Traumatic brain injury remains a worldwide problem. Newer modalities in the management of such injuries include both drugs and therapeutic strategies. Continuing research in animal models has provided a better understanding of the pathophysiological processes that follow head injury, and this in turn has enabled workers to work on improved treatment targets. Although there are exciting and novel approaches emerging, there is no substitute for meticulous initial resuscitation. Additionally, some of the more well known management options are now better understood. These concepts are discussed in the article.

Subarachnoid haemorrhage due to rupture of cerebral aneurysms is a multisystem disease. Treatment of the condition in the past has relied on craniotomy and clipping of the aneurysm to prevent a recurrent haemorrhage. There is now emerging evidence to suggest that endovascular treatment of cerebral aneurysms may reduce the morbidity associated with open surgery. The anaesthetic management of interventional neuroradiology also creates new challenges due to the novel approach to treatment. Anaesthetists need to be familiar with this procedure and the management of potential complications. This review provides an overview such considerations.

The Montgomery T-tube is a device used as a combined tracheal stent and an airway after laryngotracheal surgery. The device is used mostly in specialist centres for head and neck surgery, and therefore, many anaesthetists may be unfamiliar with its use. The Montgomery T-tube presents the anaesthetist with challenges both during its surgical insertion when acute loss of the airway might occur and also during induction of anaesthesia in patients who have such a tube in situ. Anaesthetists who are unfamiliar with the tube may have to resort to ingenious ways of coping with the problems of a shared airway with a T-tube, which does not have a suitable adaptor for a standard catheter mount, as well as controlling and maintaining ventilation through the device. Safe management of such patients requires careful planning. We describe the anaesthetic management of two cases to illustrate the problems associated with Montgomery tubes.

A simple way of evaluating surgical outcomes is to compare mortality and morbidity. Such comparisons may be misleading without a proper case mix. The POSSUM scoring system was developed to overcome this problem. The score can be used to derive predictive mortality and morbidity for surgical procedures. POSSUM and a modified version P-POSSUM have been evaluated in various groups of surgical patients for the accuracy of predicting mortality. These scoring systems have not been evaluated in neurosurgical patients. Thus, we tried to evaluate the usefulness of POSSUM and P-POSSUM scoring systems in neurosurgical patients in predicting in-hospital mortality. POSSUM physiological and operative variables were collected from all neurosurgical patients undergoing elective craniotomy, from April 2005 to Feb 2006. In-hospital mortality was obtained from the hospital mortality register. The physiological score, operative score, POSSUM predicted mortality rate and P-POSSUM predicted mortality rate were calculated using a calculator. The observed number of deaths was compared against the predicted deaths. A total of 285 patients with a mean age of 38 +/- 15 years were studied. Overall observed mortality was nine patients (3.16%). The mortality predicted by the P-POSSUM model was also nine patients (3.16%). Mortality predicted by POSSUM was poor with predicted deaths in 31 patients (11%). The difference between observed and predicted deaths at different risk levels was not significant with P-POSSUM (p = 0.424) and was significantly different with POSSUM score (p < 0.001). P-POSSUM scoring system was highly accurate in predicting the overall mortality in neurosurgical patients. In contrast, POSSUM score was not useful for prediction of mortality.

Team resource management skills learnt in a single educational intervention, based on simulated anaesthetic emergencies, are retained over the long term, translated into clinical practice and are transferable across the breadth of clinical activities.
