ABSTRACT
OBJECTIVES: The aim of this study was to assess predictors of BP and hypertension and relations between BP and LV mass in a population-based retrospective study of repaired isolated coarctation of aorta. METHODS: We collected follow-up data until 2018 of 284/304 (93%) patients with coarctation treated by surgery (n = 235) or balloon angioplasty/stent (n = 37/12) in our unit 2000-2012. Systolic hypertension was defined as systolic BP (SBP) z-score ≥+2 standard deviation (SD) or regular use of BP medication. LV hypertrophy was defined as LV mass z-score ≥+2 SD or LV mass index g/m2.7 ≥95th percentile. RESULTS: The median (25-75th percentiles) follow-up time and age at follow-up were 9.7 years (6.9-13.2) and 11.8 years (7.9-16.0), respectively. Age at first procedure (P = 0.011) and systolic arm-leg-gradient (P = 0.007) were positively and transverse arch (P = 0.007) and isthmus diameter (P = 0.001) z-scores at follow-up were negatively associated with SBP z-score adjusted for age at follow-up and need for reintervention for coarctation. Systolic hypertension was present in 53/284 (18.7%) and related with increasing age at first procedure (median 33.2 vs 0.6 months; P < 0.001) and arm-leg-gradient at follow-up (mean ± SD, -0.3 ± 14.6 vs -6.4 ± 11.6 mmHg; P = 0.047) adjusted for reintervention for coarctation and age at follow-up. LV hypertrophy was present in 20/227 (9.3%) and related with SBP z-score. CONCLUSIONS: Higher SBP and hypertension in repaired coarctation of aorta are related with increasing age at first procedure and arm-leg-gradient at follow-up. Transverse arch and isthmus diameters at follow-up are inversely related with SBP.

BACKGROUND: Drugs with histone deacetylase inhibitory (HDACi) properties have shown to decrease prostate cancer (PCa) cell growth in vitro. METHODS: A cohort of 9261 PCa cases from the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC) was used to evaluate prostate cancer-specific mortality in men using anti-epileptic drugs (AEDs). A national subscription database was used to obtain information on medication use. Cox regression with AED use as a time-dependent variable was used to analyse prostate cancer mortality in men using AEDs compared to non-users, and in men using HDACi AEDs compared to users of other AEDs. The analysis was adjusted for age, screening trial arm, PCa risk group, primary treatment of PCa, Charlson co-morbidity score and concomitant use of other drugs. RESULTS: The use of AEDs, in general, was associated with an increased risk of PCa death. The use of HDACi AEDs was not significantly associated with decreased PCa mortality compared to use of other AEDs (HR 0.61, 95% CI 0.31-1.23). CONCLUSIONS: AED usage is associated with elevated PCa mortality compared to non-users, likely reflecting the differences between men with epilepsy and those without. No benefit was observed from HDACi drugs compared to other AEDs.

Background: Cardiopulmonary bypass (CPB) may lead to tissue hypoxia, inflammatory response, and risk for acute kidney injury (AKI). We evaluated the prevalence of AKI and inflammatory response in neonates undergoing heart surgery requiring CPB with or without antegrade cerebral perfusion (ACP). Methods: Forty neonates were enrolled. The patients were divided into two groups depending on the use of ACP. AKI was classified based on the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Inflammatory response was measured using plasma concentrations of interleukins 6 (IL-6) and 10 (IL-10), white blood cell count (WBC), and C-reactive protein (CRP). Results: Eight patients (20%) experienced AKI: five (29%) in the ACP group and three (13%) in the non-ACP group (P = 0.25). Postoperative peak plasma creatinine and urine neutrophil gelatinase-associated lipocalin were significantly higher in the ACP group than in the non-ACP group [46.0 (35.0-60.5) vs 37.5 (33.0-42.5), P = 0.044 and 118.0 (55.4-223.7) vs 29.8 (8.1-109.2), P = 0.02, respectively]. Four patients in the ACP group and one in the non-ACP group required peritoneal dialysis (P = 0.003). Postoperative plasma IL-6, IL-10, and CRP increased significantly in both groups. There were no significant differences between the ACP and non-ACP groups in any of the inflammatory parameters measured. Conclusions: No significant difference in the AKI occurrence or inflammatory response related to CPB modality could be found. In our study population, inflammation was not the key factor leading to AKI. Due to the limited number of patients, these findings should be interpreted with caution.

