Objective Based on the acquirable and optimized evidences at present, to explore the challenge and countermeasures for the development of nursing discipline in China, and to provide suggestions for promoting the construction of nursing discipline, platform, and talent team. Methods The study materials were searched in the following electronic databases including PubMed, EMbase, Web of Science, CNKI, VIP and CBM, as well as in the official websites of World Health Organization (WHO), International Council of Nurses (ICN), World Bank, the Ministry of Health (MOH) and the Ministry of Education (MOE) of China, and the domestic universities, colleges or technical secondary schools. Then the statistical analysis was conducted using SPSS 13.0 and Microsoft Excel software. Results a) By 2012, there were 855 nursing schools, 38 212 nursing undergraduates enrolled in universities, and 130 837 nursing students enrolled in junior colleges and senior vocational schools; b) The doctor-to-nurse ratio was 1 to 0.9 in 2010. The actual demand for doctors was 2.6 million, and there were still lack of 346 000 nurses; c) The age of nurses younger than 35 years old accounted for 50%. Those with primary professional title accounted for 64% to 69%, while less than 2.5% with advanced professional title; d) The training cost for a doctor and nurse/midwife in China only accounted for 2/5 of that in India and 1/5 to 1/4 in the sub-Sahara Africa; and e) To date, only 30.1% of disaster nursing studies in China provided research data, 30.6% were clinical experience and 38.3% were review. Conclusion Education and health systems need to be extensively reformed. It is necessary to train nursing students with core competencies using transformative learning. It is necessary to update textbooks and teaching methods, and funding should be appropriately increased. Nursing should cooperate with other disciplines, and apply evidence-based nursing methods to improve the quality of healthcare services and patient satisfaction.
Abstract: Objective To explore the protection of pulmonary function by shortening the thoracic opening time inesophagectomy of esophageal carcinoma. Methods A retrospective review of the postoperative pulmonary function of 54 patients with upper esophageal cancer undergoing esophagectomy with triple incisions in Tongji Hospital from January 2007 to April 2010 was conducted. The patients were divided into two groups. Twentyeight patients including 25 males and 3 females aged at 58.9±8.2 years were in in the classic procedure group, accepting classical esophagectomy with triple incision approach. Among them, there were 26 patients with squamous carcinoma and 2 with adenocarcinoma. Twentysix patients including 22 males and 4 females aged at 54.7±9.4 years were in the improved procedure group, accepting improved esophagectomy with triple incision approach. Among them, 25 patients had squamous carcinoma and 1 had adenocarcinoma. We analyzed the difference of the thoracic opening time, onelung ventilation time during the operation, arterial oxygen pressure (PaO2), arterial carbon dioxide differential pressure(PaCO2), pulse oximeter saturation (SpO2), postoperative mechanical ventilation time, intensive care unit (ICU) stay time, postoperative oxygen support days, postoperative inhospital days, and the incidence of pulmonary infection and respiratory failure between the two groups. Results There was a statistical difference between the two groups in thoracic opening time (4.7±1.2 hours versus 2.6±0.8 hours, t=7.51, Plt;0.05) and onelung ventilation time (3.7±15 hours versus 23±0.8 hours, t=4.23, Plt;0.05). The PaO2 and SpO2 on the 1st day and the 3rd day after operation were significantly lower than those before operation in both the classic procedure group (on the 1st day after [CM(159mm]operation, PaO2: F=516.03, Plt;0.05; SpO2: F=129.63, Plt;0.05; on the 3rdday after operation, PaO2: F=213.99, Plt;005; SpO2: F=61.84, Plt;0.05) and the improved procedure group (on the 1st day after operation, PaO2: F=423.56, Plt;0.05; SpO2: F=184.24, Plt;0.05; on the 3st day after operation, PaO2: F=136.78, Plt;0.05). On the 1st day after operation, PaO2 and SpO2 in the improved procedure group were significantly higher than those in the classic procedure group (F=36.20, Plt;0.05; F=93.42, Plt;0.05), while PaCO2 in the improved procedure group was significantly lower than that in the classic procedure group (F=155.49, Plt;0.05). On the 3rd day after operation, PaO2 in the improved procedure group was significantly higher than that in the classic procedure group (F=29.23, Plt;0.05). The postoperative mechanical ventilation time and ICU stay time in the improved procedure group were significantly shorter than those in the classic procedure group (t=3.81, P=0.00; t=4.65, Plt;0.05). Conclusion Improved esophagectomy of carcinoma with triple incision approach can significantly shorten the thoracic opening time and onelung ventilation time during operation, which plays a good role in protecting pulmonary function and lowering the incidence of pulmonary complications.
