Forty-one patients were seen during the first decade (1965 to 1975) and 70 during the second decade (1976 to 1985). The majority of patients were boys with a mean age of seven years. All of the patients sustained blunt abdominal trauma. During the first decade, all of the patients who had a recognized splenic injury underwent splenectomy. In the second decade, 44 patients were treated without surgical intervention. Twenty-six of the patients required surgical treatment. Splenorrhaphy was successful in 15; however, splenectomy was required in 11 patients. The patients who required surgical therapy had more complications and required more blood products than those patients who were treated nonsurgically. The overall survival rate was 95 per cent and was similar in both decades. Associated injuries, not the splenic injury, were responsible for the lethal outcome of the nonsurvivors. Although the majority of children with splenic injury can be managed nonoperatively, surgical intervention continues to be necessary in our experience in approximately 38 per cent of the patients with an over-all splenic salvage rate of 85 per cent.

Abstract
To determine the utility of the routine cervical spine radiograph, we reviewed all cervical spine radiographs obtained in pediatric trauma patients over a 2 1/2-year period at the Childrens Hospital of Los Angeles. Records of patients admitted with a documented cervical spine injury over a 20-year period were also reviewed. One hundred eighty-seven children had at least one cervical spine radiograph. Forty-six patients (25 percent) required at least one repeat study in an attempt to see all 7 vertebrae. Thirty-eight children (20 percent) had a second radiograph and 8 patients had a third study, all of which showed no injury. There was only one fracture seen during the 2 1/2-year time period. Of the 16 children admitted over the 20-year period, only 3 sustained an injury below the fourth cervical vertebra (C4), and all were over 8 years of age. All patients with cervical spine injury were either comatose or had symptoms referable to the neck. We conclude that the routine cervical spine radiograph in pediatric trauma is a very low-yield test.

Abstract
All attempts at subclavian venous catheterization by the Pediatric Surgery Service done during a one and one-half year period at the Children's Hospital of Los Angeles were prospectively studied. Catheterization was attempted in 107 patients with a mean age of 9.8 years. Cannulation of the vein was successful 89 times (71 per cent) with the major complications being arterial puncture (8.0 per cent), pneumothorax (2.4 per cent) and abnormal position (12.8 per cent). Fluoroscopy was a valuable adjunct when used, resulting in an 86 per cent success rate. The serious complication rate was similar between left and right-sided attempts, but more catheters were abnormally positioned during right-sided attempts (15.7 versus 5.2 per cent). Percutaneous insertion of subclavian venous catheters can be accomplished in infants and children with low morbidity. Cannulation of the left subclavian vein can be accomplished with a similar success rate and a lower malposition rate than the right side. Fluoroscopy is a useful tool to assist in the correct placement of the catheter.

Abstract
The records of all patients with biliary atresia seen at the Childrens Hospital of Los Angeles during a 14-year period were reviewed. Of the 41 patients who could be evaluated, 32 were treated with trimethoprim and sulfamethoxazole prophylaxis, five were given other agents, and four received no prophylaxis after surgery. At least one episode of cholangitis occurred in nine patients. With one exception, all patients destined to have cholangitis did so within 9 months of surgery. Of the nine patients, five were receiving prophylaxis at the time the disease developed, but two were no longer receiving any prophylaxis. The other two patients in whom cholangitis developed never received antibiotic prophylaxis. In the 24 patients who had a Kasai type of portoenterostomy, cholangitis developed in three of the five (60%) with a Roux-en-Y limb length less than 40 cm and in two of the 19 (10.5%) with limb lengths greater than 40 cm (P less than .02). When performed earlier than 61 days after birth, surgery resulted in adequate bile flow in 64.7% (11/17) of patients who could be evaluated as compared with 31.8% (7/22) for surgery at 61 days or later (P less than .05). Of the patients with adequate biliary drainage 11 had no apparent liver disease, but only two of the patients with poor drainage were free of clinical liver disease. The conclusion from this series is that a combination of timely surgery, intestinal conduit at least 40 cm in length, and subsequent long-term antibiotic prophylaxis favors the best bile flow and reduces the occurrence of cholangitis, resulting in the best outcome.

