Neuroprotective effect of bispectral index-guided fast-track anesthesia using sevoflurane combined with dexmedetomidine for intracranial aneurysm embolization

Dexmedetomidine has sedative, anxiolytic, analgesic, anti-sympathetic, and anti-shivering effects. Dexmedetomidine might be effective in combination with sevoflurane for anesthesia, but prospective randomized controlled clinical trials with which to verify this hypothesis are lacking. In total, 120 patients who underwent embolization of an intracranial aneurysm were recruited from Anhui Provincial Hospital and Renmin Hospital of Wuhan University of China and randomly allocated to two groups. After intraoperative administration of 2% to 3% sevoflurane inhalation, one group of patients received pump-controlled intravenous injection of 1.0 ~tg/kg dexmedetomidine for 15 minutes followed by maintenance with 0.3 ~tg/kg/h until the end of surgery; the other group of patients only underwent pump-controlled infusion of saline. Bispectral index monitoring revealed that dexmedetomidine-assisted anesthesia can shorten the recovery time of spon- taneous breathing, time to eye opening, and time to laryngeal mask removal. Before anesthetic induction and immediately after laryngeal mask airway removal, the glucose and lactate levels were low, the S100~ and neuron-specific enolase levels were low, the perioperative blood pressure and heart rate were stable, and postoperative delirium was minimal. These findings indicate that dexmedetomidine can effectively assist sevoflurane for anesthesia during surgical embolization of intracranial aneurysms, shorten the time to consciousness and extubation, reduce the stress response and energy metabolism, stabilize hemodynamic parameters, and reduce adverse reactions, thereby reducing the damage to the central nervous system. This trial was registered at the Chinese Clinical Trial Registry （http：//www.chictr.org. cn/） （registration number： ChiCTR-IPR- 16008113）.

Fast track anesthesia for liver transplantation: Review of the current practice

Historically,patients undergoing liver transplantation were left intubated and extubated in the intensive care unit(ICU)after a period of recovery.Proponents of this practice argued that these patients were critically ill andneed time to be properly optimized from a physiological and pain standpoint prior to extubation.Recently,there has been a growing movement toward early extubation in transplant centers worldwide.Initially fueled by research into early extubation following cardiac surgery,extubation in the operating room or soon after arrival to the ICU,has been shown to be safe with proper patient selection.Additionally,as experience at determining appropriate candidates has improved,some institutions have developed systems to allow select patients to bypass the ICU entirely and be admitted to the surgical ward after transplant.We discuss the history of early extubation and the arguments in favor and against fast track anesthesia.We also described our practice of fast track anesthesia at Mayo Clinic Florida,in which,we extubate approximately 60%of our patients in the operating room and send them to the surgical ward after a period of time in the post anesthesia recovery unit.

Probabilistic Global Maximum Power Point Tracking Algorithm for Continuously Varying Partial Shading Conditions on Autonomous PV Systems

A photovoltaic (PV) string with multiple modules with bypass diodes frequently deployed on a variety of autonomous PV systems may present multiple power peaks under uneven shading. For optimal solar harvesting, there is a need for a control schema to force the PV string to operate at global maximum power point (GMPP). While a lot of tracking methods have been proposed in the literature, they are usually complex and do not fully take advantage of the available characteristics of the PV array. This work highlights how the voltage at operating point and the forward voltage of the bypass diode are considered to design a global maximum power point tracking (GMPPT) algorithm with a very limited global search phase called Fast GMPPT. This algorithm successfully tracks GMPP between 94% and 98% of the time under a theoretical evaluation. It is then compared against Perturb and Observe, Deterministic Particle Swarm Optimization, and Grey Wolf Optimization under a sequence of irradiance steps as well as a power-over-voltage characteristics profile that mimics the electrical characteristics of a PV string under varying partial shading conditions. Overall, the simulation with the sequence of irradiance steps shows that while Fast GMPPT does not have the best convergence time, it has an excellent convergence rate as well as causes the least amount of power loss during the global search phase. Experimental test under varying partial shading conditions shows that while the GMPPT proposal is simple and lightweight, it is very performant under a wide range of dynamically varying partial shading conditions and boasts the best energy efficiency (94.74%) out of the 4 tested algorithms.

