The Impact of Patient Education on the Nursing Care of Perioperative Patients in the Interventional Catheterization Room

Objective:To explore and analyze the effect of implementing a precise education model on the nursing care of perioperative patients in the interventional catheterization room.Methods:We selected 70 patients who were going to undergo surgical intervention in our hospital from August 2020 to December 2022 as the subjects for this study through random sampling.The patients were divided into a control group and an observation group,with 35 cases in each group.The control group underwent basic nursing intervention,and the observation group was given precise patient education.The nursing effects of both groups were observed.Results:After the intervention,all compliance indicators of the observation group were better than those of the control group(P<0.05).Besides,the incidence of complications in the observation group(2.86%)was lower than that of the control group(17.14%)with P<0.05.Furthermore,the patient satisfaction of the observation group(97.14%)was higher than that of the control group(82.86%),with P<0.05.Conclusion:A precise propaganda and education model facilitates the nursing of perioperative patients in the interventional catheterization room.Therefore,this practice should be popularized.

Anatomical variation in the internal jugular vein:potential risk factors for central venous catheterization-a case report

Central venous catheterization(CVC)is an invasive medical procedure used to measure central venous pressure and provides a stable route for continuous drug administration.CVC is widely used in the emergency department and intensive care units.It is typically performed by inserting a catheter through the internal jugular vein(IJV)into the superior vena cava near the right atrium.[1,2]While catheterization is a fundamental skill proficiently performed by healthcare professionals,lethal complications may occasionally occur because of undesirable positioning,depth and diameter.

How to manage the malposition of deep vein catheterization into the artery?

Central venous catheterization establishes temporary,efficient,and rapid use of deep venous access in patients,which provides high flow rate fluid perfusion,enables measurement of central venous pressure,and acts as an important reference for clinical decision-making.However,various complications such as pneumothorax,hemothorax,hematoma,and puncture failure can easily occur during the puncture and catheterization process.

Analysis of the Nursing Effect of Hierarchical Extended Nursing Based on The Guidance of Orem’s Theory in Patients with PICC Catheterization

Objective:To analyze the nursing effect of hierarchical extended nursing based on the guidance of Orem’s theory in patients with peripherally inserted central(PICC)catheterization.Methods:Ninety-one patients with PICC catheterization admitted to the hospital from May 2021 to May 2023 were selected and divided into a control group and an observation group,with 45 and 46 cases,respectively.The control group received routine nursing care,while the observation group received routine nursing care combined with hierarchical extended nursing based on the guidance of Orem’s theory for 3 months.Relevant indicators between the two groups were compared.Results:The improvement degree of various indicators in the observation group after nursing was better than that of the control group(P<0.05).Conclusion:Graded extended nursing based on the guidance of Orem’s theory improved the knowledge,belief,behavior,and self-efficacy of patients with PICC catheterization,and relieved their anxiety,depression,and other negative emotions.The nursing effect was deemed to be significant.

Pulmonary arterial hypertension confirmed by right heart catheterization following COVID-19 pneumonia: A case report and review of literature

BACKGROUND Pulmonary arterial hypertension(PAH)is a disease of the arterioles resulting in an increased resistance in pulmonary circulation with associated high pressures in the pulmonary arteries,causing irreversible remodeling of the pulmonary arterial walls.Coronavirus disease 2019(COVID-19)has been associated with development of new onset PAH in the literature leading to symptoms of dyspnea,cough and fatigue that persist in spite of resolution of acute COVID-19 infection.However,the majority of these cases of COVID related PAH were diagnosed using echocardiographic data or via right heart catheterization in mechanically ventilated patients.CASE SUMMARY Our case is the first reported case of COVID related PAH diagnosed by right heart catheterization in a non-mechanically ventilated patient.Right heart catheterization has been the gold standard for diagnosis of pulmonary hypertension.Our patient had right heart catheterization four months after her initial COVID-19 infection due to persistent dyspnea.CONCLUSION This revealed new onset PAH that developed following her infection with COVID-19,an emerging sequela of the infection.

