Paediatr Anaesth 2024; 34:438-447. [PMID: 38288667 DOI: 10.1111/pan.14843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 12/22/2023] [Accepted: 01/05/2024] [Indexed: 04/05/2024]
Abstract
BACKGROUND Posterior spinal fusion is the most common surgical procedure performed for correction of adolescent idiopathic scoliosis in the United States. Intraoperative methadone has been shown to improve pain control in adult patients undergoing complex spine surgery, and current pediatric studies show encouraging results; however, prospective randomized-controlled trials are lacking in the pediatric literature. AIMS We conducted a single-center double-blind randomized-controlled trial to compare intraoperative use of methadone to morphine in pediatric patients undergoing posterior spinal fusion. METHODS A total of 47 adolescents undergoing posterior spinal fusion were randomized (stratified by sex) to either a methadone (n = 25) or morphine (n = 22) group. The primary outcome was postoperative opioid consumption. Secondary outcomes included postoperative pain severity, opioid-related side effects, and ratio of patient-controlled analgesia injections: attempts as a behavioral index of uncontrolled pain. RESULTS Patients in the methadone group consumed less total opioid postoperatively (median [interquartile range], 0.3 mg/kg [0.1, 0.5]) than patients in the morphine group (0.3 mg/kg [0.2, 0.6]), median difference [95% confidence interval] -0.07 [-0.2 to 0.02]; (p = .026). Despite the lower amount of opioid used postoperatively, pain scores for the methadone group (3.5 [3.0, 4.3]) were not significantly different from those in the morphine group (4.0 [3.2, 5.0]; p = .250). Groups did not differ on opioid-related side effects. CONCLUSIONS A two-dose intraoperative methadone regimen resulted in decreased opioid consumption compared to morphine. Although the clinical significance of these results may be limited, the analgesic equipoise without increased opioid-related side effects and potential for a lower incidence of chronic pain may tip the balance in favor of routine methadone use for adolescents undergoing posterior spinal fusion.

Abstract
Cell‐free circulating DNA (cfDNA), extracted by liquid biopsy, has been studied as a noninvasive biomarker for various diseases. The potential of cfDNA fragment size and level as a marker in lumbar canal stenosis (LCS) patients has never been studied. We investigated whether cfDNA is a biomarker of low back pain, leg pain, leg numbness severity in patients with an LCS. Blood samples were obtained from patients with LCS (n = 22) before and immediately after spinal surgery. Plasma DNA was isolated and examined for cfDNA fragment size and concentration. A cohort of healthy volunteers (n = 5) constituted the control group. The cfDNA fragment size tended to be shorter in patients than in healthy controls, but this difference was not significant (P = .186). cfDNA level was significantly higher in LCS patients (mean 0.614 ± 0.198 ng/μL, range 0.302‐1.150 ng/μL) than in healthy controls (mean 0.429 ± 0.064 ng/μL, range 0.366‐0.506 ng/μL) (P = .008). cfDNA level correlated positively with average pain (r = .435, P = .026) and leg numbness (r = .451, P = .018). cfDNA fragment size did not differ from before to after surgery, but cfDNA level increased postoperatively in patients with LCS. This was the first study investigating whether cfDNA fragment size and level are associated with pain in patients with LCS. Our findings suggest that cfDNA level may be an objective indicator of pain and surgical invasiveness in patients with LCS.

Postoperative lumbar spine MRI: How well does a radiology report that raises suspicion for infection correlate with true clinical infection? J Clin Neurosci 2021; 92:6-10. [PMID: 34509263 DOI: 10.1016/j.jocn.2021.07.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 07/18/2021] [Accepted: 07/25/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Interpretation of a lumbar spine MRI in the immediate postoperative period is challenging, as postoperative tissue enhancement and fluid collections may be mistaken for infection. Radiology reports may use ambiguous language, creating a clinical problem for a surgeon in determining whether a patient needs treatment with antibiotics or revision surgery. Moreover, retrospective criticism of management in instances of a true infection may lead to medicolegal ramifications. METHODS A retrospective review of patients undergoing posterior-approach lumbar decompressive surgery with or without fusion over a 30-month period identified those undergoing postoperative MRI within 10 weeks of surgery. Patients initially operated upon for infection were excluded. The MRI reports were analyzed for language describing findings suspicious for infection and those of these with true infections were identified. RESULTS Of 487 patients undergoing posterior lumbar spine decompression surgery, 68 (14%) had postoperative MRI within 10 weeks. Of these, the radiology reports raised suspicion for infection in 20 (29%), of which 2 (10%) patients had a true infection. Two patients underwent reoperation for new motor deficit from seroma/hematoma. Of 63 patients who had MRI to evaluate complaints of back and/or leg pain without new motor deficits, the MRI significantly altered management in 3 patients (4.8%). CONCLUSION Radiology reports of postoperative lumbar spine MRIs frequently use language that raises suspicion for infection; but it is uncommon, however, that these patients harbor true infections. A radiology report describing possible infectious findings may not be considered significant without corroboration with other laboratory and clinical data.

