Intracranial haemorrhage (ICH) is a devastating cause of stroke. Although the total incidence of ICH has remained stable worldwide, the proportion associated with the use of anticoagulant medications is increasing. Innovative interventions developed to improve patient outcomes often require peri-procedure anaesthetic management. This non-systematic review examines the pathophysiology of ICH at a clinical level, reports on novel therapeutic interventions, many of which are currently in clinical trials, and reviews the current published recommendations for the management of patients with ICH.

Recent advances in imaging have improved our understanding of the role of the brain in painful conditions. Discoveries of morphological changes have been made in patients with chronic pain, with little known about the functional consequences when they occur in areas associated with 'number-sense'; thus, it can be hypothesized that chronic pain impairs this sense. ⋯ Audit data suggest patients with chronic pain interpret numbers differently from acute pain sufferers. Support is gained by experiments indicating impaired number sense in one-third of chronic pain patients. These results cast doubts on the appropriateness of the use of visual analogue and numeric rating scales in chronic pain in clinics and research.

Clonidine is a useful analgesic-sedative agent; however, few data exist regarding its use in infants after congenital heart disease surgery. We thus aimed to assess the absorption and safety of enterally administered clonidine in this setting. ⋯ Early postoperative enteral clonidine produces favourable haemodynamic profiles and therapeutic plasma concentrations in the majority of cardiac surgical infants; however, the time to achieve this can be erratic. Thus, parenteral administration may be preferable if rapid analgo-sedative effects are needed.
