ABSTRACT
BACKGROUND: Appropriate allocation of nursing staff is key to ensuring efficient nursing in hospitals, and is significantly correlated with patient safety, nursing quality, and nurse job satisfaction. However, there are few studies on nursing workforce allocation in the isolation wards of COVID-19 designated hospitals globally. This study aims to better understand the nursing workforce allocation in the isolation wards of COVID-19 designated hospitals in China, and provide a theoretical basis for efficiently deploying first-line nurses in China and across the world in the future. METHODS: An online survey was conducted among the head nurses (n = 229) and nurses (n = 1378) in the isolation wards of 117 hospitals (selected by stratified sampling), using a self-reported human resource allocation questionnaire. RESULTS: The average bed-to-nurse ratios of different isolation wards were different (Z = 36.742, P = 0.000). The bed-to-nurse ratios of the ICU, suspected COVID-19 cases ward, and confirmed COVID-19 cases ward, were 1:1.88, 1:0.56, and 1:0.45, respectively. The nurse work hours per shift in different isolation wards were also different (Z = 8.468, P = 0.014), with the specific values of the ICU, suspected COVID-19 cases ward, and confirmed COVID-19 cases ward, being 5, 6, and 6 h, respectively. A correlation analysis showed that the average work hours per shift was proportional to the overtime work of nurses (rs = 0.146), the proportion of nurse practitioners was proportional to the overall utilization rate of nursing human resources in the wards (rs = 0.136), and the proportion of nurses with college degrees was proportional to teamwork (rs = 0.142). The proportion of nurses above grade 10 was inversely proportional to teamwork and psychological problems (rs = 0.135, rs = 0.203). The results of multiple stepwise regression analyses showed that the work hours of nurses per shift was the main factor affecting nurse satisfaction and that the proportion of nurses and the work hours of nurses per shift were both independent factors affecting the length of stay (LOS) of patients. CONCLUSION: Hospitals in China have made good nursing workforce allocations during the COVID-19 pandemic, but there are certain shortcomings. Therefore, scientific and efficient nursing workforce allocation practice plans should be established to improve the ability of hospitals to deal with public health emergencies and are urgent problems that need to be addressed soon.
ABSTRACT
OBJECTIVES: To study the clinical value of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension of the newborn (PPHN). METHODS: A retrospective analysis was performed on the medical data of 11 neonates with PPHN who were treated with ECMO in the Neonatal Intensive Care Unit of Zhongshan People's Hospital from January 2015 to December 2021, involving the neonates' general information, clinical diagnosis, laboratory results, duration of ECMO treatment, complications during ECMO treatment, length of hospital stay, and outcome. RESULTS: Of the 11 neonates, 10 (91%) had successful weaning from ECMO, and 8 (73%) survived. For the 11 neonates, the mean duration of ECMO treatment was (81±50) hours (range: 26 to 185 hours), the mean duration of ventilator use was (198±105) hours (range: 57 to 392 hours), and the mean length of hospital stay was (22±15) days (range: 2 to 49 days). The oxygenation index and blood lactate level were significantly improved after 24 hours of ECMO treatment among the 11 neonates (P<0.05). Ten neonates had significantly reduced pulmonary artery pressure after 24 hours of ECMO treatment (P<0.05). One neonate had a progressive increase in the pulmonary artery pressure during EMCO treatment, succumbing to death. This neonate was diagnosed with alveolar capillary dysplasia based on the histopathological findings of the lung tissue and whole-exome sequencing results. Among the 11 children, 5 had intracranial hemorrhage, 1 had disseminated intravascular coagulation, 1 had gastric hemorrhage, 2 had pulmonary hemorrhage, 1 had renal insufficiency, and 3 had bleeding at the puncture site during ECMO treatment. CONCLUSIONS: ECMO is effective for the treatment of PPHN, however, the high incidence of complications of ECMO treatment suggests that it is important to carefully assess the indications and timing of ECMO treatment and improve the management of ECMO, which can improve the weaning rate and survival rate.

