An 8-year review of neonates with left-sided congenital diaphragmatic hernia who presented in severe respiratory distress at birth was retrospectively reviewed looking at stomach position, thoracic or abdominal, as a predictor of survivability. Survival was 93% with the stomach below the diaphragm compared with 29% when the stomach was thoracic in location. Stomach position may be an important early in utero predictor of high mortality in neonates with left-sided congenital diaphragmatic hernias.

We successfully treated surgically an elderly patient, a 80-year-old woman, with Bochdalek diaphragmatic hernia. She had intermittent episodes of intestinal obstruction. A preoperative chest roentgenograph revealed a loop of gas-filled bowel in the left chest and elevation of the left diaphragm. CT scanning of the thorax revealed the bowels filled with gastrografin in the left thoracic cavity. She was treated surgically, through transabdominal and then transthoracic approaches. The herniated large bowel was reduced from the thoracic cavity and the hernial sac was excised. The posterolateral defect of the diaphragm, 5 x 6 cm in size was closed with interrupted mattress sutures. The patient has been well without any symptoms 6 months after the surgery. Bochdalek diaphragmatic hernia is the most common problem in infants with risky respiratory distress and high mortality, however it is preferable to carry out surgical treatment for adult patients because of good postoperative results. As a surgical route in the management of Bochdalek diaphragmatic hernia in adults, a transthoracic approach is preferable since it provides easy separation and reduction of herniated bowels from the thoracic cavity and easy closure of the diaphragmatic defect, furthermore there are no other serious gastrointestinal complications which are required specific repair.

To assess the validity of the currently accepted lower weight limit of 2 kg for treatment of neonates with extracorporeal membrane oxygenation (ECMO), we reviewed the outcome of lower birth weight (2.0 to 2.5 kg, n = 29) and higher birth weight (n = 235) for infants treated with venoarterial ECMO at our institution from 1984 through 1990. Newborn infants with congenital diaphragmatic hernia were not included. The mortality rate was significantly greater after venoarterial ECMO in lower than in higher birth weight infants (relative risk 3.45; confidence interval = (1.68, 5.79)). For infants with the diagnosis of respiratory distress syndrome, the mortality rate was 56% (5/9) for lower and 8% (2/25) for higher birth weight infants (p less than 0.01). The most frequent cause of death in lower birth weight infants was intracranial hemorrhage (7/10 deaths). The overall incidence of any neuroimaging abnormality was significantly greater for lower birth weight infants (p = 0.044), primarily because of the higher incidence of major intracranial hemorrhage. Finally, the risk of developmental delay (development quotient less than 70 at 1 to 2 years of age) among survivors available for follow-up was significantly higher among the lower than the higher birth weight infants. These outcome data suggest that further reduction of the current lower weight limit for ECMO should not become standard without prospective research or technologic advances.

Extracorporeal membrane oxygenation (ECMO) provides an adjunct to support of neonates with respiratory distress. The rate of venous drainage is the limiting step to the amount of arterial flow that may be generated during ECMO. We present a 3-kg, 37-week gestation female with congenital diaphragmatic hernia (CDH) whose anatomic venous drainage was insufficient to allow total extracorporeal support. The internal jugular vein was of insufficient size to allow placement of a cannula large enough to support adequate bypass flow. We established minimally acceptable flow by simultaneous caudad and cephalad catheterization of the internal vein. We performed a right lower quadrant retroperitoneal dissection and cannulated the common iliac vein when systemic pressures deteriorated at 24 hours with marginal venous drainage. After triple cannulation the bypass flows were normal. The right leg developed mild cyanosis and edema immediately following cannulation, but these changes resolved over 24 hours with elevation. The common iliac vein provides a desirable route for augmentation of venous drainage in the patient with difficult standard, or cephalad, jugular venous access for extracorporeal support.

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.

