Background: Although, some clinical trials investigated the maternal and neonatal effect of fentanyl as a premedication before induction of general anesthesia in cesarean section, to the best of our knowledge, there is no systematic review to summarize these results. Objectives: The present systematic review and meta-analysis evaluated the maternal and neonatal effect of intravenous fentanyl as a premedication before induction of general anesthesia in cesarean section. Methods: The databases of Pubmed, Embase, Scopus and Cochrane library were searched till July 2017 to identify randomized clinical trials which evaluated the effects of intravenous fentanyl as a premedication before induction of general anesthesia compared with placebo on neonate first and fifth minute Apgar score and maternal heart rate and mean arterial pressure (MAP) in cesarean section. Standard Mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. Results: The present systematic review and meta-analysis consisted of three clinical trials including 180 women in labor. Considering the results of meta-analysis, there is no significant differences between fentanyl and placebo in the case of Apgar score at 1 minute; however, the Apgar score of 5 minutes was significantly lower in fentanyl group compared with placebo (SMD -0.68, 95%CI: - 0.98, -0.38, p<0.001). In the term of maternal hemodynamics, the heart rate (SMD -0.43, 95%CI: - 0.72, -0.13, p=0.004) and MAP (SMD -0.78, 95% CI: -1.09, -0.48, p<0.001) in fentanyl group were significantly lower compared with placebo group. Conclusion: The present meta-analysis showed that using intravenous fentanyl as a premedication before induction of general anesthesia had adverse effects on neonate Apgar score. However, it had positive effects on preventing adverse consequences of intubation on maternal hemodynamics.

Abstract Purpose Tracheal tube introducers and stylets remain some of the most widely used devices for aiding practitioners in performing endotracheal intubation (ETI). The purpose of this systematic review is to evaluate the efficacy of tracheal tube introducers and stylets for ETI in the prehospital setting. Methods A literature search was conducted on the 2nd of March 2021 across PubMed, Embase (Ovid) and the Cochrane Central Register of Controlled Trials (CENTRAL) to identify relevant studies. Included studies had their data extracted and both a quality assessment and statistical analysis were performed. Results The summary estimate of prehospital studies with video technology showed a statistically significant increase in first pass ETI success in favour of bougies (RR 1.15, CI 1.10–1.21, p < 0.0001). The summary estimates of prehospital studies without video technology and simulation studies with and without video technology showed no statistical difference between methods for first pass or overall ETI success. Some of the highest success rates were recorded by devices that incorporated video technology. Stylets lead to a shorter time to ETI while bougies were easier to use. Neither device was associated with a higher rate of ETI complications than the other. Conclusion Both tracheal tube introducers and stylets function as efficacious aids to intubation in the prehospital environment. Where video technology is available, bougies could offer a statistically significant advantage in terms of first pass ETI success. Where video technology is unavailable, a combination of clinical scenario, practitioner expertise and personal preference might ultimately guide the choice of device.

For perioperative mechanical ventilation under general anesthesia, modern respirators aim at combining the benefits of pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV) in modes typically named “volume-guaranteed” or “volume-targeted” pressure-controlled ventilation (PCV-VG). This systematic review and meta-analysis tested the hypothesis that PCV-VG modes of ventilation could be beneficial in terms of improved airway pressures (Ppeak, Pplateau, Pmean), dynamic compliance (Cdyn), or arterial blood gases (PaO2, PaCO2) in adults undergoing elective surgery under general anesthesia. Three major medical electronic databases were searched with predefined search strategies and publications were systematically evaluated according to the Cochrane Review Methods. Continuous variables were tested for mean differences using the inverse variance method and 95% confidence intervals (CI) were calculated. Based on the assumption that intervention effects across studies were not identical, a random effects model was chosen. Assessment for heterogeneity was performed with the χ2 test and the I2 statistic. As primary endpoints, Ppeak, Pplateau, Pmean, Cdyn, PaO2, and PaCO2 were evaluated. Of the 725 publications identified, 17 finally met eligibility criteria, with a total of 929 patients recruited. Under supine two-lung ventilation, PCV-VG resulted in significantly reduced Ppeak (15 studies) and Pplateau (9 studies) as well as higher Cdyn (9 studies), compared with VCV [random effects models; Ppeak: CI −3.26 to −1.47; p < 0.001; I2 = 82%; Pplateau: −3.12 to −0.12; p = 0.03; I2 = 90%; Cdyn: CI 3.42 to 8.65; p < 0.001; I2 = 90%]. For one-lung ventilation (8 studies), PCV-VG allowed for significantly lower Ppeak and higher PaO2 compared with VCV. In Trendelenburg position (5 studies), this effect was significant for Ppeak only. This systematic review and meta-analysis demonstrates that volume-targeting, pressure-controlled ventilation modes may provide benefits with respect to the improved airway dynamics in two- and one-lung ventilation, and improved oxygenation in one-lung ventilation in adults undergoing elective surgery.

