Peripheral Nerve Blockade for Medial Patellofemoral Ligament Reconstruction in Pediatric Patients: The Addition of a Proximal Single-Injection Sciatic Nerve Block Provides Improved Analgesia. Local Reg Anesth 2022; 15:31-43. [PMID: 35782524 PMCID: PMC9249091 DOI: 10.2147/lra.s360738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 06/10/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose We tested the hypothesis that the addition of a single-injection proximal sciatic nerve block to an adductor canal block would significantly reduce pain scores and opioid requirements compared to a group of patients that received only an adductor canal or femoral nerve block for medial patellofemoral ligament reconstruction in pediatric patients. The primary end-point is the number of patients achieving a Patient Acceptable Symptom State (PASS) (pain score less than four) for the entire 24-hour postoperative period in patients with and without a proximal sciatic block. Patients and Methods This is a retrospective cohort study of 144 consecutive pediatric patients, ages 10 to 18 years, undergoing medial patellofemoral ligament reconstruction with peripheral nerve blockade for postoperative analgesia from 2016–2020 at a pediatric orthopedics children’s hospital. Patients were divided into 2 cohorts with and without a proximal sciatic nerve block: group A/F: adductor canal or femoral CPNB and group AS: adductor canal CPNB and a proximal single-injection sciatic nerve block. Results There was strong evidence for an increase in the number of patients who reported a pain score less than four for the entire 24-hour postoperative period in the group that received the additional proximal sciatic block. (PASS: A/F 13/62 (21%) vs AS 43/82 (52%), p<0.001) There was strong evidence for a reduction in mean and maximum pain scores and opioid requirements in the first 24-hours after surgery in the proximal sciatic group. Conclusion The addition of a proximal sciatic nerve block was associated with significantly reduced mean and maximum pain scores and opioid requirements after medial patellofemoral ligament reconstruction in pediatric patients and supports a randomized clinical trial to confirm these findings. Based on the results of this study we recommend the addition of a proximal sciatic nerve block, anterior or posterior, to an adductor canal block to provide improved analgesia and reduced opioid requirements in the 24-hours after MPFLR in pediatric patients.

Dexmedetomidine as an adjunct to peripheral nerve blocks in pediatric patients. World J Pediatr 2022; 18:251-262. [PMID: 35006581 DOI: 10.1007/s12519-021-00507-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 12/16/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Combining local anesthetics with dexmedetomidine (DEX) for nerve blocks has been tested and confirmed as an alternative technique to strengthen analgesia in adults, but the evidence supported this proposal in pediatrics was not convincing enough. Thus, we intend to conduct a meta-analysis to make an appraisal of the effects of DEX as a local anesthetic adjuvant on peripheral nerve blocks in children. METHODS The analysis has been registered on https://www.crd.york.ac.uk/prospero/ with the registration number CRD42021254029 on June 10th, 2021. PubMed, Ovid MEDLINE, Embase and Cochrane central register were searched for the randomized controlled trials (RCTs) that are relevant to child/pain/DEX or block up to April 30, 2021. RESULTS Eight RCTs were included for data analysis. The pooled results showed a significantly reduced number of patients who required postoperative analgesics within DEX groups [odds ratio = 0.1, 95% confidence interval (CI) 0.03-0.32, P < 0.001]. And DEX significantly prolonged the duration of analgesia of local anesthetics in the meantime [standardized mean difference (SMD) = 4.93, 95% CI 3.02-6.83, P < 0.001]. Nevertheless, adding DEX as an adjunct to local anesthetics would significantly decrease heart rate (SMD = - 0.95, 95% CI - 1.45 to - 0.45, P < 0.001) and increase sedation score (SMD = 1.6, 95% CI 0.53-2.66, P = 0.003) simultaneously. CONCLUSIONS Adding DEX as an adjunct to peripheral nerve blocks can prolong analgesia until postoperative 8 hours in pediatric patients. However, the benefits should be weighed against the increasing risk of bradycardia and sedation in critical children.