Congenital diaphragmatic hernia (CDH) is a common cause of severe respiratory distress in the newborn. However, the presentation of CDH in older children and adults is rare, and, therefore, little is known concerning its symptoms, operative management, and postoperative complications. Thirteen patients (age range: 2 months to 26 years; 5 males, 8 females) presented with CDH. Four patients had right-sided hernias, eight left-sided hernias, and one bilateral hernias. Symptoms included chronic respiratory tract infections in 6 patients, vomiting in 5, weight loss in 1, severe failure to thrive in 2, and severe respiratory distress in 3; one patient was asymptomatic. Physical signs included the absence of breathing sounds or bowel sounds in the chest in eight patients, hyperresonance in one, and cachexia in two. The diagnosis was confirmed in each patient by chest roentgenogram or gastrointestinal contrast radiograph. All patients underwent immediate repair. After reduction of the viscera, 12 of 13 patients underwent primary diaphragm repair, whereas one patient required a prosthetic diaphragm patch. Twelve of 13 patients (92%) survived. Postoperatively, 7 of the 12 survivors (58%) developed severe gastric atony, and four required further operative therapy. In contrast to newborns, CDH in the older child and adult is frequently seen on the right side, rarely presents with severe respiratory distress, and is occasionally asymptomatic. Postoperative gastric atony is a major cause of morbidity, making transabdominal repair with simultaneous pyloroplasty and/or feeding jejunostomy the preferred operative approach.

This study examines whether patient outcomes are affected by changes in volume over time within hospitals and whether such effects are consistent with cross-sectional results previously reported in the literature. Investigating the existence of volume-outcome relationships longitudinally for specific groups of patients relates directly to the policy issue of whether, and how, specific inpatient services should be regionalized. The analysis uses up to 8 years of observations from a national sample of nearly 500 community hospitals. Outcomes are measured as inhospital mortality adjusted for case severity. Instrumental variables techniques are used to test and control for the possibility of selective referral. The results suggest that higher volume leads to better outcomes for certain groups of patients. Among the groups studied here, increases in volume lowered adjusted mortality rates for acute myocardial infarction, hernia repair, and respiratory distress syndrome in neonates; correlations were observed between volume and outcome for coronary artery bypass grafts, which seemed to be due primarily to referral patterns; and, no significant findings were found for hip replacements. In general, the effects of volume on outcome appear to be larger when estimated from longitudinal, rather than cross-sectional, data.

High-frequency jet ventilation (HFJV) is one of several high-frequency techniques that are particularly valuable for treating the neonate with lung disease refractory to conventional ventilation or with pulmonary air leak. Extracorporeal membrane oxygenation (ECMO) has also emerged as a valuable rescue therapy for neonates of more than 2000 g birth weight and 34 weeks' gestation with intractable respiratory failure. With the concurrent introduction of HFJV and ECMO, the authors sought to evaluate the role of HFJV prior to the institution of ECMO therapy. The data base for 2856 neonates receiving mechanical ventilation in one unit was used to identify 73 (of 298 total) neonates treated with HFJV, who were eligible by age and weight criteria for ECMO. Patients were grouped by diagnosis, and the oxygenation index (OI) was calculated during therapy. Outcome was evaluated for mortality, and the sensitivity of the OI for predicting mortality was calculated. Neonates who survived with HFJV alone presented with an OI of 0.30 +/- 0.03 (SEM), significantly less than nonsurvivors (0.42 +/- 0.04, P = .016). Survivors responded to HFJV with a rapid decrease in OI at 1 hour (0.19 +/- 0.02, P less than .001) and 6 hours (0.15 +/- 0.01, P less than .001). Nonsurvivors did not respond significantly at 1 hour (OI = 0.33 +/- 0.04, P = not significant [NS]) or at 6 hours (OI = 0.40 +/- 0.06, P = NS). By diagnosis, neonates with respiratory distress syndrome survived more often with HFJV (28/34, 82%) than neonates with meconium aspiration (10/26, 38%) or diaphragmatic hernia (3/9, 33%). Neonates with respiratory distress syndrome seldom presented with high OI values, but the majority of those who did survived (5/7 survived with initial OI greater than or equal to 0.40).(ABSTRACT TRUNCATED AT 250 WORDS)

Several new therapies have resulted in marked improvement in morbidity and mortality rates for neonates with respiratory distress syndrome and related disorders. These therapies include the use of exogenous surfactant to treat existing surfactant deficiency in babies with respiratory distress syndrome. Follow-up of patients previously treated with extracorporeal membrane oxygenation for diaphragmatic hernia has shown continued pulmonary function abnormalities despite this therapy. Follow-up studies have also shown significant neurologic abnormalities. New uses of ultrasonography include scanning of the larynx and airway for evaluating retropharyngeal and parapharyngeal infections and evaluating perithyroidal inflammation secondary to congenital fistulas in this region.
