RESUMO
INTRODUCTION: Selective posterior rhizotomy (SPR) is a preferred procedure for relieving spastic children with cerebral palsy, but it is associated with severe pain and significant emergence agitation (EA). The thoracolumbar interfascial plane (TLIP) block provides an effective blockade to the dorsal branch of the spinal nerve. We hypothesise that the TLIP block may be an effective tool to alleviate EA and postoperative pain scores in children with cerebral palsy undergoing SPR. METHODS AND ANALYSIS: This study is a single-centre, randomised, parallel-controlled trial being conducted in Beijing, China. A total of 50 paediatric patients with cerebral palsy scheduled for SPR are randomised in a 1:1 ratio to receive bilateral TLIP block with 0.2% ropivacaine 0.5 mL/kg or control. Patients in the TLIP group receive general anaesthesia combined with TLIP block, while patients in the control group receive only general anaesthesia, without a TLIP block. The primary outcome is the Paediatric Anaesthesia Emergence Delirium Score. The secondary outcomes are the incidence of EA, the Wong-Baker Faces Pain-rating Scale, the perioperative haemodynamics, the intraoperative remifentanil and propofol dosage, the extubation time and recovery time, and adverse reactions. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee of Dongzhimen Hospital, Beijing University of Chinese Medicine on 21 September 2023 (2023DZMEC-379-02). Written informed consent is obtained from the legal guardian of each patient. The results of this study will be published in peer-reviewed international journals. TRIAL REGISTRATION NUMBER: ChiCTR2300076397.

BACKGROUND: Managing postoperative pain effectively with an opioid-free regimen following laparoscopic surgery (LS) remains a significant challenge. Intraperitoneal instillation of ropivacaine has been explored for its potential to reduce acute postoperative pain, but its efficacy and safety are still under debate. This study aimed to evaluate the efficacy and safety of intraperitoneal instillation of ropivacaine for acute pain management following laparoscopic digestive surgery. METHODS: We used PRISMA 2020 and a measurement tool to assess systematic reviews 2 guidelines to conduct this review. The random-effects model was adopted using Review Manager Version 5.4 for pooled estimates. RESULTS: We retained 24 eligible RCTs involving 1705 patients (862 patients in the intraperitoneal instillation group and 843 patients in the control group). The intraperitoneal instillation group reduced total opioid consumption during the first 24 hours postoperatively (MDâ =â -21.93 95% CI [-27.64, -16.23], Pâ <â .01), decreased pain scores at different time (4 hours, 8 hours, 12 hours and 24 hours), shorter the hospital stay (MDâ =â -0.20 95% CI [-0.36, -0.05], Pâ <â .01), reduced the postoperative shoulder pain (MDâ =â 0.18 95% CI [0.07, 0.44], Pâ <â .01), and decreased postoperative nausea and vomiting (MDâ =â 0.47 95% CI [0.29, 0.77], Pâ <â .01). CONCLUSION: Intraperitoneal instillation of ropivacaine appears to be an effective component of multimodal pain management strategies following laparoscopic digestive surgery, significantly reducing opioid consumption and improving postoperative recovery markers. Despite these promising results, additional high-quality trials are needed to confirm the efficacy and safety of this approach. REGISTRATION: The registration number at PROSPERO was CRD42021279238.

