Randomized Controlled Trial
Effects of Ultrasound-Guided Thoracic Paravertebral Nerve Block Combined with Perineural or IV Dexmedetomidine on Acute and Chronic Pain After Thoracoscopic Resection of Lung Lesions: A Double-Blind Randomized Trial.
BACKGROUND
Thoracic paravertebral block (TPVB) analgesia can be prolonged by local anesthetic adjuvants such as dexmedetomidine. This study aimed to evaluate the two administration routes of dexmedetomidine on acute pain and chronic neuropathic pain (NeuP) prevention compared with no dexmedetomidine.
METHODS
A total of 216 patients were randomized to receive TPVB using 0.4% ropivacaine alone (R Group), with perineural dexmedetomidine 0.5 μg·kg (RD Group) or 1.0 μg·kg (RD Group), or intravenous (IV) dexmedetomidine 0.5 μg·kg·h (RD Group). The primary outcome was the incidence of chronic NeuP, defined as a Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain score > 12 points at 3-month after surgery.
RESULTS
(1) For the primary outcome, RD Group and RD Group demonstrated a decreased incidence of chronic NeuP at 3-month after surgery; (2) Compared with R Group, RD Group, RD Group, and RD Group can reduce VAS scores at rest and movement and Prince-Henry Pain scores at 12 and 24-h after surgery, the consumption of oral morphine equivalent (OME) and improve QOD-15 at POD1; (3) Compared with RD Group, RD Group and RD Group can reduce VAS scores at rest and movement and Prince-Henry Pain scores at 12 and 24-h after surgery, the consumption of postoperative OME and improve QOD-15 at POD1; (4) Compared with RD Group, RD Group effectively reduced VAS scores at rest at 12 and 24-h after surgery, VAS scores in movement and Prince-Henry Pain scores at 12-h after surgery. However, RD Group showed an increased incidence of drowsiness.
CONCLUSION
Perineural or IV dexmedetomidine are similarly effective in reducing acute pain, but only perineural dexmedetomidine reduced chronic NeuP. Moreover, considering postoperative complications such as drowsiness, perineural dexmedetomidine (0.5 μg·kg) may be a more appropriate choice.

Randomized Controlled Trial Comparative Study
Comparison of ultrasound-guided rhomboid intercostal and subserratus plane block versus thoracic paravertebral block for analgesia in thoracoscopic surgery: a randomized, controlled, non-inferiority trial.
BACKGROUND
To investigate the non-inferiority of ultrasound-guided rhomboid intercostal and subserratus plane (RISS) block compared to thoracic paravertebral block (TPVB) in postoperative analgesia for thoracoscopic surgeries.
METHODS
This study consecutively enrolled 50 patients undergoing elective thoracoscopic surgery. Following general anesthesia, the RISS group received a unilateral block with 40 mL of 0.25% ropivacaine, while the TPVB group received with 30 mL of 0.33% ropivacaine. The primary outcome measure was the 24-hour postoperative resting VAS score. Secondary outcome measures included nerve block operation time for two groups, postoperative 1, 2, 4, 8, 48-hour resting VAS scores, and different time points coughing VAS scores, time to first postoperative ambulation, total intravenous analgesic consumption at different time points postoperatively, complications related to the block.
RESULTS
There were no significant statistical differences between the two groups in terms of postoperative rest and cough VAS scores at each time (P>0.05), and the mean difference in rest VAS scores did not exceed the non-inferiority margin in 95% CI. There were no significant differences in total intraoperative and postoperative analgesic consumption at different time points (P>0.05), and no significant differences in time to first postoperative ambulation (P>0.05). Compared to the TPVB group, the RISS group had a shorter nerve block operation time (259.43±30.11 vs. 335.23±30.96 s, P<0.001) and fewer instances of intraoperative hypotension (two vs. seven cases, P=0.022), bleeding at the puncture site, pneumothorax, and arrhythmia.
CONCLUSIONS
In thoracoscopic surgeries, the postoperative analgesic efficacy of ultrasound-guided RISS block is not inferior to TPVB. Compared to TPVB, RISS block is simpler, quicker, and associated with fewer puncture-related complications.