The addition of clonidine to ropivacaine in rectus sheath nerve blocks for pediatric patients undergoing laparoscopic appendectomy: A double blinded randomized prospective study. J Clin Anesth 2021; 71:110254. [PMID: 33752119 DOI: 10.1016/j.jclinane.2021.110254] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 02/28/2021] [Accepted: 03/02/2021] [Indexed: 11/23/2022]
Abstract
STUDY OBJECTIVE The primary goal of this study was to determine if the addition of clonidine to ropivacaine prolonged periumbilical numbness compared to ropivacaine alone in pediatric patients receiving ultrasound guided rectus sheath nerve blocks for laparoscopic appendectomy. The secondary goals were to evaluate differences in perioperative pain scores, analgesic consumption, sedation, anxiolysis, and hemodynamic effects from clonidine. DESIGN This was a single center, randomized, double-blinded prospective study. SETTING This study was conducted within the pediatric operating rooms at the Children's Hospital of Pittsburgh, a large university-based academic medical center. PATIENTS Fifty pediatric patients (ages 10-17 years old) without pre-existing cognitive impairment, developmental delay or chronic pain undergoing laparoscopic appendectomy during weekday hours were enrolled and randomized to control versus intervention groups. INTERVENTION Ultrasound guided rectus sheath nerve block injections were performed at the beginning of surgery with either ropivacaine 0.5% plus normal saline or ropivacaine 0.5% plus clonidine (2 mcg/kg, maximum of 100 mcg). MEASUREMENTS The duration of periumbilical numbness, Numeric Pain Rating Scale scores, University of Michigan Sedation Scale, State-Trait Anxiety Inventory for Children, analgesic consumption, heart rate, blood pressure, and mean arterial pressures, were recorded for each patient at several time points in the perioperative setting. MAIN RESULTS There were no significant differences in demographic characteristics between groups. The median duration of periumbilical numbness did not significantly differ between the ropivacaine only and the ropivacaine plus clonidine groups 540.0 minutes [360.0 -1015.0] (median [interquartile range (IQR)]) versus 823.5 minutes [509.5- 1080.0], p = 0.451. There were no significant differences in perioperative analgesic consumption, pain and anxiety scores, PACU sedation, or hemodynamic instability. CONCLUSIONS The addition of clonidine did not significantly prolong rectus sheath nerve block duration and was well tolerated in pediatric patients. Perioperative analgesia, hemodynamics, anxiety, and PACU sedation did not differ between groups. TRIAL REGISTRATION Clinical Trials NCT02439281.

Efficacy of caudal vs intravenous administration of α 2 adrenoceptor agonists to prolong analgesia in pediatric caudal block: A systematic review and meta-analysis. Paediatr Anaesth 2020; 30:1322-1330. [PMID: 32978991 DOI: 10.1111/pan.14025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 09/06/2020] [Accepted: 09/15/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND α2 adrenoceptor agonists have been proposed as adjuncts to prolong analgesia in pediatric caudal block. The aim of this meta-analysis was to compare the analgesic efficacy of caudal vs intravenous α2 adrenoceptor agonists during pediatric caudal block. METHODS A systematic search, data extraction, bias risk assessment, and pooled data analysis were performed following the PRISMA guidelines. All randomized controlled trials comparing caudal with intravenous α2 adrenoceptor agonists in pediatric caudal block were included. Relative risk and weighted mean differences (the corresponding 95% confidence intervals) were calculated for dichotomous and continuous data, respectively. Trial sequential analyses were performed to evaluate the credibility of the meta-analysis. RESULTS A total of 244 patients in five trials were identified. Compared with the intravenous group (9.56 ± 4.23 hours), the time to the first rescue analgesia was prolonged in the caudal α2 adrenoceptor agonists group (12.72 ± 5.99 hours) by a weighted mean difference of 2.98 hours [95% confidence interval: 0.59-5.36 hours; P = .01]. The number of children requiring rescue analgesia in the caudal group (64, 66.67%) was lower than that in the intravenous group (80, 81.63%) [relative risk = 0.82; 95% confidence interval: 0.69-0.97; P = .02]. These findings were also verified by trial sequential analysis. There were no significant differences in the side effects. CONCLUSION Caudal α2 adrenoceptor agonists as adjuncts to local anesthetic during pediatric caudal block are more effective than intravenous injection. However, the results were affected by small sample size and significant heterogeneity.

