ABSTRACT
Abstract Background Early mobilization after surgery is a cornerstone of the Enhanced Recovery After Surgery (ERAS) programs in total hip arthroplasty (THA) or total knee arthroplasty (TKA). Our goal was to determine the time to mobilization after this surgery and the factors associated with early mobilization. Methods This was a predefined substudy of the POWER.2 study, a prospective cohort study conducted in patients undergoing THA and TKA at 131 Spanish hospitals. The primary outcome was the time until mobilization after surgery as well as determining those perioperative factors associated with early mobilization after surgery. Results A total of 6093 patients were included. The median time to achieve mobilization after the end of the surgery was 24 hours [16-30]. 4,222 (69.3%) patients moved in ≤ 24 hours after surgery. Local anesthesia [OR = 0.80 (95% confidence interval [CI]: 0.72-0.90); p= 0.001], surgery performed in a self-declared ERAS center [OR = 0.57 (95% CI: 0.55-0.60); p< 0.001], mean adherence to ERAS items [OR = 0.93 (95% CI: 0.92-0.93); p< 0.001], and preoperative hemoglobin [OR = 0.97 (95% CI: 0.96-0.98); p< 0.001] were associated with shorter time to mobilization. Conclusions Most THA and TKA patients mobilize in the first postoperative day, early time to mobilization was associated with the compliance with ERAS protocols, preoperative hemoglobin, and local anesthesia, and with the absence of a urinary catheter, surgical drains, epidural analgesia, and postoperative complications. The perioperative elements that are associated with early mobilization are mostly modifiable, so there is room for improvement.

@#Objective To explore the independent risk factors for postoperative retention of urinary catheters in the ward of lung tumor patients due to urinary retention under the concept of enhanced recovery after surgery (ERAS). Methods Seventy-five patients with lung tumors who had urinary catheters left in the postoperative ward between June 2019 and August 2019 were selected as a case group, and 75 patients with lung tumors who did not have urinary catheters in the perioperative period as a control group. Independent risk factors for indwelling urinary catheters in the postoperative ward were screened by univariate and multiple-variate logistic stepwise regression analysis. Results There were 45 males and 30 females in the case group with an average age of 55.33±10.78 years, 28 males and 47 females in the control group with an average age of 57.12±10.06 years. Univariate analysis showed that gender, operative time>2 h, intraoperative fluid volume≥1 200 mL, and fluid volume within 6 h of returning to the ward after surgery>1 200 mL were associated with the occurrence of indwelling urinary catheters in patients with lung tumors in postoperative wards (P<0.05). Multiple-variate logistic regression showed that male (OR=2.311, 95%CI 1.173-4.552, P=0.015), infusion volume within 6 h of returning to the ward after surgery>1 200 mL (OR=2.491, 95%CI 1.149-5.401, P=0.021) and intraoperative infusion volume≥1 200 mL (OR=2.105, 95%CI 1.022-4.340, P=0.044) were independent risk factors for postoperative retention of urinary catheters in patients with lung tumors. Conclusion The occurrence of indwelling urinary catheter in lung tumor patients under the ERAS concept is the result of a combination of factors, and patients who are male, have infusion volume>1 200 mL within 6 h of returning to the ward after surgery, and have intraoperative infusion volume≥1 200 mL are the high-risk group for postoperative ward indwelling urinary catheter, and health care personnel should strengthen the assessment and observation, provide targeted health education, appropriately control the perioperative fluid volume, and take other measures to reduce the occurrence of indwelling urinary catheters due to urinary retention postoperatively in ward.