Antiepileptic drugs (AEDs) with histone deacetylase (HDAC) inhibitor properties decrease prostate cancer (PCa) cell proliferation in vitro. A population-based cohort of 78 615 men was used to evaluate the risk of PCa among users of AEDs. Study population was linked to the Finnish national prescription database to obtain information on individual medication reimbursements in 1996 to 2015. Cox regression with antiepileptic medication use as a time-dependent variable was used to analyze PCa risk overall, and low, medium and high-risk PCa separately. The analysis was adjusted for age, screening trial arm, and other drugs in use, including statins, antidiabetic drugs, antihypertensive drugs, aspirin, and nonsteroidal anti-inflammatory drugs. Compared to the nonusers of AEDs, overall PCa risk was decreased among AED users (hazard ratio [HR] = 0.86, 95% confidence interval [CI] = 0.76-0.96). A similar PCa risk decrease was observed among users of HDACi AEDs (HR = 0.87, 95% CI = 0.76-1.01), but no risk difference was found when comparing HDACi AED users to users of other AEDs (HR = 0.98, 95% CI = 0.76-1.27). Our study showed a decrease in overall PCa risk among men using AEDs compared to nonusers. The risk associations were similar for HDAC inhibitors as for AEDs in general.

INTRODUCTION: Newborn infants with transposition of the great arteries (d-TGA) need immediate care for an optimal outcome. This study comprised a nationwide 11-year population-based cohort of d-TGA infants, and assessed whether the implementation of a nationwide systematic fetal screening program, or other perinatal, or perioperative factors, are associated with mortality or an increased need for hospital care. MATERIAL AND METHODS: The national cohort consisted of all live-born infants with simple d-TGA (TGA ± small ventricular septal defect, n = 127) born in Finland during 2004-2014. Data were collected from six national registries. Prenatal diagnosis and perinatal and perioperative factors associated with mortality and length of hospitalization were evaluated. RESULTS: Preoperative mortality was 7.9%, and the total mortality was 8.7%. The prenatal detection rate increased after introducing systematic fetal anomaly screening from 5.0% to 37.7% during the study period (P < .0001), but the total mortality rate remained unchanged. All prenatally diagnosed infants (n = 27) survived. Lower gestational age (odds ratio 0.68, P = .012) and higher maternal age at birth (odds ratio 1.16, P = .036) were associated with increased mortality in multivariable analysis. Older infant age at time of operation (P = .002), longer aortic clamp time (P < .001), and higher maternal body mass index (P = .027) were associated with longer initial hospital stay. An extended need for hospital care during the first year of life was multi-factorial. CONCLUSIONS: In our cohort, none of the prenatally diagnosed d-TGA infants died. As a result of the limited prenatal detection rates, however, the sample size was insufficient to reach statistical significance. The d-TGA infants born with lower gestational age and to older mothers had increased mortality.