Abstract
Technological limitations have impeded accurate energy expenditure assessment in critically ill infants and young children. Instead, a predicted energy expenditure (PEE) is derived based on weight, heat loss, activity, growth requirements, and degree of stress. This study compared actual measured energy expenditure (MEE) with conventional predicted values in 20 critically ill infants and children using a validated metabolic cart designed for use in this age group. All patients were studied either within 4 days of major surgery or during an acute disease process necessitating intensive care. All were severely stressed clinically and were studied while mechanically ventilated in a temperature-controlled environment. The study interval ranged from 1 to 12 hr and averaged 4 hr after a stabilization period of 30 min. The mean MEE was significantly lower than the mean PEE (52.2 +/- 16 kcal/kg/day vs 101.8 +/- 17 kcal/kg/day, P less than 0.001) with a mean MEE/PEE of 52.6 +/- 17% (range 26 to 92%). In a subgroup of 7 paralyzed patients, the mean MEE was significantly lower than in the 13 nonparalyzed patients when compared with PEE and predicted basal metabolic rate (PBMR). The coefficient of variance, conventionally recognized to be approximately 15% for PEE, averaged 6.35% for MEE in this study. These data indicate that if PEE is used as the sole guide for caloric repletion in the stressed infant or child, these patients will be substantially overfed.

Abstract
We reviewed the records of all infants hospitalized in the neonatal intensive care unit (NICU) who underwent insertion of a Broviac catheter from July 1, 1984 through August 30, 1985. Eighty-six catheters were inserted in 81 patients. Thirty-one catheters were inserted in the NICU and the remainder were inserted in the operating room (OR). The patient's average weight at the time of catheter insertion was the same in both groups. Fifty-two of the 55 OR catheters (95%) were inserted in the external or internal jugular vein while only 68% of the NICU catheters were placed in the jugular veins. Six of the NICU catheters (19%) and 11 of the OR catheters (20%) developed catheter-associated sepsis with positive blood cultures. The infection rate per catheter day was similar in both groups as was the incidence of catheter occlusion. The NICU catheters were in place for an average of 51 days, and there was an average 46 day lifespan for the OR inserted catheters. Broviac catheter insertion can safely be performed in the NICU without an increase in morbidity. Broviac catheter insertion in the NICU is less costly and saves transportation of the sick neonate to the operating room.

Abstract
Vascular access for hemodialysis in children poses problems not encountered in adults because of the small size of the vessels available. The increasing use of peritoneal dialysis has created a large number of patients who need prompt access for hemodialysis for days to weeks during episodes of peritonitis. There are also occasional patients who have exhausted available fistula sites and still require hemodialysis. To address these problems, we designed a series of catheters for insertion in the subclavian vein. The catheters are stiffer than the Hickman type catheter to allow for higher flow rates without collapse. Seventy-five catheters were implanted in 58 patients with a mean age of 14 years. Twelve catheters were inserted in ten children for long-term (over 3 months) access; they have been in place for a mean of 259 days and used for a mean of 64 dialyses. In two children, the catheter has been the sole site for hemodialysis for over a year. Fifty-eight catheters were implanted in 43 patients for short-term hemodialysis. They were in place for a mean of 29 days and used for a mean of 13 dialyses. The major complications encountered were clotting of the catheter and migration out of position. Four catheters were removed because of infection. These new catheters provide effective hemodialysis for children as small as 7 kg with an acceptable morbidity rate and may be used for extended periods of time if necessary.

Abstract
We report a case of a large iliac artery pseudoaneurysm in a newborn infant following umbilical artery catheterization. The aneurysm was excised and a primary repair was performed with limb salvage and reestablishment of normal blood flow to the foot. While these aneurysms are rare, prompt surgical repair should be performed as soon as the diagnosis is made because the associated mortality is high.

Abstract
Potential long-term complications of radiotherapy and chemotherapy in the pediatric patient with Hodgkin's disease necessitate accurate staging. To determine the accuracy of abdominal computed tomography (CT) and gallium citrate Ga 67 scans in staging Hodgkin's disease, we reviewed the charts of all children with Hodgkin's disease seen at Childrens Hospital of Los Angeles from 1975 to 1985. Patients with pathologically proved stage IV disease (ie, bone marrow involvement) and those who only underwent staging laparotomy were excluded. A total of 40 children underwent staging by laparotomy and staging by abdominal CT and/or 67Ga scan. The CT and 67Ga scans were reviewed by radiologists in a blinded manner and compared with the results of a formal staging laparotomy. Of the 38 patients whose disease was staged with 67Ga scan, disease in ten was understaged and in four overstaged, for a 37% incorrect staging rate. Of the 14 patients whose disease was staged by CT scan, disease in three was understaged and in one overstaged, for a 29% incorrect staging rate. In view of the inaccuracy of noninvasive studies and the impact of incorrect staging on treatment, we recommend that a staging laparotomy be performed in all children with Hodgkin's disease who are not proved to have stage IV disease.

