ABSTRACT
Objective:To evaluate the feasiblity and safety of in situ fenestration during the endograft of thoracic endovascular aortic repair (TEVAR) via the left subclavian artery (LSA).Methods:A total of 23 patients, including 17 patients with thoracic aortic dissection and 6 patients with thoracic aortic aneurysm, were respectively enrolled from October 2018 to June 2019 at Nanfang Hospital, Southern Medical University. All of the patients underwent in situ fenestration of LSA via the thoracic artery endograft following the TEVAR procedure. A 21 G preflex hollow needle was used to puncture the endograft from the medial segment of LSA for in situ feneatration. The success rate, clinical effect and complications were recorded on 1, 3 and 6 months after in situ fenestration.Results:The success rate was 100% in all the 23 patients with needle puncture in situ fenestration of LSA. The rechecked thoracic aorta angiography showed that both thoracic aortic main endograft and the LSA branch cover stent were well expanded, and there were no endoleaks occurred around the LSA branch cover stent. No hematoma was found in the supraclacicular fossa within all the perioperative period. A small pneumatothorax in the left pleural cavity which did not need treatment was being detected in 1 patient on the chest film 3 days after the procedure. The mean follow-uptime was (4.2±1.4) months. There were no retrograde tearing happened in the proximal end of the endograft, and no endoleak happened around the LSA branch cover stent either.Conclusion:The technique of needle puncture fenestration of LSA via the thoracic artery endograft is considered as a simple, safe, and effective method of in situ LSA reconstruction.

ABSTRACT
Objective To observe the effect and safety of the endovascular hypothermia through hypothermic intravenous infusion device in the treatment of patients with severe craniocerebral injury compared with conventional surface cooling. Methods A total of 66 cases of patients with severe cranio-cerebral injury were randomly divided into the observation group and the control group with 33 cases in each group according to envelop randomization. The control group received surface cooling, and the observation group was given surface cooling plus endovascular hypothermia through hypothermic intravenous infusion device. The target temperature was 35 ℃maintained for 3-5 days, and natural rewarming was applied at the speed of 0.1-0.5℃/h to 36.0-37.3℃. The time to reach target temperature, the constant stability, the incidence rate and severity of complication such as shiver, arrhythmia, skin injury and agitation were recorded and compared between two groups, as well as the heart rate, breathing rate, pulse rate, blood pressure and Glasgow Coma Scale (GCS) scores after 72 h of treatment. Glasgow Outcome Scale scores 30 days after treatment and nursing workload were also calculated and compared. Results The cooling speed, time to reach target temperature and the ability to maintain at 35℃were (1.3±0.2)℃/h, (2.3±0.2) h and (6.5± 1.8)%in the observation group, respectively, compared with (0.5±0.1)℃/h, (3.6±0.6) h and (11.3±2.2)%in the control group, which had significant differences (t=1.862, 2.112, 2.408,P < 0.05). The occurrence rates of shiver, arrhythmia, skin damage and dysphoria and restlessness in the observation group were 33.33%(11/33), 9.09%(3/33), 6.06%(2/33) and 27.27%(9/33), respectively, which were much lower than those in the control group 84.85%(28/33), 15.15%(5/33), 33.33%(11/33), 54.55%(18/33),χ2=1.764-2.733,P<0.05. The heart rate, breathing rate, pulse rate, systolic blood pressure and GCS score after 72 h of treatment were(68.31 ± 3.73)times/min,(16.60 ± 1.52)times/min,(136.35 ± 3.71)mmHg(1 mmHg=0.133 kPa),(34.61 ± 1.05)℃, (9.91±4.05)points in the observation group, while(58.31±3.62)times/min,(19.81±1.83)times/min,(150.66± 2.70)mmHg,(35.65 ± 1.36)℃,(7.63 ± 3.17)points in the control group, and there were significant differences between two groups(t=2.275-3.035, P < 0.05).Besides, the ice-changing ice and turning-over time in the observation group were both remarkably reduced compared with control group, (14.03±3.11) min/h vs (38.12± 2.70) min/h (t=3.356, P<0.05) , (15.08±3.07) min/h vs (26.16±2.54) min/h ( t=3.021, P<0.05). Patients with good recovery, mild disability, severe disability, death in the observation group were 16, 13, 3 and 1 case, while 6, 11, 9, 7 cases in the control group (χ2=2.351,P < 0.05). Conclusions The endovascular hypothermia through hypothermic intravenous infusion device can rapidly reduce and effectively maintain target temperature, reduce the incidence rate of complication, improve the vital signs and decrease the nursing workload in order to improve neurological outcome in the treatment of patients with severe craniocerebral injury.

