Effective Laparoscopic Catheter Insertion Technique for Peritoneal Dialysis Using Specially Designed Trocar:22 Years Multi-Center Retrospective Study of 804 Patients

Introduction: Literature reveals several peritoneal dialysis laparoscopic catheter insertion techniques developed to improve long-term results for treatment chronic kidney failure with the technic of peritoneal dialysis. The purpose of the study is evaluation of developed and recommended minimally invasive laparoscopic technic for chronic peritoneal dialysis catheter placement using specially constructed trocar. Materials and Methods: Retrospective study included 804 patients in 10 departments of surgery. Surgical and non surgical complications related to PD catheter placement were analysed: bleeding, dialysate leak, early SSI, peritonitis, catheter tip migration, catheter obstruction, omental wrapping and visceral perforations. Available software (Microsoft? Excel for Windows 10, MedCalc, Mariakerke, Belgium) was used for statistical analysis (presented as percentages, mean ± SD or median). Conclusions: The presented technique with specially constructed trocar is a simple and effective procedure with fewer complications comparing to literature. The advantages of this method include long rectus sheath tunnel with the deep cuff placed pre-peritoneally, the small size of the entrance into the peritoneum and accurate position and control of catheter tip in the pelvis.

Abdominal hemorrhage after peritoneal dialysis catheter insertion:A rare cause of luteal rupture:A case report

BACKGROUND Abdominal hemorrhage is a complication of peritoneal dialysis catheter(PDC)insertion that cannot be neglected,and its causes are mainly related to surgical injury.This article reports a case of massive abdominal hemorrhage that was caused by a rare rupture of corpus luteum shortly after PDC during the initiation of peritoneal dialysis(PD)insertion.CASE SUMMARY A 37-year-old woman was surgically placed a Tenckhoff catheter because of endstage renal disease.On the third postoperative day,the color of the abdominal drainage fluid was pink,and deepened gradually.It turned pale after initiating conservative treatment.On the tenth postoperative day,the color of the abdominal drainage fluid suddenly turned dark red,and the color progressively deepened.The patient’s hemoglobin dropped from 88 g/L to 57 g/L.Abdominal computed tomography(CT)indicated abdominal effusion and a high-density shadow in the abdominal cavity.The surgeon performed a laparotomy and found that the corpus luteum had ruptured on the right side and a left ovarian blood body had formed.The gynecologist repaired the ovary and performed a bilateral oophoroplasty.After the operation,the patient stopped bleeding and hemodialysis was temporarily stopped.PD was resumed after half a month.The patient’s condition improved,and she was discharged 14 d after the laparotomy.CONCLUSION If abdominal hemorrhage occurs in women of childbearing age after PDC insertion,luteal rupture should be considered as the cause.

Lower extremity peripherally inserted central catheter placement ectopic to the ascending lumbar vein:A case report

BACKGROUND Peripherally inserted central catheters(PICCs)are an essential infusion route for oncology patients receiving intravenous treatments,but lower extremity veni-puncture is the preferred technique for patients with superior vena cava syndrome(SVCS).We report the case of a patient with a lower extremity PICC ectopic to the ascending lumbar vein,to indicate and verify PICC catheterisation in the lower extremity is safe and feasible.And hope to provide different per-spectives for clinical PICC venipuncture to get the attention of peers.CASE SUMMARY On 24 August 2022,a 58-year-old male was admitted to our department due to an intermittent cough persisting for over a month,which worsened 10 d prior.Imaging and laboratory investigations suggested the patient with pulmonary malignancy and SVCS.Chemotherapy was not an absolute contraindication in this patient.Lower extremity venipuncture is the preferred technique because administering upper extremity venous transfusion to patients with SVCS can exacerbate oedema in the head,neck,and upper extremities.The patient and his family were informed about the procedure,and informed consent was obtained.After successful puncture and prompt treatment,the patient was discharged,experiencing some relief from symptoms.CONCLUSION Inferior vena cava catheterisation is rare and important for cancer patients with SVCS,particularly in complex situations involving ectopic placement.

