RESUMO
Objective:To compare the clinical efficacy between a single palmar lateral transverse approach and the modified Henry approach in the locking plate fixation for distal radius fractures.Methods:A retrospective study was conducted to analyze the data of 82 patients with distal radius fracture who had undergone locking plate fixation through either a single palmar lateral approach or the modified Henry approach between January 2016 and December 2022 at Department of Traumatic Orthopaedics, Taihe Hospital, Affiliated to Hubei University of Medicine. There were 25 males and 57 females, with an age of (53.8±12.7) years. Based on the difference in surgical approach, the patients were divided into a single transverse approach group ( n=42) and a modified Henry approach group ( n=40). The 2 groups were compared in terms of injury cause, injury location, time from injury to surgery, AO fracture classification, tourniquet time during surgery, incision length, fracture reduction, Patient and Observer Scar Assessment Scale (PSAS & OSAS) and Disability of the Arm, Shoulder, and Hand (DASH) score at the last follow-up, and complications after surgery. Results:There were no statistically significant differences in the baseline characteristics between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (8.2±3.5) months. Follow-ups revealed one case of injury to the palmar cutaneous branch of the median nerve but no other complications like infection, non-union, internal fixation failure, or tendon injury in the single transverse approach group. The single transverse approach group was significantly superior over the modified Henry approach group in incision length [(2.4±0.9) cm versus (5.3±1.6) cm], OSAS (8.1±4.2 versus 10.3±5.7), and PSAS (10.1±5.8 versus 14.7±6.4) ( P<0.05). There were no significant differences between the 2 groups in tourniquet time, fracture reduction quality, and DASH score at the last follow-up ( P>0.05). Conclusion:In locking plate fixation for distal radius fractures, in comparison with the modified Henry approach, a single palmar lateral approach is more minimally invasive so that more aesthetically pleasing outcomes can be achieved to facilitate patients' rapid return to work and society.
RESUMO
AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.
RESUMO
Objective:To detect the changes in the biological activity and expression of long-chain non-coding RNA-p21 (lncRNA-p21) in human lens epithelial cells HLE-B3 damage induced by hydrogen peroxide.Methods:HLE-B3 cells were divided into normal control group and hydrogen peroxide group, which were cultured in normal culture medium and culture medium containing 200 μmol/L hydrogen peroxide for 24 hours, respectively.Cell viability was determined by MTS colorimetric method.Cellular reactive oxygen species (ROS) level was detected using ROS assay kits.Cell apoptosis was tested by flow cytometry.Cell Caspase-3 activity was detected using Caspase-3 assay kit.Expressions of Bax and Bcl-2 proteins related to cell apoptosis were determined by Western Blot.Cell cycle distribution was determined by flow cytometry.Cell proliferation ability was detected by EDU proliferation assay kit.The expression of lncRNA-p21 in cells was detected by real time fluorescence quantitative polymerase chain reaction (PCR).The localization of lncRNA-p21 in cells was detected by fluorescence in situ hybridization.Results:The ROS content of cells in hydrogen peroxide group was (4.65±0.38), significantly higher than (1.00±0.01) of normal control group, and the difference was statistically significant ( t=16.66, P<0.05).Compared with the normal control group, the cell apoptosis rate was significantly increased, the activity of Caspase-3 was enhanced, and the relative expression of Bax was significantly increased in the hydrogen peroxide group, with statistically significant differences ( t=20.69, 39.80, 12.73, all at P<0.05).Compared with the normal control group, the proportion of G2 phase cells in the hydrogen peroxide group significantly increased, showing a statistically significant difference ( t=23.10, P<0.05).The EDU-positive cell rate of hydrogen peroxide group was (25.41±6.99)%, significantly lower than (50.58±9.15)% of normal control group ( t=6.559, P<0.05).The relative expression level of lncRNA-p21 in the hydrogen peroxide group was 2.36±0.29, significantly higher than 1.02±0.02 in the normal control group ( t=7.893, P<0.05).The fluorescence in situ hybridization experiments indicate that lncRNA-p21 was localized in the cytoplasm. Conclusions:In the oxidative stress model induced by hydrogen peroxide, the proliferation ability of lens epithelial cells significantly decreases, the apoptosis level significantly increases, and the expression levels of ROS and lncRNA-p21 enhances.lncRNA-p21 may be involved in the oxidative stress injury process of lens epithelial cells.