Objective To compare perioperative results between transventricular and transatrialtransventricular approaches in repairing tetralogy of Fallot (TOF), and to improve the surgical results. Methods The data of 1 423 consecutive patients who underwent complete repair of TOF between January 1998 and December 2007 were reviewed. 736 patients were repaired by the transventricular approach,and 687 patients by the transatrialtransventricular approach. Results Patients repaired by transventricular approach decreased from 100% in 1998 to 65% in 2002, and by transatrialtransventricular approach increased from 35% in 2002 to 79% in 2007. Aortic clamping time, cardiopulmonary bypass (CPB) time,mechanical ventilation time,and intensive care unit (ICU) stay in patients repaired by transatrialtransventricular approach had less than those in patients repaired by transventricular approach. No difference in transvalve patch ratio.There was lower morbidity in patients repaired by transatrialtransventricular approach in one to two organ systems dysfunction than that in patients repaired by transventricular approach. No difference in three or more organ systems dysfunction between them. Rate of residual ventricular septal defect(VSD), right ventricule to mean pulmonary artery (MPA) pressure gradient, tricuspid regurgitation, pulmonary artery regurgitation and arrhythmia in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Reoperative rate and mortality in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Conclusion TOF repair by the transatrialtransventricular approach fits to the actual conditions in China.
Objective To evaluate the surgical approach of left superior vena cava（LSVC） distal abnormalities in infant and young children. Methods From April 1999 to December 2004, 19 cases of LSVC distal abnormalities were corrected by primary repair. There were 10 males and 9 females. Their age ranged from 2.7 months to 6.5 years and body weight from 3. 1 to 15.0 kg. Diseases complicated with LSVC included complex congenital cardiac disease 9 cases, ostium secundum atrial septal defect 4, partial abnormal pulmonary venous drainage （PAPVD） with atrial septal defect（ASI）） 2, tetralogy of Fallot（TOF） 3, and double outlet of right ventricle （DORV） 1 case. The ways for surgical treatment of distal abnormalities of LSVC were reconstruction of atrial septum, translocation of LSVC and reconstruction of atrial septum, right atrium and LSVC anastomosis, cavopulmonary anastomosis and repair of partially unroofed coronary sinus. Results One patient died and the diagnosis for the patient was LSVC with DORV and pulmonary hypertension （PH）. This patient died from crisis of PH , obstruction of blood flow in the left cavopulmonary anastomosis, severe low cardiac output,low arterial oxygen saturation and abnormal function of kidney. The mean pressure of right atrium was 9 to 18 mmHg. The percutaneous oxygen saturation （SpO2） was 0.98 1.00 for biventricular repair and 0.79-0. 88 for single ventricular repair and palliative repair. The echocardiography showed no obstruction of the blood flow in LSVC and pulmonary veins. The results of follow-up were satisfactory, from 3 months to 2 years. Conclusions Key for success of surgical approach of LSVC distal abnormalities is precise evaluation of different kinds of LSVC and different surgical approaches. Cavopulmonary anastomosis can not be used in the case of LSVC with PH.
