Pretreatment with transcutaneous electrical acupoint stimulation to prevent postoperative ileus in patients undergoing laparoscopic colon surgery: study protocol for a randomised controlled trial.

ABSTRACT: INTRODUCTION:Postoperative ileus (POI), a common complication after surgery, severely affects postoperative recovery. It is unclear whether pretreatment with transcutaneous electrical acupoint stimulation (TEAS) can improve recovery from POI. This trial will evaluate the effects of pretreatment with TEAS on POI. METHODS AND ANALYSIS:This will be a prospective, randomised controlled trial. American Society of Anesthesiologists (ASA) physical status classification I-III level patients, aged 18-75 years and scheduled for laparoscopic colon surgery, will be included in the study. It is planned that 146 subjects will be randomised to the TEAS and sham TEAS (STEAS) groups. The groups will undergo two sessions of TEAS/STEAS daily for 3?days before surgery, with a final TEAS/STEAS treatment 30?min before anaesthesia. The primary endpoint of the study will be time to first defaecation. Secondary endpoints will include time to first flatus, time to tolerance of oral diet, GI-2 (composite outcome of time to first defaecation and time to tolerance of oral diet), time to independent walking, length of hospital stay, postoperative pain Visual Analogue Scale score on the first 3?days after surgery, analgesic requirements, complications and plasma concentrations of interferon-? (IFN-?), IFN-?, interleukin-6 (IL-6) and IL-1?. Multiple linear regression will be used to identify independent predictors of outcome measures. ETHICS AND DISSEMINATION:This study has been approved by the Chinese Registered Clinical Trial Ethics Review Committee (No. ChiECRCT-20170084). The results of the trial will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER:This study has been registered with the Chinese Clinical Trial Registry (No. ChiCTR-INR-17013184). TRIAL STATUS:The study was in the recruitment phase at the time of manuscript submission.

Project description:Laparoscopy is performed worldwide due to its limited side effects and optimal treatment efficacy. However, it also has adverse effects, including atelectasis and ischemia-reperfusion injury, due to CO2 accumulation during ventilation in a head-down position, which may result in severe disorders and adversely affecting postoperative recovery, prolonging hospitalization. The present study was performed to assess whether transcutaneous electrical acupoint stimulation (TEAS) protects against lung injury occurring during gynecological laparoscopic surgery. Patients were randomly allocated to two groups: Control group (received no stimulation) and TEAS group (patients treated with TEAS on BL13, LI4 and LU5). The mean arterial pressure, heart rate and oxygen saturation were recorded at the time-points of arriving in the operating room (T0), immediately prior to induction of the pneumoperitoneum (T1), immediately after the end of pneumoperitoneum (T2) and on leaving the operating room (T3). Arterial blood gas analysis was performed to record the pH, determine the partial pressure of carbon dioxide and calculate the oxygenation index (OI) at T0-3. Blood samples were taken from the peripheral vein for determination of the serum concentrations of tumor necrosis factor (TNF)-? and interleukin (IL)-1? at T0 and T3. Post-operative pulmonary complications occurring during the first five days after surgery were also recorded. A total of 100 patients were initially enrolled and 80 patients were analysed. The results indicated that the OI in the control group was significantly lower than that in the TEAS group at the T2 and T3 time-points. The serum concentrations of TNF-? and IL-1? were significantly increased following surgery, while the extent of these increases was lower in the TEAS group compared with that in the control group. The incidence of post-operative pulmonary complications was significantly lower in the TEAS group. It was therefore indicated that TEAS protect against lung injury as a complication of gynecological laparoscopic surgery. The present study was registered at http://www.clinicaltrials.gov prior to enrollment of the patients (no. NCT02850471).

