ABSTRACT
The female infant in this case study was admitted to the hospital 4 hours after birth due to preterm birth and respiratory distress. On the third day after birth, peripherally inserted central venous catheter (PICC) catheterization was performed. On day 42, thrombus was found at the entrance of the right atrium from the inferior vena cava during a cardiac ultrasound, and it was considered to be related to PICC placement. Low-molecular-weight heparin and urokinase were given. After two weeks of treatment, ultrasonic monitoring showed thrombus shrinkage. No bleeding or pulmonary embolism occurred during the treatment. The patient discharged after improvement. This article mainly introduces a multidisciplinary team approach to diagnosis and treatment of PICC-related thrombosis in neonates.

Objective:To explore the application effect of segmented teaching combined with Kirkpatrick model evaluation in the teaching of specialized nurses of peripherally implanted central venous catheter (PICC).Methods:A total of 60 trainees in the PICC specialized nurse training class in PICC Clinic of Cancer Hospital Affiliated to Nantong University from June 2020 to September 2020 were selected in the study, and they were randomly divided into a control group and a study group, with 30 nurses in each group. The control group conducted traditional training for PICC specialized nurses, and the research group used segmented teaching. After training, the Kirkpatrick model was used to evaluate the response level, learning level, behavior level and result level of the training effect of the two groups of PICC specialized nurses. SPSS 22.0 was used for t test and chi-square test. Results:Through the segmented teaching training, the evaluation results of the Kirkpatrick model showed that the effect of the PICC specialized nurse training was significantly better in the study group than that in the control group in terms of response level, learning level, behavior level and result level. The study group's satisfaction with the training program and teaching content scored higher than that of the control group, with statistically significance ( P<0.001). The research group nurses' mastery of theoretical knowledge and practical skills and humanistic care scores were higher than those of the control group, with significant differences ( P<0.001). After the training, the self-behavior assessment scores of the two groups increased, and the improvement of the research group was more obvious. When the nurses of the research group returned to the hospital clinical work after training, their professional identity, PICC teaching and guidance ability, treatment, nursing service quality, the recognition of patient and family members and the effectiveness of the department were improved to varying degrees, the corresponding measures could be carried out in the hospital, and the development of PICC technology was promoted. Conclusion:The combination of segmented teaching and Kirkpatrick model evaluation can effectively meet the training needs of PICC specialized nurses and make a full range of effect evaluations to improve the quality of PICC specialized nursing services.
ABSTRACT
Objective@#To investigate the application of music intervention in combination with maternal voice during PICC placement procedures in malformation alimentary tract infants.@*Methods@#A total of 60 malformation alimentary tract infants were enrolled in the present study in Hunan Children Hospital from January to December 2018, infants were randomly assigned to the intervention group (n=30) and the control group (n=30). Patients in the control group received conventional nursing, the intervention group received music and maternal voice intervention method. The level changes of heart rate, respiratory rate, blood pressure, blood oxygen saturation and cortisol concentration were compared between two groups, meanwhile, the pain rating were assessed by Neonatal Infant Pain Scale (NIPS).@*Results@#Before procedure, no significant difference was found between the control and intervention group in heart rate, respiratory rate, systolic pressure, SpO2 and NIPS score (P>0.05). During and after the procedure, the mean heart rate [(144.43±15.93), (142.43±20.42) times/min], respiratory rate [(44.70±4.51) and (43.50± 4.12) times/min], systolic pressure [(87.40±8.53) and (86.10±4.60) mmHg] and NIPS score (5.34±0.71 and 5.19±0.87) of the intervention group was statistically lower compared to the control group [(160.97±39.35) and (159.17±31.87) times/min, (53.13±7.85) and (50.47±7.70) times/min, (97.60±9.82) and (94.27±7.23) mmHg, 6.17±0.54 and 6.15±0.66; during procedure, the mean SpO2 was statistically significantly higher, compared to the control group [(96.15±9.82)% versus (88.34±9.53)%]. The difference was statistically significantly (t=2.134-6.682, P<0.05). Before placement, the concentration of cortisol between the two groups showed no significant difference (P>0.05), and (208.91±21.07)ng/ml 5min after placement and (197.70±16.34) ng/ml immediately after placement, the cortisol concentration was statistically significantly lower, compared to the control group [(246.71±35.15), (230.95±21.81) ng/ml] (t=5.050-6.682, P<0.05). Compared with the control group, the time needed for PICC placement decreased remarkably in the intervention group [(15.62±3.30) min versus (24.63±4.26) min)](t=9.160, P<0.01).@*Conclusions@#Music in combination with maternal voice can significantly reduce stress levels, pain responses and time need for PICC placement, music and maternal voice is a potential intervention strategy in malformation alimentary tract infants undergoing PICC.
