Abstract
Background A conclusive evidence regarding the optimal concentration and volume of local anesthetic for quadratus lumborum block is lacking. Methods In this single-center, prospective, randomized, controlled study, 60 patients scheduled for laparoscopic colorectal surgery were randomly assigned to 3 different combinations of volume and concentration of ropivacaine (3 mg/kg) - Group 0.25%, Group 0.375% and Group 0.5%. All subjects received ultrasound-guided posterior quadratus lumborum block prior to the induction. The primary outcome was the complete sensory block rate of surgical site measured at 30 min after quadratus lumborum block, after extubation, at 12, 24, and 48 h after operation. Secondary outcomes were the changes in hemodynamic parameters before and after incision (ΔSBP, ΔDBP and ΔHR), postoperative pain score, the sufentanil consumption after surgery, length of stay and adverse reactions. Results The sensory block rate of surgical site at 5 time points differed significantly among the three groups (P < 0.001). Both Group 0.375% (P < 0.001) and Group 0.5% (P < 0.001) had a higher sensory block rate than Group 0.25%, but no significant difference was observed between the former two. Group 0.375% and Group 0.5% had lower postoperative pain scores, lower sufentanil consumption after surgery and shorter length of stay. No statistical difference was observed in ΔSBP, ΔDBP, ΔHR and the incidence of adverse reactions. Conclusions 0.375% and 0.5% ropivacaine in posterior quadratus lumborum block provide better sensory block of surgical site when compared to 0.25% in laparoscopic colorectal surgery. Trial registration number Chinese Clinical Trials Registry (ChiCTR2100043949).

Abstract
INTRODUCTION Laryngoscopy and intubation are associated with the reflex response of hypertension, tachycardia and other intraoperative complications. Nebulised route drug administration and entropy-guided induction enable optimal intubating conditions. AIMS To compare pre-induction nebulisation between 0.75% ropivacaine and 2% lignocaine in blunting the nasotracheal intubation response. MATERIALS AND METHODS A total of 100 patients undergoing elective faciomaxillary surgeries were prospectively randomised to receive pre-induction nebulisation: 5mL of 2% lignocaine (100mg) (Group L) or 5mL of 0.75% ropivacaine (37.5mg) (Group R). Patients were induced and intubated (nasotracheal) with entropy monitoring. Observed parameters included systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, entropy at baseline, induction, intubation, post-intubation one, three and five minutes, propofol induction dose, electrocardiogram changes and peri-intubation cough reflex. RESULTS Ropivacaine aerosol proved significantly better than lignocaine aerosol on haemodynamics (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate) and cough reflex (p < 0.05). Both groups experienced similar entropy changes and propofol induction dose requirements and no fresh electrocardiogram changes (compared with the baseline). CONCLUSION Pre-induction nebulised ropivacaine offers superior intubating conditions than lignocaine regarding haemodynamic response and cough reflex for faciomaxillary surgeries.

Abstract
BACKGROUND Epidural test dose for labor analgesia is controversial and varies widely in clinical practice. It is currently unclear whether using a portion of the initial dose for analgesia as the test dose delays the onset time of analgesia, compared to the traditional test dose. METHODS One hundred and twenty-six parturients who chose epidural analgesia during labor were randomly assigned to two groups. The first dose in group L was 3 ml 1.5% lidocaine, and in the RF group was 10 ml 0.1% ropivacaine combined with 2 μg/ml fentanyl. After 3 min of observation, both groups received 8 ml 0.1% ropivacaine combined with 2 μg/ml fentanyl. The onset time of analgesia, motor and sensory blockade level, numerical pain rating scale, patient satisfaction score, and side effects were recorded. RESULTS The onset time of analgesia in group RF was similar to that in group L (group RF vs group L, 7.0 [5.0-9.0] minutes vs 8.0 [5.0-11.0] minutes, p = 0.197). The incidence of foot numbness (group RF vs group L, 34.9% vs 57.1%, p = 0.020) and foot warming (group RF vs group L, 15.9% vs 47.6%, p < 0.001) in group RF was significantly lower than that in group L. There was no difference between the two groups on other outcomes. CONCLUSIONS Compared with 1.5% lidocaine 3 ml, 0.1% ropivacaine 10 ml combined with 2 μg/ml fentanyl as an epidural test dose did not delay the onset of labor analgesia, and the side effects were slightly reduced.

Abstract
Tonsillectomy is one of the most common surgical procedures practiced in Otorhinolaryngology. A significant obstacle for the speedy and smooth recovery is early post- operative pain. Pain leads to negative outcomes such as poor intake, tachycardia, anxiety, delayed wound healing and insomnia. Aim to assess and compare the effect of post-incisional infiltration of 0.75% Ropivacaine v/s 0.5% Bupivacaine on post tonsillectomy pain, the on start of oral intake and stay in hospital and to investigate any complications that can arise due to infiltration of the said drugs. 60 Patients above the age of 5 years were posted for tonsillectomy or adenotonsillectomy under general anesthesia. Patients were blinded about the group in which they will be enrolled. Group A received Inj. ropivacaine (0.75%) 2 ml and Group B: received Inj. Bupivacaine (0.50%) 2 ml in each fossa. After surgery, no analgesics were given & patients were observed for the intensity of post-operative pain in the immediate post-operative period, at 2, 4, 6, 12, 24, 48 h and further if not discharged using VISUAL ANALOGUE SCORE (VAS) and VERBAL RATING SCALE(VRS). Post-operative pain assessment was done using VAS and VRS at 2nd, 4th, 6th, 12th, 24th and 48th hour which was found to be lower in Group 'A'. Patients in Group 'A' also started their oral intake sooner, had lesser hospitalization days than group 'B' patients. Longer time for Rescue analgesic and reduced total dose of analgesic required was seen in Group A compared to Group B. This comparative study on Post-incisional infiltration of 2 ml 0.75% Ropivacaine v/s 2 ml 0.5% Bupivacaine has shown that Ropivacaine is a more effective drug in reducing post-operative pain in comparison to Bupivacaine, proven statistically.

Abstract
PURPOSE In this study, we investigated the effect of local injection of ropivacaine and bupivacaine with magnesium sulfate on postoperative pain in vertebral laminectomy surgery. DESIGN This randomized double-blind prospective study was conducted among 60 patients aged 18-65 years old with ASA class I and II. METHODS Group RM: (30 people) received 70 mg ropivacaine (14 ml) plus 1 ml magnesium sulfate (500 mg) volume up to 20 ml with normal saline. Group BM: (30 people) received 70 mg bupivacaine (14 ml) plus 1 ml magnesium sulfate (500 mg) volume up to 20 ml with normal saline. The results were analyzed by SPSS 23 software, and statistical analysis consisted of χ2 test and t-test, and a p value less than .05 was considered significant. FINDINGS Mean pain score based on VAS in 6 and 12 h after surgery in the RM group was lower in the BM group (p < 0.05). The analgesic request frequency in the RM group was lower than the BM group (p = 0.01). The mean morphine consumption in the RM group was 185 mg and in the BM group was 220 mg. According to the T-test, there was a significant difference between the two groups (p = 0.03). there was no significant difference between the mean arterial blood pressure and mean heart rate between the two groups at 6, 12, 24 and 24 h after surgery (p > 0.05). CONCLUSION This study showed that wound infiltration with ropivacaine and magnesium sulfate compared to bupivacaine and magnesium sulfate provided better postoperative analgesia and significantly reduced postoperative opioid consumption in patients undergoing lumbar laminectomy.

Abstract
INTRODUCTION A significant number of women who undergo neuraxial labor analgesia experience breakthrough pain. Prompt mitigation of breakthrough pain is essential to improve maternal and fetal outcomes. We evaluated epidural chloroprocaine compared with ropivacaine in alleviating labor breakthrough pain. METHODS We performed a double-blind randomized controlled clinical trial between May and July 2023. Eligible parturients received epidural analgesia with ropivacaine and sufentanil. Those with breakthrough pain were randomized to receive either 0.125% epidural ropivacaine (group R) or chloroprocaine at concentrations of 0.5% (group C1), 1.0% (group C2), or 1.5% (group C3), all in a volume of 6 mL. The primary outcome was the treatment success rate, indicated by a decrease of at least 4 points on the numerical rating scale pain score 9 min after analgesic injection. Secondary outcomes and adverse effects were also recorded. RESULTS Out of 323 patients receiving epidural analgesia, 192 experienced breakthrough pain. After exclusion of three patients because of protocol deviation, there were 47, 48, 47, and 47 patients in group R, C1, C2, and C3, respectively. Group C3 demonstrated a higher treatment success rate (39/47, 83.0%) in managing breakthrough pain than group R (26/47, 55.3%), group C1 (12/48, 25.0%), and group C2 (30/47, 63.8%) (p < 0.001). Group C3 had lower numerical rating scale scores at 6 and 9 min after injection and required fewer patient-controlled epidural boluses than other groups. In addition, group C3 reported greater satisfaction than the other groups (p < 0.001). No significant differences were observed in obstetric or neonatal outcomes across these groups. CONCLUSION Parturients experiencing breakthrough pain could receive 1.5% epidural chloroprocaine, rather than lower chloroprocaine concentrations and ropivacaine, to achieve more rapid and better pain relief with higher patient satisfaction.

