Enhanced Recovery After Surgery 2.0: Optimizing Pain Management in Nuss Procedure: Cryoablation and Nerve Block Strategies for Reduced Opioid Use.

INTRODUCTION: Our study assesses the association between cryoablation, with and without nerve block supplementation, post-Nuss procedure pain, and opioid use in pectus excavatum (PE) patients. METHODS: We conducted a retrospective cohort study at a single center for PE patients who underwent the Nuss procedure from 2017 to 2022. Outcomes included postoperative opioid use (measured in oral morphine milligram equivalent per kilogram [OME/kg]), average pain score (scale 0-10), and length of stay (LOS). RESULTS: One hundred sixty-four patients (146 males and 18 females) were included, with 79 (48.2%) receiving neither cryoablation nor nerve block, 60 (36.6%) receiving intraoperative cryoablation alone, and 25 (15.2%) receiving both cryoablation and nerve block. The median age was 16 y. Nerve block recipients consumed fewer opioids during hospitalization than cryoablation alone and nonintervention groups (1.5 versus 2.3 versus 5.8 OME/kg, respectively, P < 0.0001). Average pain scores over the total LOS were lower in nerve block recipients (3.5 versus 3.8 versus 4.2, P = 0.03), particularly on postoperative day 0 (P = 0.002). Nerve block recipients had a shorter LOS than cryoablation alone and nonintervention groups (43.4 versus 54.7 versus 66.2 h, P < 0.0001). On multivariate analysis, cryoablation alone resulted in significantly less opioid use compared to no intervention (3.32 OME/kg reduction, 95% confidence interval -4.16 to -2.47, P < 0.0001). Addition of nerve block further reduced opioid use by 1.10 OME/kg (95% confidence interval -2.07 to -0.14, P = 0.04). CONCLUSIONS: Cryoablation with nerve block supplementation is associated with reduced pain, opioid use, and LOS post-Nuss for PE repair compared to cases without cryoablation or with cryoablation only. Cryoablation with regional nerve blocks should be considered for Nuss repair under the enhanced recovery after surgery pathway.

Thoracic and vertebral deformities in lung transplantation: perioperative complications and long-term prognoses.

BACKGROUND: Lung transplantation (LTx) is a crucial therapeutic strategy for patients suffering from end-stage respiratory diseases, necessitating precise donor-recipient size matching to ensure optimal graft function. While standard allocation protocols rely on predicted lung capacity based on factors such as sex, age, and height, a subset of patients with respiratory diseases presents an additional challenge - thoracic or vertebral deformities. These deformities can complicate accurate volume predictions and may impact the success of lung transplantation. METHODS: In this retrospective cohort study of patients who underwent LTx at Tohoku University Hospital between January 2007 and April 2022, with follow-up until October 2022, the primary objective was to assess the influence of thoracic and vertebral deformities on perioperative complications, emphasizing interventions, such as volume reduction surgery. The secondary objective aimed to identify any noticeable impact on long-term prognoses in recipients with these deformities. RESULTS: Of 129 LTx recipients analyzed, 17.8% exhibited thoracic deformities, characterized by pectus excavatum, while 16.3% had vertebral deformities. Perioperative complications, requiring delayed chest closure, tracheostomy, and volume reduction surgery, were more prevalent in the deformity group. Thoracic deformities were notably associated with the need for volume reduction surgery. However, long-term prognoses did not differ significantly between patients with deformities and those without. Vertebral deformities did not appear to significantly impact perioperative or long-term outcomes. CONCLUSIONS: This study highlights the prevalence of thoracic deformities in LTx recipients, correlating with increased perioperative complications, particularly the potential need for volume reduction surgery. Importantly, these deformities do not exert a significant impact on long-term prognoses. Additionally, patients with vertebral deformities, such as scoliosis and kyphosis, appear to be manageable in the context of LTx.

Vacuum bell therapy for pectus excavatum: a retrospective study.

