Background Surgical injury stimulates the systemic inflammatory response. The magnitude of the postoperative systemic inflammatory response has been shown to be significantly associated with short and long-term outcomes following surgery of varying severity. Different anesthetic techniques for surgery may have an impact on the postoperative systemic inflammatory response and on the rate of the postoperative infective complications. The aim of the present systematic review was to examine the relationship between perioperative anesthesia, the postoperative systemic inflammatory response and postoperative infective complications in patients undergoing surgery. Methods This was carried out using PubMed and other established databases from 1987 up to March 2018. In particular, randomized controlled studies and systemic inflammation markers, interleukin 6 and C-reactive protein were examined. Results Overall, 60 controlled, randomized clinical trials were included in the review. The mean or median values of both interleukin 6 and C-reactive protein were taken for each study and the mean value was calculated for each anesthetic group at sampling points of 12–24 and 24–72 hours for interleukin 6 and C-reactive protein respectively. When taking the magnitude of surgery into account, TIVA using propofol was significantly associated with a reduction in particular C-reactive protein ( P = .04). However, there were no other specific anesthetic methods including general, regional and combined anesthetics that were associated with a reduction in either interleukin 6 or C-reactive protein. Conclusion There is some evidence that anesthetic regimens may reduce the magnitude of the postoperative systemic inflammatory response. However, the studies were heterogeneous and generally of low quality. Future, well conducted, adequately powered studies are required to clarify the effect of anesthesia on the postoperative systemic inflammatory response and infective complications.

Background/aimThe magnitude of the postoperative systemic inflammatory response (SIR) is now recognised to be associated with both short and long-term outcomes in patients undergoing surgery for colon cancer. During such surgery, it is unclear whether the anaesthetic regimens influence the magnitude of the postoperative SIR, independent of other factors. The aim of the present study was to examine the association between anaesthetic agents, clinicopathological characteristics and the magnitude of the postoperative SIR in patients undergoing elective surgery for colon cancer. MethodsPatients with colon cancer who underwent elective open or laparoscopic surgery between 2008 and 2016 (n = 409) were studied at a single center. The relationship between type of anaesthesia, surgical technique; open (n = 241) versus laparoscopic (n = 168) and clinicopathological characteristics was examined by using chi-square testing. The chi-square test was used to determine which anaesthetic group influences the POD 2 CRP for only patients undergoing elective open colon surgery. ResultsThe majority of patients were <75 years old, male, normal weight or obese, underwent open surgery and had regional anaesthesia, in particular an epidural approach. There was a

There are reports that the use of regional anesthesia (RA) may be associated with better perioperative surgical stress response in cancer patients compared with general anesthetics (GA). However, the role of anesthesia on the magnitude of the postoperative systemic inflammatory response (SIR) in colorectal cancer patients, within an enhanced recovery pathway (ERP), is not clear. The aim of the present study was to examine the effect of anesthesia, within an enhanced recovery pathway, on the magnitude of the postoperative SIR in patients undergoing elective surgery for colorectal cancer. Database of 507 patients who underwent elective open or laparoscopic colorectal cancer surgery between 2015 and 2019 at a single center was studied. The anesthetic technique used was categorized into either GA or GA + RA using a prospective proforma. The relationship between each anesthetic technique and perioperative clinicopathological characteristics was examined using binary logistic regression analysis. The majority of patients were male (54%), younger than 65 years (41%), either normal or overweight (64%), and were nonsmokers (47%). Also, the majority of patients underwent open surgery (60%) and received mainly general + regional anesthetic technique (80%). On univariate analysis, GA + RA was associated with a lower day 4 CRP (≤150/>150 mg/L) concentration. On day 4, postoperative CRP was associated with anesthetic technique [odds ratio (OR) 0.58; confidence interval (CI) 0.31–1.07; P = .086], age (OR 0.70; CI 0.50–0.98; P = .043), sex (OR 1.15; CI 0.95–2.52; P = .074), smoking (OR 1.57; CI 1.13–2.19; P = .006), preoperative mGPS (OR 1.55; CI 1.15–2.10; P = .004), and preoperative dexamethasone (OR 0.70; CI 0.47–1.03; P = .072). On multivariate analysis, day 4 postoperative CRP was independently associated with anesthetic technique (OR 0.56; CI 0.32–0.97; P = .039), age (OR 0.74; CI 0.55–0.99; P = .045), smoking (OR 1.58; CI 1.18–2.12; P = .002), preoperative mGPS (OR 1.41; CI 1.08–1.84; P = .012), and preoperative dexamethasone (OR 0.68; CI 0.50–0.92; P = .014). There was a modest but an independent association between RA and a lower magnitude of the postoperative SIR. Future work is warranted with multicenter RCT to precisely clarify the relationship between anesthesia and the magnitude of the postoperative SIR.

Background Direct oral anticoagulants (DOACs) are considered high-risk medications and used to prevent thromboembolic events and stroke. This study aimed to examine patients’ views and experiences of DOACs use and factors that can promote safety associated with DOACs. Methods In-depth interviews were conducted with adult patients who had been prescribed DOACs, identified and invited by local collaborators in three different tertiary care hospitals in Saudi Arabia. A topic guide developed based on was used to inform the interview. Data were analysed thematically. Results Data saturation was achieved by the ninth participants. Three major themes were identified: (1) factors affecting DOAC's safety from the patients view; (2) barriers to adherence to DOACs and (3) strategies to promote the safety of DOACs. Lack of knowledge of DOACs, using inappropriate sources of information, lack of communication with HCPs, difficulty in having access to DOACs and lack of monitoring were the main factors affecting the safe use of DOACs. Unavailability of the drugs and difficulty in timely getting to hospitals affected adherence. Patients acknowledged difficulties communicating with healthcare professionals, timely access to anticoagulation clinics and in obtaining their DOACs on time. Conclusions There is a need to develop and evaluate theory-based interventions to promote patient knowledge, understanding and shared decision-making to optimise DOACs use and improve their safety.
