Objective To investigate the changes of renal medulla aquaporin 2 expression and morphological changes of epithelia of collecting tube after bile duct recanalizaiton operation. Methods Thirty rats were divided into two groups randomly. Common bile duct ligation was performed on 20 experimental rats with silicon tubes 2 mm in extre-diameter, and sham operation on the other 10 rats. Seven days later, bile duct recanalizaiton was performed on obstructive jaundice group and sham operation on contrast group. Experimental rats were divided into two subgroups randomly. Half of them were killed immediately and the others would be killed 24 hours later. Serum of each rat was collected to detect hepatic function and renal function. Renal medulla was fixed for microscopic examination and was kept in the -80 ℃ refrigerator for aquaporin 2 expression measurement by Western blot technique. Results All of the animals accomplished the experiment smoothly. Golden ascites were found in the rats of obstructive jaundice group. Twenty-four hours after recanalization, serum bilirubin levels decreased 〔(45.95±8.39) μmol/L〕, P＜0.01, and there was no significant change in blood urine and creatine level. Compared with sham operation group (21 966.20±1 544.70), expression of aquaporin 2 decreased significantly after common bile duct ligation in obstructive jaundice group (15 665.30±1 181.85), P＜0.01. After recanalizaion, the expression of aquaporin 2 in obstructive jaundice group increased (19 490.80±4 239.32), P＜0.01. Conclusion Common bile duct obstruction would lead to epithelium injury of renal collecting tube, and down regulate the aquaporin 2 expression.
ObjectiveTo explore the effect of perioperative nutritional management on patients with spinal cord injury under the enhanced recovery after surgery (ERAS) theory.MethodsA total of 82 patients with spinal cord injury admitted to a tertiay hospital in Shanghai between August 2018 and May 2020 were selected by convenience sampling method. They were randomly divided into intervention group and control group, with 41 cases in each group. The patients in the control group received conventional orthopaedics elective surgery nutritional management, while the patients in the intervention group adopted perioperative nutritional management based on ERAS concept, including establishing a multidisciplinary nutritional management team, conducting admission and regular nutritional screenings, and then developing targeted nutritional interventions based on the screening results. Biochemical indexes of nutritional assessment, electrolyte indexes, nutrition-related complications and general inpatient indexes were observed and compared between the two groups.ResultsThere were statistically significant differences in albumin, prealbumin, total protein, hemoglobin, potassium, sodium, and chlorine between the two groups on the first day after surgery and one day before discharge (P<0.05). The incidences of hypoglycemia (2.4% vs. 19.5%) and total complications (19.5% vs. 61.0%) in the intervention group were lower than those in the control group, and the differences were statistically significant (P<0.05). The total hospital stay [(10.48±2.61) vs. (12.09±2.74) d], postoperative hospital stay [(5.57±2.35) vs. (7.55±3.01) d], and hospital expenses [(11.21±4.42)×104 vs. (14.73±5.51)×104 yuan] in the intervention group were less than those in the control group (P<0.01).ConclusionPerioperative nutritional management under the ERAS theory can effectively improve the nutritional status of patients with spinal cord injury, maintain electrolyte balance, reduce the incidence of complications, shorten the length of hospitalization, reduce the cost of hospitalization, and promote postoperative rehabilitation of patients.
ObjectiveTo explore the risk factors for surgical patients associated with postoperative nosocomial infection through monitoring the infection conditions of the patients, in order to provide a scientific basis for the development of hospital infection control measures in a second-grade class-A hospital in Chengdu City. MethodsWe conducted the survey with cluster sampling as the sampling method and the uniform questionnaire in the departments of orthopedic, neural and thoracic surgery from July 2011 to June 2012. The main parameters we observed were the patients'general and surgical conditions, antibiotics usage and hospital infection situation. Data were analyzed using the National Nosocomial Infection Surveillance Network software and chi-square test of single factors. ResultsIn this survey, we monitored 50 cases of postoperative hospital infection. The infection rate was 7.73% and the highest infection rate was in the Neurosurgery Department. The main site of infection was lower respiratory tract, followed by surgical site. The different usage time of antimicrobial drug in perioperative period resulted in different infection rates, and the difference was statistically significant (χ2=601.50, P<0.005). The rate of adjusted postoperative hospital infection was higher than pre-adjusted rate except that of the neurosurgery doctor 4. The risk factors associated with hospital postoperative infection in our hospital were:patients'conditions including underlying disease, emergency surgery, type of anesthesia, operative duration, hospital stay and postoperative drainage. Most of the hospital infection cases were caused by bacteria of the gram-negative bacilli, and the major pathogens were Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii in our hospital. ConclusionThe hospital should particularly strengthen the prevention and control of hospital infection in patients after neurosurgical operations. For patients with basic diseases, we should actively improve the patients'physical conditions before operation and control the primary lesion. Targeted control measures should be taken for different factors related to surgery. Reasonable selection of antimicrobial agents should be based on the epidemic strains in our hospital.
