Analysis of causes and treatment methods of complication of early acute kidney injury in four severely burned patients / 中华烧伤杂志

Objective@#To analyze the causes of complication of early acute kidney injury (AKI) in four severely burned patients, and to explore the related treatment methods.@*Methods@#The clinical data of 4 patients with severe burn complicated with early AKI admitted to Guangzhou Red Cross Hospital Affiliated to Medical College of Jinan University (hereinafter referred to as our hospital) from June 2014 to December 2017 were retrospectively analyzed. All the patients were male, aged 23-33 (30±5) years old, with depth of burns ranged from deep partial-thickness to full-thickness, complicated with myofascial compartment syndrome of extremities and varying degrees of striated muscle injury, and treated in other hospitals before transfer to our hospital. The patients were numbered from small to large according to the total burn area. The total burn area of patients No. 1, 2, 3, and 4 was 10%, 80%, 90%, and 95% total body surface area respectively, their occurrence time of early AKI was 48, 11, 29, and 48 hours after injury respectively, and their time of arriving our hospital was 60, 11, 29, and 144 hours after injury respectively. Hypovolemic shock occurred in patients No. 2 and 3 at admission to our hospital. All the patients received continuous renal replacement therapy (CRRT) after admission to our hospital. Under the support of hemodynamic monitoring and organ function monitoring, the limbs complicated with myofascial compartment syndrome were incised, thorough decompression exploration was performed, and necrotic muscle tissue was removed or amputation was performed. After escharectomy and decompression of limbs, fresh granulation wounds were formed by temporarily covering wounds with Jieya dressing skin or pig skin, multiple debridements, and vacuum sealing drainage. Fresh granulation wounds and other wounds underwent staged eschar excision and shaving were covered with autologous Meek skin graft, particulate skin graft, reticular skin graft and small skin graft respectively. The treatment outcome, CRRT time, operation times, time of recovery of serum creatinine and myoglobin, length of hospital stay, and follow-up were recorded.@*Results@#All the 4 patients were cured after transfer to our hospital. Among them, totally 5 limbs of patients No. 1 and No. 4 underwent amputation because of complication of myofascial compartment syndrome and a large amount of necrotic muscle which could not be preserved. Patients No. 1, 2, 3, and 4 were treated with CRRT for 19, 35, 14, and 25 days respectively and performed with operation for 5, 6, 10, 8 times respectively. Serum creatinine of patients No. 1, 2, 3, and 4 returned to normal on 22, 35, 37, and 48 days after transfer respectively, and their serum myoglobin returned to normal on 18, 28, 25, and 30 days after transfer respectively. Patients No. 1, 2, 3, and 4 were hospitalized for 52, 105, 148, and 156 days and discharged after basic wound healing. Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients.@*Conclusions@#The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring.

Drug resistance and status of infection of Acinetobacter baumannii in burn intensive care unit during 3 years / 中华烧伤杂志

<p><b>OBJECTIVE</b>To analyze the detection, drug resistance, and status of infection of Acinetobacter baumannii (AB) in burn ICU during 3 years.</p><p><b>METHODS</b>A total of 2 010 specimens of wound secretion, blood, venous catheter attachment, sputum, stool and urine were collected from 505 burn patients hospitalized in our burn ICU from January 2011 to December 2013, and bacterial culture was performed. Pathogens were identified by automatic microorganism identifying and drug sensitivity analyzer. Drug resistance of all the obtained AB to 16 antibiotics commonly used in clinic, including cefoperazone/sulbactam, polymyxin, etc., was tested with K-B paper disk diffusion method. Patients with AB infection were ascertained. The WHONET 5.6 software was used to analyze the distribution of pathogens during 3 years, the isolation of AB with different sources and the status of drug resistance of AB to 16 antibiotics each year, and the status of patients with AB infection, and their outcome.</p><p><b>RESULTS</b>A total of 961 strains of pathogens were isolated, among which 185 (19.25%) strains were Gram positive cocci, 728 (75.75%) strains were Gram negative bacilli, and 48 (4.99%) strains were fungi. A total of 172 strains of AB were isolated, ranking the second place among all the detected pathogens, with 67 (38.95%) strains from wound secretion, 11 (6.40%) strains from blood, 23 (13.37%) strains from venous catheter attachment, and 71 (41.28%) strains from sputum, no AB strain was isolated from feces or urine. The AB strains were found sensitive to polymyxin and with relatively low drug resistance rate to minocycline, while the drug resistance rates were over 80.0% to the other 14 antibiotics commonly used in clinic in 2013. AB culture of wound secretion was positive in 27 patients. Among them, 7 patients suffered from wound infection, and the wound infection was caused by AB in 1 out of the 7 patients. AB culture of blood was positive in 7 patients. Among them, 3 patients suffered from bloodstream infection, and the infection was due to AB invasion in 1 out of the 3 patients. AB culture of venous catheter attachment was positive in 20 patients. Among them, 8 patients suffered from bloodstream infection, and the infection was due to AB invasion in 1 out of the 8 patients. AB culture of sputum was positive in 35 patients. Among them, 13 patients suffered from ventilatory associated pneumonia, and 2 out of the 13 patients were diagnosed as AB infection. A total of 69 patients were AB culture positive, among them 64 patients were cured, 2 patients were transferred to other hospitals, and 3 patients died, with the mortality rate of 4.35%.</p><p><b>CONCLUSIONS</b>AB in our burn ICU has a high detection rate and extensive drug resistance in above-mentioned 3 years. However, AB was mainly colonized in patients with extensive burns with a low mortality rate.</p>