ABSTRACT
Objective:To study the effect of enhanced recovery after surgery (ERAS) on intestinal function and gut microbiota changes in patients who underwent laparoscopic gastrectomy.Methods:From Aug. 2018 to Dec. 2019, 80 patients who underwent laparoscopic radical D2 gastrectomy for gastric cancer in the first Department of Gastrointestinal Surgery of Yantai Yuhuangding Hospital were selected. According to whether it adopts ERAS treatment or not, patients were divided into 2 groups (n=40) : ERAS group and traditional perioperative treatment group. The time of postoperative bowel sounds, the time of first exhaust and defecation, the proportion of antibiotic-related diarrhea and surgical site infection (SSI) were recorded. Stools were collected before operation, first time after operation, 1, 2 weeks and 1 month after operation. 16S rRNA sequencing method was used to identify the diversity and species of gut microbiota. The diversity index of intestinal flora in the perioperative period and changes in the proportion of probiotics (bifidobacterium and lactobacillus) were compared.Results:The appearance time of bowel sounds, the first exhaust and defecation time [ (16.25±6.41) h, (23.95±6.02) h, (34.95±9.34) h] in ERAS group were significantly earlier than those in the traditional treatment group [ (22.3±6.49) h, (28.45±7.12) h, (48.1±15.64) h], and the difference was statistically significant ( P<0.05) . The incidence of antibiotic-related diarrhea was higher in the traditional treatment group (3/40) than in ERAS group (1/40) , but the difference was not statistically significant ( P>0.05) . The ratio of postoperative SSI was slightly higher in ERAS group, but the difference was not statistically significant ( P>0.05) . In the perioperative period, the intestinal flora diversity index (Chao1 and Shannon index) and the proportion of probiotics (lactobacillus acidophilus and bifidobacterium) were not significantly different between the two groups before surgery ( P>0.05) ; while at the first time, one week, 2 weeks after the operation, and 1 month after the operation, ERAS group was higher than the traditional group ( P<0.05) ; and at each postoperative time point, the traditional group decreased significantly than the ERAS group. The first time decrease was the largest, ( P<0.05) ; With the passage of time after operation, the diversity of intestinal flora and the proportion of probiotics gradually recovered. By 1 month after operation, the two groups did not return to the preoperative gut microbiota diversity state or proportion. Conclusion:The concept of enhanced recovery after surgery (ERAS) promotes the recovery of intestinal function in patients with gastric cancer, does not reduce the proportion of antibiotic-associated diarrhea (AAD) or surgical site infections (SSI) , and maintains the diversity of gut microbiota balance and stability.
ABSTRACT
Enhanced recovery after surgery (ERAS) represents a transformation to the evidence-based medicine paradigm in perioperative treatment. ERAS aims to reduce recovery time, postoperative complications, and healthcare costs. Here, we review the development and principal components of ERAS along with its application in abdominal tumor surgery. The benefits and feasibility of the ERAS protocol have been demonstrated in clinical practice, particularly in relation to colorectal surgery.
ABSTRACT