BACKGROUND: Combining hydromorphone with ropivacaine in ultrasound-guided erector spinae plane blocks enhances postoperative analgesia and reduces interleukin-6 expression in breast surgery patients. METHODS: In this study, breast cancer patients undergoing modified radical mastectomy were randomized into 3 groups for anesthesia (30 patients in each group): standard general (group C), Erector Spinae Plane Block (ESPB) with ropivacaine (group R), and ESPB with ropivacaine plus hydromorphone (group HR). Diagnosis: Breast cancer patients. Postsurgery, pain levels, IL-6, anesthetic doses, additional analgesia needs, and recovery milestones were compared to evaluate the efficacy of the ESPB enhancements. RESULTS: The 3 groups were not significantly different in baseline characteristics, operation time, number of cases with postoperative nausea, and serum IL-6 concentrations at T1 (the time of being returned to the ward after surgery). At T2 (at 6:00 in the next morning after surgery), the serum IL-6 concentration in group HR was significantly lower than that in groups R and C (Pâ <â .05); the intraoperative doses of remifentanil, sufentanil, and propofol were significantly lower in groups HR and R than those in group C (Pâ <â .05); Groups HR and R had significantly lower visual analog scale scores at T3 (4 hours postoperatively), T4 (12 hours postoperatively), and T5 (24 hours postoperatively) than those in group C (Pâ <â .05); the proportions of patients receiving postoperative remedial analgesia were significantly lower in groups HR and R than in group C (Pâ <â .05); groups HR and R had significantly lower proportions of patients with postoperative nausea than group C (Pâ <â .05); the time to the first anal exhaust and the time to the first ambulation after surgery were significantly shorter in groups HR and R than those in group C (Pâ <â .05). CONCLUSION: Hydromorphone combined with ropivacaine for ESPB achieved a greater postoperative analgesic effect for patients receiving MRM under general anesthesia. The combined analgesia caused fewer adverse reactions and inhibited the expression level of the inflammatory factor IL-6 more effectively, thereby facilitating postoperative recovery. ESPB using hydromorphone with ropivacaine improved pain control post-MRM, reduced adverse effects, and more effectively suppressed IL-6, enhancing recovery.

Purpose: To compare the impact of erector spinae plane block (ESPB) and paravertebral block (PVB) on the quality of postoperative recovery (QoR) of patients following laparoscopic sleeve gastrectomy (LSG). Methods: A total of 110 patients who underwent elective LSG under general anesthesia were randomly assigned to receive either ultrasound-guided bilateral ESPB or PVB at T8 levels. Before anesthesia induction, 40 mL of 0.33% ropivacaine was administered. The primary outcome was the QoR-15 score at 24 hours postoperatively. Results: At 24 hours postoperatively, the QoR-15 score was comparable between the ESPB and PVB groups (131 (112-140) vs. 124 (111-142.5), P = 0.525). Consistently, there was no significant difference in QoR-15 scores at 48 hours postoperatively, numerical rating scale (NRS) pain scores at any postoperative time points, time to first ambulation, time to first anal exhaust, postoperative cumulative oxycodone consumption, and incidence of postoperative nausea and vomiting (PONV) between the two groups (all P > 0.05). No nerve block-related complications were observed in either group. Conclusion: In patients undergoing LSG, preoperative bilateral ultrasound-guided ESPB yields comparable postoperative recovery to preoperative bilateral ultrasound-guided PVB.

Failure of sub-arachnoid block (SAB), due to resistance to bupivacaine after a recent scorpion sting can lead to multiple block attempts and subsequent conversion to general anaesthesia. We report this case series of 10 patients with successful SAB with newly launched 0.75% hyperbaric ropivacaine, in patients with recent scorpion sting. Thus, intrathecal hyperbaric ropivacaine may be considered as the local anaesthetic agent of choice in patients with scorpion sting to prevent failure of SAB.

BACKGROUND: In this study, we analyzed whether scalp nerve block with ropivacaine can improve the quality of rehabilitation in patients after meningioma resection. METHODS: We included 150 patients who were undergoing craniotomy in our hospital and categorized them into 2 groups - observation group (patients received an additional regional scalp nerve block anesthesia) and control group (patients underwent intravenous general anesthesia for surgery), using the random number table method approach (75 patients in each group). The main indicator of the study was the Karnofsky Performance Scale scores of patients at 3 days postoperatively, and the secondary indicator was the anesthesia satisfaction scores of patients after awakening from anesthesia. The application value of different anesthesia modes was studied and compared in the 2 groups. RESULTS: Patients in the observation group showed better anesthesia effects than those in the control group, with significantly higher Karnofsky Performance Scale scores at 3 days postoperatively (75.02 vs 66.43, Pâ <â .05) and anesthesia satisfaction scores. Compared with patients in the control group, patients in the observation group had lower pain degrees at different times after the surgery, markedly lower dose of propofol and remifentanil for anesthesia, and lower incidence of adverse reactions and postoperative complications. In addition, the satisfaction score of the patients and their families for the treatment was higher and the results of all the indicators were better in the observation group than in the control group, with statistically significant differences (Pâ <â .05). CONCLUSION: Scalp nerve block with ropivacaine significantly improves the quality of short-term postoperative rehabilitation in patients undergoing elective craniotomy for meningioma resection. This is presumably related to the improvements in intraoperative hemodynamics, relief from postoperative pain, and reduction in postoperative nausea and vomiting.