Effects of unified surgical scheme for wounds on the treatment outcome of patients with extensive deep burn / 中华烧伤杂志

<p><b>OBJECTIVE</b>To investigate the effects of unified surgical scheme for wounds on the outcome of patients with extensive deep partial-thickness to full-thickness (briefly referred to as deep) burn.</p><p><b>METHODS</b>One hundred and thirty-seven patients with extensive deep burn hospitalized from July 2007 to November 2012 underwent unified surgery according to area of deep wound (unified scheme group, US). Among them, 57 patients with deep wound area less than 51% TBSA received escharectomy or tangential excision by stages followed by autologous mesh skin grafting; 52 patients with deep wound area from 51% to 80% TBSA underwent escharectomy or tangential excision by stages followed by autologous mesh skin grafting and/or small skin grafting, or escharectomy or tangential excision followed by large sheet of allogeneic skin covering plus autologous mesh skin grafting and/or small skin grafting after the removal of allogeneic skin; 28 patients with deep wound area larger than 80% TBSA received escharectomy or tangential excision by stages followed by autologous microskin grafting plus coverage of large sheet of allogeneic skin, or escharectomy or tangential excision followed by small autologous skin grafting and/or intermingled grafting with small autologous and/or allogeneic skin. Another 120 patients with extensive deep burn hospitalized from January 2002 to June 2007 who did not receive unified surgical scheme were included as control group (C). Except for the surgical methods in group US, in 53 patients with deep wound area less than 51% TBSA in group C escharectomy or tangential excision was performed followed by autologous small skin grafting; in 40 patients with deep wound area from 51% to 80% TBSA in group C escharectomy or tangential excision was performed followed by autologous microskin grafting plus large sheet of allogeneic skin covering, or escharectomy or tangential excision followed by large sheet of allogeneic skin embedded with stamp-like autologous skin; in 27 patients with deep wound area larger than 80% TBSA in group C escharectomy or tangential excision was performed followed by covering with large sheet of allogeneic skin embedded with stamp-like autologous skin without intermingled grafting with small autologous and allogeneic skin in group US. In group US, escharectomy of full-thickness wound in extremities was performed with the use of tourniquet in every patient; saline containing adrenaline was subcutaneously injected when performing escharectomy or tangential excision over the trunk and skin excision; normal skin and healed superficial-thickness wound were used as donor sites for several times of skin excision. The baseline condition of patients and their treatment in the aspects of fluid resuscitation, nutrition support, anti-inflammation, and organ function support were similar between the two groups. The mortality and incidence of complications of all patients and wound healing time and times of surgery of healed patients were compared between the two groups. Data were processed with independent sample t test, Mann-Whitney U test, and Fisher's exact test.</p><p><b>RESULTS</b>(1) Both the mortality and the incidence of complications of patients with deep wound area less than 51% TBSA in group US were 0, which were close to those of group C (with P values above 0.05). The number of times of surgery of healed patients with deep wound area less than 51% TBSA in group US was 2.4 ± 0.9, which was obviously fewer than that of group C (3.5 ± 1.8, U=-5.085, P<0.001), but with wound healing time close to that of group C (U=-1.480, P>0.05). (2) Both the mortality and the incidence of complications of patients with deep wound area from 51% to 80% TBSA in group US were 0, which were significantly lower than those of group C [both as 20.0% (8/40), with P values below 0.01]. The number of times of surgery and wound healing time of healed patients with deep wound area from 51% to 80% TBSA in group US were respectively 3.0 ± 1.0 and (43 ± 13) d, which were obviously fewer or shorter than those in group C [4.2 ± 2.3 and (61 ± 34) d, with U values respectively -2.491 and -2.186, P values below 0.05]. (3) Both the mortality and the incidence of complications of patients with deep wound area larger than 80% TBSA in group US were 25.0% (7/28), which were close to those of group C [both as 25.9% (7/27), with P values above 0.05]. The number of times of surgery and wound healing time of healed patients with deep wound area larger than 80% TBSA in group US were close to those of group C (with U values respectively -0.276 and -0.369, P values above 0.05).</p><p><b>CONCLUSIONS</b>Unified surgical scheme can indirectly decrease the mortality and the incidence of complications of burn patients with deep wound area from 51% to 80% TBSA; it can reduce times of surgery of healed patients of this type and shorten their wound healing time.</p>

