Effect of Transcutaneous Electrical Acupoint Stimulation Combined with Transversus Abdominis Plane Block on Postoperative Recovery in Elderly Patients Undergoing Laparoscopic Gastric Cancer Surgery: A Randomized Controlled Trial

Postoperative Ileus and Nonpharmacological Nursing Interventions for Colorectal Surgery: A Systematic Review

PURPOSE

This review evaluates nonpharmacological interventions for postoperative ileus (POI) prevention and treatment.

DESIGN

We systematically reviewed articles from various databases between January 2012 and February 2023 on POI prevention in colorectal surgery patients, emphasizing nursing interventions.

METHODS

Inclusion was based on criteria such as language (English or Turkish), date range, and study type. The risk of bias was evaluated using Cochrane's RoB2 tool.

FINDINGS

Of the 3,497 articles found, 987 unique articles were considered. After title and abstract reviews, 977 articles were excluded, leaving 52 randomized controlled trials for examination. Common interventions included chewing gum, early hydration, acupuncture, and coffee consumption. Compared to control groups, intervention groups had quicker bowel function return, shorter hospital stays, fewer complications, and enhanced quality of life.

CONCLUSION

Nondrug nursing interventions post colorectal surgery can effectively mitigate POI, optimize bowel function, and boost patient satisfaction, warranting their incorporation into post-surgery care protocols.

Intertransverse process block versus subcostal transversus abdominis plane block in patients undergoing laparoscopic radical gastrectomy: a prospective randomized controlled trial

BACKGROUND

Laparoscopic radical gastrectomy has been reported to be associated with substantial trauma and pain. This study compared the impact of ultrasound-(US)-guided, bilateral, double-injection intertransverse process block (ITPB) on postoperative analgesia with subcostal transversus abdominis plane block (TAPB) in patients who were undergoing laparoscopic radical gastrectomy.

METHODS

Sixty-two patients who were undergoing laparoscopic radical gastrectomy surgery under general anesthesia were included. These patients were randomized to either the ITPB group or the TAPB group. Patients in the ITPB group received a double-shot US-guided bilateral ITPB at the thoracic level T6/7 and T9/10 level using ropivacaine (0.3%, 15 mL). Patients in the TAPB group received bilateral subcostal TAPB one injection per side using ropivacaine (0.3%, 30 mL). All patients used a BIS-guided combined intravenous and inhalation anesthesia. The primary outcome was defined as postoperative morphine-equivalent consumption during the first 24 h.

RESULTS

The study recruited 62 patients (31 in each group) for the analysis. A comparatively less postoperative opioid consumption was observed in the ITPB group compared with the subcostal TAPB group within the first 24 h postoperatively (mean [standard deviation-(SD)] morphine-equivalent dose): 27.8 (5.7) mg vs 31.2 (4.4) mg, P < 0.001. The ITPB group showed lower intraoperative opioid use, and statistical significantly lower scores at rest and coughing at 6, 24 h postoperatively. The time to first requiring rescue analgesia was longer in the ITPB group than the subcostal TAPB group (median [IQR]): 8.0 [8.0] vs 6.0 [6.0] h, P = 0.009. The patients in the ITPB group exhibited earlier independent movement, lower incidence of postoperative complications and higher levels of satisfaction (P = 0.021).

CONCLUSION

This study showed that the double-shot bilateral ITPB could reduce opioids consumption and achieve longer and better pain relief. Additionally, it promoted early postoperative activity and improved patient satisfaction.

CiteSpace-based visual analysis on transcutaneous electrical acupoint stimulation of clinical randomized controlled trial studies and its mechanism on perioperative disorders

To systematically present an overview of randomized controlled trials on transcutaneous electrical acupoint stimulation (TEAS) using bibliometric methods, and describe the role and mechanisms of TEAS in most prevalent diseases. Relevant literature was searched in China National Knowledge Infrastructure, Wanfang Data, VIP, SinoMed, PubMed, and Web of Science. The literature was imported and screened into NoteExpress, screened according to inclusion and exclusion criteria, and analyzed using Excel and CiteSpace 6.3R1 software. A total of 1296 documents were included. The number of publications increased annually after 2012. Junlu Wang was the most prolific author. The main research institutions were Peking University, The Third Affiliated Hospital of Zhejiang Chinese Medical University, Shuguang Hospital, and Tongde Hospital of Zhejiang Province. The research hotspots in this field include perioperative care, cancer, pain management, and stroke, primarily focusing on analgesia, immune enhancement, antihypertension, and reduction of gastrointestinal disorders. The main regulatory mechanisms of TEAS include the control of inflammation, oxidative stress, and regulation of the autonomic nervous system. TEAS is most widely used in the elderly, with PC6, ST36, and LI4 being the most frequently studied acupoints in clinical randomized controlled trials. The concept of accelerated rehabilitation is gradually being applied to TEAS, representing an emerging trend for future development. Clinical research on TEAS is rapidly developing, with a focus on applications in cancer and perioperative care. Future research should expand collaboration and conduct high-level clinical and mechanistic studies, which will contribute to the development of standardized protocols and clinical practice.