Early Cardiac Catheterizations within 30 Days Post Congenital Heart Surgery in Children

Background:This study set out to assess the indications,feasibility,safety,and outcome of early cardiac catheterizations(CC)within 30 days after congenital heart surgery(CHS)in children.Methods and Results:This is a retrospective,single-center case review study of all CC within 30 days after CHS between 1/2010-12/2020.A total of 317(138 diagnostic,179 interventional)CC were performed in 245 patients at a median of 4 days(IQR 13)after CHS.The median age was 3 months(IQR 6),and body weight was 5 kg(IQR 4).A total of 194(61.2%)CC were performed in patients with univentricular hearts.CC revealed significant pathologies leading to early redo-surgery in 37 patients(12%).The transcatheter interventions primarily were needed in patients after cavo-pulmonary connection(n=69%,21.8%),right ventricle to pulmonary artery conduit(n=39%,12.3%),and Norwood-I surgery(n=34%,10.7%)presenting with hypoxemia,prolonged postoperative course,and suspected arterial stenosis on echocardiography.The clinical impact of an early postoperative transcatheter intervention for the following clinical course was high in most cases.There were nine(2.8%)major and 20(6.3%)minor intra-procedural complications.Risk factor analysis revealed no difference for the occurrence of complications for patients’age,weight,and time from initial CHS,underlying uni-vs.biventricular heart disease,or ECMO.Conclusion:Early CC within 30 days after CHS in children can be performed safely with a high diagnostic and therapeutic value.The rate of complications is low,while the therapeutic consequence is relevant.

Effects of General Anesthesia on the Results of Cardiac Catheterization in Pediatric Patients with Ventricular Septal Defect

Background:There is no gold standard sedation method for pediatric cardiac catheterization.In congenital heart diseases with intracardiac shunts,hemodynamic parameters are prone to change depending on the ventilation conditions and anesthetics,although few studies have examined these effects.The purpose of this study was to investigate the effects of two different sedation methods on the hemodynamic parameters.Methods:This study retrospectively evaluated consecutive patients with ventricular septal defect(VSD)below 1 year of age who underwent cardiac catheterization at Aichi Children’s Health and Medical Center,who were divided into age-and VSD diameter-matched general anesthesia(GA)and monitored anesthesia care(MAC)under the natural airway groups(n=40 each),for comparison of hemodynamic parameters.Results:In the GA group,arterial blood pH and arterial partial pressure of oxygen were significantly higher(p<0.01),whereas arterial partial pressure of carbon dioxide was significantly lower than in the MAC group(p<0.01).Mean pulmonary artery pressure(p<0.05)and systemic blood pressure(p<0.01)were lower in the GA group.Pulmonary vascular resistance index(p<0.01)and systemic vascular resistance index(p<0.01)were also significantly lower in the GA group than the MAC group.There were no significant differences in pulmonary blood flow index,systemic blood flow index,and pulmonary/systemic blood flow ratio between the two groups.Conclusions:Cardiac catheterization under GA in VSD patients results in different hemodynamic parameters compared to that under MAC.In particular,when using pulmonary artery pressure and pulmonary vascular resistance measured under GA for judgment regarding the surgical indications or perioperative management,consideration should be given to the fact that these parameters might be lower compared to those measured under MAC.

Iatrogenic bladder neck rupture due to traumatic urethral catheterization: A case report

BACKGROUND In this article,we present a case of iatrogenic bladder neck rupture due to catheter insertion in a 94-year-old comorbid male patient.CASE SUMMARY The patient,who had a urethral catheter inserted in the palliative service 3 d ago,was consulted because the catheter did not work.Because the fluid given to the bladder could not be recovered,computed tomography was performed,which revealed that the catheter had passed the bladder neck first into the retrovesical area then into the intraabdominal area.The appearance of the anterior urethra and verumontanum was normal at cystoscopy.However,extremely severe stenosis of the bladder neck,and perforated posterior wall of the urethral segment between the prostatic urethra and the bladder neck were observed.Internal urethrotomy was applied to the bladder neck with a urethrotome.An urethral catheter was sent over the guide wire into the bladder.The patient was followed in the palliative care service and the catheter was removed 7 d later.No extravasation was observed in the control urethrography.CONCLUSION Although catheter insertion is a simple and frequently performed procedure in hospitalized patients,it is necessary to avoid unnecessary extra-indication catheter insertion.

