Sedation is frequently used during ophthalmic regional anaesthesia. There is no 'ideal' drug for sedation or analgesia. Various drugs either alone or in combination have been used with different methods of administration. This review includes the roles of sedation, the pharmacology of drugs and the safety of sedation in patients undergoing ophthalmic surgery.

Combined spinal-epidural analgesia is effective in labour analgesia. Nitric oxide may play important roles in pregnancy and labour and is probably affected by labour pain. The aim of the present study was to explore the alteration in serum levels of nitric oxide metabolites, i.e. nitrate and nitrite, during labour with or without combined spinal-epidural analgesia. ⋯ Combined spinal-epidural analgesia provided effective analgesia and abolished the decrease in nitric oxide metabolites during active labour.
