ObjectiveTo explore the application of 10% sodium chloride for stage-Ⅲ pressure ulcer debridement. MethodsAccording to the standard, 68 stage-Ⅲ pressure ulcer cases were selected from January 2011 to December 2014. All the patients had yellow surface and positive bacterium cultivation suggesting wound infection. They were randomly divided into control group and trial group. The control group used traditional treatment for debridement, while the trial group used 10% sodium chloride, until the end of debridement where the granulation became fresh and bacterium cultivation negative. Then we compared these two groups in terms of debridement time, wound drainage, wound smell, granulation growth, pain score and cost. ResultsThe control group debridement time was 18-32 days, averaging (22.4±10.8) days, and the trial group debridement time was 5-13 days, averaging (11.6±4.0) days (P<0.05). The control group wound drainage ratings score was 6.70±2.87, while the trial group wound drainage ratings score was 3.65±1.23 (P<0.05). In terms of the wound smell, the control group had a score of 2.74±1.62, and the score for the experimental group was 1.26±0.51 (P<0.05). The average cost of the control group was (975.00±10.29) yuan, while the experimental group was (626.00±8.18) yuan (P<0.05). ConclusionThe application of 10% sodium chloride for stage-Ⅲ pressure ulcer debridement can shorten debridement time, promote the growth of granulation and reduce the economic burden, which is worth clinical promotion.
ObjectiveTo evaluate the feasibility and effectiveness of one-stage posterior retaining part facet joint in laminectomy, bone graft and debridement combined with short segmental pedicle screw fixation for lumbosacral spinal tuberculosis. MethodsBetween January 2010 and December 2014, 32 cases of lumbosacral spinal tuberculosis (L4-S1) were treated by one-stage posterior retaining part facet joint in laminectomy, bone graft and debridement combined with short segmental pedicle screw fixation. There were 20 males and 12 females, aged 17-62 years (mean, 43 years). The disease duration was 12-48 months (mean, 18 months). The involved segments included L5, S1 level in 19 cases and L4, 5 level in 13 cases. The effectiveness was evaluated by Oswestry disability index (ODI) and imaging parameters (lumbar-sacral angle correction and Bridwell classification and CT fusion criteria) after operation. ResultsThe operation was successfully completed in all patients; the average operation time was 180 minutes, and the average intraoperative blood loss was 400 mL. All cases were followed up 12 to 67 months (mean, 15.6 months). At last follow-up, common toxic symptom of tuberculosis disappeared, and no internal fixation failure occurred. Neurological function was recovered to normal in 7 patients with neurological symptoms, and American Spinal Injury Association (ASIA) scale was improved to grade E from grade C (2 cases) and grade D (5 cases) before operation. At 1 year and last follow-up, the ODI scores were significantly improved when compared with preoperative score (P < 0.05), but no significant difference was found between at 1 year and last follow-up (P>0.05). The lumbarsacral angle was significantly increased at 7 days, 1 year and last follow-up when compared with preoperative one (P < 0.05), but there was no significant difference between different time points after operation (P>0.05). The bone graft fusion time was 9-24 months (mean, 12 months). At 1 year after operation and last follow-up, X-ray Bridwill bone fusion rates were 87.50% (28/32) and 93.75% (30/32) respectively, and CT fusion rates were 87.50% (28/32) and 90.63% (29/32) respectively; and there was significant difference in interbody fusion between at 1 year and last follow-up (P < 0.05). Drug resistance was observed in 4 cases; Bridwill gradeⅢand gradeⅣfusion was shown in 3 cases and 1 case after adjusting the anti-tuberculosis scheme after 1 year. ConclusionOne-stage posterior retaining part facet joint in laminectomy and debridement can effectively clear the tuberculose focus, intervertebral bone graft combined with short segment pedicle screw fixation can maintain postoperative spinal reliable stability and get satisfactory bone fusion rate, so it is an effective method for the treatment of lumbosacral tuberculosis.
Objective To investigate the cl inical outcomes of one stage debridement and closed-suction drainage for treatment of infection after lumbar instrumentation. Methods Between June 2002 and March 2008, 12 patients with infection after lumbar instrumentation were treated with one stage debridement and closed-suction drainage, including 9 males and 3females and aging 35-68 years (48.5 years on average). The disease duration varied from 7 days to 183 days (56 days on average). The segments of internal fixation included 7 cases single segment at levels of L4, 5, 4 cases of double segments at levels of L 4, 5, L5, S1 (2 cases), and L3, 4, L4, 5 (2 cases), and 1 case of three segments at levels of L3, 4, L4, 5, L5, S1. Two patients were treated with internal fixator removal. Results The bacterial culture results of intervertebral discs were positive in 8 cases for Staphylococcus aureus and in 3 cases for Enterobacter cloacae, negative in 1 case. Primary healing of incisions were achieved in all cases. Twelve patients were followed up 18-53 months (34.7 months on average). The white blood cell count, erythrocyte sedimentation rate, and C reactive protein significantly decreased after operation, showing significant differences at 15 days after operation when compared with those before operation (P lt; 0.05). No obvious low back pain was observed. Pathological-changed vertebra-space fused. No displacement and breakage of internal fixator occurred; in 2 patients who were given internal fixator removal, no removal of the instrumentation was performed again. The X-ray films showed that the average kyphosis decreased 0.8° at 18 months after operation. At last follow-up, the visual analogue scale score was 2 ± 1, showing significant difference (P lt; 0.05) when compared with that (10 ± 2) before operation. Conclusion One stage debridement and closed-suction drainage therapy is an effective method for treating infection after lumbar instrumentation. The operation is easy and can reduce hospitalization days.
