Abstract
ABSTRACT Recent literature suggests that the withdrawal of remifentanil (RF) infusion can be associated with hyperalgesia in clinical and nonclinical settings. We performed a systematic review and a meta-analysis of randomized controlled trials with cross-over design, to assess the effect of discontinuing RF infusion on pain intensity and areas of hyperalgesia and allodynia in healthy volunteers. Nine studies were included. The intervention treatment consisted in RF infusion that was compared with placebo (saline solution). The primary outcome was pain intensity assessment at 30 ± 15 minutes after RF or placebo discontinuation, assessed by any pain scale and using any quantitative sensory testing. Moreover, postwithdrawal pain scores were compared with baseline scores in each treatment. Secondary outcomes included the areas (% of basal values) of hyperalgesia and allodynia. Subjects during RF treatment reported higher pain scores after discontinuation than during treatment with placebo [standardized mean difference (SMD): 0.50, 95% confidence interval (CI): 0.03-0.97; P = 0.04, I 2 = 71%]. A significant decrease in pain scores, compared with baseline values, was found in the placebo treatment (SMD: -0.87, 95% CI: -1.61 to -0.13; P = 0.02, I 2 = 87%), but not in the RF treatment (SMD: -0.28, 95% CI: -1.18 to 0.62; P = 0.54, I 2 = 91%). The area of hyperalgesia was larger after RF withdrawal (SMD: 0.55; 95% CI: 0.27-0.84; P = 0.001; I 2 = 0%). The area of allodynia did not vary between treatments. These findings suggest that the withdrawal of RF induces a mild but nonclinically relevant degree of hyperalgesia in HVs, likely linked to a reduced pain threshold.

[PMID: 38218762 PMCID: PMC10790271 DOI: 10.1186/s12871-023-02388-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 12/17/2023] [Indexed: 01/15/2024] Open
Abstract
BACKGROUND This meta-analysis aimed to explore the correlation between the different doses of remifentanil-based anaesthesia and postoperative pain in randomised trials. METHODS The electronic databases including PubMed, Cochrane, clinical trial registries, and Google Scholar were searched up to November 2022 for randomised controlled trials (RCTs) that assessed the dose dependent efficacy of remifentanil for postoperative pain intensity and hyperalgesia. RESULTS 31 studies involving 2019 patients were included for analysis. Compared with the high remifentanil dose administration, patients in low doses showed less postoperative pain intensity at 1-2 h (weighted mean differences (WMD): 0.60, 95% CI, 0.05 to 1.15), 3-8 h (WMD: 0.38, 95% CI, 0.00 to 0.75), 24 h (WMD: 0.26, 95% CI, 0.04 to 0.48) and 48 h (WMD: 0.32, 95% CI, 0.09 to 0.55). Remifentanil-free regimen failed to decrease the pain score at 24 h (WMD: 0.10, 95% CI, -0.10 to 0.30) and 48 h (WMD: 0.15, 95% CI, -0.22 to 0.52) in comparison with remifentanil-based anaesthesia. After excluding trials with high heterogeneity, the dose of the remifentanil regimen was closely correlated with the postoperative pain score (P=0.03). In addition, the dose of the remifentanil regimen was not associated with the incidence of postoperative nausea and vomiting (PONV) (P=0.37). CONCLUSIONS Our meta-analysis reveals that the low dose of remifentanil infusion is recommendable for general anaesthesia maintenance. No evidence suggests that remifentanil-free regimen has superiority in reducing postoperative pain. Moreover, remifentanil doesn't have a dose dependent effect in initiating PONV. TRIAL REGISTRATION The protocol of present study was registered with PROSPERO (CRD42022378360).

Abstract
The administration of analgesic drugs in elderly patients should take into account age-related physiological changes, loss of efficiency of homeostatic mechanisms, and pharmacological interactions with chronic therapies. Underestimation of pain in patients with impaired cognition is often linked to difficulties in pain assessment. In the preoperative phase, it is essential to assess the physical status, cognitive reserve, and previous chronic pain conditions to plan effective analgesia. Furthermore, an accurate pharmacological history of the patient must be collected to establish any possible interaction with the whole perioperative analgesic plan. The use of analgesic drugs with different mechanisms of action for pain relief in the intraoperative phase is a crucial step to achieve adequate postoperative pain control in older adults. The combined multimodal and opioid-sparing strategy is strongly recommended to reduce side effects. The use of various adjuvants is also preferable. Moreover, the implementation of non-pharmacological approaches may lead to faster recovery. High-quality postoperative analgesia in older patients can be achieved only with a collaborative interdisciplinary team. The aim of this review is to highlight the perioperative pain management strategies in the elderly with a special focus on intraoperative pharmacological interventions.

