Persistent extravascular bubbles on radiologic imaging after recompression treatment for decompression sickness: A case report

Decompression illness: a comprehensive overview

Decompression illness is a collective term for two maladies (decompression sickness [DCS] and arterial gas embolism [AGE]) that may arise during or after surfacing from compressed gas diving. Bubbles are the presumed primary vector of injury in both disorders, but the respective sources of bubbles are distinct. In DCS bubbles form primarily from inert gas that becomes dissolved in tissues over the course of a compressed gas dive. During and after ascent ('decompression'), if the pressure of this dissolved gas exceeds ambient pressure small bubbles may form in the extravascular space or in tissue blood vessels, thereafter passing into the venous circulation. In AGE, if compressed gas is trapped in the lungs during ascent, pulmonary barotrauma may introduce bubbles directly into the pulmonary veins and thence to the systemic arterial circulation. In both settings, bubbles may provoke ischaemic, inflammatory, and mechanical injury to tissues and their associated microcirculation. While AGE typically presents with stroke-like manifestations referrable to cerebral involvement, DCS can affect many organs including the brain, spinal cord, inner ear, musculoskeletal tissue, cardiopulmonary system and skin, and potential symptoms are protean in both nature and severity. This comprehensive overview addresses the pathophysiology, manifestations, prevention and treatment of both disorders.

Perioperative Nursing Care of Vascular Decompression for Trigeminal Neuralgia under AR Medical Technology

AR technology, also known as AR or virtual reality, refers to a technology that combines and allows interaction of the virtual world on the display system with the real world through the position and angle of the camera video and image analysis technology. This technology is different from VR technology, and its characteristics can be easily explained as follows: when using AR technology, the user's eyes can see not only the real world but also the virtual world derived from the computer through things in the real world. At present, AR has been widely used in education, engineering, entertainment, and medical fields. In order to provide better perioperative care and bring patients a good nursing experience, this article mainly introduces the perioperative care of vascular decompression in the treatment of trigeminal neuralgia by augmented reality medical technology, in order to provide better care for patients with trigeminal neuralgia. This article proposes the perioperative nursing research method of vascular decompression for the treatment of trigeminal neuralgia under AR medical technology, including an overview of trigeminal neuralgia, perioperative related research, and AR medical technology algorithms, and designs related experiments to study whether AR medical technology can bring good news to nursing. Experimental results show that 96% of patients believe that with the enhancement of realistic medical technology, perioperative vascular decompression care for trigeminal neuralgia can help them recover faster and can be gradually popularized.