Abstract Aim The ongoing Covid-19 pandemic has interrupted the surgical treatment of colorectal cancer (CRC). This systematic review will assess literature concerning the risk of delay of elective surgery for CRC patients, focusing on overall survival (OS) and disease-free survival (DFS). Method A systematic review was performed as per PRISMA guidelines (PROSPERO ID: CRD42020189158). Medline, EMBASE and Scopus were searched. Delay to elective surgery was defined as the period between CRC diagnosis and the day of surgery. Metanalyses of the outcome’s OS and DFS were conducted. Forest plots, funnel plots, and tests of heterogeneity were produced. An estimated Number Needed to Harm (NNH) was calculated for statistically significant pooled Hazard Ratios (HRs). Results Of 3753 articles identified, seven met the inclusion criteria. Encompassing 314560 patients, three of the seven studies showed that a delay to elective resection is associated with poorer OS or DFS. OS was assessed at a one-month delay, the HR for six datasets was 1.13 (95%CI 1.02-1.26, p = 0.020) and at three months the pooled HR for three datasets was 1.57 (95%CI 1.16-2.12, p = 0.004). Estimated NNHs for a delay at one month and three months were 35 and 10 respectively. Delay was non-significantly negatively associated with DFS on meta-analysis. Conclusions This review recommends that elective surgery for CRC patients is not postponed, as evidence suggests delays from diagnosis are associated with poorer outcomes. Focused research is essential so that patient groups can be prioritized based on risk factors for future pandemics.

Intravenous General Anesthesia

Abstract Postoperative cognitive dysfunction (POCD) has been increasingly recognized as a contributor to postoperative complications. A consensus-working group recommended that POCD should be distinguished between delayed cognitive recovery, i.e., evaluations up to 30 days postoperative, and neurocognitive disorder, i.e., assessments performed between 30 days and 12 months after surgery. Additionally, the choice of the anesthetic, either inhalational or total intravenous anesthesia (TIVA) and its effect on the incidence of POCD, has become a focus of research. Our primary objective was to search the literature and conduct a meta-analysis to verify whether the choice of general anesthesia may impact the incidence of POCD in the first 30 days postoperatively. As a secondary objective, a systematic review of the literature was conducted to estimate the effects of the anesthetic on POCD between 30 days and 12 months postoperative. For the primary objective, an initial review of 1,913 articles yielded 12 studies with a total of 3,639 individuals. For the secondary objective, five studies with a total of 751 patients were selected. In the first 30 days postoperative, the odds-ratio for POCD in TIVA group was 0.60 (95% CI = 0.40 - 0.91; p = 0.02), compared to the inhalational group. TIVA was associated with a lower incidence of POCD in the first 30 days postoperatively. Regarding the secondary objective, due to the small number of selected articles and its high heterogeneity, a metanalysis was not conducted. Giving the heterogeneity of criteria for POCD, future prospective studies with more robust designs should be performed to fully address this question.

Revascularization Surgery

BACKGROUND Patients undergoing lower limb revascularization surgery for peripheral artery disease (PAD) have a high-risk of perioperative morbidity and mortality and often have long hospital stays. Use of neuraxial or regional anesthesia instead of general anesthesia may represent one approach to improving outcomes and reducing resource use among these patients. OBJECTIVE To conduct a systematic review and meta-analysis to determine whether receipt of neuraxial or regional anesthesia instead of general anesthesia in adults undergoing lower limb revascularization surgery for PAD results in improved health outcomes and costs and a shorter length of hospitalization. METHODS We will search electronic bibliographic databases (MEDLINE, EMBASE, and the seven databases in Evidence-Based Medicine Reviews), review articles identified during the search, and included article bibliographies. We will include randomized and non-randomized studies comparing use of neuraxial or regional anesthesia instead of general anesthesia in adults undergoing lower limb revascularization surgery for PAD. Two investigators will independently evaluate risk of bias. The primary outcome will be short-term mortality (in-hospital or 30-day). Secondary outcomes will include longer-term mortality; major adverse cardiovascular, pulmonary, and renal events; delirium; deep vein thrombosis or pulmonary embolism; major adverse limb events; neuraxial or regional anesthesia-related complications; graft-related outcomes; length of operation and hospital stay; costs; and patient-reported or functional outcomes. We will calculate summary odds ratios and standardized mean differences using random-effects models. Heterogeneity will be explored using stratified meta-analyses and meta-regression. We will assess for publication bias using Begg’s and Egger’s tests and use the trim-and-fill method to estimate the potential influence of this bias on summary estimates. Finally, we will use Grading of Recommendations, Assessment, Development, and Evaluation methodology to make an overall rating of the quality of evidence in our effect estimates. RESULTS The protocol was registered in PROSPERO, the international register of systematic reviews. CONCLUSIONS This study will synthesize existing evidence regarding whether receipt of neuraxial or regional anesthesia instead of general anesthesia in adults undergoing lower limb revascularization surgery for PAD results in improved health outcomes, graft patency, and costs, and a shorter length of hospital stay. Study results will be used to inform practice and future research, including creation of a pilot and then multicenter randomized controlled trial. CLINICALTRIAL PROSPERO CRD42021237060.