Abstract
PURPOSE To determine the 50% minimum effective concentration (MEC50) and the 95% effective concentration (MEC95) of ropivacaine for ultrasound-guided caudal block during hypospadias repair surgery of pediatric patients. METHODS Children were enrolled with the American Society of Anesthesiologists (ASA) physical status I-II undergoing elective hypospadias repair surgery. Children were grouped into two age groups: toddlerhood (1-3 years old) and preschool (3-6 years old). We measured The MEC50 using Dixon's up-and-down method. The first children received the caudal block with 1.0 mL/kg of 0.15% ropivacaine. We determined each subsequent patient's concentration based on the previous patient's response and adjusted the concentration in intervals of 0.015%. Meanwhile, the probit regression analysis obtains 95% effective concentration (MEC95). In addition, we recorded the general condition, adverse events, and postoperative pain of each child. RESULTS 46 children undergoing elective hypospadias repair surgery were included in this study, 22 in the toddlerhood group and 24 in the preschool group. Of the total number of patients, the caudal block was successful in 25 (54%) and failed in 21 (46%). The MEC50 of 1 ml/kg ropivacaine was 0.102% (95% CI 0.099%, 0.138%) in the toddlerhood group and 0.129% (95% CI 0.124%, 0.138%) in the preschool group. The MEC95 of 1 ml/kg ropivacaine was 0.148% (95% CI 0.131%, 0.149%) in the toddlerhood group and 0.162% (95% CI 0.134%, 0.164%) in the preschool group. Our results showed that ropivacaine concentration was statistically different between preschool children and toddlers (P < 0.001). None of the adverse events occurred. CONCLUSIONS This study showed that children in the preschool group required higher concentrations of ropivacaine than children in the toddler group during ultrasound-guided sacral block combined with non-intubated general anesthesia. At the same time, this method of anesthesia is safe and effective for children undergoing surgery for hypospadias.

Abstract
PURPOSE To investigate the effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine and ropivacaine alone on the quality of postoperative recovery of patients undergoing total laparoscopic hysterectomy (TLH). METHODS Female patients scheduled to undergo a TLH under general anesthesia at Fujian Maternity and Child Health Hospital were included. Before the end of pneumoperitoneum, patients were laparoscopically administered an intraperitoneal infusion of 0.25% ropivacaine 40 ml (R group) or 0.25% ropivacaine combined with 1 µg/kg dexmedetomidine 40 ml (RD group). The primary outcome was QoR-40, which was assessed before surgery and 24 h after surgery. Secondary outcomes included postoperative NRS scores, postoperative anesthetic dosage, the time to ambulation, urinary catheter removal, and anal exhaust. The incidence of dizziness, nausea, and vomiting was also analyzed. RESULTS A total of 109 women were recruited. The RD group had higher QoR scores than the R group at 24 h after surgery (p < 0.05). Compared with the R group, NRS scores in the RD group decreased at 2, 6, 12, and 24 h after surgery (all p < 0.05). In the RD group, the time to the first dosage of postoperative opioid was longer and the cumulative and effective times of PCA compression were less than those in the R group (all p < 0.05). Simultaneously, the time to ambulation (p = 0.033), anal exhaust (p = 0.002), and urethral catheter removal (p = 0.018) was shortened in the RD group. The RD group had a lower incidence of dizziness, nausea, and vomiting (p < 0.05). CONCLUSION Intraperitoneal infusion of ropivacaine combined with dexmedetomidine improved the quality of recovery in patients undergoing TLH.

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.

Abstract
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 ± 1.0 vs. 1.3 ± 0.6 in the epidural group; p = 0.001). 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 ± 15 vs. 102 ± 11 in the epidural group (p = 0.001). 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. LEVEL OF EVIDENCE: 2

Abstract
BACKGROUND With the aging of human society, more and more elderly patients have to undergo surgery and anesthesia. Clinical observations have indicated from time to time that spinal anesthesia in the elderly appears to last longer than in young people, although there is limited research in this area and the mechanism is unclear at present time. This research work is expected to help understand the decline of local anesthetic metabolism in cerebrospinal fluid of elderly patients so as to help them with precise anesthesia and rapid rehabilitation. METHODS Twenty patients with spinal anesthesia in orthopedic lower limb surgery were selected to study the rate of drug metabolism in cerebrospinal fluid in two age groups, i.e.,18-30 years old and 75-90 years old. Ropivacaine in peripheral blood is used as a probe to reflect the speed of drug metabolism in cerebrospinal fluid. The contents of total Aβ protein and hyaluronic acid in the cerebrospinal fluid were investigated as well. RESULTS The equivalent dose of ropivacaine anesthetizes the elderly group for a longer time. The metabolism rate of ropivacaine in an elderly patient was slower than that of a young patient. No significant difference in total Aβ protein between the two groups was observed while hyaluronic acid in the elderly group was significantly higher than that in the young group. CONCLUSIONS This study shows that the dose of ropivacaine should be reduced when used for anesthesia in elderly patients. The cumulation of ropivacaine and HA appears to imitate the degeneration of central lymphatic circulation metabolism in elderly people.

Abstract
OBJECTIVE This trial aimed to identify the Minimum Effective Concentration (MEC90, defined as the concentration which can provide successful block in 90% of patients) of 30 mL ropivacaine for single-shot ultrasound-guided transmuscular Quadratus Lumborum Block (QLB) in patients undergoing Total Hip Arthroplasty (THA). METHODS A double-blind, randomized dose-finding study using the biased coin design up-and-down sequential method, where the concentration of local anesthetic administered to each patient depended on the response from the previous one. Block success was defined as a Numeric Rating Scale (NRS) score during motion ≤ 3 at 6 hours after arrival in the ward. If the block was successful, the next subject received either a 0.025% smaller dose (probability of 0.11) or the same dose (probability of 0.89); otherwise, the next subject received a 0.025% higher ropivacaine concentration. MEC90, MEC95 and MEC99 were estimated by isotonic regression, and the corresponding 95% Confidence Intervals (95% CIs) were calculated by the bootstrapping method. RESULTS Based on the analysis of 52 patients, MEC90, MEC95, and MEC99 of ropivacaine for QLB were estimated to be 0.352% (95% CI 0.334-0.372%), 0.363% (95% CI 0.351-0.383%), and 0.373% (95% CI 0.363-0.386%). The concentration of ropivacaine at 0.352% in a volume of 30 ml can provide a successful block in 90% of patients. CONCLUSIONS For ultrasound-guided transmuscular QLB in patients undergoing THA, 0.352% ropivacaine in a volume of 30 ml can provide a successful block in 90% of patients. Further dose-finding studies and large sample size are required to verify the concentration.

Abstract
BACKGROUND This study was performed to analyze the clinical effect of different concentrations of ropivacaine in the labor analgesia of the dural puncture epidural (DPE) technique for obese puerperae. METHODS One hundred and fifty first-term obese women who received vaginal delivery and required labor analgesia in our hospital were selected prospectively for this study, and divided into groups A, B, and C. The three groups of puerpera were given epidurals with different concentrations of ropivacaine (0.075%, 0.10%, and 0.125%) with sufentanil (0.5 μg/ml) for the labor analgesia regimen. The visual analog scale (VAS), Ramsay scale, and Bromage scale of puerperae before analgesia and at different time points after anesthesia, and analgesic onset time, analgesia time, first PCEA time, PCEA pressing time, ropivacaine consumption, labor time, maternal blood pressure and heart rate, maternal adverse reactions, blood gas analysis in the neonatal umbilical artery, and Apgar score were observed. RESULTS The analgesia onset time, PCEA pressing time, and ropivacaine consumption in group C were lower and the analgesia time and the first PCEA time were longer than those in groups A and B. At T1-T3 and T5, VAS scores of group A were higher than those in groups B and C, Ramsay score of group A was lower than that of groups B and C at T2-T3, and Bromage score of group C at any time point was higher than other two groups. The time of the second stage of labor in groups B and C was longer than that in group A, which in group C was longer than that in group B. Compared with groups A and C, the blood pressure and heart rate of puerperae in group B were closer to normal values. Three different concentrations of ropivacaine had no significant effect on the umbilical artery blood gas analysis indices and Apgar scores at 1st minute and 5th minute in neonates. The incidence of maternal adverse reactions in group C was lower than those in groups A and B. CONCLUSION 0.1% ropivacaine combined with 0.5 μg/ml sufentanil through DPE technique has good analgesic efficacy and few adverse effects in obese puerperae.