ObjectiveTo explore clinical efficacy of Frey procedures for chronic pancreatitis. MethodsThirty two patients with chronic pancreatitis who underwent Frey procedures in our hospital from June 2000 to October 2009 were analyzed retrospectively. The rate of perioperative complications, pain relief, and especially endocrine and exocrine function of pancreas in longterm followup (mean 43 months) were analyzed. ResultsNo death occurred in all patients. Fat liquefaction of wound was found in two patients and pancreatic fistula was found in one patient, who was cured by conventional treatment. So the rate of perioperative complications was 9.4%(3/32). After Frey procedures, pain disappeared completely in sixteen patients (50.0%), pain relieved in fourteen patients (43.8%) and two cases were ineffective. Therefore, the rate of pain relief in longterm follow-up was 93.8%. The hospitalization was (11±2) d. After surgical treatment the illness of five patients with diabetes mellitus did not aggravate while new onset of diabetes mellitus was observed in three cases. For three cases who suffered from indigestion and steatorrhea, symptomatic relief was found in one patient treated by oral administration of pancreatin and inefficacy was observed in two cases. But four patients with new steatorrhea were found after operation. ConclusionUnder the strict surgical indications, Frey procedure is a safe and effective surgical method for the treatment of chronic pancreatitis.
ObjectivesTo systematically review the efficacy and safety of fast track surgery in perioperative patients with adrenalectomy.MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy and safety of fast track surgery in perioperative patients with adrenalectomy from inception to January 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 11 RCTs involving 1 034 patients were included. The results of meta-analysis showed that: fast track surgery in perioperative patients with adrenalectomy could shorten first exhaust time (MD=−17.16, 95%CI −21.86 to −12.46, P<0.000 01), postoperative catheter indwelling time (MD=−43.44, 95%CI −46.65 to −40.23, P<0.000 01) and drainage tube indwelling time (MD=−39.91, 95%CI −57.58 to −22.23, P<0.000 01), and reduce the incidence of complications after adrenalectomy (OR=0.26, 95%CI 0.1 to 0.39, P<0.000 01). There were no statistically differences in operation time (MD=−1.18, 95%CI −3.22 to 0.86, P=0.26) and blood loss (MD=0.25, 95%CI −2.84 to 3.34, P=0.88) between two groups.ConclusionsCurrent evidence shows that, compared with the conventional rehabilitation group, fast track surgery can promote postoperative recovery of patients with adrenalectomy more safely and effectively, which has clinical promotion value. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Objective To explore the application effect of process optimization in perioperative venous access management. Methods A total of 205 general surgery patients in the Operating Room of Cheng Du Shang Jin Nan Fu Hospital, West China Hospital of Sichuan University from April to May 2018 were selected as the control group, and 205 general surgery patients from June to August 2018 were selected as the observation group. The traditional management process was used in the control group, and the process optimization management was performed in the observation group. The establishment of venous access and related complications between the two groups of patients, as well as the satisfaction of patients and staff before and after the process optimization were compared. Results There was no significant difference in gender, age, education level, operation type, anesthesia method, operation duration, or intraoperative intravenous infusion channels between the two groups of patients (P>0.05). There was no statistically significant difference in gender, age, educational background, job title, job nature, or working years of the staff participating in the satisfaction survey before and after the process optimization (P>0.05). The rate of repetitive venous puncture (15.61% vs. 58.05%) and the idelness ratio of the intraoperative indwelling needle approach (10.73% vs. 52.20%) in the observation group were lower than those of the control group, and the differences were statistically significant (P<0.05). There was no statistically significant difference in the incidence of tube blockage, detubation, or phlebitis/exudation between the two groups (P>0.05). After process optimization, patient satisfaction (22.91±3.43 vs. 17.44±4.90) and staff satisfaction (28.17±2.56 vs. 20.65±3.71) were higher than before optimization, and the differences were statistically significant (P<0.05). Conclusions The process optimization of venous access management for perioperative patients can effectively reduce the rate of venous repeated venipuncture and the idelness ratio of the intraoperative indwelling needle approach, reduce invasive operations on patients, reduce the ineffective work of nurses, avoid the waste of medical resources such as manpower and materials, and improve the satisfaction of patients and staff. It is worthy of promotion and application.
