[PMID: 38839084 DOI: 10.1136/rapm-2024-105277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 05/15/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND Increasing evidence supports a positive relationship between the intensity of early postoperative pain, and the risk of 30-day postoperative complications. Higher pain levels may hamper recovery and contribute to immunosuppression after surgery. This leaves patients at risk of postoperative complications. METHODS One thousand patients who underwent major abdominal surgery (cytoreductive surgery and hyperthermic intraperitoneal chemotherapy, esophageal, liver, or pancreas surgery) at the Radboud university medical center were randomly selected from eligible patients between 2014 and 2020. Pain scores on day 1, the independent variable of interest, were extracted from the electronic patient files. Outcome measures were 30-day postoperative complications (infectious, non-infectious, total complications and classification according to Clavien-Dindo). RESULTS Seven hundred ninety complications occurred in 572 patients within 30 days after surgery, of which 289 (36.7%) were of infectious origin, and 501 (63.4%) complications were non-infectious. The mean duration from the end of surgery to the occurrence of infectious complications was 6.5 days (SD 5.6) and 4.1 days (SD 4.7) for non-infectious complications (p<0.001). Logistic regression analysis revealed that pain scores on postoperative day 1 (POD1) were significantly positively associated with 30-day total complications after surgery (OR=1.132, 95% CI (1.076 to 1.190)), Clavien-Dindo classification (OR=1.131, 95% CI (1.071 to 1.193)), infectious complications (OR=1.126, 95% CI (1.059 to 1.196)), and non-infectious complications (OR=1.079, 95% CI (1.022 to 1.140)). CONCLUSIONS After major abdominal surgery, higher postoperative pain scores on day 1 are associated with an increased risk of 30-day postoperative complications. Further studies should pursue whether optimization of perioperative analgesia can improve immune homeostasis, reduce complications after surgery and enhance postoperative recovery.

The role of surgical tissue injury and intraoperative sympathetic activation in postoperative immunosuppression after breast-conserving surgery versus mastectomy: a prospective observational study. Breast Cancer Res 2024; 26:42. [PMID: 38468349 PMCID: PMC10926636 DOI: 10.1186/s13058-024-01801-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 02/28/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Breast cancer is the second most common cause of death from cancer in women worldwide. Counterintuitively, large population-based retrospective trials report better survival after breast-conserving surgery (BCS) compared to mastectomy, corrected for tumour- and patient variables. More extensive surgical tissue injury and activation of the sympathetic nervous system by nociceptive stimuli are associated with immune suppression. We hypothesized that mastectomy causes a higher expression of plasma damage associated molecular patterns (DAMPs) and more intraoperative sympathetic activation which induce postoperative immune dysregulation. Immune suppression can lead to postoperative complications and affect tumour-free survival. METHODS In this prospective observational study, plasma DAMPs (HMGB1, HSP70, S100A8/A9 and S100A12), intraoperative sympathetic activation (Nociception Level (NOL) index from 0 to 100), and postoperative immune function (plasma cytokine concentrations and ex vivo cytokine production capacity) were compared in patients undergoing elective BCS (n = 20) versus mastectomy (n = 20). RESULTS Ex vivo cytokine production capacity of TNF, IL-6 and IL-1β was nearly absent in both groups one hour after surgery. Levels appeared recovered on postoperative day 3 (POD3), with significantly higher ex vivo production capacity of IL-1β after BCS (p = .041) compared to mastectomy. Plasma concentration of IL-6 was higher one hour after mastectomy (p = .045). Concentrations of plasma alarmins S100A8/A9 and S100A12 were significantly higher on POD3 after mastectomy (p = .003 and p = .041, respectively). Regression analysis showed a significantly lower percentage of NOL measurements ≤ 8 (absence of nociception) during mastectomy when corrected for norepinephrine equivalents (36% versus 45% respectively, p = .038). Percentage of NOL measurements ≤ 8 of all patients correlated with ex vivo cytokine production capacity of IL-1β and TNF on POD3 (r = .408; p = .011 and r = .500; p = .001, respectively). CONCLUSIONS This pilot study revealed substantial early postoperative immune suppression after BCS and mastectomy that appears to recover in the following days. Differences between BCS and mastectomy in release of DAMPs and intraoperative sympathetic activation could affect postoperative immune homeostasis and thereby contribute to the better survival reported after BCS in previous large population-based retrospective trials. These results endorse further exploration of (1) S100 alarmins as potential therapeutic targets in breast cancer surgery and (2) suppression of intraoperative sympathetic activation to substantiate the observed association with postoperative immune dysregulation.

