Challenging Dogma by Skipping the Emergency Department Thoracotomy: A Propensity Score Matched Analysis of the Trauma Quality Improvement Database.

INTRODUCTION: Survival following emergency department thoracotomy (EDT) for patients in extremis is poor. Whether intervention in the operating room instead of EDT in select patients could lead to improved outcomes is unknown. We hypothesized that patients who underwent intervention in the operating room would have improved outcomes compared to those who underwent EDT. METHODS: We conducted a retrospective review of the Trauma Quality Improvement Program database from 2017 to 2021. All adult patients who underwent EDT, operating room thoracotomy (ORT), or sternotomy as the first form of surgical intervention within 1 h of arrival were included. Of patients without prehospital cardiac arrest, propensity score matching was utilized to create three comparable groups. The primary outcome was survival. Secondary outcomes included time to procedure. RESULTS: There were 1865 EDT patients, 835 ORT patients, and 456 sternotomy patients who met the inclusion criteria. There were 349 EDT, 344 ORT, and 408 sternotomy patients in the matched analysis. On Cox multivariate regression, there was an increased risk of mortality with EDT versus sternotomy (HR 4.64, P < 0.0001), EDT versus ORT (HR 1.65, P < 0.0001), and ORT versus sternotomy (HR 2.81, P < 0.0001). Time to procedure was shorter with EDT versus sternotomy (22 min versus 34 min, P < 0.0001) and versus ORT (22 min versus 37 min, P < 0.0001). CONCLUSIONS: There was an association between sternotomy and ORT versus EDT and improved mortality. In select patients, operative approaches rather than the traditional EDT could be considered.

Biomarkers of inflammation and coagulation after minimally invasive mitral valve surgery: a prospective comparison to conventional surgery.

OBJECTIVES: Minimally invasive cardiac surgery techniques are increasingly used but have longer cardiopulmonary bypass time, which may increase inflammatory response and negatively affect coagulation. Our aim was to compare biomarkers of inflammation and coagulation as well as transfusion rates after minimally invasive mitral valve repair and mitral valve surgery using conventional sternotomy. DESIGN: A prospective non-randomized study was performed enrolling 71 patients undergoing mitral valve surgery (35 right mini-thoracotomy and 36 conventional sternotomy procedures). Blood samples were collected pre- and postoperatively to assess inflammatory response. Thromboelastometry (ROTEM) was performed to assess coagulation, and transfusion rates were monitored. RESULTS: The minimally invasive group had longer cardiopulmonary bypass times compared to the sternotomy group: 127 min ([115-146] vs 79 min [65-112], p < 0.001) and were cooled to a lower temperature during cardiopulmonary bypass, 34 °C vs 36 °C (p = 0.04). IL-6 was lower in the minimally invasive group compared to the conventional sternotomy group when measured at the end of the surgical procedure, (38 [23-69] vs 61[41-139], p = 0.008), but no differences were found at postoperative day 1 or postoperative day 3. The transfusion rate was lower in the minimally invasive group (14%) compared to full sternotomy (35%, p = 0.04) and the chest tube output was reduced, (395 ml [190-705] vs 570 ml [400-1040], p = 0.04). CONCLUSIONS: Our data showed that despite the longer use of extra corporal circulation during surgery, minimally invasive mitral valve repair is associated with reduced inflammatory response, lower rates of transfusion, and reduced chest tube output.

Superficial parasternal intercostal plane blocks in cardiac surgery: a systematic review and meta-analysis.

