Randomized Controlled TrialEffects of preoperative education using virtual reality on preoperative anxiety and information desire: a randomized clinical trial.
This study aimed to investigate the effect of preoperative education using virtual reality (VR) on preoperative anxiety and information desire. The participants were randomly assigned to the VR group and control group. The VR group received preoperative education using VR content describing preoperative and postoperative processes and their management, and the control group received preoperative education with traditional verbal education. ⋯ Preoperative education using VR effectively reduced preoperative anxiety and information desire. Trial registration CRIS, KCT0007489. Registered 30 June 2022. http://cris.nih.go.kr/cris/ .

Randomized Controlled TrialBlood pressure control with phenylephrine or dobutamine: a randomized controlled trial comparing effects on cerebral and paravertebral tissue oxygen saturation measured with near-infrared spectroscopy.
Preserving haemodynamics is expected to positively affect tissue oxygen saturation. We hypothesized that maintaining mean arterial blood pressure (MAP) (using phenylephrine (PE) or dobutamine (Dobu)) would equally affect regional cerebral and paravertebral tissue saturation (rScO2 and rSpvO2, respectively). Thirty-four patients were randomly assigned to receive either PE or Dobu, in order to keep MAP within 20% of the preoperative value. ⋯ Current guidelines advocate maintaining adequate systemic blood pressures to prevent spinal cord ischaemia in specific procedures. However, it is still unknown which circulatory supportive drug is more beneficial for maintaining spinal cord perfusion. Our data indicates that, when used for maintenance of blood pressure within a 20% range of preoperative values, neither phenylephrine nor dobutamine affect paravertebral tissue saturation.
