ABSTRACT

Objective:To explore the effect of enhanced recovery after surgery (ERAS) protocols in patients undergoing laparoscopic radical cystectomy (LRC) and intracorporeal urinary diversion (ICUD).Methods:A total of 83 patients who received LRC+ ICUD in Beijing Chaoyang Hospital from March 2014 to September 2020, were divided into 2 groups based on different perioperative management, including 29 ERAS cases and 54 conventional recovery after surgery (CRAS) cases. The ERAS group included 26 males and 3 females , with an average age of (62.07 ± 9.26) years. There were 26 patients with ASA class Ⅰ-Ⅱ, 3 patients with ASA class Ⅲ, 4 patients received neoadjuvant chemotherapy, and 7 patients had a history of abdominal surgery in ERAS group. The CRAS group included 44 males and 10 females , with an average age of (61.59 ± 10.16) years. There were 50 patients with ASA class Ⅰ-Ⅱ, 4 patients with ASA class Ⅲ, 9 patients received neoadjuvant chemotherapy, and 10 patients had a history of abdominal surgery in CRAS group. There were no statistically significant differences in the baseline characteristics between the two groups. The patients in both groups underwent LRC+ ICUD procedures. The perioperative results and complications between the two groups were compared.Results:In the ERAS group, there were 20 patients who underwent Bricker ileal conduit surgery and 9 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 3, 3, 7, 7, 5 and 4 cases in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 23, 2, 3 and 1 patient with pathological stage N 0, N 1, N 2 and N 3, respectively. Pathological diagnosis included 3 cases of low-grade urothelial carcinoma, 24 cases of high-grade urothelial carcinoma, and 2 cases of other histological subtypes. In the CRAS group, there were 31 patients who underwent Bricker ileal conduit surgery and 23 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 5, 3, 12, 9, 15 and 10 patients in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 35, 6, 7 and 6 patients with pathological stage N 0, N 1, N 2, and N 3, respectively. Pathological diagnoses included 6 cases of low-grade urothelial carcinoma, 45 cases of high-grade urothelial carcinoma, and 3 cases of other histological subtypes. There were no statistically significant differences ( P>0.05) in surgical methods, pathological staging, or pathological types between the ERAS and CRAS groups. ERAS group presented less albumin loss [(25.73±8.63)% vs. (32.63±9.05)%, P=0.001], shorter hospital stay [9(7, 13)d vs. 12(9, 16)d, P=0.006], less 30-day overall complications [55.2% (16/29) vs. 83.3% (45/54), P=0.009]. In multivariable analysis, maximum albumin loss≥20% was independently associated with 30-day minor complications ( P=0.049), and maximum albumin loss ≥25% was independently associated with hospital of stay≥10 days ( P=0.038), respectively. Conclusions:For patients who received LRC+ ICUD, ERAS was associated with reduced perioperative albumin loss, shorter length of stay, less 30-day complications, accelerated recovery time, improved clinical outcome and less albumin injection.