BACKGROUND: Pectus excavatum, the most common chest wall deformity, is frequently treated with Nuss procedure. Here we will describe non-invasive procedure and analyze the variables associated vacuum bell therapy for patients with pectus excavatum. METHODS: Retrospective case-control study in a single center between July 2018 and February 2022, including patients with pectus excavatum treated with vacuum bell. Follow-up was continued to September 2022. The Haller index and Correction index was calculated before and after treatment to analysis the effectiveness of vacuum bell therapy. RESULTS: There were 98 patients enrolled in the treatment group, with 72 available for analysis, and the follow-up period ranged from 1.1 to 4.4 years (mean 3.3 years). When analyzing with the Haller Index, 18 patients (25.0%) showed excellent correction, 13 patients (18.1%) achieved good correction, and 4 patients (5.6%) had fair correction. The remaining patients had a poor outcome. Characteristics predicting a non-poor prognosis included initial age ≤ 11 years (OR = 3.94, p = 0.013) and patients with use over 24 consecutive months (OR = 3.95, p = 0.013). A total of 9 patients (12.5%) achieved a CI reduction below 10. Patients who started vacuum bell therapy at age > 11 had significantly less change compared to those who started at age ≤ 11 (P < 0.05). Complications included chest pain (5.6%), swollen skin (6.9%), chest tightness (1.4%) and erythema (15.3%). CONCLUSIONS: A certain percentage of patients with pectus excavatum can achieve excellent correction when treated with pectus excavatum therapy. Variables predicting better outcome including initial age ≤ 11 years both in HI and CI and vacuum bell use over 24 consecutive months in HI. In summary, pectus excavatum is an emerging non-invasive therapy for pectus excavatum and will be widely performed in a certain group of patients.

Reliability and validity of the Chinese revised version of the pectus excavatum evaluation questionnaire in children with pectus excavatum.

OBJECTIVE: This study aims to translate the Pectus Excavatum Evaluation Questionnaire(PEEQ) into Chinese, and to comprehensively assess subjective outcomes in quality of life of children with pectus excavatum. METHODS: The PEEQ was translated from English to Chinese as according to the PRO translation guidelines. Structural validity and reliability of the questionnaire were examined by validated factor analysis and Cronbach's alpha coefficient analysis respectively. RESULTS: The results of the validation factor analysis for the Chinese PEEQ parent's and child's questionnaires demonstrated that the fit indicators for each dimension met the required criteria. The overall Cronbach's alpha coefficient of parent's and child's questionnaires were 0.840 and 0.854. Both the item-level content validity index (I-CVI) and scale-level content validity index (S-CVI) of each sub-questionnaire were 1. CONCLUSION: The Chinese version of the PEEQ parent's questionnaire is suitable as a proxy assessment for patients with PE, but the child's questionnaire needs further adjustments.

The implementation of a pectus bar insertion enhanced recovery after surgery pathway: A quality improvement initiative.

BACKGROUND: Pectus excavatum repair is associated with significant discomfort, and pain is a primary contributor to postoperative hospital length of stay. Recent advances in postoperative pain control include the use of intercostal cryoablation techniques that may now make it possible to discharge patients on the day of surgery. Unnecessary variation in patient care and noncompliance with care bundles may be a factor in extended length of stay. The global aim of this quality improvement initiative was to successfully implement an enhanced recovery after surgery (ERAS) pathway on patients undergoing pectus excavatum repair. The SMART aim was to have a greater than 70% compliance for the perioperative bundle elements within 1 year of the pathway implementation. METHODS: Multiple Plan-Do-Study-Act (PDSA) cycles were designed to create and implement an ERAS pathway for patients undergoing a pectus bar insertion procedure. This multidisciplinary pathway was designed, managed, and implemented with key stakeholders from the Departments of Evidence Based Practice, Surgery, Anesthesiology, and Perioperative Nursing. Patient characteristics, outcomes, and compliance with elements of the pathway were measured for analysis for both the baseline and post-intervention groups with monthly automated reports. RESULTS: After implementation of the ERAS pathway, data on the first 50 patients showed a 90% compliance with the perioperative bundle elements. Mean length of stay was significantly decreased from 33 h (95% CI [28.76, 37.31]) to 18 h (95% CI [14.54, 21.70]). There were zero readmissions within 24 hours for patients who were discharged on the day of surgery. CONCLUSION: Employing a multidisciplinary approach in both planning and execution that standardized clinician practices and minimized unnecessary variation in patient care, an ERAS pathway for pectus bar insertion has been successfully established at our institution.