Abstract
BACKGROUND Anaesthetic methods and drugs with rapid onset, rapid recovery and better postoperative analgesia are more suitable for rapid recovery in obstetric anaesthesia. We formulated the following hypothesis: a combination of mepivacaine and ropivacaine could provide a longer analgesic effect and have more advantages in terms of rapid-recovery indicators. METHODS A total of 180 pregnant women scheduled to undergo elective caesarean sections were randomly assigned to three surgical groups, which received 2% mepivacaine (Group M), 2% mepivacaine + 0.75% ropivacaine (Group MR) (Volume 1:1) or 0.75% ropivacaine (Group R) through an epidural catheter. The situation of postoperative analgesia and other indicators of rapid recovery were recorded. RESULTS One hundred and fifty patients were included in the final analysis. Their demographic data were similar. The visual analogue scale (VAS) scores of Group MR and Group R were lower than Group M at 1 and 2 h after surgery both at rest and with movement (P < 0.05), and the time to first ambulation in Group MR (17.38 ± 2.06 h) and Group M (17.20 ± 2.09 h) was shorter than that in Group R (22.18 ± 1.74 h) (P < 0.05). CONCLUSION Application of 2% mepivacaine combined with 0.75% ropivacaine for epidural anaesthesia can provide longer postoperative analgesia and earlier ambulation, these effect may be more suitable than that of 2% mepivacaine or 0.75% ropivacaine alone for caesarean section.

Abstract
Background Dexmedetomidine is known to prolong the analgesic duration of spinal anesthesia, but it can be challenging to achieve further extension without opioids. Therefore, this study aimed to investigate a novel analgesic strategy using dexmedetomidine as an adjuvant to spinal-epidural anesthesia for elective cesarean surgery. Methods The study was a randomized, double-blind, controlled trial conducted at a single center. Sixty parturients who underwent elective cesarean were randomly assigned to either group C or group D. Group D received an intrathecal injection of 12.5 mg ropivacaine and 5 μg dexmedetomidine followed by continuous epidural patient-controlled analgesia (PCA) infusion with a total volume of 100 ml, containing 0.2 % ropivacaine and 0.5 μg/kg dexmedetomidine. Group C received an intrathecal injection of 12.5 mg ropivacaine with an equivalent saline placebo followed by a similar PCA infusion, containing 0.2 % ropivacaine and an equivalent saline placebo. Results The primary outcome was visual analog scale score on movement at 24 h after surgery. The results showed that the rest and motion pain scores in group D were significantly lower than those in group C at 6 h, 12 h, and 24 h after surgery (P < 0.05), with the differences at 24 h were 5.0 (5.0, 5.0)in group D versus 5.0 (5.0, 6.0) in group C (P = 0.04). Additionally, the time to the first PCA in group D was significantly longer than that in group C (P < 0.05), as well as the time of sensory and motor recovery. Conclusions Whole-course application of dexmedetomidine as an adjuvant to spinal-epidural anesthesia could effectively extend the analgesic duration of ropivacaine to 24 h following elective cesarean surgery.

Abstract
BACKGROUND Ropivacaine is present in plasma in both protein-bound and free forms. The free form is responsible for the occurrence of toxic side effects. During obstetric epidural analgesia, free ropivacaine enters the fetal circulation depending on various factors. The aim of this study was to analyse a potential association between ropivacaine concentrations in maternal and fetal plasma and hence the extent of fetal exposure to ropivacaine. METHODS In this prospective monocentre study, parturients who met the following criteria were included in the study: 1. epidural administration as part of obstetric anaesthesia, and 2. subsequent intrapartum caesarean delivery, which 3. was performed after an epidural bolus administration of ropivacaine within the existing epidural analgesia. Total and free ropivacaine concentrations were analysed in maternal blood at baseline, prior to epidural bolus administration for caesarean delivery, and in maternal and fetal (umbilical venous, oxygenated) blood at delivery. The results are presented as mean ± SD or median (25/75th percentile). RESULTS We screened 128 parturients who went into labour at term and requested epidural analgesia, of whom 39 were ultimately included in the study. An intrapartum caesarean delivery was performed after the epidural application of 207 (166/276) mg ropivacaine during an epidural treatment period of 577 (360/1010) min. Total and free ropivacaine concentrations were 1402 ± 357 ng/ml and 53 ± 46 ng/ml, respectively, in maternal venous blood and 457 ± 243 ng/ml and 43 ± 27 ng/ml, respectively, in fetal blood. The maternal total and free ropivacaine concentrations were significantly correlated (r = 0.873; P < 0.0001). CONCLUSION The results of the present study suggest that determining the concentration of free ropivacaine in maternal blood may be a feasible option for estimating neonatal exposure to ropivacaine.

Abstract
STUDY OBJECTIVE The study aimed to evaluate the efficacy of ropivacaine in providing postoperative analgesia for children undergoing cleft palate repair. METHODS A double-blinded, randomized controlled trial was conducted on sixty-four children scheduled for cleft palate repair. The patients received either local infiltration with 1% lidocaine or 0.2% ropivacaine before incision. The primary outcome was the postoperative average pain score, and secondary outcomes included pain scores at various time points, consumption of flurbiprofen and hydromorphone, effectiveness of nurse-controlled analgesia pump, and incidence of bradycardia, vomiting, and respiratory depression. MAIN RESULTS The results showed that the postoperative average pain score was significantly lower in the ropivacaine group compared to the lidocaine group (1.27±0.28 vs. 1.75±0.29, P<0.001). Pain scores at multiple postoperative time points were also lower in the ropivac:aine group. Additionally, consumption of flurbiprofen and hydromorphone was lower, and ineffective compressions of the nurse-controlled analgesia pump were reduced in the ropivacaine group. The incidence of vomiting, bradycardia, and respiratory depression did not show significant differences between the two groups. CONCLUSION Local infiltration with ropivacaine effectively provided postoperative analgesia for children undergoing cleft palate repair without major side effects. It was found to be superior to lidocaine in reducing the need for additional rescue analgesia.

Abstract
BACKGROUND Postoperative analgesia in the cardiothoracic ICU has traditionally relied on intravenous opioids. Thoracic nerve blocks are attractive alternatives for analgesia that reduce the requirement for opioids, but their safety and feasibility remain unclear. METHODS Sixty children were allocated randomly to three groups: group C received intravenous opioids alone, while group SAPB (deep serratus anterior plane block) and group ICNB (intercostal nerve block) received opioids combined with ultrasound-guided regional nerve blocks (0.2% ropivacaine 2.5 mg.kg-1) after patients were transferred to the ICU. The primary outcome was opioid requirement in the first 24 h after surgery. Other outcomes included the postoperative FLACC scale value, tracheal extubation time, and plasma ropivacaine concentrations after the block. RESULTS The mean [sd] cumulative dose of opioids administered postoperatively within 24 h in the SAPB (168.6 [76.9] μg.kg-1) and ICNB groups (170.0 [86.8] μg.kg-1) were significantly lower by nearly 53% than those in group C (359.3 [125.3] μg.kg-1, p = 0.000). The tracheal extubation time was shorter in the regional block groups than that in the control group, but the difference was not statistically significant (p = 0.177). The FLACC scale values at 0, 1, 3, 6, 12, and 24 h post-extubation were similar in the three groups. The mean peak plasma ropivacaine concentrations in the SAP and ICNB groups were 2.1 [0.8] and 1.8 [0.7] mg.L-1, respectively, 10 min post-block and then slowly decreased. No noticeable complications associated with regional anesthesia were observed. CONCLUSIONS Ultrasound-guided SAPB and ICNB provided safe and satisfactory early postoperative analgesia while reducing opioid consumption following sternotomy in pediatric patients.

Abstract
Prolonged exposure to local anesthetics (LAs) or intrathecal administration of high doses of LAs can cause spinal cord damage. Intraspinal administration of LAs is increasingly being used in children and neonates. Therefore, it is important to study LA-related spinal cord damage and the underlying mechanism in developmental models. First, neonatal Sprague-Dawley rats received three intrathecal injections of 0.5% ropivacaine, 1% ropivacaine, 2% ropivacaine or saline (90-min interval) on postnatal day 7. Electron microscopy, luxol fast blue staining and behavioral tests were performed to evaluate the spinal neurotoxicity caused by ropivacaine at different concentrations. Western blot analysis and immunostaining was performed to detect the expression changes of p-Akt, Akt, myelin gene regulatory factor (MYRF) and myelin basic protein (MBP) in the spinal cord treated with different concentrations of ropivacaine. Our results showed that 1% or 2% ropivacaine impaired myelination in the spinal cord and induced sensory dysfunction, but 0.5% ropivacaine did not. Moreover, 1% or 2% ropivacaine decreased the expression of p-Akt, MYRF and MBP in the spinal cord. Then, in order to further explore the role of these proteins in this model, the Akt-specific activator (SC79) was intraperitoneally injected 30 min before 2% ropivacaine treatment. Interestingly, SC79-mediated activation of Akt partly rescued ropivacaine-induced myelination impairments and sensory dysfunction. Overall, the results showed that ropivacaine caused spinal neurotoxicity in a dose-dependent manner in neonatal rats and that activation of the Akt partly rescued ropivacaine-induced these changes. These data provide insight into the neurotoxicity to the developing spinal cord caused by LAs.

