ObjectiveTo investigate the application and effect of quality control circle (QCC) in the management of hand hygiene for nurses in hemodialysis center. MethodsQCC was applied in the management of hand hygiene in hemodialysis center from March 2013 to February 2014. Factors affecting the compliance and correctness of hand hygiene in hemodialysis nurses were analyzed, and counter measurements were established and applied. Moreover, effect of QCC management was also assessed. ResultsAfter the application of QCC, the compliance and correctness of hand hygiene in hemodialysis nurses increased significantly from 41.02% to 88.46% (P<0.05) and 46.88% to 91.30% (P<0.05), respectively. Moreover, maneuver application, team spirit, professional knowledge, communication and cooperation among nurses were also increased by QCC management. ConclusionThe application of QCC can not only increase the compliance and correctness of hand hygiene in hemodialysis nurses but also improve team cohesiveness, which is worth recommendation and promotion.
ObjectiveTo investigate the effects of problem-intervention-outcome (P-I-O) teaching method on the normalization training of new nurses. MethodsA total of 101 new nurses from 2011 to 2013 were included in this research. Forty-two new nurses who were invited from August 2011 to July 2012 were distributed into group A, and 59 new nurses who were invited from August 2012 to July 2013 were distributed into group B. Both groups accepted normalization training. Group B accepted P-I-O teaching at the same time. We assessed the differences in operating, theory, attendance, the rates of harmful events and the degree of satisfaction between the two groups. ResultsTheory and operating between the two groups had significant differences (t=3.44, 2.86; P<0.05). Attendance, rates of harmful events and the degree of satisfaction all had significant differences between the two groups (t=2.94, χ2=8.45, Z=-2.05; P<0.05). ConclusionThe application of P-I-O teaching method in the normalization training of new nurses can stimulate their study interest and enthusiasm, transit their role faster, as well as reduce the rates of clinical harmful events and elevate the quality of care. Thus, it is worthy of being popularized in clinical nursing care.
Objective To discuss the imaging characteristics and clinical treatment methods of congenital biliary dilation. Methods Clinical data of 70 cases of congenital biliary dilation who treated in The Third Affiliated Hospital of Henan University of TCM and Henan Provincial People’s Hospital from Jan. 2010 to Jan. 2015 was collected and analyzed. Methods Along the bile duct region (all cases received ultrasound), the ultrasound of 57 cases (81.4%) showed irregular spherical, spindle, or prismatic area without echo connected to the proximal part of the bile duct, the intracavity wall of it was skin pass rolling, and part of it had the spotty detailed or slightly strong stones sound shadow, 1 case combined spindle or capsular area without echo connected to the intrahepatic bile duct partly and along with it. CT of 45 cases (64.3%, 43 cases were diagnosed as congenital biliary dilation) without and with enhancement scanning showed low-density and irregular oblate, cystiform, columniform or fusiform expansion shadow, slight mass effect, no difference before and after the enhancement of partial intrahepatic bile duct and choledoch, and that the structure of surrounding tissues were compressed, lapsed, and deformed. The MRI and magnetic resonance cholangiopancreatography (MRCP) inspection of 65 cases (92.8%, all of 65 cases were diagnosed as congenital biliary dilation) showed tadpole-shaped, irregular cystiform, columniform or fusiform expansion with long T2 and high MRCP signal shadow image of partial intrahepatic bile duct and choledoch, the dilated bile duct also being connected to biliary tree. Of the 70 cases, there were 66 cases (94.3%) of type Ⅰ, 1 case (1.4%) of type Ⅱ, 1 case (1.4%) of type Ⅳa, 2 cases (2.9%) of type Ⅳb. Sixty eight cases (65 cases of type Ⅰ, 1 case of type Ⅱ, 2 cases of type Ⅳb) underwent cholecystectomy+dilated bile ducts resection+common hepatic duct jejunum anastomosis (Roux-en-Y), 1 case underwent cholecystectomy+dilated bile ducts resection+pancreatic duodenal resection, another 1 case underwent cholecystectomy+dilated bile ducts resection+common hepatic duct jejunum anastomosis (Roux-en-Y)+resection of left hepatic lobe. All the cases were successfully recovered without severe complications and had no dead case, but 13 cases (18.6%) suffered from minor complications, including 6 cases of short-term abdominal pain and abdominal distension, 1 case of bile leak, 2 cases of incision infection, 3 cases of pulmonary infection, and 1 case of alteration of intestinal flora. All of the 70 cases were followed-up for 6-56 months (average of 36 months). During the follow up period, 2 cases died in reason of other incidence, 4 cases suffered from simple cholangitis, 3 cases suffered from cholangitis combined with intrahepatic bile duct stone, 2 cases suffered from cholangitis combined with intrahepatic bile duct stone, slight anastomotic stoma stenosis, and mild jaundice, 2 cases suffered from cholangitis. Conclusion Congenital biliary dilation has no typical clinical feature, but it has identifiable imaging manifestation, which can provide a theoretical foundation for congenital biliary dilation in diagnosing, preoperative evaluation, and chosing operative methods. Ultrasound is the first choice, MRI and MRCP are propitious to diagnose, locate, and classfy. The treatment of congenital biliary dilation is resecting the dilated bile ducts fully and performing the common hepatic duct jejunum anastomosis.
