ABSTRACT

Objective To develop a new method to measure pleural effusion volume by ultrasound in critically ill patients. Methods Forty-six critically ill patients admitted to emergency ICU were involved.The height of effusion (H),area of effusion at the middle section (S), thickness of effusion at middle-back line (T1) and posterior axillary line (T2) were measured by ultrasound in supine position at the end of expiration. The measured volume of pleural effusion (Vc) was calculated by H×S,and the actual volume of drainage (V) within 2 hours was also recorded. The correlation of actual volume of pleural effusion (V)with effusion height (H) ,thickness (T1, T2), area (S) and the calculated volume (Vc) were analyzed to decide the most accurate index and method. Results There was much better correlation between actual volume of effusion and S, (H & S), Vc, than these between V and T1 ,T2, H in all patients and subgroup, Vc had good correlation with V and very close to V(the average difference was 56 ml) when the actual volume was less than 500 ml,there was no difference[(417 ± 94)ml vs (402±95)ml, t = 1.095, P = 0. 285]. Both Logistic regression analysis and receiver operating characteristic (ROC) curve showed S was the most reliable index to predict the actual volume to exceed 500 ml,400 ml,and 300 ml when compared with H,S,T1 and T2. The corresponding threshold was 30.3 cm2 , 28.3 cm2 and 23. 1 cm2 , with the sensitivity and specificity of 0. 77 and 0. 88,0.72 and 1.0,0.95 and 1.0, respectively. Conclusions This new method based on measuring the area of effusion by ultrasound is more efficient and reliable than those traditional ones to measure the volume of pleural effusion. It's clinically valuable and easy to perform, and deserves broad application.

ABSTRACT

Objective To investigate the dynamic change of serum myoglobin and assess its relation with injury severity in multiple trauma patients. Methods The concentration of serum myoglobin in 41 multiple trauma patients (ISS ≥16 points) was detected at days 1,3,7 and 14 after injury. In the meantime, injury severity score ( ISS), Glasgow coma score ( GCS), simplified acute physiology score Ⅱ( SAPS Ⅱ ), percentage of the injured muscle and soft tissue to entire body, shock on admission and ultimate outcomes were recorded at day 1 after injury. All patients were divided into ISS ≥25 group or ISS < 25 group, survival group or death group based on the injury severity and ultimate outcomes. The dynamic changes of the serum myoglobin were observed and compared between the groups. The correlation of the serum myoglobin concentration with ISS, GCS, SAPS Ⅱ score, shock and the percentage of injured muscle and soft tissue was investigated. Results The serum myoglobin concentration in ISS ≥ 25group was decreased more slowly than that in the ISS < 25 group, with higher concentration of the serum myoglobin concentration in the ISS ≥ 25 group than that in the ISS < 25 group at all time points. The serum myoglobin concentration in the death group was increased first, then slowly declined and reached peak at day 3. While in survival group, the serum myoglobin concentration was continuously decreased, with lower serum myoglobin concentration than that in the death group at all time points. The serum myoglobin concentrations were positively correlated with the SAPS Ⅱ score at all time points, with ISS at days 7 and 14, with the percentage of the injured area at day 1 and with the shock at days 1 and 3, while the serum myoglobin concentration was negatively correlated with GCS at days 3,7 and 14. Conclusions The dynamic changes of the serum myoglobin concentration in multiple trauma patients may reflect the severity,trends and prognosis of the injury, and hence can be used as effective index for monitoring the disease.

ABSTRACT

Objective To explore the determinant factors influencing the constituent parts of radiological examination in severe trauma patients so as to provide scientific basis for optimized strategy of radiological examination. Methods A prospective study was carried out from April to July 2010 in a tertiary hospital. Clinical data of 60 severe trauma patients admitted to emergency department and ICU were recorded. The type, number and site of trauma under radiological examination were described and compared among different stages of treatment. The correlation between number of radiological examinations and age, number of injured site, injury severity score (ISS), Glasgow Coma Scale (GCS), ICU stay and overall length of hospital stay were analyzed. Results (1) The majority of radiological examinations in 60 patients were radiography and CT, with a corresponding median number of 6.0(3.0~ 11.0, IQR)and 10.0(8.0 ~ 13.8, Qr) times per patient. (2) The numbers of radiography examinations requested in emergency room, emergency ICU and general ward were quite approximately equal (x2 =4.043 ,P =0. 132), while CT examinations were mainly requested in emergency room and emergency ICU (x2 = 20. 274 , P < 0. 001). (3) The numbers of radiological examinations requested for different sites of injury were quite significantly different between radiography and CT during different stages of treatment (x2 = 114.609, 75.932, P < 0.01). (4 ) The number of CT scan requested was positively correlated with number of injured site, ISS, ICU and overall length of hospital stay (r =0.273,0.369,0.523,0.417,all P <0.05). Conclusions The sum of radiological examinations in severe trauma patients was great mainly in radiography and CT, and CT was more predominantly requested. The number of CT scans examinations was positively correlated with severity of injury and length of ICU stay. Further study is warranted to optimize radiological examination in severe trauma patients.

