ReviewProvision for major obstetric haemorrhage: an Australian and New Zealand survey and review.
Obstetric haemorrhage is a leading cause of maternal death and the most common contributor to serious obstetric morbidity. Maternal mortality audit data suggest that appropriate preparation and good emergency management leads to improved outcome. The aim of this study was to assess facilities relevant to major obstetric haemorrhage management in all units in Australia and New Zealand that offer operative obstetric services. ⋯ Haemorrhage responds well to appropriate treatment, although careful preparation and anticipation of problems is required. In our region geographical factors and different systems of healthcare complicate provision of obstetric services. Where facilities are limited, women should be offered antenatal transfer to a larger centre.

ReviewOutcome-based clinical indicators for intensive care medicine.
The clinical indicator is a tool used to monitor the quality of health care. Its use in the Intensive Care Unit (ICU) is desirable for many reasons: the maintenance of minimum standards, the development of best practice and the delivery of cost-effective health care. ⋯ Monitoring of adverse events, system descriptors, and resource indicators is valuable but they have a limited relationship to the quality of care. ICU mortality prediction models provide a global measure of quality and, despite their inherent deficiencies, remain one of the most robust and useful clinical indicators.

ReviewAnaesthesia for neurosurgery in the sitting position: a practical approach.
Neurosurgery in the sitting position offers advantages for certain operations. However, the approach is associated with potential complications, in particular venous air embolism. As the venous pressure at wound level is usually negative, air can be entrained. ⋯ Other particular concerns to the anaesthetist are airway management, avoidance of pressure injuries, and the risk of pneumocephalus, oral trauma, and quadriplegia. Newer anaesthetic agents have made the choice of anaesthetic technique easier. An appreciation of the implications of neurosurgery in the sitting position can make the procedure safer

ReviewAcute pain management pharmacology for the patient with concurrent renal or hepatic disease.
The clinical utility of most analgesic drugs is altered in the presence of patients with impaired renal or hepatic function not simply because of altered clearance of the parent drug, but also through production and accumulation of toxic or therapeutically active metabolites. Some analgesic agents may also aggravate pre-existing renal and hepatic disease. A search was performed, taking in published articles and pharmaceutical data to determine available evidence for managing acute pain effectively and safely in these two patient groups. ⋯ The agent least subject to alteration in this context is remifentanil; however the drugs' potency has other inherent dangers. Other agents must only be used with caution and close patient monitoring. Amitriptyline, carbamazepine and valproate should be avoided as the risk of fulminant hepatic failure is higher in this population, and methadone is contraindicated in the presence of severe liver disease.

Trauma is the leading non-obstetric cause of maternal death. Optimal management of the pregnant trauma patient requires a multidisciplinary approach. The anaesthetist and critical care physician play a pivotal role in the entire continuum of fetomaternal care, from initial assessment, resuscitation and intraoperative management, to postoperative care that often involves critical care support and patient transfer. ⋯ Recognizing and understanding the mechanisms of injury, the factors that may predict fetal outcome, and the pathophysiological changes that can result from trauma, will allow early identification and treatment of fetomaternal injury. This in turn should improve morbidity and mortality. A framework for the acute care of the pregnant trauma patient is presented.
