The role of helicopters in trauma management must be considered in the context of the provision of sophisticated, high-quality trauma care. The present review examines the evolution of systems of trauma care, the value of advanced life support (ALS), and the role of the Helicopter Emergency Medical Service (HEMS) in improving outcomes. ⋯ There is a role for HEMS as part of a modern trauma system, in particular in bringing ALS skills and access to expert medical care to the rural accident scene or hospital at distances of up to 160 km. It is of greatest value when it is integrated into a well-organized ambulance service and emergency system with good triage and close medical supervision.

The optimal method of restoring intestinal continuity after rectal resection has been controversial. This study aims to compare the morbidity, mortality and survival of patients having either single-stapled (SS) or double-stapled (DS) colorectal anastomoses following resection of the rectum for cancer. ⋯ These results suggest that the double-stapling technique is as safe as the single-stapling technique for constructing an anastomosis after excision of the rectum for cancer, in terms of the risk of leakage, the development of an anastomotic stricture, or local recurrence.

The philosophy and practice of minimally invasive surgery have fundamentally altered the practice of general and gynaecological surgery, and are currently transforming the practice of neurosurgery. The goal of minimally invasive surgery is to reduce tissue disruption and thus morbidity. This is a review of the development, applications, and benefits of minimally invasive neurosurgery, and its wider surgical implications. ⋯ Minimally invasive neurosurgery is a major force in contemporary neurosurgery and many of the current neurosurgical applications will have far-reaching effects on the practice of surgery in general.

New justification for the use of regional anaesthesia, either alone or in combination with general anaesthesia, has been provided with reports of some unexpected influences on outcome. A reduction in the incidence of postoperative thrombotic episodes and vascular graft occlusion is strongly suggested in patients with generalized vascular disease. Application of a variety of drugs, including local anaesthetics, opioids and adrenergic agonists, in the region of the spinal cord reduces afferent input during surgery and also the metabolic stress response. ⋯ Premedication with opioid and other analgesics may also enhance this pre-emptive effect. New general anaesthetic and analgesic drugs are available that are more suited to these combined techniques. They have shorter duration of action so that plasma concentration can be rapidly adjusted to match a variable surgical stimulus.
