Abstract： Objective To analyze clinical outcomes of interventional therapy for common congenital heart diseases （CHD）. Methods We retrospectively analyzed the clinical records of 57 patients with CHD who underwent catheter interventional therapy in People’s Hospital of Deyang City between March 2009 and January 2012. There were 31 male patients and 26 female patients with their mean age of 29.4±3.5 years（ranging from 1.5 to 75.0 years）. There were 21 patients with patent ductus arteriosus （PDA）, 12 patients with ventricular septal defect （VSD）, and 20 patients with atrial septal defect（ASD）；and 2 patients with VSD plus ASD, 1 patient with VSD plus PDA, and 1 patient with ASD plus PDA. Occluder and supplying system made in China were used in the interventional therapy. For the patients with ASD plus PDA, PDA was blocked before ASD；for the patients with VSD plus PDA, PDA was blocked before VSD；and for the patients with VSD plus ASD, VSD was blocked before ASD. Results The duration of interventional therapy ranged from 30 to 90 minutes. The success rate of operation was 98.3%（56/57）. Operation was given up in an old female patient with ASD and chronic obstructive pulmonary disease because of pulmonary hypertension. The hospital stay was 3 -7 days. All the patients were followed up at the outpatient department for 1 month to 2 years by color Doppler echocardiogram, chest X-ray and electrocardiograph, and no complication occurred during follow-up. Conclusion With complete understanding of surgical indications and strict compliance with procedures, catheter interventional therapy is safe, minimal invasive, and effective in CHD treatment.
ObjectiveTo explore the effect of catheter directed thrombolysis (CDT) in treatment of acute deep venous thrombosis (ADVT) in lower extremity. MethodsLimb circumference at 15 cm above and below the knee at affected side, as well as patency improvement score of 46 patients with ADVT in lower extremity, who received treatment in The Rocket Army General Hospital of PLA between January 2014 and October 2015, were colleted retrospectively, to analyze the effect of CDT in treatment of ADVT in lower extremity. ResultsAll patients were placed catheter successfully, 5 patients were placed catheter by 'contralateral mountain' technique retrograde, 40 patients were placed catheter through the limb popliteal vein at affected side anterograde, guiding by ultrasound, 1 patient was placed catheter through femoral vein at affected side. All of 46 patients got successful thrombolysis, and thrombolysis time was (4.7±1.8) d (3-12 d). There were 8 patients suffered from complications in different situation, and got treatment of drug withdrawal or tube drawing all ease, no one died. Compared with before CDT treatment in same group, the limb circumference at 15 cm above (P=0.028, P=0.017, P=0.031) and below (P=0.035, P=0.038, P=0.047) the knee at affected side, and patency improvement score (P=0.023, P=0.028, P=0.031) in all patients group, 22-45 years group, and 46-74 years group were all lower after CDT treatment. The limb circumference at 15 cm above (P=0.073, P=0.387, P=0.358) and below (P=0.416, P=0.625, P=0.253) the knee at affected side after CDT treatment were not differed with corresponding indexes of healthy side in the same group of all patients group, 22-45 years group, and 46-74 years group. Ultrasound after treatment showed that, blood vessel recanalization occurred in 15 patients (32.6%), partial blood vessel recanalization occurred in 28 patients (60.9%), but thrombus of 3 patients (6.5%) didn't removed, the total effective rate was 93.5% (43/46). Forty three patients were followed up for 1-24 months, the median is 18-month. During follow-up period, skin color obviously deepened after the activity occurred in 5 patients, obvious limb acid bilges occurred in 19 patients, vein thrombosis (DVT) recurred in 9 patients of 28 patients with partial blood vessel recanalization, in addition, thrombosis syndrome (PTS) occurred in 11 patients. ConclusionCDT is the most direct and effective way to treat ADVT.
ObjectiveTo analyze the related risk factors for catheter-associated urinary tract infection in the Intensive Care Unit (ICU), and make corresponding nursing countermeasures. MethodsBy target monitoring of catheter-associated urinary tract infection in 184 patients in the ICU from 2011 to 2012, infection risk factors were analyzed. The measures of nursing interventions had been taken since January 2012, and the effects before and after the intervention were contrasted and evaluated. ResultsBefore the intervention, 951 out of 1 229 patients in 2011 had indwelling catheter, and catheter-associated urinary tract infection occurred in 127 patients with an infection rate of 13.35%. After the intervention, 841 out of 1 437 in 2012 had indwelling catheter, and catheter-associated urinary tract infection occurred in 57 patients with an infection rate of 6.78%. ConclusionTaking effective intervention measures can effectively reduce the ICU catheter-associated urinary tract infection and it also ensures the safety of medical care.