INTRODUCTION: Several surgical techniques are available for pediatric esophageal reconstruction. We started to use pedicled jejunum interposition graft (PJIG) because other techniques had significant long-term complications. In this retrospective study, the indications, surgical complications, and long-term outcomes were assessed in patients with PJIG. MATERIALS AND METHODS: With ethical consent, we reviewed the hospital records of 14 patients (7 females) who from 2005 to 2019 underwent a total of 16 esophageal reconstructions with PJIG. RESULTS: Median age at PJIG was 1.6 (range: 0.2-15) years. Underlying conditions were esophageal atresia (EA) (n = 11) or native esophagus lost by trauma or infection (n = 3). Eight patients with EA underwent PJIG as primary reconstruction and three as a rescue operation after complications in primary repair. Significant surgical complications occurred in 43% of patients. Major reoperations in six (43%) patients included resection and reanastomosis of strictured proximal PJIG (n = 1) and redo PJIG after failure of the first operation (n = 2). Surgical mortality was nil. After a median follow-up of 6.5 (range: 0.7-14) years, 13 (93%) patients survived, and 1 died of congenital heart disease. PJIG failed in three (23%) survivors of whom two underwent graft removal because of life-threatening aspiration and one did not start oral feeds at all. Ten survivors (77%) have full enteral feeds. Respiratory function in the survivors is satisfactory. Two patients have moderate and three mild gastroesophageal reflux symptoms. CONCLUSION: PJIG was a functional option for a variety of conditions that required esophageal reconstruction. However, significant early and late complications required major surgical revisions.

BACKGROUND The appearance of human leukocyte antigen (HLA) antibodies after solid organ transplantation predisposes recipients to graft dysfunction. In theory, vascular homografts, which are widely used in children with congenital heart defects, may cause allosensitization. MATERIAL AND METHODS In this single-center retrospective study, the presence of pre-existing HLA antibodies in pediatric heart transplant (HTx) recipients with a vascular homograft was evaluated in a cohort of 12 patients. HLA antibodies were screened before and after HTx and positive screening results were confirmed and identified using the Luminex® single antigen bead method. Endomyocardial biopsies (EMB) and coronary angiography studies were re-evaluated to assess the prevalence of acute rejections and coronary artery change in these patients. RESULTS At the time of HTx, 8 patients (67%) had HLA antibodies detected by the Luminex assay, none of which were heart donor specific (DSA). All patients had negative leukocyte crossmatch. One patient developed DSAs against homograft donor prior to HTx. After the HTx, 5 patients (42%) developed DSAs against the heart donor and 4 patients (40%) against the homograft donor. In 2 patients (17%), the antibodies were against both heart and homograft donors. The rejection rate or prevalence of coronary artery vasculopathy did not differ significantly between the homograft cohort and our historical controls. CONCLUSIONS Our results suggest that the prevalence of DSAs against homograft donor prior to HTx is relatively rare. However, almost half of the patients developed DSAs against homograft post-HTx. The clinical importance of these antibodies warrants further studies.

BACKGROUND: We evaluated whether the administration of sildenafil in children undergoing the TCPC operation shortened the interval from the operation to the removal of the pleural and peritoneal drains. METHODS: We retrospectively reviewed the data of 122 patients who had undergone the TCPC operation between 2004 and 2014. Patients were divided into two groups on the basis of their treatments. Sildenafil was orally administered pre-operatively in the morning of the procedure or within 24 hours after the TCPC operation to the sildenafil group (n = 48), which was compared to a control group (n = 60). Fourteen patients were excluded from the study. RESULTS: The primary outcome measure was the time from the operation to the removal of the drains. The study groups had similar demographics. The median [interquartile range] time for the removal of drains (sildenafil group 11 [8-19] vs control group 11 [7-16] d, P = .532) was comparable between the groups. The median [interquartile range] fluid balance on the first post-operative day was significantly higher (P = .001) in the sildenafil group compared with controls (47 [12-103] vs 7 [-6-67] mL kg-1 ). The first post-operative day fluid balance was a significant predictor for a prolonged need for drains in the multivariate analysis. CONCLUSIONS: Sildenafil administration, pre-operatively or within 24 hours after the TCPC operation, did not reduce the required time for pleural and peritoneal drains but was associated with a significantly higher positive fluid balance.

