RESUMEN
BACKGROUND: Mepivacaine is an intermediate-acting local anesthetic used for spinal anesthesia in adults. Currently, there are no published dosing guidelines for spinal mepivacaine in patients under age 18. AIMS: The purpose of this study is to describe the clinically used doses of mepivacaine by weight and age for orthopedic surgery in pediatrics. METHODS: We performed a retrospective chart review of patients aged 0-18 who received mepivacaine for spinal anesthesia from 2016 to 2022. We performed a secondary analysis for patients aged 0-18 who received spinal anesthesia with bupivacaine or chloroprocaine. RESULTS: The data extraction yielded 3627 single-shot mepivacaine spinals. Patient age ranged from 5 to 18 years. Median dosage in milligrams/kilograms (mg/kg) of mepivacaine was calculated for each age group. Our analysis revealed that dosage in mg/kg decreased by patient age and began to plateau at age 15. Bupivacaine was the most common single-shot spinal agent in patients under age 10. After age 10, mepivacaine was more common. Chloroprocaine began to be used in patients older than 8 years. CONCLUSIONS: We describe mepivacaine dosage as a function of age and weight in patients younger than 18 years. As age and weight increased, a lower dose of mepivacaine per kg was administered for spinal anesthesia.
RESUMEN
Importance: Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures, such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis, and management of this condition is, however, currently lacking. Objective: To fill the practice guidelines void and provide comprehensive information and patient-centric recommendations for preventing, diagnosing, and managing PDPH. Evidence Review: With input from committee members and stakeholders of 6 participating professional societies, 10 review questions that were deemed important for the prevention, diagnosis, and management of PDPH were developed. A literature search for each question was performed in MEDLINE on March 2, 2022. Additional relevant clinical trials, systematic reviews, and research studies published through March 2022 were also considered for practice guideline development and shared with collaborator groups. Each group submitted a structured narrative review along with recommendations that were rated according to the US Preventive Services Task Force grading of evidence. Collaborators were asked to vote anonymously on each recommendation using 2 rounds of a modified Delphi approach. Findings: After 2 rounds of electronic voting by a 21-member multidisciplinary collaborator team, 47 recommendations were generated to provide guidance on the risk factors for and the prevention, diagnosis, and management of PDPH, along with ratings for the strength and certainty of evidence. A 90% to 100% consensus was obtained for almost all recommendations. Several recommendations were rated as having moderate to low certainty. Opportunities for future research were identified. Conclusions and Relevance: Results of this consensus statement suggest that current approaches to the treatment and management of PDPH are not uniform due to the paucity of evidence. The practice guidelines, however, provide a framework for individual clinicians to assess PDPH risk, confirm the diagnosis, and adopt a systematic approach to its management.

INTRODUCTION: Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis or management of this condition is, however, currently lacking. This multisociety guidance aims to fill this void and provide practitioners with comprehensive information and patient-centric recommendations to prevent, diagnose and manage patients with PDPH. METHODS: Based on input from committee members and stakeholders, the committee cochairs developed 10 review questions deemed important for the prevention, diagnosis and management of PDPH. A literature search for each question was performed in MEDLINE (Ovid) on 2 March 2022. The results from each search were imported into separate Covidence projects for deduplication and screening, followed by data extraction. Additional relevant clinical trials, systematic reviews and research studies published through March 2022 were also considered for the development of guidelines and shared with contributors. Each group submitted a structured narrative review along with recommendations graded according to the US Preventative Services Task Force grading of evidence. The interim draft was shared electronically, with each collaborator requested to vote anonymously on each recommendation using two rounds of a modified Delphi approach. RESULTS: Based on contemporary evidence and consensus, the multidisciplinary panel generated 50 recommendations to provide guidance regarding risk factors, prevention, diagnosis and management of PDPH, along with their strength and certainty of evidence. After two rounds of voting, we achieved a high level of consensus for all statements and recommendations. Several recommendations had moderate-to-low certainty of evidence. CONCLUSIONS: These clinical practice guidelines for PDPH provide a framework to improve identification, evaluation and delivery of evidence-based care by physicians performing neuraxial procedures to improve the quality of care and align with patients' interests. Uncertainty remains regarding best practice for the majority of management approaches for PDPH due to the paucity of evidence. Additionally, opportunities for future research are identified.
