ABSTRACT
BACKGROUND: Myelomeningocele (MMC) is a neural tube defect disease. Antenatal repair of fetal MMC is an alternative to postnatal repair. Many agents can be used as tocolytics during the in utero fetal repair such as ß2-agonists and oxytocin receptor antagonists, with possible maternal and fetal repercussions. This study aims to compare maternal arterial blood gas analysis between terbutaline or atosiban, as tocolytic agents, during intrauterine MMC repair. METHODS: Retrospective cohort study. Patients were divided into two groups depending on the main tocolytic agent used during intrauterine MMC repair: atosiban (16) or terbutaline (9). Maternal arterial blood gas samples were analyzed on three moments: post induction (baseline, before the start of tocolysis), before extubation, and two hours after the end of the surgery. RESULTS: Twenty-five patients were included and assessed. Before extubation, the terbutaline group showed lower arterial pH (7.347 ± 0.05 vs. 7.396 ± 0.02 for atosiban, p = 0.006) and higher arterial lactate (28.33 ± 12.76 mg.dL-1 vs. 13.06 ± 6.35 mg.dL-1, for atosiban, p = 0.001) levels. CONCLUSIONS: Patients who received terbutaline had more acidosis and higher levels of lactate, compared to those who received atosiban, during intrauterine fetal MMC repair.

Context: Chronic subdural hematomas are frequent diseases in neurosurgery units. Decreased level of consciousness is observed in 28 to 100 percent of cases, nevertheless in rare cases are seen comatous patients. We describe a case of a patient with clinical uncal herniation elapsed by a chronic subdural hematoma. Case report: Patient with previous diagnosis of breast cancer, presented sudden occurrence of a headache followed by decreasing level of consiousness the day before reaching our service. The patient was taken than to another Hospital at 1:00 AM in Glasgow Coma Scale (GCS) 13, with isochonic pupils. At 7:00 AM the GCS went to 7 and the pupils became anisochonic L > R and than transferred to our Unit and immediatly submitted to a computed tomohraphy scanning of the head that showed a chronic subdural hematoma with midline shift. The patient promptly was taken to surgical room and treated with a single burr hole with drainage of hypertensive chronic subdural hematoma. The level of consiousness increased few hours after surgery, being in GCS 15 just 6 hours after, without motor deficits. Conclusion: In spite of commonly progressive evolution chronic subdural hematomas can present with herniation, becoming itself a neurosurgical emergency.
