ObjectiveTo explore the effectiveness of the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments to treat acute complete acromioclavicular dislocations. MethodsBetween January 2008 and April 2012, 66 patients with acromioclavicular dislocation were treated with the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments in 32 cases (experimental group) and with the clavicular hook plate in 34 cases (control group). There was no significant difference in gender, age, injured side, the cause of injury, and the time from injury to operation between 2 groups (P>0.05). Visual analogue scale (VAS), Constant shoulder scores, and coracoid clavi-cledistance (CC.Dist) were measured at preoperation and at 2 years after operation. Signal/noise quotiem (SNQ) was measured by MRI at 2 years after operation. The operation complications were observed. ResultsThe patients of 2 groups obtained primary healing of incision. The morbidity of complication in experimental group (12.5%, 4/32) was significantly lower than that in control group (91.2%, 31/34) (χ2=40.96, P=0.00). All the cases were followed up 2.8 years on average (range, 2 to 4 years). VAS scores and CC.Dist significantly decreased at 2 years after operation when compared with preoperative values in the 2 groups (P<0.05). VAS scores and CC.Dist of the experimental group were significantly lower than those in the control group (P<0.05). According to Constant shoulder scores at 2 years after operation, the results were excellent in 19 cases, good in 11 cases, and general in 2 cases with an excellent and good rate of 93.75% in the experimental group; the results were excellent in 7 cases, good in 8 cases, general in 16 cases, and poor in 3 cases with an excellent and good rate of 44.11% in the control group; and significant difference was shown between 2 groups (t=2.30, P=0.03). SNQ was significantly lower in experimental group than in control group at 2 years after operation (t=55.03, P=0.00), indicating that ligament healing was better in experimental group than control group. ConclusionCompared with simple clavicular hook plate fixation, the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments is successful in treating acute complete acromioclavicular dislocations, with the advantages of higher ligament healing, less complication, and early improvement of shoulder functions.
ObjectiveTo investigate the countermeasures for difficult removal of screws in the plate. MethodsThe clinical data were retrospectively analyzed from 47 patients having difficult removal of screws in the plate between January 2004 and May 2014. There were 30 males and 17 females, aged 16-58 years (mean, 34 years). The time from internal fixation to removal of internal fixation was 10 months to 20 years (mean, 22 months). The locations of internal fixation were upper extremity in 25 cases and lower extremity in 22 cases. The number of difficult removal screws in the plate was 1 in 18 cases, 2 in 15 cases, 3 in 9 cases, and 4 in 5 cases. The plate types included general plate in 15 cases and locking plate in 32 cases; stainless steel plate in 10 cases and titanium plate in 37 cases. The reason for difficult removal, plate, screw, incision, and bone quality of patient were comprehensively analyzed, and different methods for difficult removal were chosen according to the principle that first simply then complicated. ResultsAll plates and screws were removed, and no iatrogenic fracture or nerve and vascular injuries occurred. The operation time was 65-270 minutes (mean, 125 minutes). The blood loss was 80-775 mL (mean, 157 mL). The postoperative drainage was 20-250 mL (mean, 92 mL). The incision healing by first intention was obtained in 39 cases, and delayed healing in 8 cases. The patients were followed up 3-24 months (mean, 10 months). No infection or re-fracture was observed. ConclusionThere are many countermeasures for difficult removal of screws in the plate, but each has indication. As long as a well arranged preoperative condition, mastering a variety of methods, and being familiar with its indication, as well as reasonably choosing method based on the specific situations, the plate and screw maybe smoothly removed.