C-reactive protein in spinal surgery: more predictive than prehistoric. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:1261-1269. [PMID: 33682035 DOI: 10.1007/s00586-021-06782-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 01/10/2021] [Accepted: 02/18/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE In spinal surgery, surgical site infections (SSI) after dorsal spondylodesis lead to severe short- and long-term complications. Despite various clinical and serological evidence, the detection of a postoperative SSI remains crucial. In this retrospective cohort study, we determined the prognostic value of C-reactive protein (CRP) kinetics after open reduction and dorsal spondylodesis in the development of a SSI. METHODS We retrospectively analyzed 192 patients from 2016 to 2018 undergoing open reduction and dorsal spondylodesis with and without SSI for 20 days at a level-I trauma center and assessed their serological and clinical characteristics. RESULTS On day 7 and 8 after surgery, patients who developed a SSI displayed significantly higher CRP levels. A second peak after the initial maximum of CRP and a restricted failure to decline as well as a maximum CRP of more than 225 mg/l predict an infectious complication with a sensitivity of 92.9%, and a specificity of 78.2%. A binary logistic regression leads to 85.7% and 69.7%, respectively. A one-phase decay exponential regression can predict 75.6% of the variance after the initial peak of CRP. CONCLUSION Our study demonstrates a high value of postoperative CRP kinetics in SSI detection after dorsal spondylodesis. Moreover, we observed typical CRP levels with a specific course as indicative predictors that may facilitate an early SSI detection in clinical practice.

Abstract
PURPOSE Interleukin 6 (IL-6) and the acute phase C-reactive protein (CRP) blood concentrations after lumbar spine fusion may be affected by age. The purpose of this prospective observational study was to assess postoperative serum levels of pro-inflammatory IL-6 and CRP after instrumented lumbar spine fusion surgery. We hypothesized that older patients would have increased levels of IL-6 and CRP after surgery. METHODS IL-6 and high-sensitive CRP biochemical marker levels were measured before instrumented spinal fusion, and postoperatively at 1 and 3 days, 6 weeks, and 3 months. The 49 patients in this sample were divided into two groups: age ≤ 60 years ( n = 23) and age > 60 years ( n = 26). RESULTS Acute changes in IL-6 high-sensitivity and CRP from preoperative levels to postoperative day (POD) 1 increased with age. Mean (95% CI) difference between the age-groups in changes of IL-6 at PODs 1 and 3 was 45 pg/ml (10-83, p = 0.014) and 20 pg/ml (5-36, p = 0.021), respectively. Mean (95% CI) difference between groups in changes of CRP at PODs 1 and 3 was 9.6 mg/l (-3.5 to 22.7, p = 0.47) and 24.8 mg/l (-17 to 67, p = 0.33), respectively. Both groups had decreased IL-6 and CRP levels at 6 weeks after surgery compared to the preoperative level. CONCLUSIONS Elevation of IL-6 and CRP is stronger in patients over 60 years old after instrumented lumbar spinal fusion. The CRP and IL-6 are sensitive markers for acute postoperative inflammation. Even high acute CRP values do not necessarily indicate postoperative infection.

Abstract
Introduction: The current gold standard technique for lumbar disc herniation (LDH) is open lumbar microdiscectomy. The use of a tubular retractor system in the microdiscectomy technique can minimize tissue trauma by muscle-splitting sequential dilation during the surgical approach. This review aimed to describe the devices and surgical procedure of this minimally invasive microdiscectomy (MI-MD) and to discuss the pros and cons of the use of tubular retractors.Areas covered: Published medical literatures were extensively reviewed to summarize the practical devices and techniques related to the MI-MD for LDH. The placement of the tubular retractor by gradual muscle-splitting dilation technique may reduce muscle damage and postoperative wound pain. The use of flexible arm may easily change the tube direction and create a wide surgical field.Expert opinion: With reference to published literature, the MI-MD provides comparable clinical outcomes with less tissue trauma and early recovery. Development of devices for MI-MD is still ongoing. Extensive studies, including high-quality randomized trials, are required to establish a more practical and relevant MI-MD technique.