Median neuropathy after multiple punctures of the forearm for catheterization:A case report

BACKGROUND Neuropathy may occur at some sites after catheterization for close examination of cardiac disease.Although the radial artery is considered a relatively uncomplicated site for catheterization,the radial artery and median nerve are in relatively close proximity,with the risk of median nerve injury depending on the angle of puncture.The purpose of this study was to report the outcomes of surgery performed for conservative therapy-resistant median neuropathy following forearm catheterization.CASE SUMMARY A 50-year-old woman experienced palsy from the right thumb to the radial side of the ring finger after catheterization from the radial artery of the right forearm.Paresthesia developed at the same site and a positive tinel-like sign was seen for the median nerve area at the high level of the puncture site.Nerve conduction study showed reduced compound muscle action potentials and loss of sensory nerve action potentials.Symptoms did not improve despite pharmacotherapy and the patient gradually developed flexion restrictions of the index and middle fingers.Median nerve injury and associated flexor tendon adhesion was diagnosed,and the patient was referred for surgery at 3 mo after injury.When the same area was opened,no injury to the median nerve epithelium was obvious,but the area of the positive tinel-like sign was highly adherent to surrounding tissue and to the flexor digitorum superficialis of the index and middle fingers.The surgery was terminated with adequate adhesion release.Rehabilitation was initiated postoperatively,improving neurological symptoms and range of motion of the fingers.Six months after surgery,the patient returned to daily activities without discomfort.CONCLUSION This case provides the appropriate diagnosis and treatment for a suspected peripheral nerve injury.

Place of Selective Tubal Catheterization in the Management of Female Infertility in Togo

Objective: To determine the effectiveness of selective tubal catheterization in the management of female infertility due to proximal tubal obstruction. Method: This was a longitudinal descriptive study, conducted over a period of 24 months, which included 73 patients presenting with objectified bilateral proximal tubal obstruction after standard HSG. The intervention was performed on an outpatient basis, during the follicular phase with negative β-hCG assay the day before, in the interventional radiology room and under antibiotic coverage. Confirmatory hysterosalpingography was performed as the first step followed by selective tubal catheterization after the failure of spontaneous tubal opacification. The parameters studied related to socio-epidemiological, clinical and radiological data. Results: The age of our patients was between 24 and 42 years with an average of 33.97 years. The average duration of infertility was 3.95 years, with a predominance of primary infertility in 83.56% of cases. Voluntary termination of pregnancy (38.89%) and fibromyomas (33.33%) were the most represented gynecological-obstetrical antecedents. Selective tubal catheterization was successful in 92.14% of cases (129/140 tubes). It was possible bilaterally in 93.02% of cases and unilaterally in 6.98% of cases. The confirmatory HSG allowed a spontaneous opacification of 4.10% of the fallopian tubes. At the end of the procedure, all the recanalized tubes were opacified;62.01% of them were normal, against 37.99% pathological with a preponderance of inflammatory tubes 26.61% followed by hydrosalpinx in 5.03% of cases. No major complications were encountered. The fertility rate was 23.29%. Conclusion: Selective tubal catheterization is a simple technique, without major complications with an efficiency close to natural fertility. It should be proposed as the first intention before any other procedure in the treatment of infertility by proximal tubal obstruction.