Establishment and validation of a predictive model for peripherally inserted central catheter-related thrombosis in patients with liver cancer

BACKGROUND Peripherally inserted central catheters(PICCs)are commonly used in hospitalized patients with liver cancer for the administration of chemotherapy,nutrition,and other medications.However,PICC-related thrombosis is a serious complication that can lead to morbidity and mortality in this patient population.Several risk factors have been identified for the development of PICC-related thrombosis,including cancer type,stage,comorbidities,and catheter characteristics.Understanding these risk factors and developing a predictive model can help healthcare providers identify high-risk patients and implement preventive measures to reduce the incidence of thrombosis.AIM To analyze the influencing factors of PICC-related thrombosis in hospitalized patients with liver cancer,construct a predictive model,and validate it.METHODS Clinical data of hospitalized patients with liver cancer admitted from January 2020 to December 2023 were collected.Thirty-five cases of PICC-related thrombosis in hospitalized patients with liver cancer were collected,and 220 patients who underwent PICC placement during the same period but did not develop PICC-related thrombosis were randomly selected as controls.A total of 255 samples were collected and used as the training set,and 77 cases were collected as the validation set in a 7:3 ratio.General patient information,case data,catheterization data,coagulation indicators,and Autar Thrombosis Risk Assessment Scale scores were analyzed.Univariate and multivariate unconditional logistic regression analyses were performed on relevant factors,and the value of combined indicators in predicting PICC-related thrombosis in hospitalized patients with liver cancer was evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Univariate analysis showed statistically significant differences(P<0.05)in age,sex,Karnofsky performance status score(KPS),bedridden time,activities of daily living impairment,parenteral nutrition,catheter duration,distant metastasis,and bone marrow suppression between the thrombosis group and the non-thrombosis group.Other aspects had no statistically significant differences(P>0.05).Multivariate regression analysis showed that age≥60 years,KPS score≤50 points,parenteral nutrition,stage III to IV,distant metastasis,bone marrow suppression,and activities of daily living impairment were independent risk factors for PICC-related thrombosis in hospitalized patients with liver cancer(P<0.05).Catheter duration of 1-6 months and catheter duration>6 months were protective factors for PICC-related thrombosis(P<0.05).The predictive model for PICC-related thrombosis was obtained as follows:P predictive probability=[exp(Logit P)]/[1+exp(Logit P)],where Logit P=age×1.907+KPS score×2.045+parenteral nutrition×9.467+catheter duration×0.506+tumor-node-metastasis(TNM)staging×2.844+distant metastasis×2.065+bone marrow suppression×2.082+activities of daily living impairment×13.926.ROC curve analysis showed an area under the curve(AUC)of 0.827(95%CI:0.724-0.929,P<0.001),with a corresponding optimal cut-off value of 0.612,sensitivity of 0.755,and specificity of 0.857.Calibration curve analysis showed good consistency between the predicted occurrence of PICC-related thrombosis and actual occurrence(P>0.05).ROC analysis showed AUCs of 0.888 and 0.729 for the training and validation sets,respectively.CONCLUSION Age,KPS score,parenteral nutrition,TNM staging,distant metastasis,bone marrow suppression,and activities of daily living impairment are independent risk factors for PICC-related thrombosis in hospitalized patients with liver cancer,while catheter duration is a protective factor for the disease.The predictive model has an AUC of 0.827,indicating high predictive accuracy and clinical value.

Viabahn Stent Graft for Inadvertent Insertion of a Central Venous Catheter in the Subclavian Artery

Subclavian artery (SCA) injuries associated with central venous catheter (CVC) insertion are uncommon yet lethal complications that typically require surgical treatment. This case report presents the case of a 94-year-old man with an iatrogenic right SCA injury resulting from a misplaced CVC. Computed tomography revealed the catheter piercing the right internal jugular vein to enter the right SCA and then reaching the aortic arch. Emergent endovascular treatment was performed, and a 13-mm × 50-mm self-expanding Viabahn stent graft (W.L. Gore & Associates, Flagstaff, AZ, USA) was placed via the right brachial artery. The misplaced catheter was successfully removed under simultaneous postdeployment balloon dilatation. This case highlights the utility of the Viabahn stent graft for iatrogenic right SCA injury caused by a misplaced CVC and presents some insights and tips for a safer procedure.

Delayed cardiac tamponade diagnosed by point-of-care ultrasound in a neonate after peripherally inserted central catheter placement: A case report

BACKGROUND Peripherally inserted central catheters(PICCs)have been increasingly applied worldwide owing to many advantages.Even with these advantages,the related complications should not be ignored,especially in neonates.The available evidence about PICC-related thrombosis was manifold,but the cardiac tamponade,an emergency and life-threatening complication,has been rarely reported.Early recognized cardiac tamponade by ultrasound may reduce mortality.CASE SUMMARY A neonate weighting 2.8 kg was born at 40 wk of gestation.He was admitted to the Surgery Intensive Care Unit due to suspected congenital megacolon.A PICC line was inserted via the left antecubital fossa for the administration of total parenteral nutrition.Three days later,the patient was still on total parenteral nutrition.Cardiac tamponade caused by PICC was found on ultrasound.The patient recovered spontaneously after an emergency pericardiocentesis.CONCLUSION Proficiency in the use of point-of-care ultrasound may save the life of patients,since it enables clinicians to treat patients faster,more accurately,and in a noninvasive way at the point of care.