Fast-track rehabilitation program vs conventional care after colorectal resection:A randomized clinical trial

AIM:To compare the fast-track rehabilitation program and conventional care for patients after resection of colorectal cancer.METHODS:One hundred and six consecutive patients who underwent fast-track rehabilitation program were encouraged to have early oral feeding and movement for early discharge,while 104 consecutive patients underwent conventional care after resection of colorectal cancer.Their gastrointestinal functions,postoperative complications and hospital stay time were recorded.RESULTS:The restoration time of gastrointestinal functions in the patients was significantly faster after fasttrack rehabilitation program than after conventional care(2.1 d vs 3.2 d,P < 0.01).The percentage of patients who developed complications was significantly lower 30 d after fast-track rehabilitation program than after conventional care(13.2% vs 26.9%,P < 0.05).Also,the percentage of patients who had general complications was significantly lower 30 d after fast-track rehabilitation program than after conventional care(6.6% vs 15.4%,P < 0.05).The postoperative hospital stay time of the patients was shorter after fast-track rehabilitation program than after conventional care(5 d vs 7 d,P < 0.01).No significant difference was observed in the readmission rate 30 d after fast-track rehabilitation program and conventional care(3.8% vs 8.7%).CONCLUSION:The fast-track rehabilitation program can significantly decrease the complications and shorten the time of postoperative hospital stay of patients after resection colorectal cancer.

Fast track clinical pathway implications in esophagogastrectomy

AIM： To investigate the feasibility of fast track clinica pathway for esophageal tumor resections. METHODS： One hundred and fourteen patients with esophageal carcinoma who underwent esophagogastrectomy from January 2006 to October 2007 in our department were studied. Fast track clinical pathway included analgesia control, fluid infusion volume control, early ambulation and enteral nutrition. Nasogastric tube was removed 3 d after operation and chest tube was removed 4 d after operation as a routine, and full liquid diet 5 d after operation. RESULTS： Among 114 patients （84 men and 30 women）, 26 patients underwent fast track surgery, including 17 patients over 65 years old and 9 under 65 （P = 0.014）; 18 patients who had preoperative complications could not bear fast track surgery （P 〈 0.001）. No significant differences in tolerance of fast track surgery were attributed to differences in gender, differentiated degree or stage of tumor, pathological type of tumor, or operative incision. The median length of hospital stay was 7 d （5-28 d）, 4% patients were readmitted to hospital within 30 d of discharge. Three patients died and postoperative mortality was 2.6%. All 3 patients had no determinacy to fast track surgery approach.CONCLUSION： The majority of patients with esophageal carcinoma can tolerate fast track surgery. Patients younger than 65 or who have no preoperative diseases have the best results. Median length of hospital stay has been reduced to 7 d.

A multiple template approach for robust tracking of fast motion target

Target tracking is very important in computer vision and related areas. It is usually difficult to accurately track fast motion target with appearance variations. Sometimes the tracking algorithms fail for heavy appearance variations. A multiple template method to track fast motion target with appearance changes is presented under the framework of appearance model with Kalman filter. Firstly, we construct a multiple template appearance model, which includes both the original template and templates affinely transformed from original one. Generally speaking, appearance variations of fast motion target can be covered by affine transformation. Therefore, the affine tr templates match the target of appearance variations better than conventional models. Secondly, we present an improved Kalman filter for approx- imate estimating the motion trail of the target and a modified similarity evaluation function for exact matching. The estimation approach can reduce time complexity of the algorithm and keep accuracy in the meantime. Thirdly, we propose an adaptive scheme for updating template set to alleviate the drift problem. The scheme considers the following differences： the weight differences in two successive frames; different types of affine transformation applied to templates. Finally, experiments demonstrate that the proposed algorithm is robust to appearance varia- tion of fast motion target and achieves real-time performance on middle/low-range computing platform.