RESUMEN
BACKGROUND: Tranexamic acid (TXA) reduces rates of blood transfusion for total hip arthroplasty (THA) and total knee arthroplasty (TKA). Although the use of oral TXA rather than intravenous (i.v.) TXA might improve safety and reduce cost, it is not clear whether oral administration is as effective. METHODS: This noninferiority trial randomly assigned consecutive patients undergoing primary THA or TKA under neuraxial anaesthesia to either one preoperative dose of oral TXA or one preoperative dose of i.v. TXA. The primary outcome was calculated blood loss on postoperative day 1. Secondary outcomes were transfusions and complications within 30 days of surgery. RESULTS: Four hundred participants were randomised (200 THA and 200 TKA). The final analysis included 196 THA patients (98 oral, 98 i.v.) and 191 TKA patients (93 oral, 98 i.v.). Oral TXA was non-inferior to i.v. TXA in terms of calculated blood loss for both THA (effect size=-18.2 ml; 95% confidence interval [CI], -113 to 76.3; P<0.001) and TKA (effect size=-79.7 ml; 95% CI, -178.9 to 19.6; P<0.001). One patient in the i.v. TXA group received a postoperative transfusion. Complication rates were similar between the two groups (5/191 [2.6%] oral vs 5/196 [2.6%] i.v.; P=1.00). CONCLUSIONS: Oral TXA can be administered in the preoperative setting before THA or TKA and performs similarly to i.v. TXA with respect to blood loss and transfusion rates. Switching from i.v. to oral TXA in this setting has the potential to improve patient safety and decrease costs.

Background and Aims: The onset of the coronavirus 2019 (COVID-19) pandemic brought together the American Society of Regional Anesthesia and Pain Medicine (ASRA) and the European Society of Regional Anaesthesia and Pain Therapy (ESRA) to release a joint statement on anesthesia use. Their statement included a recommendation to use regional anesthesia whenever possible to mitigate the risk associated with aerosolizing procedures. We sought to examine the utilization of anesthesia in pediatric patients undergoing a surgical procedure for fractures or ligament repairs before and during COVID-19. Methods: Using the Premier Health Database, we retrospectively analyzed pediatric patients undergoing a surgical intervention for fractures or ligament repair before and during COVID-19. We sought to determine if there were differences in anesthesia use among this cohort during the two time periods. Fracture groups included shoulder and clavicle, humerus and elbow, forearm and wrist, hand and finger, pelvis and hip, femur and knee, leg and ankles, and foot and toes. Ligament procedures included surgical intervention for the anterior cruciate ligament and ulnar collateral ligament repair. Results: We identified a total of 5935 patients undergoing a surgical procedure for fractures or ligament repairs before and during COVID-19. After exclusion for unknown anesthesia use, 2,807 patients were included in our cohort with 81.5% (n = 2288) of patients undergoing a procedure under general anesthesia, 6.4% (n = 181) under regional anesthesia, and 12.0% (n = 338) under combined general-regional anesthesia. There did not appear to be a significant difference in the type of anesthesia used before and during COVID-19 (p = 0.052). Conclusions: Our study did not identify a difference in anesthesia use before and during COVID-19 among pediatric patients undergoing a surgical procedure. Further studies should estimate the change in anesthesia used during the time period when elective procedures were resumed.
RESUMEN
OBJECTIVE: Guidelines for opioid prescription post-operatively exist; however, the majority of these are for adults. Nevertheless, opioid risks are present for pediatric patients also. This study investigates the effect of a single institution's guidelines on post-operative opioid prescribing for pediatric orthopedic patients undergoing knee surgery. We hypothesized that a standardized set of prescribing guidelines would result in a decrease in opioids prescribed at discharge home after these surgeries. DESIGN: Retrospective observational. SETTING: Urban, tertiary care, academic orthopedic hospital. PATIENTS: Pediatric, sports knee surgery, 23-month period. INTERVENTIONS: Guidelines were implemented institutionally for post-operative opioid prescribing practices. We reviewed all post-operative opioid prescriptions for pediatric patients undergoing sports knee surgery with two pediatric sports surgeons for the 11 months prior to the guidelines and 12 months afterwards, totaling 316 surgeries. MAIN OUTCOME MEASURE: Oral morphine equivalents (OMEs) prescribed on discharge from the hospital before and after implementation of guidelines. RESULTS: There was a significant reduction in OMEs from 229 OMEs to 175 OMEs before and after opioid prescribing guidelines (p < 0.001). This is a decrease in approximately seven 5 mg oxycodone tablets per patient. CONCLUSIONS: This study demonstrates that at our institution, with a pediatric patient population having sports knee surgery, prescribing guidelines reduced the number of opioids prescribed at discharge.