Project description:ImportancePostoperative nausea and vomiting (PONV) gives patients a bad experience and negates their good recovery from surgery.ObjectiveThis trial aims to assess the preventive effectiveness of transcutaneous electrical acupoint stimulation (TEAS) on the incidence of PONV in high-risk surgical patients.DesignThe large sample size, multicenter, evaluator-blinded, and randomized controlled study was conducted between September 3, 2019 to February 6, 2021.SettingThe 12 hospitals were from different Chinese provinces.ParticipantsAfter obtaining ethics approval and written informed consent, 1,655 patients with Apfel score ≥ 3 points were enrolled for selective laparoscopic non-gastrointestinal surgery under general anesthesia.InterventionsPatients were randomly allocated into the TEAS and Sham group with a 1:1 ratio. The TEAS group was stimulated on bilateral Neiguan and Zusanli acupoints after recovery from anesthesia on the surgical day and the next morning for 30 min, while the Sham group received an identical setting as TEAS but without currents delivered. Electronic patient self-reported scale was used to evaluate and record the occurrence of PONV.Main outcomes and measuresPrimary clinical end point is the incidence of PONV which was defined as at least one incidence of nausea, retching, or vomiting after operation within postoperative 24 h.ResultsCompared with the Sham treatment, the TEAS lowered the PONV incidence by 4.8% (29.4 vs. 34.2%, P = 0.036) and vomiting incidence by 7.4% (10.4 vs. 17.8%, P < 0.001). TEAS also lowered persistent nausea incidence and PONV scores and decreased PONV related complications and Quality of Recovery-40 scores (P < 0.05). TEAS lowered the 24 h PONV risk by 20% (OR, 0.80, 95% CI, 0.65 -0.98; P = 0.032), and lowered hazard ratio by 17% (HR, 0.83, 95% CI, 0.70-0.99; P = 0.035). Both TEAS and palonosetron were the independent PONV risk protective factors for 24 h PONV incidence and cumulative PONV incidence. The combination of TEAS and palonosetron was the most effective strategy to reduce the PONV incidence (P < 0.001).Conclusions and relevanceTEAS attenuated the PONV incidence and severity in high-risk surgical patients and may be applied clinically as a complement therapy to prevent PONV.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/NCT04043247, identifier: NCT04043247.

Project description:Background: No specific treatment is available for postoperative cognitive dysfunction (POCD). Recently, interest in the prevention of POCD during the perioperative period has increased. Although some studies suggest that transcutaneous electrical acupoint stimulation (TEAS) may be beneficial, the relevant evidence remains uncertain. Objective: To evaluate the preventive effects of TEAS on POCD. Methods: Seven databases including PubMed, EMBASE, CENTRAL, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Wanfang Database, and Chinese Biomedical Literature Database (CBM) were electronically searched up to April 2021. Two reviewers independently selected the studies, collected data, and assessed the risks of bias and grading of recommendations, assessment, development, and evaluations certainty of the evidence. A meta-analysis of the incidence of POCD, cognitive function score, pain, adverse reactions, and length of hospital stay after surgery was also performed. Results: Twenty-nine randomized controlled trials with 1,994 participants were included. The results of the meta-analysis showed that the TEAS group has a significantly lower incidence of POCD compared with the control group on postoperative days 1 [OR = 0.33 (95%CI: 0.23, 0.47); p < 0.001, I 2 = 0%, moderate certainty], 3 [OR = 0.38 (95%CI: 0.29, 0.50); p < 0.001, I 2 = 0%, low certainty], and 7 [OR = 0.51 (95%CI: 0.32, 0.81); p = 0.005, I 2 = 0%, low certainty] but not on day 5 (p > 0.05, low certainty). Moreover, TEAS improved the Mini-Mental State Examination scores on postoperative days 1, 3, and 7 [MD = 2.44 (95%CI: 1.61, 3.27); p < 0.001, I 2 = 93%, low certainty]; [MD = 2.07 (95%CI: 1.53, 2.62); p < 0.001, I 2 = 87%, low certainty]; and [MD = 0.49 (95%CI: 0.18, 0.79); p = 0.002, I 2 = 21%, low certainty], respectively, but not on day 5 (p > 0.05, very low certainty). TEAS promoted a postoperative analgesic effect within 24 h after surgery. Furthermore, patients receiving TEAS showed a lower incidence of postoperative nausea and vomiting and a shorter hospital stay. Conclusions: Limited evidence suggests that the application of TEAS in the perioperative period is associated with a reduced POCD rate and a protected early postoperative cognitive function.