PURPOSE: Traditional multimodal analgesic strategies have several contraindications in cardiac surgery patients, forcing clinicians to use alternative options. Superficial parasternal intercostal plane blocks, anesthetizing the anterior cutaneous branches of the thoracic intercostal nerves, are being explored as a straightforward method to treat pain after sternotomy. We sought to evaluate the literature on the effects of superficial parasternal blocks on pain control after cardiac surgery. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). We searched MEDLINE, Embase, CENTRAL, and Web of Science databases for RCTs evaluating superficial parasternal intercostal plane blocks in adult patients undergoing cardiac surgery via midline sternotomy published from inception to 11 March 2022. The prespecified primary outcome was opioid consumption at 12 hr. The risk of bias was assessed with the Cochrane Collaboration Risk of Bias Tool, and the quality of evidence was evaluated using the grading of recommendations, assessments, development, and evaluations. Outcomes were analyzed with a random-effects model. All subgroups were prespecified. RESULTS: We reviewed 1,275 citations. Eleven RCTs, comprising 756 patients, fulfilled the inclusion criteria. Only one study reported the prespecified primary outcome, precluding the possibility of meta-analysis. This study reported a reduction in opioid consumption (-11.2 mg iv morphine equivalents; 95% confidence interval [CI], -8.2 to -14.1) There was a reduction in opioid consumption at 24 hr (-7.2 mg iv morphine equivalents; 95% CI, -5.6 to -8.7; five trials; 436 participants; moderate certainty evidence). All five studies measuring complications reported that none were detected, which included a sample of 196 blocks. CONCLUSION: The literature suggests a potential benefit of using superficial parasternal blocks to improve acute postoperative pain control after cardiac surgery via midline sternotomy. Future studies specifying dosing regimens and adjuncts are required. STUDY REGISTRATION: PROSPERO (CRD42022306914); first submitted 22 March 2022.

RéSUMé: OBJECTIF: Il existe plusieurs contre-indications aux stratégies analgésiques multimodales traditionnelles chez la patientèle de chirurgie cardiaque, ce qui oblige les clinicien·nes à se tourner vers d'autres options. Les blocs des plans intercostaux parasternaux superficiels, anesthésiant les branches cutanées antérieures des nerfs intercostaux thoraciques, sont l'une des méthodes simples actuellement explorées pour traiter la douleur après une sternotomie. Nous avons cherché à évaluer la littérature sur les effets des blocs parasternaux superficiels sur le contrôle de la douleur après une chirurgie cardiaque. MéTHODE: Nous avons réalisé une revue systématique et une méta-analyse des études randomisées contrôlées (ERC). Nous avons fait des recherches dans les bases de données MEDLINE, Embase, CENTRAL et Web of Science pour en tirer les ERC évaluant les blocs des plans intercostaux parasternaux superficiels chez les patient·es adultes bénéficiant d'une chirurgie cardiaque par sternotomie médiane publiées depuis leur création jusqu'au 11 mars 2022. Le critère d'évaluation principal préspécifié était la consommation d'opioïdes à 12 heures. Le risque de biais a été évalué à l'aide de l'outil Cochrane Collaboration Risk of Bias, et la qualité des données probantes à l'aide de l'outil GRADE. Les résultats ont été analysés à l'aide d'un modèle à effets aléatoires. Tous les sous-groupes étaient préspécifiés. RéSULTATS: Nous avons examiné 1275 citations. Onze ERC, comprenant 756 patient·es, remplissaient les critères d'inclusion. Une seule étude a rapporté le critère d'évaluation principal préspécifié, ce qui a exclu la possibilité d'une méta-analyse. Cette étude a rapporté une réduction de la consommation d'opioïdes (−11,2 mg équivalents de morphine iv; intervalle de confiance [IC] à 95 %, −8,2 à −14,1). Il y a eu une réduction de la consommation d'opioïdes à 24 heures (−7,2 mg équivalents de morphine iv; IC 95 %, −5,6 à −8,7; cinq études; 436 participant·es; données probantes de certitude modérée). Les cinq études mesurant les complications ont rapporté qu'aucune complication n'avait été détectée, en incluant un échantillon de 196 blocs. CONCLUSION: La littérature suggère un avantage potentiel de l'utilisation de blocs parasternaux superficiels pour améliorer le contrôle de la douleur postopératoire aiguë après une chirurgie cardiaque par sternotomie médiane. Des études futures précisant les schémas posologiques et les adjuvants sont nécessaires. ENREGISTREMENT DE L'éTUDE: PROSPERO (CRD42022306914); soumis pour la première fois le 22 mars 2022.

Minimally Invasive Approach versus Sternotomy for Cardiac Surgery in Jehovah's Witness Patients.

