Comparative Study
Initial evaluation of children sustaining blunt abdominal trauma: ultrasonography vs. diagnostic peritoneal lavage.
A prospective clinical study was performed to compare ultrasonography (US) with a modality having 96-99% accuracy like diagnostic peritoneal lavage (DPL) to find the accuracy of US in the initial evaluation of children sustaining blunt abdominal trauma (BAT). Sixty-eight children with BAT were initially evaluated by US, then DPL. All patients with pathologic US findings underwent computerized tomographic examination before DPL to confirm the pathologies. ⋯ The present study has shown that US can detect FIF with a high rate of accuracy comparable to DPL in children. In addition, US has advantages over DPL in the detection of intraperitoneal organ injuries with or without concomitant FIF, retroperitoneal injuries and intrathoracic injuries. Thus US is thought to be superior to DPL and recommended as a routine first choice screening tool in the initial evaluation of children sustaining BAT.

Nonoperative management of blunt liver injuries has become standard care for children, in the absence of hemodynamic instability. However, attention has to be drawn to biliary complications which can manifest themselves after a latent period, even in the presence of rupture of main biliary ducts. Peripheral bile duct lesions are easily treated by wide drainage. ⋯ Resection of the segment cured the patient. These two cases illustrate the occurrence of intrahepatic main bile duct lesions, clinically apparent after a latent period, following blunt trauma of the liver treated by nonsurgical or conservative surgical management. Intrahepatic biliary reconstruction is an alternative to liver resection when viable vascularization of the involved sector justifies its preservation.

Postoperative vomiting in children. A persisting unsolved problem.
Nausea and vomiting after anaesthesia and surgery in children remains a major problem. The following survey studies the frequency of postoperative vomiting and relates it to the anaesthetic technique, the surgical procedure, and postoperative analgesia. During one year, September 1989 until September 1990, 2370 surgical patients requiring anaesthesia were studied prospectively with the following protocol: 1) patient data, surgery and anaesthesia technique; and 2) postoperative follow-up were registered. ⋯ Furthermore, postoperative opioid administration on the ward increased the risk of vomiting. Despite the low overall incidence of vomiting in our study, we still found a high frequency after certain surgical procedures. The use of regional anaesthesia, prophylactic antiemetic medication, and the introduction of new anaesthetics, may help to reduce the sometimes high incidence of postoperative nausea and vomiting in paediatric patients.

Infants with congenital diaphragmatic hernia (CDH) die, because their lungs are hypoplastic and their pulmonary vascular resistance remains elevated after birth. In human newborns, it is difficult to appreciate the benefit of new therapeutic approaches, because the pathological findings are not uniform, the disease is rare and the clinical criteria for poor prognosis with conventional therapy are uncertain. To study the benefit of high-frequency ventilation (HFV) the use of Tolazoline in CDH, we created a diaphragmatic defect in sheep fetuses at 0.6 gestation and studied full-term newborns after a caesarian section. ⋯ Clinical and pathological findings of the lambs with CDH were very similar to severe CDH in humans with bilateral lung hypoplasia, severe respiratory distress, high pulmonary vascular resistance and severe hypoxemia. HFV dramatically improved CO2 elimination, allowed less aggressive ventilation, and was associated with higher flows and lower systemic and pulmonary vascular resistance. However, HFV did not improve oxygenation leaving the newborn with severe hypoxemia associated with massive intrapulmonary foramen ovale shunting from right to left.

Totally implantable central venous access devices in pediatric oncology--our experience in 46 patients.
Between 1986 and 1990, 50 venous access devices have been implanted in 45 children with various types of cancer and in one patient with Langerhans cell histiocytosis. Twenty-five devices were of the so-called "pediatric" type (Port-A-Cath: 24, Vascuport: 1) and 25 were "adult" ports (Port-A-Cath: 8, Vascuport: 6, Infuse-A-Port: 6, Theraport: 5). The catheters (in silicone elastomer or polyurethane) were inserted percutaneously or surgically. ⋯ Seven of the 11 complications, including all 3 port occlusions, were encountered with "pediatric" systems. All the adult access devices tested were safe and allowed long-standing access to the central venous system in this series of pediatric cancer patients. With proper placement technique and adequate nursing care, they represent a definite improvement in child cancer therapy.
