Methods: this study will adopt the method of sampling survey and group study. Firstly, the patients participating in the study will be selected by the sampling survey method. The selected objects will be patients undergoing ovarian cancer surgery in our hospital. The sampling time will be from January 2021 to 2022. In January of this year, the number of samples was 300. After sampling, they were divided into groups according to the random number table method. All patients were divided into control group and experimental group. One half of the patients received routine care and was included in the control group. Fast recovery surgical nursing was included in the experimental group, and the first eating time, first defecation time, hospitalization time, nursing satisfaction and complication rate after nursing were compared between the two groups. Results: from the aspect of the first eating time, the first eating time of the experimental group was lower than that of the control group, and the difference between the two groups of data was significant (P<0.05). The first defecation time of the patients was lower than that of the control group, and the difference between the two groups of data was significant (P<0.05). The difference was significant and statistically significant (P<0.05);from the comparison of the nursing satisfaction of the two groups of patients, the nursing satisfaction of the experimental group was higher than that of the control group, and the difference between the two groups of data was significant and statistically significant (P<0.05);from the comparison of the incidence of complications between the two groups, the incidence of complications in the experimental group was lower than that in the control group, and the difference between the two groups was significant (P<0.05). Conclusion: rapid recovery surgical nursing for ovarian cancer patients after surgery can effectively improve their postoperative physical recovery, improve the treatment effect, and shorten the length of hospital stay.展开更多

This study was to evaluate the effect of fast track strategy on patients subjected to pancreaticoduo-denectomy (PD) from an individual unit during transit from low to a high volume center. METHODS: A total of 142 PD patients who had been subjected to fast track strategy between June 2008 and September 2012 were compared with 46 patients who had received convention-al surgery between January 2006 and May 2008. Comparative analysis was made of postoperative complications, postopera-tive recovery, length of hospital stay and patient readmission requirement. RESULTS: The patients subjected to fast track strategy had a faster recovery and a shorter hospital stay than those who were treated conventionally (7.8 vs 12.1 days). The intraoperative events like operative blood loss (417.9±83.8 vs 997.4 ±151.8 mL, P<0.001), blood transfused (a median of 0 vs 1 unit,P<0.001) and operative time taken (125 vs 245 minutes,P<0.001) were signiifcantly lower in the fast track group. The frequency of pancreatic ifstula (4.9% vs 13.0%) and delayed gastric empty-ing (7.0% vs 17.4%) was also signiifcantly reduced with fast track treatment. Nevertheless, the readmission rate (11.3% vs 6.5%) was found relatively higher within the fast track group. However, increased readmission rates in this study seem to be independent of fast track protocol. CONCLUSIONS: This preliminary analysis suggests that the fast track approach might be beneifcial to the well-being of the patients after PD, for it accelerates the immediate clinical recovery of patients and signiifcantly shortens their length of hospital stay.展开更多

Methods: this paper mainly selects patients who received knee arthroscopy anterior cruciate ligament reconstruction in our hospital from January to December 2021 as the research subjects, including 112 cases, divided into control group (56 cases) and experimental group (56 cases). The main method used in the two groups was the conventional treatment concept;the experimental group was mainly treated with the concept of fast recovery surgery. After the clinical treatment, the application value and effect of the concept of fast recovery surgery were evaluated from the Judet and Lysholm scores, postoperative recovery index, satisfaction and infection rate. Results: the Judet and Lysholm scores were compared, and the excellent and good rates were compared between the two groups at 3 months and 6 months after surgery. Among them, the postoperative score of the experimental group was significantly higher than that of the control group, and the difference between the two groups was statistically significant (P<0.05). The recovery from various indicators in the control group and the experimental group, such as: the length of hospital stay in the control group was longer than that in the experimental group;the recovery time of the knee joint range of motion in the control group was relatively longer;the VAS and BI scores in the experimental group were better than those in the control group. Comparing the satisfaction of patients between the two groups, the satisfaction of patients in the experimental group was significantly higher than that in the control group, and the two groups were statistically significant (P<0.05). Comparing the infection rates of the two groups, the infection rate of the control group was 14.29%, and the infection rate of the experimental group was 1.79%, which fully demonstrated that there was a statistically significant difference in the infection rates between the two groups (P<0.05). Conclusion: in the process of patients undergoing knee arthroscopy anterior cruciate ligament reconstruction, the use of fast rehabilitation surgery concept is more effective than traditional treatment, which can effectively speed up the patients rehabilitation process, shorten the patients hospitalization time and recovery time, and improve the patients experience. Satisfactions with clinical treatment improve patients limb function and then obtain higher quality of life.展开更多

Methods: according to the touch-ball method, 120 patients who underwent laparoscopic adrenal tumor resection in our hospital from April 2018 to June 2021 were divided into an observation group and a control group, with 60 cases in each group. The control group was given routine nursing intervention, while the observation group was combined with the FTS concept on the basis of routine nursing intervention. The clinical indicators, visual analogue scale (VAS) score, psychological state score, complication rate and nursing satisfaction were compared between the two groups. Results: the clinical indicators in the observation group were shorter than those in the control group (P<0.05);the VAS score in the observation group after nursing was lower than that in the control group (P<0.05);the psychological state score in the observation group after nursing was higher than that in the control group (P < 0.05);the incidence of complications in the observation group was lower than that in the control group (P < 0.05);the nursing satisfaction score in the observation group was higher than that in the control group (P < 0.05). Conclusion: the application of FTS concept in the perioperative period for patients undergoing laparoscopic adrenal tumor resection can speed up the patients recovery process, relieve the patients pain, reduce their psychological pressure, and at the same time reduce the risk of postoperative complications, and the patients nursing satisfaction is relatively high. It is recommended for clinical application.展开更多

However, attackers can lead catastrophic results to the whole network using manipulated flooding packets, called the data-to-control-plane saturation attacks. The existing methods, using centralized mitigation policies and ignoring the buffered attack flows, involve extra network entities and make benign traffic suffer from long network recovery delays. For these purposes, we propose LFSDM, a saturation attack detection and mitigation system, which solves these challenges by leveraging three new techniques: 1) using linear discriminant analysis (LDA) and extracting a novel feature called control channel occupation rate (CCOR) to detect the attacks, 2) adopting the distributed mitigation agents to reduce the number of involved network entities and, 3) cleaning up the buffered attack flows to enable fast recovery. Experiments show that our system can detect the attacks timely and accurately. More importantly, compared with the previous work, we save 81% of the network recovery delay under attacks ranging from 1,000 to 4,000 packets per second (PPS) on average, and 87% of the network recovery delay under higher attack rates with PPS ranging from 5,000 to 30,000.展开更多