ABSTRACT

Objective To study the value of focused abdominal sonography for trauma (FAST) used by emergency doctor in emergency department. Method It's a prospective,double-blinded and controlled study from June 2008 to October 2009. A total of 97 casualties with severe multiple trauma, 72 male and 25 female aged from 14 to 88 years old with average age of (41 ± 16) ,admitted to emergency department were enrolled, and the bedside focused abdominal sonography for trauma was performed by emergency doctor. It was diagnosed as positive if free fluid was detected in abdomen or pericardium. The severe injury scores (ISS) were from 14 to 38 with average score of (23.2±9.3). The criteria of inclusion were age over 14 years old, injury happened within 12 hours and casualties admitted directly into emergency room. The criteria of exclusion were death of patients within 2 days without CT scanning of abdomen and exploration of abdomen with laporotomy, and operations directly determined by using FAST without conventinal sonographic examination. The FAST was compared with CT and conventional sonography judged by the findings observed during operation. Results The examination with FAST was completed in (3.18±0.79) min, whereas that with conventional sonography was (16.63t4.62) min(t = 28.61,P <0.001). The FAST was positive in 11 cases and negative in 86 cases, whereas the conventional sonography was positive in 13 cases and negative in 84 cases ( P = 0.5). There were 4 false negative findings in FAST resulting in 73% sensitivity, 100% specificity, 95.3% negative predictive value, 4.6% false negative rate, 100% positive predictive value, 0% false positive rate and 95.9% accuracy. Conclusions The emergency doctors are able to operate the FAST well for casualties with multiple trauma in emergency department after proper training.

ABSTRACT

Objective To evaluate the value and significance of bedside ultrasound in diagnosis of lung atelectasis/consolidation in multiple trauma patients with mechanical ventilation.Methods Bedside thoracic ultrasound and chest computed tomography(CT)were performed in 81 multiple trauma patients with mechanical ventilation admitted to the emergency intensive care unit(EICU).CT result was regarded as the "golden standard" to evaluate the value of ultrasound in diagnose lung atelectasis/consolidation.At the same time,the ultrasound was used to dynamically monitor the lung recruitment effect of the therapeutic measures.Results CT detected 154 regions of lung atelectasis/consolidation of 324 lung regions in 81 patients,while ultrasound detected 126 regions that were divided into 87 complete regions and 39 incomplete regions according to different sonogram in the breathing cycle.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of ultrasound were 81.8%,100%,100%,85.9% and 91.4% respectively.A concordance test showed a very high concordance between ultrasound and CT,with a Kappa coefficient of 0.825(P=0.031).Ultrasound found that 39 regions with incomplete lung atelectasis/consolidation were completely recruited and 62 out of 87 regions with complete lung atelectnsis/eonsolidatian gained visible recruitment within three days after different therapeutic measures,with total effective rate of 80.2%.Conclusion Bedside ultrasound can continuously monitor and guide the therapeutic measure to recruit the lung and is a convenient,safe,direct-viewing and accurate method for diagnosis of lung atelectasis/cansolidation in multiple trauma patients with mechanical ventilation.

ABSTRACT

Objective To identify the potential risk factors affecting mortality rate of ALl in severe trauma population. Method It was a retrospective cohort study treating trauma as a single cause for emergency depart-ment (ED)) and emergency intensive care unit (EICU) admissions. Eighteen potential risk factors affecting the mortality of ALI were examined by univariate and multivariate logistic analyses in these severe trauma patients. Re-sults There were 343 severe trauma patients with post-traumatic ALI admitted to ED and EICU the Second Affili-ated Hospital Medical College,Zhejiang University,during the study period. The five risk factors that affected the mortality with unadjusted odd ratios (ORs) and 95% confidence intervals (CIs) were (1) APACHE Ⅱ score, (2)duration of trauma, (3) age, (4) aspiration of gastric contents, and (5) DIC. Specific risk factors also affected different patients subpepulations at different degrees. Conclusions Factors of APACHE Ⅱ score and aspiration of gastric contents that can predict the mortality of ALl may exist in the early stage of trauma. Duration of trauma and DIC that greatly affect the short- and long-term development of ALI deserve special attention. Elderly patients (aged beyond 65 years) are the independent risk factor for the secondary sepsis and deterioration of pulmonary function. Patients with these risk factors need aggressive supportive care as early as possible in order to prevent fur-ther aggravation.