Arterial embolism caused by a peripherally inserted central catheter in a very premature infant:A case report and literature review

BACKGROUND Extremely premature infants have poor vascular conditions.Operators often choose deep veins such as the femoral vein and axillary vein to peripherally insert central catheters,and these vessels are often accompanied by arteries;thus,it is easy to mistakenly enter the artery.CASE SUMMARY The case of an extremely premature infant(born at gestational age 28+3)in whom the left upper extremity artery was accidentally entered during peripheral puncture of the central venous catheter is reported.On the 19th day of hospitalization,the index finger,middle finger and ring finger of the left hand were rosy,the left radial artery and brachial artery pulse were palpable,the recovery was 95%,and the improvement was obvious.At discharge 42 d after admission,there was no abnormality in fingertip activity during the follow-up period.CONCLUSION Arterial embolization in preterm infants requires an individualized treatment strategy combined with local anticoagulation and 2%nitroglycerin ointment for local tissue damage caused by arterial embolism in the upper limb.Continuous visualization of disease changes using image visualization increases the likelihood of a good outcome.

Diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy

Objective:The aim of our research was to study the incidence,clinical diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy.Methods:The data of the incidence,diagnosis and treatment of PICC-related sepsis in 215 cases of breast cancer patients carrying PICC catheter for chemotherapy in our hospital from August,2009 to September,2011 were analyzed retrospectively.Results:216 PICCs had been successfully applied in 215 cases of breast cancer patients and followed for a total of 19,109 catheter days,(median catheterization duration,88.9 days,range 1-212 days).Among those,3(1.39%) PICCs were removed respectively as a result of PICC-related sepsis in 29,73 and 108 catheter-days(median 70 d),with a rate of 0.16 per 1000 catheter-days.Conclusion:Chemotherapeutic treatment via PICC for breast cancer patients is one of the most secure and effective measures but there exists small number of cases in which PICC catheter related sepsis is possible.Careful observation of relevant symptoms and signs,early diagnosis and treatment,not relying completely on blood culture tests and timely removal of PICC catheter can be very effective in treating PICC-related sepsis in these patients.

Peripherally inserted central catheter placement in neonates with persistent left superior vena cava: Report of eight cases

BACKGROUND Reports on peripherally inserted central catheter(PICC)placement in neonates with persistent left superior vena cava(PLSVC)are rare.The majority of PLSVC patients have no clinical symptoms or hemodynamic changes,which are usually detected during cardiac catheterization,cardiac pacemaker implantation,or PICC placement.However,in neonates with PLSVC,PICC placement can be challenging.Here,we report PICC placement in eight neonates with PLSVC.CASE SUMMARY This article introduces the concept of the“TIMB”bundle.After PICC implantation,we found PLSVC in all eight patients.The key points of care regarding PICC placement in neonates with PLSVC included“TIMB”,where“T”indicates a reasonable choice of the catheterization time,“I”refers to a retrospective analysis of imaging data before catheterization,“M”refers to correct measurement of the body surface length,and“B”indicates that the tip of the PICC is placed in the middle and lower 1/3 of the left superior vena cava under the guidance of B-ultrasound.CONCLUSION“TIMB”is a bundle for PICC placement in neonates,especially for those with PLSVC.Using this new approach can improve the first-attempt success rate of PICC placement,reveal cardiovascular abnormalities in advance,allow the selection of different measurement methods reasonably according to the puncture site,and finally,improve the accuracy of catheter positioning through the use of B-ultrasound guidance.

A Peripherally Inserted Central Vein Catheter Fractured and Slid into the Right Pulmonary Artery:A Case Report

Catheter fracture is a rare but serious complication of a peripherally inserted central catheter （PICC）. An adolescent patient was sent to Tianjin Medical University General Hospital （Tianjin, China） because the PICC was fractured when removed by a nurse. Chest X-ray showed that the PICC fragment slid into the right pulmonary artery. Through emergency surgery, the remainder of the PICC was successfully retrieved by an interventional operation percutaneously via the right femoral vein. PICC fracture is less common and always without significant discomfort if not found timely, and it may lead to serious complications, such as pulmonary embolism, and even death. Thus, nurses, patients and their family members should pay enough attention to the daily maintenance of PICC and have a deep understanding of the reasons associated with PICC fracture as well as how to prevent it. Interventional operation is minimally invasive, which is a good choice for the removal of intravascular foreign bodies, leading to fewer complications and a good prognosis.

