RESUMEN

The obstetrical follow-up of patients with a severe hypofibrinogenemia requires a multidisciplinary collaboration because of potential maternal-fetal complications (recurrent miscarriages, intrauterine fetal demise, post-partum hemorrhage, thrombosis). We report the obstetrical management of a multiparous patient with a severe congenital hypofibrinogenemia associated with a platelet disorder (abnormal phospholipid externalization). A therapeutic strategy based on a biweekly administration of fibrinogen concentrates associated with enoxaparin and aspirin allowed the maintenance of pregnancy. But this last one got complicated by a placenta percreta requiring a salvage hysterectomy with an appropriate hemorrhage prophylaxis.

RESUMEN

Background: Impairment of pulmonary aeration is a frequent postoperative complication that is associated with adverse outcome. Diagnosis and quantification of impaired pulmonary aeration by CT scan is limited due to concern for exposure to ionizing radiation. Magnetic resonance imaging (MRI) represents a potential radiation-free alternative for this use. We undertook an experimental study to validate the use of MRI to quantify pulmonary aeration impairment. Methods: Ten large white pigs were studied before intubation, after intubation, 2 h after non-protective mechanical ventilation and after intra-tracheal negative pressure suction to induce atelectasis. A lung CT scan immediately followed by a lung MRI were performed at all four time points. On the 40 CT images lung volumes corresponding to non-aerated, poorly aerated, normally aerated, and overinflated voxels were measured based on their radiodensity. Similarly, on the 40 MRI images lung volumes corresponding to non-aerated and aerated voxels were measured based on their signal intensity. The correlation between non-aerated lung by MRI vs., CT scans, and with PaO2/FiO2 measured at each of the four time points was assessed with the Pearson' correlation coefficient, bias and limits of agreement. Results: Pearson correlation coefficient, bias and limits of agreements between the CT non-aerated lung volumes and MRI abnormal lung volumes were 0.88, -16 ml, and (-108, 77), respectively. Pearson correlation coefficient between PaO2/FiO2 and abnormal lung volumes measured with MRI was -0.60. Conclusion: In a preclinical swine model, quantitative measurements of pulmonary atelectasis by MRI-imaging are well correlated with the gold standard, i.e., densitometric scan CT measurements.

RESUMEN

Transnasal humidified rapid-insufflation ventilatory exchange has been shown to improve oxygenation and increase apnea time in difficult airway cases. It may also be beneficial in patients vulnerable to rapid desaturation due to limited pulmonary reserve. We report the use of transnasal humidified rapid-insufflation ventilatory exchange for preoxygenation before a cesarean delivery under general anesthesia in a patient with respiratory distress because of pneumonia and heart failure from severe mitral stenosis. To our knowledge, the use of this technique has not been previously reported in pregnant patients.
