OBJECTIVE: Assisted delivery is necessary in many obstetrical conditions but is involved in maternal and foetal complications. The legal pressure and the commendable aim consisting in less neonatal morbidity and mortality have called forth a reflection about the type and the way of instrumental foetal extraction. In 1950, Thierry had already felt this problem and he invented spatula to replace obstetrical forceps. Although this instrument appears empirically little deleterious, literature about its evaluation is very poor. We studied this instrument in a retrospective 190 cases series. PATIENTS AND METHOD: Retrospective study of 190 Thierry's spatula extractions, over a seven-year period (January 1996 to December 2002), at the Centre Hospitalier General of Montbeliard. RESULTS: Out of a total of 8126 deliveries for the study period, the instrumental extraction rate was 5.3%, with 40.6% spatula extractions (190 cases). No failure of Thierry's spatula extraction was noted. DISCUSSION ET CONCLUSION: Our study concludes that spatula is efficient but does not usually permit anterior rotation of occipito-posterior presentation. Maternal and foetal morbidity is not frequent.
Brainstem damage which often indicates a critical condition is usually underestimated by trans-anterior-fontanel neurosonography (NS) owing to the far-field limitations. Instead, NS alternately scanning through the squamous suture of the temporal bones and the foramen magnum could provide a better visualization of the brainstem structures. The NS characteristics of brainstem lesions caused by various neonatal neurological disorders, such as hypoxic-ischemic encephalopathy (HIE), metabolic encephalopathy, birth trauma and bacterial meningoencephalitis, can be depicted at the acute stage. An echogenic change in the midbrain was found in patients with HIE or metabolic encephalopathy. In addition to the echogenic change, bilateral transtentorial temporal lobe herniation distorting the contour of the midbrain was observed in a patient with group B streptococcus meningoencephalitis, whereas echogenic changes at the level of the pons and/or the medulla oblongata, mainly localized in the dorsal part, could be observed in newborns with severe HIE, maple syrup urine disease or birth trauma. In this pictorial assay, we demonstrate the feasibility of NS imaging in evaluating the entire brainstem structure of critically ill neonates in the near field and illustrate the characteristic features of brainstem involvement in various neonatal neurological disorders along with computed tomography or magnetic resonance imaging correlation.