Objective To discuss outcome and safety after implementation of enhanced recovery after surgery(ERAS) protocols to patients who underwent robotic assisted radical cystectomy (RARC) with intracorporeal orthotopic "U" shaped ileal neobladder creation using STAPLER technique.Methods Between October 2014 and April 2019,71 patients(59 males and 12 females)with MIBC (Muscle Invasive Bladder Cancer) who underwent RARC with intracorporeal urinary diversion using orthotopic "U" shaped ileal neobladder in Zhejiang Provincial People's Hospital (People's Hospital of Hangzhou Medical College) were studied retrospectively.They had an average age of (65.2 ± 5.6)y and BMI of (22.18 ± 3.75) kg/m2.The median age-adjusted charlson comorbidity index (aCCI) was 4,median ASA score was 2.All patients underwent these inspections pre-RARC:chest Xray,vascular ultrasound (jugular vein included),abdominal ultrasound,CT urography,cystoscopy with biopsy or TURBT(trans-urethral resection of a bladder tumour).All patients were pathological diagnosed with MIBC,with no evidence of systemic metastasis and no history of radiotherapy,systemic chemotherapy and open abdominal surgery before RARC.All 71 patients received RARC with intracorporeal orthotopic "U" shaped ileal neobladder creation using STAPLER technique.Between October 2014 and September 2016,37 cases (29 males and 8 females) were managed without ERAS protocols perioperatively.They had an average age of (65.3 ±5.7)y and BMI of (23.66 ± 3.47)kg/m2.The median aCCI was 4,median ASA score was 2.Between October 2016 and April 2019,another group of 34 cases (30 males and 4 females) were managed with ERAS protocols including nutritional assessment,thrombosis prevention,pain assessment and management,perioperative diet management etc.They had an average age of (64.5 ± 4.3) y and BMI of (21.87 ± 4.85) kg/m2.The median aCCI was 4,median ASA score was 2.There were no statistical significance between the two groups with regard to general information.Surgical and follow-up data were collected for all patients.Results Surgeries were successful in all 71 cases with postoperative follow up for 3-51 months.In ERAS group,there were 22 cases in pT2 and 12 cases pT3 according to classification of malignant tumours:with 2 cases of incidental prostate cancer (IPCa).In non-ERAS group,pT2 in 25 cases and pT3 in 12 cases:with 1 case of IPCa.Statistical significance were observed between groups with regard to the first anal exhaust time [(20.5 ± 18.7) h vs.(29.9 ± 17.4)h,P =0.032],the first defecation time [(72.6 ±27.1)h vs.(88.7 ±35.8)h,P =0.004],length of hospital stay after surgey [(14.1 ± 3.3) d vs.(16.2 ± 4.8) d,P =0.037],numeric rating scales (NRS) Pain Score 8.0,24.0,48.0 h after surgery [(3.2 ±0.5)vs.(3.6 ±0.8),P =0.015;(1.9 ±0.3) vs.(2.2 ± 0.6),P =0.011;(1.3 ± 0.4) vs.(1.6 ± 0.7),P =0.032],respectively.There were no significance between groups with regard to operating time [(290 ± 65) min vs.(282 ± 46) min,P =O.549],intraoperative blood loss [(190.5 ± 235.6) ml vs.(221.1 ± 250.3) ml,P =0.438],transfusion rate [5.9％ (2/34) vs.8.1％ (3/37),P =0.922],readmission within 30 days after surgery [2.9％ (1/34) vs.5.4％ (2/37),P =0.940],early severe complications(within 30 days) [2.9％ (1/34) vs.2.7％ (1/37),P =0.940],late severe complications (after 30 days) [5.9％ (2/34) vs.8.1％ (3/37),P =0.922].Conclusions The implementation of ERAS protocols to patients who underwent RARC with intracorporeal orthotopic "U" shaped ileal neobladder using STAPLER technique is safe and effective.It can reduce postoperative pain and hospital stay,shorten bowel recovery time,improve early functional recovery without increasing major complications.This adoption should be encouraged.
ABSTRACT
@# The concept of enhanced recovery after surgery (ERAS) was firstly demonstrated in practice by the Danish scholar Henrik Kehlet in the early 2000s. At present, the ERAS concept has been widely used in a variety of surgical fields, but its application in esophageal cancer surgery is still limited. The new esophageal ERAS guidelines issued by ERAS Association bring new opportunities for the application and promotion of esophageal cancer surgery. Combined with the current situation of esophageal cancer surgery in China and related literature, in this paper we discuss the specific measures of ERAS concept in perioperative application of esophageal cancer in China.