Pectus excavatum: the effect of tricuspid valve compression on cardiac function.

BACKGROUND: Pectus excavatum (PE) is a common congenital chest wall deformity with various associated health concerns, including psychosocial impacts, academic challenges, and potential cardiopulmonary effects. OBJECTIVE: This study aimed to investigate the cardiac consequences of right atrioventricular groove compression in PE using cardiac magnetic resonance imaging. MATERIALS AND METHODS: A retrospective analysis was conducted on 661 patients with PE referred for evaluation. Patients were categorized into three groups based on the degree of right atrioventricular groove compression (no compression (NC), partial compression (PC), and complete compression(CC)). Chest wall indices were measured: pectus index (PI), depression index (DI), correction index (CI), and sternal torsion. RESULTS: The study revealed significant differences in chest wall indices between the groups: PE, NC=4.15 ± 0.94, PC=4.93 ± 1.24, and CC=7.2 ± 4.01 (P<0.0001). Left ventricle ejection fraction (LVEF) showed no significant differences: LVEF, NC=58.72% ± 3.94, PC=58.49% ± 4.02, and CC=57.95% ± 3.92 (P=0.0984). Right ventricular ejection fraction (RVEF) demonstrated significant differences: RVEF, NC=55.2% ± 5.3, PC=53.8% ± 4.4, and CC=53.1% ± 4.8 (P≥0.0001). Notably, the tricuspid valve (TV) measurement on the four-chamber view decreased in patients with greater compression: NC=29.52 ± 4.6; PC=28.26 ± 4.8; and CC=24.74 ± 5.73 (P<0.0001). CONCLUSION: This study provides valuable insights into the cardiac consequences of right atrioventricular groove compression in PE and lends further evidence of mild cardiac changes due to PE.

The electrocardiographic manifestations of pectus excavatum before and after surgical correction.

BACKGROUND: Pectus excavatum (PEx) can cause cardiopulmonary limitations due to cardiac compression and displacement. There is limited data on electrocardiogram (ECG) alterations before and after PEx surgical repair, and ECG findings suggesting cardiopulmonary limitations have not been reported. The aim of this study is to explore ECG manifestations of PEx before and after surgery including associations with exercise capacity. METHODS: A retrospective review of PEx patients who underwent primary repair was performed. ECGs before and after surgical correction were evaluated and the associations between preoperative ECG abnormalities and cardiopulmonary function were investigated. RESULTS: In total, 310 patients were included (mean age 35.1 ± 11.6 years). Preoperative ECG findings included a predominant negative P wave morphology in V1, and this abnormal pattern significantly decreased from 86.9% to 57.4% (p < 0.001) postoperatively. The presence of abnormal P wave amplitude in lead II (>2.5 mm) significantly decreased from 7.1% to 1.6% postoperatively (p < 0.001). Right bundle branch block (RBBB) (9.4% versus 3.9%, p < 0.001), rsr' patterns (40.6% versus 12.9%, p < 0.001), and T wave inversion in leads V1-V3 (62.3% vs 37.7%, p < 0.001) were observed less frequently after surgery. Preoperative presence of RBBB (OR = 4.8; 95%CI 1.1-21.6) and T wave inversion in leads V1-3 (OR = 2.3; 95%CI 1.3-4.2) were associated with abnormal results in cardiopulmonary exercise testings. CONCLUSION: Electrocardiographic abnormalities in PEx are frequent and can revert to normal following surgery. Preoperative RBBB and T wave inversion in leads V1-3 suggested a reduction in exercise capacity, serving as a marker for the need for further cardiovascular evaluation of these patients.

Spinal posture, mobility, and position sense in adolescents with chest wall deformities: a comparison of pectus excavatum, pectus carinatum and healthy peers.