OBJECTIVES: A single nerve block provides excellent analgesia in a short time, but rebound pain after the nerve block dissipates has attracted researchers' attention. The aim of this study was to evaluate the effect of perineural dexamethasone on rebound pain after sciatic nerve block and femoral nerve block in patients undergoing unicompartmental knee arthroplasty (UKA). METHODS: In a double-blinded fashion, we recruited 72 patients undergoing UKA, each of whom received sciatic and femoral nerve block. Patients were randomly assigned to 2 groups (n=36): X (ropivacaine only) and D (ropivacaine combined with dexamethasone). The primary outcome was the incidence of rebound pain. The secondary outcomes were rebound pain score, the duration of rebound pain, the duration of nerve block, pain score, sufentanil consumption and rescue analgesic, patient-controlled intravenous analgesia, distance walked, sleep quality score, C-reactive protein levels, and adverse effects. RESULTS: Compared with group X, the incidence of rebound pain in group D was higher, the rebound pain score was higher and the duration of the nerve block was prolonged ( P <0.05). At 12, 16, and 20 hours postoperatively, the pain scores at rest in group D were lower. At 32 and 36 hours postoperatively, the pain scores at rest in group D were higher ( P <0.05). Furthermore, patients in group D had lower levels of C-reactive protein after surgery ( P <0.05). DISCUSSION: The addition of dexmedetomidine to ropivacaine for UKA effectively prolonged the duration of nerve block and decreased C-reactive protein levels, but increased the incidence of rebound pain and rebound pain score, and had no beneficial effects on the postoperative analgesia.

BACKGROUND: Ropivacaine, a local anesthetic, exhibits anti-tumor effects in various cancer types. However, its specific functions and the molecular mechanisms involved in breast cancer cell stemness remain elusive. METHODS: The effects of ropivacaine on breast cancer stemness were investigated by in vitro and in vivo assays (i.e., FACs, MTT assay, mammosphere formation assay, transwell assays, western blot, and xenograft model). RNA-seq, bioinformatics analysis, Western blot, Luciferase reporter assay, and CHIP assay were used to explore the mechanistic roles of ropivacaine subsequently. RESULTS: Our study showed that ropivacaine remarkably suppressed stem cells-like properties of breast cancer cells both in vitro and in vivo. RNA-seq analysis identified GGT1 as the downstream target gene responding to ropivacaine. High GGT1 levels are positively associated with a poor prognosis in breast cancer. Ropivacaine inhibited GGT1 expression by interacting with the catalytic domain of AKT1 directly to impair its kinase activity with resultant inactivation of NF-κB. Interestingly, NF-κB can bind to the promoter region of GGT1. KEGG and GSEA analysis indicated silence of GGT1 inhibited activation of NF-κB signaling pathway. Depletion of GGT1 diminished stem phenotypes of breast cancer cells, indicating the formation of NF-κB /AKT1/GGT1/NF-κB positive feedback loop in the regulation of ropivacaine-repressed stemness in breast cancer cells. CONCLUSION: Our finding revealed that local anesthetic ropivacaine attenuated breast cancer stemness through AKT1/GGT1/NF-κB signaling pathway, suggesting the potential clinical value of ropivacaine in breast cancer treatment.