Abstract
Purpose: This study is aimed to investigate an association between perioperative C-reactive protein (CRP) levels and both opioid consumption and postoperative pain scores in postoperative days (PODs) in patients who underwent laparoscopic major abdominal surgery. We hypothesized that postoperative opioid requirements and numeric rating scale (NRS) pain scores would be positively associated with perioperative CRP levels. Patients and method: Medical records from 4,653 patients who underwent a laparoscopic major abdominal surgery from January 2010 to December 2016 were retrospectively reviewed. Generalized linear regression analysis was used to identify the association of preoperative and postoperative CRP levels, and increase in CRP level (postoperative CRP level – preoperative CRP level) with postoperative pain outcomes during POD 0–3. Results: An increase of 1 mg dL−1 of postoperative CRP level was significantly associated with 1.4% increase morphine equivalent consumption [exponentiated regression (Exp) coefficient: 0.014, 95% CI (0.011, 0.016), P<0.001], whereas preoperative CRP levels were not significantly associated with morphine equivalent consumption on POD 0–3 (P=0.450). A 1 mg dL−1 of increase in CRP level was significantly associated with 1% increase of morphine equivalent consumption [Exp coefficient: 0.010, 95% CI (0.008, 0.012), P<0.001]. Postoperative CRP levels were positively associated with NRS pain scores on POD 1, POD 2, and POD 3 (P<0.001). Increases of CRP levels were also positively associated with NRS pain scores on POD 0, POD 1, POD2, and POD3 (P<0.05). Conclusion: These results suggest postoperative CRP levels and increases in CRP levels are positively associated with opioid consumption and higher pain scores after major laparoscopic abdominal surgery.

Abstract
STUDY DESIGN Prospective study. OBJECTIVE To characterize the normal pattern of kinetics of postoperative C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) after decompression, spinal instrumentation, and posterolateral fusion in 1, 2, and more than 2 levels. METHODS Blood specimens were obtained from patients who underwent posterior decompression, instrumentation with pedicular screws, and posterolateral fusion from June 2009 to January 2011. CRP and ESR levels were measured on the day before surgery and on postoperative days 1, 3, 7, 11, 14, 28, and 42. RESULTS Mean CRP levels peaked on the third day postoperatively in all groups. By day 7 postoperatively, it had dropped rapidly. At the 14th and 28th postoperative days, decreases to normal CRP levels were found in 16% and 80% of all patients, respectively. The pattern of decline in CRP was similar among groups. Values of ESR increased and peaked between the third and seventh postoperative days. ESR values gradually decreased. At the 42 day postoperatively, ESR level still remain above normal values in all groups. CONCLUSIONS We compared conventional operation groups of 1-, 2-, and more than 2-level posterior instrumentation and found no statistically significant differences in the peak of CRP level, the ESR value, and the pattern of decline. CRP levels of 80% of the patients returned to normal within 4 weeks.

Abstract
Over the last decades, minimally invasive surgery (MIS) techniques entered in the surgical routine due to their major advantage in reducing the unnecessary exposure of tissue and, thus, the trauma. Even in the context of orthopedics and spine surgery these practices have been widely developed and applied. Besides the clinical outcome of the patients, few studies have quantitatively assessed the traumatic and inflammatory effects of a specific surgical technique. Indeed, currently, a universally accepted biological outcome measure, such as a panel of biochemical markers, to define the success of MIS approach is still lacking. We reviewed the literature to collect the published data regarding the quantitative analysis of trauma induced by either conventional or minimally invasive surgery with the aim of highlighting evidence useful to guide future studies. Previous publications show some evidence in support of the hypothesis that MIS approaches are less traumatic, and possibly less pro-inflammatory, than conventional ones. Creatin kinase (as a marker of muscular damage) and C-reactive protein (as a marker of systemic inflammation) seem to reproducibly follow different trends in minimally invasive surgery compared to conventional procedures. Moreover, cytokines, such as interleukin (IL)-6 and IL-10 are also promising markers in this context.

Abstract
A hallmark of the rheumatic diseases, including systemic lupus erythematosis, spondyloarthritis, and rheumatoid arthritis, has been sustained inflammation, which typically targets the joint and may lead to joint destruction. Inflammation also plays a role in atherosclerotic cardiovascular disease, which is highly prevalent in patients with rheumatic diseases. Total joint arthroplasty, considered an intermediate cardiac risk procedure by the American College of Cardiology, maintains an important role in the management of rheumatic disease patients who progress to end-stage joints. The purpose of this article is to discuss the role of inflammation in cardiovascular disease, the prevalence of cardiovascular disease in patients with systemic rheumatic diseases, and the role of cardiovascular risk assessment when these patients undergo total joint arthroplasty.