Clinical efficacy of multimodal analgesic pain control on the posterior lumbar spine surgery / 中国综合临床

Objective To evaluate the efficiency of multimodal analgesia for the patients who had the posterior lumbar spine surgery.Methods Sixty-four cases of patients who were scheduled to the posterior lumbar spine surgery were randomly divided into two groups, multimodal analgesia group (n =32) and control group(n=32).Multimodal analgesia group patients were given oxycodone acetaminophen 1 day before and the next day after operation, during the operation the patients received injiection of multimodal drugs (consisting of ropivacaine 150 mg, flurbiprofen 50 mg, phenylephrine 0.4 ml, normal saline 50 ml) around the incisions by infiltrated injection before the skin incision closed, then had controlled intravenous analgesia.In the control group, the incisions were sutured without the local infiltration analgesia.Then only had patient controlled intravenous analgesia after operati on.Visual analogue scale(VAS) ,Japanese Orthopedic Association(JOA) and Prolo lumbar function score was recorded respectively perioperatively.Results (1) VAS: the patients of multimodal analgesia group had significantly lower rest pain scores and activity pain scores at 6, 12,24 hours, first moving than the control group((3.1±1.6) ,(2.8±1.1),(2.4±0.9) ,(2.3±1.1) vs.(3.5±1.8) ,(3.4± 1.3), (3.4±0.8), (3.0± 1.5), P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(2)JOA:JOA scores of the patients of multimodal analgesia group were obviously higher than that of the control group at 1,3,7 days after operation (P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(3) Prolo lumbar function score : Prolo scores of the patients of the multimodal analgesia group were obviously higher than that of control group at 1,3,7 days after operation (P ＜0.05).There was no significant difference at the discharge between the two groups(P＞0.05).Conclusion Multimodal Analgesia is shown to safely provide excellent pain control and functional recovery.It can reduce visual analogue pain score and improve lumbar function after surgery.

Analysis of respiratory complications in 922 severely burned patients / 中华烧伤杂志

<p><b>OBJECTIVE</b>To discuss the distribution of the respiratory complications in severely burned patients and the prevention and treatment experience against them.</p><p><b>METHODS</b>Medical records of 922 adult patients with severe or extremely severe burn hospitalized in our burn ICU from January 2005 to December 2012 were screened and retrospectively analyzed, including patients transferred from other hospitals, patients with total burn area above 50% TBSA, the distribution and treatment of respiratory complications, and the mortality. Data were processed with chi-square test.</p><p><b>RESULTS</b>The constituent ratio of patients transferred to our hospital was 71.1% in 2007 and 40.2% in 2010, while it remained about 50.0% in the other years. The ratios of patients with total burn area larger than 50% TBSA and that of patients with respiratory complications (χ(2) = 2.637, P > 0.05) showed no significant changes each year. Among these 922 burn patients, 523 patients suffered respiratory complications, among which laryngeal edema (50.9%, 266 cases), pulmonary infection (21.6%, 113 cases), and ARDS (11.9%, 62 cases) were the main components, with no significant change each year (with χ(2) values respectively 6.132, 6.319, 0.016, P values above 0.05). Among the patients with respiratory complications, except for 36 were not treated actively, 487 were treated by ventilator among which 228 had undergone tracheostomy, and the constituent ratios in the 8 years were close. Fifteen patients died, with 2 died of laryngeal edema, 3 of ARDS, and 10 of sepsis or MODS as a result of sepsis.</p><p><b>CONCLUSIONS</b>Patients with severe burns were at high risk of respiratory complications, among which laryngeal edema was common, followed by pulmonary infection and ARDS. Prophylactic tracheostomy, mechanical ventilation, wound therapy, and anti-infection were all effective measures of prevention and treatment against these complications.</p>