Background: Local infiltration analgesia (LIA) provides postoperative analgesia for total knee arthroplasty (TKA). The purpose of this study was to evaluate the analgesic effect of a cocktail of ropivacaine, morphine, and Diprospan for TKA. Methods: A total of 100 patients from September 2018 to February 2019 were randomized into 2 groups. Group A (control group, 50 patients) received LIA of ropivacaine alone (80 ml, 0.25% ropivacaine). Group B (LIA group, 50 patients) received an LIA cocktail of ropivacaine, morphine, and Diprospan (80 ml, 0.25% ropivacaine, 0.125 mg/ml morphine, and 62.5 µg/ml compound betamethasone). The primary outcomes were the levels of inflammatory markers C-reactive protein (CRP) and interleukin-6 (IL-6), pain visual analog scale (VAS) scores, opioid consumption, range of motion (ROM), functional tests, and sleeping quality. The secondary outcomes were adverse events, satisfaction rates, HSS scores, and SF-12 scores. The longest follow-up was 2 years. Results: The two groups showed no differences in terms of characteristics (P > 0.05). Group B had lower resting VAS pain scores (1.54 ± 0.60, 95% CI = 1.37 to 1.70 vs. 2.00 ± 0.63, 95% CI = 2.05 to 2.34) and active VAS pain scores (2.64 ± 0.62, 95% CI = 2.46 to 2.81 vs. 3.16 ± 0.75, 95% CI = 2.95 to 3.36) within 48 h postoperatively than Group A (P < 0.001), while none of the pain differences exceeded the minimal clinically important difference (MCID). Group B had significantly lower CRP levels (59.49 ± 13.01, 95% CI = 55.88 to 63.09 vs. 65.95 ± 14.41, 95% CI = 61.95 to 69.94) and IL-6 levels (44.11 ± 13.67, 95% CI = 40.32 to 47.89 vs. 60.72 ± 15.49, 95% CI = 56.42 to 65.01), lower opioid consumption (7.60 ± 11.10, 95% CI = 4.52 to 10.67 vs. 13.80 ± 14.68, 95% CI = 9.73 to 17.86), better ROM (110.20 ± 10.46, 95% CI = 107.30 to 113.09 vs. 105.30 ± 10.02, 95% CI = 102.52 to 108.07), better sleep quality (3.40 ± 1.03, 95% CI = 3.11 to 3.68 vs. 4.20 ± 1.06, 95% CI = 3.90 to 4.49), and higher satisfaction rates than Group A within 48 h postoperatively (P < 0.05). Adverse events, HSS scores, and SF-12 scores were not significantly different within 2 years postoperatively. Conclusions: A cocktail of ropivacaine, morphine, and Diprospan prolongs the analgesic effect up to 48 h postoperatively. Although the small statistical benefit may not result in MCID, the LIA cocktail still reduces opioid consumption, results in better sleeping quality and faster rehabilitation, and does not increase adverse events. Therefore, cocktails of ropivacaine, morphine, and Diprospan have good application value for pain control in TKA. This trial is registered with ChiCTR1800018372.

OBJECTIVE: Reconstructive surgery of the anterior cruciate ligament (ACL) is quite common, previous studies have documented that adequate pain control in the early phases of the postoperative period translates into early mobility and a rapid start of rehabilitation. Therefore, the search for new strategies for postoperative pain control is justified. The aim of this study was to compare intra-articular to the epidural administration of ropivacaine and midazolam as postoperative analgesia after arthroscopic ACL reconstruction with hamstring autograft (HA). MATERIAL AND METHODS: Double-blinded, prospective randomized clinical trial included 108 consecutive patients aged from 18 to 50 years that had undergone arthroscopic ACL reconstruction with HA. The patients were randomly assigned to 2 groups. The first group received intraarticular ropivacaine and midazolam. The second group received epidural ropivacaine and midazolam. The need for rescue analgesia, the postoperative pain experienced, side effects and complications of the analgesic drugs were evaluated. RESULTS: The intra-articular group received statistically significantly higher mean doses of rescue analgesia on the first two days (2.8 â± â1.0 vs. 1.3 â± â0.6 in the epidural group; p â= â0.001). Visual Analogue Scale scores at flexion were statistically significantly higher in the intra-articular group over the entire study period. The intra-articular group also reported a statistically significantly lower range-of-motion 87 â± â15 vs. 102 â± â11 in the epidural group (p â= â0.001). CONCLUSIONS: Epidural administration of ropivacaine combined with midazolam in patients undergoing primary ACL reconstruction with HA was clinically and significantly better relative to rescue analgesia and the intensity of pain in the first 48 postoperative hours when compared to intraarticular administration. There was no difference in terms of adverse effects and complications.