Abstract
To evaluate the sensory and motor effects promoted by a combined sciatic and femoral nerve block in calves using two approaches. Six calves were used, in a crossover study. Ultrasound combined with neurostimulation, was used to perform the following block combinations: the proximal approach (PA), which consisted of the association of the parasacral approach (sciatic nerve block) and ventral to the ilium approach (femoral nerve block); distal approach (DA) consisted of the association of a lateral approach to the pelvic limb approach (sciatic nerve block), and an inguinal approach, underneath the femoral trigone (femoral nerve block). Pressure algometry and motor function of the limb where evaluated. Mechanical nociceptive threshold (MNT) increase, and ataxia duration means were 9.5 ± 0.7 kg and 10.4 ± 3.9 hr for PA and 10.4 ± 3.9 kg and 12.7 ± 1.9 hr for DA, respectively with no significant difference. There was no significant difference between MNT elevation time and the duration of ataxia using the same approach. The DA treatment showed significant MNT elevation in 72% of the tested regions, while the PA treatment showed an elevation in 100% regions tested. Topographic approaches closer to where the spinal nerves emerge produced a larger desensitised area.

Abstract
BACKGROUND Ultrasound-guided supraclavicular brachial plexus block is widely used in upper limb surgery; however, it requires a higher dose (20-30 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 0.18 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 0.04 mL/mm2 cross-sectional nerve area with a probability of 0.11. When the block failed, the dose was increased by 0.04 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 0.189 mL/mm2 and 0.176-0.225 mL/mm2 for the supraclavicular brachial plexus block. CONCLUSION A good blocking effect can be achieved with 0.189 mL/mm2 of 0.5% ropivacaine with more precise dosing, thereby reducing the risk of local anesthetic poisoning.

Abstract
The objective of this investigation is to assess the efficacy of ropivacaine on intraoperative and postoperative endpoints like operative time, blood loss, pain, and bleeding among adult's patients undergoing for tonsillectomy. PubMed, CENTRAL, Scopus, and Web of Science databases were screened from inception until November 2022. The included RCTs were evaluated for risk of bias via risk of bias tool (second version). All endpoints were summarized as mean difference (MD) or standardized mean difference (SMD) for continues outcomes, and risk ration (RR) for dichotomous outcomes, under random-effect model. Four RCTs met our PICOS criteria, comprising a total of 257 patients. Regarding postoperative pain, there was a significant difference that favor ropivacaine group compared with placebo group within hours (n = 4 RCTs, SMD = -0.92, 95% CI [-1.57, -0.26], p = 0.006), and within days (n = 4 RCTs, SMD = -050, 95% CI [-0.82, -0.18], p = 0.002). However, there were no significant difference between ropivacaine and placebo groups I terms of operative time (n = 3 RCTs, SMD = -0.17, 95% CI [-0.45, 0.11], p = 0.22), intraoperative blood loss (n = 2 RCTs, SMD = -0.37, 95% CI [-1.41, 0.67], p = 0.49), and postoperative bleeding (n = 4 RCTs, RR = 2.27, 95% CI [0.90, 5.73], p = 0.08). In conclusion, administration of ropivacaine was associated with less postoperative pain among adult's patients who undergoing tonsillectomy. However, there were no benefit in term of reduction in operative time, intraoperative blood loss, and postoperative hemorrhage.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is a common malignancy. Local anesthetics were displayed powerful effects against various cancers. This study aims to probe the functions and molecular mechanism of ropivacaine in RCC. METHODS Different concentrations of ropivacaine were performed to administrate RCC cells including 786-O and Caki-1 cells. Cell viability and cell apoptosis were examined using CCK-8 and flow cytometry, respectively. Cell migration and invasion were determined by transwell assay. RMRP and CCDC65 expression was firstly predicted using TCGA dataset and further validated in RCC cells using qRT-PCR and western blot. The interactions among RMRP, EZH2 and CCDC65 were verified by RNA immunoprecipitation (RIP) and chromatin immunoprecipitation (ChIP) assays. RESULTS Ropivacaine effectively suppressed RCC cell viability, migration and invasion and enhanced cell apoptosis rate. Aberrantly elevated RMRP expression in RCC tissues was predicted by TCGA database. Interestingly, overexpressed RMRP observed in RCC cells could be also blocked upon the administration of ropivacaine. Likewise, RMRP knockdown further strengthened ropivacaine-mediated tumor suppressive effects on RCC cells. In terms of mechanism, RMRP directly interacted with EZH2, thereby modulating the histone methylation of CCDC65 to silence its expression. Moreover, ropivacaine inhibited tumor growth in mice bearing RCC tumor through regulating RMRP/EZH2/CCDC65 axis. CONCLUSION In sum up, our work revealed that ropivacaine suppressed capacities of RCC cell viability, migration and invasion through modulating the RMRP/EZH2/CCDC65 axis, which laid the experimental foundation of ropivacaine for clinical application in the future.

Abstract
Background Ropivacaine is a local anesthetic commonly used in regional nerve blocks to manage perioperative pain during lung cancer surgery. Recently, the antitumor potential of ropivacaine has received considerable attention. Our previous study showed that ropivacaine treatment inhibits the malignant behavior of lung cancer cells in vitro. However, the potential targets of ropivacaine in lung cancer cells have not yet been fully identified. This study aimed to explore the antitumor effects and mechanisms of action of ropivacaine in lung cancer. Methods Lung cancer A549 cells were treated with or without 1 mM ropivacaine for 48 h. Quantitative proteomics was performed to identify the differentially expressed proteins (DEPs) triggered by ropivacaine treatment. STRING and Cytoscape were used to construct protein-protein interaction (PPI) networks and analyze the most significant hub genes. Overexpression plasmids and small interfering RNA were used to modulate the expression of key DEPs in A549 and H1299 cells. MTS, transwell assays, and flow cytometry were performed to determine whether the key DEPs were closely related to the anticancer effect of ropivacaine on the malignant behavior of A549 and H1299 cells. Results Quantitative proteomic analysis identified 327 DEPs (185 upregulated and 142 downregulated proteins) following ropivacaine treatment. Retinoblastoma-binding protein 4 (RBBP4) was one of the downregulated DEPs and was selected as the hub protein. TCGA database showed that RBBP4 was significantly upregulated in lung cancer and was associated with poor patient prognosis. Inhibition of RBBP4 by siRNA resulted in a significant decrease in the proliferation and invasive capacity of lung cancer cells and the induction of cell cycle arrest. Additionally, the results indicated RBBP4 knockdown enhanced antitumor effect of ropivacaine on A549 and H1299 cells. Conversely, the overexpression of RBBP4 using plasmids reversed the inhibitory effects of ropivacaine. Conclusion Our data suggest that ropivacaine suppresses lung cancer cell malignancy by downregulating RBBP4 protein expression, which may help clarify the mechanisms underlying the antitumor effects of ropivacaine.

Abstract
PURPOSE Femoral nerve block (FNB) is widely used in patients undergoing knee arthroscopy. However, the most commonly used concentration of ropivacaine (0.2% or above) may cause an unexpected decrease in the muscle strength of the quadriceps. Therefore, a lower concentration of ropivacaine (0.1%) for FNB was administered to investigate the effect on quadriceps strength and postoperative pain after knee arthroscopy. METHODS This was a double-blind, randomized, controlled trial (ChiCTR2000041404). A total of 83 patients scheduled for elective knee arthroscopy were randomized to receive 0.1% or 0.2% ropivacaine for FNB under ultrasound guidance. The primary outcomes were quadriceps strength and numerical rating scale (NRS) pain score. Quadriceps strength was measured before surgery and 6 h and 24 h after surgery, while NRS score was recorded before surgery, at the postanaesthesia care unit (PACU), and 6 h and 24 h after surgery. Multiple linear regression tests were used to compare the differences in quadriceps strength and NRS score between the two groups. Two-factor analysis of variance, using the factors group and time of measurement, was used for repeated NRS scores. Secondary outcomes included knee mobility, side effects, patient satisfaction, and length of hospital stay. RESULTS The mean (SD) quadriceps strength at 6 h after surgery was 7.5 (5.7) kg for the 0.1% ropivacaine group and 3.0 (4.4) kg for the 0.2% ropivacaine group. The mean difference adjusted for baseline characteristics was - 5.2 (95% CI - 7.2 to - 3.1) kg (P < 0.001). There was no significant difference between the two groups in quadriceps strength at 24 h after surgery. The mean differences in the average NRS score and maximum NRS score in the PACU were - 0.6 (P = 0.008) and - 1.0 (P < 0.001), respectively. There was no significant difference in NRS score at 6 h or 24 h after surgery. Two-factor analysis of variance showed no significant difference in the interaction factors of time and group for average NRS score and maximum NRS score. CONCLUSIONS Compared with 0.2% ropivacaine, 0.1% ropivacaine for FNB preserved quadriceps strength at 6 h after knee arthroscopy while providing similar analgesic effects. LEVEL OF EVIDENCE I.

