Electroacupuncture or transcutaneous electroacupuncture for postoperative ileus after abdominal surgery: A systematic review and meta-analysis

Introduction Postoperative ileus occurs frequently following abdominal surgery. Identification of groups at high risk of developing ileus before surgery may allow targeted interventions. This review aimed to identify baseline risk factors for ileus. Methods A systematic review was conducted with reference to PRISMA and MOOSE guidelines. It was registered on PROSPERO (CRD42017068697). Searches of MEDLINE, EMBASE and CENTRAL were undertaken. Studies reporting baseline risk factors for the development of postoperative ileus based on cohort or trial data and published in English were eligible for inclusion. Dual screening of abstracts and full texts was undertaken. Independent dual extraction was performed. Bias assessment was undertaken using the quality in prognostic studies tool. Meta-analysis using a random effects model was undertaken where two or more studies assessed the same variable. Findings Searches identified 2,430 papers, of which 28 were included in qualitative analysis and 12 in quantitative analysis. Definitions and incidence of ileus varied between studies. No consistent significant effect was found for association between prior abdominal surgery, age, body mass index, medical comorbidities or smoking status. Male sex was associated with ileus on meta-analysis (odds ratio 1.12, 95% confidence interval 1.02–1.23), although this may reflect unmeasured factors. The literature shows inconsistent effects of baseline factors on the development of postoperative ileus. A large cohort study using consistent definitions of ileus and factors should be undertaken.

Postoperative ileus is a common and often life-threatening gastrointestinal complication with few management methods available for patients. Integrating acupressure into perioperative care promises to bring benefits into preventing postoperative ileus. This systematic review and meta-analysis aims to evaluate the efficacy of acupressure in identifying the signs and symptoms of postoperative ileus among patients undergoing abdominal surgery. The MEDLINE, EMBASE, Web of Science, CINAHL, China Journal Net and Wanfang databases were searched for high-quality RCTs using keywords such as acupressure, postoperative ileus, abdominal surgery, etc. A total of six studies ([Formula: see text]) were included in this review and meta-analysis. The quality of the literature was found to be uniformly moderate by the Effective Public Health Practice Project (EPHPP) assessment tool. The results of meta-analyses revealed that acupressure could significantly reduce risks for postoperative nausea (OR 0.52, 95% CI 0.39–0.70, [Formula: see text]) and vomiting (OR 0.54, 95% CI 0.39–0.75, [Formula: see text]) compared with the control group, without significant heterogeneity among studies. Meta-analysis of the need for antiemetic drugs suggested that the OR was 0.39 (95% CI 0.20–0.78, [Formula: see text]) with significant heterogeneity among studies. Our results suggested that acupressure might be effective in reducing the incidence of postoperative nausea and vomiting and the need for antiemetic drugs among patients undergoing abdominal surgery. Considering the substantial risk of bias in the articles included, future high-quality RCTs with a rigorous methodology are desirable to provide solid evidence. Furthermore, other signs and symptoms of postoperative ileus should be explored in future.

Analysis Protocol

Introduction: Coffee, a popular and cheap beverage worldwide, may have an important effect on postoperative ileus (POI). However, previous systematic reviews have not clarified whether the effect is due to caffeine or coffee itself, or shortening hospital stay. We will aim to assess the effect of postoperative coffee consumption on POI. Methods: Studies evaluating the effect of postoperative coffee consumption will be searched using the electronic databases and the trial registries. Meta-analyses will be performed using random-effects models. The Grading of Recommendations, Assessment, Development, and Evaluation approach will be used to assess the certainty of evidence.

Full Body

Patients who undergo abdominal surgery under general anesthesia develop hypothermia in 80–90% of the cases within an hour after induction of anesthesia. Side effects include shivering, bleeding, and infection at the surgical site. However, the surgical team applies forced air warming to prevent peri-operative hypothermia, but these methods are insufficient. This study aimed to confirm the optimal application method of forced air warming (FAW) intervention for the prevention of peri-operative hypothermia during abdominal surgery. A systematic review and meta-analysis were conducted to provide a synthesized and critical appraisal of the studies included. We used PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL to systematically search for randomized controlled trials published through March 2020. Twelve studies were systematically reviewed for FAW intervention. FAW intervention effectively prevented peri-operative hypothermia among patients undergoing both open abdominal and laparoscopic surgery. Statistically significant effect size could not be confirmed in cases of only pre- or peri-operative application. The upper body was the primary application area, rather than the lower or full body. These findings could contribute detailed standards and criteria that can be effectively applied in the clinical field performing abdominal surgery.