ABSTRACT

Objective:To construct the prediction model for the prolonged length of postoperative hospital stay in the patients undergoing thoracoscopic lobectomy.Methods:The patients of both sexes, aged ≥18 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, who received elective thoracoscopic lobectomy with general anesthesia from March 2016 to February 2019 in our hospital, were selected, their clinical data were collected, and the patients were pathologically diagnosed with non-small-cell lung cancer after operation.Basic information (sex, age, smoking history), previous history (dyslipidemia, hypertension, diabetes, cardiovascular and cerebrovascular diseases, peripheral vascular diseases, chronic obstructive pulmonary diseases), allergy history, other tumor history, surgical resection site, anesthetic factors (intraoperative use of non-steroidal anti-inflammatory drugs and glucocorticoids, duration of anesthesia, intraoperative epidural anesthesia + postoperative epidural analgesia) and postoperative complications (pleural effusion, pneumothorax, atelectasis) was collected.The patients were divided into 2 groups according to whether the length of postoperative hospital stay was prolonged: normal group (≤ 7 days) and prolonged group (>7 days).Logistic regression analysis was used to identify the predictors for prolonged length of postoperative hospital stay.The regression model for prediction of prolonged length of postoperative hospital stay was constructed based on the TensorFlow deep learning framework, and the efficacy of prediction was evaluated.A deep neural network was further established based on the TensorFlow framework to construct a classification prediction model for prolonged length of postoperative hospital stay, and the efficacy of prediction was assessed, further comparing it with the prediction model constructed by the traditional machine learning method.Results:A total of 428 patients were finally enrolled in the study.The results of multivariate logistic regression analysis showed that age and anesthesia duration were the risk factors for the prolonged length of postoperative hospital stay, and female, other tumor history and resection of right middle lobe were the protective factors ( P<0.05).The performance of the regression model proved ineffective, getting 2.16 mean absolute error and 11.05 mean square error on the training set, 2.14 mean absolute error and 11.73 mean square error on the test set.The classification model achieved better score with accuracy 75.58%, F1-measure 0.553 and area under the receiver operating characteristic curve 0.702 on the test set, however, it showed no better performance than that of 4 other prediction models established by 4 traditional machine learning methods, specifically Logistic Regression, Random Forest, Gradient Boosting and Support Vector Machine. Conclusions:Sex, age, surgical resection site, other tumor history and duration of anesthesia can serve as the predictors, and a classification prediction model for prolonged length of postoperative hospital stay is constructed based on a deep neural network in the patients undergoing thoracoscopic lobectomy.

ABSTRACT

Objective:To compare the sedative efficacy of bispectral index (BIS)-guided dexmedetomidine and propofol in the elderly patients undergoing percutaneous kyphoplasty (PKP).Methods:Sixty elderly patients of both sexes, aged 70-90 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, scheduled for elective PKP with local infiltration anesthesia, were divided into 2 groups ( n=30 each) using a random number table method: dexmedetomidine group (group D) and propofol group (group P). In group D, dexmedetomidine was infused for 10 min in a loading dose of 0.5 μg/kg followed by an infusion of 0.2-0.7 μg·kg -1·h -1 for maintanence.In group P, propofol was injected in a loading dose of 1.0 mg/kg followed by an infusion of 1-2 mg·kg -1·h -1 for maintanence.Local infiltration anesthesia was performed with 1% lidocaine 20-30 ml after disinfection and layering.The target BIS value was mainatined at 80-90.On admission to the operating room (T 0), at puncture (T 1), after balloon dilation (T 2), at the end of bone cement injection (T 3), and at the end of surgery (T 4), Ramsay sedation score was recorded, and the occurrence of adverse reactions such as hypotension, respiratory depression, bradycardia, nausea and vomiting was recorded during operation. Results:Compared with group P, the Ramsay score was significantly decreased, the incidence of bradycardia was increased, and the incidence of respiratory depression was decreased at T 1-4( P<0.05), and no significant change was found in hypotension and nausea and vomiting in group D ( P>0.05). Conclusion:Dexmedetomidine provides better sedative efficacy than propofol, but the occurrence of bradycardia should be prevented in the elderly patients undergoing PKP.

ABSTRACT

Objective:To identify the risk factors for mortality after laparotomy for hemorrhage in the patients with bleeding after liver transplantation.Methods:The patients who underwent re-laparotomy for hemorrhage after liver transplantation, aged>18 yr, from June 2005 to June 2013, were selected.The preoperative clinical characteristics of patients, time of liver transplantation, mode of operation, intraoperative massive hemorrhage, intraoperative use of vasoactive drugs, atropine, lidocaine and immunosuppressive agents, and postoperative tracheotomy and renal failure were collected.Patients were divided into survival group (group S) and death group (group D) according to the survival outcome at 3 months after surgery.Factors of which P values were less than 0.05 would enter the multiple logistic regression analysis to stratify the risk factors for mortality of patients with bleeding after liver transplantation. Results:A total of 128 patients were included in this study , with 117 cases in group S and 11 cases in group D. Postoperative renal failure was the independent risk factor for mortality of patients with bleeding after liver transplantation, and OR value (95% confidence interval) was 11.307 (1.992-64.188) ( P<0.05). The area under the curve of postoperative renal failure (95% confidence interval) was 0.849 (0.712-0.986), and the sensitivity and specificity were 81.8% and 12.0%, respectively. Conclusion:Postoperative renal failure is an independent risk factor for mortality after laparotomy for hemorrhage in the patients with bleeding after liver transplantation.

