ABSTRACT
@#Objective To analyze the perioperative safety and the short-term prognosis of non-small cell lung cancer (NSCLC) patients with preoperative arrhythmia. Methods The clinical data of NSCLC patients treated in the Department of Cardiothoracic Surgery, the First Affiliated Hospital of Chongqing Medical University from August 2020 to March 2021 were collected and observed. The patients were divided into an arrhythmia group and a control group according to whether there was arrhythmia in the 24 h ambulatory electrocardiogram examination report before operation. The incidence of intraoperative and postoperative cardiovascular events and short-term prognosis were compared between the two groups. Results A total of 466 patients were included in this study, including 338 patients in the arrhythmia group, 176 males and 162 females, with a median age of 68.0 (63.0, 72.0) years, and 128 patients in the control group, 59 males and 69 females, with a median age of 66.5 (60.0, 72.0) years. A total of 26 patients (7.7%) in the arrhythmia group were placed with temporary pacemakers before operation. There was no significant difference in the incidence of cardiovascular related events between the two groups [100 (29.6%) vs. 28 (21.9%), P=0.096]. The incidence of postoperative arrhythmia events in the arrhythmia group was higher than that in the control group [112 (33.1%) vs. 11 (8.6%), P<0.001]. The average postoperative ICU stay in the arrhythmia group was longer than that in the control group (1.1±0.7 d vs. 1.0±0.6 d, P=0.039). Conclusion Preoperative arrhythmia does not increase the risk of intraoperative cardiovascular events in NSCLC patients, but increases the incidence of postoperative arrhythmia events and prolongs ICU stay.
ABSTRACT
【Objective】 To explore the effects of massive intraoperative RBC transfusion on multiple clinical test indicators and prognosis of patients, underwent tumor surgery in order to provide evidence for rational blood transfusion and effective intervention of complications caused by massive blood transfusion in tumor patients. 【Methods】 A total of 208 patients who underwent tumor resection in our hospital from January 2019 to December 2020 and received intraoperative RBC transfusion(>10 U) were selected as the study subjects. According to the amount of blood transfusion, they were divided into group A: 10~15 U, 144 patients; Group B: >15~25 U, 48 people; Group C: >25 U, 16 people. Data of liver function, coagulation, electrolyte, platelet count and short-term prognosis were collected and compared among 3 groups before and after surgery. 【Results】 No significant difference was noticed in patient pre-operation variables including ALT (U/L), AST (U/L) and TBIL (μmol/L) among three groups recieved massive blood transfusion (P>0.05), while AST was significantly lower than that after operation (P<0.05) : 105.33±238.18 vs 113.50±185.04 vs 291.25±457.33 (P<0.05). After operation, PT (s) (14.12±2.10, 14.79±2.67 and 16.10±4.06), INR(1.25±0.20, 1.31±0.26 and 1.44±0.38) and APTT (s) (30.52±5.63, 34.57±12.80 and 34.80±10.49) extended significantly than those before operation (P<0.05), while Plt (×109/L) decreased significantly (142.32±70.07, 100.04±57.50 and 85.40±41.10)(P<0.05). After operation, serum K+ and Ca2+ decreased significantly, Na+ and Cl- increased significantly, and pH value decreased (P < 0.05). Hospital stay of group C (d) was 33.73±34.62 vs 17.74±14.83 vs 20.92±17.69 (P<0.05). The mortality rate was 2.8%(4/44) vs 6.3%(3/48) vs 18.8%(3/16)(P<0.05), and mortality rate of group C was higher than the other two groups. 【Conclusion】 Postoperative dysfunction of liver and coagulation in tumor patients may be related to intraoperative RBC transfusions and consequent acid-base imbalance and electrolyte disturbance. The more the units of RBC transfused, the more abnormal the patients' clinical indicators, also the longer the hospital stay and the worse the short-term prognosis.