OBJECTIVES: We sought to describe early and late outcomes in a large surgical series of patients with anomalous aortic origin of coronary arteries. METHODS: We performed a retrospective multicentre study including surgical patients with anomalous aortic origin of coronary arteries since 1991. Patients with isolated high coronary takeoff and associated major congenital heart disease were excluded. RESULTS: We collected 156 surgical patients (median age 39.5 years, interquartile range 15-53) affected by anomalous right (67.9%), anomalous left (22.4%) and other anatomical abnormalities (9.6%). An interarterial course occurred in 86.5%, an intramural course in 62.8% and symptoms in 85.9%. The operations included coronary unroofing (56.4%), reimplantation (19.2%), coronary bypass graft (15.4%) and other (9.0%). Two patients with preoperative cardiac failure died postoperatively (1.3%). All survivors were discharged home in good clinical condition. At a median follow-up of 2 years (interquartile range 1-5, 88.5% complete), there were 3 deaths (2.2%), 9 reinterventions in 8 patients (5 interventional, 3 surgical); 91.2% are in New York Heart Association functional class ≤ II, but symptoms persisted in 14.2%; 48.1% of them returned to sport activity. On Kaplan-Meier analysis, event-free survival at follow-up was 74.6%. Morbidity was not significantly different among age classes, anatomical variants and types of surgical procedures. Furthermore, return to sport activity was significantly higher in younger patients who participated in sports preoperatively. CONCLUSIONS: Surgical repair of anomalous aortic origin of coronary arteries is effective and has few complications. Unroofing and coronary reimplantation are safe and are the most common procedures. The occurrence of late adverse events is not negligible, and long-term surveillance is mandatory. Most young athletes can return to an unrestrained lifestyle.

BACKGROUND: Operative mortality after complete atrioventricular septal defect (cAVSD) repair has improved vastly. Less improvement has been demonstrated regarding late mortality and reoperation rates, however. There is evident lack of comprehensive population-based studies analyzing the history and progress of the ever-changing operative results. METHODS: This is a 5-million population-based retrospective study of consecutive 388 cAVSD patients operated in Finland between 1962 and 2014. Data were collected using Children's Cardiac Surgical Registry of Children's Hospital at the Helsinki University Hospital, Finland. Mortality data and reoperation rates were analyzed on a decade-by-decade basis. RESULTS: During the early era, overall mortality was 17.4%, operative mortality constituting 10.9%. The operative results have improved significantly over the decades, and eventually, the last decade showed no mortality. A total of 23 late deaths occurred; of these, 20 were directly heart-related. Half of the late mortality occurred during the first postoperative year. The only significant risk factor for overall mortality was an earlier decade of operation (p < 0.001). Reoperation rates have not decreased but slightly increased over decades (p = 0.621), and reoperations have been performed mainly during the first year after the primary operation. Actuarial freedom from left side atrioventricular valve reoperation at 15 years was 90.9%. CONCLUSIONS: There has been an outstanding improvement in surgical results through the years even though the general operative approach has remained the same. Rates of reoperation have not been declining, but the reoperations are dated to early childhood years. The improvement in results has been ongoing.

BACKGROUND: Anomalous aortic origin of coronary arteries (AAOCA) is a rare abnormality, whose optimal management is still undefined. We describe early outcomes in patients treated with different management strategies. METHODS: This is a retrospective clinical multicenter study including patients with AAOCA, undergoing or not surgical treatment. Patients with isolated high coronary take off and associated major congenital heart disease were excluded. Preoperative, intraoperative, anatomical and postoperative data were retrieved from a common database. RESULTS: Among 217 patients, 156 underwent Surgical repair (median age 39â¯years, IQR: 15-53), while 61 were Medical (median age 15â¯years, IQR: 8-52), in whom AAOCA was incidentally diagnosed during screening or clinical evaluations. Surgical patients were more often symptomatic when compared to medical ones (87.2% vs 44.3%, pâ¯<â¯0.001). Coronary unroofing was the most frequent procedure (56.4%). Operative mortality was 1.3% (2 patients with preoperative severe heart failure). At a median follow up of 18â¯months (range 0.1-23â¯years), 89.9% of survivors are in NYHAâ¯≤â¯II, while only 3 elderly surgical patients died late. Return to sport activity was significantly higher in Surgical patients (48.1% vs 18.2%, pâ¯<â¯0.001). CONCLUSIONS: Surgery for AAOCA is safe and with low morbidity. When compared to Medical patients, who remain on exercise restriction and medical therapy, surgical patients have a benefit in terms of symptoms and return to normal life. Since the long term-risk of sudden cardiac death is still unknown, we currently recommend accurate long term surveillance in all patients with AAOCA.