Abstract
Trends in pediatric pain management are moving toward thinking beyond opioids. Regional anesthetic techniques, such as quadratus lumborum and erector spinae plane blocks, demonstrate efficacy and safety in pediatric populations. Extremity blocks with motor-sparing characteristics also are used. Adjuvants may be added to pediatric peripheral nerve blocks to increase duration of action and improve block efficacy. For medical management, pediatric pain management frequently uses nonopioid medications. These opioid-sparing medications and regional techniques are used to facilitate enhanced recovery after surgery in pediatric surgical patients. Virtual reality is a field where technology can aid in managing acute pain in pediatric patients.

Continuous caudal epidural analgesia and early feeding in delayed bladder exstrophy repair: a nine-year experience. J Pediatr Urol 2019; 15:76.e1-76.e8. [PMID: 30600203 DOI: 10.1016/j.jpurol.2018.10.022] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Accepted: 10/27/2018] [Indexed: 01/04/2023]
Abstract
BACKGROUND Children undergoing primary closure of bladder exstrophy experience blood loss and significant fluid shifts and require protracted periods of postoperative immobilization to avoid compromising the repair. Suboptimal anxiolysis and pain management is associated with increased morbidity. There is a lack of consensus on the optimal analgesic technique and studies have not previously described analgesic management in delayed bladder exstrophy closure. In exstrophy management, opioid infusions and benzodiazepine sedation are commonplace but are associated with dose-dependent respiratory and gastrointestinal side-effects. We present nine years of caudal epidural anaesthesia in delayed bladder exstrophy repair and describe its facilitation of early extubation and early feeding (within 12 h) without surgical complication. METHODS We retrospectively evaluated consecutive infants with classic bladder exstrophy undergoing delayed primary closure with anterior pelvic osteotomies between November 2007 and January 2016. Outcomes and complications were evaluated in terms of postoperative comfort (using the FLACC score-Face, Legs, Activity, Cry, Consolability), epidural failure rate, re-intubation rate and gastrointestinal complications. RESULTS Forty-four infants had average age of 5.8 months (range 1.6-17.1 months) and weight of 7.0 kg (range 3.5-11.8 kg), and their duration of surgery was 9.5 h (range 6.9-14.3 h). Forty-two of 44 (95.5%) patients received caudal epidural catheters. At 24 h, 15 of 42 (35.7%) caudal epidurals required supplementation with intravenous opioids. Fewer patients with optimally functioning epidurals required postoperative ventilation (1/27 [3.7%] compared with 3/15 [20.0%]). None of the patients with caudal epidural catheters required re-intubation. Pain scores were lower in infants with isolated caudal epidurals catheters than those with caudal epidurals supplemented by intravenous opioids (day 1 [18 vs 53; P = 0.008]; day 2 [8 vs 15; P > 0.05] and overall [32 vs 65; P = 0.014]). Infants with intravenous opioids experienced higher complications: pruritus (25% [95% confidence interval {CI}: 5%-57%] vs 0% [95% CI: 0%-13%]; P = 0.026) and nausea and vomiting (25% [95% CI: 5%-57%] vs 8% [95% CI: 1%-25%]; P = 0.30) requiring treatment. Nineteen of 44 (43.1%) infants were fed early (within 12 h of surgery). Infants who were fed early had lower pain scores than infants feeding late (day 1 [17.5 vs 31; P > 0.05]; day 2 [5.5 vs 15; P = 0.045]; overall [26 vs 55.5; P = 0.015]) without increase in complications (nausea and vomiting [6.3% vs 20.0%; P = 0.06]; ileus [0.0% vs 0.0%]; aspiration [0.0% vs 0.0%] and re-intubation aspiration [0.0% vs 0.0%]). CONCLUSIONS Caudal epidural analgesia facilitates postoperative extubation in infants undergoing delayed exstrophy repair. Early feeding (within the first 12 h) in delayed bladder exstrophy repair is likely to improve patient comfort and consolability without increasing the incidence of gastrointestinal complications. Intravenous opioid may be associated with increased postoperative complications that may influence peri-operative outcomes.