Development and validation of a risk prediction model for repeated indwelling urinary catheterization in patients with cervical cancer after surgery

Objective:To study the factors influencing secondary indwelling catheterisation after cervical cancer surgery and to develop a predictive risk model.Methods:A total of 260 patients in a tertiary hospital in Chongqing were selected from January 2020 to December 2021 via convenience sampling.Relevant information of patients was recorded,including age;body mass index;history of hypertension and diabetes,bladder dysfunction,postoperative urinary retention,and postoperative urinary tract infection;Histology;staging;surgical approach;Operation time;Time of first remove of catheter;indwelling catheter days;Hospitalization days.Least absolute shrinkage and selection operator was used to reduce dimensionality and select patient characteristics,and multivariate analysis was performed based on the selected variables.Based on the outcome of analysis,a line chart model was developed for predicting the risk of secondary catheterization in patients with indwelling catheterization after radical cervical cancer surgery.The coefficient of conformity index(C-index)and calibration curves were used to evaluate the accuracy and fit.The model was internally validated via bootstrapping(1000 random samples),and the clinical utility of the model was assessed via decision curve analysis(DCA).Results:Four characteristic variables were selected,including preoperative bladder function,postoperative urinary tract infection,surgical approach,and Time of first remove of catheter.They are independent risk factors affecting urinary tract.The risk prediction model exhibited good discrimination performance with a C-index of 0.722(95%CI,0.661-0.783)and was well calibrated.The C-index was 0.708 in internal validation analysis.DCA showed that the risk model was clinically useful for predicting secondary catheterization,and clinical benefits were observed at the decision threshold of≥11%.Conclusion:A novel model was developed to predict the risk of secondary catheterization.The model was based on preoperative bladder dysfunction,postoperative urinary tract infection,surgical approach,and number of days since the removal of the primary catheter.

Central venous catheterization-related complications in a cohort of 100 hospitalized patients:An observational study

Objective:To evaluate the complications of central venous catheterization(CVC).Methods:A prospective,observational study was conducted at a tertiary care center in India from December 2018 to September 2020.Critically ill patients(aged≥18 years)in the intensive care unit undergoing CVC procedures were included in the study.Baseline demographics and detailed medical history were recorded.Chest X-rays and electrocardiography were performed on all the patients.Complications associated with CVC were recorded.Results:A total of 100 patients with the indication for central venous catheter insertion were included.The majority(81%)of the patients were inserted with CVC at the right internal jugular vein.Complications such as arterial puncture(2%),hematoma(4%),blood clot formation(4%),catheter kinking(3%),thoracic injury(1%),thrombophlebitis(6%),sepsis(9%)and nerve injury(1%)were reported.Conclusions:Though central venous access is preferred in management of critically ill patients,it has its risks.However,early recognition and prompt management of complications may reduce mortality and morbidity.Physicians and intensive care unit intensivists should be vigilant for central venous catheter-related complications.Suitable site selection,operator experience,and proper catheter maintenance are associated with optimal outcomes.

Comparison of intraosseous access and central venous catheterization in Chinese adult emergency patients: A prospective, multicenter, and randomized study

BACKGROUND: It is challenging to establish peripheral intravenous access in adult critically patients. This study aims to compare the success rate of the first attempt, procedure time, operator satisfaction with the used devices, pain score, and complications between intraosseous(IO) access and central venous catheterization(CVC) in critically ill Chinese patients.METHODS: In this prospective clustered randomized controlled trial, eight hospitals were randomly divided into either the IO group or the CVC group. Patients who needed emergency vascular access were included. From April 1, 2017 to December 31, 2018, each center included 12 patients. We recorded the data mentioned above.RESULTS: A total of 96 patients were enrolled in the study. There were no statistically significant differences between the two groups regarding sex, age, body mass index, or operator satisfaction with the used devices. The success rates of the first attempt and the procedure time were statistically significant between the IO group and the CVC group(91.7% vs. 50.0%, P<0.001;52.0 seconds vs. 900.0 seconds, P<0.001). During the study, 32 patients were conscious. There was no statistically significant difference between the two groups regarding the pain score associated with insertion. There were statistically significant differences between the two groups regarding the pain score associated with IO or CVC infusion(1.5 vs. 0.0, P=0.044). Complications were not observed in the two groups.CONCLUSIONS: IO access is a safe, rapid, and effective technique for gaining vascular access in critically ill adults with inaccessible peripheral veins in the emergency departments.