ABSTRACT
@#Objective To explore the feasibility of decompression without gastric tube after minimally invasive esophageal cancer surgery. Methods Seventy-two patients who underwent minimally invasive esophageal cancer resection at the Department of Thoracic Surgery, The Second Affiliated Hospital of Harbin Medical University from 2016 to 2018 were selected as a trial group including 68 males and 4 females with an average age of 58.5±7.9 years, who did not use gastric tube for gastrointestinal decompression after surgery. Seventy patients who underwent the same operation from 2013 to 2015 were selected as the control group, including 68 males and 2 females, with an average age of 59.1±6.9 years, who were indwelled with gastric tube for decompression after surgery. We observed and compared the intraoperative and postoperative indicators and complications of the two groups. Results There were no significant differences between the two groups in operation time, intraoperative blood loss, postoperative level of serum albumin, postoperative nasal jejunal nutrition, whether to enter the ICU postoperatively, death within 30 days after surgery, anastomotic leakage, lung infection, vomiting, bloating or hoarseness (P>0.05). No gastroparesis occurred in either group. Compared with the control group, the recovery time of the bowel sounds and the first exhaust time after the indwelling in the trial group were significantly shorter, and the total hospitalization cost, the incidence of nausea, sore throat, cough, foreign body sensation and sputum difficulty were significantly lower (P<0.05). Conclusion It is feasible to remove the gastric tube for gastrointestinal decompression after minimally invasive esophageal cancer surgery, which will not increase the incidence of postoperative complications, instead, accelerate the postoperative recovery of patients.
ABSTRACT
@#Objective To investigate the preoperative psychological state of patients with pulmonary nodules in order to make the content of the education more "individualized and humanized". Methods We conducted a consecutive questionnaire study for 107 patients who were planning to undergo pulmonary resection surgery from May 2018 to July 2018 in our department. There were 54 males and 53 females with an average age of 56.8±11.2 years. The questionnaire content included two parts: personal basic information and 20 questions about surgery, complications, follow-up and hospitalization expense. Results There were 60.7% of the patients diagnosed with pulmonary nodules by CT scan during physical examination, and 52.3% of the patients had strong will to undergo pulmonary surgery to resect nodules; 64.5% of patients wanted doctors to tell them the extent of the disease and whether the tumor could be cured by surgery, and 30.0%of patients concerned whether chief surgeon would complete the whole surgery. The surgery risk and postoperative complications were ignored by patients easily (5.6% and 14.9% respectively). The hospital expenses were not the primary concern of patients. Only 1.9% of patients believed that doctors used nonessentials which deliberately led to increased costs. Network follow-up was accepted by most patients (94.4%). Conclusion It will contribute to improve preoperative education rationality and effectiveness by understanding true psychological state of patients.
ABSTRACT
Objective To study the clinical value of enhanced recovery after surgery (ERAS) in the perioperative treatment of type Ⅰ (Todami,1975) biliary dilatation (BD) of children.Methods To retrospectively analyze the data of children with type Ⅰ BD who were treated in the General Surgery Department of Zhengzhou Children's Hospital from June 2014 to May 2018.A total of twenty children with type Ⅰ BD treated with ERAS and 20 children treated with the traditional method in our department were selected in this study using the random number table method.Postoperative indicators (including operation time,first defecation time,changes in amylase in blood and abdominal cavity exudates,length of hospital stay,and hospitalization fee) and relevant postoperative complications (including sore throat,nausea and vomiting,urethral pain,upper respiratory tract infection,incision wound infection,adhesive intestinal obstruction,anastomotic leakage and pancreatic fistula) of the ERAS group and the control group were compared.Results The first defecation time,length of hospital stay and hospitalization fee were significantly lower in the ERAS group than the control group (all P ＜ 0.05) [first defecation time (1.98 ± 0.25) d vs.(2.25 ± 0.31) d;length of hospital stay (6.91 ± 1.25) d vs.(9.95 ± 1.53) d;hospitalization fee (23.32 ± 2.25)thousand yuan vs.(25.99 ±3.10) thousand yuan].Moreover,the incidences of sore throat,nausea and vomiting,urethral pain and upper respiratory tract infection were significantly lower in the ERAS group than the control group (all P ＜ 0.05) [the incidences of sore throat (5.0％ vs.45.0％);the incidences of sickness and vomiting (5.0％ vs.30.0％);the incidences of urethral pain (5.0％ vs.45.0％);the incidences of upper respiratory tract infection (5.0％ vs.40.0％)].On the other hand,there were no significant differences in the mean operation times,changes in amylase levels in the blood or abdominal cavity exudates,incision wound infection,and incidences of adhesive intestinal obstruction,anastomotic leakage and pancreatic fistula (all P ＞ 0.05).Conclusions ERAS for type Ⅰ BD surgery was safe and reliable in children.It effectively promoted recovery of postoperative gastrointestinal function and reduced the incidence of complications.