Although PD-1/PD-L1 immunotherapy has been used successfully in treating many cancers, metastatic colorectal cancer (CRC) patients are not as responsive. B7-H3 is a promising target for immunotherapy and we found it to have the highest expression among B7-CD28 family members in CRC. Thus, the aim of the present study was to investigate B7-H3 expression in a large CRC cohort. B7-H3, B7-H4, and PD-L1 protein levels and differential lymphocyte infiltration were evaluated in tissue microarrays from 805 primary tumors and matched metastases. The relationships between immune markers, patient characteristics, and survival outcomes were determined. B7-H3 (50.9%) was detected in more primary tumors than B7-H4 (29.1%) or PD-L1 (29.2%), and elevated B7-H3 expression was associated with advanced overall stage. Co-expression of B7-H3 only with B7-H4 or PD-L1 was infrequent in primary tumors (6.3%, 5.7%, respectively). Moreover, B7-H3 in primary tumors was positively correlated with their respective expression at metastatic sites (ρ = 0.631; p < 0.001). No significant relationships between B7-H4 and PD-L1 and survival were observed; however, B7-H3 overexpression in primary tumors was significantly related to decreased disease-free survival. A positive relationship between B7-H3 expression and high density CD45RO T cell was observed in primary tumors, whereas B7-H4 and PD-L1 overexpression were related to CD3 T-cell infiltration. In conclusion, compared with B7-H4 and PD-L1, B7-H3 expression exhibited a higher prevalence and was significantly related to aggressiveness, worse prognosis and CD45RO T-cell infiltration in primary tumors. Further exploration of this potential target of immunotherapy in CRC patients is warranted.

Objective: Meta-analysis to evaluate complications in the use of autogenous bone and bone substitutes and to compare bone substitutes, specifically HA, polyetheretherketone (PEEK) and titanium materials.Methods: Search of PubMed, Cochrane, Embase and Google scholar to identify all citations from 2010 to 2019 reporting complications regarding materials used in cranioplasty.Results: 20 of 2266 articles met the inclusion criteria, including a total of 2913 patients. The odds of overall complication were significantly higher in the autogenous bone group (n = 214/644 procedures, 33.2%) than the bone substitute groups (n = 116/436 procedures, 26.7%, CI 1.29-2.35, p < 0.05). In bone substitutes groups, there was no significant difference in overall complication rate between HA and Ti (OR, 1.2; 95% CI, 0.47-3.14, p = 0.69). PEEK has lower overall complication rates (OR, 0.51; 95% CI, 0.30-0.87, p = 0.01) and lower implant exposure rates (OR, 0.17; 95% CI, 0.06-0.53, p = 0.002) than Ti, but there was no significant difference in infection rates and postoperative hematoma rates.Conclusions: Cranioplasty is associated with high overall complication rates with the use of autologous bone grafts compared with bone substitutes. PEEK has a relatively low overall complication rates in substitutes groups, but still high infection rates and postoperative hematoma rates. Thus, autologous bone grafts should only be used selectively, and prospective long-term studies are needed to further refine a better material in cranioplasty.

OBJECTIVE: To evaluate the effect of proton pump inhibitors (PPIs) therapy on severe acute pancreatitis (SAP) patients. METHODS: Forty five patients with SAP recruited in our center from October 2015 to October 2016,were randomly assigned into two groups: convention group (C group,n=21) and convention+esomeprazole group (C+E group,n=24). C+E group received esomeprazole 40 mg/d intravenously for 1 week,whereas C group only received baseline treatment. Serum C-reactive protein (CRP),interleukin-6 (IL-6) and interleukin-8 (IL-8),tumor necrosis factor-α (TNF-α) and procalcitonin (PCT) were detected by ELISA on the first day (baseline) and the seventh day. Acute physiology and chronic health evaluation â ¡ scores (APACHE â ¡),systemic inflammatory response syndrome scores (SIRS) and modified Marshall scoring system (Marshall) were obtained at 1 d (baseline),3 d and 7 d. Upper gastrointestinal manifestation (peptic ulcer) and gastric pH were detected by endoscopic examination at 7 d. Fecal occult blood test was performed at 7 d. RESULTS: No significant difference was found in CRP,IL-6,IL-8,TNF-α and PCT between the two groups ( P>0.05),also no difference in APACHE â ¡,SIRS and Marshall scores ( P>0.05). The gastric pH was remarkably higher in C+E group when compared to C group (5.02±1.61 vs.2.83±1.08, P<0.001). There was no significant difference in the incidence of peptic ulcer and the rate of positive fecal occult blood between the two groups. CONCLUSION: PPIs therapy did not show benefit on alleviating systemic inflammatory response and clinical scores in SAP patients,and didn't improve the prevention of peptic ulcer and gastrointestinal hemorrhage.

