Use of Virtual Reality as a Surrogate for Parental Presence During Anesthetic Induction: A Case Report.
Virtual reality (VR), a computer-generated simulation of a 3-dimensional environment, is a relatively new method of providing distraction before and during procedures. We describe the use of a VR multiuser application, Oculus Rooms, to calm an anxious 10-year-old boy during transportation to the operating room and induction of anesthesia. The use of VR could lessen the perioperative anxiety of children by maintaining a virtual child-parent connection while avoiding the potential drawbacks to having parents actually in the operating room before and during induction of anesthesia. The success of this novel technique has important implications for future clinical trials and practice.

Here we present the case of a 76-year-old woman with pancreatic cancer receiving epidural analgesia for chronic cancer pain treatment. Attempts of running the epidural catheter sequentially resulted in unexpected and extensive sensory block together with sympathicolysis but insufficient pain control. ⋯ The MRI showed subdural catheter displacement with extensive liquid accumulation in the subdural space and consequent significant spinal cord compression. Findings normalized after removing the subdural catheter.

Gastric Ultrasound Imaging to Direct Perioperative Care in Pediatric Patients: A Report of 2 Cases.
Pulmonary aspiration of gastric contents carries significant risk in children in the perioperative period. Ultrasound imaging of the gastric antrum has been validated to predict gastric content and volume in both pediatric and adult patients, and yet clinical applications in pediatric patients are sparse. We report 2 cases of children presenting for elective surgery with uncertain volume of gastric contents. Bedside gastric imaging successfully identified "full stomachs," and the information was used to direct care.

Sphenopalatine Ganglion Blocks in the Management of Head and Neck Cancer-Related Pain: A Case Series.
Head and neck cancer can be painful, debilitating, and refractory to oral medications. Due to the association of the sphenopalatine ganglion (SPG) with maxillary nerve sensory fibers, SPG blocks may be used to treat the pain of the hard and soft palate, tonsils, nasal cavity, paranasal sinuses, oral gingiva, premaxillary soft tissue, maxilla, and orbital floor. We present the first case series of performing SPG blocks utilizing TX360 nasal atomizers or angiocatheters to treat head and neck cancer-related pain. Pain scores were reduced by 38% to 80% with an average pain relief duration of 23 days.

The angle correction feature in ultrasound systems is used when there is difficulty accurately aligning the Doppler beam with the flow to be interrogated. The operator can manually "correct" the angle to the actual direction of flow. ⋯ We present a case of aortic valve replacement (AVR) in which falsely high transaortic gradients were obtained immediately after separation from cardiopulmonary bypass (CPB). We recommend that there be a more prominent notification when the angle correction feature is used with machine prompts confirming when a peak velocity is obtained using angle correction.