OBJECTIVE: To evaluate the perioperative analgesic effect of the unilateral lumbar erector spinae plane block (ESPBL) in dogs undergoing hemilaminectomy. STUDY DESIGN: Randomized, blinded clinical study. ANIMALS: A total of 30 client-owned dogs undergoing thoracolumbar or lumbar hemilaminectomy for intervertebral disc extrusion (IVDE). METHODS: Dogs were randomly assigned to receive a unilateral ESPBL, performed either with 0.4 mL kg-1 ropivacaine 0.5% [group ROPI (n = 15)] or with saline solution [CNT group (n = 15)]. Dogs were premedicated intravenously (IV) with acepromazine 5 µg kg-1 and methadone 0.2 mg kg-1, general anaesthesia was induced by administering IV midazolam 0.2 mg kg-1 and propofol to effect and maintained with isoflurane. Fentanyl was administered as rescue analgesia. Bradycardia [heart rate (HR) < 60 beats minute-1] with hypotension was treated with atropine IV. The Short-Form of the Glasgow Composite Pain Scale was used pre- and postoperatively at 1, 2, 4, 8, 12, 16, 20 and 24 hours after extubation, and methadone 0.2 mg kg-1 was administered IV when pain score was ≥ 5/20. HR and end-tidal concentration of isoflurane (Fe'Iso) were compared between groups with anova combined with a Dunnet's post hoc test. Time to the first rescue methadone and total dose of fentanyl (FENtot, µg kg-1 hour-1) and methadone (METtot, mg kg-1) in the first 24 postoperative hours were compared using unpaired Student's t test. Postoperative pain scores were compared with the Mann-Whitney test and atropine administration with a Fisher's exact test; p < 0.05. RESULTS: HR, Fe'Iso, FENtot, METtot and atropine administration were significantly lower in group ROPI compared to CNT. Postoperative analgesic effect was significantly longer, and pain scores were significantly lower in group ROPI for all time points. CONCLUSIONS AND CLINICAL RELEVANCE: Unilateral ESPBL with ropivacaine reduced perioperative opioid consumption and the occurrence of bradycardia in dogs undergoing hemilaminectomy.

OBJECTIVES: The aim of the study was to compare, in patients undergoing minor gynecological laparoscopic procedures, the effects of ultrasound (US)-guided transversus abdominis plane (TAP) + rectus sheath (RS) block versus no TAP/RS block in terms of post-surgical pain control using the numeric pain rating scale (NRS) and the degree of patient satisfaction, according to the main goals of Early Recovery After Surgery (ERAS) programs. The primary outcome is to value the postoperative abdominal pain using NRS in both groups. Secondary outcomes are to evaluate blood values, presence of postoperative nausea and vomiting (PONV), postoperative ileus, level of patient expected satisfaction, time of discharge, length of stay (LOS), and the amounts of additional analgesics required. DESIGN: In this prospective randomized controlled trial, patients were randomly assigned to loco-regional anesthesia (LRA) group, who received TAP and RS block under US guidance, or no loco-regional anesthesia (N-LRA) group. Enrolled patients were randomized 1:1 to either receive bilateral TAP/RS block with ropivacaine or sham treatment (patches were applied on the abdominal wall of the patients under general anesthesia). PARTICIPANTS: All patients aged between 18 and 75 years, with ASA (American Society of Anesthesiologists) physical status 1-2, undergoing laparoscopic minor gynecological surgery, were enrolled. SETTING: The study was conducted to the University of Campus Bio-Medico Hospital of Rome. METHODS: Half an hour before surgery, all patients received gabapentin 300 mg per os. Once the patient underwent general anesthesia, US-guided bilateral TAP/RS block was performed by the anesthesiology team, while the uterine manipulator was positioned by a gynecology resident (not involved in the study). In the operative room, all patients received the same standardized anesthetic regimen. Postoperative abdominal pain was assessed at rest, after palpation, during movement, and after a cough by evaluating the patient at 6, 12, 18, 24, 36, 48, and 72 h after surgery, using the NRS from 0 to 10 in both groups. The amount of drug used for analgesia in the first 48 h after surgery was recorded. Moreover, hemoglobin, white blood cells, and c-reactive protein levels were recorded at 24, 48, and 72 h. The presence of PONV and the postoperative ileus was recorded throughout convalescence. The expected level of patient satisfaction at discharge and finally the LOS were assessed. LIMITATIONS: The major weakness of this study is that 60 mL of 0.5% ropivacaine was administered to each patient, without considering weight differences, yet contemporary literature rarely suggests volume/dose titration in fascial blocks. RESULTS: A total of 104 women, undergoing gynecological minor laparoscopic surgery, were enrolled and assigned to LRA group (53 pts) and N-LRA group (51 pts). Postoperative pain was significantly reduced in patients who received TAP/RS block. A reduction in the intake of non-steroidal anti-inflammatory drugs after surgery was registered in LRA group (p < 0.01). Moreover, a significant reduction of LOS (45.97 ± 9.87 vs. 65.08 ± 17.32 h; p < 0.01) and PONV was observed in the LRA group, as well as a better level of patient satisfaction at discharge (9.43 ± 0.94 vs. 8.26 ± 1.19; p < 0.01), compared to the N-LRA group. CONCLUSIONS: US-guided TAP and RS block significantly reduces postoperative pain after minor gynecologic laparoscopic surgery and improves patients' post-operative recovery.

