With over four million deliveries annually in the United States alone and a constant increase in cesarean delivery rate, childbirth is likely to have a huge impact on the occurrence of acute and possibly chronic postpartum pain. Recent awareness that chronic pain may occur after childbirth has prompted clinicians and researchers to investigate this topic. Current evidence points towards a relatively low incidence of chronic pain after cesarean delivery, with rates ranging between 1% and 18%. ⋯ Likely explanations are that the drugs that have been investigated were truly ineffective or that the effect was too modest because with a low incidence of chronic pain, studies were likely to be underpowered and failed to demonstrate an effect. In addition, since not all women require preventive therapies, preoperative testing that may identify women vulnerable to pain may be highly beneficial. Further research is needed to identify valid models that predict persistent pain to allow targeted interventions to women most likely to benefit from more tailored anti-hyperalgesic therapies.

Case ReportsRecurrent psychogenic paresis after dural puncture in a parturient.
We describe the case of a 29-year-old parturient who, after undergoing elective cesarean delivery, displayed symptoms of lower extremity weakness and sensory deficit. Her past medical history was significant for asymptomatic Arnold Chiari Type I malformation and asthma. She had received spinal anesthesia that failed to achieve an adequate surgical level requiring conversion to general anesthesia. ⋯ At 27 weeks of gestation, she had similar lower extremity symptoms after a lumbar puncture, performed to exclude meningitis for severe headache symptoms. Psychogenic paresis is not commonly reported in the medical literature and we found no reports of psychogenic paresis after spinal anesthesia in a parturient or recurrent psychogenic paresis. We review the various risk factors, etiology, neurological signs and symptoms, types, therapy and future management of a patient with recurrent conversion disorder.

Case ReportsEpidural injection of hydroxyethyl starch in the management of postdural puncture headache.
Epidural blood patch is the standard treatment for postdural puncture headache when symptomatic therapy is ineffective. We report the cases of two patients who received an epidural injection of hydroxyethyl starch when an epidural blood patch was contraindicated; one due to Streptococcus agalactiae bacteraemia and one due to acute leukaemia. Relief of headache was achieved in both patients with no adverse effects. The use of an epidural hydroxyethyl starch injection may be a suitable alternative for treatment of postdural puncture headache if epidural blood patch is contraindicated.

A qualitative analysis of parturients' perspectives on neuraxial labor analgesia.
The decision to use, or not use, neuraxial analgesia is complex and likely multi-factorial. The objectives of this study were to understand parturients' concerns about neuraxial analgesia, and the reasons for not anticipating the use of neuraxial analgesia using qualitative methodology. ⋯ Many women who anticipate not using neuraxial analgesia may be basing their decision on an inaccurate understanding of the risks of the procedure. Improved patient education and counseling that target specific areas of concern may address these misunderstandings.