Abstract
The utility of an adjunctive aminoglycoside lavage in the prevention of intra-abdominal abscesses utilizing an experimental rodent model was studied. Peritonitis was created in 115 rats by the intra-abdominal placement of gelatin capsules containing a barium-sulfate, human stool mixture. Four hours later, the animals were re-explored and lavaged with 30 ml/kg of sterile saline. Following the lavage, they were randomized to receive 15 ml/kg of either a 0.2% gentamicin or a normal saline lavage. The animals were then treated with intramuscular gentamicin-clindamycin or saline placebo for nine days. There was no difference in the number of abscesses between the groups receiving systemic antibiotics. The addition of gentamicin to a peritoneal lavage did not decrease the incidence of intra-abdominal infection in animals receiving effective systemic antibiotics.

Abstract
We studied the effectiveness of various nutritional supplements in preventing stress-induced gastric ulcers in rats. Male rats were restrained on a board, divided into nine groups and orogastrically infused with one of four commercial nutritional supplements--25 per cent glucose solution, normal saline solution or antacids. The other groups received either cimetidine or no treatment. The rats, in this study, were sacrificed at the end of four hours, and all ulcers were counted. Any solution providing calories, including 25 per cent glucose solution, afforded significant protection against ulceration. While the antacids were better than no treatment, they were significantly worse than any nutritional supplement. It appears to be that luminal substrates markedly increase the ability of the gastric mucosa of the rat to resist ulceration.

Abstract
We reviewed all cases of omphalitis seen at Childrens Hospital of Los Angeles from 1961 to 1981. One hundred and forty patients were seen and, of these, eight had necrotizing fasciitis. All patients with necrotizing fasciitis acquired omphalitis at home, making the incidence of necrotizing fasciitis over 10% in patients with community acquired omphalitis. Most of the infants appeared relatively well on admission with no fever but had a marked leukocytosis. The disease rapidly spread to involve most of the abdominal wall over a period of several hours to days. Seven of the eight patients died (87.5%). Five patients were operated upon but despite extensive resection of involved tissue, four died within 24 hours of surgery. A polymicrobial flora of both gram positive and gram negative bacteria was recovered in all patients cultured. The high incidence of necrotizing fasciitis following omphalitis in the newborn with its attendant morbidity and mortality mandates close observation of these infants with early surgical intervention if there is any question of the diagnosis.

Abstract
Open drainage of the peritoneal cavity for severe intra-abdominal sepsis has been gaining popularity. We had a patient whose overwhelming intra-abdominal infection did not respond to open drainage but was controlled by frequent immersion in a Hubbard tank. Use of the Hubbard tank should be considered in patients with uncontrolled intra-abdominal infection refractory to standard therapy.

Abstract
Lethal fecal peritonitis was created in 253 rats. The rats were then randomized to receive injections of saline solution or clindamycin and gentamicin. All rats received a saline solution lavage and were then further divided to receive a lavage with saline solution, gentamicin, clindamycin or cefoxitin. At the end of nine days, all surviving rats were sacrificed and examined for abscesses. All groups receiving clindamycin and gentamicin parenterally as well as those receiving a lavage with gentamicin or cefoxitin had a significantly better survival rate than did the control group. There was no difference in the number of abscesses in any group receiving antibiotics. Therefore, in this study, no benefit was achieved from an antibiotic lavage in rats receiving effective parenteral therapy.

Abstract
To study the efficacy of several commonly used peritoneal lavage solutions in the treatment of experimental fecal peritonitis, lethal peritonitis was created in 100 rats by placing a gelatin capsule containing 0.1 ml of human stool and barium sulfate within the abdominal cavity. At reoperation up to eight hours after implantation, the rats had initial lavage with 30 ml/kg of sterile normal saline, followed by 15 ml/kg of one of four treatment regimens, all colored alike. These were 10% povidone-iodine (PVP-I), 1% PVP-I, 0.1% kanamycin, and sterile normal saline. A fifth group did not receive a second lavage. All survivors were sacrificed on the ninth day, at which time the study was unblinded. Twelve hours postoperatively there was a significantly greater mortality in the group irrigated with 10% PVP-I (83%) compared to all other groups (0-6%). At nine days, only the kanamycin group had survivors (29%); this was significantly better than any other group.