Abstract
Prolonged analgesia is important to safeguard the patient's comfort and safety during and after surgery in clinical practice. To meet the demand for prolonged analgesia, medical professionals often resort to increasing drug frequency, which may lead to poor patient compliance and serious complications due to drug overdose. Therefore, it is of great interest to develop controlled-release drug delivery systems for local anesthetics, enabling slow and controlled drug release to prolong the analgesic effect and minimize systemic toxicity. In this study, we utilized an electrospinning technique to fabricate nonwoven poly(caprolactone) (PCL) fibrous membranes loaded with Ropivacaine and performed proof-of-principle experiments on both in vitro drug release tests and in vivo animal tests, to further prolong the analgesic effect of Ropivacaine and improve postoperative local pain management and chronic pain treatment. Material characterization and in vitro drug release studies confirmed the feasibility of the Ropivacaine-loaded PCL fibrous membranes for sustained release. The drug loading content and drug loading efficiency of Ropivacaine-loaded fibrous membrane are 8.7 ± 0.3 wt% and 96 ± 3 wt%, respectively. Evaluation in an animal model demonstrated prolonged anesthesia effects along with excellent biocompatibility and stability. At 72 h, the cumulative release accounted for approximately 50% of the drug loading content. This study offers novel approaches and strategies for clinical postoperative pain management and chronic pain treatment, while providing new insights and directions for the design of local anesthetic controlled-release delivery systems.

Abstract
Background The use of local anesthetics as part of multimodal analgesia is an attractive concept in pediatric patients, since the evaluation and management of pain is a challenge in children under 7 years of age. Despite having guidelines and multiple studies on volume calculation, no safe and effective recommendation has been issued. Objective To demonstrate that ultrasound-guided caudal block with a dose of 0.75 mL/kg of 0.2% ropivacaine has the same analgesic effect as a dose of 1.2 mL/kg. Material and methods Randomized, prospective, longitudinal, comparative equivalence clinical trial. One hundred patients 0-7 years of age scheduled for elective or emergency infraumbilical surgery were enrolled between April 2021 and January 2022. Children were randomized 1:1 to be assigned to ultrasound-guided caudal block. Results 100 patients divided into two groups with 0.2% ropivacaine volumes (0.75 mL vs. 1.2 mL). Both groups demonstrated the trans-anesthetic and post-anesthetic sedoanalgesia variables without significant differences for both groups on the FLACC pain scale after surgery and in recovery (p > 0.5), in the pain reassessment on the FLACC scale in the office called chronic pain (p > 0.5) in both groups. No complications were reported in the follow-up consultations and no arrhythmias were reported in both groups during surgery. Conclusions the results of both groups did not show differences between a volume of 0.75 mL and 1.2 mL, the administration of 0.2% ropivacaine is favored with the use of ultrasound, which allows effective administration of lower doses of local anesthetic with reduced risk of complications. It is necessary to carry out studies in other types of surgery to compare the use of less volume of local anesthetic compared to the Melman formula used in this study.

Abstract
OBJECTIVES The painless postoperative period can be significantly prolonged by using long-acting local anesthetics such as ropivacaine, though these local anesthetics are known for their slower onset of action. To compensate for this, a mixture of short-onset (e.g., lidocaine) and long-acting local anesthetics is used. However, the efficacy of such an anesthetic cocktail has not been elucidated in the field of oral and maxillofacial surgery. MATERIALS AND METHODS To address the research purpose, this prospective randomized controlled trial included 56 patients scheduled for impacted mandibular third molar extraction. All patients received the inferior alveolar nerve block (IANB) using either 2% lidocaine with epinephrine or a 1:1 mixture of 2% lidocaine with epinephrine and 0.75% ropivacaine. RESULTS Patients anesthetized using the lidocaine-ropivacaine mixture showed significantly prolonged postoperative analgesia and pain control than those anesthetized using lidocaine only. CONCLUSIONS IANB using a lidocaine-ropivacaine mixture can provide prolonged postoperative anesthesia and pain control with extraction of mandibular third molars. CLINICAL RELEVANCE This method can be a noteworthy addition to existing methods of local anesthesia for the extraction of mandibular third molars.

Abstract
PURPOSE Laparoscopic intraperitoneal instillation of local anaesthetic in bariatric surgery proven to reduce postoperative pain. Limited data are available regarding the use of instillation ropivacaine and its impact on the recovery of respiratory effort. This study aims to evaluate the efficacy of laparoscopic intraperitoneal instillation of ropivacaine in reducing acute postoperative pain and enhancing the recovery of respiratory effort in laparoscopic sleeve gastrectomy. MATERIALS AND METHODS This double-blinded RCT enrolled 110 patients who underwent laparoscopic sleeve gastrectomy at Hospital Canselor Tuanku Muhriz UKM from November 2020 to May 2021. Any patients with previous abdominal surgery, chronic kidney disease, or liver disease were excluded. The patients were randomised into two groups: (i) the IPLA group which received ropivacaine intraperitoneal instillation at the dissected left crus and (ii) the placebo group (sterile water instillation). Perioperative analgesia was standardised. The first 24-h postoperative pain was assessed using a VAS. The respiratory effort was assessed using incentive spirometry simultaneously. RESULTS Total of 110 patients were recruited. The VAS score was lower with an enhanced recovery of respiratory effort in the local anaesthetic group compared to the placebo group (P < 0.05) within the first 24 h postoperatively. In addition, the placebo group required additional postoperative analgesia (P < 0.05). No side effects were reported with the use of intraperitoneal instillation of ropivacaine. CONCLUSION The use of intraperitoneal instillation of ropivacaine in laparoscopic sleeve gastrectomy is recommended as it is safe, effectively reduces acute postoperative pain, and enhances the recovery of respiratory effort postoperatively.

Abstract
PURPOSE This study investigated whether the divided method of multi-level intercostal nerve block (ML-ICB) could reduce the ropivacaine dose required during thoracoscopic pulmonary resection, while maintaining the resting postoperative pain scores. METHODS This retrospective, single-cohort study enrolled 241 patients who underwent thoracoscopic pulmonary resection for malignant tumors between October 2020 and March 2022 at a cancer hospital in Japan. ML-ICB was performed by surgeons under direct vision. The differences in intraoperative anesthetic use and postoperative pain-related variables at the beginning and end of surgery between group A (single-shot ML-ICB; 0.75% ropivacaine, 20 mL at the end of the surgery) and group B (divided ML-ICB, performed at the beginning and end of surgery; 0.25% ropivacaine, 30 mL total) were assessed. The numerical rating scale (NRS) was used to evaluate pain 1 h and 24 h postoperatively. RESULTS Intraoperative remifentanil use was significantly lower in group B (14.4 ± 6.4 μg/kg/h) than in group A (16.7 ± 8.4 μg/kg/h) (P = 0.02). The proportion of patients with NRS scores of 0 to 3 at 24 h was significantly higher in group B (85.4%, 106/124) than in group A (73.5%, 86/117) (P = 0.02). The proportion of patients not requiring postoperative intravenous rescue drugs was significantly higher in group B (78.2%, 97/124) than in group A (61.5%, 72/117) (P < 0.01). CONCLUSION The divided method of ML-ICB could reduce the intraoperative remifentanil dose, decrease the postoperative pain score at 24 h, and curtail postoperative intravenous rescue drug use, despite using half the total ropivacaine dose intraoperatively.

Abstract
BACKGROUND Intrathecal dexmedetomidine, as an adjuvant to local anesthetics, has been reported to improve the quality of spinal anesthesia and reduce the required local anesthetic dose. However, the optimal dosage regimen for intrathecal dexmedetomidine combined with plain ropivacaine for cesarean section (CS) remains undetermined. The present study aimed to determine the median effective dose (ED50) of intrathecal dexmedetomidine as an adjuvant to plain ropivacaine for spinal anesthesia during CS. METHODS Sixty parturients undergoing CS were randomly assigned to either group: plain ropivacaine 8 mg (Group Rop8) or plain ropivacaine 10 mg (Group Rop10). The initial dosage of intrathecal dexmedetomidine in each group was 5 µg. The effective dose was defined as a bilateral sensory block at the level of T6 or above to pinprick attained within 10 min after intrathecal injection, without the need for supplementary intraoperative epidural anesthesia. Effective or ineffective responses were determined, followed by a 1 µg increment or decrement in the dose of intrathecal dexmedetomidine for the next parturient using up-down sequential allocation. ED50 were calculated using probit regression. RESULTS The ED50 of intrathecal dexmedetomidine with plain ropivacaine was 5.9 µg (95% confidence interval [CI], 4.9-7.4 µg) in Group Rop8 and 3.1 µg (95% CI, 0.1-4.8 µg) in Group Rop10 (P < 0.05). Hemodynamic stability, side effects, patient satisfaction and neonatal outcomes were comparable between the two groups. CONCLUSIONS The present data suggested that the ED50 of intrathecal dexmedetomidine as an adjuvant to 8 mg and 10 mg plain ropivacaine in spinal anesthesia during cesarean section was approximately 6 µg and 3 µg, respectively.

