The present overview will try to summarize the most important recent studies performed on spinal analgesia for labor pain treatment and spinal anesthesia for Cesarean section. ⋯ The new local anesthetics have established their position in obstetric regional anesthesia, but it remains difficult to demonstrate a superior outcome as compared with bupivacaine. The same is true for combined spinal-epidural and ambulation. Phenylephrine seems to have become the vasopressor of choice in the treatment of hypotension following spinal anesthesia. A more appropriate treatment of hypotension combined with a low-dose technique may enhance the safety of spinal anesthesia in preeclamptic patients or cases of severe cardiac disease.

The elderly population is increasing in number each year, and more patients are presenting for anesthesia and surgery. One of the key areas for improving the care of the elderly is a better understanding of the influence of aging on drug pharmacokinetics and dynamics. ⋯ The effects of comorbidity and intercurrent medications may alter the normal anesthetic practice of the clinician's care of the elderly patient. Further studies in these key areas may lead to improved outcomes.

Anaesthetic considerations in patients with chronic pulmonary disease.
Chronic pulmonary diseases are getting more important in daily anaesthetic practice, because prevalence is increasing and improved anaesthetic techniques have led to the abandonment of previous contraindications to anaesthesia. It is therefore essential for the anaesthetist to be up to date with current clinical concepts and their impact on the conduction of anaesthesia as well as new insights into how to anaesthetise these patients safely. ⋯ Assessing the functional status of patients admitted for surgery remains a difficult task, and in patients identified as being at risk by clinical examination additional spirometry and blood gas measurements may be helpful. If there are flow limitations and signs of respiratory failure, the anaesthetist should be highly alarmed and monitor the patient closely and invasively, yet there is no reason to deny any patient a substantially beneficial operation.

Dengue fever in febrile returning travellers to a UK regional infectious diseases unit.
Background. Dengue occurs in many tourist destinations, and is increasingly imported by returning travellers. We review the epidemiology and clinical features of confirmed dengue in returning travellers presenting to a UK regional infectious diseases unit. ⋯ Conclusions. Dengue is an important cause of illness in hospitalised febrile returning travellers. It should be considered in first-time travellers, with thrombocytopenia and negative malaria films who present with symptoms soon after return.

Postoperative pulmonary complications, including pneumonia, bronchospasm, respiratory failure and prolonged mechanical ventilation, occur commonly and are a significant source of morbidity and mortality. This review will discuss the etiology of postoperative pulmonary complications and the interventions that reduce their risk. ⋯ Understanding risk factors for the development of postoperative pulmonary complications allows targeted interventions aimed at reducing their frequency and severity. Further research is needed to define the role of regional analgesic and anesthetic techniques in reducing postoperative pulmonary complications, and also to define the nature of risk factors and develop better predictive models of patients at risk of developing postoperative pulmonary complications.