ABSTRACT
Objective@#To analyze the specificity and sensitivity of the modified microbubble test in identifying the peripherally inserted central venous catheters (PICC) tip based on the chest X-ray location as the "gold standard", and to find out an accurate and noninvasive PICC tip positioning method that can save time and cost.@*Methods@#Convenient sampling method was conducted. The patients under PICC guided by ultrasound in intensive care unit (ICU) or PICC clinic of the First Affiliated Hospital of Nanchang University from August 2017 to February 2018 were enrolled. All patients were followed up by ultrasound guided PICC catheter placement, modified microbubble test and chest X-ray localization. The relationship between the density of microbubbles in modified microbubble test and the location of PICC tip in chest X-ray localization was analyzed. Using chest X-ray localization as the "gold standard", the diagnostic evaluation indexes such as specificity and sensitivity of PICC tip identification by modified microbubble test were calculated.@*Results@#A total of 120 patients were enrolled during the study period, excluding those who refused to participate in the study, unclear right atrial ultrasound, conscious intolerance, unclear chest X-ray, and finally 108 patients completed the modified microbubble test and chest X-ray tip localization. According to the chest X-ray localization results of 108 patients, 69 patients (63.9%) were in ideal locations, 33 (30.6%) were in dissatisfactory position, and 6 (5.5%) were in malposition. There was no significant difference in gender, age, tube placement, depth of catheterization, placement of catheterization room, and catheterization among the three groups. In the modified microbubble test, there were 74 patients (68.5%) with gradeⅠmicrobubble, 25 (23.2%) with gradeⅡ microbubble, and 9 (8.3%) with grade Ⅲ microbubble. There was a correlation between microbubble density and the tip position of the catheter, showing a moderate intensity correlation, and the contingency coefficient was 0.662. The sensitivity of the modified microbubble test for PICC tip positioning was 95.7% (66/69), the specificity was 89.7% (35/39), the rate of missed diagnosis was 4.4% (3/69), the misdiagnosis rate was 10.3% (4/39), the positive predictive value was 94.3% (66/70), the negative predictive value was 92.1% (35/38), and the Youden index was 0.85. The consistency between the two methods was good, and the Kappa value was 0.86.@*Conclusions@#Compared with the chest X-ray localization method, the modified microbubble test method has high sensitivity and specificity in identifying PICC in the position, and the operation is simple, noninvasive, with less time and low cost. The modified microbubble test can be used as a screening test for PICC tip position, especially in ICU. When there are technical limitations or suspicious patient, further chest X-ray is necessary.

ABSTRACT
Objective To study the effect of nursing intervention on the catheter prolapse of the powerpPICC (high pressure injection type PICC catheter). Methods A total of 140 patients with powerpPICC were divided into observation group and control group by the catheter inserting time, with 70 cases in each group. The observation group received conventional nursing care, and the control group the targeted care measures based on analysis of catheter prolapse in the observation group. Result The rate of catheter prolapse in the observation group was significantly higher than that of the control group (P<0.05). Conclusions The prolapse of powerpPICC is related to catheter material, exposed length, fixed method, patient's compliance, catheter caring method. The care measures based on the different causes can decrease the rate of catheter prolapse and extend its duration.
ABSTRACT
<p>Objectives: Peripherally inserted central venous catheter (PICC) is widely used, because the incidence of complications and bloodstream infection in patients receiving PICC was lower than that in patients receiving central venous catheter. We compared PICC between cancer patients and non-cancer patients. Methods: This retrospective single-center study included 157 patients receiving PICC from May 2012 to September 2015. Patients were separated into cancer and non-cancer groups. Results: Cancer patients were 88 and non-cancer patients were 69. The most common causes of PICC were intravenous hyperalimentation (Cancer vs. non-cancer: 45 vs. 51) and difficult peripheral venous access (40 vs. 12) (p=0.0022). The duration of catheterization was 15 (6-39) vs. 21 (12-40) days (p<0.0001). The causes of catheter removal were death (50 vs. 14), remission (9 vs. 26), redness on insertion site or infection suspicion (10 vs. 11), and Some kind of catheter trouble (8 vs. 4) (p=0.0002). Complications occurred in 8 vs. 9 patients (p=0.429), and infection occurred in 0.9 vs. 2.0/1000 catheter days (p=0.041). Discussion: End-stage cancer patients have a weakened immune system. In this study, the incidences of PICC-related infection and other complications were not different between cancer and non-cancer patients, suggesting PICC was a safer method.</p>
ABSTRACT
