Although anxiolytic-sedative agents are used preoperatively since the advent of anesthesia, many aspects of this treatment, including the intended effects among which anxiolysis, effectiveness, and optimal agents, remain unclear. The objective of this study was to provide insight into the preoperative use of anxiolytic-sedative agents in the Netherlands and to relate the administration of these agents to the anxiolytic-sedative state of patients. ⋯ Anxiolytic-sedative agents are used preoperatively in a substantial number of patients in the Netherlands, and the pharmacokinetic characteristics of many agents are not optimal of their intended use. In addition, we found no relationship with reduced anxiety. This study stresses the need for clear guidelines on preoperative use of anxiolytic-sedative agents.

Case Reports
Interventional and multimodal pain rehabilitation in a child with meralgia paresthetica.
Meralgia paresthetica is a chronic pain syndrome that is extremely rare in the pediatric population. It is manifested by hypesthesia or pain in the distribution of the lateral femoral cutaneous nerve (LFCN) and is typically caused by entrapment as the nerve passes deep to the inguinal ligament. This sensory mononeuropathy is rare in children and diagnosis is typically delayed, often leading to prolonged functional impairment and unnecessary medical testing. ⋯ A second LFCN block was performed with complete resolution of symptoms and restoration of function. The patient remains pain-free and has returned to walking, running, and competitive sports. The primary goal of pediatric chronic pain management, regardless of pain etiology, is early restoration of function to avoid prolonged absence from school, sports, or other productive activities and limit the psychological burden of chronic disease.

Obese patients regularly present for surgery and have greater hypoxemia risk. This study aimed to identify the risk and incidence of intraoperative hypoxemia with increasing body mass index (BMI). ⋯ Despite existing practices to limit hypoxemia in obese patients, the odds of experiencing intraoperative hypoxemia increase significantly with increasing categories of BMI. Further practices may need to be developed to minimize the risk of intraoperative hypoxemia in obese patients.

Case Reports
Elective use of the Ventrain for upper airway obstruction during high-frequency jet ventilation.
The safety of high pressure source ventilation (jet ventilation) is dependent upon upper airway patency to facilitate adequate passive expiration and prevent increasing intrathoracic pressure and its associated deleterious sequelae. Distortions in airway anatomy may make passive expiration inadequate or impossible in some patients. We report the elective use of the Ventrain device to provide ventilation in a clinical setting of upper airway obstruction in a patient with post radiation fibrosis that had previously prevented passive expiration during attempted high pressure source ventilation.

To evaluate perioperative dual antiplatelet therapy management in patients with previously placed coronary stents. ⋯ This study revealed suboptimal adherence to current perioperative antiplatelet management guidelines in patients with coronary stents. The lack of adherence to current guidelines is concerning and could be used to support the notion of an anesthesiologist-led Perioperative Surgical Home.