ObjectiveTo reduce the incidence of peritoneal dialysis (PD) catheter complications through a continuous quality improvement (CQI) process. MethodsTwenty-nine patients with catheters inserted (from January 2011 to March 2011) before CQI, and another 41 patients with catheters inserted (between April 2011 and January 2012) after CQI were observed and analyzed. The possible causes of complications of catheter were summarized, and then on the basis of that, a PDCA four-step (plan-do-check-act) method was designed with a view to reducing the incidence of postoperative complications. ResultsPD catheter dysfunction decreased from 6.90% to 2.44%. The incidence of leakage decreased from 44.83% to 9.76%. ConclusionCQI is a useful method to reduce the incidence of postoperative complications of PD catheter in peritoneal dialysis.
In existing vascular interventional surgical robots, it is difficult to accurately detect the delivery force of the catheter/guidewire at the slave side. Aiming to solve this problem, a real-time force detection system was designed for vascular interventional surgical (VIS) robots based on catheter push force. Firstly, the transfer process of catheter operating forces in the slave end of the interventional robot was analyzed and modeled, and the design principle of the catheter operating force detection system was obtained. Secondly, based on the principle of stress and strain, a torque sensor was designed and integrated into the internal transmission shaft of the slave end of the interventional robot, and a data acquisition and processing system was established. Thirdly, an ATI high-precision torque sensor was used to build the experimental platform, and the designed sensor was tested and calibrated. Finally, sensor test experiments under ideal static/dynamic conditions and simulated catheter delivery tests based on actual human computed tomography (CT) data and vascular model were carried out. The results showed that the average relative detection error of the designed sensor system was 1.26% under ideal static conditions and 1.38% under ideal dynamic stability conditions. The system can detect on-line catheter operation force at high precision, which is of great significance towards improving patient safety in interventional robotic surgery.
Objective To understand the urination of orthopedic patients after the catheter is removed, and to explore the influencing factors of urodynia. Methods Convenient sampling was used to select 160 patients who underwent surgical treatment in the Department of Orthopedics of West China Hospital of Sichuan University from May to July 2020. Questionnaires were used to investigate the patients’ urination, and a logistic regression model was used to analyze the factors affecting the patients’ urodynia. Results A total of 157 patients urinated by themselves after the catheter was removed, with 102 cases of dysuria. Logistic regression results showed that male [odds ratio (OR)=0.282, 95% confidence interval (CI) (0.092, 0.863), P=0.027], Huaxi Emotional-Distress Index score [OR=1.407, 95%CI (1.124, 1.760), P=0.003] and intraoperative fluid infusion [OR=1.001, 95%CI (1.000, 1.002), P=0.014] were the influencing factors of urodynia. Conclusion Most orthopedic patients can urinate on their own after the catheter is removed, but more than half of the patients experience urodynia during the first urination. Gender, mental status and intraoperative fluid infusion are the influencing factors of urodynia after urinary catheter removal after surgery. Clinical nursing staff should identify these influencing factors as soon as possible and carry out targeted interventions to improve the success rate of patients with urination after removing the catheter, reduce the incidence of urodynia, and promote the recovery of patients.
ObjectiveTo investigate the incidence of nosocomial infection and device-related infection in the Intensive Care Unit (ICU), analyze its related risk factors, and search for effective measures to prevent and control nosocomial infection. MethodsBy prospective objective monitoring method, we surveyed 294 patients hospitalized in the ICU for at least 48 hours between January and December 2012. The doctor in charge filled in relevant information of the patients to complete the questionnaires, and hospital infection management staff was responsible for tracking, judging, and statistical analysis. ResultsIn the 294 patients, 61 had hospital infections, and there were 78 cases. The hospital infection rate was 20.75%, and the case infection rate was 26.53%. The day incidence of patient infection was 16.01‰, and day infection rate was 20.47‰ for infection cases. After average severity of illness score adjustment, the day case infection rate was 7.48%, ventilator associated pneumonia (VAP) infection rate was 27.27‰, central venous catheter associated bloodstream infection rate was 6.58‰, and catheter associated urinary tract infection rate was 3.15‰. ConclusionICU has a high risk of hospital infection. In the device related infections, VAP infection rate is the highest. Continuous improvement can be achieved through monitoring and discovering problems, strengthening hospital infection management training for the medical personnel of the hospital, close communication between doctors and hospital infection management staff, and strict implementation of hospital infection management measures.
