Randomized Controlled TrialContinuous wound infusion with ropivacaine fails to provide adequate analgesia after caesarean section.
Continuous wound infusion with local anaesthetic has been used in post-caesarean pain management with conflicting results. We carried out a study comparing three groups: continuous ropivacaine wound infusion, intrathecal morphine with saline wound infusion and saline wound infusion only. ⋯ Compared to saline control, continuous wound infusion with ropivacaine failed to reduce the use of intravenous oxycodone patient-controlled analgesia or pain scores. Intrathecal morphine decreased oxycodone consumption by 46% in the first 24 h after surgery when compared to continuous ropivacaine wound infusion.

Tramadol produces analgesic effects through both non-opioid and weak opioid activity and is commonly used to treat mild to moderate pain. It has been in use for over 30 years and has a well-established safety profile in the general population. Since tramadol is not licensed for use in pregnancy and lactation, there is limited clinical research on its use in this patient population. A systematic review was undertaken of articles published in English before June 2011, searching Pubmed, Medline, CINAHL, Embase and Cochrane databases using the terms 'tramadol and pregnancy', 'tramadol and breastfeeding', 'tramadol and lactation', and 'tramadol and neonate'.

Case ReportsTransversus abdominis plane catheters for post-cesarean delivery analgesia: a series of five cases.
We present five cases of women who received ultrasound-guided transversus abdominis plane catheters for post-cesarean delivery analgesia. Pain relief was maintained with repeated boluses of local anesthetic combined with oral acetaminophen and ibuprofen unless contraindicated. We conclude that repeated dosing through transversus abdominis plane catheters may be offered to women as an alternative or adjuvant to intrathecal morphine. Larger studies to evaluate the safety and further refinements of this novel procedure are warranted.
