221711.pdf (Publisher’s version ) (Closed access)Our research group recently published a positive association between early postoperative pain and 30-day postoperative complications in a broad surgical population. To investigate whether heterogeneity of the population and surgical procedures influenced these results, we explored this association in a homogenous surgical population. A secondary analysis of the LEOPARD-2 (clinicaltrials.gov NCT02146417) and RELAX-1 study (NCT02838134) in laparoscopic donor nephrectomy patients (n = 160) was performed. Pain scores on the postanesthesia care unit and postoperative day (POD) 1 and 2 were compared between patients with infectious, noninfectious, and no complications 30 days after surgery. Patients who developed infectious complications had significantly higher pain scores on POD1 and 2 (6.7 ± 2.1 and 6.4 ± 2.8) than patients without complications (4.9 ± 2.2 and 4.1 ± 1.9), respectively (P = 0.006 and P = 0.000). Unacceptable pain (numeric rating scale [NRS] ≥ 6) on POD1 was reported by 72% of patients who developed infectious complications, compared to 38% with noninfectious complications and 30% without complications (P = 0.018). This difference was still present on POD2 at 67% with infectious complications, 21% with noninfectious, and 40% without complications (P = 0.000). Multiple regression analysis identified unacceptable pain (numeric rating scale ≥6) on POD2 as a significant predictor for 30-day infectious complications (odds ratio 6.09, P = 0.001). Results confirm the association between early postoperative pain and 30-day infectious complications in a separate, homogenous surgical population. Further clinical trials should focus on finetuning of postoperative analgesia to elucidate the effects on the endocrine and immune response, preserve immune homeostasis, and prevent postoperative infectious complications
Visualising improved peritoneal perfusion at lower intra-abdominal pressure by fluorescent imaging during laparoscopic surgery: A randomised controlled study

221721.pdf (Publisher’s version ) (Closed access)BACKGROUND: Laparoscopy is the gold standard for many surgical procedures and is embraced as minimally invasive surgery in the enhanced recovery after surgery programme. Lowering intra-abdominal pressure during laparoscopy may decrease the degree of surgical injury and further enhance patient outcomes. This study aims to assess the effect of low pressure pneumoperitoneum on peritoneal perfusion during laparoscopic surgery. MATERIALS AND METHODS: We performed a prospective randomized intervention study in 30 adults undergoing colorectal robot assisted laparoscopic surgery at a secondary care medical center in the Netherlands between June and December 2018. A 3 min video recording of the parietal peritoneum was made with the Da Vinci® Firefly mode following intravenous injection of 0.2 mg/kg indocyanine green at a pneumoperitoneum pressure of 8, 12 or 16 mmHg. Observers were blinded for the level of intra-abdominal pressure that was used. Fluorescent intensity in [-] over time was extracted from each video in MATLAB. Time to reach maximal fluorescent intensity (TMFI) and maximum fluorescent intensity (MFI) were compared among groups. The study was registered at clinicaltrials.gov (NCT03928171). RESULTS: Mean TMFI was shorter at low pressure (8 mmHg) than standard pressure (12 and 16 mmHg): 44 ± 12 versus 58 ± 18 s (p = 0.032), respectively. Mean MFI was higher at 8 mmHg than 12 and 16 mmHg (222 ± 25 versus 188 ± 54, p = 0.033). Regression analysis identified intra-abdominal pressure, mean arterial pressure and female gender as significant predictors of peritoneal perfusion. CONCLUSION: Low pressure pneumoperitoneum was associated with improved perfusion of the parietal peritoneum. Current available evidence supported feasibility and enhanced postoperative recovery. Future investigations should focus on optimizing factors that facilitate lower intra-abdominal pressure and explore effects on other clinically relevant patient outcomes such as anastomotic leakage and immune homeostasis
Deep neuromuscular block reduces the incidence of intra-operative complications during laparoscopic donor nephrectomy: a pooled analysis of randomized controlled trials
Study objective: To assess whether different intensities of intra-abdominal pressure and deep neuromuscular blockade influence the risk of intra-operative surgical complications during laparoscopic donor nephrectomy.Design: A pooled analysis of ten previously performed prospective randomized controlled trials.Setting: Laparoscopic donor nephrectomy performed in four academic hospitals in the Netherlands: Radboudumc, Leiden UMC, Erasmus MC Rotterdam, and Amsterdam UMC.Patients: Five hundred fifty-six patients undergoing a transperitoneal, fully laparoscopic donor nephrectomy enrolled in ten prospective, randomized controlled trials conducted in the Netherlands from 2001 to 2017.Interventions: Moderate (tetanic count of four > 1) versus deep (post-tetanic count 1-5) neuromuscular blockade and standard (>= 10 mmHg) versus low (= 2 occurred. Multiple logistic regression analyses showed standard intra-abdominal pressure (OR 0.318, 95% CI 0.118-0.862; p = 0.024) as a predictor of less intra-operative complications and moderate neuromuscular blockade (OR 3.518, 95% CI 1.244-9.948; p = 0.018) as a predictor of more intra-operative complications. Postoperative complications occurred in 31/556 (6.8%), without significant predictors in multiple logistic regression analyses.Conclusions: Our data indicate that the use of deep neuromuscular blockade could increase safety during laparoscopic donor nephrectomy. Future randomized clinical trials should be performed to confirm this and to pursue whether it also applies to other types of laparoscopic surgery.Perioperative Medicine: Efficacy, Safety and Outcome (Anesthesiology/Intensive Care
Low intra-abdominal pressure in laparoscopic surgery: a systematic review and meta-analysis.
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 (<10Â mmHg) with standard IAP (10Â 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 (<10Â 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