Objective To review the value of imaging assessment for perioperative period of liver transplantation. Methods The related literatures in recent years were reviewed, and the applications of various kinds of radiological techniques in perioperative period of liver transplantation and radiological strategies of major complications after liver transplantation were summarized. Results Transplantation has become an effective option for treatment of patients with irreversible severe liver dysfunction. Radiological assessment supplies prompt and accurate information for clinic to increase the success rate and reduce the complications. So it plays an irreplaceable role. Conclusions Radiology assessment is important for screening donors and recipients before liver transplantation， following up and monitoring the complications. The doctor of imaging department could grasp the different imaging appearance in perioperative period of liver transplantation.
ObjectiveTo summarize the experience of intra-aortic balloon pump (IABP) application on coronary artery bypass grafting（CABG）during perioperative period. MethodsWe retrospectively analyzed the data of 82 patients undergoing simple CABG operation in Wuhan Asia Heart Hospital between January 2011 and December 2013. There were 50 male and 32 female patients at age of 49-75 (63.6±11.5) years. The patients were divided into three groups including a group A (12 patients, preoperative-placed IABP), a group B(39 patients , postoperative active placed IABP), and a group C (31 patients, postoperative passive placed IABP). The clinical effects of the three groups were compared. ResultsThere were significantly statistic differences in sequential organ failure assessment (SOFA) score after postoperative 48 hours, ventilator supporting time, IABP supporting time, catecholamine drug usage time, infection incidence, incidence of ventricular arrhythmia, ICU retention time, postoperative hospital stay, CBP usage rate, and postoperative mortality (P<0.05) among the three groups with worse effect in the group C. ConclusionTaking IABP support during CABG perioperative period is an effective treatment. Preventively preoperative and actively postoperative placing IABP can improve the treatment effects significantly. Therefore, patients should apply CABG as soon as possible without hesitation when IABP indications occur.
Objective To explore the clinical efficacy of nursing measures based on the concept of enhanced recovery after surgery (ERAS) for patients undergoing day surgery of inguinal hernia repair. Methods A total of 120 patients scheduled for day surgery of inguinal hernia repair between January and June 2015 were randomized into ERAS group (n=60) and control group (n=60). Patients in the ERAS group received nursing optimized by the idea of ERAS during the perioperative period, while those in the control group received traditional routine nursing intervention. Postoperative visual analogue scale (VAS) scores, adverse responses, early ambulation, influence of pain on patients’ sleep, satisfaction of the patients and prolonged hospital stay rate were analyzed and compared between the two groups. Results VAS scores during hours 0-2, 2-4, 4-8, and 8-12 in the ERAS group were significantly lower than those in the control group (P < 0.05). Between hour 12 and 24, the VAS sco res were not significantly different between the two groups of patients (P > 0.05). Early postoperative ambulation, influence of pain on the sleep, and patients’ satisfaction on pain control and nursing care in the ERAS group were all significantly better than those in the control group (P <0.05). Conclusion Based on the concept of ERAS nursing intervention model, we can effectively reduce postoperative complications after inguinal hernia repair, accelerate patients’ postoperative rehabilitation, and increase patients’ satisfaction.
Objective To investigate the status of nutrition, nutritional support, and postoperative nutrition-related complications in patients with spinal deformity during orthopedic perioperative period. Methods From February to August 2021, patients who underwent spinal orthopedic surgery for spinal deformity in Peking University Third Hospital were collected. A survey was conducted using self-designed questionnaire, including patient’s general information (gender, age, and type of spinal deformity), nutrition-related information (risks of malnutrition, forms of nutritional support), and postoperative nutrition-related complications. Results A total of 39 patients with spinal deformity were enrolled, and 46.2% (18 cases) were at risk of malnutrition. There were a total of 174 times of nutritional support, and 96.0% (167 times) were parenteral nutrition. The patients’ energy intake from nutritional support accounted for 34.41% of the daily goal energy intake averagely. At admission, one day after operation, and at discharge, the prealbumin was (215.51±34.69), (172.85±31.85), and (163.67±29.15) mg/L, respectively, and the hemoglobin was (138.08±15.67), (119.92±18.01), and (117.69±14.76) g/L, respectively, which were significantly lower one day after operation and at discharge than those at admission (P<0.01). The incidence of postoperative nutrition-related complications during hospitalization was 5.1% (2/39). Conclusions Patients undergoing spinal deformity orthopedics are at high risk of overall malnutrition during the perioperative period, their clinical nutritional interventions are mostly based on parenteral nutrition with a single infusion of nutritional preparations, and the nutritional status is not significantly improved. However, the incidence of postoperative nutrition-related complications is low. Standardized nutrition interventions should be strengthened in the future.