Abstract
Background and Aims: Surgical site infections are relatively common after spinal deformity surgery. Early detection of deep wound infections is important, since it may allow retention of spinal instrumentation. However, serum C-reactive protein and erythrocyte sedimentation rate may remain elevated for almost 6 weeks, making differential diagnosis of systemic inflammatory response and acute deep bacterial wound infection difficult. Plasma procalcitonin has been suggested to be a useful indicator for bacterial infection. However, there are no studies evaluating behavior of procalcitonin in patients undergoing major spine surgery with instrumentation. Materials and Methods: A total of 50 consecutive adolescents (37 idiopathic scoliosis and 13 neuromuscular scoliosis, mean age = 15 years at surgery and follow-up time = 21 months (range = 12–29 months)) undergoing scoliosis surgery participated in this prospective follow-up study. White blood cell count, serum C-reactive protein, and plasma procalcitonin levels were measured on the day before surgery, on the day of surgery, and daily thereafter for 1 week. None of the patients developed signs of acute or delayed wound infection during the follow-up period; however, two neuromuscular scoliosis patients developed severe postoperative pneumonia, and their inflammatory parameter data will be reported separately. Results: Plasma procalcitonin levels peaked on the first postoperative day (mean = 0.19 ng/mL, range = 0.04–1.29 ng/mL), and mean values were less than 0.5 ng/mL during the whole first postoperative week, while C-reactive protein remained elevated during the whole first postoperative week (highest mean value = 63.8 mg/L (range = 5–248 mg/L) on third postoperative day). Patients with idiopathic scoliosis had lower C-reactive protein levels (p < 0.05 from first to sixth postoperative day) and lower procalcitonin levels (p < 0.05 from third to seventh postoperative day) than neuromuscular scoliosis patients. Two patients with postoperative pneumonia showed elevated procalcitonin values over the whole postoperative week (22.34 ng/mL and 0.72 ng/mL highest values, respectively). Conclusions: Elevated plasma procalcitonin levels seem useful when excluding acute deep wound infection from systemic inflammatory response.

Abstract
BACKGROUND One of the major concerns in transsphenoidal surgery are infections because the approach to the pituitary includes a route of microbial colonization. To minimize the associated morbidity and mortality, a surveillance program is crucial to monitor for perioperative infections. METHODS For 1 year, we analysed body temperature (BT), erythrocyte sedimentation rate (ESR), white blood cell count (WBC), C-reactive protein (CRP), interleukin 6 (IL-6) and lipopolysaccharide-binding-protein (LBP) following elective transsphenoidal pituitary surgery. Samples were collected on admission, day 1, 3 and 7 as well as 3 months postoperatively. RESULTS In 116 patients, all data were available. No postoperative infections occurred within the first postoperative week. BT (37.6 ± 0.6, baseline 37.0 ± 0.5 °C), WBC (11,366 ± 2,541, baseline 6,861 ± 2,123/μl), CRP (25.3 ± 22.6, baseline 3.1 ± 6 mg/l), IL-6 (12 ± 13, baseline 2.7 ± 2.6 pg/ml), and LBP (11.3 ± 4.9, baseline 5.7 ± 2.7 μg/ml) peaked on day 1 postoperatively (each p = 0.001), while ESR peaked on day 3 (25 ± 16, baseline 13 ± 11 mm/h, p = 0.001). BT and IL-6 normalized by day 3 and CRP by day 7, while ESR (23 ± 16 mm/h, p = 0.001), WBC (7,807 ± 2,750/μl, p = 0.001) and LBP (7.3 ± 2.6 μg/ml, p = 0.028) were still increased by day 7. CONCLUSION The present study establishes normative values for an infection surveillance following transsphenoidal pituitary surgery. CRP, a convenient and reasonable priced parameter, is affected by the procedure for the first postoperative week. IL-6 is more robust and allows a close monitoring on the expense of additional pricing. ESR, WBC and LBP are sustained affected by surgery, and do not offer any advantage. Since no infections were observed, we were unable to calculate the respective sensitivity and specificity.

Abstract
The management of perioperative cardiovascular risk in patients with rheumatoid arthritis (RA) is challenging due to the independent contribution to risk by high grade inflammatory mechanisms and the underestimation of risk by traditional cardiac risk factors alone. RA is associated with accelerated rates of subclinical atherosclerosis and markedly higher rates of both myocardial infarction and sudden cardiac death over non-RA controls. There is an absence of prospectively validated perioperative coronary heart disease (CHD) risk assessment tools for this unique patient population and available guidelines may fail to identify those patients most at risk. We examine a singular case of first time myocardial infarction after uncomplicated elective surgery in an adult RA patient with an unrevealing preoperative cardiac assessment. We also review the current literature for shared pathogenic mechanisms between systemic inflammation and atherosclerosis, discuss clinical and biologic markers such as C-reactive protein (CRP) in RA patients associated with heightened cardiac risk and discuss recommendations based on available evidence for cardiovascular risk management in this at risk cohort.
