Anaesthesia for Caesarean section: Regional anaesthesia
Regional anaesthesia is the technique of choice for CS, provided no contra-indications exist. The relationship between increased use of regional techniques and decreased maternal mortality is well recognized, with evidence suggesting it to be 16 times safer than GA. The use of three commonly practised techniques; epidural top-up, spinal, and combined spinal–epidural anaesthesia are described in detail in this chapter. Pain during CS surgery is the most common complaint and litigation made against obstetric anaesthetists. The importance and conduct of thorough block assessment prior to commencement of surgery and its documentation is emphasized with a ‘top tips’ list. Management of a failed block is described for all three techniques, together with strategies to treat common intra-operative complications e.g. hypotension and respiratory difficulty.