Objective To investigate the technique and effectiveness of modified laminoplasty for lumbar spinal stenosis (LSS) and to explore the application value of modified laminoplasty in maintaining the stability of the spine by comparing with the conventional laminectomy. Methods Fifty-six patients with LSS were included between June 2012 and July 2013, and they were divided into 2 groups: 27 patients underwent modified laminoplasty in group A, and 29 patients received conventional laminectomy in group B. There was no significant difference in sex, age, disease duration, narrow segment, visual analogue scale (VAS) score of low back pain and leg pain, Japanese Orthopaedic Association (JOA) score, and walking tolerance between 2 groups (P > 0.05). The postoperative VAS score of low back pain and leg pain, JOA score, walking tolerance, X-ray film, and CT were used to evaluate the clinical results. Results Dural tear occurred in 2 cases of group A and 1 case of group B and were repaired during operation. All incisions primarily healed without infection. The patients were followed up 24-31 months (mean, 24.7 months) in group A, and 24-37 months (mean, 26.2 months) in group B. The bone healing time was 6-12 months (mean, 9 months) in group A. CT showed healing at the junction of spinous process and vertebral plate in group A at 12 months after operation; new scar in varying degre es was observed in group B. At last follow-up, lumbar spondylolisthesis and instability occurred in 4 and 2 cases of group B respectively, and received re-operation. The change value of slip distance was (0.27±0.23) mm in group A and was (0.83±1.22) mm in group B, showing significant difference (t=-2.405, P=0.023). The postoperative JOA score, VAS score, and walking tolerance were significantly improved when compared with preoperative ones in 2 groups (P < 0.05). At last follow-up, group A was better than group B in VAS score of low back pain (P < 0.05), but no significant difference was found in the other indexes between 2 groups (P > 0.05). Conclusion The modified laminoplasty is better than the conventional laminectomy in relieving low back pain and maintaining the stability of the lumbar spine.
Objective To systematically evaluate the effect and safety of systemic corticosteroids for acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 6, 2015), Wanfang Data, CBM, CNKI were searched to collect randomized controlled trails (RCTs) about systemic corticosteroids for acute exacerbation of COPD from inception to July 2015. The meta-analysis was conducted using RevMan 5.3 software. Results A total of 11 RCTs involving 1298 patients were included. The results of meta-analysis showed that a statistically significant increase in the treatment success rate when using systemic corticosteroids (RR=1.11, 95%CI 1.01-1.21,P=0.02), and a non-significant difference of effect in the subgroup of emergency department and ICU patients (RR=0.98, 95%CI 0.90-1.08,P=0.74;RR=1.19, 95%CI 0.84-1.69,P=0.34). Conclusions Current studies suggest that systemic corticosteroids is beneficial in terms of treatment success rate, but subgroup analysis shows that this benefit is controversial in emergency department and ICU. however, due to the limited quantity of the included studies, the above conclusions still need more high quality research to be verified.