Objective To assess the effectiveness of the new anterolateral approach of the distal femur for the treatment of distal femoral fractures. Methods Between July 2007 and December 2009, 58 patients with distal femoral fractures were treated by new anterolateral approach of the distal femur in 28 patients (new approach group) and by conventional approach in 30 patients (conventional approach group). There was no significant difference in gender, age, cause of injury, affected side, type of fracture, disease duration, complication, or preoperative intervention (P gt; 0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, hospitalization days, and Hospital for Special Surgery (HSS) score of knee were recorded. Results Operation was successfully completed in all patients of 2 groups, and healing of incision by first intention was obtained; no vascular and nerves injuries occurred. The operation time and intraoperative fluoroscopy frequency of new approach group were significantly less than those of conventional approach group (P lt; 0.05). But the intraoperative blood loss and the hospitalization days showed no significant difference between 2 groups (P gt; 0.05). All patients were followed up 12-36 months (mean, 19.8 months). Bone union was shown on X-ray films; the fracture healing time was (12.62 ± 2.34) weeks in the new approach group and was (13.78 ± 1.94) weeks in the conventional approach group, showing no significant difference (t=2.78, P=0.10). The knee HSS score at last follow-up was 94.4 ± 4.2 in the new approach group, and was 89.2 ± 6.0 in the conventional approach group, showing significant difference between 2 groups (t=3.85, P=0.00). Conclusion New anterolateral approach of the distal femur for distal femoral fractures has the advantages of exposure plenitude, minimal tissue trauma, and early function rehabilitation training so as to enhance the function recovery of knee joint.
Objective To observe the effectiveness of the superior fibular head approach for the treatment of posterolateral fracture of the tibial plateau. Methods Between June 2010 and February 2012, 20 cases of posterolateral fracture of the tibial plateau were treated through superior fibular head approach, including 1 case of simple posterolateral fracture of the tibial plateau and 19 cases of posterolateral fracture of the tibial plateau with other fractures. There were 12 males and 8 females with an average age of 42.2 years (range, 28-58 years). All patients had closed fractures. Fracture was caused by traffic accident in 14 cases, by falling from height in 4 cases, and by twist injury in 2 cases. Associated injuries included lateral meniscus injury in 5 cases, medial meniscus injury in 2 cases, and anterior cruciate ligament injury in 1 case. The time from injury to admission ranged from 90 minutes to 32 hours (mean, 4.5 hours), and the time from admission to operation was 5-12 days (mean, 7.8 days). All cases underwent fracture reduction and fixation with Pilon plates through the superior fibular head approach, and associated fracture and meniscal injury were treated. Results All incisions healed by first intention, and no numbness or articular instability occurred. All patients were followed up 6-26 months (mean, 19.1 months). The average fracture healing time was 10.2 weeks (range, 8-12 weeks). During following-up, no related complication of fixation loosening or articular surface loss occurred. According to Rasmussen knee score criteria at last follow-up, the score was 18-30 (mean, 27.9); 16 cases were graded as excellent, 3 cases as good, and 1 case as fair, with an excellent and good rate of 95%. Conclusion The superior fibular head approach for the treatment of posterolateral fracture of the tibial plateau is simple, safe, and effective, and can achieve a good surgical outcome.
Objective To study the effectiveness of anterolateral C-shaped approach in the treatment of intertrochanteric fracture of the femur in elderly patient by comparing with traditional anterolateral approach. Methods Between April 2010 and November 2011, 66 patients with intertrochanteric fracture of the femur were analyzed retrospectively. Of 66 patients, 37 underwent improved anterolateral C-shaped approach combined with fixation of dynamic hip screw (DHS) (improved group), and 29 underwent traditional anterolateral approach combined with fixation of DHS (conventional group). There was no significant difference in gender, age, injury cause, side, disease duration, fracture type, and complication between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, postoperative drainage volume, and hospitalization time were recorded; and X-ray films were taken to observe the fracture healing. The hip function was evaluated according to self-established criterion. Results The operation was successfully completed in all patients, and primary healing of incision was achieved. All patients were followed up 12-24 months (mean, 17.8 months). Bone union was achieved in both groups; the fracture healing time was 3-6 months (mean, 4.8 months). No loosening or breaking of internal fixation was observed during follow-up period. The operation time and postoperative drainage volume of improved group were significantly less than those of conventional group (P lt; 0.05); no significant difference was found in intraoperative blood loss and hospitalization days between 2 groups (P gt; 0.05). According to self-established criterion, improved group was significantly better than conventional group in recovery of hip joint motion and function at 6 and 12 months after operation (P lt; 0.05). Conclusion Anterolateral C-shaped approach combined with DHS could minimize muscle injury and scar formation, which is beneficial to surgical exposure and early postoperative rehabilitation.
