RESUMEN
BACKGROUND: Adolescent Idiopathic Scoliosis (AIS) affects 2%-4% of the general pediatric population. While surgical correction remains one of the most common orthopedic procedures performed in pediatrics, limited consensus exists on the perioperative anesthetic management. AIMS: To examine the current state of anesthetic management of typical AIS spine fusions at institutions which have a dedicated pediatric orthopedic spine surgeon. METHODS: A web-based survey was sent to all members of the North American Pediatric Spine Anesthesiologists (NAPSA) Collaborative. This group included 34 anesthesiologists at 19 different institutions, each of whom has a Harms Study Group surgeon performing spine fusions at their hospital. RESULTS: Thirty-one of 34 (91.2%) anesthesiologists completed the survey, with a missing response rate from 0% to 16.1% depending on the question. Most anesthesia practices (77.4%; 95% confidence interval [CI], 67.7-93.4) do not have patients come for a preoperative visit prior to the day of surgery. Intravenous induction was the preferred method (74.2%; 95% CI 61.3-89.9), with the majority utilizing two peripheral IVs (93.5%; 95% CI 90.3-100) and an arterial line (100%; 95% CI 88.8-100). Paralytic administration for intubation and/or exposure was divided (51.6% rocuronium/vecuronium, 45.2% no paralytic, and 3.2% succinylcholine) amongst respondents. While tranexamic acid was consistently utilized for reducing blood loss, dosing regimens varied. When faced with neuromonitoring signal issues, 67.7% employ a formal protocol. Most anesthesiologists (93.5%; 95% CI 78.6-99.2) extubate immediately postoperatively with patients admitted to an inpatient floor bed (77.4%; 95% CI 67.7-93.3). CONCLUSION: Most anesthesiologists (87.1%; 95% CI 80.6-99.9) report the use of some form of an anesthesia-based protocol for AIS fusions, but our survey results show there is considerable variation in all aspects of perioperative care. Areas of agreement on management comprise the typical vascular access required, utilization of tranexamic acid, immediate extubation, and disposition to a floor bed. By recognizing the diversity of anesthetic care, we can develop areas of research and improve the perioperative management of AIS.

INTRODUCTION: Although 200 000 adolescents undergo anterior cruciate ligament reconstruction (ACLR) surgery annually, no benchmarks for pediatric post-ACLR pain management exist. We created a multicenter, prospective, observational registry to describe pain practices, pain, and functional recovery after pediatric ACLR. METHODS: Participants (n=519; 12-17.5 years) were enrolled from 15 sites over 2 years. Data on perioperative management and surgical factors were collected. Pain/opioid use and Lysholm scores were assessed preoperatively, on postoperative day 1 (POD1), POD3, week 6, and month 6. Descriptive statistics and trends for opioid use, pain, and function are presented. RESULTS: Regional analgesia was performed in 447/519 (86%) subjects; of these, adductor canal single shot was most frequent (54%), nerve catheters placed in 24%, and perineural adjuvants used in 43%. On POD1, POD3, week 6, and month 6, survey response rates were 73%, 71%, 61%, and 45%, respectively. Over these respective time points, pain score >3/10 was reported by 64% (95% CI: 59% to 69%), 46% (95% CI: 41% to 52%), 5% (95% CI: 3% to 8%), and 3% (95% CI: 1% to 6%); the number of daily oxycodone doses used was 2.8 (SD 0.19), 1.8 (SD 0.13), 0, and 0. There was considerable variability in timing and tests for postdischarge functional assessments. Numbness and weakness were reported by 11% and 4% at week 6 (n=315) and 16% and 2% at month 6 (n=233), respectively. CONCLUSION: We found substantial variability in the use of blocks to manage post-ACLR pain in children, with a small percentage experiencing long-term pain and neurological symptoms. Studies are needed to determine best practices for regional anesthesia and functional assessments in this patient population.