RESUMO
Cerebral amyloid angiopathy(CAA)is a small vascular disease caused by the deposition of amyloid protein in the vascular wall, mainly involving the cortical and leptomeningeal arterioles and capillaries.The main pathological and clinical manifestations are lobar hemorrhage, cerebral microbleeds, cortical superficial siderosis, subarachnoid hemorrhage, cortical infarction, white matter abnormalities, CAA-related autoimmune meningoencephalitis and dementia.Patients with CAA are prone to spontaneous cerebral hemorrhage.For CAA patients, the anticoagulant therapy for prevention of cardioembolism of artrial fibrillation or intravenous thrombolytic therapy for acute ischemic stroke may increase the chance of cerebral hemorrhage and lead to aggravation of the disease.Therefore, the risk of hemorrhage associated with CAA needs to be evaluated before antithrombotic therapy.CAA-related inflammation is a critical condition.Corticosteroids and immunosuppressive agents are effective treatments.Early diagnosis and treatment can significantly improve the prognosis.
RESUMO
Objective:To explore the structural and functional alterations of related brain regions in patients after cardiopulmonary resuscitation (CPR) by brain magnetic resonance imaging (MRI).Methods:A single-center, observational, cross-sectional study design was used. Patients who had brain MRI scans during hospitalization between July 2020 and July 2021 in Emergency Department of the First Affiliated Hospital of Nanjing Medical University and had good neurologic outcomes were consecutive enrolled in this study. The healthy control (HC) group consisted of age- and sex-matched volunteers. The demographic and clinical data were recorded. The modified Rankin Scale (mRS) was used to check the recovery and degree of continued disabilities when patients performed MRI. Montreal cognitive assessment (MoCA) was used to assess cognitive functions. The analyses of voxel-based morphometry (VBM) and fractional amplitude of low-frequency fluctuation (fALFF) were conducted. After data preprocessing, comparison of gray matter volume (GMV) and fALFF values between the case group and HC group were carried out, and the information of different brain regions was obtained. Partial correlation analyses were performed to evaluate the correlation between the image parameters of different clusters and clinical parameters.Results:Totally 13 patients were enrolled in this study and 13 were in the HC group. All patients achieved good neurologic outcome; mRS was 3 in 1 case, 2 in 3 cases, and 1 in 5 cases during MEI examination. The case group showed significantly lower MoCA score compared with the HC group ( P<0.001). There were significantly decreased GMVs in the right inferior frontal gyrus, superior temporal gyrus, left superior temporal gyrus, and transverse temporal gyrus in the case group. The patients showed significantly decreased fALFF values in the left postcentral gyrus and precentral gyrus, while increased fALFF values in the right putamen than the HC group (voxel-level P<0.001 and cluster-level P<0.05 with GRF correction). In addition, mean fALFF value in the right putamen was negatively correlated with MoCA score in the case group ( r=-0.710, P=0.021). Conclusions:Patients after CPR may have GMVs and neuronal spontaneous activity changes in some brain regions, and VBM and fALFF methods can be used to objectively evaluate the impaired brain functional activity in patients after successful CPR.
RESUMO
Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.
