Abstract: Objective To investigate the method of improving effect, by investigating and analyzing the possible risk factors affecting shortterm outcome after total correction of tetralogy of Fallot (TOF). Methods Data of 219 patients who received total correction of TOF were divided into two groups according to the length of postoperative stay in hospital and recovery of heart function in the near future. Group A(n=110): patients had good recovery of heart function classified as gradeⅠorⅡ（NYHA classification）, and could smoothly be discharged from the hospital within two weeks without serious complications. The left ventricular ejection fraction (LVEF) had to exceed to 0.50 during 6 months followup visit. Group B(n=109): patients had worse recovery of heart function classified as grade Ⅱ or Ⅲ, and could not be discharged within two weeks with severe complications. LVEF was less than 0.50 during 6 months followup visit. The clinical data of two groups were compared, and risk factors affecting shortterm outcome after total correction of TOF operation were analyzed by logistic regression and model selection. Results There were good recovery of heart function classified as gradeⅠorⅡ(NYHA classification）in discharge, no death, and LVEF all exceeded to 0.50 in group A; there were 8 deaths in group B (7.34 %), and recovery of heart function was worse classified as grade Ⅱ or Ⅲ, with LVEF being less than 0.50（Plt;0.01）. Amount of postoperative daily thoracic drainage, assisted respiration time, time of inotropic agent stabilizing circulation, and the average length of postoperative stay in group A were all less or short than those in group B（Plt;0.01）. But the bypass and clamping time of group B were exceeded group A. The ratio of patching astride annulus in group B was greater than that in group A, and Nakata index was less than that in group A(Plt;0.01). The results of logistic regression and model selection indicate: age at repair (OR=0.69), oxygen saturation(OR=0.98), haematocrit before operation (OR=0.94), and patching astride annulus (OR=46.86), Nakata index (OR=16.90), amount of postoperative daily thoracic drainage (OR=0.84), presence of arrhythmia(OR=0.87), and wound infection(OR=63.57) have significant effect with shortterm outcome after total correction of TOF operation. Conclusions The probable methods to improving effect of shortterm outcome after total correction of TOF are an earlier age at repair, decreasing haematocrit, rising oxygen saturation before surgery, performing a palliative operation facilitating development of arteriae pulmonalis in earlier time, improving the surgical technique, and strengthening the perioperative care.
ObjectiveTo investigate the operation and effect of pressure ulcers group (PUG) on the procedure of clinical management of pressure ulcers. MethodsThe in-hospital patients with high-risk pressure ulcers and patients with pressure ulcers from outside of the hospital (n=145) before the founding of PUG in 2011 were regarded as group A, and patients in this group were treated by traditional therapies. After PUG was founded in our hospital in January 2012, 192 patients with high-risk pressure ulcers and from outside of the hospital in 2012 were considered as group B. In addition, group C contained 380 patients treated in 2013. Group B and C were both treated by PUG that developed a management system of pressure ulcers and took active measures to control and prevent pressure ulcers. PUG trained 30 clinical nurse supervisors, who were recommended from relevant clinical departments. The incidence of inevitable pressure ulcer of hospitalized patients, the cure rate of patients with pressure ulcers from outside of the hospital, pressure ulcer knowledge level of clinical nurse supervisors were comparatively analyzed between group A and B, and between group A and C, respectively. ResultsAfter the establishment of PUG, the incidence of inevitable pressure ulcer of hospitalized patients in group A, B, and C was 76.20%, 17.02%, and 14.61%, respectively. The cure rate of patients from outside of the hospital was 54.84%, 86.84%, and 87.97%, respectively. Differences between group A and B, and between group A and C both were significant (P<0.01). The pressure ulcer knowledge level of all nurse supervisors improved significantly (P<0.001). ConclusionThe establishment of PUG makes the clinical pressure ulcer management more scientific and objective. Furthermore, it can effectively reduce the incidence of pressure ulcers, and also improve the quality of medical care and ensure the safety of patients.