RESUMEN
PURPOSE: This study analyzes the implementation of the routine use of quadratus lumborum blocks (QLBs) on postoperative pain and opioid consumption among children undergoing laparoscopic appendectomy compared to those not receiving regional anesthesia. METHODS: Children undergoing laparoscopic appendectomy within a multi-hospital children's healthcare system were retrospectively reviewed from 2017 to 2021. Patients were stratified by appendicitis type (uncomplicated vs. complicated). Pain scores and opioid consumption in the post-anesthesia care unit (PACU) and within the first 24 h postoperatively were compared by block status (no block [NB] vs. QLB) and appendicitis type. RESULTS: 2033 patients were reviewed, and 610 received a QLB. The frequency of rescue opioid use was reduced in the PACU (uncomplicated: QLB 46.6% vs. NB 54.6%, p = 0.005; complicated: QLB 28.5% vs. NB 39.9%, p = 0.01) and postoperatively (complicated: QLB 33.7% vs. NB 52.9%, p < 0.001) for those who received a QLB. This resulted in reduced opioid consumption as measured by morphine milligram equivalents per kilogram postoperatively. CONCLUSION: QLBs can be safely administered in children and provide improvements in opioid consumption postoperatively. QLBs should remain a strongly favored regional anesthetic technique because of their wide applicability for abdominal surgeries to minimize rescue opioid analgesic use. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Available literature comparing spinal anesthesia (SA) to general anesthesia (GA) in the pediatric population describes multiple benefits in appropriately selected patients including cost reduction, lower incidence of complications, and shorter operative times. In patients undergoing urologic procedures, data are sparse. OBJECTIVE: Our goal was to expand on the paucity of existing urologic literature as SA appears to be uniquely suited for a substantial number of its common pediatric procedures. METHODS: Within a single institution, patients who had a urologic procedure performed under SA between May 2019 and July 2021 and were less than 18 months old were compared with a matched cohort of patients who had GA. The SA and GA groups were compared by two-sample t-tests, chi-square test for independence, and Fisher's exact test. RESULTS: There were a total of 184 SA and 202 GA patients. There was no significant difference in the demographics except that SA patients were younger and weighed less than GA patients. The patients in the SA group needed less opioids both during the surgery (0% vs 26.1% p N/A) and in the immediate postoperative period when compared with GA patients (0% vs 18.2% p N/A). The patients who had SA had fewer complications necessitating PICU admission, or cancellation of surgery (0% vs 6.8% p = 0.03). Total anesthesia and emergence time were lower for SA patients (41 vs 50.2 p = 0.001 & 3.4 vs 6.1 p = 0.001). Both surgery and total OR time were not different between the groups (37.6 vs 35.5 p = 0.35 and 56.3 vs 54.4 p = 0.49). Overall, raw material cost was also found to be lower per procedure in the SA group vs the GA group ($8.90 vs $38.8: 77% reduction). Adjusted total mean costs for the surgery were not different between groups. The reduction in opioid use postoperatively also suggests reduced cost in the management of postoperative pain in the SA group. DISCUSSION: Total anesthesia time, opioid use, and serious complications were all significantly lower in the SA group. We did not find significant difference in total surgery cost between two groups. However, patients who had SA had better pain control and needed less rescue analgesics in the immediate postoperative period. No patients in either group were sent home with opioids. CONCLUSION: Spinal anesthesia was found to be an equally effective and appropriate alternative to GA with many proposed benefits for common pediatric urologic procedures. With further research, SA may prove to be a safer alternative in patients at risk for complications related to GA general anesthesia while also offering a cost benefit.

