Neurophysiological assessment of acute pain in infants: a scoping review of research methods.

A systematic scoping search to describe the neurophysiological methods used in infant acute pain assessment research was conducted. Of the 2411 abstracts screened, 19 articles were retained. Nine studies utilised near-infrared spectroscopy (NIRS), two utilised functional magnetic resonance imaging (fMRI), and eight utilised electroencephalography (EEG). There was methodological variability in studies utilising NIRS, whereas EEG and fMRI studies reported consistent methods. Of the eight EEG studies, six identified a nociceptive-specific event-related potential. CONCLUSION: While more methodologically rigorous studies are needed, ERPs appear to hold some promise as indicators of infant nociception during clinical procedures to supplement existing measures.

Assessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.

OBJECTIVE: Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain. The aim of the study was to determine whether in fetuses with spina bifida this displacement of the brain is evident from the first trimester of pregnancy. METHODS: In women undergoing routine ultrasound examination at 11-13 weeks' gestation as part of screening for chromosomal abnormalities, a mid-sagittal view of the fetal face was obtained to measure nuchal translucency thickness and assess the nasal bone. In this view the fourth ventricle, which presents as an intracranial translucency (IT) between the brain stem and choroid plexus, is easily visible. We measured the anteroposterior diameter of the fourth ventricle in 200 normal fetuses and in four fetuses with spina bifida. RESULTS: In the normal fetuses the fourth ventricle was always visible and the median anteroposterior diameter increased from 1.5 mm at a crown-rump length (CRL) of 45 mm to 2.5 mm at a CRL of 84 mm. In the four fetuses with spina bifida the ventricle was compressed by the caudally displaced hindbrain and no IT could be seen. CONCLUSION: The mid-sagittal view of the face as routinely used in screening for chromosomal defects can also be used for early detection of open spina bifida.

[Complete cost of surgery for postpartum haemorrhage]. / Coût total des actes chirurgicaux dans la prise en charge des hémorragies de la délivrance.

OBJECTIVE: Reduction of maternal mortality is a major priority in the public health domain. One of the main causes of maternal mortality is postpartum haemorrhage. Because economic pressures favour the use of less expensive strategies, it is becoming now critical to know exactly the cost of the surgical procedures involved in the treatment of postpartum haemorrhage, in order to provide future guidelines in Implementing reforms in hospital. MATERIALS AND METHODS: Evaluation was made on multiple data collected in the Gynecology-Obstetrics and Central Sterile Supplies departments of a tertiary care Hospital. Analysis of the production costs was made based on the actual costs. The receipts were figured on the basis of applicable reimbursement in France in 2005, taking into account the financial decisions of the producers. RESULTS: From January 2004 to December 2005, 262 patients were treated for postpartum hemorrhage and patients files were available for review in 255 cases. Of these, surgery was performed in 52 cases. The costs of surgery in the postpartum care ranged from 275.04 euro per manual exploration of the uterine cavity (n=8), 302.48 euro per exploration with valve (n=26), 601.55 euro per vascular ligation (n=3), 725.53 euro per vaginal packing or unpacking (n=10) to 875.06 euro per hysterectomy (n=5). Cleaning and sterilizing of surgical instruments represented a substantial burden, ranging from 7.5% to 11.4% of the total cost of surgery. DISCUSSION AND CONCLUSION: The costs of surgery for postpartum haemorrhage have been calculated to provide future guidelines for the directions and follow-up of these activities in light of the T2A-EPRD and poles of activity. The actual costs could be used to determine the bases of one or more French DRGs (PMSI) "postpartum hemorrhage" evolution.