ABSTRACT

Objective To approach the changes of serum insulin and peptide C and determine their relationship with inflammatory reaction in patients with severe multiple trauma. Methods The serum insulin, peptide C, tumor necrosis factor (TNF)-α, interleukin (IL)-10, C reactive protein (CRP) were detected in 30 patients with severe multiple trauma at days 1,3 and 7 after trauma to analyze the dynamic changes of serum insulin and peptide C and their correlations with Acute Physiology and Chronic Health Evaluation Ⅲ ( APACHE Ⅲ), cytokines and CRP. The changes of cytokines and CRP were also compared with those of serum insulin and peptide C in patients with different outcomes. The changes of serum insulin and peptide C of 35 healthy subjects were detected and used as control. Re-sults The serum insulin and peptide C levels of patients were higher than those in control group at each time point after trauma, with remarkably positive correlation with APACHE Ⅲ. Whether the serum glu-cose and age were controlled or not,serum insulin and peptide C were positively correlated with IL-10 at each time point and with TNF-α and CRP at days 3 and 7. The levels of serum insulin, peptide C and IL-10 were decreased with time in both groups with different outcomes. Meanwhile, the levels of TNF-α and CRP were decreased in the survival groups but increased in the death groups. The levels of above indices in death group were significantly higher than survival groups at the same time point. Conclusions The increasing of serum insulin and peptide C is correlated with inflammatory reaction after severe multiple trauma. The dynamic changes of both indices can either reflect injury severity or be used as an effective index in dynamically monitoring anti-inflammatory degree of the organism.

ABSTRACT

Objective To investigate the relationship between serum cholinesterase(ChE) and acute-phase proteins in patients with multiple trauma, then to evaluate their significance to judge prognosis. Method It's a prospective observation study. Patients with multiple trauma admitted to emergency intensive care unit,Second Af-filiated Hospital, Zhejiang Universieg, school of medicihe within 24 h after trauma from Oct. 2005 to Oct. 2007 were enrolled. And those with chronic liver disease, touching orgnaophosphorus, active tuberculosis, tumor, in-fection of major organ before trauma, liver injury or age < 18 year were excluded. Among 81 patients, 57 were male and24 female. The average age was (46±18) years, and the average injury severity score was (34.0±11.9).Seventy six healthy were selected as controls, 53 male and 23 female, with an average age of (44±16)years. The exclusion standards were the same as those in patients. Both groups had same gender proportion and age. Senum ChE and acute-phase proteins(APP) including albumin(ALB), prealbumin(PAB), transferrin(TRF),C-reactive protein(CRP) in patients were detected at 1, 3, 7 d after trauma. The acute physiology and chronic health evaluation Ⅲ (APACHEⅢ) was recorded simuhancously. Serum ChE, ALB, PAB, TRF, CRP in the controls were also detected. All of these indexes in the controls were compared with thoses in patients by t test or rank surn test. The dynamic changes of serum ChE and APPs in patients were analyzed by one way repeated mea-sures ANOVA. The relationships between serum ChE and those APPs and the relationships between APACHE Ⅲ and these indexes were analyzed by Pearson correlation analysis. We also compared these indexes between patients with different outcomes by t test or rank sum test. The values of serum ChE and those APPs to judge prognosis were evaluated by logistic regression analysis. Results Patients had lower serum ChE, ALB, PAB, TRF and higher CRP than the healthy at 1, 3, 7 d post trauma. Serum ChE activity in patients was reducod over 25% (42.3%~50.2%) than that in the healthy, and showed a tendency to decrease after trauma, which resembled PAB and TRF. Serum ChE was positively correlated with ALB, PAB and TRF at 1, 3, 7 d, and negatively correlated with CRP at 3, 7 d. At 1, 3, 7 d post trauma, APACHEⅢ in patients was negatively correlated with serum ChE and TRF, but negatively correlated with ALB only at 1 d, and negatively correlated with PAB only at 1,7 d, and posi-tively correlated with CRP only at 7 d. Non-survivors had lower serum ChE activity and TRF than survivors at 1,3,7 d after trauma, but had lower ALB only at 7 d after trauma and had lower PAB only at 1,7 d after trauma than survivors, and had higher CRP than survivors only at 7 d after trauma. Logistic regression analysis showed serum ChE and PAB were the only two independent risk factors to judge prognosis. Conclusions Serum ChE may be in-cluded as negative acute-phase protein, and is better than other APPs in reflecting injury severity and prognosis in patients with multiple trauma.

ABSTRACT

AIM:Many studies have documented an anabolic effect of hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, statins, on undisturbed bone. Reports of their effects on fractured skeleton were limited. A study was therefore conducted to check the effects of statins on fracture healing. METHODS: Simvastatin (10 mg?kg-1?d-1) was injected subcutaneously to tissue overlying the site of fractured tibiae of ovariectomized rats for a treatment period of 5 d. Vehicle reagent was used as control. Healing quality was evaluated at 1, 2 and 4 weeks after fracture. RESULTS: Compared with vehicle group, callus cross section area in simvastatin treated rats were significantly enlarged by 21.3% (P
