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.

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.

Focus on peripherally inserted central catheters in critically ill patients

Venous access devices are of pivotal importance for an increasing number of critically ill patients in a variety of disease states and in a variety of clinical settings(emergency, intensive care, surgery) and for different purposes(fluids or drugs infusions, parenteral nutrition, antibiotic therapy, hemodynamic monitoring, procedures of dialysis/apheresis). However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device(CVAD)(mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters(PICCs) and centrally inserted central catheters(CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe-due to their placement into peripheral veins of the armand the advantage of a central location of catheter tip suitable for all osmolarity and p H solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as wellas the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs(i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks associated with each type of CVAD(CICCs or PICCs). Second, an inappropriate CVAD choice and, particularly, an inadequate insertion technique are relevant-and often not recognized-potential risk factors for complications in critically ill patients. We strongly believe that all healthcare professionals involved in the choice, insertion or management of CVADs in critically ill patients should know all potential risk factors of complications. This knowledge may minimize complications and guarantee longevity to the CVAD optimizing the risk/benefit ratio of CVAD insertion and use. Proper management of CVADs in critical care saves lines and lives. Much evidence from the medical literature and from the clinical practice supports our belief that, compared to CICCs, the so-called power-injectable peripherally inserted central catheters are a good alternative choice in critical care.

An Unusual Peripherally Inserted Central Catheter (PICC) Fractured <i>in Vivo</i>with Embolization Happened in a Child: A Case Report

We report a case of a 7-year-old child who received a peripherally inserted central catheter (PICC) for chemotherapy. He suffered from an unusual PICC fracture in vivo with pulmonary embolism after eight circles of chemotherapeutic agents administered. In this case report, we review the literatures for the underlying pathophysiology of this uncommon phenomenon. IV nurses should consider the possibility of the infusion dysfunction deriving from the PICC line fractured. Accurate tip catheter placement and specific care may reduce morbidity.

Analysis of Use and Outcomes of Peripherally Inserted Central Catheter (PICC-Line) in Hemato-Oncological Patients

Aims: To audit the use and outcomes of using PICC lines in hemato-oncological patients. Objectives: To study the demographics of patients: ?studying the use of PICC line in hemato-oncological patients;studying the rate of complications in PICC line;studying the cause of early removal of PICC line. Methods: All PICCs inserted in adult hemato-oncological patients in Hematology and Medical Oncology Department of Health Care Global (HCG) Hospital were studied prospectively, as per the proforma, till PICCs were removed or patient expired and the pattern of complications were noted. Results: Eighty-four PICCs were inserted over a period of initial nine months and followed for a total of 1 year with three months post insertion duration for a total of 10,868 catheter-days (mean of 129 days i.e. 4.3 months, range: 1 to 288 days). The most common indication for PICC was chemotherapy (100%). Among them 19 (22%) PICCs had complications and 12 were removed at the rate of 1.1/1000 PICC-days. Complications with haematologic malignancies were more as compared to those with solid tissue malignancies. Conclusions: Despite significant complication rates, PICCs are a relatively safe and cost effective mode of establishing central venous access.

适于胎龄与小于胎龄的极低出生体重儿身长增长对PICC尖端移位的影响及比较

目的探讨极低出生体重儿(very low birth weight,VLBW)中适于胎龄儿(appropriate for gestational age,AGA)和小于胎龄儿(small for gestational age,SGA)身长增长对经外周中心静脉置管(peripherally inserted central catheter,PICC)尖端移位的影响,并横向比较影响程度,帮助医护人员更好地把握导管尖端位置监测的时机。方法回顾性分析2021年1月—2022年6月在医院NICU住院并使用PICC的VLBW,按出生体质量和胎龄关系分为AGA组45例和SGA组19例,记录首次置管当日身长(Ht_(1))以及PICC尖端位置、置管期间胸片检查当日身长(Ht_(n))以及PICC尖端位置,并计算相应的身长增长率。身长增长率与PICC尖端移位的相关性用Spearman秩相关分析。将AGA和SGA的身长增长率分别与PICC尖端移位进行简单线性回归分析,构建回归模型,用协方差分析比较两组回归直线。结果VLBW中AGA组97.8%患儿出现移位,SGA组所有的患儿都出现移位,占比最多的均为移位3个椎体。Spearman秩相关分析结果显示,两组患儿身长增长率与PICC尖端移位均具有相关性(AGA组rs=-0.719,P<0.001;SGA组rs=-0.769,P<0.001),随着VLBW身长增长,PICC尖端逐渐移位远离心脏。简单线性回归分析结果显示,AGA组回归模型(R^(2)=0.517,调整后R^(2)=0.513,F=129.487,P<0.001),SGA组回归模型(R^(2)=0.591,调整后R^(2)=0.585,F=95.385,P<0.001)。协方差分析结果显示,由于回归系数检验没有统计学意义,两条直线平行,说明身长增长率对两组患儿位移的影响一致。截距比较有统计学意义(F=9.265,P=0.003),说明两组患儿位移的起点不同(即增长率为零时的位移位置),说明位移与是否为AGA、SGA有关。结论随着VLBW中AGA和SGA身长增长,PICC尖端逐渐移位远离心脏,但相同的身长增长率,SGA引起的导管尖端移位幅度更大。建议AGA身长增长率12.4%、SGA身长增长率9.5%可作为监测导管尖端位置的重要时机,以免导管尖端进一步移位至非中心静脉,导致相关并发症发生。