OBJECTIVE: To determine the number of opioid pills remaining after pediatric ambulatory knee surgery to provide insight into how many pills are actually used. DESIGN: Prospective observational cohort study. Participants who were expected to be prescribed 20 (Group 1) versus 40 (Group 2) opioid pills according to the institutional policy (based on the type of surgery) were studied. Patient's reported pain, medication use, and number of opioid pills remaining at post-operative days (PODs) 7 and 14. Participants were not randomly assigned to groups and no intervention was applied. SETTING: An urban tertiary care musculoskeletal institution. PARTICIPANTS: Sixty adolescents between the ages of 12 and 19 undergoing ambulatory knee surgery. INTERVENTIONS: Observational study, no experimental study intervention. MAIN OUTCOME MEASURE: The total number of opioid pills remaining. RESULTS: By POD7, more than 70 percent of patients had stopped taking their prescribed opioid medication mainly because their knee pain was tolerable either without the opioid or by using other medications. By POD14, the mean number of pills taken was 6.3 ± 5.3 for Group 1 and 18.4 ± 13.9 for Group 2. The mean number of unused opioids was 13.5 ± 7.2 for Group 1 and 17.9 ± 13.7 for Group 2. CONCLUSIONS: Even with prescribing practice guidelines in place, opioids may be overprescribed and could be given in a smaller quantity without affecting the quality of acute postoperative pain control in adolescents undergoing ambulatory knee surgery. However, one needs to consider that some patients may need a larger than average amount in order to be appropriately treated for their level of pain and thus prescription amounts-preferably after reevaluation-should be individualized.

BACKGROUND: The opioid epidemic is one of the most pressing public health crises in the USA. With fractures being amongst the most common reasons for a child to require surgical intervention and receive post-surgical pain management, characterisation of opioid prescription patterns and risk factors is critical. We hypothesised that the numbers of paediatric patients receiving opioids, or who developed persistent opioid use, are significant, and a number of risk factors for persistent opioid use could be identified. METHODS: We conducted a retrospective population-based cohort study. National claims data from the Truven Health Analytics® MarketScan database were used to (i) characterise opioid prescription patterns and (ii) describe the epidemiology and risk factors for single use and persistent use of opioids amongst paediatric patients who underwent surgical intervention for fracture treatment. RESULTS: Amongst 303 335 patients, 21.5% received at least one opioid prescription within 6 months after surgery, and 1671 (0.6%) developed persistent opioid use. Risk factors for persistent opioid use include older age; female sex; lower extremity trauma; surgeries involving the spine, rib cage, or head; closed fracture treatment; earlier surgery years; previous use of opioid; and higher comorbidity burden. CONCLUSIONS: Amongst a cohort of paediatric patients who underwent surgical fracture treatment, 21.5% filled at least one opioid prescription, and 0.6% (N=1671) filled at least one more opioid prescription between 3 and 6 months after surgery. Understanding risk factors related to persistent opioid use can help clinicians devise strategies to counter the development of persistent opioid use for paediatric patients.

BACKGROUND: The use of regional anesthesia (RA) in pediatric patients remains understudied, although evidence suggests benefits over general anesthesia. QUESTIONS/PURPOSES: We sought to identify factors associated with RA use in patients under the age of 21 years undergoing ambulatory orthopedic surgery. METHODS: Patients under the age of 21 who underwent anterior cruciate ligament (ACL) repair or reconstruction, knee arthroscopy (KA), or shoulder arthroscopy (SA) were identified from the NY Statewide Planning and Research Cooperative System (SPARCS) database (2005-2015). Frequencies of RA use (defined by femoral nerve block, spinal, epidural, caudal, or brachial plexus anesthesia) were calculated. Multivariable regression analysis identified patient- and healthcare system-related factors associated with the use of RA. Odds ratios (OR) and 95% confidence intervals (CI) were reported. RESULTS: We identified 87,273 patients who underwent the procedures of interest (ACL n = 28,226; SA n = 18,155; KA n = 40,892). In our primary analysis, 14.4% (n = 1404) had RA as their primary anesthetic; this percentage increased for patients who had ACL or KA. When adjusting for covariates, Hispanic ethnicity (OR 0.78; CI 0.65-0.94) and Medicaid insurance (OR 0.75; CI 0.65-0.87) were associated with decreased odds for the provision of RA. Further, we identified increasing age (OR 1.10; CI 1.08-1.11), ACL versus SA (OR 1.91; CI 1.74-2.10), and sports injuries (OR 1.20; CI 1.10-1.31) as factors associated with increased odds of RA use. CONCLUSION: In this analysis, RA was used in a minority of patients under the age of 21 undergoing ambulatory orthopedic surgery. Older age was associated with increased use while Hispanic ethnicity and lower socioeconomic status were associated with lower use.