ABSTRACT
Objective To study effect of Xuebijing injection on coagulation function and prevention of deep venous thrombosis in elderly fracture patients with mechanical ventilation.Methods 60 patients were randomly divided into control group(30 cases) and Xuebijing group(30 cases).Xuebijing group received Xuebijing injection, besides physical therapy for prevention of deep venous thrombosis received by control group.Coagulation parameters and Lac at different time points,thrombosis incidence,hemorrhage incidence APACHE II score and 28 -day mortality were compared between the two groups.Results In Xuebijing group,PT,APTT,DD on d3 and Fg 48 on d5 had statistically significant differences compared with before treatment.PT,APTT on d3,d5 and DD on d5 were statistical-ly different compared with the control group(P <0.05).PLT,Lac,hemorrhage incidence and 28 -day mortality had no significant differences between the two groups.Thrombosis incidence in Xuebijing group was significantly lower than the control group(20.00% vs 3.33%) (χ2 =4.043,P =0.044,P <0.05).Both of APACHE II score were lower than before treatment,but the Xuebijing group was significantly decreased(t =5.48,P =0.000,P <0.05). Conclusion Xuebijing injection could improve coagulation function,and decrease thrombosis incidence in elderly fracture patients with mechanical ventilation.
ABSTRACT
Objective To study the therapeutic effect of Xuebijing injection in severe craniocerebral injury patients with coagulation disturbance.Methods Sixty-five patients were randomly divided into Xuebijing treatment group (n=35) and control group (n=30).They all received regular treatment,while Xuebijing treatment group received Xuebijing injection additionally (0.9% sodium chloride injection 100 mL adding 30 mL Xuebijing twice daily for a consecutive 10 d).Prothrombin time (PT),active partial thromboplastin time (APTT),levels of blood platelet (PLT),d-dimer (DD),tumor necrosis factor α (TNF-α),interldeukin (IL)-6 and IL-8,and Glasgow coma scale (GCS) scores at different time points,progressive intracranial hemorrhage (PIH) rate within 72 h,survival rate of 28 d were compared between two groups.Results Coagulation in all patients after treatment was significantly improved as compared with that before treatment (P<0.05).At 72 h after treatment,the PT,APTT,and levels of DD and PLT in Xuebijing treatment group were significantly improved as compared with those in the control group (P<0.05);levels ofTNF-α,IL-6 and IL-8 at 72 h after treatment in the treatment group ([1.41±0.32] ng/L,[80.4±25.1] ng/L and [5.17±0.59] ng/L) were significantly lower than those in the control group ([1.74±0.30] ng/L,[96.6±23.4] ng/L and [8.32±0.72] ng/L],P<0.05).The PIH rate within 72 h in the treatment group (31.4%) was significantly lower than that in the control group (46.7%,P<0.05).Conclusion Xuebijing injection could improve the abnormal coagulation and lower the PIH rate in severe craniocerebral injury patients with coagulation disturbance,possibly because Xuebijing injection could ameliorate inflammation.
ABSTRACT
Objective To study the effect of Xuebijing injection on transfusion and systemic inflammation in traumatic coagulopathy patients. Methods Seventy-nine patients were randomly divided into Xuebijing Group (36 cases) and Control Group (43 cases). Xuebijing group received Xuebijing injection in addition to the regular treatment received by control group. Levels of TNF-α, IL-6, IL-8 and transfusion amount between two groups were compared. Results Coagulation abnormality was almost corrected in all patients after treatment. In Xuebijing Group, transfusion of RBC, FFP and cryoprecipitate were significantly less than that in control group (P<0.05). At 72 h after admission, TNFα, IL-6 and IL-8 were significantly lower in Xuebijing Group (P < 0.05). Conclusion Xuebijing injection could reduce transfusion in traumatic coagulopathy patients , possibly resulting from its antagonism against systemic inflammation.
ABSTRACT
Objective To discuss the clinical application of homemade airway exchange catheter on the extubation of patients with difficult tracheal intubation in intensive care unit(ICU). Methods Sixty-two patients with difficult tracheal intubation who failed their initial extubation trial were randomly divided into conventional group (31 cases)and observation group(31 cases). The patients in the conventional group received routine extubation process,while the patients in the observation group were extubated under the guidance over a homemade airway exchange catheter. The changes in heart rate(HR),blood pressure,respiratory rate(RR)and pulse blood oxygen saturation(SpO2)were compared at 12 hours after extubation,so as the re-intubation rate,intubation success rate at first attempt and re-intubation time in two groups,and the tolerance and complications after extubation were observed. Results After extubation,the HR,blood pressure and RR were increased significantly(all P<0.05), and the SpO2 was much lower in conventional group(P<0.05),while those parameters were changed little and basically in the normal ranges in the observation group. At 12 hours after extubation,the re-intubation rate was much lower(6.45%vs. 25.81%,P<0.05)in the observation group,with shorter re-intubation time(seconds:27±14 vs. 49±28,P<0.01),higher intubation success rate at first attempt(90.32%vs. 54.84%,P<0.01)and better tolerance (77.4% vs. 61.3%,P<0.05)compared with those in the conventional group. There was no severe complication in the observation group,and there were 1 cases of glottic edema with cricothyroid membrane puncture,2 cases of broncheal mucous membrane bleeding and 2 cases of bucking in the conventional group. Conclusion Compared with conventional extubation process,the extubation over homemade airway exchange catheter can increase the rate of extubation,reduce re-intubation rate and the re-intubation time,with favorable tolerance and no occurrence of serious complications,and is one of the safe and effective extubation strategies in patients with difficult tracheal intubation in ICU.