Abstract
Remifentanil-induced hyperalgesia (RIH) is a common and complicated issue in patients undergoing laparoscopic cholecystectomy (LC), which significantly reduces patient satisfaction. The present trial was designed to clarify the individual and combined effects of flurbiprofen-axetil and nalbuphine on remifentanil-induced hyperalgesia. This randomized double-blind clinical trial included 120 adult patients who underwent LC at The Second People's Hospital of Wuhu. The individuals were randomized into a flurbiprofen-axetil group (F group), nalbuphine group (N group), flurbiprofen-axetil combined with nalbuphine group (FN group) and saline group (S group). The four groups were given flurbiprofen-axetil (50 mg, iv.), nalbuphine (0.1 mg/kg, iv.), flurbiprofen-axetil (50 mg, iv.) combined with nalbuphine (0.1 mg/kg, iv.) or normal saline respectively prior to skin incision. The primary outcome was the postoperative mechanical pain thresholds at the inner forearm and peri-incisional area. The secondary outcomes were the visual analog scale (VAS) and Ramsay sedation scale at 0.5, 1, 4 and 24 h after surgery, and any other adverse events. The pain threshold of the medial forearm in the FN group did not differ from that in the F and N groups at 24 h after surgery (P=0.310 and P=0.910, respectively). However, the pain threshold around the incision in FN group was significantly lower than that in F and N groups 24 h after surgery (P=0.001). The VAS of the F group, N group and FN group were all significantly lower than that in the S group at 0.5, 1 and 24 h after surgery (P<0.001). No significant differences were observed in the incidence of adverse events between the four groups. Single flurbiprofen-axetil and single nalbuphine effectively prevented RIH 24 h after surgery in LC. The combination of the two analgesic drugs, with different mechanisms of action, was not superior to single therapy. The present study was registered with the Chinese Clinical Trial Registry (registration no. ChiCTR2100045347).

Abstract
INTRODUCTION Laparoscopic inguinal hernia repair has significantly reduced the incidence of postoperative acute and chronic pain compared to open repair, but it remains problematic. This study's purpose was to retrospectively identify predictive factors of acute pain after laparoscopic inguinal hernia repair. METHODS We reviewed the medical records of 193 patients. After excluding atypical cases and female patients, 156 patients were analysed. Factors affecting rescue analgesic requirements were investigated via multivariable logistic regression analysis. Independent variables included age, body mass index, analgesics used during surgery and surgical factors (unilateral/bilateral, primary/recurrent). The degree of postoperative pain and the hospital stay duration after surgery were also investigated. RESULTS Of the 156 patients, 40 (25.6%) required rescue analgesics. Patients under 60 years of age were about seven times more likely to need rescue analgesics than patients over 80 years of age. Primary surgery patients were about 5.5 times more likely to need rescue analgesics than recurrent surgery patients. The maximum verbal rating scale score was less than 3 in 89% of patients. All patients were discharged by two days postoperatively. CONCLUSION Laparoscopic inguinal hernia repair results in less postoperative acute pain. However, analgesia management should be considered prudently for younger patients and primary surgery patients.

Anesthesia Effect of Remifentanil Combined with Propofol in Laparoscopic Cholecystectomy and Its Impact on Postoperative Cognitive Recovery. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9147416.

Abstract
Objective To investigate the anesthesia effect of remifentanil combined with propofol for laparoscopic cholecystectomy and its impact on postoperative cognitive recovery. Methods A total of 120 patients who underwent laparoscopic cholecystectomy in our hospital from February 2019 to June 2021 were recruited and assigned into either control group or experimental group at a ratio of 1 : 1 via the random number table method. The patients in the control group were anesthetized with fentanyl combined with propofol, and the patients in the experimental group were anesthetized with remifentanil combined with propofol. The clinical basic indicators (extubation time, recovery time, breathing recovery time, and orientation recovery time), and observer's assessment of awareness/sedation (OAA/S) scores and complications were compared between the two groups. Results There was no significant difference in extubation time between the two groups (P > 0.05). The postoperative wake-up time, respiratory recovery time, and orientation recovery time of the experimental group were significantly better than those of the control group (P < 0.05). The OAA/S scores of the patients in the experimental group were significantly higher than those in the control group immediately after surgery, 1 h after surgery, and 3 h after surgery (P < 0.05). There was no significant difference in the OAA/S scores between the two groups on the 1st day after operation (P > 0.05). The incidence of complications in the experimental group was significantly lower than that in the control group (P < 0.05). Conclusion Remifentanil + propofol for laparoscopic cholecystectomy patients has a significant anesthesia effect. This strategy effectively shortens the extubation, awakening, respiratory recovery, orientation recovery time of patients, and OAA/S score, suggest a minor impact on the postoperative cognitive function and state of consciousness. It has a high safety profile and thus is worthy of clinical application.

Abstract
Microglia acts as a critical player in neuroinflammation and neuronal injury. Remifentanil (Rem) has been reported to exert anti-inflammatory activity in several types of diseases. However, the role of Rem in microglia-mediated neuroinflammation is unclear. The present study was designed to investigate the effects of Rem against lipopolysaccharide (LPS)-activated BV2 microglial and PC12 cell induced by activated BV2 microglia. Cell proliferative ability was assessed with cell counting kit-8 assay and cellular morphology was observed. ELISA assay was used to measure the expressions of PGE2 and inflammatory factors. The contents of p-NF-KB p65, p-IKKα/β, and COX2 were evaluated with the aid of western blot. The levels of NO and iNOS were assessed with Griess assay, qRT-PCR, and western blot. In addition, Tunel assay and western blot were performed to assess cell apoptosis. The data revealed that Rem alleviated BV2 microglial morphological injury induced by LPS. Furthermore, Rem suppressed inflammatory releases, iNOS, NO and PGE2 stimulated by LPS in activated BV2 cells. Moreover, Rem suppressed PC12 cell injury, the generations of inflammatory factors and cell apoptosis triggered by inflammatory mediators secreted from activated BV2 cells. These results suggest that Rem exhibited anti-neuroinflammatory activity in protecting PC12 cells against injury derived from LPS-stimulated BV2 microglia.