Cancer pain seriously reduces the quality of life of cancer patients. However, most research about cancer focuses solely on inhibiting tumor growth, neglecting the issue of cancer pain. Therefore, the development of therapeutic agents with both tumor suppression and cancer pain relief is crucial to achieve human-centered treatment. Here, the work reports curcumin (CUR) and ropivacaine (Ropi) coincorporating CaCO3/PDA nanoparticles (CaPNMCUR+Ropi) that realized efficient tumor immunotherapy and cancer pain suppression. The therapeutic efficiency and mechanism are revealed in vitro and in vivo. The results indicate that CaPNMCUR+Ropi underwent tumor microenvironment-responsive degradation and realized rapid release of calcium ions, Ropi, and CUR. The excessive intracellular calcium triggered the apoptosis of tumor cells, and the transient pain caused by the tumor injection was relieved by Ropi. Simultaneously, CUR reduced the levels of immunosuppressive factor (TGF-ß) and inflammatory factor (IL-6, IL-1ß, and TNF-α) in the tumor microenvironment, thereby continuously augmenting the immune response and alleviating inflammatory pain of cancer animals. Meanwhile, the decrease of TGF-ß leads to the reduction of transient receptor potential vanilloid 1 (TRPV1) expression, thereby alleviating hyperalgesia and achieving long-lasting analgesic effects. The design of the nanosystem provides a novel idea for human-centered tumor treatment in the future.

BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery. METHODS: In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery. RESULTS: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively). CONCLUSION: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence. TRIAL REGISTRATION NUMBER: ChiCTR2200060888 (Chinese Clinical Trial Registry).

Gastric cancer currently has no effective treatment due to its high metastasis and heterogeneity. It has been reported that ropivacaine (Rop) can inhibit the growth, migration, and invasion of gastric cancer. However, the therapeutic mechanism of Rop still needs to be further explored to provide insights for its clinical application. This study aimed to explore the effects of Rop on the growth, migration, and invasion of gastric cancer cells and the underlying mechanisms. The expression levels of SNX10 were assessed in gastric cancer tissues and cell line AGS by qRT-PCR. Cell Counting Kit-8 (CCK8) assay, wound-healing assay, and transwell assay were then used to examine the effects of Rop on the AGS cell viability, migration, invasion, and proliferation, respectively. Additionally, colony formation assay was used to measure cell proliferation ability, and flow cytometry was used to detect apoptosis level. Protein levels of SNX10, SRC, and STAT3 were detected by western blot. According to the experimental results, the decreased SNX10 mRNA expression was observed in gastric cancer tissue and cell line AGS. Rop inhibited the proliferation, migration, and invasion of AGS cells, but promoted apoptosis and upregulated SNX10 expression. Moreover, Rop inhibited the expression of MMP-2 and MMP-9, phosphorylation of SRC and STAT3. SNX10 knockdown could reverse Rop-induced anticancer effects. Collectively, Rop showed a potential role in preventing proliferation and metastasis of gastric cancer. The action mechanism of Rop may be related to the upregulation of SNX10 expression and further inhibition of SRC/STAT3 signaling pathway. Our findings provide new insights into the anticancer properties of Rop.