RESUMO
Objective:To explore the clinical value of urine semi-quantitative colorimetry by sodium dithionite reduction method in the diagnosis and treatment of diquat poisoning.Methods:The data of 49 patients with acute diquat poisoning treated in the First Affiliated Hospital of Nanjing Medical University from December 3, 2020 to November 23, 2022 were retrospectively analyzed, the correlation between urine colorimetric results and plasma diquat concentration was observed, and the predictive value of urine colorimetric results for target organ damage and prognosis were evaluated.Results:There was a significant correlation between urine colorimetric results and plasma diquat concentration, the correlation coefficient was r=0.89, P <0.01. The cut-off value of urine colorimetry for the predicting the damage of gastrointestinal tract, liver, kidney, and central nervous system injury were 2.5, 3.5, 3.5, 5.5, respectively; in which the urine colorimetric results showed the highest sensitivity in predicting digestive tract injury [ AUC 0.93 (95% CI:0.89-1.00)]. The cut-off value of urine colorimetry for the prognosis of death was 4.5, the positive predictive value was 64.2%, and the negative predictive value was 95.2%. Conclusions:The urine semi-quantitative method can be used for rapid prediction of the plasma diquat concentration range on admission. The urine colorimetry results can also effectively predict the occurrence of organ injury and clinical outcome related to diquat poisoning, which provides evidence for the clinical diagnosis and therapy.
RESUMO
Objective:To explore the clinical characteristics of poisoned patients with poisons purchase online.Methods:A retrospective case-control study was conducted on poisoned patients purchased poisons online from 1st January 2021 to 31th May 2022 in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University. The clinical data including sex, age, way of medical treatment, cause of poisoning, exposure routes, category of toxic drugs, gastric lavage, toxic detection and prognosis of patients were collected and compared with those patients obtained poisons at stores as the control group.Results:Totally 318 poisoned patients were included in this study, of which 44 (13.8%) were obtained poisons online. Compared with the patients obtained poisons at stores, the patients obtained poisons online were younger ( P<0.001), and had higher proportion of suicide intention ( P=0.006), more oral route exposure ( P=0.029), and more proportions of receiving gastric lavage before transfer to the hospital ( P=0.001). Pesticides and fertilizers with organic heterocycles were the main types of poisons in the online group, and there was no statistical difference in the distribution of poisons compared with the control group. Mixed drug poisoning was the leading cause in both online group (27.8%) and control group (38.8%) in drug overdose poisoned types, followed by dextromethorphan (16.7%) and estazolam (15.5%) in the online group. Conclusions:Young people are the main group getting poisons through the Internet. Health education should be strengthened for this group, and online shopping platforms should pay attention to the poisoning risk of potential overdose drugs or poisons transactions.
RESUMO
Objective:To evaluate the therapeutic effect of hemopurification on acute chlorfenapyr poisoning according to the blood concentration of chlorfenapyr and to provide experience for clinical treatment.Methods:Two patients who presented to our Emergency Department following an ingestion of chlorfenapyr and then were treated with hemopurification in 2022 were included. The concentrations of chlorfenapyr and its highly toxic metabolite tralopyril were dynamically monitored, and the clinical data of the patients were collected.Results:Case 1 was given hemoperfusion for the first time 13 hours after ingestion. During l hour hemoperfusion, the tralopyril decreased by 28.82%. The concentration increased and exceeded the pre-perfusion level after 2 hours of hemoperfusion. After three times of hemoperfusion, the concentrations of chlorfenapyr and tralopyril were still higher than those before the first time, reaching 248 ng/mL and 1 307 ng/mL respectively. The concentration of chlorfenapyr showed a downward trend after 130 h, and the tralopyril in blood reached the peak 3 164 ng/mL at 130 h and decreased to 2 707 ng/mL at 178 h. In case 2, the blood chlorfenapyr and tralopyril concentration was 392 ng/mL and 7 598 ng/mL respectively 150 hours after ingestion. The blood chlorfenapyr concentration decreased by 37.75% respectively after first hemoperfusion, and the tralopyril concentration decreased by 38.02% respectively. During 85 hours of continuous veno-venous hemodiafiltration (CVVHDF), the concentration of tralopyril was maintained at 4 234~6 410 ng/mL. Case 1 was followed up to 12 days and lost follow-up. Case 2 died and the survival time was 247 hours.Conclusions:Hemoperfusion can scavenge tralopyril, but CVVHDF has poor scavenging ability for tralopyril. And the apparent volume of distribution (Vd) of chlorfenapyr and tralopyril are large. After ingestion, chlorfenapyr spreads to various tissues quickly, and it is easy to accumulate in the adipose tissue. The chlorfenapyr in the tissue slowly is released back to the blood and stays in the blood for a long time. The peak concentration of chlorfenapyr appeared earlier than that of tralopyril. Clinicians should pay attention to the early removal of toxins from the digestive tract.