BACKGROUND: Many studies evaluating opioid stewardship interventions' effects on postoperative pain rely on emergency department (ED) visits or readmissions, but patient-reported pain scores represent a more complete picture of the postoperative experience. This study compares patient-reported pain scores after ambulatory pediatric and urologic procedures and the effect of an opioid stewardship intervention that nearly eliminated the use of outpatient narcotics. METHODS: This is a retrospective comparative study including 3173 pediatric patients who underwent ambulatory procedures from 2015 to 2019, during which there was an intervention to reduce narcotic prescriptions. Postoperative day one phone calls assessed pain levels using a four-point scale (no pain, mild pain, moderate pain controlled with medication, or severe pain uncontrolled with medication). We quantified the proportion of patients prescribed opioids pre-versus post-intervention and compared pain scores for patients receiving opioid versus non-opioid regimens. RESULTS: Opioid prescription rates demonstrated a 6.5-fold reduction after opioid stewardship efforts. The majority of patients (2838) received non-opioids, with only 335 patients receiving opioids. Opioid patients reported moderate/severe pain slightly more than non-opioid patients (14.1% vs. 10.4%, p = 0.04). On by-procedure analyses, there were no subgroups in which non-opioid patients reported significantly higher pain scores. CONCLUSIONS: Non-opioid postoperative pain regimens appear to be effective, with only 10.4% of patients reporting moderate/severe pain after ambulatory procedures. Future studies assessing patient-reported outcomes are necessary to optimize pain control for all patients and to determine whether there is ever an indication for opioid prescription after ambulatory general pediatric or urologic surgery. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Background: Systemic inflammatory response syndrome (SIRS) is known to complicate postsurgical intensive care patients. We noticed that roughly half children with cerebral palsy who undergo posterior spinal fusion (PSF) for neuromuscular scoliosis developed SIRS in the intensive care unit. There is a paucity of literature detailing the impact of intraoperative causes of postoperative SIRS and downstream consequences in these patients. Study purpose was to understand the factors associated with SIRS in children who undergo PSF for neuromuscular scoliosis. Methods: This retrospective, case control study included children who underwent PSF for neuromuscular scoliosis. Patients with idiopathic scoliosis, osteogenesis imperfecta, and tracheotomy were excluded. Subjects were divided into two study groups based on the diagnosis of SIRS in the intensive care unit. Descriptive statistical analysis was used to identify factors associated with SIRS; a regression analysis was used to further evaluate the independent and significant influence of these factors. Results: There was no significant difference in the demographic and other preoperative variables. However, total blood products (ml/kg) administered was significantly higher among the SIRS group compared with the non-SIRS group (54.4±41.0 vs 34.1±21.5 P <0.034). Percent of patients remaining intubated was greater in the SIRS group compared with the non-SIRS group (44.1% vs 7.0%, P < 0.001). The regression model revealed that the odds to develop SIRS in patients who were not extubated were 7.467-fold higher (CI: 1.534-36.347) compared with those who were extubated (p=0.013). Conclusions: The incidence of SIRS is significantly higher among the patients who were not extubated at the end of PSF surgery. Further prospective studies are needed to look at the factors that impede the ability to extubate these patients at the end of surgery.
RESUMEN
PURPOSE: In major trauma with massive blood loss, higher fresh frozen plasma (FFP)-to-red blood cell (RBC) ratios have been associated with improved morbidity and mortality. Our population of patients with neuromuscular scoliosis undergoing posterior spinal fusion (PSF) often lose volumes of blood considered massive, that is, half a blood volume in 3 hours. In this retrospective cohort study, we examined the association of FFP ratio with blood loss in this elective surgical population. METHODS: Patients with neuromuscular scoliosis undergoing PSF with unit rod fixation were identified from our anesthesia cases database. The patients were divided into two groups: the low FFP group received FFP-to-RBC≤0.5, and the high FFP group received FFP-to-RBC>0.5. After controlling for a false discovery rate in the univariate analysis, a logistic and linear regression was performed to understand the contribution of the significant factors associated with increased blood loss. RESULTS: Risk estimation showed that patients in the low FFP group were more likely to lose >120% blood volume (odds ratio, 3.87; 95% confidence interval, 2.03-7.38). Linear regression revealed that each unit of increase in FFP-to-RBC ratio was associated with a 27.5% (95% confidence interval, -43.12-11.89) mean reduction in blood volume loss. CONCLUSIONS: In our retrospective study, we found that FFP-to-RBC ratio was significant independent predictor of blood loss in this group of complex spine patients undergoing PSF. Thus, in patients with neuromuscular scoliosis undergoing posterior spine fusion, use of higher ratio of FFP to RBC may decrease blood loss.