OBJECTIVE: The aim of this study was to compare the efficacy and safety of ultrasound-guided stellate ganglion block (SGB) with different volumes of 0.375% ropivacaine on sleep quality in patients with insomnia. PATIENTS AND METHODS: A total of 80 patients who were selected to undergo SGB for the treatment of insomnia were enrolled. The patients were divided into saline control group, and low-volume (4 mL), medium-volume (6 mL), and high-volume (8 mL) ropivacaine injection groups according to the random table method. The treatment included 7 blocks with once every three days. The left and right stellate ganglions are alternately blocked. The onset and maintenance time of Horner syndrome, the degree of carotid artery dilation and blood flow velocity before and 20 minutes after the first block, the occurrence of complications such as drug crossing of the midline of the artery and hoarse throat were recorded, and the improvement of sleep disorders was evaluated with the Pittsburgh Sleep Quality Index Scale. RESULTS: Horner syndrome occurred in 100% of all volumes of ropivacaine block. The ipsilateral internal carotid artery was dilated and was accompanied by increased blood flow. The degree of dilation and increase in blood flow were not affected by the volumes of drug injection. There were no serious complications in any group, but the incidences of hoarseness and dysphagia were higher in the medium- and high-volume groups than those in the low-volume group (all p < 0.05). Compared with the low- and medium-volume groups, the high-volume group had a faster onset of action, longer maintenance time, and the highest chance of the drug crossing the artery (all p < 0.05). Compared to those before the pre-block and in the control groups, insomnia was improved in all volume groups after the block with nonsignificant intergroup differences. CONCLUSIONS: 4 mL of 0.375% ropivacaine for ultrasound-guided SGB is sufficient to improve the sleep quality of insomnia patients, whose overall risk is lower than block with 6 mL or 8 mL of ropivacaine.

BACKGROUND: The suprascapular nerve (SSN) is an important nerve that contributes to shoulder joint sensation and movement. The anterior suprascapular nerve block (aSSNB) has the potential for noninferior analgesic effect compared with the interscalene block while preserving respiratory function. This study investigated the median effective volume (MEV) of 0.375% ropivacaine in aSSNB for analgesic effect among patients undergoing arthroscopic shoulder surgery. OBJECTIVES: Our primary objective was the MEV. The secondary objectives included the 24 hour sufentanil consumption, 24 hour patient-controlled analgesia (PCA) presses, and incidences of diaphragm impairment. STUDY DESIGN: Prospective registered (ChiCTR2300070129), single-armed, volume-finding study. SETTING: This study was conducted in a tertiary, single center. METHODS: There were 23 patients who completed the study. Using an up-and-down process, patients enrolled in the study received different volumes of 0.375% ropivacaine for an aSSNB adjusted based on the success or failure of the previous patient in the study's block by increasing or decreasing the volume by 3 mL. The first patient received 15 mL of 0.375% ropivacaine. The nerve blocks were evaluated by the sensory score of the C5 and C6 dermatomes. RESULTS: MEV50 (50% of the patients) was 6 mL (95% CI, 5.78 - 6.78 mL), and MEV95 (95% of the patients) was 13.88 mL (95% CI, 13.37 - 14.87 mL). There was no significant difference in the PCA presses, 24 hour sufentanil consumption, and incidences of diaphragm impairments between successful and unsuccessful blocks. LIMITATIONS: Our study focused on the analgesic effect rather than hemi-diaphragmatic paralysis with 0.375% ropivacaine for an aSSNB. The study also did not test varying ropivacaine concentrations while keeping the volume constant. Further investigation with varying concentrations and a larger sample size is indicated to address the optimal volume and concentration to balance analgesia and diaphragm function. CONCLUSIONS: To produce effective analgesic effect, the MEV50 is 6 mL, and the MEV95 is 13.88 mL in patients undergoing arthroscopic shoulder surgery who receive an aSSNB using 0.375% ropivacaine for analgesia.