A comparative study of TR Band and a new hemostatic compression device after transradial coronary catheterization

Objective: Transradial coronary catheterization has proved to be safe and effective in clinical practice. Various hemostatic compressive devices have been used in subsequent procedures. The objective of this study was to compare the efficacy and safety of a new hemostatic compression device and the widely used TR Band. Methods: A total of 118 patients were divided randomly into two groups: TR Band and the new hemostatic compression device. Efficacy of hemostasis, patient comfort, local vascular dysfunction, and radial artery occlusion(RAO) were evaluated and compared between groups. Results: Occurrence of errhysis or hematoma did not significantly differ between groups(13.6% vs. 11.9%, P = 0.782). Fewer patients had moderate to severe pain or moderate to severe numbness in the new hemostatic compression device group(1.7% vs. 22.0%; 1.7% vs. 18.6%, respectively). Pulse loss between distal artery and device was lower in the new hemostatic compression device group(5.1% vs. 22.0%, P = 0.007), and fewer patients experienced obstruction of venous reflux compared with the TR Band group(6.8% vs. 25.4%, P = 0.006). Combined incidence of RAO at discharge was 7.6%, and was lower in the new hemostatic compression device group(1.7% vs. 13.6%, P = 0.015). In contrast to the TR Band, application of the new hemostatic compression device was independently associated with lower incidence of RAO at discharge(odds ratio: 0.062, 95% confidence interval: 0.006–0.675, P = 0.022). Conclusions: Both the new hemostatic compression device and the TR Band can efficiently achieve hemostasis following transradial coronary catheterization. However, fewer patients felt discomfort with application of the new hemostatic compression device. Pulse loss in the artery distal to the compression device, obstruction of venous reflux, and RAO occurred significantly less often with application of the new device.

Catheterization of the gallbladder: A novel mouse model of severe acute cholangitis

AIM To establish a severe acute cholangitis(SAC) model in mice.METHODS Cholecystic catheterization was performed under the condition of bile duct ligation(BDL). Trans-cholecystic injection of lipopolysaccharide(LPS) was defined as the SAC animal model. Sham operation group, intraperitoneal injection of LPS without BDL group, intraperitoneal injection of LPS with BDL group and trans-cholecystic injection of normal saline with BDL group were defined as control groups. The survival rates and tissue injuries in liver, lungs and kidney were evaluated.RESULTS Mice in the SAC group showed a time-dependent mortality and much more severe tissue injuries in liver, lungs and kidney, compared with other groups. However, relieving biliary obstruction could effectively reduce mortality and attenuate liver injury in the SAC mouse model.CONCLUSION Trans-cholecystic injection of LPS under the condition of biliary obstruction could establish a repeatable and reversible mouse model of SAC.

Bladder perforation caused by long-term catheterization misdiagnosed as digestive tract perforation:A case report

BACKGROUND Spontaneous bladder rupture is relatively rare,and common causes of spontaneous bladder rupture include bladder diverticulum,neurogenic bladder dysfunction,gonorrhea infection,pelvic radiotherapy,etc.Urinary bladder perforation caused by urinary catheterization mostly occurs during the intubation process.CASE SUMMARY Here,we describe an 83-year-old male who was admitted with 26 h of middle and upper abdominal pain and a history of long-term catheterization.Physical examination and computed tomography of the abdomen supported the diagnosis of diffuse peritonitis,most likely from a perforated digestive tract organ.Laparoscopic exploration revealed a possible digestive tract perforation.Finally,a perforation of approximately 5 mm in diameter was found in the bladder wall during laparotomy.After reviewing the patient's previous medical records,we found that 1 year prior the patient underwent an ultrasound examination showing that the end of the catheter was embedded into the mucosal layer of the bladder.Therefore,the bladder perforation in this patient may have been caused by the chronic compression of the urinary catheter against the bladder wall.CONCLUSION For patients with long-term indwelling catheters,there is a possibility of bladder perforation,which needs to be dealt with quickly.

