Effect Evaluation of Blinding Manipulation of Peripherally-inserted Central Catheter by Using the Carina as Evaluation Mark

ObjectiveTo evaluate tip location of peripherally inserted central catheter (PICC) by using the carina as evaluation mark, so as to provide clinical references for blinding manipulation of PICC. MethodsA retrospective analysis about the effects of tip location of PICC by using the carina as evaluation mark on inpatients with malignant tumour was conducted in tumour centre of the West China Hospital from March 2013 to April 2014. Chest X radiography was applied to evaluate the tip location of PICC. Statistical analysis was performed using SPSS software (version 19.0) and the outcomes were presented by frequency and percentage. ResultsA total of 612 cases of blinding manipulation of PICC were evaluated, of which, 502 (82%) were located in the central venous and 110 (18%) were located in the noncentral venous. The numbers of those with the catheter tips located in the non-central venous were 38 in the right atrium, 33 in the internal jugular vein, 24 in the innominate vein, 8 in the axillary vein, and 7 in the subclavian vein, respectively. ConclusionThe effects of blinding manipulation of peripherally-inserted central catheter by using the carina as evaluation mark are relatively good. But it still needs to be improved.

Clinical Efficacy of Central Venous Catheter Closed Drainage of Pleural Cavity Combined with Negative Pressure Suction for Spontaneous Pneumothorax: A Systematic Review and Meta-analysis

ObjectiveTo evaluate the clinical efficacy of central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax. MethodsThe randomized controlled trials(RCTs) on central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax were searched in PubMed, OVID, CNKI, Wangfang database, Super Star Digital Library, CMB, Baidu and Google search engines. The searching time was from the time of building database to September 15, 2014. Two searchers selected studies based on the included criteria strictly. The quality of RCTs was appraised by the criteria of Cochrane Collaboration. RevMan5.3 software was used for data analysis and management. ResultsA total of 18 RCTs including 1 549 patients were identified. There were no statistical differences in time of lung recruitment (SMD=0.01 and 95%CI -0.23 to 0.25, P=0.95), time of hospital stay (SMD=-0.42, 95%CI -1.81 to 0.97, P=0.55), curative resection rate (RR=1.04 and 95%CI 1.00 to 1.08, P=0.07) between the two groups. The rate of complications in the central venous catheter group was less than that in the conventional pleural cavity closed drainage group with a statistical difference (RR=0.31, 95%CI 0.23 to 0.43, P<0.000 01). ConclusionThe treatment of central venous catheter closed drainage of pleural cavity combined with negative pressure suction for spontaneous pneumothorax is a simple and safe operation. However, the quality of studies included is not high and some sample size is small. RCTs with large sample of high quality are still needed for further confirmation.

Implementation and Effects of Continuous Quality Improvement in the Care of Peripherally Inserted Central Catheter

ObjectiveTo evaluate the clinical effects of continuous quality improvement (CQI) in the care of peripherally inserted central catheter (PICC). MethodsWe retrospectively analyzed the clinical data of 40 patients who received PICC treatment in our hospital between January and December 2011, and then we found out the main problems of PICC catheter care, analyzed the related factors for complications of PICC, and formulated corresponding nursing countermeasures. PICC receivers between January and December 2012 were regarded as controls. Then, we compared the complication incidence and satisfaction of patients between the two groups before and after the implementation of CQI. ResultsAfter the implementation of CQI, complication incidence was significantly lower (P<0.05). The satisfaction degree of patients toward caring rose to 87.8%, which was statistically significant (P<0.05). ConclusionThe implementation of CQI is beneficial to reduce complications of PICC treatment, and patients'satisfaction rate is also significantly increased.

Establishment of risk factors and risk nomogram model for unplanned extubation during peripherally inserted central catheter retention in cancer patients

ObjectiveTo retrospectively analyze the causes and risk factors of unplanned extubation (UE) in cancer patients during peripherally inserted central catheter (PICC) retention, so as to provide references for effectively predicting the occurrence of UE. Methods27 998 cancer patients who underwent PICC insertion, maintenance and removal in the vascular access nursing center of our hospital from January 2016 to June 2023 were retrospectively analyzed. General information, catheterization information, and maintenance information were collected. The Chi-squared test was used for univariate analysis, multivariate analysis was used by binary unconditional logistic regression. They were randomly divided into modeling group and internal validation group according to the ratio of 7∶3. The related nomogram prediction model and internal validation were established. ResultsThe incidence of UE during PICC retention in tumor patients was 2.80% (784/27 998 cases). Univariate analysis showed that age, gender, diagnosis, catheter retention time, catheter slipping, catheter related infection, catheter related thrombosis, secondary catheter misplacement, dermatitis, and catheter blockage had an impact on UE (P<0.05). Age, diagnosis, catheter retention time, catheter slipping, catheter related infection, catheter related thrombosis, secondary catheter misplacement, and catheter blockage are independent risk factors for UE (P<0.05). Based on the above 8 independent risk factors, a nomogram model was established to predict the risk of UE during PICC retention in tumor patients. The ROC area under the predicted nomogram was 0.90 (95%CI 0.89 to 0.92) in the modeling group, and the calibration curve showed good predictive consistency. Internal validation showed that the area under the ROC curve of the prediction model was 0.91 (95%CI 0.89 to 0.94), and the trend of the prediction curve was close to the standard curve. ConclusionPatients aged ≥60 years, non chest tumor patients, catheter retention time (≤6 months), catheter slipping, catheter related infections, catheter related thrombosis, secondary catheter misplacement, and catheter blockage increase the risk of UE. The nomogram model established in this study has good predictive ability and discrimination, which is beneficial for clinical screening of patients with different degrees of risk, in order to timely implement targeted prevention and effective treatment measures, and ultimately reduce the occurrence of UE.