ABSTRACT
@#Objective To compare and analyze the clinical effects of two kinds of frame design valves after transcatheter aortic valve replacement (TAVR). Methods We retrospectively reviewed 124 patients who underwent TAVR and were followed up for 1 year. There were 71 males and 53 females aged 75.57±6.21 years. These patients were treated with Venus-A or Edwards Sapien aortic valves. The hemodynamics and cardiac function of these two kinds of transcatheter aortic valves (THV) were evaluated by echocardiography. The 30-day mortality and 1-year clinical effect of the patients were calculated. Results Eight-one patients used Venus-A valve and 43 patients used Edwards Sapien valve. The aortic valve transaortic pressure gradient was reduced and the rate of perivalvular leakage was low (both 2.6%) in both groups, and there was no statistical difference between the two groups. The implantation rate of permanent pacemaker was 17.3% and 11.6%, respectively. The 1-month survival (94.0% and 93.0%) and 1-year survival (94.0% and 91.0%) rates were not statistically different. Conclusion The two groups of THV with different stent structures have good short-term clinical effect and low implantation rate of permanent pacemaker.
ABSTRACT
Objective To evaluate the effect of positive end-expiratory pressure (PEEP) ventilation guided by esophageal pressure (Pes) on pulmonary function after laparoscopic surgery in elderly patients.Methods Sixty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes,aged ≥ 65 yr,with body mass index of 16-28 kg/m2,scheduled for elective laparoscopic radical resection of colorectal cancer,were divided into 2 groups (n =30 each) using a random number table method:PEEP group (group P) and Pes-guided PEEP group (group PP).After induction of anesthesia,the patients were tracheally intubated and mechanically ventilated.The fresh gas flow of oxygen was set at 2 ml/L,tidal volume (VT) was 8 ml/kg,inspiratory/expiratory ratio was 1.0:(1.5-2.0),fraction of inspired oxygenwas 60％,the respiratory rate was adjusted,and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg.PEEP was set at 5 cmH2O in group P.PEEP was set according to Pes to maintain 5 mmHg ≤ transpulmonary end-expiratory pressure ≤ 10 mmHg in group PP.Forced expiratory volume first second,forced vital capacity,and maximum ventilatory volume were determined after admission to the operating room and at 1,3 and 5 days after operation.Blood samples were collected from the radial artery for blood gas analysis,PaO2 and PaCO2 were recorded,and oxygenation index (PaO2/FiO2) was calculated.Clinical Pulmonary Infection Score was assessed.The development of postoperative pulmonary complications such as pulmonary atelectasis,pneumothorax,respiratory failure,aspiration pneumonia,respiratory infections,pleural effusion and bronchial asthma was recorded.Results Compared with group P,forced expiratory volume first second,forced vital capacity,and maximum ventilatory volume,PaO2 and PaO2/FiO2 were significantly increased at 1,3 and 5 days after operation,and the Clinical Pulmonary Infection Score and incidence of pulmonary atelectasis and respiratory infections were decreased in group PP (P＜0.05).Conclusion Pes-guided PEEP can improve pulmonary function after laparoscopic surgery and decrease pulmonary complications in elderly patients.
ABSTRACT
Objective To explore the prognostic factors in Guillain Barre syndrome (GBS) in children. Methods A total of 125 children with GBS were included and grouped according to their independent walking at two and six months after discharge, and their clinical data were analyzed. Results In 125 children (74 males, 51 females) the average age was 84.49±25.32 months, and 41 were under 6 years old. 102 children had a history of prodromal infections. 32 children had cranial nerve involvement and 35 had autonomic nerve involvement. 12 children need assisted respiration. At 2 and 6 months after discharge, when compared with children who could walk independently, the rates of functional score > 3, cranial nerve involvement, and neuroelectrophysiology as denervation potential were higher in children who could not walk independently, and the differences were statistically significant (P all<0.05). Conclusions The factors that affect the short-term prognosis are denervation potential in neuroelectrophysiology, cranial nerve involvement, and functional score > 3. Early identification of uniqueness in patients and subsequent development of targeted rehabilitation training should be carried out to improve the prognosis.