OBJECTIVE: To evaluate the outcomes of minimally invasive cardiac surgery (MICS) compared with the sternotomy approach for Jehovah's Witness (JW) patients who cannot receive blood transfusions DESIGN: This was a retrospective observational study. SETTING: The study was conducted at a specialized cardiovascular intervention and surgery institute. PARTICIPANTS: The study cohort comprised JW patients undergoing cardiac surgery between September 2016 and July 2022. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Patients (n = 63) were divided into MICS (n = 19) and sternotomy (n = 44) groups, and clinical outcomes were analyzed. There was no difference in types of operation except coronary bypass grafting (n = 1 [5.3%] in the MICS group v n = 20 [45.5%] in the sternotomy group; p = 0.005). There were no between-group differences in early mortality and morbidities. Overall survival did not differ significantly during the follow-up period (mean, 43.9 ± 24.4 months). The amount of chest tube drainage was significantly lower in the MICS group on the first postoperative day (mean, 224.0 ± 122.7 mL v 334.0 ± 187.0 mL in the sternotomy group; p = 0.022). The mean hemoglobin level was significantly higher in the MICS group on the day of operation (11.7 ± 1.3 mg/dL v 10.6 ± 2.0 mg/dL in the sternotomy group; p = 0.042) and the first postoperative day (12.3 ± 1.8 mg/dL v 11.2 ± 1.9 mg/dL; p = 0.032). CONCLUSIONS: MICS for JW patients showed favorable early outcomes and mid-term survival compared to conventional sternotomy. MICS may be a viable option for JW patients who decline blood transfusions.

Clinical Outcomes of Erector Spinae Plane Block for Midline Sternotomy in Cardiac Surgery: A Systematic Review and Meta-Analysis.

OBJECTIVES: To evaluate the benefit of single-shot erector spinae plane block (ESPB) on pain at postoperative hours 4 and 12, duration of mechanical ventilation, hospital length of stay, intensive care unit (ICU) length of stay, cumulative postoperative opioid usage, and incidence of postoperative nausea and vomiting (PONV) after cardiac surgery via sternotomy DESIGN: A systematic review and meta-analysis of randomized controlled trials and prospective clinical trials. SETTING: Studies were identified through the search of PubMed and EMBASE on July 19, 2023. PARTICIPANTS: Adults and children undergoing cardiac surgery via sternotomy. INTERVENTIONS: Single-shot ESPB versus standard-of-care analgesia. MEASUREMENTS AND MAIN RESULTS: A systematic review and meta-analysis of 10 studies (N = 695 patients). The single-shot ESPB arm exhibited statistically significant reductions in pain score at postoperative hour 4 (standardized mean difference [SMD] -2.95, 95% CI -5.86 to -0.04, p = 0.0466), duration of mechanical ventilation (SMD -1.23, 95% CI -2.21 to -0.24, p = 0.0145), cumulative postoperative opioid usage (SMD -1.48, 95% CI -2.46 to -0.49, p = 0.0033), and PONV incidence (risk ratio 0.4358, 95% CI 0.2105-0.9021, p = 0.0252). The single-shot ESPB arm did not exhibit a statistically significant reduction in pain score at postoperative hour 12, length of hospital stay, and length of ICU stay. CONCLUSIONS: Single-shot ESPB improves near-term clinical outcomes in patients undergoing cardiac surgery via sternotomy. More randomized controlled trials are needed to validate these findings.

Comparison of Multiple Injection Costotransverse Block and Erector Spinae Plane Block for Post-Sternotomy Pain Relief in Pediatric Patients Undergoing Cardiac Surgery: A Prospective Randomized Comparative Study.

OBJECTIVE: The aim of this study was to evaluate the efficacy of ultrasound-guided multiple injection costotransverse block (MICB) and compare it with erector spinae plane block (ESPB) for poststernotomy pain relief in pediatric cardiac surgical patients. DESIGN: A prospective, randomized, double-blind, comparative study. SETTING: At a single institution tertiary referral cardiac center. PARTICIPANTS: A total of 90 children with acyanotic congenital heart disease requiring surgery via sternotomy. INTERVENTIONS: Children were allocated randomly to 1 of the 3 following groups: ESPB (group 1), MICB (group 2), or Control (group 3). Participants in groups 1 and 2 received 4 mg/kg of 0.2% ropivacaine for bilateral ultrasound-guided block after induction of anesthesia. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl/tramadol was used for rescue analgesia. MEASUREMENTS AND MAIN RESULTS: The modified objective pain score (MOPS) was evaluated at 0, 1, 2, 4, 6, 8, 10, and 12 hours postextubation. After all exclusions, 84 patients were analyzed. The MOPS score was found to be significantly lower in ESPB and MICB groups compared to the control group until 10 hours postextubation (p < 0.05), with no statistically significant difference at the 12th hour (p = 0.2198). The total intraoperative fentanyl consumption (p = 0.0005), need for fentanyl supplementation on incision (p < 0.0001), and need for rescue opioid requirement in the postoperative period (p = 0.034) were significantly lower in both the ESPB and MICB groups than the control group. There were no statistically significant differences in both primary and secondary outcomes between the ESPB and MICB groups. CONCLUSION: Ultrasound-guided MICB was effective and comparable to ESPB for post-sternotomy pain management in pediatric cardiac surgical patients.