Impact of centralization of pancreaticoduodenectomy coupled with fast track recovery protocol:a comparative study from India

BACKGROUND: Fast track strategy in the management of patients undergoing intra-abdominal surgery of various types has emerged as a landmark approach to reduce surgical stress and accelerate recovery. 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.

Study of the retina algorithm on FPGA for fast tracking

Real-time track reconstruction in high-energy physics experiments at colliders running at high luminosity is very challenging for trigger systems. To perform pattern recognition and track fitting, artificial retina or Hough transformation algorithms have been introduced to the field typically implemented on state-of-the-art field programmable gate array(FPGA) devices. In this paper, we report on two FPGA implementations of the retina algorithm: one using a mixed Floating-Point core and the other using Fixed-Point and Look-Up Table, and detailed measurements of the retina performance are investigated and compared. So far, the retina has mainly been used in a detector configuration comprising parallel planes, and the goal of our work is to study the hardware implementation of the retina algorithm and estimate the possibility of using such a method in a real experiment.

Fast density peak-based clustering algorithm for multiple extended target tracking

The key challenge of the extended target probability hypothesis density (ET-PHD) filter is to reduce the computational complexity by using a subset to approximate the full set of partitions. In this paper, the influence for the tracking results of different partitions is analyzed, and the form of the most informative partition is obtained. Then, a fast density peak-based clustering (FDPC) partitioning algorithm is applied to the measurement set partitioning. Since only one partition of the measurement set is used, the ET-PHD filter based on FDPC partitioning has lower computational complexity than the other ET-PHD filters. As FDPC partitioning is able to remove the spatially close clutter-generated measurements, the ET-PHD filter based on FDPC partitioning has good tracking performance in the scenario with more clutter-generated measurements. The simulation results show that the proposed algorithm can get the most informative partition and obviously reduce computational burden without losing tracking performance. As the number of clutter-generated measurements increased, the ET-PHD filter based on FDPC partitioning has better tracking performance than other ET-PHD filters. The FDPC algorithm will play an important role in the engineering realization of the multiple extended target tracking filter.

Adaptive modified hough transform track initiator forHFSWR tracking of fast and small targets

High frequency surface wave radar (HFSWR) is well proved to have over the horizon (OTH) detection capability to weak aerial targets, such as concealed airplanes or cruise missiles. The most important problem of detection of fast and small targets using HFSWR is earlier warning, i.e. enlargement of detection range oftargets. Therefore, the detection threshold should be decreased as low as possible, but numerous false alarms are brought about at the same time. On this condition, conventional track initiation techniques, which normally require the probability of false alarm to be at the level of 10-6, will initiate enormous false tracks and lead to abnormal operation of tracking system. An adaptive modified hough transform (AMHT) track initiator is proposed accordingly and the relation of detection range to the performance of track initiator is analyzed in this paper. Simulations are performed to confirm the capability of track initiation to fast and small targets in dense clutter by AMHT track initiator. The tolerable probability of false alarm of detector can reach the level of 10 -3 . And it performs better than track initiator based on modified hough transform (MHT).