ABSTRACT

Objective To investigate the effect of low platelet (PLT) count on the early fatality rate of liver transplant recipients without intraoperative PLT transfusion. Methods Clinical data of 180 recipients undergoing orthotopic liver transplantation were retrospectively analyzed. The critical value of PLT count on postoperative 7 d to predict the early postoperative fatality rate was evaluated by the receiver operating characteristic(ROC) curve. All recipients were divided into the low PLT count group and control group according to the critical value. Relevant clinical data including perioperative PLT count, preoperative general conditions and intraoperative conditions of the recipients were included. The independent risk factors of the early fatality rate of liver transplant recipients were analyzed by Logistic regression analysis. The early prognosis of the recipients between two groups was observed and compared by the postoperative length of intensive care unit (ICU) stay, postoperative length of hospital stay, early allograft dysfunction and fatality rate on postoperative 30 d. Results The PLT count < 32×109/L on 7 d after liver transplantation was an independent risk factor of the fatality rate on postoperative 30 d (P < 0.05). The postoperative length of ICU stay of the recipients in the low PLT count group was 9 (5, 14) d, significantly longer than 5 (3, 6) d in the control group (P < 0.05). In the low PLT count group, the early allograft dysfunction rate was 55.0%, significantly higher than 20.6% in the control group (P < 0.05). In the low PLT count group, the fatality rate on postoperative 30 d was 40.0%, significantly higher than 2.5% in the control group (P < 0.05). The length of hospital stay did not significantly differ between two groups (P > 0.05). Conclusions The PLT count < 32×109/L on postoperative 7 d is an independent risk factor for the fatality rate on postoperative 30 d of liver transplant recipients. It can prompt the early allograft dysfunction and contribute to predict the early clinical prognosis of liver transplant recipients.

ABSTRACT

Objective To compare the accuracy of three acute kidney injury (AKI) criteria of RIFLE, Acute Kidney Injury Network (AKIN) and Kidney Disease: Improving Global Outcomes (KDIGO) in predicting the early (30 d) postoperative death of liver transplant recipients. Methods Clinical data of 173 liver transplant recipients were retrospectively analyzed. The incidence of postoperative AKI was calculated according to the three criteria of RIFLE, AKIN and KDIGO. The all-cause fatality rate and cause of death at postoperative 30 d were analyzed. The risk factors of death within 30 d after operation were analyzed by binary Logistic regression. The prediction accuracy of three criteria for death within 30 d after operation was compared by the receiver operating characteristic (ROC) curve. Results According to the RIFLE, AKIN and KDIGO criteria, the incidences of postoperative AKI were 48.0%, 51.4% and 53.8%, respectively. Thirteen patients died within 30 d after operation and the fatality rate was 7.5%. RIFLE, AKIN and KDIGO stages were the independent risk factors for death within 30 d after operation (all P < 0.05). The area under the curve (AUC) of RIFLE, AKIN and KDIGO stages to predict death within 30 d after liver transplantation were 0.828, 0.766 and 0.844, respectively. There was a statistically significant difference between AKIN and KDIGO (P < 0.05). Conclusions KDIGO criterion is better for predicting early death after liver transplantation. However, as a tool, the comparative selection among these three criteria still needs the evidence support from a large multicenter sample.