OBJECTIVES: The aim of the present study was to evaluate procedural risk factors, incidence and timing of reintervention because of recurrent aortic coarctation in children. METHODS: The study cohort consisted of 304 patients with isolated coarctation: 251 underwent surgery and 53 were treated percutaneously (40 balloon angioplasty, 13 stent) at the Helsinki Children's Hospital in 2000-2012. Characteristics, intervention and reintervention data were retrospectively collected from clinical records until 2014 (median follow-up 7.9 years). Age- and sex-matched comparisons between the treatment groups were performed in 86 patients (surgery n = 43, percutaneous n = 43). RESULTS: Forty of the 251 (16%) patients after surgery, 9/40 (23%) patients after balloon angioplasty and 4/13 (31%) patients after stent placement underwent a reintervention after a median time of 3.4, 11.7 and 19.5 months (P < 0.05), respectively. In the surgery group, all reinterventions occurred in children operated on ≤12 months of age and were related to lower body weight and smaller dimensions of the aorta. In the balloon angioplasty group, a higher post-procedure systolic arm-leg blood pressure gradient was associated with reintervention. After stent placement, three-fourths of the reinterventions were performed in a planned postinterventional catheterization. In the age- and sex-matched comparisons (median 5,7 years, range 0,5-17,6), post-procedure blood pressure gradients were higher (mean 10 vs 4 mmHg, P = 0.03), and reinterventions were more common (28%, 95% confidence interval 17-43 vs 2%, 95% confidence interval 0-12) in the percutaneous group compared to the surgery group. CONCLUSIONS: Reinterventions after surgery in neonates were relatively common. In older children, percutaneous treatment carried a higher risk of reinterventions, which were mainly related to residual coarctation after primary treatment.

BACKGROUND: The optimal management and prognostic factors of postsurgical pulmonary vein stenosis remain controversial. We sought to determine current postsurgical pulmonary vein stenosis outcomes and prognostic factors in a multicentric study in the current era. METHODS: Seventy-five patients with postsurgical pulmonary vein stenosis who underwent 103 procedures in 14 European/North American centers (2000-2012) were included retrospectively. A specific pulmonary vein stenosis severity score was developed on the basis of the assessment of each pulmonary vein. End points were death, pulmonary vein reintervention, and restenosis. A univariate and multivariate risk analysis was performed. RESULTS: Some 76% of postsurgical pulmonary vein stenosis occurred after repair of a total anomalous pulmonary venous return. Sutureless repair was used in 42 of 103 procedures (41%), patch veinoplasty was used in 28 procedures (27%), and endarterectomy was used in 16 procedures (16%). Overall pulmonary vein restenosis, reintervention, and mortality occurred in 56% (n = 58/103), 49% (n = 50/103), and 27% (n = 20/75), respectively. Sutureless repair was associated with less restenosis (40% vs 67%; P = .007) and less reintervention (31% vs 61%; P = .003). Mortality after sutureless repair (20%; 7/35) tends to be lower than after nonsutureless repair (33%; 13/40) (P = .22). A high postoperative residual pulmonary vein stenosis score at the time of hospital discharge was an independent risk factor for restenosis (hazard ratio [HR], 1.55; P < 10-4), reintervention (HR, 1.33; P < 10-4), and mortality (HR, 1.37; P < 10-4). The sutureless technique was an independent protective factor against restenosis (HR, 0.27; P = .006). CONCLUSIONS: Postsurgical pulmonary vein stenosis still has a guarded prognosis in the current era. The sutureless technique is an independent protective factor against restenosis. The severity of the residual disease evaluated by a new severity score is an independent risk factor for poor outcomes regardless of surgical technique.

