[Protective efficacy of 3 anesthetic methods with reference to surgical stress in children].

Hormonal-metabolic stress responses have beyond doubt an effect on morbidity/mortality related to surgery. The present study med to determine which anaesthetic technique could afford the best protection in children, through analysis of the perioperative cortisol, prolactin and beta-endorphin plasma levels. Thirty-six young patients 3-10 years old, ASA I-II, scheduled for hypospadias or vesicoureteral reflux surgery of a duration > 60 min, were randomized into three groups (n = 12). Children of group I were given initially propofol and fentanyl then isoflurane 1%; group 2 received TIVA with propofol and fentanyl, group 3 received initially propofol then an epidural lumbar block with bupivacaine 0.25% (single shot) and continuous propofol i.v. infusion. Cortisol, prolactin and beta-endorphin levels increased significantly in group 1 only. No significant differences were observed between group 2 and 3. Early postoperative analgesia was better in group 3. These data suggest that TIVA and particularly epidural block could afford a better protection against the surgical stress in children submitted to subumbilical operations.

Long-gap oesophageal atresia: a combined endoscopic and radiologic evaluation.

The final aim of the treatment of oesophageal atresia is to restore continuity without the interposition of intestinal segments. The authors present the results of a new diagnostic method combining endoscopy and radiology to evaluate the development of pouches in oesophageal atresia. This new method has been successfully adopted in four patients aged between 4 and 8 months, three with type I and one with type III complicated atresia. Direct end-to-end anastomosis was performed in all patients. We think this method can be easily applied and is a suitable diagnostic examination in all cases in which surgical strategy aims at restoring oesophageal continuity by means of direct anastomosis.

[Necrotizing enterocolitis].

Necrotizing enterocolitis (NEC) is an important cause of neonatal morbidity and mortality. During the last few years, there was an increase in the incidence of this disease, associated with a better knowledge of NEC, and an increase in survival rate, associated with the development, even from a technological point of view, of neonatal intensive care units. In this study, the authors first perform the diagnostic procedures and describe the anatomical and clinical characteristics of NEC, then evaluate by standard criteria a series of patients observed during the last 5 years, revising the various surgical treatments adopted and the results obtained.

[Unusual pelvic pathology treated with posterior sagittal anorectoplasty].

Posterior sagittal approach is very useful for the correction of anorectal malformations, but it can be used also for the treatment of pelvic or perineal masses. The authors present 3 patients affected one by a perineal hamartoma, one by a rectal duplication and one by a retrorectal cystic teratoma. All the patients were treated following the PSARP technique, using the Penã's bipolar electro-stimulator just in order to respect all the muscles of the anorectal sphincters. Using this procedure the authors were able to preserve the full anorectal continence in all the 3 patients.

[Advantages of a permanent venous access in children treated for cancer. Preliminary results].

Current therapy for children with cancer includes a variety of invasive procedures many of which require repeated venous access over a considerable period of time. Such procedures are poorly tolerated by children and by their veins. Recently it has become possible to undertake the majority of such procedures by means of permanent indwelling silastic catheters improving the quality of life of the children and their parents and increasing the scope of therapeutic intervention. In the period July '83 - August '84 we have used 46 of these catheters in 45 children with malignant disease, 12 with acute myeloid leukaemia, 12 with neuroblastoma, 7 with B cell leukaemia-lymphoma, 6 with rhabdomyosarcomas, 2 with Ewing's Sarcoma, 2 with Wilms' tumor and 1 case each of Hodgkin's disease, teratocarcinoma, osteosarcoma and juvenile chronic myeloid leukaemia. The children's ages ranged from 2 months to 14 years; 22 were male and 23 female. The catheters were inserted under general anaesthesia (duration 20-40 minutes) usually without difficulty, except for a single patient in whom no suitable vein could be found. No complications connected with the placement of the catheter were observed. Subsequent management of the catheter was initially complicated and time-consuming, but was subsequently simplified so that acceptance by parents, children and nursing staff was eventually excellent. The duration of use of 46 catheters ranges from 7 to 350+ days; 24 catheters are presently in use at 30-350+ days from insertion. Eight children died as a result of disease progression and two of sepsis with the catheter in place.(ABSTRACT TRUNCATED AT 250 WORDS)