ABSTRACT

Objective To compare the accuracy of lactate concentration and model for end-stage liver disease (MELD) to predict early mortality after liver transplantation, and to provide a convenient and timely predictive tool for clinical work. Methods A total of 121 patients who underwent Allograft liver transplantation in 2017 in our hospital, 92 males and 29 females, aged 25-78 years old, ASA physical status Ⅲ or Ⅳ, were selected to the retrospective study. Patients were divided into survival group and non-survival group, according whether survived within 30 days after the surgery. The preoperative and postoperative lactate concentrations were gotten and the preoperative and postoperative MELD scores were calculated. The preoperative lactate concentrations, postoperative lactate concentrations, preoperative MELD scores and postoperative MELD scores were compared between survival group and non-survival group, respectively. The predictive accuracy about early mortality (30 days) of lactate concentration and MELD score were compared at preoperation and postoperation through receiver operating characteristic, respectively. Results There were 109 patients (90.0%) survived and 12 patients (10.0%) non-survived within 30 days after the surgery. Compared with survival group, the preoperative lactate concentrations, postoperative lactate concentrations, preoperative MELD scores and postoperative MELD scores in the non-survival group were significantly increased (P < 0.05). According to the ROC analysis, the area under the curve (AUC) of ROC of preoperative lactate concentration was 0.78 (95% CI 0.62-0.93) with a cutoff value of 2.43 mmol/L, the AUC of preoperative MELD score was 0.70 (95% CI 0.53-0.87) with a cutoff value of 24.50 scores. There was not statistically significant between the AUC of preoperative MELD score and lactate concentration. The AUC of postoperative lactate concentration was 0.85 (95% CI 0.70-0.99) with a cutoff value of 9.57 mmol/L, the AUC of postoperative MELD score was 0.74 (95% CI 0.61-0.88) with a cutoff value of 25.42 scores. The AUC of postoperative lactate concentration was statistically higher than that of MELD score (P < 005). Conclusion The predictive capability of lactate concentration, especially that of postoperative lactate concentrations, was better than the predictive capability of MELD score.

ABSTRACT

Objective To explore the perioperative outcomes and safety of enhanced recovery after surgery (ERAS) in laparoscopic radical cystectomy (LRC).Methods We retrospectively evaluated outcome of 10 LRC patients on ERAS protocol from May 2017 to October 2017,and 39 LRC patients on conventional recovery after surgery(CRAS) protocol from July 2015 to November 2016.There were (60.9 ±11.4) years and (63.7 ± 12.1) years in ERAS group and CRAS group respectively(P =0.514);(25.5 ±2.7) kg/m2 and (24.4 ± 3.6) kg/m2 with body mass index (P =0.375).Both of the median of charlson comorbidity index (P =0.931) and American Society of Anesthesiologists score (P =0.254) were 2 There was no statistical significance between the two groups for type of urinary diversion and preoperative laboratory studies (P > 0.05).Patients' perioperative outcomes,early (30-day) complications and postoperative readmission rate were compared.Results The ERAS group had less intraoperative crystalloid infusion [(950.0 ± 474.3) ml vs.(1 797.4 ± 448.1) ml,P < 0.001],faster removed gastric tube (0 d vs.4 d,P <0.001),and shorter passing flatus time [(1.6 ± 0.8) d vs.(2.9 ± 1.4) d,P =0.006] than the CRAS group;however,no difference was found in terms of intraoperative colliod infusion [(1 110.0 ± 331.5)ml vs.(1 117.9 ± 397.9) ml,P =0.954].No patients from either group required conversion to open surgery.There was no significant difference between the two groups for operative time (P =0.311),estimated blood loss (P =0.073),drain days (P =0.681),postoperative hospital stay (P =0.509),overall blood transfusion (P =1.000),intensive care unit stay (P =1.000) and tumor characteristics (pathological stage,histology,nodes removed,positive nodes,lymph node-positive patients,positive surgical margins).The 30-day postoperative complications were documented in 5 (50%)and 23 (59%)patients in groups ERAS and CRAS (P =0.878),respectively.And the most common complication were minor complications (Clavien-Dindo grade 1 and 2) in both groups (100.0% vs.86.9%,P =0.729).The 30-day readmission rate was 20.0% (2 patients) in ERAS group and 10.3% (4 patients) in CRAS group with no statistical significance(P =0.588).Conclusions Our ERAS protocol expedited bowel function recovery after RC and urinary diversion without increasing in 30-day complications compared with CRAS.The key of implement ERAS pathway is to explore and develop their own protocol conformed to their medical treatment enviroment.