Abstract
A 74-year-old male was diagnosed with osteomyelitis of the left mandible requiring marginal mandibulectomy under general anesthesia. However, the patient's pulmonary function tests demonstrated findings consistent with severe chronic obstructive pulmonary disease, classified as stage III. The consulting pulmonologist explained the increased risk of respiratory complications associated with general anesthesia and advised against its use. Therefore, we opted to perform the surgery under moderate sedation using 0.2% ropivacaine administered via bilateral ultrasound-guided inferior alveolar nerve blocks (UGIANBs) and an indwelling catheter with a pump for continuous perioperative local anesthesia and prolonged postoperative analgesia. This approach delivered excellent local anesthetic effects without any need for rescue medications or complications. Use of UGIANBs along with an indwelling catheter and pump may provide adequate local anesthesia and postoperative analgesia in patients with contraindications for general anesthesia.

Abstract
Objective The aim of this study was to compare the impacts of 0.15% ropivacaine alone and 0.15% ropivacaine combined with sufentanil on epidural labor analgesia. Methods A total of 297 eligible primiparae were randomly divided into group A (n=149, 0.15% ropivacaine + sufentanil) and group B (n=148, 0.15% ropivacaine). Visual analogue scale (VAS) scores prior to analgesia and 20 min following epidural medication, the maximum VAS score during labor, dosage of analgesic drugs, modified Bromage score, satisfaction degree, labor duration, delivery mode, 1-min and 5-min Apgar scores of newborns, adverse reactions during analgesia, and fever during labor were recorded. Results Group A and B had similar VAS scores 20 min following epidural medication and maximum score during labor (P>0.05), which significantly fell compared with those before labor analgesia (P<0.05). The occurrence rates of nausea and vomiting were of significant difference (P<0.05). Conclusion 0.15% ropivacaine alone achieves a comparable epidural labor analgesia effect to that of 0.15% ropivacaine + 0.05 µg/mL sufentanil on primiparae.

Abstract
Although the duration of analgesia provided by a single-shot nerve block is limited, perineural dexmedetomidine significantly enhances nerve blocks during extremity surgery. This study aimed to investigate the role of dexmedetomidine added to ropivacaine in femoral nerve blocks for postoperative analgesia of the anterolateral thigh (ALT) flap donor site in patients with oral cancer. Fifty-two participants scheduled for maxillofacial tumor resection and reconstruction using an anterolateral thigh flap were randomly allocated to either the Ropi group (femoral nerve block with ropivacaine) or the Ropi + Dex group (femoral nerve block with ropivacaine plus dexmedetomidine). The primary outcome was the duration of the sensory block, while the secondary outcomes were 24 h postoperative sufentanil use, number of patients using rescue analgesics, vital signs, postoperative pain score, incidence of agitation, and presence of adverse effects. Dexmedetomidine plus ropivacaine significantly prolonged the duration of sensory block compared with ropivacaine alone (10.4 ± 0.9 h vs 14.0 ± 1.3 h; P < 0.001). Age was positively correlated with increased duration of sensory block (r = 0.300; P = 0.033). Postoperative pain scores at the donor sites were lower in the Ropi + Dex group than in the Ropi group, at 12 h after surgery (P < 0.001). Although there were no statistically significant differences in the incidence of bradycardia between the two groups, four patients treated with dexmedetomidine experienced episodes of bradycardia. Perineural dexmedetomidine prolonged the duration of femoral nerve block and reduced postoperative pain scores at the ALT flap donor sites in patients with oral cancer.

Abstract
BACKGROUND Erector spinae plane block (ESPB) improves postoperative analgesia and significantly enhances the quality of recovery (QoR) after video-assisted thoracoscopic lobectomy surgery (VATLS). However, it is not known whether the use of dexmedetomidine (Dex) as an adjunct for ropivacaine to ESPB affects the QoR after VATLS. The purpose of this study was to explore the effects of different Dex dosages as an adjunct for ropivacaine in combination with ultrasound-guided ESPB on the quality of postoperative recovery in patients with VATLS. METHODS In this single-center, double-blind, randomized study, 120 patients between the ages of 18 and 65 who were scheduled for VATLS from december 2021 and october 2022 in our hospital under general anesthesia were randomly divided into three groups: ultrasound-guided ESPB with 30 mL of 0.5% ropivacaine (Group R), ultrasound-guided ESPB 0.5% ropivacaine plus 0.5 µg/kg Dex (Group RD1), and ultrasound-guided ESPB 0.5% ropivacaine plus 1.0 µg/kg Dex (Group RD2), ultrasound-guided ESPB was administrated at the T5 vertebral level before surgery. The primary outcome was the QoR-15 score 24 h after the surgery. The secondary outcomes included the QoR-15 scores at 12 h, 48 h, and 72 h after the operation, visual analogue scale (VAS) scores at 8 h, 12 h, 24 h, and 48 h after surgery, cumulative flurbiprofen consumption, postoperative nausea and vomiting (PONV), postoperative bradycardia, and hypotension. RESULTS The QoR-15 scores were higher in group RD2 than the R and RD1 groups on postoperative day 1 (P < 0.05), in addition, no significant difference was found in the QoR-15 scores between groups R and RD1 on postoperative day 1. The VAS scores were significantly lower in group RD2 than in groups RD1 and group R 12-24 h after surgery (P < 0.05). No significant differences were observed in the QoR-15 and VAS scores at 48 and 72 h after surgery between the three groups. The cumulative flurbiprofen consumption was markedly reduced during the 72 h after surgery in the RD2 group (P < 0.05). The incidence of postoperative nausea and vomiting was lower in the RD2 group (P < 0.05). CONCLUSIONS The combination of 1 µg/kg dexmedetomidine as an adjunct with 0.5% ropivacaine 30 ml for erector spinae plane block significantly improved the postoperative quality of recovery and provided better postoperative analgesia on postoperative day 1 in patients undergoing Video-assisted thoracoscopic lobectomy surgery. However, dexmedetomidine (1 µg/kg) as an adjunct for ropivacaine combined with erector spinae plane block did not enhance the postoperative quality of recovery at 48 and 72 h postoperatively. TRIAL REGISTRY NUMBER The number of this clinical trial registry is ChiCTR2100053230, date of registration: 16/11/ 2021).

Abstract
Background To improve the quality of intraoperative and postoperative analgesia during spinal anesthesia, intrathecal opioids are used as adjuvant drugs in combination with local anesthetics. Objectives This study aimed to compare the intrathecal injection of ropivacaine-fentanyl with ropivacaine-sufentanil in terms of the duration of analgesia after cesarean section (CS). Methods This randomized, double-blind clinical trial study was conducted on women referred to Imam Khomeini Hospital of Ahvaz City for elective CS in 2021. A total of 51 patients were randomly divided into 2 groups. The first group (n = 25) received ropivacaine (17.5 mg) + fentanyl (25 μg), while the second group (n = 26) received ropivacaine (17.5 mg) + sufentanil (2.5 μg) for spinal anesthesia. Eventually, several parameters were investigated, including the duration of sensory and motor block, duration of analgesia (based on the Visual Analog Scale (VAS)), hemodynamic parameters, and possible complications. Results The duration of surgery (P = 0.059) and the duration of motor block (P = 0.962) were not significantly different between the 2 groups. The mean duration of analgesia (from the time of entering recovery to reaching VAS = 3) was 203.12 ± 72.93 and 207.46 ± 69.59 minutes in the fentanyl and sufentanil groups, respectively (P = 0.658). Systolic and diastolic blood pressure (SBP/DBP) drops in minute 5 were observed more frequently in the sufentanil group than in the fentanyl group (P = 0.027 and P = 0.002, respectively). At the other time points, however, no significant difference was observed between the 2 groups in terms of hemodynamic variables (P > 0.05). Finally, the frequency of pruritus was higher in the sufentanil group than in the fentanyl group (26.9% vs. 4.0%; P = 0.024). Conclusions Adding fentanyl or sufentanil to intrathecal ropivacaine provides a similar duration of analgesia. However, fentanyl was associated with better hemodynamic stability and a lower incidence of pruritus.

Abstract
INTRODUCTION Epidural infusion with low local anesthetic concentrations with opiates decrease the severity of the motor blockade associated. The present study aims to compare the analgesic efficacy and the motor blockade between two local anesthetic epidural infusions: levobupivacaine 0.0625% + fentanyl 2mcg/mL versus ropivacaine 0.075% + fentanyl 2mcg/mL. MATERIALS AND METHODS In a single-blind prospective randomized study, 60 laboring parturient had continuous epidural analgesia as follows: 30 of them received levobupivacaine 0.0625% + fentanyl 2mcg/mL and 30 of them received ropivacaine 0.075% + fentanyl 2mcg/mL and rates of infusion were adjusted to the height. Analgesic, motor blockade and satisfaction records were collected as well as maternal and neonate adverse events. RESULTS After 2 h of the catheter placement, patients who received levobupivacaine showed a mean VAS of 3.2 [1.8-4.6] versus 1.8 [1.2-2.5] (p = 0.05) in patients who received ropivacaine. In addition, patients who received levobupivacaine showed a punctuation in Bromage scale of 0.0 [0.0-1.0] versus 0.0 [0.0-0.0] (p = 0.04) in patients who received ropivacaine. Finally, the parturient who received levobupivacaine scored a mean satisfaction index of 8.1 [7.3-8.9] versus 9.3 [8.7-9.8] (p = 0.02) in those who received ropivacaine. We did not register maternal nor neonate adverse events. CONCLUSION Both infusions (levobupivacaine 0.0625% + fentanyl 2mcg/mL and ropivacaine 0.075% + fentanyl 2mcg/mL) are effective for labor analgesia. However, ropivacaine would present a better pharmacodynamic profile with less motor blockade and decreased need for analgesic rescue hence improving patient's satisfaction.