Background: The combination of different anesthesia techniques or adjuvant drugs can relieve the stress response to surgery, reduce adverse reactions and improve the clinical outcome. We investigated the effects of subcostal anterior quadratus lumborum block (SQLB) with and without dexmedetomidine (DEX) on postoperative rehabilitation for laparoscopic renal surgery (LRS). Methods: We included 90 patients in this single-center study. All were scheduled for elective laparoscopic radical or partial nephrectomy under general anesthesia (GA). We randomly and evenly assigned them to three groups: Group GA (GA alone), Group QG (SQLB with 30 mL of 0.25% ropivacaine and GA), and Group DQG (SQLB with 30 mL of 0.25% ropivacaine plus 1 µg/kg DEX and GA). The primary outcomes were serum creatinine (Cr) and blood urea nitrogen (BUN) levels; the secondary outcomes included the average numeric rating scale (NRS) scores at rest and during activity within 48 h postoperatively; perioperative opioid consumption; the time to first ambulation, exhaust, and fluid intake, and postoperative adverse reactions. Results: The serum Cr and BUN levels in Group DQG decreased significantly compared with Group GA (P < 0.05). The average NRS scores in Group DQG were significantly lower than other two groups (P < 0.05). Furthermore, the indexes reduced significantly in Group QG compared with Group GA (P < 0.05). Groups DQG and QG had lower consumption of opioid compared with Group GA (P < 0.05). The recovery indicators in Groups DQG and QG were higher quality than Group GA (P < 0.05). The incidences of adverse reactions in Group DQG was significantly lower than the other groups (P < 0.05). Conclusion: SQLB with and without DEX could attenuate postoperative pain, reduce opioids requirement and side effects, as well as facilitate postoperative early rehabilitation. More interesting, SQLB with DEX could confer kidney protection. Clinical Trial Registration Number: The Chinese Clinical Trial Registry (ChiCTR2200061554).

BACKGROUND: Ultrasound-guided supraclavicular brachial plexus block is widely used in upper limb surgery; however, it requires a higher dose (20-30â¯mL) of local anesthetic. In this study, we aimed to determine the 90% minimum effective volume for ultrasound-guided supraclavicular brachial plexus block. METHODS: All patients received an ultrasound-guided two-point injection of 0.5% ropivacaine at a starting volume of 0.18â¯mL/mm2 cross-sectional nerve area. In cases of a successful block, the next patient had the same volume with a probability of 0.89, and the volume was reduced by 0.04â¯mL/mm2 cross-sectional nerve area with a probability of 0.11. When the block failed, the dose was increased by 0.04â¯mL/mm2 cross-sectional nerve area. After 45 cases of successful blocks, the 90% minimum effective volume of local anesthetic was calculated using the centered isotonic regression function. RESULTS: Centered isotonic regression analysis resulted in a 90% minimum effective volume and a 95% confidence interval of 0.189â¯mL/mm2 and 0.176-0.225â¯mL/mm2 for the supraclavicular brachial plexus block. CONCLUSION: A good blocking effect can be achieved with 0.189â¯mL/mm2 of 0.5% ropivacaine with more precise dosing, thereby reducing the risk of local anesthetic poisoning.

Although surgical resection provides a straightforward and effective treatment for most malignant solid tumors, tumor recurrence and acute postoperative pain continue to be two big problems associated with this treatment. To resolve these problems, a nanocrystal composite slow-releasing ropivacaine and doxorubicin was fabricated in this study. Briefly, a self-assembling peptide was used to form nanoparticle complexes with the two drugs, based on which homogeneous nanocrystals were obtained by adjusting the pH. In cultured human melanoma cells, the nanocrystals exhibited improved antitumor activity due to a synergistic effect and enhanced cellular uptake of the two drugs. On the other hand, the nanocrystals could slowly release ropivacaine in vitro and in vivo, generating long-acting analgesia on the rat sciatic nerve block model and incisional pain model. On a nude mouse tumor resection model, the nanocrystals simultaneously suppressed the recurrence of solid tumor and relieved postoperative pain, indicating a potential postoperative treatment for tumor resection patients. This nanocrystal system also suggested a promising and facile strategy for developing multifunctional formulations combining different drugs, which could achieve better therapeutic outcomes in a synergistic and sustained manner.
