A 36-year-old, 204-kg parturient with a past medical history of Factor V Leiden requiring enoxaparin therapy developed a postdural puncture headache. With careful coordination of her enoxaparin dosing, an epidural blood patch was successfully performed. Performance of a blood patch in patients taking enoxaparin involves the withholding of the medication for a specific period.

Randomized Controlled Trial Clinical Trial
Does sealing endotracheal tube cuff pressure diminish the frequency of postoperative laryngotracheal complaints after nitrous oxide anesthesia?
To study endotracheal tube (ETT) cuff pressures during nitrous oxide (N2O) anesthesia when the cuffs are inflated with air to achieve sealing pressure, and to evaluate the frequency of postoperative laryngotracheal complaints. ⋯ Minimum ETT sealing cuff pressure during N2O anesthesia did not prevent, but instead attenuated, the increase in cuff pressure and did not decrease postoperative laryngotracheal complaints.

To evaluate the correlation between accepted screening tests for difficult tracheal intubation and ease of intubation with a lightwand blind technique. ⋯ Mallampati class III airway significantly increases time to intubation when the transillumination technique is used. BMI > or = 30 kg/m2 is another factor that interferes with the ease and success of intubation with this technique.

Spontaneous spinal epidural hematoma is a rare occurrence during pregnancy with only five cases described in the literature since 1900. Even in the general population, the frequency of spontaneous spinal epidural hematoma is extremely low and the etiology unclear. Several theories exist for the cause of spontaneous spinal epidural hematoma, however, none has gained uniform acceptance. ⋯ We hypothesize that the cause of spontaneous spinal epidural hematoma is multifactorial, and pregnancy-induced structural changes in arterial walls and hemodynamic changes may play a role. In addition, we postulate that the origin of the bleeding is arterial, rather then venous. Lastly, the symptoms, diagnosis, and management of spontaneous spinal epidural hematoma during pregnancy are discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Cardiovascular changes after extraglottic airway insertion: a prospective, randomized comparison between the laryngeal mask or the new PAXpress.
To compare hemodynamic responses induced with the new extraglottic airway, PAXpress, and the classic Laryngeal Mask Airway (LMA). ⋯ Although further studies are required to evaluate safety and airway trauma of this new extraglottic airway, placing the PAXpress produces more marked changes in hemodynamic variables as compared with those produced by the LMA.
