What is new in postoperative analgesia after caesarean sections?

Role of Opioids: Historically opioids are most commonly administered analgesia for postoperative CS pain management. They are used both systemically and neuraxially for postoperative analgesia. Systemic administration is mostly used after general anaesthesia and in places where there is unavailability of long acting preservative free opioids or lack of expertise in its usage. Systemic routes for opioids administration are intramuscular and intravenous, given either intermittently, on demand basis or by intravenous continuous method.