Transcutaneous electrical acupoint stimulation for immunologic function after surgery in patients with gastrointestinal tumor: a meta-analysis

There is no consensus on whether transcutaneous acupoint electrical stimulation can be used to improve the immune function of postoperative patients with gastrointestinal tumors. This meta-analysis aims to evaluate the effects of transcutaneous electrical acupoint stimulation (TEAS) on postoperative immune function of patients with gastrointestinal tumor and provide evidence-based basis for clinical evaluation. The method used in this study is to systematically searched English databases including PubMed, Cochrane Library (CENTRAL), Excerpta Medica Database (EMbase), Web of Science and Chinese databases including Chinese National Knowledge Infrastructure (CNKI), Wanfang Data, VIP database and China Biomedical Literature Database (SinoMed). Relevant registration platform named Chinese Clinical Trial Registry (ChiCTR) was also searched. Manual search and document tracking are also performed. The aforementioned databases were retrieved for transcutaneous electrical acupoint stimulation for immunologic function after surgery in patients with gastrointestinal tumor randomized controlled trials (RCTs) from inception to 1 November 2022. Meta-analysis was conducted by RevMan5.4.1 software, and the evidence quality was evaluated using Cochrane risk bias evaluation form. In this study, a total of 18 trials with 1618 participants were analyzed. Only two studies were shown to be low risk. The results showed that there were significant differences in cellular immune and inflammatory factors and receptors, such as CD3+, CD4+, CD4+/CD8+, NK, IL-6, TNF-α, sIL-2 R, IL-2 and CRP, had significant effects (P < 0.05) after TEAS intervention on gastrointestinal tumor; however, CD8+ (P = 0.07) and IL-10 (P = 0.26) did not. Judging from the current evidence, TEAS was found to improve the immune function of patients with gastrointestinal tumors after surgery and reduce the level of inflammatory response, worthy of clinical promotion and use.

The effect of transcutaneous electrical acupoint stimulation on postoperative awakening after general anaesthesia: a systematic review and meta-analysis

Background

The existing body of research concerning the impact of transcutaneous electrical acupoint stimulation (TEAS) on early postoperative recovery is marked by a lack of consensus. This meta-analysis, encompassing a systematic review of randomised controlled trials, seeks to critically assess the efficacy of TEAS in relation to awakening from general anaesthesia in the postoperative period.

Methods

The inclusion criteria for this study were peer-reviewed randomised controlled trials that evaluated the influence of TEAS on the process of regaining consciousness following general anaesthesia. A comprehensive search was conducted across several reputable databases, including PubMed, Embase, the Cochrane Library, the China National Knowledge Infrastructure, the VIP Database, the SinoMed Database, and the WANFANG Medical Database. The search was not limited by date, extending from the inception of each database up to December 2023. The methodological quality and risk of bias within the included studies were appraised in accordance with the guidelines outlined in the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1, and its associated tool for assessing risk of bias.

Results

The analysis encompassed 29 studies involving a total of 2,125 patients. Participants in the TEAS group demonstrated a significantly shorter duration to achieve eye-opening [mean difference (MD), -3.16 min; 95% confidence interval (CI), -3.93 to -2.39], endotracheal extubation (MD, -4.28 min; 95% CI, -4.79 to -3.76), and discharge from the post-anaesthesia care unit (MD, -8.04 min; 95% CI, -9.48 to -6.61) when compared to the control group receiving no or sham stimulation. Additionally, the TEAS group exhibited markedly reduced mean arterial blood pressure (MD, -9.00 mmHg; 95% CI, -10.69 to -7.32), heart rate (MD, -7.62 beats/min; 95% CI, -9.02 to -6.22), and plasma concentrations of epinephrine (standardised MD, -0.81; 95% CI, -1.04 to -0.58), norepinephrine (MD, -47.67 pg/ml; 95% CI, -62.88 to -32.46), and cortisol (MD, -110.92 nmol/L; 95% CI, -131.28 to -90.56) at the time of extubation. Furthermore, the incidence of adverse effects, including agitation and coughing, was considerably lower in the TEAS group relative to the control group (odds ratio, 0.30; 95% CI, 0.22-0.40).