Thoracic duct cannulation during left internal jugular vein cannulation:A case report

BACKGROUND Central venous catheter insertion is an invasive procedure that can cause complications such as infection,embolization due to air or blood clots,pneumothorax,hemothorax,and,rarely,chylothorax due to damage to the thoracic duct.Herein,we report a case of suspected thoracic duct cannulation that occurred during left central venous catheter insertion.Fortunately,the patient was discharged without any adverse events related to thoracic duct cannulation.CASE SUMMARY A 46-year-old female patient presented at our department to undergo cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.During anesthesia,we decided to insert a central venous catheter through the left internal jugular vein because the patient already had a chemoport through the right central vein.During the procedure,blood reflux was observed when the needle tip was not within the ultrasound field of view.We did not try to find the tip;however,a guide wire and a central venous catheter were inserted without any resistance.Subsequently,when inducing blood reflux from the distal port of the central venous catheter,only clear fluid,suspected to be lymphatic fluid,was regurgitated.Further,chest X-ray revealed an appearance similar to that of the path of the thoracic duct.Given that intravenous fluid administration was not started and no abnormal fluid collection was noted on preoperative chest X-ray,we suspected thoracic duct cannulation.CONCLUSION It is important to use ultrasound to confirm the exact position of the needle tip and guide wire path.

Venous thromboembolism in patients with liver cancer:a retrospective study

Background:Little is known about the association between venous thromboembolism(VTE)and tumors.In this study,we identified the clinical features of patients with liver cancer who presented with at least 1 VTE episode.Methods:This was a retrospective case-control study of a single-institution database with univariate and multivariate analyses usingχ^(2)and Fisher exact tests.Statistical significance was set at P<0.05.Results:The overall incidence of VTE in the patients with liver cancer was 1.2%.More than half(53.8%)of the 13 patients with liver cancer and venous thrombosis died within 2 months.The thrombus in 12 patients(92.3%)was located within the deep veins,whereas the other patient(7.7%)was diagnosed with a pulmonary embolism.Of the 11 patients,9(69.2%)had swelling and/or pain symptoms.All 6 patients with peripherally inserted central catheters(PICCs)had thrombosis,accounting for 46.2%of all patients with liver cancer and venous thrombosis.Compared with the controls,liver cancer patients with PICC tubes,thrombosis-related symptoms such as swelling and pain,traumatic stimulation such as fracture,acute respiratory distress syndrome,and interventional therapy or hemostasis drugs were prone to be diagnosed with VTE(P<0.05).Conclusions:Liver cancer and thrombosis are rare and have poor prognoses.Liver cancer with thrombosis may be associated with PICC catheterization,traumatic stimulation,or hemostatic drugs.Patients with liver cancer and thrombosis often present with swelling and pain.

Central Line Associated Bloodstream Infection in Adult Intensive Care Unit Population—Changes in Epidemiology, Diagnosis, Prevention, and Addition of New Technologies

Background: Intensive care units (ICUs) have an increased risk of Central line associated bloodstream infection (CLABSI) due to the prevalence of invasive procedures, devices, immunosuppression, comorbidity, frailty, and elderly patients. We have seen a successful reduction in Central line associated bloodstream infection related the past decade. In spite of this, Intensive care unit-Catheter related bloodstream infections remain high. The emergence of new pathogens further complicates treatment and threatens patient outcomes in this context. In addition, the SARS-CoV-2 (COVID-19) pandemic served as a reminder that an emerging pathogen poses a challenge for adjusting prevention measures regarding both the risk of exposure to caregivers and maintaining a high level of care. ICU nurses play an important role in the prevention and management of CLABSI as they are involved in basic hygienic care, quality improvement initiatives, microbiological sampling, and aspects of antimicrobial stewardship. Microbiological techniques that are more sensitive and our increased knowledge of the interactions between critically ill patients and their microbiota are forcing us to rethink how we define CLABSIs and how we can diagnose, treat, and prevent them in the ICU. The objective of this multidisciplinary expert review, focused on the ICU setting, is to summarize the recently observed occurrence of CLABSI in ICU, to consider the role of modern microbiological techniques in their diagnosis, to examine clinical and epidemiological definitions, and to redefine several controversial preventive measures including antimicrobial-impregnated catheters, chlorhexidine-gluconate impregnated sponge, and catheter dressings.

