To evaluate the development prevention and treatment of pneumonic injury after operation on aged patients with abdominal infection. We analyzed 77 aged patients (＞60 y) admitted from Jan. 1991 to Dec. 1992: 38 cases of which with abdominal infection (infection group), 39 cases without abdominal infection (non-infection group). All patients were given oxygen therapy and continuous SaO2 monitoring. Results: There were 28 patients with hypoxemia (SaO2＜95%) in infection group, with an occurrence rate of 73.7%. In non-infection group (12 patients), the rate of hyoxemia was 30.8%, which has significant difference between two groups (Ｐ＜0.001). All patients with hypoxemia were given oxygen therapy and 31 patients′ SaO2 was elevated. The efficient rate was 77.5%. Other 9 patients developed ARDS, the rate was 2.5% (9/40). In the infection group 8 patients developed ARDS with an occurrence rate of 21.1%. There was one patient with ARDS in the non-infection group, the rate was 2.6%. There was significant difference between two group (Ｐ＜0.05). Conclusions: The results suggest that hypoxemia is liable to occur in aged patients with abdominal infection after operation and these patients were liable to develop ARDS. Oxygen therapy and SaO2 monitoring is the important managements to these patients in prevention of pneumonic injury.

Objective To evaluate the effectiveness and the value of balloon kyphoplasty in treating aged osteoporosis thoracolumbar vertebrae burst fracture. Methods Between January 2003 and January 2008, 36 thoracolumbar vertebrae burst fracture patients were treated. There were 15 males and 21 females with an average age of 65.4 years (range, 59-72 years). Fourteen cases had no obvious history of trauma, 19 had a history of sl ight trauma, and 3 had a history of severe trauma. Forty vertebral bodies were involved, including 1 T7, 3 T9, 8 T10, 10 T12, 9 L1, 7 L2, and 2 L4. All patients displayed local pain and osteoporosis by bone density measurement with no neurological symptom of both lower limbs. Balloon kyphoplasty through unilateral (31 cases) or bilateral (5 cases) vertebral pedicles with polymethylmethacrylate was performed at the injection volume of (3.46 ± 0.86) mL per vertebral body. Before and after operation, the anterior height and posterior height of fractured vertebral body and the sagittal displacement were measured. Results Two cases had intraoperative cerebrospinal fluid leakage; 1 case had no remission of waist-back pain and pain was released after symptomatic treatment. All 36 patients were followed up 2.3 years on average (range, 1.5-4.0 years). No cement leakage was found with good diffusion of cement on X-ray film. The restoration of the height of vertebral bodies was satisfactory without nerve compression symptoms and other compl ications. The Visual Analogue Score at last follow-up (2.34 ± 1.03) was significantly lower than that of preoperation (6.78 ± 1.21), (P lt; 0.05). The compressive percentage of anterior height (19.80% ± 1.03%) of fractured vertebral body after operation was significantly lower than that before operation(25.30% ± 2.50%), (P lt; 0.05). There was no significant difference in posterior compressive percentage and sagittal displacement between pre- and post- operation (P gt; 0.05). Conclusion Based on roentgenographic scores, balloon kyphoplasty is selectively used to treat aged osteoporosis thoracolumbar vertebrae burst fracture, and the radiographic and cl inical results were satisfactory.
Objective To evaluate the effect of minimally invasive dynamic hip screws (MIDHS) in treating aged intertrochanteric fractures. Methods From April 2006 to March 2008, 49 aged patients with intertrochanteric fractures were treated with MIDHS. There were 22 males and 27 females, aged 65-78 years (average 70.2 years). Frature was caused by trafficaccident in 7 cases, by fall ing from height in 3 cases, and by injury from fall in 39 cases. The time from injury to operation was 2-12 days (average 5.5 days). According to Evans classification, there were 28 cases of types I, II (stable fracture) and 21 cases of types III, IV (unstable fracture). If the Singh index≤3 was defined as osteoporosis, the osteoporotic rate was 71.4% (35/49). All patients were on a radiolucent fracture traction table and their fractures had satisfactory closed reduction. After the guide wire was inserted and reamed under fluoroscopy, the lag screw and side plate were introduced through the small incision. In all unstable fractures, an additional, antirotational and large cancellous bone screw was used cranial to the DHS. Results The average operation time was 65.2 minutes. The average blood loss was 189.3 mL. All patients had satisfactory reduction and 79.6% (39/49) had adequate lag screw positions. The average postoperative hospital ization days was 5.8 days (3-12 days). All incision healed at stage I. There was no postoperative complications. Forty-nine patients were followed up 12 to 30 months (average 19.8 months). Fractures healed within 16 weeks in 47 patients and the average healing time was 13.1 weeks (12-16 weeks). The average Harris scoring was 90.8 (75-95). Implant failure and nonunion occurred in 2 cases, no serious compl ication occurred in other patients. Conclusion The MIDHS is a simple, safe and effective method for treatment of aged intertrochanteric fractures.
