Observational StudyThe use of cell salvage in women undergoing cesarean hysterectomy for abnormal placentation.
Although transfusion of autologous blood obtained from cell salvage has increased, its role in obstetric practice remains controversial. This case series reports the use of cell salvage in an attempt to avoid allogeneic transfusion in women undergoing cesarean hysterectomy for placenta accreta. ⋯ Autologous transfusion of salvaged blood can be used to minimize allogeneic transfusion in women undergoing cesarean hysterectomy for placenta accreta.

Case ReportsAirway obstruction, caesarean section and thyroidectomy.
Airway obstruction in pregnancy is rare. We report the case of a 39-year-old nulliparous woman with a body mass index of 47 kg/m(2) and a large multinodular goitre causing tracheal compression with airway symptoms who declined thyroid surgery until after delivery. However, worsening hypertension precipitated an urgent caesarean section and thyroidectomy at 32 weeks of gestation. ⋯ Caesarean section was performed and a healthy baby delivered followed by a total thyroidectomy. She was extubated, monitored closely for tracheomalacia and cared for postoperatively in the surgical high-dependency unit. This case highlighted a number of challenges managed successfully with a multidisciplinary team.

The influence of timing on the effectiveness of epidural blood patches in parturients.
Postdural puncture headache is common in parturients following lumbar puncture. If headache is severe and persistent, an epidural blood patch is recommended. In this paper we reviewed the efficacy of epidural blood patches over a 13-year period at two hospitals in Finland with a particular emphasis on its timing. ⋯ Epidural blood patch performed later than 48 h following lumbar puncture or accidental dural puncture is effective in parturients with postdural puncture symptoms. The recurrence rate of symptoms after an initially successful epidural blood patch is high, and therefore patients should be provided with counselling and contact information.

Assessing blocks after spinal anaesthesia for elective caesarean section: how different questions affect findings from the same stimulus.
A block to touch to T5 is widely used to indicate an adequate level of block for caesarean section with spinal anaesthesia. However, two studies using a "block to light touch" to T5 as their end-point, had a high requirement for intraoperative analgesia and their results cast doubt on the adequacy of a block to touch to T5. On enquiry, these two papers did not assess complete block to touch, but asked mothers when the touch sensation "was the same as" a control stimulus. The difference between these two assessment methods is unknown. The current study presents prospectively collected sensory block data which included both block to touch and the level when touch was the same as a control stimulus. ⋯ When describing a sensory block, not only is it necessary to indicate the exact stimulus used, but it is important to define the actual question asked of the patient. Clinically, block assessment using the first sharp level and touch same as control are equivalent.