RESUMO
Objective:To describe the current situation of gastric lavage operation and put forward measures for improvement by analyzing the clinical characteristics of 294 patients with gastric lavage in Poisoning Treatment Center of The First Affiliated Hospital of Nanjing Medical University.Methods:The clinical data of 294 patients with acute poisoning and gastric lavage from 2019 to 2021 were collected and analyzed retrospectively, and the related parameters (poison type, gastric lavage volume, poisoning to gastric lavage time, etc.) of each year were compared.Results:A total of 653 poisoning patients underwent gastric lavage from 2019 to 2021, with an average age of (44.2 ±20.1) years, and 134 (45.6%) were male. The main causes of gastric lavage were pesticide poisoning (52.72%) and drug poisoning (42.86%). The volume of gastric lavage was less than 10 L for 43.8% of patients and 10-20 L for 32.7% of patients. Patients with gastric lavage within 60 min after ingestion of poison accounted for 45.3%, followed by 25.8% within 61-120 min. The in-hospital mortality rate was 17.7%. The common complications of gastric lavage were: the incidence of gastrointestinal bleeding (55/121, 45.5%), the incidence of aspiration pneumonia (54/140, 38.6%), and the incidences of electrolyte disorder (21% of low potassium, 29% low calcium, and 10.0% low sodium). Compared with the groups in different years, the proportion of gastric lavage in poisoning was 58.85% vs. 46.60% vs. 32.41%, which decreased year by year, with statistical difference ( P <0.05). And there was no difference in the period from ingestion to gastric lavage and gastric lavage fluid volume. There was an increasing trend in poison types between diquat and other insecticides, but there was no statistical difference. Conclusions:From 2019 to 2021, the most common causes of acute gastric lavage were pesticide poisoning and drug poisoning, and the proportion of diquat and other pesticides showed an overall upward trend. A majority of the patients (71.1%) had gastric lavage within 2 h, and 76.5% of the patients had less than 20 L gastric lavage fluid. In the future, we will further control the amount of gastric lavage fluid and pay attention to the gastric lavage operation of new insecticide poisoning.
RESUMO
Objective:Early identification of ischemic stroke patients with large vessel occlusion can improve referral efficiency and shorten reperfusion time. The purpose of this study was to analyze the characteristics of patients with large vessel occlusion and identify factors that could predict large vessel occlusion.Methods:The clinical data of 432 patients with ischemic stroke treated through emergency green channel were retrospectively analyzed, and the differences between the large vessel occlusion group (LVO group) and the non-large vessel occlusion group (non-LVO group) were compared, and two independent risk factors of the LVO group were screened out by logistics regression analysis: baseline NIHSS score and D-dimer value. The predicted cutoff values of NIHSS score and D-dimer were further determined by the receiver operating characteristic (ROC) curve.Results:A total of 432 patients with ischemic stroke had complete imaging data, with a mean age of 68.5±12.4 years, including 275 (63.7%) males, and 245 (56.7%) in the LVO group and 187 (43.3%) in the non-LVO group. Age, hemorrhagic transformation, thrombolytic therapy, endovascular treatment, atrial fibrillation, baseline NIHSS score [14.0 (6.0-20.0) vs. 3.0 (1.0-6.0), P<0.05], and D-dimer value at admission [0.9(0.4-2.3) mg/L vs. 0.3 (0.2-0.5)mg/L, P<0.05] were statistically significant different between the two groups. Multivariate Logistic regression analysis showed that higher baseline NIHSS score( OR=1.22,95% CI: 1.17-1.27)and higher D-dimer value( OR=3.10,95% CI: 2.14-4.47)were independent risk factors for large vessel occlusion. Baseline NIHSS score combined with D-dimer value was a good predictor of large vessel occlusion(AUC 0.85 [0.81-0.89]). ROC curve suggested that NIHSS score >6.5 and D-dimer >0.57 mg/L were the cutoff values for predicting large vessel occlusion. Conclusions:Higher baseline NIHSS score and D-dimer value are valuable for early prediction of large vessel occlusion, patients with NIHSS score >6.5 points and D-dimer >0.57 mg/L should be promptly transported to an advanced stroke center for treatment.