Abstract
BACKGROUND Acute and persistent pain after surgery is well described. However, no large-scale studies on immediate postoperative pain in the operating room (OR) exist, hindering potential areas of research to improve clinical outcomes. Thus, we aimed to describe the occurrence and severity of immediate postoperative pain in a large, unselected cohort. METHODS This was a prospective cohort study, encompassing all procedures in 31 public hospitals in the Danish Realm, during a 5-day period including the weekend. Data on procedures and anesthesia were collected and the main outcome was occurrence of moderate or severe pain in the OR. Secondary outcomes included pain, sedation and nausea in the OR or during the first 15 min in the postanesthesia care unit (PACU) including relevant risk factors. Descriptive and logistic regression statistics were used. RESULTS A total of 3675 procedures were included for analysis (87% inclusion rate). Moderate or severe pain occurred in 7.4% (95% CI 6.5% to 8.3%) of cases in the OR immediately after awakening, rising to 20.2% in the OR and/or PACU. Large intraprocedure and interprocedure variations occurred (0.0%-37.5%), and in 20% of cases with epidural-general anesthesia patients experienced moderate or severe pain. Independent risk factors were female sex, younger age, preoperative pain, daily opioid use and major surgical procedures. CONCLUSION Moderate or severe pain in the immediate postoperative phase occurred in 20% of all cases with procedure and anesthesiological technique variations, suggesting a need for identification of relevant procedure-specific risk factors and development of preventive treatments.

Association Between Intraoperative Remifentanil Dosage and Postoperative Opioid Consumption in Adolescent Idiopathic Spine Surgery: A Retrospective Cohort Study. Anesth Analg 2021; 133:984-990.

Abstract
BACKGROUND Adolescent idiopathic scoliosis (AIS) surgery is associated with significant postoperative pain. Remifentanil is a short-acting opioid that is often used as a component of total intravenous anesthesia. Remifentanil has been implicated in acute opioid tolerance and opioid-induced hyperalgesia, resulting in increased postoperative pain and opioid consumption. This retrospective study sought to investigate the relationship between the dose of intraoperative remifentanil and cumulative postoperative opioid consumption through 72 hours following surgery for pediatric AIS patients. METHODS We performed a retrospective chart review of adolescent patients undergoing posterior spine instrumentation under total intravenous general anesthesia at a single major pediatric center between January 2015 and October 2017. The relationship between intraoperative cumulative weight-adjusted remifentanil dose and logarithmic transformation of cumulative weight-adjusted opioid consumption through 72 hours following surgery was examined by regression analysis. A priori determined potential confounding variables were collected, including demographic data, perioperative analgesic agents (ie, ketamine, dexmedetomidine, and acetaminophen), surgical duration, vertebrae instrumented, and blood transfusion. Multivariable linear regression analysis was used to adjust for these possible confounding variables. RESULTS Eighty-nine patients met inclusion criteria, of which 78 had complete data for analysis. Univariable linear regression analysis revealed no association between remifentanil dose and opioid consumption through 72 hours following surgery (slope = 0.79 [95% confidence interval [CI], 0.61-0.98; R2 = 0.0039; P = .588]). After adjustment for possible confounding factors, no relationship between remifentanil dose (regression coefficient (coeff.) -0.08; 95% CI, -1.59 to 1.43; P = .912) and opioid consumption through 72 hours was found (slope =0.90 [95% CI, -0.65 to 2.46]; R2 = 0.1634). Similar results were obtained when the model was repeated for opioid consumption in postanesthesia care unit (PACU). CONCLUSIONS In this study examining adolescent patients undergoing surgery for idiopathic scoliosis, no association was found between the dose of intraoperative remifentanil and postoperative opioid consumption in the context of a propofol-based total intravenous anesthetic and multimodal analgesia. These results provide direction for future prospective controlled studies to further evaluate this relationship.

Abstract
Hospitalized coronavirus disease 2019 (COVID-19)-infected patients suffer from both physical impairments and mental stress. Respiratory insufficiency and cardiovascular disturbances require most of the intensive care interventions, but they are also accompanied by depressive conditions, sadness and fear of dying. Sedatives are mostly respiratory and cardiovascular depressants and do not provide resistance to the pro-inflammatory burst induced by the virus. Ketamine is a unique and safe drug that enables well-controlled sedation and anesthesia, attenuates depression and mitigates suicidal thoughts, without depressing respiratory or cardiovascular mechanics. This brief communication highlights the benefits potentially provided by ketamine to patients hospitalized for COVID-19 infection.