Objective To discuss the effectiveness of anterolateral decompression and three column reconstruction through posterior approach for the treatment of unstable thoracolumbar fracture. Methods Between March 2009 and October 2011, 39 patients with unstable burst thoracolumbar fracture were treated. Of them, there were 32 males and 7 females, with an average age of 43.8 years (range, 25-68 years). The injury causes included falling from height in 17 cases, bruise in 10 cases, traffic accident in 4 cases, and other in 8 cases. The fracture was located at the T10 level in 1 case, T11 in 9 cases, T12 in 6 cases, L1 in 14 cases, L2 in 7 cases, L3 in 1 case, and L4 in 1 case. According to Frankel classification before operation, 5 cases were classified as grade A, 5 as grade B, 9 as grade C, 14 as grade D, and 6 as grade E. Before operation, the vertebral kyphosis Cobb angle was (26.7 ± 7.1)°; vertebral height loss was 37.5% ± 9.5%; and the space occupying of vertebral canal was 73.7% ± 11.3%. The time between injury and operation was 1-4 days (mean, 2.5 days). All patients underwent anterolateral decompression of spinal canal by posterior approach and three column reconstruction. After operation, the vertebral height restoration, correction of kyphosis, decompression of the spinal canal, and the recovery of nerve function were evaluated. Results Increase of paraplegic level, urinary infection, and pressure sore occurred in 1 case, 1 case, and 2 cases, respectively; no incision infection or neurological complications was observed in the other cases, primary healing of incision was obtained. The patients were followed up 12-36 months (mean, 27 months). The patients had no aggravation of pain of low back after operation; no loosening and breaking of screws and rods occurred; no titanium alloys electrolysis and titanium cage subsidence or breakage was observed. The imaging examination showed that complete decompression of the spinal canal, satisfactory restoration of the vertebral height, and good physiological curvature of spine at 2 years after operation. At last follow-up, 1 case was classified as Frankel grade A, 2 as grade B, 2 as grade C, 10 as grade D, and 24 as grade E, which was significantly improved when compared with preoperative one (Plt; 0.05). At immediate after operation and last follow-up, the Cobb angle was (6.3 ± 2.1)° and (6.5 ± 2.4)° respectively; the vertebral height loss was 7.9% ± 2.7% and 8.2% ± 3.0% respectively; and the indexes were significantly improved when compared with preoperative ones (P lt; 0.05). Conclusion The technique of anterolateral decompression and three column reconstruction through posterior approach is one perfect approach to treat unstable thoracolumbar fracture because of complete spinal cord canal decompression, three column reconstruction, and immediate recovery of the spinal stability after operation.