ABSTRACT
Objective To approach the protective effect of dexmedetomidine on mechanically ventilated patients with pulmonary contusion. Methods A prospective randomly controlled trial was conducted. 70 mechanically ventilated patients with pulmonary contusion from January 2010 to December 2012 in the Critical Care Medicine of Foshan Hospital of Traditional Chinese Medicine were divided into a control group and a therapy group by the difference in number odd or even,with 35 patients in each group. Based on the same principles of comprehensive treatment,the control group used midazolam,and the therapy group used dexmedetomidine for sedation. The measured parameters included oxygenation index(PaO2/FiO2),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6), and extra-vacular lung water index(EVLWI)for both groups on the1st and 5th day. The incidence of delirium,the time of mechanical ventilation,and the incidence of hypotension were observed in both groups. Results Compared with those on the 1st day,TNF-α,IL-6 and EVLWI on the 5th day were decreased significantly in both groups〔the control group TNF-α(ng/L):1.29±0.38 vs. 2.21±0.37,IL-6(ng/L):97.97±28.77 vs. 131.03±41.52,EVLWI (mL/kg):8.25±2.03 vs. 11.96±3.36;the therapy group TNF-α:1.06±0.33 vs. 2.32±0.37,IL-6:82.07±23.35 vs. 134.98±64.25, EVLWI(mL/kg):6.74±1.33 vs. 11.23±2.78, all P0.05). Conclusion Dexmedetomidine has protective effect on mechanically ventilated patients with pulmonary contusion, and it is an relatively ideal sedative drug for these patients.

ABSTRACT
Objective To approach the clinical effect of cefoperazone sulbactam associated with tigecycline for treatment of patients with severe pulmonary infection caused by pan drug-resistant Acinetobacter baumannii in intensive care unit(ICU). Methods Retrospectively,the treatments of 88 patients with sepsis and pulmonary infection caused by pan drug-resistant Acinetobacter baumannii admitted in ICU from January,2011 to June,2013 were analyzed,among them antibiotics were used for 82 patients,and the rest 6 patients did not use antibiotics because of family refusal or abandonment of therapy. The patients having used antibiotics were divided into three groups:A group(27 patients)received cefoperazone sulbactam,B group(30 patients)received cefoperazone sulbactam associated with amikacin,and C group(25 patients)received cefoperazone sulbactam associated with tigecycline, antimicrobial treatment being for 7-15 days. The venous blood was collected to determine the changes in white blood cell count(WBC),C-reactive protein(CRP)and procalcitonin(PCT)before and after therapy. The rate of bacteriological efficiency,successful weaning of mechanical instrument,28-day mortality rate and clinical efficacy were observed after therapy in three groups. Results Before therapy,the comparisons of levels of WBC,CRP and PCT among three groups were of no statistically significant difference(all P>0.05),and they were decreased obviously after therapy in three groups among which they were decreased most significantly in C group〔WBC(×109/L):17.01±5.35 vs. 20.40±6.54,18.28±6.41;CRP(mg/L):64.6±8.4 vs. 68.3±12.7,70.0±13.4;PCT(μg/L):20.84±7.26 vs. 36.14±10.12,52.66±13.47,P<0.05〕. The rates of bacteriological efficiency and successful weaning in C group were increased more significantly than those in either A or B groups after therapy(bacteriological efficiency:76.00%vs. 44.44%,46.67%,χ2=9.750,P=0.006;rate of successful weaning:72.00%vs. 40.74%, 43.33%,χ2=12.083,P=0.009),and 28-day mortality rate in C group was much lower than those in A and B groups (24.00% vs. 48.15%,36.67%,χ2=11.510,P=0.030). The total clinical efficiency in C group was much higher than those in A and B groups(76.00%vs. 44.44%,46.67%,both P<0.05). Conclusion Cefoperazone sulbactam associated with tigecycline has significant clinical therapeutic effect in patients with pulmonary infection caused by pan drug-resistant Acinetobacter baumannii in ICU,as it can decrease inflammatory reaction,increase the rates of successful weaning and survival.