Objective To evaluate the effectiveness and safety of dexmedetomidine for postoperative sedation in cardiac patients. Methods Such databases as PubMed, EBSCO, Springer, Ovid, The Cochrane Library, CBM, CNKI, VIP and WanFang Data were searched electronically from the date of their establishment to May 2012, and other relevant journals and references of the included literature were also searched manually. Two reviewers independently screened the studies in accordance with the inclusion and exclusion criteria, extracted data and assessed methodology quality. Then the meta-analysis was performed using RevMan 5.1software. Results A total of 8 randomized controlled trials (RCTs) involving 1 157 patients were included. The Jadad scores of 7 RCTs were more than 3, and only 1 RCT scored 2. The results of meta-analysis showed that compared with the control group, dexmedetomidine significantly raised peripheral oxygen saturation (RR=0.90, 95%CI 0.31 to 0.49, P=0.003), decreased the incidence of average heart rate (RR=–5.86, 95%CI –7.31 to −4.40, Plt;0.000 01), ventricular tachycardia (RR=0.27, 95%CI 0.08 to 0.88, P=0.03), delirium (RR=0.28, 95%CI 0.16 to 0.48, Plt;0.000 01) and postoperative hyperglycemia (RR=0.57, 95%CI 0.38 to 0.85, P=0.006), and reduced the number of patients who needed vasoactive agents such as epinephrine (RR=0.53, 95%CI 0.29 to 0.96, P=0.04) and β-blocker (RR=0.60, 95%CI 0.38 to 0.94, P=0.03). However, it failed to shorten the time of both ICU stay (RR=−1.24, 95%CI −4.35 to 1.87, P=0.43) and mechanical ventilation (RR=−2.28, 95%CI −5.13 to 0.57, P=0.12), increase mean artery pressure (RR=−2.78, 95%CI −6.89 to 1.34, P=0.19), and well control postoperative nausea, vomiting and atrial-fibrillation. There were no significant differences between the two groups in myocardial infarction, acute cardiac failure, acute kidney failure, and mortality rate. Conclusion For postoperative sedation in cardiac patients, dexmedetomidine can effectively stabilize hemodynamic indexes, and reduce tachycardia, delirium, postoperative hyperglycemia and vasoactive agents. However, it has no marked influence on the prognosis. For the quantity and quality limitation of included studies, this conclusion needs to be proved by performing more high quality and large sample RCTs.
Objective To evaluate the relevant systematic reviews/meta-analyses that focused on the prevention and treatment of complications after impacted tooth extraction. Methods The systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction were searched in PubMed, The Cochrane Library, CBM, CNKI and WanFang Data from inception to September 30th, 2012, and a total of 15 professional journals and the references of included studies were also retrieved manually. Two reviewers screened the literature according to the inclusion criteria and extracted the data. Then the AMSTAR was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence. Results A total of twelve relevant systematic reviews/meta-analyses were included, of which five focused on the prevention and treatment of dry socket, six on the prevention of swelling, seven on the prevention and treatment of pain, six on the prevention of limitation of mouth opening, two on the prevention of infection, three on the prevention of bleeding, and one on the treatment of nerve damage after tooth extraction. Based on AMSTAR, seven studies were minor limitations and five studies were moderate limitations. Based on GRADE system, two was high quality of evidence, twelve were moderate, nine were low, and seven were very low. Conclusion Currently, the systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction can provide some references for clinical practice, which should be combined with the real condition by clinical doctors when making an evidence-based decision. However, it also suggests performing more high quality and large sample studies to prove this conclusion.
Objective To systematically evaluate the influence of PICC (peripherally inserted central catheter) ultrasound guidance on success rates and incidences of complications of elbow catheterization. Methods The Cochrane Library (Issue 3, 2012), Library of JBI evidence-based nursing center, MEDLINE, EMbase, CBM, VIP, CNKI and WanFang Data were searched for relevant studies to influence on success rates of puncture and catheterization and complications from upper arm placement of PICC ultrasound guidance as well as conventional PICC placement from inception to March, 2012. The data were extracted according to the inclusion and exclusion criteria by two reviewers, the quality of included studies was also evaluated. Meta-analysis was conducted using RevMan 5.1, or only descriptive analysis was conducted instead. Results Eleven randomized controlled trials, five clinical controlled trials and four cohort studies were included, involving 4 052 patients. The results of meta-analysis showed that, upper arm placement of PICC ultrasound guidance combined with modified Seldinger technique was associated with significantly higher one-time success rates of puncture and catheterization than conventional PICC placement below the elbow, with significant differences (OR=4.71, 95%CI 1.97 to 11.28, P=0.000 5; OR=8.63, 95%CI 1.92 to 38.82, P=0.005). Conventional elbow catheterization had a significantly higher incidence of phlebitis than catheterization on the elbow that under the guidance of PICC ultrasound and modified Seldinger technique (OR=0.13, 95%CI 0.08 to 0.21, Plt;0.000 01). Conclusion Elbow catheterization under the guidance of PICC ultrasound combined with modified Seldinger technique has an obvious advantage in improving the success rates of puncture and catheterization and reducing the incidence of complications, compared with conventional elbow catheterization.
