Knowledge, attitude and practice on usage and toxicity of local anaesthetic agents (LA) amongst health care professionals in obstetrics and gynaecology.

A sound knowledge of LA and their dosage is essential for effective anaesthesia and patient safety as LA toxicity could be potentially life-threatening and clinicians undertaking LA procedures must be competent in early recognition of toxicity and instigating remedial measures timely. This is a prospective national-level survey using self-administered questionnaires among health care professionals in Obstetrics and Gynaecology primarily based in Worcestershire Acute Hospital NHS Trust and further extended to other regions of the United Kingdom. The survey was focussed on evaluating the knowledge, attitude and practice (KAP) of the common local anaesthetic agents, their dosage, early recognition and management of LA systemic toxicity(LAST).