PURPOSE: The study aimed to compare spinal posture, mobility, and position sense in adolescents with pectus excavatum (PE), pectus carinatum (PC), and healthy control (HC). METHODS: 22 with PE, 22 with PC, and 21 HC were included in the study. The spinal posture (thoracic kyphosis, lumbar lordosis, pelvic tilt, thoracic, lumbar, pelvic lateral tilt angles) and mobility (thoracic, lumbar, hip/sacral, and overall, in the sagittal and frontal plane) with the spinal mouse, and spinal position sense (repositing errors) with the inclinometer were assessed. RESULTS: The thoracic kyphosis angle of PE and PC was higher than in HC (p < 0.001; p = 0.001). Hip/sacral mobility in the sagittal plane was lower in the PE and PC than control, respectively (p < 0.001; p < 0.001). Overall sagittal spinal mobility (p:0.007) and hip/sacral mobility in the frontal plane (p:0.002) were lower in the PC than in HC. Overall frontal spinal mobility was lower in the PE and PC than in HC (p:0.002; p:0.014). The PE and PC repositing errors were higher (p < 0.001; p:0.014). CONCLUSION: The study found that adolescents with PE and PC had decreased spinal mobility, spinal alignment disorders, and a decline in spinal position sense. It is important not to overlook the spine during physical examinations of adolescents with chest wall deformities. In clinical practice, we suggest that adolescents with chest deformities should undergo a spine evaluation and be referred for physical therapy to manage spinal disorders.

Sternal cleft and pectus excavatum: an overlooked congenital association?

BACKGROUND: Sternal cleft (SC), a rare thoracic malformation, is associated with pectus excavatum (PE) in 2.6-5% of cases. It remains unclear if these conditions are congenitally linked or if SC repair triggers PE. To investigate the potential higher frequency of PE in SC cases, we conducted a retrospective study of our SC patients. METHODS: We assessed PE incidence, progression, and management in SC patients treated at our institute from 2006 to 2022. When available, we collected pre-SC repair CT scan data, calculating the Haller Index (HI) and Correction Index (CI) and compared them to a selected control group. RESULTS: Among 8 SC patients, 7 had concomitant PE (87.5%), varying in severity. PE management ranged from observation to thoracoplasty, depending on its degree. We observed a significant pre-operative CI difference between SC and control group patients (p < 0.00001). In the last two SC repair cases, we attempted concurrent PE prevention or treatment. CONCLUSION: Our findings suggest an underestimated association between PE and SC in the existing literature. SC patients may exhibit a predisposition to PE from birth, which may become more apparent with growth after SC repair. Consequently, PE prevention or treatment should be considered during SC repair procedures.

(F)utility of preoperative pulmonary function testing in pectus excavatum to assess severity.

PURPOSE: The utility of pulmonary function testing (PFT) in pectus excavatum (PE) has been subject to debate. Although some evidence shows improvement from preoperative to postoperative values, the clinical significance is uncertain. A high failure-to-completion rate for operative PFT (48%) was identified in our large institutional cohort. With such a high non-completion rate, we questioned the overall utility of PFT in the preoperative assessment of PE and sought to evaluate if other measures of PE severity or cardiopulmonary function could explain this finding. METHODS: Demographics, clinical findings, and results from cardiac MRI, PFT (spirometry and plethysmography), and cardiopulmonary exercise tests (CPET) were reviewed in 270 patients with PE evaluated preoperatively between 2015 and 2018. Regression modeling was used to measure associations between PFT completion and cardiopulmonary function. RESULTS: There were no differences in demographics, symptoms, connective tissue disorders, or multiple indices of pectus severity and cardiac deformation in PFT completers versus non-completers. While regression analysis revealed higher RVEF, LVEF, and LVEF-Z scores, lower RV-ESV/BSA, LV-ESV/BSA, and LV-ESV/BSA-Z scores, and abnormal breathing reserve in PFT completers vs. non-completers, these findings were not consistent across continuous and binary analyses. CONCLUSIONS: We found that PFT completers were not significantly different from non-completers in most structural and functional measures of pectus deformity and cardiopulmonary function. Inability to complete PFT is not an indicator of pectus severity.

Evaluating the web as a source of information for patients with chest wall deformities: insights into engagement and disparities.