Comparison of analgesic effect of pericapsular nerve group block and supra-inguinal fascia iliaca compartment block on dynamic pain in patients with hip fractures: a randomized controlled trial.
BACKGROUND
Patients with hip fracture often experience severe pain, particularly during movement or slight positional change, prior to the occurrence of surgery. It is essential to explore the appropriate analgesic methods before surgery in patients with hip fracture, especially those capable of alleviating dynamic pain. Pericapsular nerve group (PENG) block was introduced as a useful technique for hip analgesia. In this study, we aimed to compare the reduction in dynamic pain between the PENG block and supra-inguinal fascia iliaca compartment block (SIFICB).
METHODS
This prospective trial included 80 hip fracture patients aged ≥19 years, with an American Society of Anesthesiologists Physical Status of 1-4 and a baseline dynamic pain score ≥4 on the numerical rating scale. The patients were randomly allocated into the PENG block (n=40) and SIFICB group (n=40). For the PENG block and SIFICB, 20 mL and 30 mL of 0.3% ropivacaine was used, respectively. The primary outcome was reduction in dynamic pain scores at 30 min following the peripheral nerve block. Dynamic pain score was evaluated when the leg was passively raised.
RESULTS
A total of 79 patients were included in the final analysis, and the reductions in pain score during hip flexion were 3.1±2.4 and 2.9±2.5 in the PENG block and SIFICB groups, respectively, which was statistically insignificant (p=0.75). Moreover, no significant differences were observed in any of the outcomes.
CONCLUSIONS
PENG block and SIFICB could effectively provide analgesia for dynamic pain in patients with hip fractures, with no significant difference between the two groups.

Postoperative care pathways for adolescent idiopathic scoliosis patients undergoing posterior spinal fusion have demonstrated decreases in postoperative opioid consumption, improved pain control, and lead to decreased lengths of stay. Our objective was to implement postoperative steroids to reduce acute postoperative opioid consumption, pain scores, and length of stay. Dosing consisted of intravenous dexamethasone 0.1 mg/kg up to 4 mg per dose for a total of three doses at 8, 16, and 24 h postoperatively. As part of a quality initiative, we compared three cohorts of patients. The initial retrospective epidural cohort (EPI) ( = 59) had surgeon placed epidural catheters with infusion of ropivacaine 0.1% postoperatively for 18-24 h. Following an institutional change in postoperative care, epidural use was discontinued. A second cohort ( = 149), with prospectively collected data, received a surgeon placed erector spinae plane block and wound infiltration with a combination of liposomal and plain bupivacaine (LB). A third cohort ( = 168) was evaluated prospectively. This cohort received a surgeon placed erector spinae plane block and wound infiltration with liposomal and plain bupivacaine and additionally received postoperative dexamethasone for three doses (LB + D). Compared to the LB cohort, the LB + D cohort demonstrated statistically significant decreases in oral milligram morphine equivalents per kilogram at 0-24, 24-48, and 48-72 h. There was a statistically significant difference in median pain scores at 24-48 and 48-72 h in LB + D versus LB. The LB + D cohort's median length of stay in hours was significantly less compared to the LB cohort (52 h vs. 70 h, < 0.0001). Postoperative intravenous dexamethasone was added to an established postoperative care pathway for patients undergoing posterior spinal fusion for idiopathic scoliosis resulting in decreased VAS pain scores, opioid consumption, and shorter length of stay.

