postoperative sore throat and subglottic injury after mcgrath mac videolaryngoscopic intubation with versus without a stylet in patients with a high mallampati score a randomized controlled trial
BMC Anesthesiology, 2019Co-Authors: Hyun Kyu Yoon, Hyongmin Oh, Hee-pyoung ParkAbstract:A tracheal tube stylet can be used to assist successful tracheal intubation, especially during videolaryngoscopic intubation because videolaryngoscopes with a Macintosh-type blade such as McGrath® MAC videolaryngoscope have more acute angle than conventional Macintosh laryngoscope. However, the use of a stylet during tracheal intubation can raise concerns about stylet-induced postoperative airway complications, such as sore throat, subglottic injury, and hoarseness. In this study, we compared the incidence of postoperative airway complications after McGrath® MAC videolaryngoscopic intubation with versus without a stylet in patients with a high Mallampati score. In 104 patients with Mallampati score III or IV and who were scheduled for lumbar or thoracic spine surgery, McGrath® MAC videolaryngoscopic intubation was performed either with a stylet (group S, n = 52) or without a stylet (group N, n = 52). The primary outcome measure was the incidences of sore throat evaluated at 1 and 24 h postoperatively. Secondary outcome measures were the incidences of subglottic injury and postoperative hoarseness. The incidence of CL grade III in group S and N was 3.8 and 5.8%, respectively. No patient showed CL grade IV. The incidences of sore throat at 1 (26.9 vs 19.2%, P = 0.485) and 24 h (17.3 vs 13.5%, P = 0.786, respectively) postoperatively were not significantly different between the group S and N. However, the incidence of subglottic injury was significantly higher in the group S, compared with the group N (65.4 vs 42.3%, P = 0.030). The incidence of postoperative hoarseness did not differ significantly between the two groups. The use of a stylet during McGrath® MAC videolaryngoscopic intubation did not have a significant impact on the incidence of postoperative sore throat in patients with a high Mallampati score. Avoiding the use of a stylet during intubation with McGrath® MAC videolaryngoscope may reduce the incidence of subglottic injury in such patients.

CCIS - A Service Identifier parsing mechanism for Universal Network based on BHO
2012 IEEE 2nd International Conference on Cloud Computing and Intelligence Systems, 2012Co-Authors: Futao Zhao, Jianfeng Guan, Changqiao Xu, Hongke ZhangAbstract:In Universal Network, SID (Service Identifier) is the unique description for Service or resource without any locator messages, which is different from URL (Universal Resource Locator) on the Internet. The SID parsing mechanism plays the most important role in Universal Network. In this paper, we propose a SID Parsing mechanism (SIDP) by making use of BHO plug-in to parse SIDs into corresponding CID (Connection Identifier). By collecting the SIDs required from the Internet Explorer browser in Windows OS, SIDP parses the SIDs into corresponding CIDs so as to access Service or obtain resource for users. Experimental results show that SIDP system can easily and accurately parse SID into CID and will efficiently reduce the load of server especially to some popular Services and resources.

GLOBECOM Workshops - The multicast Service model for Next Generation Internet based on Identifier/Locator Separation
2012 IEEE Globecom Workshops, 2012Co-Authors: Jianfeng Guan, Wei Quan, Huachun Zhou, Hongke ZhangAbstract:The traditional multicast Service is based on the host group model, which transmits the packets to a set of receivers with a single destination address. In this model, anyone can send or receive the multicast packets once it joins the multicast group. As a result, the multicast Service is difficult to deploy due to the lack of effective authentication and accounting mechanisms. The recent development of the new Internet architecture based on the Identifier/Locator Separation mechanisms brings a promising opportunity to improve the multicast Service model. In this paper, we propose a Multicast Service model based on Identifier/Locator Separation (MILS) mechanism. This model introduces Multicast Service Identifier (MSI) and Multicast Group Identifier (MGI) to identify the multicast membership and the multicast delivery. Besides, it utilizes Multicast Controller (MC) to maintain the mapping between MSI and MGI to provide the authentication and accounting functions, so as to satisfy the different requirements of multicast Services. We evaluate its performance by simulations, and analyze its scalability in terms of the group number and session density. The results show that the MILS can reduce the multicast states and improve the performance of multicast Services.

SIDMAP:A Service-oriented Mapping System for Loc/ID split Internet Naming
Journal of Communications, 2011Co-Authors: Daochao Huang, Dong Yang, Fei Song, Hongke ZhangAbstract:While locator/Identifier split makes Internet routing more scalable, the promise of a mapping system that resolves a Service to corresponding location is yet to be realized. Part of the challenge is due to most current approaches only focusing on how to find the location of a host, not the location of a Service, which make these systems rely on extra naming system to provide applications the requested Service's location and introduce complex load interactions between the locator/Identifier mapping system and naming system. Another challenge is due to the vast majority of current Internet usage changed from host-centric applications to data retrieval and Service access, traditional domain name system (DNS) is unable to support today's Internet needs such as Service migration and composition. We introduce SIDMAP--a novel,efficient Service-oriented naming scheme for incorporating Service Identifier/Identifier mapping system that returns appropriate locators in response to mapping requests for specific Service Identifiers,Service migration and Service composition into one system. According to the result of evaluations, our mechanism has good scalability and low resolution latency.

An overview of future information network research
2010 International Conference on Advanced Intelligence and Awareness Internet (AIAI 2010), 2010Co-Authors: Hongke ZhangAbstract:Summary form only given. Due to historical reasons, the original model of existing information networks is that one network corresponds to one main Service, and this mode can't adapts well to increasing multi-demands of networks and Services. So network architecture should be redesigned urgently based on new network concept and protocols. We have studied the main issues in future information network, and give the new architecture of future information network. According to research on theories of layer division of current various information networks, we find that the structure of every network can be divided into two basic layers, one is Service layer and the other is network layer. Therefore we propose a new two-layer architecture model, that is "Pervasive Service Layer" and "Switching and Routing layer". On "Switching and Routing layer", we conclude that the routing principles of various networks are similar. They fulfill data exchanging and forwarding and have only few differences in data formats and Services supported. So we propose generalized switching and routing theory, separating and mapping of access Identifier, which is the core of universal network model and theory. On "Pervasive Service Layer", we find that the principles of various networks are similar: all Services (businesses) set up link first, then the link selects routes based on the switching and routing principle, and realize data transportation. Based on this similar principle, we propose the parsing and mapping theory between "Service Identifier" and "connection Identifier", which is the core of pervasive Service model and theory, addressing the pervasive Service issue.