RESUMEN
AIMS: Tranexamic acid (TXA) has been shown to reduce blood loss and transfusion requirements in patients undergoing orthopaedic surgery. There remains a lack of prospective evidence for the use of TXA in patients undergoing periacetabular osteotomy (PAO). The purpose of this study was to determine if intravenous (IV) TXA is effective in reducing calculated blood loss and transfusions after PAO. METHODS: This was a single-centre prospective double-blind placebo-controlled randomized trial of 81 patients aged 12 to 45 years undergoing elective PAO by a single surgeon. The intervention group (n = 40) received two doses of IV TXA of a maximum 1 g in each dose; the control group (n = 41) received two doses of 50 ml 0.9% saline IV. The primary outcome was perioperative calculated blood loss. Secondary outcomes included allogenic transfusions and six-week postoperative complications. RESULTS: There were no differences in demographics or intraoperative variables between study groups. The TXA group demonstrated lower mean calculated blood loss (1,265 ml, (SD 321) vs 1,515 ml, (SD 394); p = 0.002) and lower frequency of allogenic transfusion (10%/n = 4 vs 37%/n = 15; p = 0.008). Regression analyses associated TXA use with significant reductions in calculated blood loss (p < 0.001) and transfusion (p = 0.007) after adjusting for age, sex, body mass index, preoperative haemoglobin, cell-saver volume, intraoperative mean arterial blood pressure, and operating time. No patients suffered venous thromboembolic complications. CONCLUSION: In this trial, IV TXA decreased postoperative calculated blood loss by 293 ml and reduced the frequency of allogenic transfusions by 73% (37% vs 10%) following PAO. TXA may be safe and effective for reducing blood loss in patients undergoing PAO. Cite this article: Bone Joint J 2020;102-B(9):1151-1157.

BACKGROUND: Although surgery represents the only definitive treatment for congenital scoliosis, comprehensive information regarding trends in perioperative complications, particularly in the pediatric setting, is lacking. We sought to identify trends in and factors associated with perioperative complications following pediatric scoliosis surgery. METHODS: In this retrospective cohort study, patients below the age of 21 years undergoing a scoliosis repair procedure were identified from the Premier Healthcare database (2006-2016). The primary outcomes of interest were any complication, cardiopulmonary complications, blood transfusions, intensive care unit (ICU) admission, length of stay (LOS), and cost of hospitalization. Trends in these outcomes over time were analyzed. Multivariable logistic regression models were run to identify factors associated with each of the perioperative outcomes. RESULTS: In the full cohort of 9351 scoliosis patients, 17% experienced any complication, 12% of which were cardiopulmonary in nature, 42% required blood transfusions, and 62% were admitted to the ICU. Median LOS was 5 days (interquartile range [IQR], 4-6) and median cost was $56,375 (IQR, $40,053-$76,311). Annual incidence of complications and blood transfusions as well as LOS and cost decreased significantly throughout the study period. The most consistently observed factors associated with complications were younger age, high comorbidity burden, low institutional case volume, and hospital teaching status. CONCLUSIONS: Although the incidence of the studied adverse outcomes in scoliosis surgery has decreased over time, this study shows it remains relatively high (17%). The associations demonstrated help clarify factors associated with complications and may be useful in guiding interventions to improve outcomes.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complications in pediatric regional anesthesia are rare, so a large sample size is necessary to quantify risk. The Pediatric Regional Anesthesia Network contains data on more than 100,000 blocks administered at more than 20 children's hospitals. This study analyzed the risk of major complications associated with regional anesthesia in children. METHODS: This is a prospective, observational study of routine clinical practice. Data were collected on every regional block placed by an anesthesiologist at participating institutions and were uploaded to a secure database. The data were audited at multiple points for accuracy. RESULTS: There were no permanent neurologic deficits reported (95% CI, 0 to 0.4:10,000). The risk of transient neurologic deficit was 2.4:10,000 (95% CI, 1.6 to 3.6:10,000) and was not different between peripheral and neuraxial blocks. The risk of severe local anesthetic systemic toxicity was 0.76:10,000 (95% CI, 0.3 to 1.6:10,000); the majority of cases occurred in infants. There was one epidural abscess reported (0.76:10,000, 95% CI, 0 to 4.8:10,000). The incidence of cutaneous infections was 0.5% (53:10,000, 95% CI, 43 to 64:10,000). There were no hematomas associated with neuraxial catheters (95% CI, 0 to 3.5:10,000), but one epidural hematoma occurred with a paravertebral catheter. No additional risk was observed with placing blocks under general anesthesia. The most common adverse events were benign catheter-related failures (4%). CONCLUSIONS: The data from this study demonstrate a level of safety in pediatric regional anesthesia that is comparable to adult practice and confirms the safety of placing blocks under general anesthesia in children.