Objective To evaluate the results of operative treatment of acetabular fractures and to investigate its influence factors. Methods The cl inical data were analyzed retrospectively from 82 patients with acetabular fractures treated between September 2004 and June 2009. Of 82 patients, 65 were male and 17 were female, aged 26-72 years (mean, 38 years).Fractures were caused by traffic accident in 62 cases, by crush in 13 cases, and by fall ing from height in 7 cases. The time from injury to admission was 30 minutes to 12 days (median, 7.6 hours) in 70 cases, 12 cases were transferred because poor result after 34-67 days of conservative treatment. According to Judet classification, there were 24 cases of posterior wall fracture, 3 cases of posterior column fracture, 1 case of anterior wall fracture, 2 cases of anterior column fracture, 6 cases of transverse fracture, 16 cases of transverse and posterior wall fracture, 4 cases of posterior column and posterior wall fracture, 5 cases of T-type fracture, 3 cases of anterior and posterior hemitransverse fracture, and 18 cases of complete both-column fracture; 24 cases combined with dislocation of the hip. During operation, Kocher-Langenbeck approach was used in 49 cases, anterior il ioinguinal approach in 19 cases, and the combination of anterior and posterior approaches in 14 cases. Reconstructive plate (74 cases) and hollow lag screw (8 cases) internal fixation were used. The function of the hip was evaluated according to the modified Merled’Aubigne- Postel hip score system postoperatively. According to fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hi p dislocation and time of reduction, operative approach, deep vein thrombosis (DVT), and heterotopic ossification (HO), the patients were divided into the groups and the results were compared. Results Accordancewith the Matta X-ray evaluation criteria, anatomic reduction was achieved in 21 cases, good reduction in 37 cases, fair reduction in 16 cases, and poor reduction in 8 cases, and the excellent and good rate was 71%. All the cases were followed up 12-52 months mean, 34 months). Iatrogenic sciatic nerve injury occurred in 8 cases, infection in 3 cases, HO in 16 cases, DVT in 3 cases, hip posttraumatic arthritis in 12 cases, and avascular necrosis of the femoral head in 9 cases. X-ray examination showed that 80 cases achieved fracture union at 10-24 weeks after operation (mean, 14 weeks) and 2 cases had fracture delayed union at 10 months and 12 months after operation. According to the modified Merled’Aubigne-Postel hip score system, the function of the hip was rated as excellent in 26 cases, good in 32, fair in 20, and poor in 4 at 6 months after operation; the excellent and good rate was 71%. The affecting factors of cl inical results of acetabular fractures were fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hip dislocation and time of reduction (P lt; 0.05). However the operative approach, DVT, and HO were not affecting factor of the acetabular fractures (P gt; 0.05). Conclusion Operative treatment of acetabular fractures has a satisfying therapeutic effect. Fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hip dislocation, and time of reduction are risk factors affecting postoperative results.
ObjectiveTo explore the effect of doctor-nurse-patient communication area established in the ward. MethodsBefore (July to September 2013) and three months after (October to December 2013) the establishment of doctor-nurse-patient communication area, 30 doctors, 30 nurses and 216 patients or their family members were respectively investigated by questionnaires and interviews, and the data were collected and compared by t test. ResultsThirty questionnaires for doctors, 30 for nurses and 216 for patients or their family members were issued before and after the establishment of doctor-nurse-patient communication area. The response rate for the questionnaires was 100%. After the implementation of doctor-nurse-patient communication area, the satisfaction of patients' family members, nurses' awareness of the patients' condition and implementation of health education were significantly higher than those before the implementation (P < 0.05). ConclusionThe doctor-nurse-patient communication area established in the surgical ward can promote the trust between the patients and medical staff, create a good atmosphere to understand the needs of patients, meet patients' demand as far as possible and improve communication ability of medical staff, which makes doctors, nurses and patients more satisfied.
ObjectiveTo explorethe method and effectivenessofarthroscopically assisted treatmentof rotator cuff injury. MethodsBetween November 2009 and March 2011, 27 patients with rotator cuff injury were treated. There were 17 males and 10 females with a mean age of 43.6 years (range, 29-66 years). The disease duration was1 to 36 months (mean, 27months). The location was theleft shoulder in 11 cases and theright shoulder in 16 cases. Of them, 12 cases had a history of trauma and 15 caseshad no obvious predisposing causes. All patients had limitation of shoulder flexionandabduction. Anteroposterior and lateral X-ray films of the shoulder and the out-let X-ray films of the supraspinous muscle were taken. According to the acromion classification of Bigliani, there were 5 cases of type I, 13 cases of type II, and 9 cases of type III. MRI images showed all patients had rupture of the rotator cuff. The examination of shoulder arthroscope showed complete rupture of the supraspinatus muscle in 27 cases and acromion impingement in 23 cases. The patients without impingement underwent tear debridement, and the patients with impingement underwent acromioplasty and resection of subacromial bursa after tear debridement. The 3-4 cm incision was made with arthroscopically assisted positioning, and the metal suture anchorwas placed on the greater tubercle of humerus to repair rotator cuff. ResultsAll incisions healed primarily. All patients were followed up 13-27 months (mean, 19 months). No infection, loosening of internal fixation, and rotator cuffre-tearoccurred. Pain was relieved and the results was satisfactory after operation. The shoulder range of motion (ROM) at last follow-up was significantly improved when compared with preoperative ROM (P lt; 0.05). The visual analogue scale (VAS) score was significantly improved from 8.0 ± 1.8 at preoperation to 1.6 ± 0.7 at 2 weeks after operation and 0.8 ± 0.7 at last follow-up (Plt; 0.05); the University of California Los Angeles (UCLA) score of shoulder was significantly increased from 18.8 ± 6.6 at preoperation to 32.2 ± 3.3at 3months after operation and 33.6 ± 2.1 at last follow-up (P lt; 0.05). Conclusion The effectivenessofarthroscopically assisted treatmentof rotator cuff injury is satisfactory. However, long-termeffectiveness needs furtherfollow-up observation.