Comparison of Erector Spinae Plane Block and Pectointercostal Facial Plane Block for Enhanced Recovery After Sternotomy in Adult Cardiac Surgery.

OBJECTIVES: This study aimed to investigate and compare the effects of the pectointercostal fascial plane block (PIFPB) and the erector spinae plane block (ESPB) on enhancing the recovery of patients who undergo cardiac surgery. DESIGN: A randomized, controlled, double-blinded study. SETTING: The operating rooms and intensive care units of university hospitals. PARTICIPANTS: One hundred patients who were American Society of Anesthesiologists class II to III aged 18-to-70 years scheduled for elective cardiac surgery. INTERVENTIONS: Patients were randomly assigned to undergo either ultrasound-guided bilateral PIFPB or ESPB. MEASUREMENTS AND MAIN RESULTS: Patients shared comparable baseline characteristics. Time to extubation, the primary outcome, did not demonstrate a statistically significant difference between the groups, with median (95% confidence interval) values of 115 (90-120) minutes and 110 (100-120) minutes, respectively (p = 0.875). The ESPB group had a statistically significant reduced pain score postoperatively. The median (IQR) values of postoperative fentanyl consumption were statistically significantly lower in the ESPB group than in the PIFPB group (p < 0.001): 4 (4-5) versus 9 (9-11) µg/kg, respectively. In the ESPB group, the first analgesia request was given 4 hours later than in the PIFPB group (p < 0.001). Additionally, 12 (24%) patients in the PIFPB group reported nonsternal wound chest pain, compared with none in the ESPB group. The median intensive care unit length of stay for both groups was 3 days (p = 0.428). CONCLUSIONS: Erector spinae plane block and PIFPB were found to equally affect recovery after cardiac surgery, with comparable extubation times and intensive care unit length of stay.

Deep Parasternal Intercostal Plane Block for Intraoperative Pain Control in Cardiac Surgical Patients for Sternotomy: A Prospective Randomized Controlled Trial.

OBJECTIVES: Sternotomy pain is common after cardiac surgery. The deep parasternal intercostal plane (DPIP) block is a novel technique that provides analgesia to the anterior chest wall. The aim of this study was to investigate the analgesic effect of bilateral DPIP blocks on intraoperative pain control in cardiac surgery. DESIGN: This is a double-blinded, prospective randomized controlled trial (Oct 2020-Dec 2022). SETTINGS: This study was conducted in a single institution, which is an academic university hospital. PARTICIPANTS: Eighty-six elective cardiac surgical patients with median sternotomy were recruited. INTERVENTIONS: Patients were randomly divided into DPIP or control group. Either 20ml 0.25% levobupivacaine or 0.9% normal saline was injected for the DPIP under ultrasound guidance after induction of general anaesthesia. MEASUREMENTS AND MAIN RESULTS: The primary outcome was intraoperative opioids consumption and hemodynamic changes at sternotomy. Secondary outcomes included postoperative morphine consumption, postoperative pain and time to tracheal extubation. Intraoperative opioids requirement was reduced from a median (IQR) intravenous morphine equivalence of 21.4mg (13.8-24.3mg) in control group to 9.5mg (7.3-11.2mg) in the DPIP group (P<0.001). Hemodynamic parameters were more stable in DPIP group at sternotomy, as evidenced by lower percentage increase in systolic, diastolic and mean arterial blood pressure from baseline. No difference was observed in time to tracheal extubation, postoperative morphine consumption, postoperative pain score and spirometry. CONCLUSIONS: Bilateral DPIP block provides effective intraoperative analgesia and opioid-sparing. It may be included as part of the multimodal analgesia for enhanced recovery in cardiac surgery.