Effects of lung protective ventilation strategy combined with lung recruitment maneuver on patients with severe burn complicated with acute respiratory distress syndrome / 中华烧伤杂志

<p><b>OBJECTIVE</b>To investigate the effects of lung protective ventilation strategy combined with lung recruitment maneuver on ARDS complicating patients with severe burn.</p><p><b>METHODS</b>Clinical data of 15 severely burned patients with ARDS admitted to our burn ICU from September 2011 to September 2013 and conforming to the study criteria were analyzed. Right after the diagnosis of acute lung injury/ARDS, patients received mechanical ventilation with lung protective ventilation strategy. When the oxygenation index (OI) was below or equal to 200 mmHg (1 mmHg = 0. 133 kPa), lung recruitment maneuver was performed combining incremental positive end-expiratory pressure. When OI was above 200 mmHg, lung recruitment maneuver was stopped and ventilation with lung protective ventilation strategy was continued. When OI was above 300 mmHg, mechanical ventilation was stopped. Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, variables of blood gas analysis (pH, PaO2, and PaCO2) were obtained by blood gas analyzer, and the OI values were calculated; hemodynamic parameters including heart rate, mean arterial pressure (MAP), central venous pressure (CVP) of all patients and the cardiac output (CO), extravascular lung water index (EVLWI) of 4 patients who received pulse contour cardiac output (PiCCO) monitoring were monitored. Treatment measures and outcome of patients were recorded. Data were processed with analysis of variance of repeated measurement of a single group and LSD test.</p><p><b>RESULTS</b>(1) Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the levels of PaO2 and OI of patients were respectively (77 ± 8), (113 ± 5), (142 ± 6) mmHg, and (128 ± 12), (188 ± 8), (237 ± 10) mmHg. As a whole, levels of PaO2 and OI changed significantly at different time points (with F values respectively 860. 96 and 842. 09, P values below 0. 01); levels of pH and PaCO2 showed no obvious changes (with F values respectively 0.35 and 3.13, P values above 0.05). (2) Levels of heart rate, MAP, CVP of all patients and CO of 4 patients who received PiCCO monitoring showed no significant changes at different time points (with F values from 0. 13 to 4. 26, P values above 0.05). Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the EVLWI values of 4 patients who received PiCCO monitoring were respectively (13.5 ± 1.3), (10.2 ± 1.0), (7.0 ± 0.8) mL/kg ( F =117.00, P <0.01). (3) The patients received mechanical ventilation at 2 to 72 h after burn, lasting for 14-32 (21 ± 13) d. At post injury day 3-14 (7 ± 5) d, lung recruitment maneuver was applied for 2-5 (3.0 ± 2.0) d. All 15 patients recovered without other complications.</p><p><b>CONCLUSIONS</b>Lung protective ventilation strategy combining lung recruitment maneuver can significantly improve the oxygenation in patients with severe burn complicated with ARDS and may therefore improve the prognosis.</p>

Effect of micro-ecological agent on the intestinal dysbacteriosis of patients with posterior lumbar spine surgery / 中国综合临床

