Difficulties in pediatric airway management are common and continue to result in significant morbidity and mortality. This review reports on current concepts in approaching a child with a difficult airway. ⋯ The healthy child with an unexpected airway problem requires clear strategies. The 'impaired' normal pediatric airway may be handled by anesthetists experienced with children, whereas the expected difficult pediatric airway requires dedicated pediatric anesthesia specialist care and should only be managed in specialized centers.

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.

To guide the optimal fluid management during cesarean delivery. The article focuses on fluid management to prevent hypotension during cesarean delivery performed under spinal anesthesia and excludes obstetric hemorrhage. ⋯ Current evidence suggests that combining a prophylactic vasopressor regimen with HES preloading, HES coloading or crystalloid coloading is the best method of preventing maternal hypotension after the initiation of spinal anesthesia. Crystalloid preloading is clinically ineffective and thus should no longer be used.

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.

Common colds are infections of mostly viral origin that frequently occur in childhood. The overall anesthetic risk in children with respiratory tract infections is increased because of the increased incidence of perioperative respiratory adverse events (PRAEs). Although the morbidity and mortality of PRAE are low when managed by experienced anesthesiologists, careful preoperative assessment and perioperative anesthetic care are indispensable. ⋯ Children with a cold can be safely anesthetized under certain circumstances; however, anesthesia in children with symptomatic infections with wheezing, purulent secretion, fever and reduced general condition should be postponed for at least 2 weeks. Anesthetic treatment options for children with infection of the upper airway with a runny nose and cough include preoperative inhalational therapy with salbutamol, avoidance of endotracheal intubation whenever possible, use of a face mask or laryngeal mask, intravenous induction with propofol and avoidance of desflurane. Prevention, early recognition and immediate treatment of complications by an experienced anesthesiologist are crucial.