ABSTRACT
@#Objective To report our experience with enhanced recovery after surgery (ERAS) protocol in patients undergoing transapical transcatheter aortic valve implantation (TAVI) and to determine perioperative predictors for ERAS failure. Methods Between May 2018 and January 2019, 80 patients undergoing TAVI in our hospital were recruited. Among them, 40 patients (24 males, 16 females, aged 73.0±5.0 years) successfully received ERAS, defined as successful extubation in operating room (an ERAS group) and the other 40 patients (28 males, 12 females, aged 73.0±7.0 years, a non-ERAS group) failed to perform ERAS. Results Compared with the non-ERAS group, patients in the ERAS group were associated with a significantly lower incidence of postoperative complications (30.0% vs. 52.5%, P=0.04), shorter postoperative ICU stay (2.2±0.4 d vs. 4.0±4.8 d, P=0.00) and hospital stay (7.0±2.3 d vs. 9.5±4.8 d, P=0.00), and less medical cost (311±20 thousand yuan vs. 347±80 thousand yuan, P=0.00). Independent predictors of ERAS failure were poor preoperative heart function and elevated B-type natriuretic peptides. Conclusion ERAS protocol is feasible and effective in patients undergoing TAVI. Poor preoperative heart function is an independent predictor of failure in early extubation which, in turn, is associated with prolonged ICU and hospital stay and dramatic worsening of patient outcomes.
ABSTRACT
Surgery plays a pivotal role in the treatment of certain diseases,which in turn promotes the development of enhanced recovery after surgery (ERAS). However,with the renewal of concept and technology,it is gradually realized that the key to a successful treatment is not only surgery itself but also preoperative and postoperative management. Patientbased perioperative management is closely related to the prognosis of the disease. Therefore,“perioperative medicine”and“perioperative surgical home (PSH)”are gaining more and more attention from all over the world. These novel concepts aim to cover the whole disease treatment process and improve the prognosis.
ABSTRACT
Introducción: El concepto de protocolos de recuperación rápida o precoz fue insertado en la práctica clínica por Henrik Kehlet en 1997, con el objetivo de mejorar la calidad en los cuidados perioperatorios y disminuir la morbilidad y mortalidad. Objetivo: Determinar que la implementación de los protocolos en cirugía cardiaca ya no constituye una utopía. Métodos: La búsqueda bibliográfica estuvo constituida por todos los artículos publicados que evaluaron la utilidad de los protocolos de recuperación rápida o precoz. Desarrollo: Los protocolos de recuperación precoz han sido desarrollados durante décadas y abarcan un conjunto de acciones que cubren todo el periodo perioperatorio. Para lograr la completa adherencia se necesita de un equipo multidisciplinario. Su implementación comenzó en la cirugía colorectal y fueron gradualmente expandidos y adaptados a casi todas la especialidades quirúrgicas. En la cirugía cardiaca por razones no específicas, que incluyen el uso de la circulación extracorpórea, la implementación ha sido demorada pero la evidencia científica existente, aunque no es suficiente, muestra que la adherencia a estos influye de manera positiva en la recuperación de los enfermos, por lo que surge la necesidad de estandarizarlos. Conclusiones: La implementación de estos protocolos en la cardiocirugía ya es una realidad. En abril de 2017 se constituyó la sociedad responsable de dicho proceso, cuyo lema es el de optimizar los cuidados perioperatorios a través de un análisis colaborativo, el consenso de expertos y la diseminación de las mejores prácticas(AU)