OBJECTIVE To summarize the clinical results of hollow compression screw in treatment of fracture of neck of femur in the aged. METHODS: From November 1993 to October, 1998, 52 aged patients with several types of fracture of neck of femur were treated; among them, there were 25 males and 27 females aged from 60 to 83 years (70 years on average). There were 48 cases of fresh fracture and 4 cases of old fracture. Forty-two cases were performed closed reduction internal fixation, 10 cases with open reduction internal fixation. RESULTS: All the patients could sit by themselves 4 to 6 days after operation, and could walk with a crutch 10 to 15 days after operation. The mobility of hip joint was nearly normal 4 weeks after operation. All the patients were followed 26 to 84 months, 48.5 months on average. Bone union was achieved in 50 cases, nonunion in 2 cases. The average healing time was 4.7 months. There were no other complications, such as ankylosis and muscular atrophy, but ischemic necrosis in 3 cases. CONCLUSION: This method has following advantages, convenient manipulation, less injury, stable fixation, and the short-term recovery, which avoid some common complications. It is a reliable method worthy of popularizing.
Objective To investigate the prevalence of high myopia，the prevalence and risk factors of high myopia associated with chorioretinopathy in residents aged 60 years or over in Beixinjing community, Shanghai, China.Methods A cluster stratified random sampling method was used to screen 4153 people aged 60 and over in Beixinjing community. There were 3851participants in total with a 9273% response rate. Participants were invited to complete a questionnaire and received a comprehensive eye examination including visual acuity, refraction, slitlamp microscopic examination, direct ophthalmoscopy and fundus photography and so on. Spherical equivalent (SE) was used to determine the degree of refractive errors. The diagnosis of high myopic chorioretinopathy was made if SEgt;-6.00 D and myopic chorioretinal atrophy lesions were presented such as posterior scleral staphyloma, lacquer cracks, Fuchs spot and myopic arc spots. The degree of visual acuity impairment was determined according to the World Health Organization (WHO) classification as low vision (the best corrected visual acuity ge; 0.05, but lt;0.3) or blindness (the best corrected visual acuity lt;0.05).Results There were 207/3851(5.37%) high myopia patients, in which 183/207 (88.40%) patients were associated with myopic chorioretinopathy. The prevalence of myopic chorioretinopathy decreased while age increased (chi;2=19.21, Plt;0.01), but statistically there was no gender difference （chi;2=1.83, Pgt;0.05）. Logistic regression analysis showed that there were significant differences in the prevalence of high myopia between people with different age, educational levels and family history （chi;2=19.21，32.08，960.68；Plt;0.01）.There were 29 cases of bilateral blindness, 96 cases of unilateral blindness,104 cases of bilateral low vision and 562 cases of unilateral low vision in those participants. In 183 cases of high myopic chorioretinopathy patients, 111（60.65 %）cases had an obvious visual impairment, including 3448% (10 cases) of bilateral blindness, 1146% (11 cases) of unilateral blindness, 2981% (31 cases)of bilateral low vision and 1050% (59 cases) of unilateral low vision.Conclusions The prevalence of high myopia of residents aged ge;60 years in Beixinjing community, Shanghai,China is relatively high. Age, education level and family history are the most important factors affecting the occurrence of chorioretinopathy in high myopia patients.
Objective To verifying the characteristics of optical coherence tomography(OCT) in exudative age-related macular degeneration (AMD). Methods The patients being investigated in this series included 16 cases (19 eyes) of exudative age-related macular degeneration diagnosed by FFA and OCT examinations, among them 4 cases (6 eyes) were examined with ICGA. The color photographs of ocular fundi, FFA, ICGA and OCT were investigated by contrasting each other. Results As compared with the FFA and ICGA examinations, the characteristic findings found in OCT in patients with exudative AMD in this series were as the following:①serous detachment of neurosensory epithelium in 11 eyes,②retinal hemorrhage in 2 eyes,③serous detachment of retinal pigment epithelium in 5 eyes,④hemorrhagic detachment of retinal pigment epithelium in 10 eyes,⑤disciform scar in 4 eyes,⑥fibrovascular pigment epithelial detachment and occult CNV in 12 eyes. Conclusion OCT can supply a comprehensive survey of exudative AMD, in making the diagnosis as an important complementary examination of FFA and ICGA. (Chin J Ocul Fundus Dis,2000,16:220-223)
Objective To study the ultrasonographic manifestation character of age-related macular degeneration (AMD). Methods The ultrasonographic manifestation of thirty-five cases (38 eyes) of AMD diagnosed by fundus fluorescein angiography (FFA) with positive findings of ultrasonic B-scan were analysed． Results The ultrasonic appearance of interlamellar transaudient cleft were found in 26 eyes, in which FFA appearance were serous detachment of pigment epithelium and subretinal neovascularization, 5 of them associated with small excavation of choroid, 4 of them associated with b echo belt at the posterior edge of the interlamellar transaudient cleft in which the FFA appearance was extensive subretinal neovascularization．In another 4 eyes with choroidal hematoma under FFA revealed thin echo light spots in the interlamellar transaudient cleft． There was scar-staining in the other 8 eyes in which the ultrasonic appearance showed an unequal thickening of the ocular wall in the posterior pole,unequal echo of interior edge and irregular inner echo． Conclusion The main ultrasonographic manifestation of AMD is the presence of interlamellar transaudient cleft in the thickened ocular wall.