Deep versus moderate neuromuscular blockade during total hip arthroplasty to improve postoperative quality of recovery and immune function: protocol for a randomised controlled study. BMJ Open 2023; 13:e073537. [PMID: 37640469 PMCID: PMC10462972 DOI: 10.1136/bmjopen-2023-073537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 08/16/2023] [Indexed: 08/31/2023] Open
Abstract
INTRODUCTION There is accumulating evidence that deep neuromuscular blockade (NMB) improves intraoperative surgical conditions during laparoscopic surgery. Studies investigating the effects of deep NMB in open surgery are scarce. In theory, by limiting surgical damage through deeper muscle relaxation, postoperative inflammation and concomitant immune suppression can be reduced. Therefore, this study will investigate the effects of deep NMB during total hip arthroplasty, which demands a relatively large exposure of the hip joint through and in between muscles. METHODS AND ANALYSIS This study is a monocentre blinded randomised controlled trial in 100 patients undergoing total hip arthroplasty under general anaesthesia. Patients will be randomised in a 1:1 fashion to an intervention group of intraoperative deep NMB (a post-tetanic count of 1-2) or a control group receiving moderate NMB (a train-of-four count of 1-2). NMB will be achieved by continuous or bolus administration of rocuronium, respectively. The primary endpoint is the quality of recovery at postoperative day 1 measured by the Quality of Recovery-40 Questionnaire, analysed by Analysis of Variance. The secondary endpoint is postoperative innate immune function, measured by ex vivo production capacity of tumour necrosis factor and interleukin-1β on endotoxin stimulation of whole blood. ETHICS AND DISSEMINATION Ethical approval for this study was granted by the Medical Ethics Committee 'METC Oost-Nederland' (reference number 2022-15754). Informed consent will be obtained prior to study participation. Study results will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBERS ClinicalTrials.gov Registry (NCT05562999) and EudraCT Registry (2022-002451-19).

Low intra-abdominal pressure in laparoscopic surgery: a systematic review and meta-analysis. Int J Surg 2023; 109:1400-1411. [PMID: 37026807 PMCID: PMC10389627 DOI: 10.1097/js9.0000000000000289] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 02/03/2023] [Indexed: 04/08/2023]
Abstract
BACKGROUND Guidelines do not provide clear recommendations with regard to the use of low intra-abdominal pressure (IAP) during laparoscopic surgery. The aim of this meta-analysis is to assess the influence of low versus standard IAP during laparoscopic surgery on the key-outcomes in perioperative medicine as defined by the StEP-COMPAC consensus group. MATERIALS AND METHODS We searched the Cochrane Library, PubMed, and EMBASE for randomized controlled trials comparing low IAP (<10 mmHg) with standard IAP (10 mmHg or higher) during laparoscopic surgery without time, language, or blinding restrictions. According to the PRISMA guidelines, two review authors independently identified trials and extracted data. Risk ratio (RR), and mean difference (MD), with 95% CIs were calculated using random-effects models with RevMan5. Main outcomes were based on StEP-COMPAC recommendations, and included postoperative complications, postoperative pain, postoperative nausea and vomiting (PONV) scores, and length of hospital stay. RESULTS Eighty-five studies in a wide range of laparoscopic procedures (7349 patients) were included in this meta-analysis. The available evidence indicates that the use of low IAP (<10 mmHg) leads to a lower incidence of mild (Clavien-Dindo grade 1-2) postoperative complications (RR=0.68, 95% CI: 0.53-0.86), lower pain scores (MD=-0.68, 95% CI: -0.82 to 0.54) and PONV incidence (RR=0.67, 95% CI: 0.51-0.88), and a reduced length of hospital stay (MD=-0.29, 95% CI: -0.46 to 0.11). Low IAP did not increase the risk of intraoperative complications (RR=1.15, 95% CI: 0.77-1.73). CONCLUSIONS Given the established safety and the reduced incidence of mild postoperative complications, lower pain scores, reduced incidence of PONV, and shorter length of stay, the available evidence supports a moderate to strong recommendation (1a level of evidence) in favor of low IAP during laparoscopic surgery.

Abstract
While U.S. opioid prescribing has decreased 38% in the past decade, opioid deaths have increased 300%. This opioid paradox is poorly recognized. Current approaches to opioid management are not working, and new approaches are needed. This article reviews the outcomes and shortcomings of recent U.S. opioid policies and strategies that focus primarily or exclusively on reducing or eliminating opioid prescribing. It introduces concepts of a prescription opioid ecosystem and opioid pool, and it discusses how the pool can be influenced by supply-side, demand-side, and opioid returns factors. It illuminates pressing policy needs for an opioid ecosystem that enables proper opioid stewardship, identifies associated responsibilities, and emphasizes the necessity of making opioid returns as easy and common as opioid prescribing, in order to minimize the size of the opioid pool available for potential diversion, misuse, overdose, and death. Approaches are applicable to opioid prescribing in general, and to opioid prescribing after surgery.

Abstract
The quadratus lumborum block is a novel truncal block where local anaesthetic is injected adjacent to the quadratus lumborum muscle. It is used for caesarean sections, hip arthroplasty, gynecologic surgery, colectomy, and recently nephrectomy. To date, there are no reviews that outline the efficacy and performance of the quadratus lumborum blocks in patients receiving laparoscopic nephrectomy. The objective of this project was to outline the current available data from both clinical trials along with case series and reports regarding the methods and utility of quadratus lumborum blocks for analgesia in patients receiving nephrectomy. For this literature review, we searched Pubmed, Embase, and Web of Science from their inception until 5/31/2020. Our search terms were as follows: “(nephrectomy OR laparoscopic nephrectomy) AND (QL block OR Quadratus Lumborum block OR QL OR TQL OR Thoracolumbar fascia block).” We analyzed all relevant clinical trials for quality using the Jadad scale. Our search yielded a total of 30 articles, 23 of which we ultimately reviewed for this manuscript. The qualitative sum of these data show that patients receiving quadratus lumborum block for nephrectomies have reduced opioid requirements, reduced pain scores, and improved side-effects relative to other analgesic modalities like epidurals. Based on these findings, we conclude that the quadratus lumborum block is a useful analgesic for patients undergoing nephrectomy.