RESUMO
Objective:To evaluate the outcome of the patients receiving dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) delivered by first-responders who witnessed the out-of-hospital cardiac arrest (OHCA) before the Emergency Medical Service (EMS) arrived.Methods:We performed a search of the relevant literature exploring major scientific databases. We assessed the quality of the included cohort study according to the Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. Meta-analysis was performed on three outcome indicators (recovery of spontaneous circulation survival to hospital discharge and survival with favourable neurologic outcome) using the Revman5.3 software.Results:A total of 21 studies with 349 822 patients were selected for the meta-analysis, including 182 125 patients in the DA-CPR group and 167 697 in the CPR-only group. The meta-analysis showed no significant difference between the DA-CPR and CPR-only groups in ROSC [ RR=1.10, 95% confidence interval ( CI): 0.94-1.29, P=0.24], survival to hospital discharge ( RR=1.10, 95% CI: 0.90-1.34, P=0.34) and survival with favourable neurologic outcome ( RR=1.01, 95% CI: 0.79-1.28, P=0.97) of the patients in America, Japan and Korea. However, there was a significant difference between the DA-CPR and the CPR-only groups in ROSC ( RR=2.61, 95% CI:1.53-4.46, P=0.0005), survival to hospital discharge( RR=6.08, 95% CI: 1.84-20.04, P=0.003), and survival with favourable neurologic outcome( RR=9.76, 95% CI: 1.87-51.02, P=0.007) of the patients in China. Conclusions:The overall effect of DA-CPR is significantly different for each country. In detail, DA-CPR offers a survival advantage (Return of spontaneous circulation, survival to hospital discharge and survival with favourable neurologic outcome) over CPR alone in China but no advantage in developed countries.
RESUMO
Previous studies believe that oligometastasis has unique biological characteristics. Early active treatment for patients with oligometastatic prostate cancer can delay disease progression and improve survival. However, the current definition of oligometastasis is still unclear, and its optimal treatment is still a major concern of the medical community. This article reviewed recent research progresses in term of the definition and comprehensive treatment strategy of oligometastatic prostate cancer.
RESUMO
Objective:To investigate the implementation status of sepsis hour-1 bundle strategy for patients with septic shock in emergency department.Methods:A total of 116 septic shock patients admitted to the emergency department from January 2020 to December 2020 were included in this prospective study, and the implementation of sepsis bundles and the clinical outcomes of patients were recorded.Results:Among 116 patients, 20 cases (17.2%) had lactic acid monitored within 1 h, 20 cases (17.2%) had blood culture before antibiotics, 82 cases (70.1%) received broad-spectrum antibiotics, 16 cases (13.8%) received fluid resuscitation ≥30 ml/kg, and 57 cases (49.1%) received vasoactive drugs during resuscitation. Finally, the sepsis hour-1 bundle strategy was fully implemented only in 13 cases (11.2%). Compared with the group with incomplete implementation of sepsis hour-1 bundle strategy, the volume of fluid recovery in the group with full implementation was significantly increased [33.7 (30.0,37.5) vs. 8.9(7.3,10.8) ml/kg, Z=-4.78, P<0.001], mean artery blood pressure significantly increased [70.0 (70.0,76.7) vs. 67.7 (61.7,76.7)mmHg(1 mmHg=0.133 kPa) , Z=-2.00, P<0.001], and lactic acid significantly decreased [3.0 (2.0,3.2) vs. 4.4 (3.7,7.2) mmol/L, Z=-2.76, P=0.006]. However, there were no significant differences in ICU mortality, in-hospital mortality and 28-day mortality between the two groups ( P>0.05). Conclusions:Septic shock patients in emergency department have poor compliance with the implementation of sepsis hour-1 bundle strategy, and relevant management training should be strengthened.