Incidence and Factors Associated With Post-Sternotomy Pain Syndrome in the National Heart Institute, Malaysia.

OBJECTIVE: To determine the incidence of poststernotomy pain syndrome (PSPS) after open cardiac surgery in 2021. To determine characteristics and assess the severity of symptoms in patients diagnosed with PSPS. To identify factors that can be associated with patients who were positive for PSPS. DESIGN AND METHODOLOGY: This study used a retrospective observational approach. Logistic regression analysis was employed to identify factors associated with the positive group. SETTING: This study included all adult patients who underwent open cardiac surgery at the National Heart Institute, Malaysia, in 2021. PARTICIPANTS: A total of 1,395 patients were enrolled. INTERVENTIONS: The study involved conducting phone interviews to assess the presence of PSPS, followed by administering the Brief Pain Inventory questionnaire in the positive group to identify characteristics and severity of chronic pain. MEASUREMENTS AND MAIN RESULTS: The incidence of PSPS after open cardiac surgery in 2021 was 20.35%. A total of 17.7% of patients reported that pain affected their daily activities, sleep, or emotions. Univariate analysis identified factors associated with PSPS, including age <60 years old, body mass index >30 kg/m2, history of previous percutaneous coronary intervention, ejection fraction <50%, the absence of chronic kidney disease (CKD), and internal mammary artery harvesting (p < 0.05). Multivariate analysis revealed that 4 independent factors were associated with PSPS: age <60 years old, history of previous percutaneous coronary intervention, ejection fraction <50%, and the absence of CKD (as compared with CKD) (p < 0.05). CONCLUSIONS: Poststernotomy pain syndrome is a complex issue affected by various factors. Although the pain score may not be as severe as previously believed, it remains crucial to recognize PSPS because a significant proportion of patients are affected.

Biomechanical comparison of bone staple fixation methods with suture material for median sternotomy closure using 3D-printed bone models.

AIM: To compare the biomechanical properties of three different sternal closure techniques in a 3D-printed bone model of a sternum from a 30-kg dog. METHODS: Median sternotomy was performed on a total of 90 three-dimensional (3D) copies of a polycarbonate (PC) model of a sternum, generated from the CT images of the sternum of a 30-kg German Shepherd dog. Three different methods were used to repair the sternotomies: polydioxanone suture (group PDS, n = 30), stainless steel bone staples (group SS, n = 30), and nitinol bone staples (group NS, n = 30). Each repair method was tested by applying tensile force in one of three ways (longitudinally, laterally, or torsionally) resulting in a sample size of n = 10 for each repair method-loading combination. In all experiments, the loads at 1-mm and 2-mm gap formation, failure, and the displacement at the failure point were measured. RESULTS: In lateral distraction and longitudinal shear tests, NS and SS staple repairs required application of significantly greater force than PDS across all displacement criteria (1 and 2 mm). NS exhibited significantly greater failure load than PDS. In torsion tests, NS required significantly greater application of force compared to SS or PDS at all displacement criteria (1 and 2 mm) and exhibited a greater failure load than PDS. In terms of displacement at failure point, PDS suture showed more displacement than SS or NS across all experiments (laterally, longitudinally, torsionally). CONCLUSIONS: In this study, bone staples were mechanically superior to PDS suture in median sternotomy closure using 3D-printed bone model in terms of 1-mm, 2-mm displacement loads, and displacement at failure. NS had a higher failure load than PDS under lateral, longitudinal, and torsional distraction. CLINICAL RELEVANCE: These study results imply that bone staples can be considered as an alternative surgical method for median sternotomy closure in dogs.

Risk factors for sternal wound infection after median sternotomy: A nested case-control study and time-to-event analysis.