ObjectiveTo investigate the effect of delayed sternal closure (DSC) on sternal wound debridement after pediatric cardiac surgery. MethodsWe retrospectively analyzed clinical data of 491 pediatric patients underwent DSC in Guangdong General Hospital between June 2009 and June 2014. There were 333 males and 158 females with age of 1 day to 153.37 (5.68±17.24) months. The rate of sternal wound debridement between the DSC patients and the non-DSC patients was compared. ResultsA total of 454 pediatric patients with DSC initiated in the operation room. And 37 patients with DSC initiated in intensive care unit after emergency sternotomy. A total of 392 patients with delayed sternal closure were discharged. Eight patients gave up treatment for family reasons and 91 patients died. Patients with DSC had higher incidence of sternal wound debridement than the patients with non-DSC did (χ2=6.693, P=0.010). ConclusionDSC is an effective treatment for children with severe cardiac surgery, while it causes higher incidence of sternal wound debridement.
Objective To overview the effect of bacterial biofilms (BBF) on the formation of chronic osteomyel itis and the treatment measure. Methods The original articles in recent years about the relationship between BBF and chronic osteomyel itis were reviewed. Results The diagnosis and treatment of chronic osteomyel itis was very difficult, besides hyperplasia oflocal scar, poor blood supply, drug-resistant, forming of BBF also was an important reason. BBF formed on the surface of necrosis soft tissue and dead bone. Due to the protection of BBF, the bacterium were far more resistant to antimicrobial agents, which caused the recurrence of chronic osteomyel itis. The forming of BBF included three processes which were adhesion, development and maturity. As the major pathogens of chronic osteomyel itis, staphylococcus had its own characteristic. Designing therapeutic programmes according to these characteristics had become the trend of anti-infection treatment of BBF. Conclusion Although there are lots of studies on anti-biofilm due to the key factors during the forming of BBF, the most effective way of anti-biofilm is still debridement.
Objective To investigate the effect of arthroscopy debridement and drainage on treating septic arthritis of the knee. Methods Twenty-one cases of acute knee septic arthritis were treated by debridement and synovectomy under arthroscopy and combined with intravenous antibiotics and systematic postoperative rehabilitation. Results The temperature resumed to normal after 3 days of operation. All the knees achieved the normal extension and more than 120 degree of flexion 8 weeks after operation. The clinical results were evaluated through examination of temperature and range of motion of the knee joint. All patients had excellent result. All the cases were followed for 1 to 3 years. No majorcomplications related to the arthroscopy of the knee resulted. According to theNoyes, the rate of excellence and the good was 95.2%. Conclusion Early diagnosis and treatment are mandatory for patients with septic arthritis of the knee. The success of arthroscopy treatment of septic arthritis with diminished morbidity makes arthroscopy an excellent alternative to open surgery.
Objective To investigate the method and effectiveness of vacuum seal ing drainage (VSD) combined with debridement for treatment of deep infection after hip or knee replacement. Methods Between September 2006 and May 2010, 13 cases of deep infection after joint replacement surgery were treated, including 5 males and 8 females with an average ageof 62.5 years (range, 56-78 years). Infection occurred at 7 days to 1 year and 2 months (median, 14 days) after joint replacement surgery. The time from infection to admission was 8 days to 4 years and 6 months (median, 21 days). Purulent secretion with or without blood were observed in all patients; sinus formed in 5 cases; and unhealing of incision or drainage opening disunion were observed in 8 cases. The size of skin defect at secretion drainage or sinus opening site was 5 mm × 3 mm to 36 mm × 6 mm; the depth of drainage tunnel or sinus was 21-60 mm. The histopathological examination in 11 patients showed acute infection or chronic infection with acute onset in 10 cases, and tuberculosis in 1 case. In 6 cases of secretion culture, Staphylococcus aureus was isolated from 5 cases. After thorough debridement, wound irrigation was performed during the day and VSD during the night in 10 cases. VSD was merely performed in 3 cases. Results In 1 case after revision total hip arthroplasty, the wound bled profusely with VSD, then VSD stopped and associated with compression bandage, VSD proceeded again 3 days later with no heavy bleeding. All the patient were followed up 1 year to 4 years and 5 months (mean, 2 years and 11 months). Infection were controlled 7-75 days (mean, 43 days) after VSD in 10 cases. In these cases, prosthesis were reserved, no recurrent infection was observed, wound were healed, limb function were reserved. VSD was refused in 1 case because of hypersensitive of the pain at the vacuum site, infection control was failed and amputation at the thigh was proceeded. The effect was not evident in 1 case with tuberculosis infection, then the prosthesis was removed and arthrodesis was proceeded followed by complete union. In 1 case, infection was cured with VSD, recurrent infection happened after 9 months, antibiotic-impregnated cement spacer was used at end, and no recurrence was observed 1 year and 4 months later. Conclusion VSD combined with debridement can drainage deep infection sufficiently, promote wound healing, reduce recurrent infection rate, maximize the possibil ity of prosthesis preservation.