BACKGROUND: We sought to report the frequency, types, and outcomes of left-sided reoperations (LSRs) after an arterial switch operation (ASO) for patients with D-transposition of the great arteries (D-TGA) and double-outlet right ventricle (DORV) TGA-type. METHODS: Seventeen centers belonging to the European Congenital Heart Surgeons Association (ECHSA) contributed to data collection. We included 111 patients who underwent LSRs after 7,951 ASOs (1.4%) between January 1975 and December 2010. Original diagnoses included D-TGA (n = 99) and DORV TGA-type (n = 12). Main indications for LSR were neoaortic valve insufficiency (n = 52 [47%]) and coronary artery problems (CAPs) (n = 21 [19%]). RESULTS: Median age at reoperation was 8.2 years (interquartile range [IQR], 2.9-14 years). Seven patients died early after LSRs (6.3%); 4 patients with D-TGA (5.9%) and 3 patients with DORV TGA-type (25%) (p = 0.02). Median age at last follow-up was 16.1 years (IQR, 9.9-21.8 years). Seventeen patients (16%) required another reoperation, which was more frequent in patients with DORV- TGA type (4 of 9 [45%]) than in patients with D-TGA (13 of 95 [14%]). Late death occurred in 4 patients (4 of 104 [3.8%]). The majority of survivors were asymptomatic at last clinical examination (84 of 100 [84%]). CONCLUSIONS: Reoperations for residual LSRs are infrequent but may become necessary late after an ASO, predominantly for neoaortic valve insufficiency and CAPs. Risk at reoperation is not negligible, and DORV TGA-type anatomy, as well as procedures on the coronary arteries, were significantly associated with a higher morbidity and a lower overall survival. Recurrent reoperations after LSRs may be required.

BACKGROUND: Primary pulmonary vein stenosis (PPVS) still carries a poor prognosis, and prognostic factors remain controversial. The aim of this study was to determine outcomes and prognostic factors after PPVS repair in the current era. METHODS: Thirty patients with PPVS and a normal pulmonary vein (PV) connection operated on in 10 European/North American centers (2000-2012) were included retrospectively. A specific PVS severity score was developed based on the assessment of each PV. Studied end points were death, PV reoperation, and restenosis. A univariate and multivariate risk analysis was performed. RESULTS: The mean number of affected PVs per patient was 2.7 ± 1.1. Sutureless repair was used in 21 patients (70%), endovenectomy was used in 5 patients, and patch venoplasty was used in 4 patients. Overall PV restenosis, reoperation, and mortality occurred in 50%, 40%, and 30% of patients respectively. Freedom from mortality, reoperation, and restenosis at 8 years of follow-up was 70% ± 8%, 62% ± 8%, and 47% ± 9%, respectively. Restenosis and mortality rates after sutureless repair versus nonsutureless repair were 57% (n = 12 of 21) versus 33% (n = 3 of 9) (p = 0.42) for restenosis and 38% (n = 8 of 21) versus 11% (n = 1 of 9) (p = 0.21) for mortality. Patients selected for a sutureless technique were younger and smaller and had more severe disease before operation. A postoperative high PVS score and pulmonary hypertension 1 month after the operation were independent risk factors for restenosis (hazard ratio [HR], 1.34; p = 0.002 and HR, 6.81; p = 0.02, respectively), reoperation (HR, 1.24; p = 0.01 and HR, 7.60; p = 0.02), and mortality (HR, 1.39; p = 0.01 and HR, 39.5; p = 0.008). CONCLUSIONS: Primary PVS still has a guarded prognosis in the current era despite adoption of the sutureless technique. Postoperative pulmonary hypertension and severity of disease evaluated by a new severity score are independent prognostic factors regardless of surgical technique.