Fast-track program vs traditional care in surgery for gastric cancer

AIM:To systematically review the evidence for the effectiveness of fast-track program vs traditional care in laparoscopic or open surgery for gastric cancer.METHODS:PubMed,Embase and the Cochrane library databases were electronically searched for published studies between January 1995 and April 2013,and only randomized trials were included.The references of relevant studies were manually searched for further studies that may have been missed.Search terms included"gastric cancer","fast track"and"enhanced recovery".Five outcome variables were considered most suitable for analysis:postoperative hospital stay,medical cost,duration to first flatus,C-reactive protein(CRP)level and complications.Postoperative hospital stay was calculated from the date of operation to the date of discharge.Fixed effects model was used for meta-analysis.RESULTS:Compared with traditional care,fasttrack program could significantly decrease the postoperative hospital stay[weighted mean difference(WMD)=-1.19,95%CI:-1.79--0.60,P=0.0001,fixed model],duration to first flatus(WMD=-6.82,95%CI:-11.51--2.13,P=0.004),medical costs(WMD=-2590,95%CI:-4054--1126,P=0.001),and the level of CRP(WMD=-17.78,95%CI:-32.22--3.35,P=0.0001)in laparoscopic surgery for gastric cancer.In open surgery for gastric cancer,fast-track program could also significantly decrease the postoperative hospital stay(WMD=-1.99,95%CI:-2.09--1.89,P=0.0001),duration to first flatus(WMD=-12.0,95%CI:-18.89--5.11,P=0.001),medical cost(WMD=-3674,95%CI:-5025--2323,P=0.0001),and the level of CRP(WMD=-27.34,95%CI:-35.42--19.26,P=0.0001).Furthermore,fast-track program did not significantly increase the incidence of complication(RR=1.39,95%CI:0.77-2.51,P=0.27,for laparoscopic surgery;and RR=1.52,95%CI:0.90-2.56,P=0.12,for open surgery).CONCLUSION:Our overall results suggested that compared with traditional care,fast-track program could result in shorter postoperative hospital stay,less medical costs,and lower level of CRP,with no more complications occurring in both laparoscopic and open surgery for gastric cancer.

Fast-track program in laparoscopic liver surgery:Theory or fact?

AIM:To analyze our results after the introduction of a fast-track(FT) program after laparoscopic liver surgery in our Hepatobiliarypancreatic Unit.METHODS:All patients(43) undergoing laparoscopic liver surgery between March 2004 and March 2010 were included and divided into two consecutive groups:Control group(CG) from March 2004 until December 2006 with traditional perioperative cares(17 patients) and fast-track group(FTG) from January 2007 until March 2010 with FT program cares(26 patients).Primary endpoint was the influence of the program on the postoperative stay,the amount of re-admissions,morbidity and mortality.Secondarily we considered duration of surgery,use of drains,conversion to open surgery,intensive cares needs and transfusion.RESULTS:Both groups were homogeneous in age and sex.No differences in technique,time of surgery or conversion to open surgery were found,but more malignant diseases were operated in the FTG,and then transfusions were higher in FTG.Readmissions and morbidity were similar in both groups,without mortality.Postoperative stay was similar,with a median of 3 for CG vs 2.5 for FTG.However,the 80.8% of patients from FTG left the hospital within the first 3 d after surgery(58.8% for CG).CONCLUSION:The introduction of a FT program after laparoscopic liver surgery improves the recovery of patients without increasing complications or re-admissions,which leads to a reduction of the stay and costs.

Fast-track surgery could improve postoperative recovery in radical total gastrectomy patients

AIM: To assess the impact of fast-track surgery (FTS) on hospital stay, cost of hospitalization and complications after radical total gastrectomy. METHODS: A randomized, controlled clinical trial was conducted from November 2011 to August 2012 in the Department of Digestive Surgery, Xijing Hospital of Digestive Diseases, the Fourth Military Medical University. A total of 122 gastric cancer patients who met the selection criteria were randomized into FTS and conventional care groups on the first day of hospitalization. All patients received elective standard D2 total gastrectomy. Clinical outcomes, including duration of flatus and defecation, white blood cell count, postoperative pain, duration of postoperative stay, cost of hospitalization and complications were recorded and evaluated.Two specially trained doctors who were blinded to the treatment were in charge of evaluating postoperative outcomes, discharge and follow-up. RESULTS: A total of 119 patients finished the study, including 60 patients in the conventional care group and 59 patients in the FTS group. Two patients were excluded from the FTS group due to withdrawal of consent. One patient was excluded from the conventional care group because of a non-resectable tumor. Compared with the conventional group, FTS shortened the duration of flatus (79.03 ± 20.26 hvs 60.97 ± 24.40 h, P = 0.000) and duration of defecation (93.03 ± 27.95 h vs 68.00 ± 25.42 h, P = 0.000), accelerated the decrease in white blood cell count [P < 0.05 on postoperative day (POD) 3 and 4], alleviated pain in patients after surgery (P < 0.05 on POD 1, 2 and 3), reduced complications (P < 0.05), shortened the duration of postoperative stay (7.10 ± 2.13 dvs 5.68 ± 1.22 d,P = 0.000), reduced the cost of hospitalization (43783.25 ± 8102.36 RMBvs 39597.62 ± 7529.98 RMB,P = 0.005), and promoted recovery of patients. CONCLUSION: FTS could be safely applied in radical total gastrectomy to accelerate clinical recovery of gastric cancer patients.