ABSTRACT

Objective To observe the effect of ultrasound-guided single erector spinae plane (ESP ) block combined with patient-controlled intravenous analgesia (PCIA ) on postoperative analgesia in patients undergoing lobectomy performed via video-assisted thoracoscope. Methods Forty patients (20 males and 20 females,ASA physical status Ⅰ or Ⅱ),scheduled for e-lective video-assisted thoracoscopic lobectomy,were randomly assigned into two groups,ESP block combined with PCIA group (group EP)and PCIA only group (group P).ESP block was given to pa-tients in group EP before operation,and its effect was evaluated by testing the area of block.VAS scores were recorded at 1,6,18,24 and 48 h after operation.The frequency for compress PCIA,the volume of analgesic drugs,the consumption of flurbiprofen axetil and the side-effects were recorded as well.Results ESP block was accomplished in group EP with sensory loss from T2-T8 or T3-T7 over the entire posterolateral aspect of the hemithorax.And there were no puncture-related complications. The VAS scores both at rest and coughing in group EP were lower than those in group P (P <0.05). The compress PCA numbers,the volume of analgesic drugs and the consumption of flurbiprofen axetil were significantly less in group EP than those in group P (P <0.05).Only nausea and vomiting were observed as postoperative side effects,and there were no significant differences between the two groups.Conclusion Ultrasound-guided single erector spinae plane block combined with PCIA is a sa-fer and more effective method for the analgesia of thoracic operation than PCIA only.

ABSTRACT

Objective To evaluate the effect of pretreatment with botulinum toxin A injected intrath?ecally or locally at the incision site on the neurokinin?1 ( NK?1) receptor internalization in the spinal dorsal horn in a rat model of incisional pain. Methods Male Sprague?Dawley rats, weighing 280-300 g, aged 6-8 weeks, were used in the study. The experiment was performed in two parts. ExperimentⅠ Twenty?seven rats with no sign of nerve injury at day 7 after successful catheterization were selected and divided into 3 groups (n=9 each) using a random number table: control group (C1 group), incisional pain group (IP1 group) and intrathecal botulinum toxin A group (BoNT∕A1 group). At 24 h before operation, botulinum tox?in A 0.5 U ( in 10μl of normal saline) was injected intrathecally in group BoNT∕A1, and normal saline 10μl was injected intrathecally in group IP1. ExperimentⅡ Twenty?seven rats were selected and divided into 3 groups (n=9 each) using a random number table: control group (group C2), incisional pain group (IP2 group) and locally injected botulinum toxin A at the incision site group (BoNT∕A2 group). At 24 h before op?eration, botulinum toxin A 2 U ( in 0.4 ml of normal saline) was injected subcutaneously at the incision site and into the plantar surface, and normal saline 0.4 ml was injected subcutaneously at the incision site and into the plantar surface in group IP2. Six rats in each group were selected, and the cumulative pain score (CPS) was recorded, and the mechanical paw withdrawal threshold ( MWT) in the right hindpaw was measured be?fore administration, before operation, and at 3 h and 1, 3, 5 and 7 days after operation. At 3 h after opera?tion, 3 rats in each group were selected and sacrificed, and the lumbar segment ( L4,5 ) of the spinal cord was removed for determination of the expression of NK?1 receptors in the spinal dorsal horn by immunofluores?cence. Results ExperimentⅠ Compared with group C1, the CPS was significantly increased at 3 h and 1, 3, 5 and 7 days after operation, the MWT was significantly decreased at 3 h and 1 and 3 days after opera?tion, and the expression of NK?1 receptors in the spinal dorsal horn was significantly up?regulated in group IP1, and the CPS was significantly increased at 3 h and 1, 3 and 5 days after operation, the MWT was sig?nificantly decreased at 3 h after operation ( P0.05). Compared with group IP1, the CPS was significantly decreased, and the MWT was significantly increased at 3 h and 1, 3, and 5 days after oper?ation, and the expression of NK?1 receptors in the spinal dorsal horn was significantly down?regulated in group BoNT∕A1 (P0.05) . Compared with group IP2, the CPS was significantly decreased at 3 h and 1, 3, and 5 days after operation, the MWT was signifi?cantly increased at 3 h and 1 and 3 days after operation, and the expression of NK?1 receptors in the spinal dorsal horn was significantly down?regulated in group BoNT∕A2 (P<0.05). Conclusion Pretreatment with botulinum toxin A injected intrathecally or locally at the incision site can inhibit the internalization of NK?1 re?ceptors in the spinal dorsal horn in a rat model of incisional pain.

