Anaesthetic assessment and management of cardiac patients for non-cardiac surgery. Part 2: Management.

In an earlier article in this journal (June 1999) we discussed the risk that the presence of cardiac disease poses to patients undergoing non-cardiac surgery. We outlined factors in the patient's medical history, examination findings and the value of various tests in arriving at an overall assessment of risk for any given patient. In this article we concentrate on the management of these patients as they undergo surgery itself. We shall consider what measures may usefully be employed in order to minimise the risk of an adverse cardiac event occurring in the perioperative period.

Relationship between maternal and neonatal vitamin B6 metabolism: perspectives from enzyme studies.

Enzymes involved in vitamin B6 metabolism, i.e., pyridoxal kinase, pyridoxamine (pyridoxine) 5'-phosphate oxidase, and pyridoxal 5'-phosphate phosphatase, were assayed in hemolysates prepared from cord, maternal, and control blood samples. Mean cord and control pyridoxamine (pyridoxine) 5'-phosphate oxidase activities were significantly higher than maternal activities (p less than 0.001 and p less than 0.05, respectively). A significant correlation (p less than 0.001) was observed between maternal and cord vitamin B6-metabolizing enzymes. Cord pyridoxal 5'-phosphate levels correlated significantly with maternal pyridoxal 5'-phosphate levels (p less than 0.001) and with cord pyridoxal kinase activity (p less than 0.05). Maternal pyridoxal 5'-phosphate levels appear to be the most important factor determining fetal vitamin B6 status.

Pathophysiological basis of burn management.

Despite increased public awareness of the dangers of fire, burns remain a part of everyday life. Most accident departments will see one or more burn victims each day and, although not common, major burns still occur. In this and a second article we review the pathophysiology of thermal injury and describe the early treatment of a major burn victim.

The early management of large burns.

The first article in this series (Vol 52 (11), p.583) discussed the pathophysiological processes involved in burn injury. This article describes the early management of large burns, in which treatment is considered in four stages: resuscitation, assessment, further care and transfer. The mnemonic 'RAFT' is suggested as a means of assisting recall of the management process.

Evaluation of the impact of a bedside terminal system in a rapidly changing community hospital.

The impact of a bedside terminal system implemented in a community hospital was evaluated using a one-group before-and-after design. Contrary to predictions, the amount of time registered nurses spent in direct care and the positiveness of registered nurses' attitudes toward bedside terminal technology decreased after the implementation. Registered nurse overtime decreased in accordance with the prediction and unit medication errors remained unchanged. The internal validity of these results was threatened by organizational changes that directly and indirectly affected the study unit. Recommendations are made for conducting evaluation research in a rapidly changing hospital environment.

Humerus shaft fractures in young children: accident or abuse?

We performed a retrospective review of 34 humerus shaft fractures (HSFs) in children younger than 3 years to determine the frequency of child abuse in young children with this injury. Data were obtained from hospital records (including previous and subsequent emergency, clinic, and inpatient notes), radiographs, and county childprotective services. Cases were reviewed independently by four physicians and were classified as probable abuse, probable not abuse, and indeterminate. Only 18% were classified as probable abuse. The history and findings other than the fracture itself were critical in establishing cause. Neither age nor fracture pattern is pathognomonic of abuse, but suspicion should remain high. A detailed history, complete physical examination, and appropriate radiographic investigation are required in every case either to make the diagnosis of abuse or to avoid the trauma of a false accusation.