Although potential risk factors for sternal wound infection (SWI) have been extensively studied, the onset time of SWI and different risk factors for superficial and deep SWI were rarely reported. This nested case-control study aims to compare the onset time and contributors between superficial and deep SWI. Consecutive adult patients who underwent cardiac surgery through median sternotomy in a single center from January 2011 to January 2021 constituted the cohort. The case group was those who developed SWI as defined by CDC and controls were matched 6:1 per case. Kaplan-Meier analysis, LASSO and univariate and multivariate Cox regressions were performed. A simple nomogram was established for clinical prediction of the risk of SWI. The incidence of SWI was 1.1% (61 out of 5471) in our cohort. Totally 366 controls were matched to 61 cases. 26.2% (16 of 61) SWI cases were deep SWI. The median onset time of SWI was 35 days. DSWI had a longer latency than SSWI (median time 46 days vs. 32 days, p = 0.032). Kaplan-Meier analyses showed different time-to-SWI between patients with and without DM (p = 0.0011) or MI (p = 0.0019). Multivariate Cox regression showed that BMI (HR = 1.083, 95% CI: 1.012-1.116, p = 0.022), DM (HR = 2.041, 95% CI: 1.094-3.805, p = 0.025) and MI (HR = 2.332, 95% CI: 1.193-4.557, p = 0.013) were independent risk factors for SWI. Superficial SWI was only associated with BMI (HR = 1.089, 95% CI: 1.01-1.175, p = 0.027), while deep SWI was associated with DM (HR = 3.271, 95% CI: 1.036-10.325, p = 0.043) and surgery time (HR = 1.004, 95% CI: 1.001-1.008, p = 0.027). The nomogram for SWI prediction had an AUC of 0.67, good fitness and clinical effectiveness as shown by the calibration curve and decision curve analyses. BMI, DM and MI were independent risk factors for SWI. DSWI had a longer latency and different risk factors compared to SSWI. The nomogram showed a fair performance and good effectiveness for the clinical prediction of SWI.

[Epicardial Pacemaker Infection Treated by Leads Removal via Re-sternotomy:Report of a Case].

A 69-year-old woman was diagnosed with a pacemaker infection after generator-exchange. Eight years ago, she underwent mitral and tricuspid valve replacement and had biventricular pacing with three pairs of epicardial leads placed in the right atrium, right ventricle, and left ventricle for left ventricular dysfunction. Skin perforation due to infection was detected 1 month after generator-exchange. At first, antibiotic treatment, generator-re-exchange, and pocket repositioning surgery were performed. Following all these failed attempts, a temporary pacemaker was placed, the infected generator was removed, and the lead was cut short. Eight days later, new intravenous caradiac resynchronization therapy pacemaker (CRT-P) implantation was performed. However, despite the repeat debridement, infection at the lead stumps recurred. Moreover, plain chest computed tomography (CT) revealed an abscess around the leads in the anterior mediastinum. Eventually, leads were removed under extracorporeal circulation via re-sternotomy. Postoperative course was uneventful, and she has been doing well without recurrence of infection for 6 years after operation.

[Mitral valve surgery via minimally invasive and conventional access]. / Mitral'naya khirurgiya iz mini- i traditsionnogo dostupov.

OBJECTIVE: To compare the immediate results of mini-thoracotomy and sternotomy in patients with mitral valve disease. MATERIAL AND METHODS: The study included 52 patients who underwent mitral valve surgery (25 cases - mini-thoracotomy, 27 cases - sternotomy). RESULTS: Aortic cross-clamping time was significantly longer in sternotomy compared to mini-thoracotomy group - 110 vs 94 min (p=0.03). Ventilation time was also significantly longer in the sternotomy group (12 vs. 8 hours, p=0.01). Postoperative morbidity was similar (postoperative wound infection, neurological complications, coronavirus disease, overall in-hospital mortality). CONCLUSION: In addition to cosmetic effect, minimally invasive approach in mitral valve surgery has some other advantages including less duration of aortic cross-clamping and mechanical ventilation, availability of reconstructive interventions due to better exposition of the mitral valve and subvalvular structures.

[Postoperative sternomediastinitis: morphology of lesion, treatment strategy]. / Posleoperatsionnyi sternomediastinit: morfologiya porazheniya, taktika lecheniya.