ABSTRACT

Objective To evaluate the feasibility of using stroke volume variation (SVV) as the left ventricular preload to draw the cardiac function curve.Methods Twenty-seven patients of both sexes,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status Ⅱ (New York Heart Association Ⅱ),with abnormal cardiac function,scheduled for elective offpany coronary artery byp grafting,were enrolled in this study.Twenty-five patients,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status Ⅰ (New York Heart Association Ⅰ),with normal cardiac function,scheduled for elective non-cardiac surgery,were also enrolled in this study.SVV and SV were monitored by using a FloTrac/VigileoTM system.The patients were in the supine position from the end of anesthesia induction to the beginning of surgery.After the hemodynamics was kept stable for 5 min,SVV and SV were recorded.6% hydroxyethyl starch 130/0.4 500 ml was intravenously infused over 20 min.SVV and SV were recorded after volume expansion.Spearman rank-order correlation was used to analyze the relationship between SVV and SV.The quadratic regression analysis was used to draw the SVV-SV curve,and the SVV-SV curve was compared with the Frank-Starling curve.Results Compared with the value before volume expansion,SVV and HR were significantly decreased,and SV was increased after volume expansion in the patients with normal cardiac function,and SVV was decreased after volume expansion in the patients with abnormal cardiac function (P<0.01).SVV was negatively correlated with SV in the patients with normal cardiac function,and r=-0.467 (P<0.05).SVV was negatively correlated with SV in the patients with abnormal cardiac function,and r=-0.378 (P<0.05).The mirror symmetry was found between the SVV-SV curve in the patients with normal cardiac function and the normal Frank-Starling curve,and the general trend was close.The symmetry was not detected between the SVV-SV curve in the patients with abnormal cardiac function and the Frank-Starling curve in the patients with decreased myocardial contractility,and the general trend was not close.Conclusion For the patients with normal cardiac function,SVV can be used as the left ventricular preload to draw the cardiac function curve.

ABSTRACT

Objective To evaluate the effects of lidocaine in combination with sevoflurane on myocardial protection in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods One hundred ASA physical status Ⅱ or Ⅲ and NYHA class Ⅰ or Ⅱ patients of both sexes,aged 45-70 yr,weighing 63-82 kg,scheduled for elective OPCABG,were randomly assigned into 4 groups (n=25 each):control group (group C),lidocaine group (group L),sevoflurane group (group S),sevoflurane combined with lidocaine group (group SL).Tracheal intubation was performed after induction of anesthesia.Anesthesia was maintained with iv infusion of propofol and intermittent iv boluses of sufentanil and pipecuronium.Bispectral index value was maintained at 45-55.Lidocaine 1.5 mg/kg was injected after intubation,followed by infusion at 2 mg/min until the end of surgery in L and SL groups.Sevoflurane was inhaled with end-tidal concentration of 2.2%-2.5% starting from the end of intubation until the end of operation in S and SL groups.Before induction of anesthesia,at skin incision,immediately after transsection of internal mammary artery,after completion of anastomosis of the proximal aortovein and distal coronary artery,at the end of operation and at 24 h during operation,venous blood samples were obtained to detect the levels of plasma creatine kinase (CK),creatine kinase isoenzyme-MB (CK-MB) and cardiac troponin Ⅰ (cTnI).Lidocaine-related side effects such as arrhythmia,bradycardia or cardiac arrest were recorded during operation and within 24 h after operation.Results Compared with group C,the plasma CK,CK-MB and cTnI levels were decreased in the S,L and SL groups.The plasma CK-MB and cTnI levels were significantly lower in SL group than in L group.The plasma CK,CK-MB and cTnI levels were significantly lower in SL group than in S group.In L and SL groups,no patient developed lidocainerelated side effects.Conclusion Lidocaine 1.5 mg/kg injected intravenously after intubation,followed by infusion at 2 mg/min in combination with sevoflurane end-tidal concentration about 2.2% ~2.5% provides myocardial protection in patients undergoing OPCABG,the efficacy is stronger than that of either alone.
