A primigravida allegedly allergic to local anaesthetics

Abstract:
Pregnant patients may give a history of allergy to local anaesthetics, but many of these supposed allergies have not been investigated. There is cross-reactivity between the amide local anaesthetics, which are the only group available in the UK for regional analgesia. We report the management of a primigravida who gave a history of allergy to two local anaesthetics, lidocaine and prilocaine. She was admitted to the labour ward at 38 weeks' gestation for challenge testing to the amide local anaesthetic bupivacaine, with full resuscitation and delivery facilities available. The tests proved negative and she was allowed home. She was re-admitted at term in labour and requested epidural analgesia. Epidural bupivacaine with fentanyl was used without incident for labour and forceps delivery. Subsequent allergy testing to lidocaine also proved negative.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