Trajectory tracking and obstacle avoidance method for robots based on fast terminal sliding mode

For accurate trajectory tracking and obstacle avoidance in finite time of a nonholonomic mobile robot,a trajectory tracking controller based on global fast terminal sliding mode method is proposed,which has the advantages of chattering-free and adjustable convergence time.First of all,the kinematics model of the robot is established in mobile carrier coordinates.Secondly,the global structure including terminal attractor and exponential convergence of the fast terminal sliding mode trajectory tracking controller is proved by Lyapunov stability theory,ensuring that the trajectory and heading angle tracking error converges to a smaller zero range in finite time.Finally,the artificial potential field obstacle avoidance method is introduced to make the robot not only track the reference trajectory strictly,but also avoid the obstacles.The simulation results show that the proposed method can achieve a stable tracking control in finite time for a given reference trajectory.

Fast-track rehabilitation vs conventional care in laparoscopic colorectal resection for colorectal malignancy: A meta-analysis

AIM:To evaluate the fast-track rehabilitation protocol and laparoscopic surgery(LFT)vs conventional care strategies and laparoscopic surgery(LCC).METHODS:Studies and relevant literature comparing the effects of LFT and LCC for colorectal malignancy were identified in MEDLINE,the Cochrane Central Register of Controlled Trials and EMBASE.The complications and re-admission after approximately 1 mo were assessed.RESULTS:Six recent randomized controlled trials(RCTs)were included in this meta-analysis,which related to 655 enrolled patients.These studies demonstrated that compared with LCC,LFT has fewer complications and a similar incidence of re-admission after approximately 1 mo.LFT had a pooled RR of 0.60(95%CI:0.46-0.79,P<0.001)compared with a pooled RR of 0.69(95%CI:0.34-1.40,P>0.5)for LCC.CONCLUSION:LFT for colorectal malignancy is safe and efficacious.Larger prospective RCTs should be conducted to further compare the efficacy and safety of this approach.

Effects of multimodal fast-track surgery on liver transplantation outcomes

BACKGROUND: Fast-track surgery and enhanced recovery after surgery have been applied to many surgical procedures; however, data on fast-track surgery and enhanced recovery after surgery following liver transplantation is limited. This study aimed to conduct a prospective study to determine the effects of fast-track surgery on prognosis after liver transplantation. METHODS: This was a prospective, single-blinded, randomized study. One hundred twenty-eight patients undergoing liver transplantation were selected for the fast-track (FT group, n=54) or conventional process (NFT group, n=74). The primary endpoints were intensive care unit (ICU) stay and hospital stay. The secondary endpoints were as follows: operative time, anhepatic phase time, intraoperative blood loss, intraoperative blood transfusion volume, postoperative complications, readmission rate, and postoperative mortality. RESULTS: There was no significant difference in preoperative demographics between the two groups. The median ICU stay was 2 days (range 1-7 days) in the FT group and 5 days (range 3-12 days) in the NFT group (P<0.01). Furthermore, the hospital stay was also significantly reduced in the FT group (P<0.01). The operative time, anhepatic phase time, intraoperative blood loss, and intraoperative blood transfusion volume were decreased in the FT group compared with the NFT group (P<0.05). Based on Spearman correlation analysis, the ICU stay and hospital stay may be positively correlated with operative time, anhepatic phase time and intraoperative blood loss. There were no differences in the incidence of postoperative complications, readmissions, and postoperative mortality between the two groups. CONCLUSION: Fast-track procedures effectively reduce the ICU stay and hospital stay without adversely affecting prognosis. This study demonstrated that fast-track protocols are safe and feasible in liver transplantation.