BACKGROUND: Recent data highlight the internet's pivotal role as the primary information source for patients. In this study, we emulate a patient's/caregiver's quest for online information concerning chest deformities and assess the quality of available information. METHODS: We conducted an internet search using combination of the terms "pectus excavatum," "pectus excavatum surgery," "funnel chest," "pectus excavatum repair" and identified the first 100 relevant websites from the three most popular search engines: Google, Yahoo, and Bing. These websites were evaluated using the modified Ensuring Quality Information for Patients (EQIP) instrument. RESULTS: Of the 300 websites generated, 140 (46.7%) were included in our evaluation after elimination of duplicates, non-English websites, and those targeting medical professionals. The EQIP scores in the final sample ranged from 8 to 32/36, with a median score of 22. Most of the evaluated websites (32.8%) originated from hospitals, yet none met all 36 EQIP criteria. DISCUSSION: None of the evaluated websites pertaining to pectus excavatum achieved a flawless "content quality" score. The diverse array of websites potentially complicates patients' efforts to navigate toward high-quality resources. Barriers in accessing high-quality online patient information may contribute to disparities in referral, patient engagement, treatment satisfaction, and overall quality of life. LEVEL OF EVIDENCE: IV.

The Association of a Single Nucleotide Variant in COL5A1 to Early Onset Keratoconus and Pectus Excavatum-Convergence of Extracellular Matrix Pathologies.

Keratoconus is a bilateral ocular condition characterized by irregularities and the thinning of the cornea. Decreased central corneal thickness is a hallmark of the condition, and numerous genes have played a role in altering corneal thickness and the subsequent development of keratoconus. Variants in the structural and regulatory genes of the extracellular matrix have been highly associated with keratoconus, as well as with pectus excavatum, a chest wall deformity commonly seen in connective tissue disorders. This report describes a patient with a c.1720-11T>A intronic variant in the collagen-encoding gene, COL5A1, who was diagnosed with early-onset keratoconus and demonstrated a significant pectus excavatum. This report associates a COL5A1 variant with these seemingly unrelated phenotypic associations, further advancing the literature on the topic.

Impact of pectus excavatum on pulmonary function and exercise capacity in patients treated with 3D custom-made silicone implants.

BACKGROUND: Pectus excavatum (PE) is the most common congenital chest wall deformity, whose cardiopulmonary consequences are controversial. PE surgery is in our experience usually performed for aesthetic reasons. OBJECTIVES: The aim of this study was to evaluate the impact of PE on respiratory function and exercise capacity in patients with PE before patient-specific silicone implant correction. METHODS: This monocentric prospective study conducted at Toulouse University Hospital included sixty patients scheduled for custom-made silicone implants correction. Respiratory function (pulmonary function tests (FPTs)) and exercise capacity (VO2 max) were measured before surgery. RESULTS: Before surgery, no (0/60) restrictive lung disease was detected, with a mean total lung capacity (TLC) of 98.5% of predicted value (IC 95%; 80.4-137). Median VO2 max (n=56) was normal (89% predicted), with no cardiac limitation. CONCLUSION: In this cohort, PE had no impact on respiratory function nor exercise capacity. In patients without cardiac or respiratory effects of PE, silicone implants should be considered the preferred approach as it adequately addressed patients' main complaint of low self-esteem.

Pectus Excavatum and Risk of Right Ventricular Failure in Left Ventricular Assist Device Patients.

Background: Right ventricular failure (RVF) is a significant cause of morbidity and mortality in patients with a left ventricular assist device (LVAD). This study is aimed to investigate the influence of a pectus excavatum on early and late outcomes, specifically RVF, following LVAD implantation. Methods: A retrospective study was performed, that included patients with a HeartMate 3 LVAD at our tertiary referral center. The Haller index (HI) was calculated using computed tomography (CT) scan to evaluate the chest-wall dimensions. Results: In total, 80 patients (median age 57 years) were included. Two cohorts were identified: 28 patients (35%) with a normal chest wall (HI < 2.0) and 52 patients (65%) with pectus excavatum (HI 2.0-3.2), with a mean follow-up time of 28 months. Early ( ≤ 30 days) RVF and early acute kidney injury events did not differ between cohorts. Overall survival did not differ between cohorts with a hazard ratio (HR) of 0.47 (95% confidence interval (CI): 0.19-1.19, p = 0.113). Late ( > 30 days) recurrent readmission for RVF occurred more often in patients with pectus excavatum (p = 0.008). The onset of late RVF started around 18 months after implantation and increased thereafter in the overall study cohort. Conclusions: Pectus excavatum is observed frequently in patients with a LVAD implantation. These patients have an increased rate of readmissions and late RVF. Further investigation is required to explore the extent and severity of chest-wall abnormalities on the risk of RVF.