Abstract
BACKGROUND Cryoanalgesia prevents pain by freezing the affected peripheral nerve. We report the use of intraoperative cryoanalgesia during the Nuss procedure for pectus excavatum and describe our initial experience, modifications of technique, and lessons learned. MATERIALS AND METHODS We retrospectively reviewed the medical records of patients who received cryoanalgesia during the Nuss procedure between June 1, 2015, and April 30, 2016, at our institutions and analyzed modifications in surgical technique during this early adoption period. RESULTS Eight male and two female patients underwent the Nuss procedure with cryoanalgesia. The mean postoperative length of stay (LOS) was 2days (range 1-3). Average inpatient pain scores were 3.4, 3.2, and 4.6 on postoperative days 1-3, respectively (N=10, 7, and 2). At a 1-week postoperative visit, mean pain score was 1.1 (N=6). Compared to the preceding 15 Nuss patients at our institution, who were treated with a thoracic epidural, postoperative LOS was significantly shorter with cryoanalgesia (2.0±0.82 vs. 6.3±1.3days, P<0.001). We modified our technique for patient habitus and adopted single-lung ventilation for improved visualization. CONCLUSIONS Cryoanalgesia may be the ideal pain management strategy for Nuss patients because it is effective and long lasting. Intraoperative application is easily integrated into the Nuss procedure. STUDY TYPE Treatment study: case series; Evidence level IV.

Abstract
The aims of this study were to develop a population pharmacokinetic model of sufentanil coadministered with 0.2% ropivacaine as an epidural infusion in infants and describe the sufentanil absorption profile from epidural space. Data from 2 previously published studies were merged for analysis-20 infants aged 3-36 months receiving sufentanil as an epidural infusion and 41 children 0-17 years old receiving sufentanil as a long-term intravenous infusion. A population nonlinear mixed-effects model was built in NONMEM. Sufentanil pharmacokinetics were described by a 2-compartment model with first-order absorption. The effect of body size on all volume and clearance parameters was included in the model according to allometric scaling with theoretical exponents. The maturation process of metabolic clearance was described by the Hill model. During the model-building process the population was divided into 2 fractions with different typical values of metabolic clearance (CL1 and CL2). The typical values of systemic clearance scaled to a 70-kg patient for the 2 subpopulations were CL1 = 52.6 L/h and CL2 = 158 L/h. The parameters of the Hill function were 54.9 weeks for the postmenstrual age of 50% clearance maturation and 0.802 for the Hill coefficient. The typical values of distribution clearance and volumes of the central and peripheral compartments for a patient with a weight of 70 kg were Q = 40.5 L/h, VC = 7.63 L, and VT = 473 L, respectively. The value of the absorption rate constant from the epidural space was 0.0459/h, which suggests flip-flop pharmacokinetics of sufentanil after epidural administration.

Abstract
PURPOSE OF REVIEW Effective analgesia is necessary for optimal recovery after surgery, but children often do not attain adequate postoperative pain control. This review examines the current trends in paediatric regional anaesthesia. RECENT FINDINGS Better pain assessment and therapeutic regimens are needed for our patients. Trunk blocks such as paravertebral, transversus abdominis plane, rectus sheath and ilioinguinal/iliohypogastric are becoming a popular means of providing analgesia for thoracic and abdominal procedures. The introduction of ultrasound guidance improves accuracy, efficacy, and safety of regional anaesthesia, and also decreases the amount of local anaesthetic injected. Single injection nerve blocks have a limited duration and the patients can benefit from adding an adjunct to local anaesthetic or placing a catheter. The use of adjuncts is reasonable, but it is difficult to find a medication with both minimal side-effects and the ability to combat pain for extended periods of time. More peripheral nerve block catheters are used in the paediatric inpatient and outpatient settings and recent data support the feasibility and efficacy of ambulatory peripheral nerve catheters. SUMMARY By using a multimodal approach that includes regional anaesthesia, paediatric pain management should aim to reduce patients' pain to an acceptable level without compromising their degree of mobilization. Undoubtedly, peripheral nerve blocks improve analgesia, but future large prospective studies should be conducted to further delineate their effectiveness, duration and safety.

Abstract
Pain control during the dental procedure is essentials and challenging. A complete efficacious pulp anesthesia has not been attained yet. The regional anesthesia such as inferior alveolar nerve block (IANB) only does not guarantee the effective anesthesia with patients suffering from irreversible pulpitis. This main aim of this review was to discuss various aspects of intraseptal dental anesthesia and its role significance in pain-free treatment in the dental office. In addition, reasons of failure and limitations of this technique have been highlighted. Literature search was conducted for peer-reviewed articles published in English language in last 30 years. Search words such as dental anesthesia, pain control, intraseptal, and nerve block were entered using a web of knowledge and Google scholar databases. Various dental local anesthesia techniques were reviewed. A combination of block anesthesia, buccal infiltration and intraligamentary injection resulted in deep anesthesia (P = 0.003), and higher success rate compared to IANB. For pain-free management of conditions such as irreversible pulpitis, buccal infiltration (4% articaine), and intraosseous injection (2% lidocaine) are better than intraligamentary and IANB injections. Similarly, nerve block is not always effective for pain-free root canal treatment hence, needing supplemental anesthesia. Intraseptal anesthesia is an efficient and effective technique that can be used in maxillary and mandibular adult dentition. This technique is also beneficial when used in conjunction to the regional block or local dental anesthesia.