BACKGROUND/AIMS: To longitudinally analyze changes of primary liver cancer incidence and mortality in mainland China during the first decade of 21st century. METHODOLOGY: Available data of crude incidence and mortality of primary liver cancer from annual reports of the National Central Cancer Registry in mainland China were retrieved and analyzed. RESULTS: Either the incidence or mortality of primary liver cancer in mainland China kept increasing and didn't reach peaks during the first decade of the 21st century, particularly among the female population with great incremental rates of incidence (8.76%) and mortality (11.99%) at 2007-2008 and 2009-2010, respectively. The crude incidence increased from 26.18/100,000 persons at 2004 to 29.00/100,000 persons at 2010, while the crude mortality from 25.08/100,000 persons to 28.10/100,000 persons (r=0.857, p=0.014). The incidence and mortality in males kept 2.5-2.9 folds to those in females. The incidence and mortality in rural region were always higher than those in urban regions, but among males both tended to decline in rural region, while in contrast increased in urban region. CONCLUSIONS: Liver cancer still has high incidence and mortality in mainland China, and further effort is required to prevent and control liver cancer, particularly for male and rural population.

PURPOSE: To prospectively evaluate the efficacy of a transjugular intrahepatic portosystemic shunt (TIPS) alone and TIPS in association with embolotherapy (TIPS+E) in the variceal coronary vein to prevent recurrent variceal bleeding and stent dysfunction after TIPS creation. MATERIALS AND METHODS: Institutional review board approval was obtained; all participants provided informed consent. A total of 106 patients (66 men, 40 women; age range, 18-70 years) with recurrent variceal bleeding due to hepatic cirrhosis were assigned randomly to the TIPS+E (n = 54) or TIPS (n = 52) group from May 2007 to July 2011. The TIPS was created by using covered stents. Patients in the TIPS+E group underwent embolotherapy via the jugular vein before TIPS implantation. Rates of recurrent variceal bleeding, stent patency, and survival were evaluated. Scores for liver function and life quality were calculated. RESULTS: TIPS placement was successful in all patients. Recurrent variceal bleeding ranked second among causes of death after TIPS placement. Although the 3-year cumulative rates of shunt patency, recurrent variceal bleeding, and survival in the two groups were not significantly different (P > .05), the 6-month overall rate of shunt patency in the TIPS+E group was significantly higher than that in the TIPS group (96.2% vs 82.0%, P = .019), and the 6-month overall rate of recurrent variceal bleeding was also significantly lower than that in the TIPS group (5.7% vs 20.0%, P = .029). CONCLUSION: The TIPS+E regimen may reduce the risk of recurrent variceal bleeding during the first 6 months after the TIPS procedure by preventing shunt dysfunction, which may improve liver function and quality of life. © RSNA, 2013.

AIM: To explore the nursing workforce allocation in intensive care units (ICUs) of COVID-19-designated hospitals during the epidemic peak in China. DESIGN: A nationwide cross-sectional online survey. METHODS: A total of 37 head nurses and 262 frontline nurses in 37 ICUs of COVID-19-designated tertiary hospitals located in 22 cities of China were surveyed. The self-reported human resource allocation questionnaire was used to assess the nursing workforce allocation. RESULTS: The average patient-to-nurse ratio was 1.89 ± 1.14, and the median working hours per shift was 5 h. The top four majors of front-line nurses in ICUs were respiratory (31.30%), lemology (27.86%), intensive care (21.76%) and emergency (17.18%). We also found that a smaller average patient-to-nurse ratio (odds ratio [OR]: 0.328, 95% CI: 0.108, 1.000), longer average weekly rest time per person (OR: 0.193, 95% CI: 0.051, 0.729) and larger proportion of 6-9 working years (OR: 0.002, 95% CI: 0.001, 1.121) decreased the occurrence of nursing adverse events.

OBJECTIVE: To establish a practical and effective clinical pathway (CP) for the etiological diagnosis of acute biliary pancreatitis. METHODS: A total of 2216 patients enrolled were randomly divided into control group (n = 1120) and CP group (n = 1096) according to different etiological diagnosis methods including following doctor's established experiences and habits and the designed CP in our study. RESULTS: There was no significant difference in baseline data between the two groups. The etiology of acute pancreatitis was determined in 91.1% (999/1096) of cases in the CP group which was significantly higher than the control group (65.5%, 734/1120), P < 0.05. The enhanced etiological determination of CP group was mainly consisted of the increased detection of biliary stones, duodenal diseases as well as pancreas divisum, P < 0.05. The positive etiological determination of magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography in the CP group were 59.1% (273/462) and 86.0% (98/114), respectively. CONCLUSIONS: The CP established in this study significantly enhances the biliary etiological determination of acute pancreatitis. It is easy to be conducted and may be of importance to improve the quality of etiological diagnosis of acute pancreatitis.