Introduction: The concept of rapid or early recovery protocols was inserted into clinical practice by Henrik Kehlet in 1997, with the aim of improving the quality of perioperative care and decreasing morbidity and mortality. Objective: To determine that the implementation of protocols in heart surgery is no longer a utopia. Methods: The bibliographic search was made up of all the published articles that evaluated the usefulness of the rapid or early recovery protocols. Development: Early recovery protocols have been developed for decades and comprise a set of actions that cover the entire perioperative period. A multidisciplinary team is needed to achieve complete adherence. Its implementation began in colorectal surgery and it was gradually expanded and adapted to almost all surgical specialties. In heart surgery for non-specific reasons, including the use of extracorporeal circulation, the implementation has been delayed but the existing scientific evidence, although not enough, shows that adherence to these protocols influences positively the recovery of patients; so, the need to standardize them has arisen. Conclusions: The implementation of these protocols in heart surgery is now a reality. In April 2017, the company responsible for this process was created, whose motto is to optimize perioperative care through a collaborative analysis, consensus of experts and the dissemination of best practices(AU)

Objective@#To investigate the value and feasibility of C reactive protein (CRP) in predicting postoperative anastomotic leakage in rectal cancer patients with enhanced recovery after surgery (ERAS) for safer implementation of this ERAS.@*Methods@#A cohort study on serum CRP of 455 rectal cancer patients undergoing laparoscopic radical resection according to the ERAS procedure at Gastrointestinal Unit of General Surgery Department, Guangdong General Hospital from August 2014 to June 2017 was retrospectively carried out. The serum CRP level was measured before operation and at postoperative days 1-7, and the serum CRP level of the groups with and without anastomotic leakage was compared to analyze its prediction for anastomotic leakage. Diagnostic standard of anastomotic leakage was based on the definition of postoperative anastomotic leakage in rectal cancer from International Study Group of Rectal Cancer (ISREC) : (1) Postoperative localized or diffuse peritonitis occurred, or fecal liquid was found from the abdominal drainage tube; (2) When anastomotic leakage was uncertain, peritoneal or pelvic computed tomography scan should be used to confirm.@*Results@#All the 455 patients underwent surgery successfully, and 41 patients (9.0%) had anastomotic leakage postoperatively. Patients with anastomotic leakage were diagnosed (4.0 ± 2.0) days postoperatively, of whom 8 cases (19.5%) were diagnosed more than 5 days postoperatively. Serum CRP levels in patients with anastomotic leakage continued to increase within 1-4 days postoperatively[ (50.04 ± 27.98) mg/L to (122.75 ± 52.98) mg/L]and decreased 5 days postoperatively[ (92.02 ± 58.26) mg/L], both were higher than those of non-anastomotic leakage group, and the difference was statistically significant (all P < 0.05, except postoperative day 2) . The serum CRP level of non-anastomotic leakage group reached the peak on the second postoperative day[ (83.10 ± 37.45) mg/L] and decreased 3 days postoperatively[ (48.01 ± 27.59) mg/L]. The ROC curve was drawn with the anastomotic leakage as the state variable, and the CRP level as the detection variable. The area under the curve (AUC) at postoperative 1, 2, 4, 5, 6 and 7 days was 0.74, 0.58, 0.83, 0.82, 0.65, and 0.70, respectively. The maximum was at postoperative day 3[0.93 (95%CI: 0.86-0.99) ]. The Youden index was 0.72, and the threshold of CRP was 80.09 mg/L, as the cut-off point to predict anastomotic leakage, with sensitivity, specificity, and positive predictive value of 79.3%, 92.3%, and 74.2%, respectively.@*Conclusions@#Monitoring the postoperative serum CRP level can help predict the occurrence of anastomotic leakage after laparoscopic surgery for rectal cancer. When the serum CRP level is > 80.09 mg/L on the third postoperative day, the CRP level has the largest value in predicting postoperative anastomotic leakage, and the safety of ERAS has a certain clinical significance as well.
