ABSTRACT
Objective:To design a tracheotomy cannula cuff filling device for hyperbaric oxygen therapy, which is convenient for clinical operation, improves work efficiency and reduces the incidence of aspiration pneumonia.Methods:This study was a randomized controlled trial. From July 2020 to June 2022, 90 patients with tracheotomy who were treated with hyperbaric oxygen in the First Hospital of Jiaxing were selected as the research objects. According to the random number table method, the patients were divided into the experimental group and the control group, with 45 cases in each group. In the experimental group, the cuff pressure was maintained by the tracheotomy cannula cuff filling device, and in the control group, the traditional water injection method was used to maintain the cuff pressure. The operation time, infection index and incidence of aspiration pneumonia were compared between the two groups.Results:The operation time in the experimental group was (6.33 ± 1.31) s lower than that in the control group (40.96 ± 3.70) s, and the difference was statistically significant ( t=-59.11, P<0.05). Body temperature, C-reactive protein and procalcitonin after treatment in the experimental group were (36.91 ± 0.83) ℃, (34.59 ± 16.25) mg/L, (1.57 ± 0.82) μg/L, respectively, lower than those in the control group (37.42 ± 0.72) ℃, (44.18 ± 18.10) mg/L, (2.45 ± 0.92) μg/L, the differences were statistically significant ( t=-3.09, -2.64, -4.73, all P<0.05). The difference of white blood cell count post-treatment between the two groups was not statistically significant ( P>0.05). The incidence of aspiration pneumonia in the experimental group was 11.11%(5/45) lower than 31.11%(14/45) in the control group, and the difference was statistically significant ( χ2=5.17, P<0.05). Conclusions:The application of tracheotomy cannula cuff filling device can simplify the operation process, reduce the incidence of infection and aspiration pneumonia, and optimize the clinical work.
ABSTRACT
Objective To summarize the effect and safety of paclitaxel drug-coated balloon in the treatment of patients with coronary in-stent restenosis.Methods From August 2015 to July 2018,30 patients with in-stent restenosis in Jinqiu Hospital of Liaoning Province were selected and they had undertook the percutaneous transluminal coronary angioplasty(PTCA) with paclitaxel drug-coated balloon under intravascular ultrasound-guided.Results Intravascular ultrasound was done after PTCA with ordinary balloon before the paclitaxel drug - coated balloon angioplasty.The drug-coated balloon expansion continued to 30s-60s[(43 ± 11)s] in all in-stent restenosis,and the success rate of immediate intervention operation was 100%.The lesion degree of stenosis and lesions minimum diameter at postoperation and preoperation had statistically significant differences[(10.67 ± 5.53)% vs.(79.67 ± 9.28)% ,t= -33.797,P<0.01;(2.80 ± 0.44)mm vs.(0.64 ± 0.31)mm,t=22.039,P<0.01].There was one 89-year-old patient died because of respiratory failure from pneumonia,and two patients with angina pectoris after operation got relieve after one week drug treatment. There were no other adverse cardiovascular events during the duration of hospital stay after the intervention operation.Conclusion Paclitaxel drug-coated balloon is effective and safe in the treatment of patients with coronary in - stent restenosis lesions. It is one new method named " the intervention without once again permanent implant " that the paclitaxel drug - coated balloon expands under intravascular ultrasound-guided,but the long-term effect is uncertain yet.
ABSTRACT
Objective To investigate the effect of high altitude aviation on the pressure and diameter of the trachea cannula cuff after injecting air or water. Methods In the circumstance 5 km height and 795 hPa cabin pressure, the air injected cuffs were divided into two groups, one was under the ground circumstance, the other was in the high altitude aviation environment. The volumes of injected air were 5 ml, 7 ml, 9 ml, 11 ml, 13 ml, 15 ml, 17 ml, and the cuff pressure and its diameter were measured. The water injected cuffs were also divided into two groups of ground and high altitude aviation environment. The volumes of injected water were 10 ml, 12 ml, 14 ml, 15 ml, 16 ml, and the cuff pressure and its diameter were measured. The results were compared between the ground circumstance and high altitude aviation environment. Results The diameter of injection air group versus under the ground circumstance group had the statistical significance (t=5.000-9.449, P0.05), while different air volume injection had significant effect on pressure and diameter (F=5.132, 5.980, P<0.01). When the water volume was 10 ml, the cuff pressure was (24.00±4.62) cmH2O (1 cmH2O=0.098 kPa) , which was appropriate to the range of cuff pressure (20-30 cmH2O). Conclusions In high altitude aviation environment the trachea cannula cuff should adopt water injection, and the best water volume is about 10 ml.
ABSTRACT
Objective To evaluate the efficacy and safety of labor induction by the double balloon device in women with preeclampsia and eclampsia.Methods Labor induction was carried out in 37 women with preeclampsia and eclampsia from July 2011 to November 2012.All the labor inductions were performed using the double balloon device.Results The cervical Bishop scores of 37 cases of patients with preeclampsia and eclampsia were significantly lower before using double balloon device [(3.38 ± 0.50) scores] compared with after using double balloon device [(6.44 ± 0.63) scores] with a statistically significant difference (t =23.54,P ＜0.01).Blood pressure had no obvious change before and after using double balloon device [SBP(158.38 ± 13.89)mmHg vs (162.48 ± 12.56)mmHg,P ＞ 0.05,and SDP(112.71± 15.53) mmHg vs (108.19 ± 8.37) mmHg,P ＞ 0.05].The rate of vaginal delivery was 89.2％ (33/37),and the total hours of labor were (5.8 ± 0.63) h.Compared with selective cesarean section,vaginal delivery after double balloon to promote cervical mature had less blood loss (t =9.19,P ＜0.01),quicker postpartum recovery,shorter hospitalization time (t =11.18,P ＜ 0.01),lower birth body mass (t =2.96,P ＜0.01) and higher scores of 1 minutes Apgar score (t =2.34,P ＜0.05).Conclusions The double balloon device appeared to be a safe and effective method to induce labor in women with preeclampsia and eclampsia.Wide scale studies and further use of the device for labor induction in women with preeclampsia and eclampsia were warranted.
ABSTRACT
Objective To explore the endoscopic managements for biliary and pancreatic diseases in patients with the history of complex gastrointestinal surgery.Methods Data of four patients who underwent balloon-assisted enteroscopy after complex digestive surgeries (2 patients underwent Roux-en-Y reconstruction,2 others Whipple reconstruction) were retrospectively collected.One patient with bilio-intestinal anastomosis was explored by double-balloon enteroscope (DBE),and balloon-assisted enteroscopy combined with ERCP was used for other 3 patients.Results Therapeutic ERCP was successfully performed on one patient,and the diagnosis of 3 others were confirmed.No operation-related complications such as bleeding or perforation was observed.Conclusion Balloon-assisted enteroscopy combined with ERCP is an important diagnostic and therapeutic method for biliary and pancreatic diseases in the patients after complex gastrointestinal surgery.