ObjectiveTo observe effect and safety of interstitial chemotherapy with 5-fluorouracil sustained release agent in radical operation of colorectal cancer. MethodsOne hundred and sixty patients with colorectal cancer from October 2011 to December 2013 were randomly divided into observation group and control group according to an incomplete random method, 78 cases of them were in the observation group and 82 cases of them were in the control group. All the patients were performed radical resection of colorectal cancer. The abdominal cavity and pelvic cavity were washed after surgery. 5-fluorouracil sustained release agent was implanted in the observation group patients for interstitial chemotherapy, the implant site was at the tumor resection area and the mesenteric artery. Routine chemotherapy was performed in these two groups after operation. The postoperative complications were observed. The postoperative local recurrence rate, liver metastasis rate, and 24-month survival rate were recorded. ResultsThe rates of abdominal complications and toxic effects had no significant differences between these two groups (P > 0.05). The rates of 12-month and 24-month local recurrence and the rate of liver metastasis in the observation group were significant lower than those in the control group[1.3% (1/78) versus 8.5% (7/82), x2=8.934, P=0.023; 5.2% (4/78) versus 23.2% (19/82), x2=14.834, P=0.004; 10.3% (8/78) versus 18.3% (15/82), x2=12.034, P=0.016]. The rate of 24-month survival in the observation group was significant higher than that in the control group[94.9% (74/78) versus 84.1% (69/82), x2=11.465, P=0.010]. ConclusionThe good safety of interstitial chemotherapy with 5-fluorouracil sustained release agent could effectively decrease local recurrence rate and liver metastasis rate of colorectal cancer after radical operation and improve survival time of patients.
ObjectiveTo investigate the feasibility and safety of the double cavity casing negative pressure drainage by inside and outside of the intestine in the primary resection and anastomosis of left colon cancer combined with acute obstruction. MethodsEighty-one cases of left colon cancer combined with acute obstruction who underwent surgeries in our hospital from January 2009 to December 2012 were collected prospectively, and were divided into one-stage surgery group (n=41) and control group (n=40). Cases of one-stage surgery group received double cavity casing negative pressure drainage by inside and outside of the intestine in the primary resection and anastomosis, and cases of control group underwent two-stage surgeries. Comparison of operation time, blood loss, time of anal exhaust after operation, hospital stay, hospital expense, and incidence of complication between the 2 groups was performed. ResultsThere were no significant difference in the operation time[(166±19) minutes vs. (173±23) minutes], blood loss[(253±42) mL vs. (273±50) mL], and time of anal exhaust after operation[(3.24±0.73) days vs. (3.50±0.95) days]beeween one-stage surgery group and control group, but hospital stay[(15.1±2.3) days vs. (23.1±4.1) days]and hospital expense[(3.70±0.68) ×105 yuan vs. (5.77±0.95) ×105 yuan]of one-stage surgery group were lower than those of control group (P<0.05). In addition, there were no significant difference in the incidences of wound infection[7.3% (3/41) vs. 10.0% (4/40)], intraabdominal infection[4.9% (2/41) vs. 10.0% (4/10)], pulmonary infection[12.2% (5/41) vs. 15.0% (6/40)], and anastomotic leakage[2.4% (1/41) vs. 5.0% (2/40)]beeween one-stage surgery group and control group (P>0.05). All of the cases were followed up for 1-36 months, and the median time were 22 months. There were no significant difference in the mortality[0 (0/41) vs. 2.5% (1/40)], recurrence rate[2.4% (1/41) vs. 5.0% (2/40)], and metastasis rate[7.3% (3/41) vs. 10.0% (4/40)]beeween one-stage surgery group and control group too (P>0.05). ConclusionIn the case of negative pressure drainage of double cavity casing, underwent decompression of the small bowel, and irrigation of colon, the primary resection and anastomosis of left colon cancer combined with acute obstruction was safe and feasible.