Conclusion

The findings of this study indicate that TEAS may hold promise in facilitating the return of consciousness, reducing the interval to awakening post-general anaesthesia, and enhancing the awakening process to be more tranquil and secure with a diminished likelihood of adverse events. However, caution must be exercised in interpreting these results due to the notable publication and geographical biases present among the studies under review. There is an imperative for further high-quality, low-bias research to substantiate these observations.

Transcutaneous electrical acupoint stimulation for prevention of postoperative urinary retention: A systematic review

Introduction

Transcutaneous electrical acupoint stimulation (TEAS) has been proposed for postoperative urinary retention (POUR). This meta-analysis evaluated the effect of TEAS in preventing POUR.

Methods

Databases were searched until February 6, 2023. Randomized controlled trials (RCTs) about TEAS for preventing POUR were included. The primary concern was the incidence of POUR, with post-void residual urine volume as a secondary outcome.

Results

Fourteen studies with 2865 participants were identified. TEAS reduced the incidence of POUR (RR = 0.44, 95%CI = 0.33 to 0.58, P < 0.00001) and decreased the post-void residual urine volume (MD = -75.41 mL, 95%CI = -118.76 to -32.06, P = 0.0007). The preventive effect on POUR was found in patients receiving anorectal, gynecologic, orthopedic and biliary surgery, but not urinary surgery. Dilatational- and continuous-wave TEAS had a great outcome in preventing POUR. Intraoperative TEAS, preoperative and intraoperative TEAS, and postoperative TEAS were beneficial, and TEAS was more beneficial when compared with sham TEAS and blank control. It is nevertheless difficult to rule out publication bias.

Conclusions

TEAS could prevent POUR. Due to insufficient evidence, multicenter, large-sample and high-quality RCTs should be conducted. (Registration:INPLASY202320095).

Effect of transcutaneous electrical acupoint stimulation on postoperative pain in pediatric orthopedic surgery with the enhanced recovery after surgery protocol: a prospective, randomized controlled trial

STUDY OBJECTIVE

To evaluate the safety and effectiveness of transcutaneous electrical acupoint stimulation (TEAS) in postoperative analgesia following pediatric orthopedic surgery with the enhanced recovery after surgery (ERAS) protocol.

DESIGN

Prospective randomized controlled trial.

SETTING

The Seventh Medical Center of the Chinese People's Liberation Army General Hospital.

PARTICIPANTS

Eligible participants were children aged 3-15 years who were scheduled to undergo orthopedic surgery of the lower extremities under general anesthesia.

INTERVENTIONS

A total of 58 children were randomly allocated into two groups: TEAS (n = 29) and sham-TEAS (n = 29). The ERAS protocol was used in both groups. In the TEAS group, the bilateral Hegu (LI4) and Neiguan (PC6) acupoints were stimulated starting from 10 min before anesthetic induction until the completion of surgery. In the sham-TEAS group, the electric stimulator was also connected to the participants; however, electrical stimulation was not applied.

MEASURES

The primary outcome was the severity of pain before leaving the post-anesthesia care unit (PACU) and at postoperative 2 h, 24 h, and 48 h. Pain intensity was measured with the Faces Pain Scale-Revised (FPS-R).

RESULTS

None of the participants had any TEAS-related adverse reactions. In comparison with the sham-TEAS group, FPS-R scores in the TEAS group were significantly decreased before leaving the PACU and at postoperative 2 h and 24 h (p < 0.05). The incidence of emergence agitation, intraoperative consumption of remifentanil, and time to extubation were significantly reduced in the TEAS group. Furthermore, the time to first press of the patient-controlled intravenous analgesia (PCIA) pump was significantly longer, the pressing times of the PCIA pump in 48 h after surgery was significantly decreased, and parental satisfaction was significantly improved (all p < 0.05).

CONCLUSION

TEAS may safely and effectively relieve postoperative pain and reduce the consumption of perioperative analgesia in children following orthopedic surgery with the ERAS protocol.

Analgesic effect of ultrasound-guided bilateral transversus abdominis plane block in laparoscopic gastric cancer

BACKGROUND

Postoperative complications are important factors affecting the survival time and quality of life of patients undergoing radical gastrectomy.

AIM

To investigate and compare the anesthetic effects of intravenous general anesthesia combined with epidural anesthesia or ultrasound-guided bilateral transversus abdominal plane block (TAPB) in gastric cancer patients undergoing laparoscopic radical gastrectomy.