Objective To investigate the effect of micro-ecological agent on the intestinal flora of patients with posterior lumbar spine surgery.Methods Seventy-two patients with lumbar spine surgery were selected as our subjects.Of them,42 patients with occurred the intestinal flora dysfunction were served as experimental group (group A),other 30 patients were as control group (group B).The levels of plasma endotoxin,plasma tumor necrosis factor-α (TNF-α),Interleukin 6 (IL-6) were detected before and after operation.The patients in group A were treated with micro-ecological agent Jinshuangqi.Collected stool samples at preoperative,postoperative first natural defecation (after 1-4 d),and compared intestinal flora difference and Bifidobacterium (B)/Enterobacteriaceae (E) value of two groups patients.Results The levels of plasma endotoxin in group A were (1.82 ±0.12),(2.29 ±0.15),(1.91 ±0.08) ng/L at before surgery,the 2nd and 7th day after surgery,and that in group B were(1.91 ±0.21),(2.35 ±0.16),(2.26 ±0.24) ng/L The TNF-α level in group A were (275 ±51),(309 ±45),(276 ±34) ng/L and that in group B were (269 ±48),(318±67),(297 ±53) ng/L at before surgery,the 2nd and 7th day after surgery.The IL-6 levels in group A were (138 ± 22),(159 ± 15),(137 ± 17) ng/L and that in group B were (159 ± 16),(187 ± 19),(174 ± 21) ng/Lat before surgery,the 2nd and 7th day after surgery.The repeated measured repeated measures analysis of variance showed that among three indexes of plasma endotoxin,TNF-α,IL-6 levels,differences of between group and interaction were statistically significant (P ＜ 0.05),but there was no significant difference within groups (P＞ 0.05).The levels of plasma endotoxin,TNF-α,IL-6 decreased after surgery ware gradually decreasing with hospitalization prolonged.There was significant difference between before surgery and at the 2nd,7th day after surgery(P ＜ 0.05),and there was significant difference between the 2nd and the 7th day after surgery(P＜ 0.05).At the 2nd day after surgery,there was significant difference between group A and group B in terms of the level of plasma endotoxin,TNF-α,IL-6.At the 7th day,the levels of plasma endotoxin,TNF-α,IL-6 were slowly decreased in group A,and there were significant difference compared to group B (P ＜ 0.05).The numbers of intestinal Bifidobacterium,Bacteroides,and B/E values of group A were decreased after surgery compared to group B((9.17 ±0.54) lg cfu/g vs.(10.01 ± 0.75) lg cfu/g,(9.23 ± 0.47) lg cfu/g vs.(10.09 ± 0.81)lg cfu/g,(1.01 ± 0.16) vs.(1.20 ± 0.11)),and the difference was significant (P =0.031,0.042,0.029respectively).The levels of Enterobacter and Enterococcus in group A were (9.11 ± 1.02) lg cfu/g,(7.80± 1.02) lg cfu/g,higher than that of group B ((8.81 ± 0.89) lg cfu/g,(7.29 ± 0.98) lg cfu/g(P =0.037,0.043)).There was no significant difference between two groups in terms of small clostridium and lactobacillus (P ＞ 0.05).After treated with micro-ecological agent Jinshuangqi,the levels of intestinal Bifidobacterium,Bacteroides,and B/E value at was increased compared to before treated in group A (Bifidobacterium:(13.01±0.87) lg cfu/g vs.(9.17 ±0.54) lg cfu/g; Bacteroides:(14.12 ±0.75) lg cfu/g vs.(9.23 ±0.47)lg cfu/g; B/E value:(1.28 ± 0.45) vs.(1.01 ± 0.16) ;P =0.045,0.034,0.038 respectively).No significant difference was seen in terms of the levels of Enterobacter,Enterococcus,small clostridium and lactobacillus between two groups(8.71 ±0.91) lg cfu/g vs.(9.11 ± 1.02) lg cfu/g,(7.01 ±0.54) lg cfu/g vs.(7.80± 1.02) lg cfu/g,(5.23 ± 1.04) lg cfu/g vs.(5.15 ± 0.89) lg cfu/g,(6.71 ± 1.04) lg cfu/g vs.(6.53± 0.86) lg cfu/g respectively; P ＞ 0.05).Conclusion Posterior lumbar operation patients with intestinal dysbacteriosis often associated with endotoxemia and inflammatory reaction,the levels of bifidobacteria,Bacteroides intestinal Enterobacteriaceae decrease while Enterococcus,opportunistic pathogens increase,and intestinal microbial colonization resistance decrease.Micro-ecological agent Jinshuangqi treatment can ease the body's endotoxemia and inflammatory response,improved lumbar surgery intestinal flora after surgery,and beneficial to rebuild the intestinal microflora balance.

One-stage posterior and anterior surgical management of thoracolumbar spinal tuberculosis / 中国综合临床

Objective To explore the therapeutic efficacy of posterior internal fixation and anterior debride-ment with autogenous bone grafts at one stage on tuberculosis of thoracic or lumbar spine . Methods 16 cases of thoracic or lumbar spinal tuberculosis patients were treated with combined anterior (radical debridement and bone autograft) and posterior (instrumentation) surgeries in one stage between September 2003 and September 2007. The degree of the kyphosis (Cobb angle) was measured and the interbody fusion was observed preoperatively and postop-eratively. The ASIA grading system was used to assess the neurological status. Results All patients were followed up for 10 months to 36 months,on average of 12 months. All patients showed sucessful interbedy fusion,but Cobb angle was not progressed. No recurrence or wound infection was found. 6 cases all got nerve function recovery. Conclusion Thoracic or lumbar tuberculosis treated with this surgical technique can achieve stable internal fixation and a high satisfactory rate with restoring the spinal stability, arresting the disease early, providing early fusion, correcting the ky-pbosis particularly.
