General anesthesia was successfully performed in a 9-year-old boy with FOP. FOP is a very rare inherited disease of the connective tissue, characterized by progressive heterotopic ossification of skeletal muscles, tendons, and ligaments. Trauma and invasive medical procedures can induce heterotopic ossification. ⋯ Regarding the airway management in general anesthesia, excessive stretching of the jaw and extension of the head may lead to the ankylosis of the temporo-mandibular joint and the neck stiffness. Ankylosis of the costvertebral joints induces restrictive ventilatory impairment, which causes atelectasis and lung infection in the perioperative period. Relating to anesthetic management for a child with FOP, anesthesiologists should keep in mind the prevention of exacerbation of the symptoms and subsequent impairment of activities of daily living postoperatively.

Preoperative fasting is principally intended to minimize the risk of pulmonary aspiration of gastric contents and facilitate the safe and efficient conduct of anesthesia. Liberalization of fasting guidelines has been implemented in most countries. In general, clear fluids are allowed up to 2h before anesthesia, and light meals up to 6h. ⋯ These guidelines apply to healthy children only. Exclusion criteria included obesity, diabetes, gastroesophageal reflux, ileus, bowel obstruction and emergency care. In particular, trauma and other emergency cases are at higher risk for aspiration regardless of fasting interval and should be managed appropriately.

Perioperative fluid therapy aims to provide water, electrolytes and calorie to maintain metabolic homeostasis. The landmark article in which Holliday and Segar proposed the rate and composition of parenteral maintenance fluids for hospitalized children is used to the fluid management for the pediatric surgical patient. ⋯ Routine intraoperative dextrose administration is no longer necessary. We should ultimately change our approach according to major intraoperative fluid shifts by rational, monitored, goal-directed combination of both crystalloid and colloid therapy, similar to that occurring in adult surgical patients.

Fever and upper respiratory tract infections (URI) are frequently-encountered preoperative comorbidities. Whether or not to proceed with anesthesia for a child with common cold is still a continuing dilemma for anesthesiologists. We, anesthesiologists often feel uncomfortable in making a decision whether or not to proceed because URI is associated with perioperative respiratory adverse events (PRAEs) and there are no definite rules to proceed with or postpone a case. ⋯ Moreover, because children per se are vulnerable to PRAEs, we cannot reduce the risk to zero even without a URI. Therefore, we should be familiarized with how to cope with PRAEs. In making a decision to proceed with or postpone the case, it is important to take various factors together into account, and the decision ultimately depends on whether or not we feel "Yes, we can".

Procedural sedation and analgesia comprise an integral part of high quality tertiary care in pediatrics. All patients undergoing procedural sedation should be evaluated as extensively as in patients receiving general anesthesia, and an appropriate fasting time should also be considered. Since cardio-respiratory side effects are inevitably associated with sedative medications, (1) only medical personnel with an expertise in the use of these medications should manage procedural sedation, and (2) additionally, the choice of medication should be decided on a case-by-case basis as no single sedation recipe has proven superior to others. ⋯ Following the procedure, medical staff should also monitor patients until full recovery is achieved. Pediatric anesthesiologists should be involved in the sedation procedure for patients with complicated medical histories. Finally, care should be taken to avoid ferrous equipment when performing sedation in an MRI suite.