Objective To analyze the relationship between the catheter to vein ratio and the formation of peripheral insertion of central venous catheter (PICC) related upper extremity deep venous thrombosis (PICC-UEDVT) in cases having undergone PICC in patients at intensive care unit (ICU) and further identify the best optimal ratio cut-off point to reduce the incidence of PICC-UEDVT.Methods A retrospective study was conducted, including 69 patients having undergone PICC with complete clinical data admitted to the Department of Critical Care Medicine of the First Affiliated Hospital of Nanchang University from August 2013 to December 2016; their ages were > 18 years old and catheter indwelling times were > 1 week; the patients' basic information, disease related laboratory parameters and catheter insertion situation were collected. According to the occurrence of PICC-UEDVT, they were divided into PICC-UEDVT group and non PICC-UEDVT group; the receiver operating characteristic (ROC) curve of the catheter to vein ratio versus the incidence ofPICC-UEDVT was plotted to assess the optimal ratio to reduce the incidence of PICC-UEDVT.Results In the 69 patients, there were 7 patients in the PICC-UEDVT group and 62 patients in the non PICC-UEDVT group, the incidence of PICC-UEDVT being 10.14%. Four, 5 and 6 French (Fr) catheters were indwelled in 43, 23 and 3 cases respectively, and the range of catheter to vein ratio was 20% - 67%. The comparisons between PICC-UEDVT group and non PICC-UEDVT group in various aspects were as follows: the incidence of DVT in the PICC-UEDVT group was significantly higher than that in non PICC-UEDVT group [42.9% (3/7) vs. 6.5% (4/62)], the rate of using vasopressor drugs [57.14% (4/7) vs. 17.74% (11/62)], D-dimer level [mg/L: 9.0 (3.0, 12.3) vs. 1.8 (1.0, 3.6)], patients of indwelling 5Fr catheter [71.4% (5/7) vs. 29.0% (18/62)] and the percentage of patientsapplying catheter to vein ratio 45%-67% [57.14% (4/7) vs. 17.74% (11/62)] in PICC-UEDVT group were all higher than those in the non PICC-UEDVT group, the differences being statistically significant (allP < 0.05). ROC analysis showed that the catheter to vein ratio 44% was the optimal cut off or critical point, the area under the ROC curve (AUC) at that point was 0.755, 95% confidence interval (95%CI) = 0.554-0.955, sensitivity = 71.4% and specificity = 79.0%; compared with the patients using 45%-67% catheter to vein ratio, the incidence of PICC-UEDVT was 6.182 times higher than those using the ratio 20%-44% [odds ratio (OR) = 6.182, 95%CI = 1.208-31.634,P = 0.036]; however, there was no significant difference in incidence of PICC-UEDVT between 20%-32% and 33%-44% (P = 1.000).Conclusion It is found that the 44% catheter to vein ratio was the optimal critical point to reduce the incidence of PICC-UEDVT, possessing relatively high sensitivity and specificity; applying <44% catheter to vein ratio can decrease the risk of PICC-UEDVT occurrence in patients at ICU.
ABSTRACT
Objective To study the effect of papaverine on vasospasm caused by PICC intubation with B-mode ultrasonography. Method Three mg papaverine were injected into the median cubital vein for at least 2 minutes in 15 patients with vasospasm. Results The vasospasm in the 15 patients was relieved 36~270 s seconds after injection. The followed intubation was all successful. There was no abnormality in their liver function and heart rate, or abnormal bleeding, or other serious complications. Conclusion Papaverine can relieve vasospasm caused by PICC intubation, so it can allow another intubation. It also can avoid delayed intubation reduce patients′pain and cost and reduce psychological pressure of the nursing practitioner.
ABSTRACT
Pericardial effusion with cardiac tamponade is a rare and life-threatening complication of peripherally inserted central catheter (PICC) in a neonate. We report a 33-week preterm neonate who had sudden clinical deterioration at day seven of total parenteral nutrition regime via PICC. Recognition of pericardial effusion with cardiac tamponade in neonates with a PICC requires a high index of suspicion and steps in prevention include proper catheter tip placement and continuous monitoring of line position and function.

ObjectiveTo explore the application of peripherally inserted central venous catheter (PICC)and central venous catheter (CVC) in the surgical parenteral nutrition.MethodThe operation time,success rate,indwelling duration,abnormal biopsy,and adverse reactions of PICC and CVC were retrospectively compared.ResultsCVC had significantly shorter operation time than PICC groups [ (28.67 ±5.13) min vs.(45.20 ±6.89)min,P =0.035 ).The mean indwelling duration was significantly longer in PICC group than in CVC group [ ( 114.85 ± 10.29) d vs.(24.78 ± 8.42) d,P =0.033 ].PICC group was superior to CVC group in terms of five complication items,while only phlebitis was more frequent/severe in CVC group.ConclusionsPICC may be more suitable for long-term ( ＞4 weeks) catheter-based nutrition.CVC has short operation time and fast flow rate,and therefore is most suitable for rescue treatment for critically ill patients.
ABSTRACT
Objective To evaluate the effectiveness of aspirin in preventing peripherally inserted central venous catheter (PICC) -related thrombosis. Methods Totally 360 cancer patients who had undergone routine PICC placement were equally randomized into aspirin group (receiving conventional PICC maintenance plus oral administration of aspirin; 100 mg/d, for consecutively 21 days) and control group (conventional PICC catheter maintenance). The incidences of phlebitis and thrombosis were observed in both two groups. Results The incidences of phlebitis and thrombosis were 3.3% and 0 in aspirin group, which were significantly lower than those in control group (8.9% , P = 0. 025; 1.7% , P = 0. 025). Conclusion The oral administration of aspirin after the PICC placement can reduce PICC-related thrombosis and phlebitis.