BACKGROUND
Patients with a fractured femur experience intense pain during positioning for neuraxial block for definitive surgery. Femoral nerve block (FNB) is therefore often given prior to positioning for analgesia. In our study, we compare the onset and quality of block of 0.25% bupivacaine, 0.5% ropivacaine, and 1.5% lignocaine for FNB in fracture femur patients.
METHODS
Seventy-five adult femur fracture patients were equally and randomly divided into three groups to receive 15 ml of either 0.25% bupivacaine (group B), 0.5% ropivacaine (group R), or 1.5% lignocaine (group L) for FNB prior to positioning for neuraxial blockade. Onset and quality of block were assessed, as well as improvement in visual analog scale (VAS) score, ease of positioning, and patient satisfaction.
RESULTS
Percentage decrease in VAS was found to be highest in group R (82.8%) followed by groups L and B. Time to achieve a VAS of less than 4 was found to be 26.2±2.4 minutes in group B, 8.5±1.9 minutes in group R, and 4.1±0.7 minutes in group L (P<0.001). In group B, 12 patients required additional fentanyl to achieve a VAS <4. Patient positioning was reported to be satisfactory in all patients in group R and L, while in B it was satisfactory in 13 (52%) patients only. Patient acceptance of FNB was 100% in group R and L, but only 64% in group B.
CONCLUSIONS
Based on our findings, 0.5% ropivacaine is a favorable choice for FNB due to early onset, ability to yield a good quality block, and good safety profile.

INTRODUCTION AND IMPORTANCE
Cleft lip and palate (CLP) are congenital anomalies of the craniofacial region, commonly found in low- and middle-income countries, including Indonesia. Surgical correction of clefts typically begins at around three months of age to support infant growth. An infraorbital nerve block is an option for regional anesthesia in CLP surgery. This case series aims to determine the effectiveness of infraorbital nerve block in pain management for pediatric CLP surgery.
CASE PRESENTATION
This case series includes five patients who fulfilled the Millard criteria for CLP surgery. All patients received general anesthesia followed by an infraorbital nerve block with 0.2 % ropivacaine in the infraorbital foramen area using the intraoral approach. Data were collected preoperatively, intraoperatively, and postoperatively.
DISCUSSION
The combination of general anesthesia and infraorbital nerve block resulted in stable hemodynamics, low delirium scores, low pain intensity, and adequate oral intake postoperatively.
CONCLUSION
Infraorbital nerve block with ropivacaine provides intraoperative hemodynamic stability, decreased delirium, and effective postoperative pain management in pediatric patients undergoing CLP surgery.

INTRODUCTION
Although the maxillary nerve block (MNB) provides adequate pain relief in cleft palate surgery, it is not routinely used globally, and reported techniques are heterogeneous. This study aims to describe relevant anatomy and to present the preferred technique of MNB administration based on the current literature and the expert opinion of the authors.
METHOD AND MATERIALS
First, a survey was sent to 432 registrants of the International Cleft Palate Master Course Amsterdam 2023. Second, MEDLINE (PubMed interface) was searched for relevant literature on maxillary artery (MA) anatomy and MNB administration in pediatric patients.
RESULTS
Survey response rate was 18% (n=78). Thirty-five respondents (44.9%) used MNB for cleft palate surgery before the course. A suprazygomatic approach with needle reorientation towards the ipsilateral commissure before incision was most frequently reported, mostly without the use of ultrasound. Ten and 20 articles were included on, respectively, MA anatomy and MNB administration. A 47.5% to 69.4% of the MA's run superficial to the lateral pterygoid muscle and 32% to 52.5% medially. The most frequently described technique for MNB administration is the suprazygomatic approach. Reorientation of the needle towards the anterior aspect of the contralateral tragus appears optimal. Needle reorientation angles do not have to be adjusted for age, unlike needle depth. The preferred anesthetics are either ropivacaine or (levo)bupivacaine, with dexmedetomidine as an adjuvant.
CONCLUSION
Described MNB techniques are heterogeneous throughout the literature and among survey respondents and not routinely used. Further research is required comparing different techniques regarding efficacy and safety.

