Along with the increasing population of elderly people in developed countries, anesthesiologists have increasing opportunities to anesthetize cancer patients in their routine work. However, no guideline of anesthesia procedures for cancer patients is available even though guidelines of operative procedures have been formulated for different types of cancer. This review provides recent findings related to the optimal choice of anesthetics and adequate anesthesia management for cancer patients. ⋯ Accumulated basic and clinical data suggest that total intravenous anesthesia with propofol, cyclooxygenase antagonists, and regional anesthesia can decrease negative consequences associated with perioperative immunosuppression. Volatile anesthesia, systemic morphine administration, unnecessary blood transfusions, intraoperative hypoxia, hypotension, hypothermia, and hyperglycemia should be avoided.

ReviewRenin-angiotensin system inhibitors and angioedema: anesthetic implications.
Angioedema is a serious complication of renin-angiotensin system inhibitor therapy. The incidence is 0.1-0.7%. It consists of nonpitting edema and involves the face and lips. In severe cases, it extends to pharyngeal and laryngeal structures. ⋯ Trauma of the airway, especially during difficult intubation, may precipitate severe angioedema. In cases with laryngeal involvement, fiberoptic intubation may be necessary. After the episode of angioedema, lifetime discontinuation of all renin-angiotensin inhibitors may be warranted.

Anesthesiologists may face problematic situations when patients are close to death, in which clinical problems, decision-making processes, and ethical issues are often interconnected and dependent on each of them. The aim of this review is to assess the recent literature regarding the anesthesiological role for advanced cancer patients. ⋯ Anesthesiologists should be competent in all aspects of terminal care, including the practical and ethical aspects of withdrawing different modalities of life-sustaining treatment and the use of sedatives, analgesics, and nonpharmacologic approaches to easing the suffering of the dying process. More research is needed to provide models which should be spread in the scientific community to afford this difficult task.

ReviewEpidural analgesia and maternal fever: a clinical and research update.
Maternal fever following epidural analgesia complicates up to one-third of nulliparous labors. Although generally benign, maternal fever is associated with both excess healthcare costs and an increased risk of adverse maternal and neonatal outcomes; therefore, this topic is of interest to anesthesiologists, obstetricians and pediatricians alike. The purpose of this review is to examine the latest research on the topic of epidural-related maternal fever, with special focus on the clinical relevance of new information. ⋯ Significant research advances were made in the last 18 months around the topic of epidural-related fever, but major gaps in knowledge persist especially with understanding the precise mechanism. The most pressing area of research is the development of well tolerated and effective prophylactic interventions to prevent maternal and fetal exposure to hyperthermia and inflammation.

ReviewPreoperative evaluation, premedication, and induction of anesthesia in infants and children.
Preparation for and induction of anesthesia in children has evolved significantly over the last decade, with particular reference to the reduction of perioperative anxiety reduction by nonpharmacologic and pharmacologic means. Several new large population studies and meta-analyses further scrutinize the current techniques. ⋯ Larger studies still need to be conducted before wide-scale application of many nonpharmalogical interventions such as parental acupuncture. Similarly, more investigation should be done on outcomes such as onset, emergence, and discharge times, as well as the postoperative response with reference to emergence delirium and postoperative nausea and vomiting prevention to outline the differences among sedative premedications such as midazolam, clonidine, and dexmedetomidine.