ABSTRACT
Objective To observe the effects of ventilation with low tidal volume and positive end-expiratory pressure (PEEP)in different periods on the postoperative pulmonary function and short-term prognosis in aged patients undergoing abdominal surgery.Methods Sixty aged patients undergoing selective open abdominal surgery scheduled for general anesthesia,21 males and 39 fe-males,were randomized into 3 groups (n =20).Patients in group A received PEEP 1 h after the be-ginning of surgery;patients in group B received PEEP 1 h before tracheal extubation;patients in group C received PEEP intraoperatively.The secretion score in preoperative,postoperative 24 h and 72 h respectively,and the arterial blood gas analysis indexes (PaCO 2 ,PaO 2 ,A-aDO 2 ,PaO 2/FiO 2 calculation)in postoperative 1 h and 24 h were recorded.Results Compared with preoperative,in postoperative 1 h,PaCO 2 increased obviously in all groups,PaO 2 decreased in group B,A-aDO 2 in-creased in group A (P <0.05);in postoperative 24 h,PaCO 2 was significantly increased in group B and C,PaO 2/FiO 2 decreased in group B (P <0.05).Compared with postoperative 1 h,in postopera-tive 24 h,PaCO 2 and A-aDO 2 decreased obviously in group A (P <0.05).There were no differences in postoperative secretions score in between the 3 groups.Conclusion Low tidal volume combined short-range PEEP in different periods of surgery may improve postoperative pulmonary oxygenation. But they had no obvious help with postoperative pulmonary complications.
ABSTRACT
Objective To explore the short-term prognosis of tirofiban hydrochloride on the patients with acute ST-segment elevation myocardial infarction and the influence of tirofiban hydrochloride on myocardial biomarkers. Methods 334 patients with acute ST-segment elevation myocardial infarction were choosen. They were divided into two groups, 167 cases in each group. Tirofiban hydrochloride was used in the experimental group, and conventional therapy was carried out for control group. Compared the biochemical indexes, myocardial biomarkers and cardiac function of the two groups. Results The effective rate of experimental group was 165 cases (98.80%), which was higher than 150 cases (89.82%) in the control group (χ2=12.556,P<0.05). After treatment, the cardiac troponin I (cTnI) in experimental group was lower than control group (P<0.05). The levels of left ventricular end diastolic volume (LVEDV) and left ventricular endsystolic volume (LVESV) significantly decreased and the level of left ventricular ejection fraction (LVEF) increased in experimental group compared with those in control group(P<0.05).The global registry of acute coronary events (GRACE) after treatment in experimental group was lower than that in control group (P<0.05). The hyporrhea of thrombolysis in myocardial infarction (TIMI) in experimental group were 5 cases (2.99%), which was lower than 19 cases (11.38%) in control group (χ2=8.799,P<0.05).

ABSTRACT
Objective To discuss the risk factors on short-term prognosis after kidney transplantation from donors after cardiac death (DCD). Methods We retrospectively analyzed the information of donors and recipients who performed DCD donor kidney transplantation in our center between January 2011 and August 2015, including 64 donors and 95 recipients. Also, we analyzed the potential relationship among donors' clinical characteristics and the early recovery of graft function, including the incidence of delayed graft function(DGF)and the serum creatinine (SCr) on the 90th day, and infection rate after kidney transplantation.Results We found that when donors had the factors of WIT>10 min, urine volume<100 ml/h, SBP≤100 mmHg or a history of CPR, the incidence of recipients' DGF were 55.6%,73.3%,62.5%,77.8% respectively with a significant difference. Recipients would have more chance to be infected if donors have the following characteristics: male, older than 50 years, died of cerebral hemorrhage which was caused by cardiovascular diseases, WIT>30 min, treated in ICU for more than 10 days or infection. Conclusions Nowadays, DCD has become the main graft source in Chinese kidney transplantation. This research indicates that the donors' factors may affect the recovery of graft function and the incidence of infection after kidney transplantation to some extent.By evaluating rigorously and preserving quality of renal grafts carefully, DCD would become more safe and valid.