Objective: The purpose of this study was to analyze the techniques used to resection cervical extra-intraspinal neuromas (also known as cervical dumbbell neuromas) through the enlarged intervertebral foramen. Methods: A total of 34 consecutive patients (19 male, 15 female) with cervical dumbbell neuromas reviewed retrospectively between April 2008 and May 2020. Sixteen tumors were found in the intervertebral foramen of C1-C3, four in C3-C4, and 14 in C4-T1. The approach in all cases was to expose the tumors by intermuscular dissection and to remove them through the enlarged intervertebral foramen without excision of any bony structures. However, to expose tumors at different locations, the incisions shall be made accordingly. In this case series, the incisions were made along the posterior border of the sternocleidomastoid muscle for the C1-C3 tumors and along the anterior border of the muscle for the C3-C4 tumors. Transverse incisions were required for the C4-T1 tumors. Results: Following the mentioned incising approach, all 34 tumors were completely exposed. 31 were completely removed in one stage, and 3 tumors underwent subtotal resection because of brachial plexus nerve adhesion. The vertebral artery and spinal cord were undamaged for all cases. The patients who had total tumor resection showed no sign of recurrence on enhanced magnetic resonance imaging during follow-ups. The status of patients who underwent subtotal resection was stable after radiation therapy. None of the patients developed spinal instability. Conclusions: Cervical dumbbell neuromas can be exposed and removed through the enlarged intervertebral foramen without causing spinal instability or injury to the spinal cord or vertebral artery. This operative approach can retain the integrity of the structures of spine and should be considered the ideal approach for cervical dumbbell neuromas.
ABSTRACT
The accurate determination of the risk of cancer recurrence is a critical unmet need in managing thyroid cancer (TC). Although numerous studies have successfully demonstrated the use of high throughput molecular diagnostics in TC prediction, it has not been successfully applied in routine clinical use, particularly in Chinese patients. In our study, we objective to screen for characteristic genes specific to PTC and establish an accurate model for diagnosis and prognostic evaluation of PTC. We screen the differentially expressed genes by Python 3.6 in The Cancer Genome Atlas (TCGA) database. We discovered a three-gene signature Gap junction protein beta 4 (GJB4), Ripply transcriptional repressor 3 (RIPPLY3), and Adrenoceptor alpha 1B (ADRA1B) that had a statistically significant difference. Then we used Gene Expression Omnibus (GEO) database to establish a diagnostic and prognostic model to verify the three-gene signature. For experimental validation, immunohistochemistry in tissue microarrays showed that thyroid samples' proteins expressed by this three-gene are differentially expressed. Our protocol discovered a robust three-gene signature that can distinguish prognosis, which will have daily clinical application.

OBJECTIVE: The clinical diagnosis and surgical management of intramedullary spinal cord cavernous angioma were discussed. METHOD: Total 19 patients with intramedullary cavernous angioma were analyzed retrospectively on the clinical manifestation, radiographic feature, diagnosis and differentiation, surgical technique and caution. Of all the 19 patients, averaging 38.7 years old, 14 were male and 5 were female. Nine patients were followed. RESULT: All the 19 patients pathologically diagnosed with spinal cord cavernous angioma got good surgical results, besides one patient showed loss of proprioception. Nine patients were followed up and all demonstrated improvement on neurological function. CONCLUSION: The clinical symptom of most of the patients with spinal cord cavernous angioma presented mildly at onset, but deteriorated gradually because of repeated prehemorrhage. Since the lesion showed some characteristic in MRI, MRI examination was regarded as an important diagnostic tool. Dissection should be done between the tumor and the gliosis during the surgical procedure, special attention should be paid to avoiding tumor residual. It was not necessary to aggressively evacuate the hematoma derived from tumor hemorrhage, which extended along the central canal up and down, except obvious occupied syndrome exited.