ObjectiveTo compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment. MethodsA retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed. ResultsIncision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood lossof group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14-38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z=0.168, P=0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7±0.3) months in group A and (8.6±0.4) months in group B, showing no significant difference (t=0.591, P=0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found. ConclusionBased on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.
ObjectiveTo explore the effectiveness and safety of treatment of thoracic tuberculosis with thoracoscope supported by digital technology. MethodsBetween June 2010 and February 2012, 11 patients with thoracic tuberculosis were treated and the clinical data were retrospectively analyzed. There were 7 males and 4 females with an average age of 23.6 years (range, 16-47 years) and an average disease duration of 16 months (range, 6-18 months). Two vertebral bodies and one intervertebral space were involved at T6-11. At preoperation, the neurologic function degree was classified as Frankel grade E. Three dimensional reconstruction of thorax and spine and surgical procedure design (including focal clearance, bone grafting, and screw fixation) were done at SUPERIMAGE workstation. Surgery procedures were conducted following the preoperative designs. ResultsThe operative procedures were consistent with preoperative designs. All of these operations were successfully performed. The mean time of operation was 146 minutes (range, 120-180 minutes); the mean blood loss was 120 mL (range, 100-150 mL); the mean indwelling time of closed thoracic drainage was 38 hours (range, 24-48 hours); and the mean hospitalization time was 4.6 days (range, 3-5 days). Eleven patients were followed up 12-25 months (mean, 16 months). No complication of nerve damage, incision pain and infection, or pulmonary infection was observed. Rigid fixation and born fusion were obtained at last follow-up; no obvious change of thoracic vertebral alignment was detected and no internal fixation failure occurred. ConclusionIt is a minimally invasive, effective, and safe method to treat thoracic tuberculosis with thoracoscope supported by digital technology.
Objective To summarize the effect of one-stage anterior debridement of infection in function reconstruction of anterior and middle column for the treatment of thoracolumbar spinal tuberculosis. Methods From January 2001 to January 2007, 65 patients with thoracolumbar spinal tuberculosis were treated with one-stage anterior debridement, decompression, autogenous bone grafts and internal fixation. There were 43 males and 22 females with an average age of 40.2 years (range, 19-64 years), including 18 cases of thoracic tuberculosis (T4-10), 44 cases of thoracolumbar tuberculosis (T11-L2) and 3 cases of lumbar tuberculosis (L3-5). The disease course was 3 months to 10 years (median 10 months). One segment was involved in 7 cases, two segments in 54 cases and three segments in 4 cases. In 14 cases with spinalcord injury, there were 5 cases of grade C and 9 cases of grade D according to Frankel classification. The kyphotic Cobb angle was 20-65° (41° on average). Results The operative time was 120-210 minutes (170 minutes on average), and the blood loss was 300-1 500 mL (600 mL on average). Fifty-eight patients were followed up for 1-6 years (23 months on average). Abscess occurred in 2 cases at 40 days and 3 months, and healed after symptomatic management. The other incisions achieved heal ing by first intention. The X-ray films showed bony fusion 4-12 months (6 months on average) after operation. No tuberculosis recurred. At 12 months after operation, pain disappeared, and there were 7 cases of grade D and 7 cases of grade E according to Frankel classification. The kyphotic Cobb angle was 0-33° (24° on average), showing statistically significant difference (P lt; 0.05) when compared with preoperation. Conclusion Early reconstruction of load-bearing function and stabil ity of anterior and middle column in the treatment of spinal tuberculosis is great significant. The appl ication of one-stage anterior surgery with debridement, decompression, autogenous bone grafts and internal fixation in the operative treatment of thoracolumbar tuberculosis is safe and effective after a rigorous anti-tuberculosis treatment.
