Objective To determine the effect of interlocking intramedullary nail in treatment of open tibial and fibula fractures and analyze the method to promote the bone union. Methods From December 2003 to June 2006, thirtyfive patients with open tibial and fibula fracture were treated with emergency debridement, interlocked intramedullary fixation for tibia and fixed fibula at the same time. During operation, the bone marrow was collected and grafted into the fracture gaps. Among them, there were 27 males and 8 females, involving in 22 left legs and 13 right legs. Their ages ranged from 19 to 65 years, with an average of 34.7 years. The location of fracture was the middle of the tibia and fibula in 16 cases, the distal 1/3 of the tibia and fibula in 12 cases and the proximal 1/3 in 7 cases. According to the Gusitilo classification of open injuries, there were 7 cases of type I, 19 cases of type II, 8 cases of type III a and 1 case of type III b. The mean range of knee motion was 48.3° (45-70°). The mean time from injury to operation was 4.3 hours (50 minutes to 7 hours). Results The mean operation time was 94 minutes (60-132 minutes) and the mean blood loss was 122 mL (100-350 mL). The wound healed by first intention in 32 patients. Incision was sutured in 2 cases of type III a fractures after operation 4 days, gastrocnemius flap graft was performed in 1 case of type III b fracture 1 week after operation. They all achieve good heal ing. No fractures spl it off, no iatrogenic nerve and vascular injury occurred, no osteofascial compartment syndromes or deep vein thrombus happened. Tension bl isters appeared in 1 case of type II fracture after operation and subsided after 5 days. Patients were followed up for 14-43 months (mean 22 months). The X-ray films showed that fracture union was observe in 30 cases after 14 weeks of operation, in 3 cases after 18 weeks and in 1 caseafter 22 weeks of operation. The fractures union time was 15.2 weeks on average. About 2 cm nonunion in lateral tibial appeared in 1 case of type I fracture. No fracture occurred again. The mean range of knee motion was 127° (121-135°). The mean HSS score was 96.5 (87-100) at the end of the follow-up. The excellent and good rate was 100%. Conclusion The curative effect of interlocking intramedullary nail is definite in treatment of open tibial and fibula fractures and it can enhance fracture union to plant bone marrow into the fracture gaps.

Methods The distally based superficial sural artery flap was designed on the posterior aspect of the leg. From February 2000 to December 2003, 18 patients with skin and soft tissue detects of the lower leg, ankle and foot were treated with island fasciocutaneous flap supplied by superficial sural artery by emergency. The size of the flap ranged form 4 cm× 5 cm to 11 cm×12 cm. Results The flaps survived totally in 16 cases and necrosed partially in 2 cases. After 1-2 year postoperative follow-up, the results were satisfactory except that in 2 flaps. Conclusion The island fasciocutaneous flap supplied by superficial sural artery may provide a useful method for emergency repair of soft tissue defect of the lower limbs.
Objective To explore the utilization of emergency materials for mass disaster. Methods We retrospectively analyzed the 2 338 casualties from Wenchuan earthquake who visited our emergency department from 2:28 PM, May 12 to 2:28 PM, June 2. The injury condition and demand on emergency materials at different phase were also analyzed.Results mong the 2 338 casualties, the most common injuries were fracture, skin or soft tissue injury, and brain injury. Primary drugs are tetanus immune globulin, normal sodium and antibiotics. The injury condition and demand on medical resource were different at different phase. The demand on emergency materials depended on the category and severity of injury. Conclusion It is necessary to make a good medical resource planning for mass disaster. The catogory of injury and demand on emergency materials are different at different phase.
Objective To study traits and influencing factors of coping styles in the military groups of social emergency responders for special service and provide a theoretical basis for epidemiologic intervention. Methods A cross-sectional survey on coping styles and their influencing variables was carried out among 12 special service companies from Armed Police Forces and Fire Units of Public Security stationed in Chongqing by means of cluster sampling. Then, different coping styles were compared with general military personnel, the types and maturity degree of coping behaviors were evaluated, and major influencing variables were screened. Results Of 396 subjects, 86.36% had field experience in handling emergencies. The population’s average levels of coping styles are significantly higher than the military norm (P≤0.01), and the overall type of coping behaviors is mature. Although the relevance between the performance type and the number of 6 coping styles scores reaching the military masculine norm is significant (Plt;0.001), the Pearson contingency coefficient（c=0.23）represents a relatively limited maturity in coping styles. In view of direction and extent effects of various influencing factors, lack of survival skills, disaccord on self and experience, self-inferiority as well as self-stereotypes are negative factors. In addition to social support, self-flexibility responsibility may be positive factors. Use of social support, disaccord on self and experience, self-confidence and knowledge about danger-avoiding take universal impacts, and other factors take single impact on a certain coping style. Conclusion Coping styles in military groups of social emergency responders for special service are comparatively mature and stable, but there are significantly individual differences and a wide range of influencing factors. So, it is very necessary to advance maturity in coping styles through targeted interventions.