OBJECTIVE: In some hospitals an adult colonoscope is used for colon examination in children because they do not have child colonscope equipment. This has some disadvantages and this paper reports the experience for colon examination in children with an adult gastroscope instead of an adult colonoscope. METHODS: One hundred and three children aged from 1.3 to 14 years who required routine colon examination were randomly assigned to adult gastroscope (n=49) and adult colonoscope groups (n=54). RESULTS: There were no significant differences in the success rate of implantation into the ileocecum between the gastroscope and colonoscope groups (93.9% vs 94.4%; P>0.05). The average time of implantation into the ileocecum in the gastroscope group was shorter than that of the colonoscope group (5.2+/-1.1 min vs 7.3+/-2.9 min; P<0.05). Seventeen patients showed implantation-related complications in the colonoscope group but only 5 patients in the gastroscope group (P<0.01). CONCLUSIONS: An adult gastroscope appears to be safer and more feasible than an adult colonoscope for colon examination in children.

BACKGROUND AND OBJECTIVE: The benefit from adjuvant chemotherapy for patients treated with neoadjuvant chemoradiotherapy (NCRT) and curative surgery remains controversial, particularly among those responding well to NCRT. This retrospective study aimed to clarify the benefits of adjuvant chemotherapy in terms of the oncological outcomes of patients with ypT0-2N0 rectal cancer after NCRT and curative surgery. METHODS: All patients with ypT0-2N0 rectal cancer after NCRT and curative resection between 2005 and 2014 were examined. The oncological outcomes between patients treated with adjuvant chemotherapy and those without any chemotherapy were compared. RESULTS: The clinicopathological characteristics of 110 patients were reviewed in this study; one patient was excluded due to lack of follow-up. Of the 109 patients included, 58 (53.2%) underwent adjuvant chemotherapy (chemo group), whereas the remaining 51 (46.8%) did not receive any chemotherapy (non-chemo group). After a median follow-up of 50 months, there were no significant differences in the 5-year overall survival (OS) or recurrence-free survival (RFS) rates between the groups (OS: 92.1 vs 86.3%, P = 0.375; RFS: 80.9 vs 74.7%, P = 0.534). Subgroup analysis also demonstrated no significant differences in 5-year OS and RFS rates between patients with ypT0N0 rectal cancer (P = 0.712 and P = 0.599, respectively) and those with ypT1-2N0 disease (P = 0.255 and P = 0.278, respectively). CONCLUSIONS: These results indicate that patients with ypT0-2N0 rectal cancer after NCRT followed by curative surgery may not derive significant benefit from adjuvant chemotherapy. However, further prospective randomized trials, with larger sample sizes, are warranted to confirm this conclusion.
ABSTRACT
Recurrence of hepatocellular carcinoma (HCC) after transarterial chemoembolisation (TACE) is common due to neoangiogenesis. Cyclooxygenase-2 inhibitors and somatostatin analogues were reported to inhibit tumour angiogenesis. The pilot randomized controlled trial was aimed to prospectively evaluate the protocol of TACE combined with celecoxib and lanreotide (TACE+C+L) in patients with unresectable and advanced HCC. A total of 71 patients with HCC were enrolled and randomly assigned to either TACE (n=35) or TACE+C+L (n=36) group. Overall survival, disease control rate (DCR), and adverse events were assessed during a 3-year follow-up period. The median overall survival of the TACE+C+L group (15.0 months) was doubled compared to that of TACE group (7.5 months), p = 0.012. DCR of the TACE+C+L group was significantly higher than that of the TACE group either at 6 months (72.2% vs 42.9%, p = 0.012) or at 12 months (61.1% vs 28.6%, p = 0.006). The median overall survivals (13 months vs 4.5 months, p = 0.013) and DCR at 12 months (50% vs 13.6%, p = 0.008) of patients with advanced HCC in TACE+C+L groups were significantly higher than those in TACE group. No significant difference of adverse events was observed between the two groups. The occurrence of post-embolisation syndrome in TACE+C+L group was significantly lower than that in TACE group (16.7% vs 60.0%, p = 0.001). In conclusion, the regimen of TACE+C+L prolonged overall survival, enhanced tumour response, reduced post-embolisation syndrome and was well-tolerable in the patients with unresectable HCC. It may be more beneficial for advanced HCC.