Abstract
BACKGROUND Various approaches using epidural analgesia have been employed for relieving labor pain and promoting spontaneous delivery. We aimed to evaluate the effect of nalbuphine and ropivacaine versus fentanyl and ropivacaine on the duration of delivery in parturients. METHODS Clinical data of 160 full-term primiparous women who received either nalbuphine or fentanyl in combination with ropivacaine infusion for epidural labor analgesia in our hospital from December 2020 to May 2022 were retrospectively analyzed. The participants were divided into two groups based on anesthesia methods: nalbuphine group (NR group, n = 78) received 0.2 mg/mL nalbuphine combined with 0.1% ropivacaine hydrochloride for patient-controlled epidural analgesia (PCEA) and fentanyl group (FR group, n = 82) received 2 ug/mL fentanyl citrate and 0.1% ropivacaine hydrochloride for PCEA. Both groups received an epidural blockade for labor analgesia at lumbar 2-3 interspace. The duration of the first, second, and third stages of labor, the onset of analgesia, and time before delivery (T0), 15 min of analgesia (T1), 30 min of analgesia (T2), full opening of the uterine opening (T3),exerts force during childbirth(T4), heart rate (HR), blood pressure (BP), blood saturation (SpO2), visual analogue pain scale (VAS) score, Ramsay sedation score, and modified Bromage score, and 5 min were recorded at 2 h postpartum (T5). The neonatal Apgar score, neonatal behavioral neurological assessment (NBNA) score, maternal nausea, vomiting, and itchy skin were recorded. RESULTS Compared with the FR group, the first stage of labor duration (p < 0.05) and total duration of labor (p < 0.05) were shortened and the onset of analgesia (p < 0.05) was increased in the NR group. NR group had lower incidence of urinary retention than FR group (p < 0.05). The maternal and neonatal investigational parameters and scores had no significant difference between the two groups. CONCLUSIONS Nalbuphine combined with ropivacaine in epidural block labor has a faster onset of analgesia and has a lower incidence of urinary retention than fentanyl combined with ropivacaine, and nalbuphine shortens the duration of the first and total stages of labor. Both nalbuphine and fentanyl can reduce pain during labor, have little effect on maternal hemodynamics, and have no significant effect on neonatal Apgar or NBNA scores.

Abstract
BACKGROUND Dexmedetomidine, a potent and highly selective α2-adrenoreceptor agonist has become a popular adjuvant to local anesthetics. The study was designed to explore the effect of dexmedetomidine added to ropivacaine for interscalene brachial plexus block (IBPB) on postoperative analgesia in patients undergoing arthroscopic shoulder surgery. METHODS Forty-four adult patients undergoing arthroscopic shoulder surgery were randomly divided into 2 groups. Group R received 0.25% ropivacaine alone, whereas group RD received 0.25% ropivacaine and 0.5 μg/kg dexmedetomidine. A total volume of 15 ml was administered for ultrasound-guided IBPB in both groups. Duration of analgesia, visual analog scale (VAS) pain score, frequency of PCA pressed, first time of PCA pressed, sufentanil consumption, and patient satisfaction with analgesia quality were recorded. RESULTS Compared with group R, the duration of analgesia was prolonged (8.25±1.76 vs. 11.55±2.41 h; P<0.05), the VAS pain scores were decreased at 8 and 10 h postoperatively (3 (2-3) vs. 0 (0-0) and 2 (2-3) vs. 0 (0-2.25), respectively; P<0.05), the frequencies of PCA pressed were decreased at 4-8 and 8-12 h time intervals (0 (0-0.25) vs. 0 (0-0) and 5 (1.75-6) vs. 0 (0-2), respectively; P<0.05), the time of first PCA pressed was prolonged (9.27±1.85 vs. 12.98±2.35 h; P<0.05), the total 24h sufentanil consumption was reduced (108.72±15.92 vs. 94.65±12.47 μg; P<0.05 ) and patient satisfaction score was also improved (3 (3-4) vs. 4 (4-5); P<0.05) in group RD. CONCLUSION We concluded that adding 0.5 μg/kg dexmedetomidine to 0.25% ropivacaine for IBPB provided better postoperative analgesia, decreased the sufentanil consumption and improved the patient's satisfaction in patients undergoing arthroscopic shoulder surgery.

Abstract
The objective of this research was to modify the crystal shape and size of poorly water-soluble drug ropivacaine, and to reveal the effects of polymeric additive and ultrasound on crystal nucleation and growth. Ropivacaine often grow as needle-like crystals extended along the a-axis and the shape was hardly controllable by altering solvent types and operating conditions for the crystallization process. We found that ropivacaine crystallized as block-like crystals when polyvinylpyrrolidone (PVP) was used. The control over crystal morphology by the additive was related to crystallization temperature, solute concentration, additive concentration, and molecular weight. SEM and AFM analyses were performed providing insights into crystal growth pattern and cavities on the surface induced by the polymeric additive. In ultrasound-assisted crystallization, the impacts of ultrasonic time, ultrasonic power, and additive concentration were investigated. The particles precipitated at extended ultrasonic time exhibited plate-like crystals with shorter aspect ratio. Combined use of polymeric additive and ultrasound led to rice-shaped crystals, which the average particle size was further decreased. The induction time measurement and single crystal growth experiments were carried out. The results suggested that PVP worked as strong nucleation and growth inhibitor. Molecular dynamics simulation was performed to explore the action mechanism of the polymer. The interaction energies between PVP and crystal faces were calculated, and mobility of the additive with different chain length in crystal-solution system was evaluated by mean square displacement. Based on the study, a possible mechanism for the morphological evolution of ropivacaine crystals assisted by PVP and ultrasound was proposed.

Abstract
Context The type of anesthesia in cesarean section can affect the mother and baby. This study aimed to determine the comparative effect of intrathecal hyperbaric bupivacaine vs. hyperbaric ropivacaine on maternal and neonatal outcomes after cesarean section. Evidence Acquisition PubMed, Web of Science, Embase, Google Scholar, IranDoc, MagIran, and Scopus databases were searched from 1 September 2022 to 1 November 2022. Eighteen clinical trials with 1542 patients were included in the analysis. Results There was no statistically significant difference in hypotension, bradycardia, and Apgar score between the 2 groups (P > 0.05). The risk of nausea (relative risk (RR), 1.526; 95% CI, 1.175 - 1.981; P = 0.001) and vomiting (RR, 1.542; 95% CI, 1.048 - 2.268; P = 0.02) caused by bupivacaine was 0.53% and 0.54% higher than that of ropivacaine. The incidence of shivering (RR, 2.24; 95% CI, 1.480 - 3.39; P = 0.00) was 2.24 times higher in the bupivacaine group than in the ropivacaine group. The average onset time of sensory block (standardized mean difference (SMD), -0.550; 95% CI, -1.054 to -0.045; P = 0.032) and motor block (SMD, -0.812; 95% CI, -1.254 to -0.371; P = 0.000) was significantly lower in the bupivacaine group than in the ropivacaine group. Conclusions Despite the fact that ropivacaine and bupivacaine are effective in cesarean section, ropivacaine is more favorable because of less hemodynamic changes, less duration of sensory and motor block, and fewer side effects, which are effective in patient recovery.

Abstract
OBJECTIVE Patellar dislocation is a common injury in sports medicine. While surgical treatment is an important option, pain is severe after surgery. This study compared the analgesic effect and early rehabilitation quality between adductor canal block combined with general analgesia (ACB + GA) and single general analgesia (SGA) after recurrent patellar dislocation (RPD) for "3-in-1" procedure surgery. METHODS From July 2018 to January 2020, a prospective randomized controlled trial was conducted in analgesia management after RPD for "3-in-1" procedure surgery. The 40 patients in the experimental group received ACB (0.3% ropivacaine 30 mL) + GA, while the 38 patients in the control group received SGA. Patients in both groups received "3-in-1" procedure surgery, standardized anesthesia, and analgesia during hospitalization. The outcomes included the visual analog scale (VAS), quadriceps strength, Inpatient Satisfaction Questionnaire (IPSQ), Lysholm scores, and Kujala scores. Total rescue analgesic consumption and adverse events were also recorded. One-way analysis of variance (ANOVA) was used to compare continuous variables between groups and chi-square or Fisher's exact tests were used to compare count data. Nonparametric Kruskal-Wallis H tests evaluated ranked data. RESULTS No significant differences in resting VAS scores were observed at 8, 12, and 24 h postoperatively. However, the flexion and moving VAS scores of the ACB + GA group were significantly lower than those of the SGA group (p < 0.05). Meanwhile, the first triggering of rescue analgesics was advanced in the SGA group (p < 0.0001), and the dose of opioid analgesics was significantly higher (p < 0.0001). The quadriceps strength of the ACB + GA group was higher than that of the SGA group at 8 h postoperatively. The IPSQ of the ACB + GA group was significantly higher 24 h postoperatively. We observed no significant differences in Lysholm and Kujala scores between the two groups at 3 months after surgery. CONCLUSIONS Early analgesia management of ACB + GA showed excellent analgesia effectiveness and a positive hospitalization experience for RPD patients undergoing "3-in-1" procedure surgery. Moreover, this management was good for early rehabilitation.