Early discharge after major gynaecological surgery: advantages of fast track surgery

Introduction: Fast Track Surgery (FTS) programs have been adopted by many specialties with documented improved patient outcomes and reduced length of stay (LOS). Methods: We initiated a FTS program in January 2008 and present our experience up to and including November 2010 on patients whose LOS was 2 days. Results: During the study period 242 patients had a laparotomy performed. Overall 54(22.3%) patients were discharged on day 2. In the first year of initiating our FTS program 10% were discharged on day 2, 25% in year 2 and 31% in year 3. Twenty-two patients (41%) had malignant pathology and of these, 16 (73%) had local or regional spread and 6 (27%) had distant spread. Forty patients (74%) had vertical midline incisions (VMI) performed. Surgery was classified as complex in 40 cases (74%) and 6 (11%) patients underwent staging lymph node dissection. Average patient BMI was 26.1 with 44% of patients considered overweight or obese. There were no intraoperative complications recorded. When compared to 188 patients whose LOS was greater than 2 days, the early discharge cohort were more likely to have benign pathology, more likely to be younger, to have a transverse incision, to have received COX II inhibitors, to have a lower net haemoglobin (Hb) change and to tolerate early oral feeding. Conclusions: Increased clinical experience with FTS enables over 31% patients undergoing laparotomy to be safely discharged on day 2 without an increase in the read-mission rate or morbidity.

A 5-Year Review of Gynaecological Oncology Patients Managed by a Fast Track Surgery Program

Introduction: The aim of this study is to provide a comprehensive 5-year audit of patients undergoing laparotomy for suspected or confirmed gynaecological malignancy to document the frequency and incidence of adverse events and to investigate factors associated with shorter length of stay and readmission to hospital. Methods: A 5-year surgical audit of the period commencing 2008 and concluding 2012. All patients undergoing laparotomy were included in the audit without exclusions. Approval was granted by the local Ethics Review Committee. Results: Four hundred and twenty-seven patients underwent laparotomy for suspected or confirmed gynaecological malignancy and were managed by Fast Track Surgery (FTS) principles. Average age was 54.8 years and average weight and BMI were 73.4 kg and 28.1 respectively. Ultimately 254 (59%) patients had confirmed malignancy. Average surgery duration was 2.36 hours and average estimated blood loss (EBL) at surgery was 262 mL. Median and mean LOS was 3.0 and 3.5 days respectively with 125 (29%) patients discharged on day 2. Overall transfusion rate was 5%. Other adverse events in decreasing frequency were hospital readmission (3.7%), significant wound infection (3%) and unplanned High Dependency Unit (HDU) admission (1.4%). All other adverse events were uncommon with rates <0.5%. Factors associated with a short LOS included year of surgery, age, performance status, malignant vs benign pathology, the use of COX-2 inhibitors, operation time, incision type, transfusion, and radical hysterectomy, at least 1 complication, if patients tolerated early oral feeding (EOF). In multivariable analysis, year, age, performance status, the use of COX-2 inhibitors, operation time and incision type were significant. Factors associated with readmission included the use of COX-2 inhibitors, operation time, performance of a lymph node dissection, return to operating theatre, operation category at least 1 complication, and in multivariable analysis lymph node dissection and the occurrence of at least 1 complication were significant. Conclusions: This 5-year audit is important in establishing a contemporary incidence and the prevalence rate of serious adverse events for patients with suspected or confirmed gynaecological cancer undergoing laparotomy and managed by FTS principles. The community can be reassured that the incidence of serious adverse events is low when managed by FTS principles.