ABSTRACT
Objective?To evaluate the effect on removal of ovarian cyst by laparoendoscopic single site surgery and enhanced recovery after surgery (ERAS).?Methods?A prospective, single-institution study was performed for patients who were diagnosed benign ovarian cyst, underwent removal ovarian cyst, and adopted ERAS nursing care from June 2015 to June 2017. 40 patients who adopted laparo-endoscopic single site surgery were experimental group and 40 patients who adopted traditional laparoscopy surgery were control group. We compared the operation time, blood loss volume during operation, the time of getting out-of bed after operation, the postoperative exhausting time, the defecation time after surgery, the incidence of postoperative febrile and other complications, the time of hospital stay, and hospitalization expenses between the two groups. The measurement data was tested by t test, and the counting data was tested by χ2 test, which was statistically significant with P < 0.05.?Results?The results showed that the time of getting out-of bed after operation, the postoperative exhausting time, the defecation time after surgery and the time of hospital stay in experimental group was significantly shorter than the control group;Meanwhile the hospitalization expense was lower than the control group. These results were statistically significant (P < 0.05). While there was not statistically significant in the operation time, blood loss volume during operation, and the incidence of postoperative febrile and other complications between the experimental group and the control group (P > 0.05) .?Conclusion?ERAS combined with laparo-endoscopic single site surgery is helpful to the reduction of hospitalization cost and the clinical promotion and application.
ABSTRACT
@#Objective We conducted a questionnaire study who attended the First West China Forum on Chest Enhanced Recovery after Surgery (ERAS) in order to analyze whether it can improve the knowledge of ERAS and how to organize an effective meeting. Methods We analyzed 188 questionnaires from the representatives of the First West China Forum on Chest ERAS after the meeting which included two parts: one was the personal basic information and institution of respondents, and the other was the opinion of the content setting and suggestion for the next forum. Results A percentage of 97.7% of participants believed that this forum contributed to improving their understanding of ERAS and 65.3% of them will put the concept of ERAS into practice after the meeting. The exchange of experience and project communication of ERAS were the most useful agendas approved by representatives while expert lectures should be more appropriate (18.1%). Arrangement for topic discussion and enough time for discussion were supported by 93.1%and 98.9% of the representatives respectively. Multi-center project discussion (80.9%) and interactive sessions especially WeChat interaction (74.0%) should be added on ERAS forum. Conclusion Reasonable agenda settings are beneficial to improve the understanding and compliance of application of ERAS.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) on gastric emptying in patients undergoing selective surgery based on velocity of gastric emptying by ultrasonography.</p><p><b>METHODS</b>A total of 75 patients with selective operation of subarachnoid block at lower limb in the afternoon were randomly assigned to a TEAS group, a sham group and a control group, 25 patients in each one. All the patients were provided with semi-fluid diet at 8 a.m. The TEAS group was treated with TEAS 5 min after semi-fluid diets at bilateral Zusanli (ST 36) and Neiguan (PC 6) for 30 min, with frequency of 5 Hz and intensity which was 1 mA lower than the tolerance threshold. The sham group patients were stimulated at the same acupoints with current intensity which was 1 mA lower than the sensory threshold. The control group received no treatment. On the day of operation, and ultrasonography was given at time of empty stomach (T0), immediately after the semi-fluid diets (T1), and every 30 min after diets (T2-T6), respectively, to measure the gastric content and emptying time at semire-clining position and right lateral position.</p><p><b>RESULTS</b>The volume of gastric content in the three groups at T3-T6 was significantly less than that at T1 (all<0.05). The volume of gastric content at T4-T6 at semire-clining position in the TEAS group was significantly less than that in the control group and sham group (all<0.05). The volume of gastric content at T5-T6 at right lateral position in the TEAS group was significantly less than that in the control group and sham group (all<0.05). The gastric emptying time in the TEAS group was significantly less than that in the control group and sham group (both<0.05).</p><p><b>CONCLUSION</b>The gastric emptying velocity could be evaluated by ultrasonography. TEAS could improve the velocity of gastric emptying and reduce the gastric emptying time.</p>