UNLABELLED: To study the androgen dependence of the neurotransmitter, calcitonin gene-related peptide (CGRP) in rat penis. METHODS: Forty-four Sprague-Dawley rats were randomly divided into Group A (intact controls), Group B (castrated) and Group C (gavaged with finasteride 4.5 mg.kg(-1).day(-1)). Four and ten weeks later respectively, half of rats in each group were anaesthetized. Blood samples were taken for the measurement of serum testosterone and dihydrotestosterone (DHT) by means of radioimmunoassay. Penile samples were harvested for the investigation of calcitonin gene related peptide (CGRP)-immunoreactive nerve fibers with immunohistochemistry. The computer-assisted imaging analysis system was applied to calculate the area proportion of the CGRP-positive nerve fibers (CGRP-PNF) in each group. RESULTS: 1) Both 4 and 10 weeks later, testosterone and DHT levels in Group B decreased significantly compared with those in Group A, (P <0.05, P <0.01, respectively); DHT level in Group C was also significantly decreased in comparison with that in Group A for both 4- and 10- week animals (P <0.05); 2) There was no significant differences in area proportion of CGRP-PNF among Groups A, B and C 4 weeks after treatments (P >0.05); However, 10 weeks later, the proportion of CGRP-PNF in Groups B and C was significantly less than that in Group A (P <0.01); 3) The proportion of CGRP-PNF of 4-week animals in Groups B and C was significantly higher than that of 10-week animals (P <0.05). CONCLUSION: The expression of neurotransmitter, CGRP may depend on androgens, including testosterone and DHT in rat penis.

A prospective randomized, controlled, single-blinded trial to compare the effectiveness and safety of heparin saline (HS) to those of normal saline (NS) as flushing and locking solutions for peripheral venous catheter (PVC) in decompensated liver cirrhosis (DLC) patients.Patients with DLC at our institution between April 2012 and March 2013 were enrolled after obtaining informed consent. The patients were randomly allocated into 2 groups: the NS group received preservative-free 0.9% sodium chloride as the flushing and locking solution, while the HS group received HS (50âU/mL). PVC-related events and the duration of PVC maintenance were compared between the 2 groups. Moreover, the preinfusion and postinfusion levels of prothrombin time (PT), activated partial thromboplastin time (APTT), and platelet (PLT) were also compared.A total of 32 and 36 DLC patients in the NS (125 PVCs) and HS (65 PVCs) groups, respectively, were analyzed. Baseline characteristics, including gender, age, Child-Pugh grade, PVC type and administration of anticoagulant, and irritant agents, were comparable between the 2 groups (Pâ>â0.05). The maintenance times of the HS and NS groups were 80.27â±â26.47 and 84.19â±â29.32âhours, respectively (Pâ=â0.397). Removal of PVC for abnormal reasons occurred in 30.7% and 22.4% of patients in the HS and NS groups (Pâ=â0.208). The PVC occlusion rates were 6.2% and 5.6% in the HS and NS groups, respectively (ORâ=â1.11, 95% CI 0.31-3.92). The PT, APTT, and PLT levels were comparable between the 2 groups both before and after infusion (Pâ>â0.05). Incremental analyses showed that Child-Pugh grade C might be a risk factor for the suppression of PLT in the HS group.We consider NS to be as effective as and safer than conventional HS for flushing and locking PVC in decompensated liver cirrhosis patients.

BACKGROUND AND AIM: In Mainland China, heparin saline solution is commonly used for flushing and locking peripheral intravenous access devices in clinical practice for a long time. We conducted a prospective controlled trial to compare the effectiveness and safety of preservative-free 0.9% sodium chloride solution versus heparin saline solution as flushing and locking solution for peripheral intravenous access devices. METHODS: Patients with gastroenterological or hepatic diseases were enrolled for this study from August 2011 to October 2011. After non-randomized allocation, preservative-free 0.9% sodium chloride was used as flushing and locking solution in the sodium chloride solution group, while hepatic solution (10 U/mL) was given in the heparin saline solution group. The device related complications and its maintenance duration were compared between two groups. One-way ANOVA, Chi(2), or Mantel-Haenszel test were performed using SPSS 13.0 and RevMan 5.0. RESULTS: Totally, 181 and 178 peripheral intravenous access devices in the sodium chloride solution and heparin saline solution groups were included and analyzed. Results indicated than sodium chloride solution did not increase the risks of occlusion (7.7% vs. 7.9%) and other adverse events of peripheral intravenous access devices (P = 0.163). Sodium chloride solution neither shortened the duration of peripheral intravenous access devices maintenance (3.6 ± 1.1 days vs. 3.7 ± 1.2 days, P = 0.651), nor increased the proportion of abnormal withdrawal (29.3% vs. 31.5%, P = 0.654). CONCLUSION: Sodium chloride solution is as effective and safe as conventional heparin saline solution for flushing and locking peripheral intravenous access devices, which results from our evidence-based study and should be transferred to other nurses in China.