OBJECTIVE: To analyze bone tissue damage at different stages of disease (El Oakley classification), treatment options for each clinical situation and results after each approach. MATERIAL AND METHODS: There were 45 patients with wound complications after cardiac surgery between October 2022 and September 2023. Thirty-eight (84.4%) patients underwent CABG, 7 (15.6%) patients - heart valve or aortic surgery. Mean age of patients was 68.1±10.3 years. There were 35 men (77.8%) and 10 women (22.2%). The first type was found in 11 (24.5%) patients, type 2-3 - 19 (42.2%), type 4 - 4 (8.8%), type 5 - 11 (24.5%) patients. RESULTS: Systemic inflammatory response syndrome was observed in 7 (36.8%) persons of the 1st group, 14 (73.7%) ones of the 2nd group, 4 (100%) patients of the 3rd group and 2 (18.2%) patients of the 4th group. C-reactive protein and procalcitonin increased in all patients with the highest values in groups 2 and 3. Redo soft tissue inflammation occurred in all groups after treatment. Mean incidence was 25%. Two (10.5%) patients died in the 2nd group and 1 (25%) patient in the 3rd group. CONCLUSION: The modern classification of sternomediastinitis does not fully characterize severity of disease in a particular patient. Simultaneous debridement with wound closure demonstrates acceptable mortality (within 10%). The highest mortality rate was observed in patients with diffuse lesions of the sternum. Less aggressive treatment approaches are possible for stable anterior chest wall.

Minimally Invasive Trans-Axillary versus Full Sternotomy Mitral Valve Repair: A Propensity Score-Matched Analysis on Mid-Term Outcomes.

Background and Objectives: Minimally invasive cardiac surgery is an established approach for the treatment of heart valve pathologies and is associated with excellent technical and early postoperative outcomes. Data from medium- and long-term longitudinal evaluation of patients who underwent mitral valve repair (MVr) through transaxillary approach (TAxA) are still lacking. The aim of this study is to investigate mid-term results in patients who underwent TAxA MVr. Materials and Methods: Prospectively collected data of patients who underwent first-time MVr for MV regurgitation between 2017 and 2022, were reviewed. A total of 308 patients received TAxA, while in 220 cases, traditional full sternotomy (FS) was performed. Concomitant aortic and coronary artery bypass grafting (CABG) procedures, infective endocarditis or urgent operations were excluded. A propensity match (PS) analysis was used to overcome preoperative differences between the populations. Follow-up data were retrieved from outpatients' clinic, telephone calls and municipal administration records. Results: After PS-matching, two well-balanced cohorts of 171 patients were analysed. The overall 30-day mortality rate was 0.6% in both cohorts. No statistical difference in postoperative complications was reported. TAxA cohort experienced earlier postoperative extubation (p < 0.001) with a higher rate of extubation performed in the operating theatre (p < 0.001), shorter intensive care unit (ICU) stay (p < 0.001), and reduced hospitalization with 51% of patients discharged home (p < 0.001). Estimated survival at 5 years was 98.8% in TAxA vs. 93.6% in FS cohort (Log rank p = 0.15). The cumulative incidence of reoperation was 2.6% and 4.4% at 5 years, respectively, in TAxA and FS cohorts (Gray test p = 0.49). Conclusions: TAxA approach for MVr was associated with low rates of in-hospital mortality and major postoperative complications being furthermore associated with shorter mechanical ventilation time, shorter ICU stay and reduced hospitalization with a higher rate of patients able to be discharged home. At mid-term, TAxA was associated with excellent survival and low rate of MV reoperation.

[High-tone therapy in complex rehabilitation of patients with post-sternotomy syndrome after coronary artery bypass surgery. (Open-label, prospective, randomized controlled trial)]. / Vysokotonovaya terapiya v kompleksnoi reabilitatsii bol'nykh s poststernotomicheskim sindromom posle aortokoronarnogo shuntirovaniya. (Otkrytoe prospektivnoe randomizirovannoe kontroliruemoe issledovanie).