What Is the Appropriate Timing for Bar Removal After the Nuss Repair for Pectus Excavatum?

INTRODUCTION: The Nuss procedure for pectus excavatum requires that the sternal elevation be maintained by indwelling metal bars that are traditionally removed approximately 3 y after the repair. METHODS: A retrospective cohort study was conducted of all patients who underwent primary Nuss repair from 2007 to 2018 in two institutions and had a follow-up of at least 24 mo. Pectus bars had been left in place beyond 3 y in patients concerned over possible recurrence after bar removal. Structured interviews were held to assess pain, chest tightness, or other discomfort, and any adverse events related to pectus bars. Results were compared between patients in whom pectus bars were removed after 3 y (standard group) and those in whom bars were left in place longer (extended bar duration group). RESULTS: Two hundred and thirty-one patients (91% males, mean age 23.9 ± 8.3, mean Haller index 4.9 ± 2.3) were included. Bar duration was 30.6 ± 6.6 mo in the standard group (51 patients) versus 69.1 ± 26.3 mo in the extended group (180 patients). Some discomfort was reported by 81.6% in the standard group versus 62.9% in the extended group (P = 0.033), and discomfort occurring at least monthly or more often was only reported by 30% in the standard versus 30.3% in the extended group (P = 1.000). Quality of life improved in 92.6% of the standard group versus 94.7% of the extended group (P = 1.000). No significant adverse events were reported in either group. CONCLUSIONS: Our data suggest that an extended bar duration after the Nuss repair may not cause any adverse event nor negatively affect quality of life.

Parental Health Mindset Is Related to Preoperative Perceptions of Chest Wall Anomalies.

INTRODUCTION: Mindsets of health have been linked to different outcomes for patients with both surgical and medical conditions. A "growth" mindset, in which health is defined as malleable and subject to improvement, is associated with improved attitudes and outcomes when compared to a "fixed" mindset, in which health is defined as unchangeable. In pediatric surgery, parental growth mindsets of health have been correlated with better postoperative outcomes, including lower scores of anxiety and pain perceptions, for children. This was particularly notable in a study of postoperative outcomes for patients with pectus excavatum. In our current study, we extend our investigations to explore how health mindsets are associated with perceptions of chest wall anomalies before correction is undertaken. METHODS: Seventy-six patients (71 males, mean age 14 y, and 43 excavatum) and 18 parents were surveyed during a routine chest wall clinic visit. Demographic and clinical information as well as the Health Mindset Scale and Pectus Excavatum Evaluation Questionnaire were administered and collected pretreatment. RESULTS: Parental mindsets of health were significantly correlated with parent assessments of their children's chest pain, physical activity, and concerns about the life-time effect of the condition. A parental growth mindset was linked to lower scores of chest pain, higher ratings of activity, and lower overall level of concern. Furthermore, parental health mindsets also significantly correlated with children's own perceptions of their chest pain, physical activity, shortness of breath, and fatigue. Growth mindset also was linked to more positive ratings. CONCLUSIONS: Parental growth mindset was associated with more positive assessments of children's symptoms and limitations due to pectus deformities than fixed mindsets. Health mindset has been linked to patient perceptions of, and outcomes for, diabetes, renal disease, allergies, scoliosis, and obesity. Further study into parental and patient mindset correlation may help elucidate factors for bracing compliance, and perhaps to better prepare children and parents for corrective surgical procedures.

Erector Spinae Plane Block With Liposomal Bupivacaine: Analgesic Adjunct in Adult Pectus Surgery.