BACKGROUND: Spinal deformity is one of the secondary musculoskeletal problems that occur with cerebral palsy (CP). Of the co morbidities associated with CP and spinal deformity, cardiac function is of theoretical concern. OBJECTIVE: The goal of our study was to determine the clinical relevance of routine preoperative cardiology evaluation via echocardiogram for patients with CP presenting for posterior spine fusion (PSF) surgery. METHODS: A retrospective chart review was performed of CP patients presenting for scoliosis surgery. The data collected for each patient included: age, sex, height, weight, Cobb angle, and medical history. All patients had a preoperative cardiac evaluation. RESULTS: Seventy-two patients were included. The mean age was 13.6 ± 3.4 years. Left ventricular systolic function was normal in all patients; the mean shortening fraction was 39.3 ± 6.2%. No patient had more than mild insufficiency of either the semilunar or atrioventricular valve. One patient was diagnosed with aortic root dilation as well as aortic valve insufficiency. All patients had PSF surgery without changes in anesthetic or surgical plans, and no patient experienced complications attributable to a cardiac origin. CONCLUSION: The results suggest that routine preoperative cardiology evaluation via echocardiogram for children with CP in the absence of clinical history or physical examination findings suggestive of cardiac disease is not necessary.

Crohn's disease is an inflammatory disease of the gastrointestinal tract, usually involving the ileum, that can lead to debilitating symptoms of abdominal pain, diarrhea and malabsorption during acute exacerbations. Because there is no known cause of the illness, treatment is based upon symptomatology and may ultimately require bowel resection if response to medical therapy is inadequate. Treatment with hyperbaric oxygen has shown promise in the reduction of inflammation associated with acute exacerbations of Crohn's disease, with alleviation of symptoms and an improvement in quality of life. We present two cases of pediatric patients with exacerbations of Crohn's disease who underwent cycles of hyperbaric oxygen therapy. Each patient was symptomatic and had no improvement despite prolonged medical therapy. Following treatment with hyperbaric oxygen, both patients showed resolution of the inflammatory lesions and improvement in conditions, allowing them to reduce drug therapy. Although the mechanisms by which hyperbaric oxygen reduce inflammation in Crohn's disease is poorly defined, this therapy seems to have offer a safe adjunct in the treatment of refractory exacerbations.

Serious complications following cervical epidural steroid injection are rare. Subdural injection of local anesthetic and steroid represents a rare but potentially life threatening complication. A patient presented with left sided cervical pain radiating into the left upper extremity with motor deficit. MRI showed absent lordosis with a broad left paramedian disc-osteophyte complex impinging the spinal cord at C5-6. During C5-6 transforaminal epidural steroid injection contrast in AP fluoroscopic view demonstrated a subdural contrast pattern. The needle was withdrawn slightly and repositioned. Normal lateral epidural and nerve root contrast pattern was subsequently obtained and injection followed with immediate improvement in radicular symptoms. There were no postoperative complications on subsequent clinic follow-up. The subdural space is a potential space between the arachnoid and dura mater. As the subdural space is larger in the cervical region, there may be an elevated potential for inadvertent subdural injection. Needle placement in the cervical subdural space during transforaminal injection is uncommon. Failure to identify aberrant needle entry within the cervical subdural space may result in life threatening complications. We recommend initial injection of a limited volume of contrast agent to detect inadvertent subdural space placement.
RESUMEN
Administration of carbon monoxide derived from carbon monoxide-releasing molecules has been demonstrated to enhance coagulation in vitro at small concentrations (100-200âµmol/l) in human and rabbit plasma. We sought to determine if carbon monoxide-releasing molecule-2 [tricarbonyldichlororuthenium (II) dimer, CORM-2] would improve coagulation in rabbit plasma in vitro via thrombelastography and in an in vivo preclinical rabbit model of ear bleeding time following administration of clopidogrel (20âmg/kg) with aspirin (10âmg/kg) via gavage. Addition of 100âµmol/l CORM-2 to rabbit plasma significantly improved coagulation. This procoagulant effect was blocked by pre-exposure of plasma to an agent that converts hemefibrinogen to methemefibrinogen in human plasma, preventing carbon monoxide binding and enhancement of coagulation. Rabbit ear bleeding time was 5.8â±â1.1âmin 2-3âh after clopidogrel/aspirin administration. Bleeding time significantly decreased to 2.6â±â0.6âmin, 5âmin after administration of CORM-2 (10âmg/kg; 279âµmol/l 'best-case' instantaneous concentration) intravenously. CORM-2 enhances plasmatic coagulation in a manner similar to that of human plasma in vitro, and plasmatic coagulation is enhanced in vivo by CORM-2 as well. Additional preclinical investigation of the effects of CORM-2 on coagulopathy (e.g. heparin or hemodilution mediated) utilizing this rabbit model is planned.
