Amnioinfusion aims to prevent or relieve umbilical cord compression during labour by infusing a solution into the uterine cavity.. To assess the effects of amnioinfusion for potential or suspected umbilical cord compression on maternal and perinatal outcome .. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2011).. Randomised trials of amnioinfusion compared with no amnioinfusion in women with babies at risk of umbilical cord compression in labour.. The original review had one author only (Justus Hofmeyr (GJH)). For this update, two authors (GJH and T Lawrie) assessed 13 additional trial reports for eligibility and quality. We extracted data and checked for accuracy.. We have included 19 studies, with all but two studies having fewer than 200 participants. Transcervical amnioinfusion for potential or suspected umbilical cord compression was associated with the following reductions: caesarean section overall (13 trials, 1493 participants; average risk ratio (RR) 0.62, 95% confidence interval (CI) 0.46 to 0.83); fetal heart rate (FHR) decelerations (seven trials, 1006 participants; average RR 0.53, 95% CI 0.38 to 0.74); Apgar score less than seven at five minutes (12 trials, 1804 participants; average RR 0.47, 95% CI 0.30 to 0.72); meconium below the vocal cords (three trials, 674 participants, RR 0.53, 95% CI 0.31 to 0.92); postpartum endometritis (six trials, 767 participants; RR 0.45, 95% CI 0.25 to 0.81) and maternal hospital stay greater than three days (four trials, 1051 participants; average RR 0.45, 95% CI 0.25 to 0.78). Transabdominal amnioinfusion showed similar trends, though numbers studied were small.Mean cord umbilical artery pH was higher in the amnioinfusion group (seven trials, 855 participants; average mean difference 0.03, 95% CI 0.00 to 0.06) and there was a trend toward fewer neonates with a low cord arterial pH (less than 7.2 or as defined by trial authors) in the amnioinfusion group (eight trials, 972 participants, average RR 0.58, 95% CI 0.29 to 1.14).. The use of amnioinfusion for potential or suspected umbilical cord compression may be of considerable benefit to mother and baby by reducing the occurrence of variable FHR decelerations, improving short-term measures of neonatal outcome, reducing maternal postpartum endometritis and lowering the use of caesarean section, although there were methodological limitations to the trials reviewed here. In addition, the trials are too small to address the possibility of rare but serious maternal adverse effects of amnioinfusion. More research is needed to confirm the findings, assess longer-term measures of fetal outcome, and to assess the impact on caesarean section rates when the diagnosis of fetal distress is more stringent. Trials should assess amnioinfusion in specific clinical situations, such as FHR decelerations, oligohydramnios or prelabour rupture of membranes.

Intestinal obstruction in the newborn infant may be due to a variety of conditions, including atresia and stenosis, annular pancreas, malrotation, duplication cyst, meconium ileus, meconium plug syndrome and neonatal small left colon syndrome, and Hirschsprung's disease. Neonates with unrecognised intestinal obstruction deteriorate rapidly, show an increase of associated morbidity and appropriate surgical treatment becomes more hazardous. Early diagnosis depends largely on the prompt detection of obstructive manifestations by the clinician and the subsequent accurate interpretation of radiographic findings by the radiologist. Plain film of the abdomen is often helpful in determining the level of obstruction and usually dictates, together with clinical symptoms, the choice of the contrast study firstly to perform. In this article we will review the clinical and radiological signs of different pathological conditions causing intestinal obstruction in the newborn.

Anorectal atresia and rectal stenosis are rare types of anorectal malformations, accounting for only 1-2% of cases. We here report one case of anorectal atresia. The study involved a female newborn baby delivered at term via vaginal birth, weighing 3600g, who was admitted with failure to pass meconium, abdominal bloating and fever on day 6 of life. Clinical examination showed a temperature of 39

We have observed five children with cystic fibrosis, who presented over 2 months, with meconium ileus equivalent that failed to respond to medical management. At surgery, four had a stricture in the ascending colon, and all had histopathological changes of post-ischaemic ulceration repair, with mucosal and submucosal fibrosis. The only common change in the management of these children was a switch from conventional enteric-coated pancreatic enzymes to high-strength products 12-15 months before presentation.

In a review of cases of intestinal atresia or stenosis in the newborn at Children's Hospital of Los Angeles it was noted that in approximately 10 per cent there was clinical or anatomic evidence of fibrocystic disease of the pancreas. Histologic sections of the bowel in all these cases showed the alterations of the mucosa commonly found in fibrocystic disease. Extensive ulceration, foreign body reaction and calcium deposition in the bowel wall were observed in five cases. Sections through the site of obstruction in one patient showed narrowing of the diameter of the bowel with preservation of muscular layers, but replacement of the central portion by a vascular, fibrous diaphragm in which giant cells, hemosiderin and calcium were prominent. This suggested that in certain instances obstruction of the intestine may be caused by fibrosis secondary to injury of the mucosa by abnormal meconium. Awareness of the common association of intestinal obstruction and fibrocystic disease of the pancreas and recognition of the histologic change in the bowel in fibrocystic disease may lead to early diagnosis of this disorder in some infants with intestinal obstruction.
