Background Patients undergoing medical procedures benefit from preprocedural education. Objective To evaluate a multisensory virtual reality preoperative educational program for patients undergoing elective cardiovascular surgical procedures with postoperative recovery in the intensive care unit (ICU) and assess its impact on patients’ outcomes and experience. Methods Patients scheduled for elective cardiovascular surgical procedures with expected recovery in the ICU were enrolled. A multidisciplinary team designed the virtual reality simulation. Educational objectives focused on patient safety, family presence, ICU machinery and activities, reorientation, and communication with the care team. Historical control patients (n = 94) underwent medical record review and were contacted to complete surveys. Virtual reality simulation patients (n = 44) underwent medical record review, viewed the simulation at a preoperative appointment, and completed surveys. The study included patients admitted from June 4, 2019, to May 12, 2022. Results Durations of postoperative sedation and mechanical ventilation were lower in patients receiving virtual reality simulation. Most patients in the virtual reality simulation group (92%) said the simulation alleviated their anxiety and helped them understand what to expect in the ICU. The simulation improved their feeling of safety and decreased their fear of the unknown. Delirium incidence was not different in the 2 groups. Conclusions Preprocedural education via virtual reality simulation can improve the experience and outcomes of patients undergoing elective cardiothoracic surgery with recovery in the ICU.

Highlights Biplane ultrasound imaging reduces need for probe manipulation during procedure. Providers note clinical benefit of biplane ultrasound imaging for vascular access. Biplane disadvantages include probe size, imaging quality, size of the screen. Thorough didactic and practical education is essential for biplane success. Abstract Background: Use of ultrasound guidance for vascular access procedures is commonplace in inpatient and outpatient care settings. Standard ultrasound probes offer the operator a single-plane view, necessitating rotation of probe to attain dual complimentary views. This mechanical probe rotation increases technical difficulty of ultrasound use. The purpose of this study is to evaluate the rate of cannulation success and efficiency of a synchronous biplane ultrasound mode in ultrasound-guided arterial line placement as compared with a standard single-view ultrasound mode in the operating room setting. Methods: Patients scheduled for elective surgery in which a radial arterial catheter would be used for hemodynamic monitoring were approached for consent to this study. Patients were randomized to either undergo placement with single-plane view versus synchronous biplane view; outcomes were recorded. Providers were provided preprocedural ultrasound education as well as the option of a short hands-on experience; their level of experience was noted. Results: Placement time of a peripheral arterial catheter was longer and required more attempts to be successful using synchronous biplane imaging as compared with single-plane imaging across providers of all skill/experience levels. Subjectively, providers noted the benefit of synchronous biplane imaging in vascular access; however, disadvantages including probe size, quality of imaging, and size of the screen were noted. Discussion: Thorough education regarding the use and functionality of biplane synchronous imaging in vascular access is essential. Additional guided-practice time with experienced operators could also be helpful to overcome the challenges observed in this study.