ABSTRACT
Objective To explore the function of the baseline model for end-stage liver disease (MELD) scores,MELD-Na scores and iMELD scores in short-term prognosis in the initial treatment of hepatitis B virus (HBV) related acute-on-chronic liver failure (ACLF) patients.Methods 232 HBV-related ACLF patients who received initial treatment in 302 Military Hospital of China from January 2011 to January 2013 were enrolled in this prospective clinical follow-up.The relationship between the baseline MELD scores,MELD-Na scores,iMELD scores and clinical outcomes were analyzed,and the value of these three models for short term prognosis was assessed.Results Finally the 12-week clinical follow-up was completed in 191 patients,with the completion rate of 82.33％.Eighty-five patients died,with the fatality rate of 44.50％.Compared with the survival group,in non-survival group,the baseline of MELD scores (26.65 ± 7.75 vs.21.19 ± 5.42,t=-5.720,P=0.000),MELD-Na scores (29.16 ± 11.35 vs.21.72 ± 6.33,t=-5.729,P=0.000),iMELD scores (47.19 ± 10.96 vs.38.02 ±7.01,t=-7.011,P=0.000),total bilirubin [TBil (μmol/L):374.3 ± 150.1 vs.305.5 ± 147.1,t=-3.182,P=0.002],creatinine [Cr (μmol/L):110.7 ±90.1 vs.71.1 ± 35.1,t=-4.157,P=0.000] and international normalized ratio (INR:2.3 ± 0.9 vs.2.0 ± 0.6,t=-2.754,P=0.006) were significantly increased,but the baseline of serum Na+ (mmol/L:132.8 ± 6.1 vs.136.7 ± 5.1,t=4.861,P=0.000) was significantly lowered.It was shown by Spearman correlation analysis thai the baseline MELD scores,MELD-Na scores and iMELD scores all had positive correlation with the short-term prognosis of patients (r value was 0.398,0.404,and 0.470,respectively,all P=0.000),the baseline of serum Na+ had a negative correlation with the short-term prognosis of patients (r=-0.365,P=0.000).It was shown by receiver operating characteristic curve (ROC curve) that the cut-off scores of the baseline of MELD scores,MELD-Na scores and iMELD scores were 25.07,25.43 and 43.11 respectively,and the area under ROC curve (AUC) of the baseline of MELD scores,MELD-Na scores and iMELD scores were 0.731,0.735 and 0.773,respectively.The sensitivity of the three models was 55.3％,57.7％,63.5％,and the specificity was 84.9％,84.0％,84.9％ respectively.The value of the three models had no difference in short-term prognostic prediction.According to the respective cut-off score,the three prediction models were divided into four groups,and all of them had differences in fatality rate on the whole (x2 for MELD scores was 34.740,P=0.000; x2 for MELD-Na scores was 36.861,P=0.000; x2 for iMELD scores was 50.127,P=0.000).The mortality was elevated gradually as the equation scores increased.Conclusion The baseline of MELD scores,MELD-Na scores and iMELD scores can predict well the short-term prognosis of the initial treatment in HBV-related ACLF patients,and have relatively good clinical value for guiding therapy.
ABSTRACT
Objective To discuss the correlative factors affecting the short-term prognosis in treating malignant obstructive jaundice with percutaneous transhepatie biliary drainage (PTBD) and/or percutaneous transhepatic biliary stenting (PTBS). Methods During the period of December 2008-June 2009, PTBD and/or PTBS were performed in 67 patients. The clinical date were reviewed and analyzed. According to the reduction degree of serum bilirubin and survival condition in 30 days, the patients were divided into effective group (54 cases) and ineffective group (13 cases). Single factor affecting the short-term prognosis was analyzed by using X~2 test and multi-factors were analyzed by using non-conditional logistic regression mode. Results Single variable analysis showed that time of obstruction, way of drainage, preoperative biliary infection, Child-Pugh grade, TBIL, HGB and Cr level were of statistical significance. The logistic regression analysis showed that there were obvious correlation among preoperative biliary infection, Child-grade ≥ 11 and Cr > 115 μmol/L. Conclusion The infection of the bile duct before operation, Child-grade ≥ 11 and Cr >115μmol/L carry a close relationship with the short-term prognosis of PTBD and PTBS. Therefore, an overall preoperative evaluation for malignant obstructive jaundice is of great importance.