Abstract
BACKGROUND Adult meta-analyses have verified that adjunct use of alpha-2 adrenoceptor agonists (A2AA) together with local anesthetics (LA) will prolong the duration of peripheral nerve blocks. The standard use of A2AAs for peripheral nerve blockade has recently been recommended also in children, but the evidence base in support of this suggestion has to date been equivocal. The purpose of this meta-analysis was to produce evidence-based data regarding the effect in children. METHODS Following a thorough literature search, five randomized controlled trials were included in a meta-analysis. Raw data from all studies were gathered and aggregated into patients randomized to receive plain LA (Group PLA) or LA mixed with either adjunct clonidine or dexmedetomidine (Group ADJ). The main outcome parameter was block duration (time to first administration of supplemental analgesic based on predetermined pain scores) analyzed by survival statistics. The total number of supplemental analgesic doses during the first 24 postoperative hours and serious side effects were included as secondary outcomes. RESULTS Pooling of the study data generated 141 patients in Group PLA and 142 patients in Group ADJ (overall n = 283; age: 0.8-13 years; weight 8-47 kg). Block duration was significantly prolonged (9.75 h vs 3.75 h) compared to the use of plain LA. Survival statistics verified a beneficial effect of using adjunct A2AAs [the log rank (Mantel-Cox) test (P = 0.0078), Gehan-Breslow-Wilcoxon test (P = 0.0027), and hazard ratio (1.653; 95% CI: 1.142 to 2.395)]. The number of patients that needed ≥ 2 doses of supplemental analgesics was higher in Group PLA (n = 19) compared to Group ADJ (n = 6) (P = 0.0088). No serious side effects were reported. CONCLUSION This meta-analysis provides evidence-based support for the use of adjunct alpha-2 adrenoceptor agonists when performing peripheral nerve blocks in children.

Abstract
BACKGROUND Adult meta-analysis has identified dexmedetomidine as a potentially useful adjunct to prolong the duration of peripheral nerve blocks. However, no data exist regarding the adjuvant use of dexmedetomidine in the setting of pediatric peripheral nerve blocks. METHODS Using a prospective, randomized, double-blind design, children (1½-8 years, ASA 1-2) scheduled for outpatient inguinal hernia repair were randomized to receive either an ultrasound-guided ilioinguinal/iliohypogastric nerve block (IINB) with plain ropivacaine 0.197% (Group LA; n = 21) or ropivacaine 0.197% with adjunct dexmedetomidine 0.3 μg·kg(-1) (Group LAD; n = 22). The primary endpoint of the study was time to first postoperative administration of supplemental analgesia (FPASA) triggered by a pain score ≥4 (CHIPPS or NRS scale). Intention-to-treat (ITT) analysis was decided as the primary statistical analysis of the data. RESULTS The median time to FPASA was prolonged by 88% following the use of adjunct dexmedetomidine (4.0 and 7.6 h in group LA and LAD, respectively) (P = 0.0717). Patients in Group LA displayed a significantly higher number of patients with a CHIPPS score ≥4 in the PACU (7 vs 0; P = 0.0029) as well as a higher incidence of PAED (4 vs 0; P = 0.0485) when compared to patients in Group LAD. No adverse events were recorded in any of the study groups. CONCLUSIONS The use of dexmedetomidine as an adjunct to an IINB resulted in reduced incidences of CHIPPS pain scores ≥4 and PAED scores of ≥11 during early recovery following pediatric inguinal hernia repair. In addition, the use of adjunct dexmedetomidine was associated with a prolongation of the period to first supplemental analgesia demand. The results of the present exploratory study must be viewed as preliminary and need further validation by future larger sized studies and/or meta-analysis.