Appropriate posture of cancer patients treated with PICC to prevent internal jugular vein ectopic

We aimed to study the appropriate posture of peripherally inserted central catheter （PICC） patients, to reduce the incidence of internal jugular vein heterotopia. Methods： From 2009 to 2013, a total of 290 cases with PICC were enrolled in our study. They were divided into two groups. The patients in control group took regular position, which mean pros- tration, upper limb of tube side was abduction 90°, head moved to puncture side in order to block the internal jugular vein. On the basis of conventional body position putting, posture of patients in observation group was improved, the head remain neutral, and had 180° angle with trunk longitudinal axis, not favor any side. After ensuring the upper limb abduction, had 90° angle with the trunk, then catheter was inserted slowly. The jugular venous catheter heterotopia rate was judged by X.ray results. Results： The jugular venous catheter heterotopia rate of control group and observation was 12.8% and 0.68%, respectively. The difference between two groups was statistically significant （P 〈 0.01）. Conclusion： The body posture improvement can prevent discomfort of patients and reduce the jugular venous catheter heterotopia rate of PICC.

Tip orientation under real-time point-of-care neck ultrasonic monitoring is advantageous in peripherally inserted central catheter procedures:a retrospective cohort study

Background:We analyzed the success and catheter tip malposition rates of peripherally inserted central catheter(PICC)placement using ultrasonic monitoring.Methods:A total of 564 patients were recruited and assigned to either the intervention or control group.In the intervention group,282 patients underwent ultrasound-guided PICC insertion,which helped to identify the position and depth of the catheter tip.From a total of 9000 patients,282 were selectively chosen to receive the traditional method using body surface measurements(control group).The primary endpoint was the success rate;the secondary endpoint was the catheter tip malposition rate as detected by postprocedure chest radiography.Results:In the intervention group,a total of 94 catheters were in a suboptimal position;26 were too deep,68 were too shallow,and 1 was inserted into the subclavian vein,with success and malposition rates of 66.3%and 0.4%,respectively.In the control group,139 catheters were in a suboptimal position;88 were too deep,51 were too shallow,9 were inserted into the jugular vein,and 2 were inserted into the subclavian vein,with success and malposition rates of 46.8%(P<0.001)and 3.9%(P=0.004),respectively.Significant differences were observed in success and malposition rates between the 2 groups.Conclusion:Ultrasound-guided PICC procedures achieved higher success rates and lower malposition rates.

Hot Compress with Chinese Herbal Salt Packets Reducing PICC Catheter Complications: A Randomized Controlled Trial

Objective： To explore the preventive effect of applying hot compress with Chinese herbal salt packets（CHSP） to puncture vessels under aseptic conditions during peripherally inserted central catheter（PICC） on postoperative phlebitis. Methods： A total of 720 hospitalized patients undergoing first PICC were assigned to treatment and control groups（360 cases each group） according to a random number table. The control group received conventional catheterization and nursing care. The treatment group was first given hot compress with CHSP（which consisted of honeysuckle 30 g, Semen brassicae 30 g, Salvia miltiorrhiza 30 g, Angelica dahurica 30 g, Semen raphani 30 g, Evodia rutaecarpa 30 g, and coarse salt 20 g） on the punctured vessel under aseptic conditions for 5–10 min before conventional catheterization. The main efficacy indices were the vessel diameters before and during catheterization and the success rate of a single catheter, and the secondary efficacy indiex was the incidence of superficial phlebitis within 1 week after catheterization. Results： The vessel diameter during catheterization of the treatment group was remarkably increased compared with the control group [（7.96±0.42） mm vs.（4.39±0.54） mm, P〈0.01]. The success rate of the single catheter of the treatment group was significantly higher than that of the control group [94.00%（329/350） vs. 73.72%（244/329）, P〈0.01]. The incidence of superficial phlebitis within 1 week after catheterization in the treatment group was lower than that in the control group（P=0.007）. There was no adverse event with CHSP. Conclusion： Hot compress with CHSP during PICC is applicable as it can effectively improve the success rate of a single catheter and reduce the incidence of superficial phlebitis after catheterization（Trial registration No. ChiCTR-ONC-17010498）.