INTRODUCTION: Pain management may be challenging in patients undergoing pectus excavatum (PE) bar removal surgery. To enhance recovery, opioid sparing strategies with regional anesthesia including ultrasound-guided erector spinae plane block (ESPB) have been implemented. The purpose of this study was to evaluate the safety and efficacy of bilateral ESPB with a liposomal bupivacaine/traditional bupivacaine mixture as part of an enhanced patient recovery pathway. MATERIALS AND METHODS: A retrospective review of adult patients who underwent PE bar removal from January 2019 to December 2020 was performed. Perioperative data were reviewed and recorded. Patients who received ESPB were compared to historical controls (non-ESPB patients). RESULTS: A total of 202 patients were included (non-ESPB: 124 patients; ESPB: 78 patients). No adverse events were attributed to ESPB. Non-ESPB patients received more intraoperative opioids (milligram morphine equivalents; 41.8 ± 17.0 mg versus 36.7 ± 17.1, P = 0.05) and were more likely to present to the emergency department within 7 d postoperatively (4.8% versus 0%, P = 0.05) when compared to ESPB patients. No significant difference in total perioperative milligram morphine equivalents, severe pain in postanesthesia care unit (PACU), time from PACU arrival to analgesic administration, PACU length of stay, or postprocedure admission rates between groups were observed. CONCLUSIONS: In patients undergoing PE bar removal surgery, bilateral ESPB with liposomal bupivacaine was performed without complications. ESPB with liposomal bupivacaine may be considered as an analgesic adjunct to enhance recovery in patients undergoing cardiothoracic procedures but further prospective randomized clinical trials comparing liposomal bupivacaine to traditional local anesthetics with and without indwelling nerve catheters are necessary.

Consumer Wearables Define a Normative Recovery Trajectory Following the Modified Nuss Procedure.

INTRODUCTION: The modified Nuss procedure is an elective procedure associated with a lengthy recovery, uncontrolled pain, and risk of infrequent, yet life-threatening complications. The absence of objective measures of normative postoperative recovery creates uncertainty about the postdischarge period, which remains highly dependent on the patients' and their caregivers' expectations and management of recovery. We aimed to describe an objective-normative, physical activity recovery trajectory after the modified Nuss procedure, using step counts from the Fitbit. METHODS: This observational study enrolled children ≤18 y with pectus excavatum who underwent the modified Nuss procedure from 2021 to 2022. The Fitbit was worn for 21 postoperative days. Postdischarge outcomes and health-care utilization were evaluated. For patients without postoperative complications, piecewise linear regression analysis was conducted to generate a normative recovery trajectory model of daily step counts. RESULTS: Of 80 patients enrolled, 66 (86%) met eligibility criteria (mean age, 15.1 ± 1.3 y; 89.4% male, 62.1% non-Hispanic White). The mean number of telephone and electronic message encounters regarding concerns with the patient's recovery within 30 d postoperatively was 2.1 (standard deviation = 2.7). Ten patients (15.2%) returned to the emergency department (ED) within the 30-d postoperative period. Seven patients (10.6%) presented to the ED one time, and three patients (4.5%) presented to the ED twice. Thirty-day readmission rate was four patients (6.0%). Piecewise regression model showed that patients without complications steadily increased their daily step count on each postoperative day and plateaued on day 18. CONCLUSIONS: We have developed a normative recovery trajectory following the modified Nuss procedure using step count data collected by a consumer wearable device. This offers the potential to inform preoperative patient expectations and reduce avoidable health-care utilization through informed preoperative counseling, thus laying the ground work for the use of consumer wearable devices as a postdischarge remote monitoring tool.

Challenges of atrial fibrillation and atrial flutter ablation in patients with pectus excavatum.

Atrial fibrillation (AF) may be associated with chest wall abnormalities such as pectus excavatum (PE). Pulmonary vein isolation (PVI) has proven to be a useful strategy for radiofrequency catheter ablation (RFCA) of AF. However, the presence of chest wall abnormalities, such as pectus excavatum, imposes certain challenges during ablation due to the anatomic distortion that it causes. We highlight these challenges during ablation in this three-patient case series.

Continuous nerve block versus thoracic epidural analgesia for post-operative pain of pectus excavatum repair: a systematic review and meta-analysis.

Surgery to repair pectus excavatum (PE) is often associated with severe postoperative pain, which can impact the length of hospital stay (LOS). While thoracic epidural analgesia (TEA) has traditionally been used for pain management in PE, its placement can sometimes result in severe neurological complications. Recently, paravertebral block (PVB) and erector spinae plane block (ESPB) have been recommended for many other chest and abdominal surgeries. However, due to the more severe and prolonged pain associated with PE repair, it is still unclear whether continuous administration of these blocks is as effective as TEA. Therefore, we conducted this systematic review and meta-analysis to demonstrate the equivalence of continuous PVB and ESPB to TEA.