METHODS

The clinical data of 85 patients who underwent laparoscopic radical gastrectomy in our hospital from December 2020 to January 2023 were retrospectively collected and divided into a TAPB group (n = 45) and epidural anesthesia group (n = 40) according to the different anesthesia and analgesia programs used. The TAPB group received general anesthesia combined with TAPB, and the epidural anesthesia group received general anesthesia combined with epidural anesthesia. The pain status, cognitive status, intestinal barrier indicators, recovery quality, and incidence of complications were compared between the two groups.

RESULTS

Compared with the epidural anesthesia group, the TAPB group's visual analog scale scores were significantly lower 6 h, 12 h, 24 h and 48 h after surgery (P < 0.05). The incidence of postoperative cognitive dysfunction (POCD) in the TAPB group was significantly lower than that in the epidural anesthesia group, and the Mini-mental State Examination score 24 h after surgery was significantly higher in the TAPB group than the epidural anesthesia group (P < 0.05). The levels of diamine oxidase and plasma D-lactate were significantly lower in the TAPB group than the epidural anesthesia group 24 h after surgery (P < 0.05). The agitation score and the incidence of agitation during recovery were significantly lower in the TAPB group than epidural anesthesia group (P < 0.05). The total incidence of postoperative complications in the TAPB group was 4.44%, significantly lower than the 20.00% in the epidural anesthesia group (P < 0.05).

CONCLUSION

Compared with epidural anesthesia combined with general anesthesia, TAPB combined with general anesthesia had a good analgesic effect in laparoscopic radical gastrectomy and can further reduce the incidence of POCD and postoperative complications, improve the levels of intestinal barrier indicators, and improve postoperative recovery quality.

Perioperative analgesia in the elderly

The administration of analgesic drugs in elderly patients should take into account age-related physiological changes, loss of efficiency of homeostatic mechanisms, and pharmacological interactions with chronic therapies. Underestimation of pain in patients with impaired cognition is often linked to difficulties in pain assessment. In the preoperative phase, it is essential to assess the physical status, cognitive reserve, and previous chronic pain conditions to plan effective analgesia. Furthermore, an accurate pharmacological history of the patient must be collected to establish any possible interaction with the whole perioperative analgesic plan. The use of analgesic drugs with different mechanisms of action for pain relief in the intraoperative phase is a crucial step to achieve adequate postoperative pain control in older adults. The combined multimodal and opioid-sparing strategy is strongly recommended to reduce side effects. The use of various adjuvants is also preferable. Moreover, the implementation of non-pharmacological approaches may lead to faster recovery. High-quality postoperative analgesia in older patients can be achieved only with a collaborative interdisciplinary team. The aim of this review is to highlight the perioperative pain management strategies in the elderly with a special focus on intraoperative pharmacological interventions.

Transcutaneous Electrical Acupoint Stimulation Improves Postoperative Sleep Quality in Patients Undergoing Laparoscopic Gastrointestinal Tumor Surgery: A Prospective, Randomized Controlled Trial

INTRODUCTION

This study was conducted to observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on the postoperative sleep quality of patients undergoing gastrointestinal tumor surgery and to verify the possible mechanism.

METHODS

Eighty-three patients were allocated to the TEAS or Sham group. Patients in the TEAS group received TEAS treatment (disperse-dense waves; frequency, 2/100 Hz) on bilateral Shenmen (HT7), Neiguan (PC6) and Zusanli (ST36) points for 30 min each time, total three times in the perioperative period. In the Sham group, electrodes were placed; however, no current was given. Sleep quality was assessed on the day before surgery (P1) and the first and third days after surgery (D1 and D3) using the Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS). Postoperative pain was assessed using visual analog scale (VAS) 72 h postoperatively. The incidences of abdominal distension, dizziness, postoperative nausea and vomiting (PONV) and pulmonary complications were recorded. Serum levels of inflammatory cytokines and the expression of key factors of oxidative stress and key molecules of the nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) signal pathway were measured.

RESULTS

TEAS ameliorated sleep quality at D1 and D3 (PSQI P < 0.05, AIS P < 0.05) and decreased postoperative pain as demonstrated by lower VAS scores compared to the Sham group (P < 0.05). The incidences of abdominal distension and PONV were also lower in the TEAS group. Markers of oxidative stress were increased (P < 0.05), and the serum concentration of interleukin-6 (IL-6) was significantly lower in the TEAS group. The key mediators of the Nrf2/ARE pathway were enhanced after TEAS.

CONCLUSION

Perioperative TEAS improved postoperative sleep quality, reduced postoperative pain and alleviated postoperative adverse effects in patients undergoing laparoscopic gastrointestinal tumor surgery resection. This may be associated with activating Nrf2/ARE signal pathway and decreasing its inflammatory actions.