Objective To find the most effective treatment for a patient with difficult selective biliary cannulation (DSBC) during endoscopic retrograde cholangiopancreatography (ERCP) by EBM practice. Methods Evidence was retrieved from The Cochrane Library (Issue 1, 2010), ACP online, NGC (1998 to June 2010), PubMed (1950 to June 2010), and CBM (1994 to June 2010). The collected evidence was then graded. Results After preliminary research, we identified 18 relevant articles. The evidence showed that pre-cutting technique could increase cannulation success rates in DSBC and was safe, effective, and time-saving for an experienced endoscopist. Pancreatic duct occupation was easier to perform than pre-cutting technique and could also increase selective cannulation success rates in DSBC. According to the evidence, together with endoscopist’s experience and the preference of the patient and his family, needle-knife precut papillotomy was performed. Successful selective biliary cannulation was accomplished after pre-cutting. Conclusion The current evidence suggests that pre-cutting technique and pancreatic duct occupation could increase selective cannulation success rates in DSBC. Patients’ condition and endoscopist’s experience should be considered properly before the operation.
ObjectiveTo investigate the therapeutic evaluation of catheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular in the treatment of lower extremity atherosclerotic occlusive disease (ASO). MethodsClinical data of 64 ASO patients who were treated in our hospital from June 2011 to October 2014 were analyzed retrospectively. These patients were divided into two groups according to the therapies:33 patients were treated by catheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular (combination group), and the other 31 patients were only treated by multiple minimally invasive techniques of endovascular (intervention group). Comparison of the clinical indexes was performed between the 2 groups, including vascular patency rate, stent implantation rate, operation time, ankle-brachial index (ABI), saturation of blood oxygen (SO2) of toes, temperature of foot skin, amputation rate, and hospitalization expense. ResultsIn the same group (combination group and intervention group), compared with the time point of before operation, the clinical indexes of the ABI, SO2 of toes, and temperature of foot skin were higher after operation (P<0.05). At the same time point of before or after operation, there were no significant difference between the 2 groups in ABI, SO2 of toes, and temperature of foot skin (P>0.05). The vascular patency rate of combination group was higher than that of intervention group[97.0% (32/33) vs. 83.9% (26/31)], P<0.05. But the stent implantation rate[18.2% (6/33) vs. 64.5% (20/31)], amputation rate[3.0% (1/33) vs. 16.1% (5/31)], operative time[(2.0±0.5) h vs. (4.0±1.1) h], and hospitalization expense of patients who got successful limb salvage[(8 500±1 200) yuan vs. (34 000±2 100) yuan] of combination group were all lower or shorter than those of intervention group (P<0.05). After operation, there were no complication happened in the patients who got successful limb salvage of combination group (n=32) and intervention group (n=26). In postoperative 6 months, the lower extremity arteries in patients who got successful limb salvage of combination group and intervention group were all examined by color ultrasonography, and they were unblocked. The lower extremity arteries of the patients with stent implantation in the 2 groups suffered with no obvious stenosis or occlusion. ConclusionsCatheter-directed thrombolysis combined with multiple minimally invasive techniques of endovascular can become one of the surgical treatment methods for ASO, which characterized by minimally invasive operation, effective treatment, and low cost.
Objective To discuss the effect of monitoring-training-planning (MTP) intervention model on the prevention and control of catheter–associated urinary tract infection (CAUTI) in Intensive Care Unit (ICU). Methods Patients with indwelling catheter from departments with ICU (ICU, ICU of the Department of Neurosurgery, ICU of the Department of Neurologic Medicine) between 2014 and 2015 were included in this study. Based on the inclusion criteria, target monitoring indicators were set in accordance with Hospital Infection Monitoring Norms. A total of 493 patients with indwelling catheters from January to December 2014 were subjected to target surveillance, and were used as baseline for the study. A total of 529 patients with indwelling catheters from January to December 2015 were treated with MTP intervention. The occurrence of indwelling catheter–associated urinary tract infections in the intensive care unit was compared before and after intervention. Results The incidence of indwelling catheter-associated urinary tract infections before and after MTP intervention were different, and the difference was statistically significant (P<0.05). Conclusion MTP intervention model can effectively prevent and reduce indwelling catheter-associated urinary tract infections in ICU.