【Abstract】 Objective To study the effectiveness of computer assisted pedicle screw insertion in osteoporotic spinalposterior fixation. Methods Between December 2009 and March 2011, 51 patients underwent pedicle screw fixation using the computer assisted navigation (navigation group), while 41 patients underwent the conventional technique (traditional group). All patients had osteoporosis under the dual-energy X-rays absorptiometry. There was no significant difference in age, gender, bone mineral density, involved segment, preoperative complications, and other general status between 2 groups (P gt; 0.05). The amount of blood loss, the operation time, the rate of the pedicle screw re-insertion, and the postoperative complication were observed. The state of the pedicle screw location was assessed by CT postoperatively with the Richter’s classification and the fusion state of the bone graft was observed using three-dimensional (3-D) CT scans during follow-up. Results A total of 250 screws were inserted in navigation group, and 239 were inserted successfully at first time while the other 11 screws (4.4%) were re-inserted. A total of 213 screws were inserted in traditional group, and 190 were successful at first time while 23 screws (10.8%) were re-inserted. There was significant difference in the rate of screws re-insertion between 2 groups (χ2=6.919, P=0.009). Both the amount of blood loss and the operation time in navigation group were significantly less than those in traditional group (P lt; 0.05). According to Richter’s classification for screw location, the results were excellent in 240 screws, good in 10 screws innavigation group; the results were excellent in 191 screws, good in 21 screws, and poor in 1 screw in traditional group. Significant difference was noticed in the screw position between 2 groups (χ2=7.566, P=0.023). The patients were followed up (7.8 ± 1.5) months in navigation group and (8.7 ± 1.5) months in traditional group. No loosening, extraction, and breakage of the pedicle screw occurred in navigation group, and all these patients had successful fusion within 6 months postoperatively. While in traditional group, successful fusion was shown in the other patients by 3-D CT, except the absorption of bone graft was found in only 1 patient at 6 months after operation. And then, after braking by adequate brace and enhancing the anti-osteoporotic therapy, the bone graft fused at 9 months postoperatively. Conclusion The computer assisted navigating pedicle screw insertion could effective reduce the deviation or re-insertion of the screws, insuring the maximum stabil ity of each screw, mean while it can reduce the exposure time and blood loss, avoiding complication. The computer assisted navigation would be a useful technique which made the pedicle screw fixation more safe and stable in patients with osteoporosis.
ObjectiveTo evaluate the effectiveness of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fractures with or without intravertebral clefts by unilateral approach and the impact of intravertebral clefts on the effectiveness. MethodsThe clinical data of 65 patients who met the inclusion criteria of osteoporotic vertebral compression fracture were retrospectively analyzed. According to having intravertebral clefts or not, the patients were divided into 2 groups: cleft group (group A, n=25) and non-cleft group (group B, n=40). There was no significant difference in gender, age, cause of injury, the level of fracture vertebrae, degree of damage, and interval of injury and operation between 2 groups (P gt; 0.05). All patients were given PVP procedure by unilateral approach. The operation time, the injected volume of bone cement, time to ambulate, complications, and adjacent vertebral re-fracture were recorded. The height of anterior and middle column and the posterior convex Cobb angle of injured spine were measured on the lateral X-ray film in standing position at preoperation and 1, 48 weeks after operation. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1, 4, and 48 weeks after operation. ResultsThere was no significant difference in the operation time and time to ambulate between 2 groups (P gt; 0.05). The injected volume of bone cement in group B was significantly less than that in group A (t=1.833, P=0.034). Asymptomatic cement leakage occurred in 6 patients (4 in group A and 2 in group B), in group A including 1 case of venous leakage, 2 cases of paravertebral leakage, and 1 case of intradiscal leakage; in group B including 2 cases of venous leakage. No symptomatic pulmonary embolism was observed. The vital sign was stable during operation and postoperatively. All patients were followed up 12-30 months (mean, 18.5 months). No re-fracture of the vertebrae occurred during the follow-up. The postoperative VAS score, ODI, the height of anterior and middle column, and the posterior convex Cobb angle of injured spine were improved significantly when compared with the preoperative ones in 2 groups (P lt; 0.05), but no significant difference was found between 2 groups at pre- and post-operation (P gt; 0.05). ConclusionPVP by unilateral approach is safty and efficacy in the treatment of osteoporosis vertebral compression fracture combined with intravertebral clefts. Intravertebral clefts have no significant impact on the effectiveness in the pain relief and function improvement.
