Practice of multi-campus hospital management based on integrated interconnected and digital intelligence-based service system / 中华医院管理杂志

Medical homogenization in multi-campus hospital plays an essential role in leveraging the advantages of public hospitals, promoting the expansion of high-quality medical resources and balancing regional layout. The Second Affiliated Hospital Zhejiang University School of Medicine deeply used digital intelligence technology to build a new integrated mobile health service system consisting of internet hospital and 5G intelligent applications, which empowered medical efficiency in multi-campus hospital. This system broke the limitations of inconsistent medical resources, unbalanced discipline layout, and insufficient information connectivity in the construction of multi-campus hospitals, and achieved remarkable results in practice. It could provide reference for the multi-campus construction of other large public hospitals.

A primary study on construction of urban unmanned aerial vehicle emergency blood distribution system / 中华急诊医学杂志

Objective:To explore the feasibility and effectiveness of the construction of urban unmanned aerial vehicle (UAV) blood distribution system, and to provide a novel way for the distribution of emergency blood.Methods:The study was completed in Hangzhou from April 2019 to January 2021, and the main participants were from the Second Affiliated Hospital of Zhejiang University School of Medicine, Zhejiang Province Blood Center and Hangzhou Fast Ant Network Technology Co., Ltd. Firstly, an unmanned aircraft delivery system was built for urban emergency blood and a special blood storage box for drones were developed. The drone was used to deliver blood products from Zhejiang Province Blood Center to Binjiang Campus, the Second Affiliated Hospital of Zhejiang University School of Medicine, and the following indicators were obtained: (1) flight time of the drone blood delivery; (2) real-time temperature of blood products during transportation; (3) Baidu map software was used to measure the blood delivery time of road traffic, which was compared with the flight time of the drone.Results:The urban drone blood delivery system consists of intelligent logistics drones, cryogenic blood storage tanks, unmanned logistics hub stations, and cloud-based operation control platforms. The drone route distance from Zhejiang Provincial Blood Center to Binjiang Campus, the Second Affiliated Hospital of Zhejiang University School of Medicine was 2.36±0.06 km, and the ground distance was 5.8 km, with 27 flights from April 12, 2019 to January 29, 2021, and the drone flight time was, shorter than the road travel time for a round trip [(6.37±0.35) min vs. (17.00±1.94) min]. At different time points of the day, UAV blood delivery could save 15.98-4.28 min, with an average saving of 10.62±1.87 min. Conclusions:Urban UAV blood delivery systems have the advantages of being fast, unaffected by ground traffic conditions, and can ensure the safety of blood products during transportation, and are worthy of further exploration.

Construction of Pre-hospital and In-hospital Emergency Medical Service System Based on 5G Communication Technology / 中华急诊医学杂志

Objective@#To explore a new platform for pre-hospital and in-hospital emergency medical services based on a new generation of 5G communication technology, providing a basis for further improving the level of emergency medical services.@*Methods@#This study was conducted at the Second Affiliated Hospital of Zhejiang University School of Medicine from October 2017 to April 2019. Based on the latest requirements of emergency medical services at home and abroad, the cross-enterprise and multi-disciplinary technical forces were organized to build platform. Firstly, to determine the process of pre-hospital and in-hospital emergency medical services, various modules and technical routes were constructed under 5G conditions and individual technologies were tested one by one. Then they were gradually integrated into two platforms of ambulance and hospital emergency. Finally, the simulation test is carried out under the support of the whole 5G network.@*Results@#The pre-hospital and in-hospital emergency medical service platform based on 5G technology comprises of 5G ambulance, 5G panoramic VR real-time display system, 5G remote ultrasonic examination system, medical drone system, and 5G emergency command platform. 5G ambulance contains medical equipments such as multi-function monitor, ventilator, defibrillation monitor, portable B-ultrasound, high-definition remote video interactive system based on 5G network, VR immersive real-time panoramic experience system, and GPS positioning system. 5G panoramic VR real-time display system includes VR panoramic camera and VR glasses. The wearer with VR glasses can view the real-time situation on the ambulance, which makes a preliminary judgment on the patient's condition and provides rescue guidance. 5G remote ultrasonic examination system integrates robot technology, real-time remote control technology, and ultrasonic imaging technology. The specialist can control the movement of the ultrasonic probe set on the 5G ambulance by manipulating the mechanical arm. The patient's image and color super-picture can also be simultaneously returned to the specialist. The medical drone system enables the medical resources to be allocated in the shortest possible time through the 5G networked drones, so as to eliminate the delay caused by traffic congestion. 5G emergency command platform can integrate, transmit, and display data from multiple sources and forms through web pages in assistance of AI and internet of things.@*Conclusions@#The new platform for pre-hospital and in-hospital emergency medical services based on 5G technology can realize more fluent information exchange in pre-hospital and in-hospital, and realize the functions that are difficult to achieve under the previous network conditions.

giant ganglion cyst of hip joint causing lower limb edema

lower limb edema caused by a gaint ganglion cyst of hip joints, Rather than deep venous insufficiency or lymphedema, is unusual particularly for guiding clinical practice. In this study, we present a rare case of a 76-year old man with a 3-month history of progressive swelling of right lower extremity and 2-month history of a known inguinal mass, which was initially thought as hemangioma by using ultrasound. But, subsequent computed tomography examination and exploration surgery revealed a gaint ganglion cyst compressing the right femoral vein. Resection of the cyst led to complete resolution of symptoms postoperatively. To the best of our knowledge this is a very rare case of gaint ganglion cyst of hip joint origin causing lower limb edema in the literature