INTRODUCTION: At present it remains relevant to develop new rehabilitation technologies for patients with circulatory system diseases who have undergone a cardiac surgery to restore the functions of the cardiorespiratory system more quickly, improve physical and mental health, and prevent the development of the atherosclerotic process. AIM: To study the effectiveness and safety of the new rehabilitation technology for the inpatient stage of medical rehabilitation of patients with post-sternotomy syndrome after coronary artery bypass surgery (CABS) using high-tone therapy. MATERIAL AND METHODS: The study included 85 men (the average age was 56.8±2.46 years old) with post-sternotomy syndrome after CABS. They were divided into two groups by simple randomization: the first/main (42 patients) and the second/control (43 patients). The control group of the patients had a standard rehabilitation complex; the main group was additionally prescribed a high-tone therapy according to a local method. The immediate results of the treatment were assessed by the dynamics of the clinical picture, the six-minute walk test, respiratory function, echocardiography, the level of cytokines, C-reactive protein and natriuretic peptide (NT-proBNP); distant - by QOL endpoints (questionnaire MOS SF-36). RESULTS: The groups of the patients were comparable in all baseline parameters. After the course of the procedures in the main group of patients there were positive reliable (p<0.05-0.001) shifts in clinical (pain, shortness of breath, general weakness), functional (forced expiratory vital capacity, forced expiratory volume1, effusion separation) and laboratory parameters (leukocytes, interleukin-2 and 10, NT-proBNP). The intergroup analysis of long-term results registered significant (p<0.05) differences in the QOL of patients in the main group by subscales: the role of somatic problems, vitality and mental health. Compliance to the III stage of medical rehabilitation (outpatient/home) was noted with 95.2% of the patients in the first group and 93.0% in the second. CONCLUSION: The additional appointment of a high-tone therapy to the rehabilitation standard for the patients with post-sternotomy syndrome after CABS significantly improves the immediate and long-term results of the treatment (QOL) contributing to a more pronounced reverse development of inflammatory and edematous syndromes, an increase in physical activity and psychosomatic health. The absence of adverse reactions with all the patients indicates the safety of rehabilitation complexes.

Post-sternotomy movement strategies in adults: a scoping review.

AIMS: Post-sternotomy movement strategies for adults should be an evidence-informed approach and support a safe, independent return to daily activity. Recent new movement strategies have emerged. The aim of this scoping review was to identify and summarize the available evidence for post-sternotomy movement strategies in adults. METHODS AND RESULTS: The electronic databases searched included MEDLINE, Embase, Sport Discus, CINAHL, Academic Search Complete, the Cochrane Library, Scopus, and PEDro. The search did not have a date limit. After 2405 duplicates were removed, 2978 records were screened, and 12 were included; an additional 2 studies were identified through reference searching for a total of 14 included studies. A data extraction table was used, and the findings are summarized in a tabular and narrative form. Three post-sternotomy movement strategies were identified in the literature: sternal precautions (SP), modified SP, and Keep Your Move in the Tube (KYMITT™). The authors suggested that the practice of SP was based on expert opinion and not founded in evidence. However, the evidence from the identified articles suggested that new movement strategies are safe and allow patients to choose an increased level of activity that promotes improved functional status and confidence. CONCLUSION: More prospective cohort studies and multi-centred randomized control trials are needed; however, the current evidence suggests that modified SP and KYMITT™ are as safe as SP and can promote a patient-centred approach.

Re-sternotomy in complex aortic surgery: careful individualized planning for a safe opening.

An increasing number of patients have required cardiac reoperations in recent decades, and this trend is expected to continue. Hence, re-sternotomy is and will be a common practice in high-volume centres. Re-sternotomy in complex aortic reinterventions carries a high risk of injuring major vascular and heart structures. To avoid catastrophic injuries, preoperative planning and case individualization are essential to minimize complications. Designing a safe and tailored strategy for each patient is believed to have an impact on postoperative outcomes. The arterial cannulation site, the need for hypothermia, left ventricle decompression and the use of an aortic occlusion balloon catheter are some of the preoperative decisions that must be made on a case-by-case basis to ensure adequate brain and visceral perfusion and to minimize major bleeding and circulatory interruption in case of re-entry injury.

Repair of Tracheoesophageal Fistula via Median Sternotomy Approach.

Tracheoesophageal fistula (TEF) and esophageal atresia (EA) are rare congenital anomalies occurring in approximately 1 in 2500 to 3500 neonates. We present a neonatal patient diagnosed with EA/TEF in conjunction with pulmonary agenesis requiring definitive repair via median sternotomy. The child was born at 33 weeks gestational age with post-delivery respiratory distress necessitating intubation. A nasogastric tube was unable to be passed. After subsequent imaging, TEF and pulmonary agenesis were diagnosed. During planned staged repair with ligation of TEF via standard right thoracotomy approach, significant ventilatory compromise was encountered. Due to concern for ventilatory compromise and anatomical variance limiting visualization, a median sternotomy approach was utilized for definitive repair. This exposure and repair were successful and may be considered for cases with complex pulmonary malformation limiting standard thoracotomy. To our knowledge, this is only the second reported case of a successful TEF/EA repair using a median sternotomy approach.
