Safe Use of Epidural Analgesia in a Parturient With Spinocerebellar Ataxia: A Case Report.

A 28-year-old, gravida 7, para 4 woman with medical history of sickle cell trait presented to labor and delivery at 39 weeks of gestation for rupture of membranes. The patient had a history of suspected spinocerebellar ataxia with incomplete workup before the current admission. The patient requested epidural analgesia for labor. Epidural was placed at L3-L4 interspace without any complications and the rest of the labor was uneventful. Magnetic resonance imaging of the brain was performed after the delivery and the diagnosis of spinocerebellar ataxia was confirmed. The patient's neurological status remained stable after the procedure.

Modified Tricuspid Annular Plane Systolic Excursion Using Transesophageal Echocardiography and Its Utility to Predict Postoperative Course in Heart Transplantation and Left Ventricular Assist Device Implantation.

OBJECTIVES: Perioperative right ventricular (RV) function is important for determining the postoperative course in heart transplantation (HT) and left ventricular assist device (LVAD) implantation. The authors describe a modified tricuspid annular plane systolic excursion (m-TAPSE) using transesophageal echocardiography and assessed its clinical utility in HT and LVAD. DESIGN: Retrospective medical record review. SETTING: A single tertiary-care medical center. PARTICIPANTS: Forty-eight patients who underwent successful HT and 80 patients who underwent successful LVAD placement. MEASUREMENTS AND MAIN RESULTS: Statistically significant correlation between m-TAPSE and RV fractional area change (FAC) was seen for HT and LVAD (r = 0.462, p < 0.01 and r = 0.597, p < 0.01, respectively). For HT, receiver operating characteristics curve analysis yielded that m-TAPSE <0.64 cm provides 100% specificity and 57.1% sensitivity in predicting postoperative nitric oxide (NO) use, whereas RV FAC <24.1% provides 95.1% specificity and 71.4% sensitivity in predicting postoperative NO use (area under the curve 0.798 [95% confidence interval (CI), 0.595-1] v 0.826 [95% CI, 0.581-1], p = 0.397). For LVAD, m-TAPSE <0.71 cm provides 66.7% specificity and 87.5% sensitivity in predicting postoperative NO use, whereas RV FAC <16.3% provides 79.4% specificity and 62.5% sensitivity in predicting postoperative NO use (area under the curve 0.829 [95% CI, 0.732-0.927] v 0.691 [95% CI, 0.54-0.842], p < 0.05). CONCLUSIONS: m-TAPSE validated a good correlation to RV systolic function as reflected by RV FAC for both HT and LVAD. For HT, m-TAPSE was helpful for predicting postoperative NO use; whereas for LVAD, m-TAPSE was helpful for predicting postoperative NO use and RV assist device implantation. m-TAPSE should be considered as a useful parameter to decide postoperative management for these cases.