Project description:BackgroundThis study aimed to evaluate the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative cognitive dysfunction (POCD) in older patients who were diagnosed with gastrointestinal tumor and received radical resection of gastrointestinal tumors under general anesthesia.MethodsA total of 68 patients who received radical resection of gastrointestinal tumors under general anesthesia were randomly divided into two groups. TEAS group patients received TEAS treatment. The treatment time was 30 min before the induction of anesthesia until the end of the surgery, 1 day before operation and from the first day to the third day after the operation. Except on the day of surgery, we treated the patients for 30 min once a day. In the sham TEAS group, the electronic stimulation was not applied and the treatment was the same as the TEAS group. The primary outcome was perioperative cognition evaluated by the Mini-Mental State Examination (MMSE) and secondary outcomes were the perioperative level of interleukin-6 (IL-6), S100 calcium-binding protein β (S100β), and C-reactive protein (CRP).ResultsThe postoperative score of MMSE, orientation, memory, and short-term recall in the sham TEAS group was significantly lower than the preoperative and TEAS group (P < 0.05). The incidence of POCD in the TEAS group (21.88%) was lower than those in the sham TEAS group (40.63%). S100β, IL-6, and CRP in the TEAS group were significantly lower than those in the sham TEAS group on the third day after the operation (P< 0.05). Postoperative S100β, IL-6, and CRP in two groups were significantly higher than those before operation except for S100β on the third day after the operation in the TEAS group (P < 0.05).ConclusionsPerioperative TEAS treatment reduced the postoperative inflammatory response and increased the postoperative cognitive function score and decrease the incidence of POCD in geriatric patients with gastrointestinal tumor.Trial registrationClinicalTrials.gov NCT04606888 .

Project description:ObjectiveThis systematic review and meta-analysis aimed to evaluate the preventive effect of transcutaneous electrical acupoint stimulation on postoperative delirium in elderly surgical patients.MethodsPubMed, CENTRAL, China National Knowledge Infrastructure, and WanFang databases were searched for randomized controlled trials regarding the effect of transcutaneous electrical acupoint stimulation on preventing postoperative delirium in elderly patients undergoing any type of surgery. The primary outcome was the incidence of postoperative delirium. The secondary outcome was the duration of postoperative delirium. All analyses were conducted using RevMan 5.3 and Stata 13.0 software.ResultsTwelve trials with 991 participants were included, and most of them were at high/unclear risk of bias. Meta-analysis showed transcutaneous electrical acupoint stimulation could reduce the incidence of postoperative delirium (RR = 0.40, 95%CI = 0.29 to 0.55, p < 0.00001) and shorten the duration of postoperative delirium (MD = -0.97 days, 95%CI = -1.72 to -0.22, p = 0.01). Subgroup analyses demonstrated that transcutaneous electrical acupoint stimulation reduced the incidence of postoperative delirium in elderly patients undergoing orthopedic surgery and thoracic surgery, but not digestive surgery; transcutaneous electrical acupoint stimulation with dilatational wave and with continuous wave were both beneficial; and transcutaneous electrical acupoint stimulation was favored when compared to blank and sham control.ConclusionTranscutaneous electrical acupoint stimulation could reduce the incidence of postoperative delirium and shorten the duration of postoperative delirium in elderly surgical patients. The findings should be interpreted with caution due to weak evidence. High-quality, large sample, and multi-center trials are needed to further confirm the preliminary findings.Systematic review registration: https://inplasy.com/inplasy-2022-7-0096/, identifier: INPLASY202270096.