Abstract
The objective of the study is to improve the results of patients undergoing lumbar spine surgery who are at high risk for anesthesia and/or surgical complications. Two independent groups were compared: the study group (SG, n = 40) (standardized neuroanesthetic protocol with multimodal analgesia) and the control group (CG, n = 40) (intravenous anesthesia based on propofol and fentanyl). The data were collected using prospective observation of early and long-term results of lumbar fusion. After 24 months, the level of functional state and quality of life were studied. Patients in the SG did not have statistically significant changes in intraoperative hemodynamics; the best indicators of cognitive functions were noted. The effectiveness of the SG compared with the CG was confirmed by a statistically significantly lower amount of perioperative opioid drugs required (p = 0.01) and a minimal level of incisional pain (p < 0.05). An intergroup comparison of the adverse effects of anesthesia revealed a significantly lower number in the SG (n = 4) compared to the CG (n = 16) (p = 0.004). The number of postoperative surgical complications was comparable (p = 0.72). Intergroup comparison showed improved ODI, SF-36, and the Macnab scale at 24 months after surgery in the SG compared to the CG (p < 0.05). Long-term clinical results correlated with the level of incisional pain in the first three postoperative days. Our standardized neuroanesthetic protocol ensured effective treatment of postoperative incisional pain, significantly decreased the perioperative use of opioids, reduced adverse anesthesia events, and improved long-term clinical results in patients with high risk factors for anesthetic complications who undergoing open lumbar spine surgery.

Abstract
BACKGROUND Sedation of ventilated critically ill trauma patients requires high doses of opioids and hypnotics. We aimed to compare the consumption of opioids and hypnotics, and patient outcomes using sedation with or without continuous regional analgesia (CRA). METHODS Multiple trauma-ventilated patients were included. The patients were randomized to receive an intravenous analgesia (control group) or an addition of CRA within 24h of admission. A traumatic brain injury (TBI) patients group was analyzed. The primary endpoint was the cumulative consumption of sufentanil at 2 days of admission. Secondary endpoints were cumulative and daily consumption of sufentanil and midazolam, duration of mechanical ventilation, intensive care unit (ICU) stay, and safety of CRA management. RESULTS Seventy six patients were analyzed: 40 (67.5% males) in the control group and 36 (72% males) in the CRA group, respectively. The median [IQR] Injury Severity Score was 30.5 [23.5-38.5] and 26.0 [22.0-41.0]. The consumption of sufentanil at 48h was 725 [465-960] μg/48h versus 670 [510-940] μg/48h (p = 0.16). Daily consumption did not differ between the groups except on day 1 when consumption of sufentanil was 360 [270-480] μg vs. 480 [352-535] μg (p = 0.03). Consumptions of midazolam did not differ between the groups. No difference was noted between the groups according to the secondary endpoints. CONCLUSIONS CRA does not decrease significantly sufentanil and midazolam consumption within the first 5 days after ICU admission in multiple trauma-ventilated patients. The use of peripheral nerve blocks in heavily sedated and ventilated trauma patients in the ICU seems safe.

Abstract
BACKGROUND Hip arthroplasty is effective in treating hip diseases, such as osteoarthritis and hip fracture, but it often brings severe trauma and pain. In recent years, ultrasound-guided supra-inguinal fascia iliaca compartment block(S-FICB) has become a widely used nerve block method for analgesia in hip arthroplasty. METHODS Fifty-three patients preparing for hip arthroplasty were prospectively enrolled. S-FICB was performed under ultrasound guidance, and inject 0.33% ropivacaine into the space. Using the biased-coin design (BCD) sequential allocation method. The initial volume of 0.33% ropivacaine was 30ml. In case of failure, the next patient received a higher volume (defined as the previous volume with an increment of 1.2 mL). If the previous patient had a successful block, the next patient was randomized to a lower volume (defined as the previous volume with a decrement of 1.2 mL), with a probability of b = 0.05, or the same volume, with a probability of 1 - b = 0.95. The study was stopped when 45 successful blocks were achieved. RESULTS Forty-five patients (84.9%) were blocked successfully. The 95% effective volume (EV95) was 34.06ml (95%CI 33.35 ~ 36.28ml). There were 31 patients with non-fracture in this study. The quadriceps muscle strength decreased in only two patients. Moreover, they both received 34.8ml of ropivacaine for S-FICB. Twenty-two patients had hip fractures. There were 3 patients (14%) with failed blocks and 19 patients (86%) with successful blocks. However, all fracture patients experienced less pain after S-FICB. CONCLUSION EV95 of 0.33% ropivacaine for ultrasound-guided S-FICB was 34.06ml. TRIAL REGISTRATION The trial was registered at the Chinese Clinical Trial Registry (registration number: ChiCTR2100052214, registration date: 2021 October 22).

Abstract
Background The role of the sympathetic nervous system appears to be central in causing pain in complex regional pain syndrome (CRPS). The stellate ganglion block (SGB) using additives with local anesthetics is an established treatment modality. However, literature is sparse in support of selective benefits of different additives for SGB. Hence, the authors aimed to compare the efficacy and safety of clonidine with methylprednisolone as additives to ropivacaine in the SGB for treatment of CRPS. Methods A prospective randomized single blinded study (the investigator blinded to the study groups) was conducted among patients with CRPS-I of the upper limb, aged 18-70 years with American Society of Anaesthesiologists physical status I-III. Clonidine (15 μg) and methylprednisolone (40 mg) were compared as additives to 0.25% ropivacaine (5 mL) for SGB. After medical treatment for two weeks, patients in each of the two groups were given seven ultrasound guided SGBs on alternate days. Results There was no significant difference between the two groups with respect to visual analogue scale score, edema, or overall patient satisfaction. After 1.5 months follow-up, however, the group that received methylprednisolone had better improvement in range of motion. No significant side effects were seen with either drug. Conclusions The use of additives, both methylprednisolone and clonidine, is safe and effective for the SGB in CRPS. The significantly better improvement in joint mobility with methylprednisolone suggests that it should be considered promising as an additive to local anaesthetics when joint mobility is the concern.

Abstract
OBJECTIVE To determine the median effective dose (ED50) and the 95% effective dose (ED95) of 0.2% ropivacaine for ultrasound-guided lower forearm median nerve block in paediatric patients. METHODS Eligible children were American Society of Anesthesiologists (ASA) status I-II scheduled to have elective open surgery for trigger thumb repair. Patients were stratified into two age groups: 1- to 3-year-olds and 3- to 6-year-olds. The ED50 was determined by Dixon's up-and-down method. The first patient received an ultrasound-guided median nerve block by injection of 2 mL of 0.2% ropivacaine. Each subsequent patient's dose was determined by the response of the previous patient, the doses being adjusted in intervals of 0.2 mL. In addition, the 95% effective dose (ED95) was obtained using a probit regression approach. The patients' general condition, postoperative pain scores, and adverse events were recorded. RESULTS A total of 52 children who were scheduled to undergo open surgery for trigger thumb were included in this study: 28 in the 1- to 3-year-olds group and 24 in the 3- to 6-year-olds group. The ED50 (95% confidence interval) values were 0.9 (0.44-1.36) mL in 1- to 3-year-olds and 1.4 (1.14-1.66) mL in 3- to 6-year-olds. The ED95 (95% confidence interval) values were 1.5 (0.98-1.58) mL in 1- to 3-year-olds and 1.7 (1.54-1.78) mL in 3- to 6-year-olds. No adverse events occurred. CONCLUSIONS A single dose of ropivacaine was an effective agent for young children requiring ultrasound-guided lower forearm median nerve block in open surgery for trigger thumb. The ED50 (95% confidence interval) values were 0.9 (0.44-1.36) mL in 1- to 3-year-olds and 1.4 (1.14-1.66) mL in 3- to 6-year-olds. The ED95 (95% confidence interval) values were 1.5 (0.98-1.58) mL in 1- to 3-year-olds and 1.7 (1.54-1.78) mL in 3- to 6-year-olds.

Abstract
Etomidate is an ultra-short-acting anesthetic agent derived from imidazole that can only be administered intravenously. Etomidate has excellent hemodynamic properties in inducing anesthesia, making it an ideal choice for patients with shock, hypovolemia, or significant cardiovascular disease, with minimal reduction in blood pressure. We report a case of a female patient who was given accidental etomidate intrathecally instead of ropivacaine because of its similar appearance, which led to a slight decrease in blood pressure and no change in the pulse rate. The patient had stable vital signs and no neurological complications.