RESUMO
Objective:To investigate the predictive value of platelet dynamics on the prognosis of 28-day in patients with extracorporeal membrane oxygenation (ECMO).Methods:From January 2017 to December 2020, 60 patients from the Emergency Medicine Center of the First Affiliated Hospital of Nanjing Medical University received ECMO for life support. The baseline data of the patients were collected, the minimum value of platelets on day 1-7 of the machine was calculated, and the platelet change value and change rate were calculated. The patients were divided into the survival group and death group according to the 28-day survival status after ECMO was installed, and the receiver operating curve (ROC) was drawn based on the platelet change value and change rate to evaluate its predictive value for prognosis.Results:Among patients receiving VV-ECMO, the platelet change value and change rate on day 7 had the best prediction effect on the patient's 28-day outcome ( AUCΔPLT7=0.772, P=0.016; AUCΔPLT7%=0.764, P=0.020), when the platelet change value was 4×10 9/L as the critical value, the sensitivity was 0.857, the specificity was 0.615, and when the platelet change rate was -28.99% as the critical value, the sensitivity was 0.857, the specificity was 0.615, and when the platelet change rate was -28.99%. The sensitivity was 0.643 with a specificity of 0.846. In patients receiving VA-ECMO, the platelet change rate on day 6 predicted the best effect on the patient's 28-day outcome ( AUCΔPLT6%= 0.707, P = 0.045). When the platelet change rate was -26.19% as the critical value, the sensitivity was 0.842 and the specificity was 0.643. Conclusions:Platelet dynamic changes of platelets are correlated with the 28-day prognosis of patients receiving ECMO, and the combination of platelet change value and the critical value of change rate can better predict the poor prognosis of patients in both ECMO modes.
RESUMO
Objective:To summarize the experience and effect of extracorporeal cardiopulmonary resuscitation (ECPR) in the treatment of out-of-hospital cardiac arrest (OHCA) in adults.Methods:The data of 40 adults with OHCA-ECPR in Emergency Department of the First Affiliated Hospital of Nanjing Medical University from April 2015 to April 2022 were retrospectively analyzed. The patients were grouped by discharge survival/in-hospital death, with/without bystander resuscitation, and with/without interhospital transport. Age, sex, Charlson comorbidity index, initial rhythm, no-flow time, time from cardiac arrest to extracorporeal membrane oxygenation (ECMO) initiation (CA-Pump On time), ECMO evacuation success rate, survival rate, ECMO treatment time, time-to-death, and length of hospital stay were analyzed.Results:①Among the 40 patients with OHCA-ECPR, 9 patients (22.5%) survived upon discharge, 7 (77.8%) of whom had good neurological outcomes.②The no-flow time in the survival group was significantly shorter than that in the death group, and the proportion of shockable initial rhythm was higher.③Bystander resuscitation greatly shortened the no-flow time.④The regional OHCA-ECPR interhospital transport extended the CA-Pump On time, without affecting patients’ prognosis.Conclusions:ECPR improves the prognosis of patients with OHCA. Bystander resuscitation greatly shortens the no-flow time. ECPR is significantly effective in patients with short no-flow time and shockable initial rhythm. Regional interhospital transport ECPR is recommended to benefit more patients with OHCA.