BACKGROUND: The incidence of post-dural puncture headache (PDPH) arising from spinal anesthesia in the general population is low. However, patients under 45 years have been shown to exhibit a higher incidence of PDPH, even with small needles. QUESTIONS/PURPOSES: This study aimed to estimate the incidence of PDPH from a 27G pencil-point needle in ambulatory surgery patients between the ages of 15-45 years and compare incidence of PDPH by age group, sex, and history of headache. METHODS: In this prospective cohort study, 300 patients (15-45 years old) who underwent simple knee arthroscopy under spinal anesthesia with a 27G pencil-point needle were enrolled. Verbal consent was obtained during the initial phone conversation between post-operative days (PODs) 2-5. A PDPH questionnaire was administered during this conversation and between PODs 7-10. Patients who reported a positional headache were contacted by a physician co-investigator, who determined PDPH diagnosis. RESULTS: Five patients were excluded from analysis due to complicated operative procedures or spinal needle size. The overall PDPH incidence was 2.0% (95% CI 0.9-4.4; 6/295). PDPH incidence in 15-19-year-old patients was 16.7% (95% CI 4.7-44.8; 2/12). The crude relative risk of PDPH was 15.4 (95% CI 2.8-114.4) for patients with and without history of headache and 2.5 (95% CI 0.5-14.8) for females vs. males. Overall, 16.3% (95% CI 12.5-20.9) of patients reported post-operative, non-positional headaches. CONCLUSIONS: There was a low overall incidence of PDPH among patients aged 15-45. Pre-planned subgroup analyses of PDPH incidence by age group revealed a high risk of PDPH among a small sample of 15-19-year-olds.
RESUMEN
BACKGROUND: Periacetabular osteotomy (PAO) reorients the acetabular cartilage through a complex series of pelvic osteotomies, which risks significant blood loss often necessitating blood transfusion. Therefore, it is important to identify effective strategies to manage blood loss and decrease morbidity after PAO. The purpose of this study was to determine the association of epsilon-aminocaproic acid (EACA), an antifibrinolytic agent, with blood loss from PAO. METHODS: Ninety-three patients out of 110 consecutive patients that underwent unilateral PAO for acetabular dysplasia met inclusion criteria. Fifty patients received EACA intraoperatively. Demographics, autologous blood predonation, anesthetic type, intraoperative estimated blood loss (EBL), cell-saver utilization, and transfusions were recorded. Total blood loss was calculated. Two-sample t-test and chi-square or Fisher's exact test were used as appropriate. The associations between EACA administration and calculated EBL, cell-saver utilization, intraoperative EBL, and maximum difference in postoperative hemoglobin were assessed via multiple regression, adjusting for confounders. Post hoc power analysis demonstrated sufficient power to detect a 250-mL difference in calculated EBL between groups. Alpha level was 0.05 for all tests. RESULTS: No demographic differences existed between groups. Mean blood loss and allogeneic transfusion rates were not statistically significant between groups (P = .093 and .170, respectively). There were no differences in cell-saver utilization, intraoperative EBL, and/or postoperative hemoglobin. There was a higher rate of autologous blood utilization in the group not receiving EACA because of a clinical practice change. CONCLUSIONS: EACA administration was not associated with a statistically significant reduction in blood loss or allogeneic transfusion in patients undergoing PAO.

Corrective surgery for scoliosis is an extensive procedure with well-known problems of postoperative pain control. Additional problems with nausea, vomiting, ileus, and sedation can result in delayed mobilization and a prolonged inpatient hospital stay. At our institution, a multimodal approach to pain management has been used to successfully address these issues. The use of intravenous acetaminophen has been a helpful adjunct to our armamentarium of pain medication in this patient population. We present an illustrative case of our use of multimodal analgesia beginning intraoperatively and continuing during the acute inpatient postoperative period.