After Wenchuan earthquake, the West China Second University Hospital immediately started the preparation of emergency pharmaceutical administration. The pharmaceutical department effectively controlled the provision, purchasing, utilization and donation of medications through a double-track operation system. In this way, the medication supply was ensured for both the patients suffering from the disaster and routine patients, which guaranteed the rationality in medication and promoted the utilization of the donated drugs so that more than 80 000 drug cost was saved for the hospital.
ObjectiveTo investigate the efficacy of Quality Control Circles (QCC) in reducing the emergency application times of maintenance hemodialysis. MethodsIn December, 2012, the quality circle was formed by eight nurses and a physician, through brainstorming. The group finally selected "Reducing emergency maintenance dialysis times" as the theme. With the help of questionnaire, interview, and comparative study, we analyzed the emergency situation of maintenance hemodialysis patients, and regulate and implement related policies. ResultsBy QCC practices, the times of hemodialysis declined from 11.7 to 5.3 cases per month, which exceeded our expectations largely. As to the circle members, their problem-solving skills, responsibility, communication skills, self-confidence, motivation and QCC techniques were also improved. ConclusionQCC can not only reduce the times of maintenance dialysis, but also improve the team cohesion, harmony and quality management capabilities.
Objective To study the feasibility, indication, technique of emergency operation and the perioperative management on critical congenital heart disease in infants. Methods From May 1998 to May 2003, 67 emergency operations of critical congenital heart disease were performed in infants . The age was 14d-32 months (mean , 11.8±8.9 months), the weight was 2.6-14.8 kg( mean, 8.4±3.0 kg). The diagnosis included ventricular septal defect in 39, tetralogy of Fallot in 13, complete atrioventricular septal defect in 5, total anomalous pulmonary venous drainage in 4, atrial septal defect with pulmonary valve stenosis in 3, D-transposition of the great arteries in 2, and postoperative pulmonary valve vegetation in 1. Corrective operation in 64 and palliative operation in 3 were done. Results The preoperative managing time was 0-9 d(mean , 3.7±2.6 d), the lasting time of intubation was 1-14d( mean, 3.8±3.2 d), and ICU staying time was 2-18 d (mean, 5.7±2.8 d). The operative mortality was 7.5% (5/67), the postoperative complications in other infants include 14 low cardiac output syndrome, 14 atelectasis, 8 lung infection, 2 worsened pulmonary hypertension, 1 pneumothorax , and 1 phrenic nerve paralysis. Following up 2-60 months with 1 case late death, the cardiac function of the others were class Ⅰ-Ⅱ/Ⅵ, the operative result was satisfactory. Conclusions The emergency operation on critical congenital heart disease in infants is safe, and can save most of their lives, the good result can be obtained from surgical treatment. Accurate choice of indications, and perioperative good nutritional and cardiorespiratory function support are important.
Objective To describe and analyze both the direct impact of emergency service (ES) cost sharing and the indirect impact of drug cost sharing on emergency service utilization (ESU) in health insurance plans. Methods The author searched18 electronic databases which were in the evidence-based, public health, economic and social categories, respectively, 2 grey literature review resources and Google search engine, and the retrieval time was from June 21st, 2011 to September 19th, 2011. According to the inclusion criteria, data screening and extraction were conducted by two reviewers independently, and the differences were discussed by a third person or a review group. The theme analysis was adopted to systematically analyze both the direct and indirect impacts of cost sharing on ESU. Additionally, the side effects were analyzed too. Results Among total 22 studies included, 13 described the direct impact of ESU cost sharing, while the other 9 referred to the indirect impact of drug cost sharing. There were mainly 5 categories of health plans involved in. The results showed that, ESU could respond to the cost sharing: ESU decreased when the proportion of copayment increased, and vice versa. The increase of drug copayment impaired the use of essential drugs and finally increased ESU. However, a modest ES copayment decreased the irrational ESU rather than the rational ESU. Conclusion To the insured, the increase of ES cost sharing would not decrease the rational ESU and has no adverse events, while the increase of drug cost sharing would lead to some adverse events such as the increase of ESU. To the uninsured, the impact of cost sharing needs to be further disccussed. So this review suggests, the proper ES self-payment should be introduced into the health insurance plans according to local economic status, resident income, etc.; in addition, the drug self-payment ratio should be determined cautiously.