Randomized Controlled Trial
Analgesic effect of ultrasound-guided transversus abdominis plane block with or without rectus sheath block in laparoscopic cholecystectomy: a randomized, controlled trial.
BACKGROUND
Ultrasound-guided transversus abdominis plane (TAP) block is commonly used for pain control in laparoscopic cholecystectomy. However, significant pain persists, affecting patient recovery and sleep quality on the day of surgery. We compared the analgesic effect of ultrasound-guided TAP block with or without rectus sheath (RS) block in patients undergoing laparoscopic cholecystectomy using the visual analog scale (VAS) scores.
METHODS
The study was registered before patient enrollment at the Clinical Research Information Service (registration number: KCT0006468, 19/08/2021). 88 American Society of Anesthesiologist physical status I-III patients undergoing laparoscopic cholecystectomy were divided into two groups. RS-TAP group received right lateral and right subcostal TAP block, and RS block with 0.2% ropivacaine (30 mL); Bi-TAP group received bilateral and right subcostal TAP block with same amount of ropivacaine. The primary outcome was visual analogue scale (VAS) for 48 h postoperatively. Secondary outcomes included the use of rescue analgesics, cumulative intravenous patient-controlled analgesia (IV-PCA) consumption, patient satisfaction, sleep quality, and incidence of adverse events.
RESULTS
There was no significant difference in VAS score between two groups for 48 h postoperatively. We found no difference between the groups in any of the secondary outcomes: the use of rescue analgesics, consumption of IV-PCA, patient satisfaction with postoperative pain control, sleep quality, and the incidence of postoperative adverse events.
CONCLUSION
Both RS-TAP and Bi-TAP blocks provided clinically acceptable pain control in patients undergoing laparoscopic cholecystectomy, although there was no significant difference between two combination blocks in postoperative analgesia or sleep quality.

Analgesic effects of ultrasound-guided preoperative posterior Quadratus Lumborum block in laparoscopic hepatectomy: A prospective double-blinded randomized controlled trial.
STUDY OBJECTIVE
To determine if single-injection bilateral posterior quadratus lumborum block (QLB) with ropivacaine would improve postoperative analgesia in the first 24 h after laparoscopic hepatectomy, compared with 0.9% saline.
DESIGN
Prospective, double blinded, randomized controlled trial.
SETTING
A single tertiary care center from November 2021 and January 2023.
PATIENTS
A total of 94 patients scheduled to undergo laparoscopic hepatectomy due to hepatocellular carcinoma.
INTERVENTIONS
Ninety-four patients were randomized into a QLB group (receiving 20 mL of 0.375% ropivacaine on each side, 150 mg in total) or a control group (receiving 20 mL of 0.9% saline on each side).
MEASUREMENTS
The primary outcome was the cumulative opioid consumption during the initial 24-h post-surgery. Secondary outcomes included pain scores and intraoperative and recovery parameters.
MAIN RESULTS
The mean cumulative opioid consumption during the initial 24-h post-surgery was 30.8 ± 22.4 mg in the QLB group (n = 46) and 34.0 ± 19.4 mg in the control group (n = 46, mean differences: -3.3 mg, 95% confidence interval, -11.9 to 5.4, p = 0.457). The mean resting pain score at 1 h post-surgery was significantly lower in the QLB group than in the control group (5 [4-6.25] vs. 7 [4.75-8], p = 0.035). No significant intergroup differences were observed in the resting or coughing pain scores at other time points or in other secondary outcomes.
CONCLUSIONS
Preoperative bilateral posterior QLB did not reduce cumulative opioid consumption during the first 24 h after laparoscopic hepatectomy.

Medicine Jun 2024In this study, we analyzed whether scalp nerve block with ropivacaine can improve the quality of rehabilitation in patients after meningioma resection. (Randomized Controlled Trial)
Randomized Controlled Trial
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, P < .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 (P < .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.
