ReviewThe perioperative management of patients maintained on medications used to manage opioid addiction.
The substantial increase in prescription and illicit opioid abuse observed over the last 2 decades has significantly increased the number of patients in recovery from addiction and now maintained on opioid replacement or agonist therapy. These patients present unique challenges to perioperative pain management. ⋯ When possible, patients maintained on buprenorphine should be evaluated preoperatively to assess the feasibility of discontinuing the buprenorphine 72 h before surgery. If buprenorphine is continued during the perioperative period, patients may require significantly increased doses of standard opioids for analgesia. Patients maintained on methadone are at increased risk for respiratory-related complications and should receive a higher level of monitoring during the perioperative period. Patients who are on chronic methadone should continue their maintenance dose during the perioperative period. Where possible, nonopioid medications and regional anesthetic blockade are effective alternatives for analgesia in this population.

ReviewAnesthesia and ventilation strategies in children with asthma: part I - preoperative assessment.
Asthma is a common disease in the pediatric population, and anesthetists are increasingly confronted with asthmatic children undergoing elective surgery. This first of this two-part review provides a brief overview of the current knowledge on the underlying physiology and pathophysiology of asthma and focuses on the preoperative assessment and management in children with asthma. This also includes preoperative strategies to optimize lung function of asthmatic children undergoing surgery. The second part of this review focuses on the immediate perioperative anesthetic management including ventilation strategies. ⋯ To minimize the considerable risk of perioperative respiratory adverse events in asthmatic children, a good understanding of the underlying physiology is vital. Furthermore, a thorough preoperative assessment to identify children who may benefit of an intensified medical treatment thereby minimizing airflow obstruction and bronchial hyperreactivity is the first pillar of a preventive perioperative management of asthmatic children. The second pillar, an individually adjusted anesthesia management aiming to reduce perioperative adverse events, is discussed in the second part of this review.

This review highlights the current trends of efficient and safe perioperative pediatric pain therapy in the context of a multimodal pain therapy concept. ⋯ Safe and simple pediatric pain management in the perioperative period combines not only easy to apply and safe stepwise pain therapy itself, but also adequate pain assessment and the implementation of continuous hospital quality improvement strategies.

Postoperative nausea and vomiting (PONV) has a high incidence in children and requires prophylactic and therapeutic strategies. ⋯ Concluding from the existing guidelines and data on the handling of PONV in children at least 3 years, the following recommendations are given: outpatients undergoing small procedures should receive a single prophylaxis, outpatients at high risk a double prophylaxis, inpatients with surgery time of more than 30 min and use of postoperative opioids should get double prophylaxis, and inpatients receiving a high-risk surgical procedure or with other risk factors a triple prophylaxis (two drugs and total intravenous anesthesia). Dimenhydrinate can be used as a second choice, whereas droperidol and metoclopramide can only be recommended as rescue therapy.

ReviewIntraosseous infusion in elective and emergency pediatric anesthesia: when should we use it?
Difficulties to establish a venous access may also occur in routine pediatric anesthesia and lead to hazardous situations. Intraosseous infusion is a well tolerated and reliable but rarely used alternative technique in this setting. ⋯ Most problems in using an intraosseous infusion are provider-dependent. In pediatric anesthesia, the perioperative setting should further contribute to reduce these problems. Nevertheless, regular training, thorough anatomical knowledge and prompt availability especially in the pediatric age group are paramount to get a seldom used technique work properly under pressure. More longitudinal data on large cohorts were preferable to further support the safety of the intraosseous infusion technique in pediatric patients.