OBJECTIVES: We investigated the impact of initial shunt type, a Blalock-Taussig (BT) shunt versus a right ventricle to pulmonary artery conduit (RV-PA) on myocardial function at different stages of surgical palliation in patients with hypoplastic left heart syndrome (HLHS). METHODS: A population-based cohort of 63 Finnish children with HLHS (BT n = 23, RV-PA n = 40) born between 2003 and 2010 were studied retrospectively by echocardiography prior to Stages 1, 2 and 3 palliation and 0.5-3 years after Stage 3. For comparison of systolic myocardial function, we evaluated the RV fractional area change (FAC), strain, strain rate and mechanical synchrony from the apical 4-chamber view by velocity vector imaging. RESULTS: There were no intergroup differences in demographics during the study period. At baseline, no intergroup differences were detected in RV systolic myocardial function. Before Stage 2, RV FAC was higher ( P = 0.03) in the RV-PA conduit group. At Stage 3, an increase in all systolic myocardial functional parameters was observed in the BT shunt group. After Stage 3, the BT shunt group had better RV systolic function. In multiple regression analysis, the shunt type and the stage of palliation had an impact on myocardial function. CONCLUSIONS: Although patients with HLHS initially palliated with a BT shunt demonstrate lower RV FAC after Stage I, RV FAC improves after Stage 2 with better systolic performance after Stage 3 compared with those initially palliated with an RV-PA conduit.

BACKGROUND: Corticosteroids can improve the hemodynamic status of neonates with postoperative low cardiac output syndrome after cardiac operations. This study compared a prophylactically administered stress-dose corticosteroid (SDC) regimen against placebo on inflammation, adrenocortical function, and hemodynamic outcome. METHODS: Forty neonates undergoing elective open heart operations were randomized into two groups. The SDC group received perioperatively 2 mg/kg methylprednisolone, and 6 hours after the operation, a hydrocortisone infusion (0.2 mg/kg/h) was started with tapering doses for 5 days. Placebo was administered in a similar fashion. An adrenocorticotropic hormone stimulation test was performed after the therapy. The primary endpoint of the study was plasma concentration of interleukin (IL-6). Secondary clinical outcomes included plasma cortisol, IL-10, C-reactive protein, echocardiographic systemic ventricle contractility evaluated by the Velocity Vector Imaging program, the inotropic score, and time of delayed sternal closure. RESULTS: The IL-6 values of the SDC group were significantly lower postoperatively than in the placebo group. Significantly lower inotropic scores (p < 0.05), earlier sternal closure (p = 0.03), and less deterioration in the systemic ventricle mean delta strain values between the preoperative and the first postoperative assessment (p = 0.01) were detected for the SDC group. The SDC therapy did not suppress the hypothalamic-pituitary-adrenal axis more than placebo. The mean plasma cortisol level did not decline in the placebo group after the operation. CONCLUSIONS: The SDC regimen for 5 days postoperatively in neonates was safe and did not cause suppression of the hypothalamic-pituitary-adrenal axis. Furthermore, the open heart operation per se did not lead to adrenal insufficiency in neonates.

BACKGROUND: Postoperative pain after median sternotomy is usually treated with i.v. opioids. We hypothesized that continuous wound infusion of ropivacaine decreases postoperative morphine consumption and improves analgesia in children who undergo cardiac surgery. METHODS: This randomized, double-blind study comprised 49 children aged 1-9 years who underwent atrial septal defect (ASD) closure. Patients received continuous local anesthetic wound infiltration either with 0.2% ropivacaine, 0.3-0.4 mg·kg(-1) ·h(-1) (Group R) or with saline (Group C). Rescue morphine consumption, Objective Pain Scale (OPS), time to mobilization, time to enteral food intake, and time to discharge were recorded. RESULTS: There were no statistically significant differences in morphine consumption at 24, 48, and 72 h postsurgery between R and C groups. There was a weak evidence for a difference in the time to the first morphine administration after tracheal extubation to be longer for Group R than Group C (186.2 vs 81.0 min; 95% CI (-236.5, 26.2), P = 0.114). The incidence of nausea and vomiting were comparable between the groups. No signs or symptoms of local anesthetic toxicity were registered. CONCLUSIONS: Contrary to our hypothesis, continuous ropivacaine wound infusion did not reduce morphine consumption, pain score values, or nausea and vomiting in children who underwent ASD closure with median sternotomy and mediastinal drain.