RESUMO
Objective:To analyze whether lower anticoagulation intensity can reduce the incidence of complications in patients with extracorporeal membrane oxygenation (ECMO).Methods:Clinical data of 88 non-cardiac surgery patients who received ECMO support for more than 72 h were collected in the Extracorpical Life support Center of Jiangsu Province Hospital from March 2015 to March 2021. According to the average activated partial thromboplastin time (APTT) level on the third day of ECMO, the patients were divided into the APTT < 50 s group ( n=53) and APTT ≥50 s group ( n=35). The venovenous ECMO (VV-ECMO) subgroup was divided into the APTT <50 s group ( n=23) and APTT ≥50 s group ( n=10). The venoarterial ECMO (VA-ECMO) subgroup was divided into the APTT <50 s group ( n=30) and APTT≥50 s group ( n=25). The average daily transfusion volume of red blood cells during ECMO, the incidence of bleeding, the incidence of thrombosis and all-cause mortality were compared between the two groups. Results:There were no significant differences in the incidence of thrombosis and all-cause mortality in the APTT <50 s group compared with the APTT ≥50 s group ( P>0.05), but the incidence of bleeding and the daily transfusion volume of red blood cells were significantly decreased (7.5% vs. 35.7%; 0.50 U vs. 0.88 U) ( P < 0.05). In 33 VV-ECMO patients, the all-cause mortality, incidence of bleeding, average daily transfusion volume of red blood cells in the APTT <50 s group were lower than those in the APTT ≥50 s group, and the incidence of thrombosis was higher, but there was no statistical difference between the two groups ( P>0.05). In the 55 VA-ECMO patients, there were no significant differences in all-cause mortality, incidence of bleeding, thrombosis and average daily transfusion volume of red blood cells between the two groups ( P > 0.05). Conclusions:The lower anticoagulation intensity in patients without anticoagulation can reduce the occurrence of bleeding in ECMO patients. It is reasonable for such patients to have a lower anticoagulation intensity and studies with larger sample size need to be carried out.
RESUMO
Objective:To summarize the clinical experience of extracorporeal membrane oxygenation (ECMO) support in acute myocardial infarction (AMI) complicated by cardiogenic shock.Methods:Thirty-seven AMI patients received ECMO from March 2016 to October 2020 in Emergency Department of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Gensini score was used to evaluate the coronary lesion severity, vasoactive-inotropic score (VIS) was used to assess the usage of vasoactive-inotropic drugs, and cumulative fluid balance (CFB) was used to calculate the fluid balance status, respectively. According to the infarct-related artery, positive/negative fluid balance, and survival/death outcome, the patients were divided into the negative and positive fluid balance groups, and the survival and death groups, respectively. The relationship between Gensini score, 24-hVIS, CFB and patient outcome was analyzed.Results:Thirty AMI-ECMO patients were enrolled, 12 patients survived and 18 died with a mortality rate of 60.0%, and 80.0% of the infarct-related artery were left main and proximal left anterior descending artery. The Gensini score was 77 (52, 120), 24-h VIS 50.0 (31.1, 80.4), daily fluid volume 28.7 (26.6, 34.4) mL/(kg·d), and CBF -1.8 (-9.7, 8.0) mL/kg. The mortality and 24-h VIS of the negative fluid balance group were significantly lower than those of the positive fluid balance group, and the Gensini score, 24-h VIS and CBF of the survival group were significantly lower than those of the death group.Conclusions:LM and pLAD are the most common infarct-related arteries in AMI-ECMO patients, the Gensini score and 24-h VIS have a certain prognostic value, and early negative fluid balance may improve the survival rate.
RESUMO
Objective:To study the application of blood products in patients with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and evaluate its effect on the prognosis.Methods:A total of 83 adult patients treated with VA-ECMO in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to January 2020 were grouped by survival to explore the risk factors of 28-day mortality using binary logistic regression, and the threshold was calculated by ROC curve.Results:Platelet transfusion ( OR=2.506, 95% CI: 1.142-5.499) and non-myocarditis disease ( OR=6.881, 95% CI: 1.615-29.316) were the risk factors of 28-day mortality in adult VA-ECMO patients. The threshold of platelet transfusion was 0.427 mL/(kg·d) (sensitivity 78.4%, specificity 69.6% , AUC 0.735). Conclusions:The increased platelet transfusion is related to the poor prognosis of adult patients with VA-ECMO. Refractory myocarditis patients are better treated with VA-ECMO.