Effects of oral premedication on cognitive status of elderly patients undergoing cardiac catheterization

Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients 〉 70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze- pam （25 rag/5 mg） or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess- ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients＇ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale （VAS）. The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer＇s Assessment of Alermess/Sedation Scale （OAA/S）. Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients＇ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group （P 〈 0.05 for both）. Nurses reported an improvement with patient management in the pre-medicated group （P = 0.08）. Conclusions In conclusion, prcmedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

Clinical Application of Newborn Umbilical Vein Catheterization Combining with PICC

Purpose: Research on clinical application effect of combining very low birth weight newborn (VLBWN) umbilical vein catheterization (UVC) with peripherally inserted central catheter (PICC). Method: 60 cases of VLBWN checked in our hospital’s ICU are selected and divided into combination group (n = 30) and PICC group (n = 30) according to the random number table. Combination of UVC and PICC is applied on newborn of combination group while only PICC is applied on newborn of PICC group. These two groups’ newborn’s PICC catheterization operation time, PICC indwelling time, weight gain, hospital stays, hospital infection, planned extubation, successful single puncture, adverse events and other indexes are observed. Result: Newborns in combination group have less PICC catheterization operation time and less hospital stays than newborns in PICC group while newborns in combination group have longer PICC indwelling time and greater weight gain than newborns in PICC group. The difference here has statistical significance (p < 0.05). Combination group’s hospital infection ratio (3.33%) is lower than that of PICC group (23.33%). The difference here has statistical significance (p < 0.05). Newborns in combination group have a planned extubation rate of 93.33% and a successful single puncture rate of 93.33%, which are greater than those of newborn in PICC group (respectively 73.33% and 70.00%). The difference here has statistical significance (p < 0.05). Newborns in combination group have an adverse event occurrence rate of 43.33%, lower than that of PICC group (70.00%). The difference here has statistical significance (p < 0.05). Conclusion: Application of combination of UVC and PICC on VLBWN can greatly improve PICC catheterization efficiency and newborn patients’ nutriture and reduce rate of complications, thus, it is worthy of clinical application.

Efficacy and safety of distal radial approach for cardiac catheterization: A systematic review and meta-analysis

BACKGROUND The traditional radial approach(RA)is recommended as the standard method for coronary angiography(CAG),while a distal RA(DRA)has been recently used for CAG.AIM To assess the efficacy and safety of the DRA vs RA during CAG.METHODS The following databases were searched through December 2020:MEDLINE,the Cochrane Central Register of Controlled Trials,EMBASE,the World Health Organization International Clinical Trials Platform Search Portal,and Clinical-Trials.gov.Individual randomized-controlled trials for adult patients undergoing cardiac catheterization were included.The primary outcomes were the successful cannulation rate and the incidence of radial artery spasm(RAS)and radial artery occlusion(RAO).Study selection,data abstraction and quality assessment were independently performed using the Grading of Recommendations,Assessment,Development,and Evaluation approach.RESULTS Three randomized control trials and 13 registered trials were identified.The two approaches showed similar successful cannulation rates[risk ratio(RR)0.90,95%confidence interval(CI):0.72-1.13].The DRA did not decrease RAS(RR 0.43,95%CI:0.08-2.49)and RAO(RR 0.48,95%CI:0.18-1.29).Patients with the DRA had a shorter hemostasis time in comparison to those with the RA(mean difference-6.64,95%CI:-10.37 to-2.90).The evidence of certainty was low.CONCLUSION For CAG,the DRA would be safer than the RA with comparable cannulation rates.Given the limited data,additional research,including studies with standard protocols,is necessary.

The Transradial Approach for Cardiac Catheterization and Percutaneous Coronary Intervention:A Review

Cardiac catheterization and percutaneous coronary intervention play an important role in the management of coronary artery disease.Although the transfemoral approach has been the traditionally dominant method,there has been an increased utilization of the transradial approach.Multiple observational studies and randomized clinical trials have shown fewer bleeding complications,reduced morbidity and mortality,improved quality of life,and better economic outcomes when the transradial approach is utilized when compared to the transfemoral approach.Despite its many benefits,utilization of this approach in certain countries including the United States has been less than optimal due to a lower adoption rates mostly driven by lack of training opportunities and decreased awareness of clinical benefits of the transradial approach.In this review,the history,observational trends,efficacy,and technical aspects of transradial cardiac catheterization and percutaneous coronary intervention are discussed.
