Abstract
BACKGROUND Surgical management of congenital heart disease (CHD) has increased worldwide, but healthcare-associated infections (HAI) can impede these efforts. This study analysed the incidence of HAI, the impact of preventive interventions, and microbiological profiles in a paediatric cardiovascular surgery program. METHODS Cohort study including children under 12 years of age with CHD who underwent cardiovascular surgery between 2010-2021 in Medellín, Colombia (a middle-income setting). Data were collected from medical and laboratory records and infection control program databases. Impact of various preventive interventions was assessed using a Poisson model. A p-value less than 0.05 was considered statistically significant. RESULTS 2512 surgeries were analysed. Incidence of surgical site infection (SSI) was 5.9%, followed by central line-associated bloodstream infection (CLABSI; 4.7%), catheter-associated urinary tract infection (CAUTI; 2.2%) and ventilator-associated pneumonia (VAP; 1.4%). Most of the strategies focused on preventing SSI, resulting in a reduction from 9.5% in 2010 to 3.0% in 2021 (p=0.030). Antibiotic prophylaxis based on patient weight and continuous infusion had an impact on reducing SSI (RR:0.56; 95%CI:0.32-0.99). Vacuum-assisted closure (VAC) in clean wounds reduced 100% infections. No significant risk reduction was observed for other HAI with the implemented interventions. CONCLUSION Preventive strategies effectively reduced SSI but no other infections, emphasizing the need for targeted approaches to address a broader spectrum of HAI successfully.

Open Chest Duration Following Congenital Cardiac Surgery Increases Risk for Surgical Site Infection. Pediatr Cardiol 2022:10.1007/s00246-022-03088-4. [PMID: 36583758 DOI: 10.1007/s00246-022-03088-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 12/21/2022] [Indexed: 12/31/2022]
Abstract
Surgical site infections (SSI) following congenital heart surgery (CHS) remain a significant source of morbidity. Delayed sternal closure (DSC) is often required to minimize the potential for hemodynamic instability. The purpose of this study was to determine the incidence of SSI among patients undergoing DSC versus primary chest closure (PCC) and to define a potential inflection point for increased risk of SSI as a function of open chest duration (OCD).A retrospective review of our institutional Society of Thoracic Surgeons dataset is to identify patients undergoing CHS at our institution between 2015 and 2020. Incidences of SSI were compared between DSC and PCC patients. DSC patients were evaluated to determine the association of OCD and the incidence of SSI.2582 operations were performed at our institution between 2015 and 2020, including 195 DSC and 2387 PCC cases. The incidence of SSI within the cohort was 1.8% (47/2,582). DSC patients had significantly higher incidences of SSI (17/195, 8.7%) than PCC patients (30/2387, 1.3%, p < 0.001). Further, patients with an OCD of four or more days had a significantly higher incidence of SSI (11/62, 17.7%, p = 0.006) than patients with an OCD less than 4 days (6/115, 5.3%).The incidence of SSI following CHS is higher in DSC patients compared to PCC patients. Prolonged OCD of 4 days or more significantly increases the risk of SSI and represents a potentially modifiable risk factor for SSI predisposition. These data support dedicated, daily post-operative assessment of candidacy for chest closure to minimize the risk of SSI.

The Future of Cardiothoracic Surgical Critical Care Medicine as a Medical Science: A Call to Action. MEDICINA (KAUNAS, LITHUANIA) 2022; 59:47. [PMID: 36676669 PMCID: PMC9867461 DOI: 10.3390/medicina59010047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 12/28/2022]
Abstract
Cardiothoracic surgical critical care medicine (CT-CCM) is a medical discipline centered on the perioperative care of diverse groups of patients. With an aging demographic and an increase in burden of chronic diseases the utilization of cardiothoracic surgical critical care units is likely to escalate in the coming decades. Given these projections, it is important to assess the state of cardiothoracic surgical intensive care, to develop goals and objectives for the future, and to identify knowledge gaps in need of scientific inquiry. This two-part review concentrates on CT-CCM as its own subspeciality of critical care and cardiothoracic surgery and provides aspirational goals for its practitioners and scientists. In part one, a list of guiding principles and a call-to-action agenda geared towards growth and promotion of CT-CCM are offered. In part two, an evaluation of selected scientific data is performed, identifying gaps in CT-CCM knowledge, and recommending direction to future scientific endeavors.

Abstract
Purpose The clinical outcomes of delayed chest closure (DCC) compared with primary chest closure (PCC) following lung transplantation, including perioperative outcomes and long-term survival, remained controversial. This was the first systematic review and meta-analysis aimed to identify the short- and long-term outcomes of DCC following lung transplantation. Methods We comprehensively searched electronic literature from 4 databases up to April 1st, 2022. Dichotomous data and continuous data were pooled with odds ratio and weighted mean difference, respectively. The quality of included studies was assessed with the Newcastle–Ottawa Scale. Results Ten studies were included in the systematic review and 4 studies were included in the meta-analysis. Pooled analysis showed that DCC was associated with an increased risk of surgical site infection, prolonged hospital stays, and higher risk of primary graft dysfunction compared to PCC. The 30 day and 5 year survival were higher in PCC cohort compared with DCC cohort while differences in survival at 6 months was insignificant. Conclusion Our findings do not support the aggressive application of DCC. DCC should be cautiously applied since its association with worse perioperative outcomes and higher mortality. But it remains the life-saving steps under dangerous circumstances.

Abstract
Surgical site infections (SSIs) represent a potential complication of surgical procedures, with a significant impact on mortality, morbidity, and healthcare costs. Patients undergoing cardiac surgery and thoracic surgery are often considered patients at high risk of developing SSIs. This consensus document aims to provide information on the management of peri-operative antibiotic prophylaxis for the pediatric and neonatal population undergoing cardiac and non-cardiac thoracic surgery. The following scenarios were considered: (1) cardiac surgery for the correction of congenital heart disease and/or valve surgery; (2) cardiac catheterization without the placement of prosthetic material; (3) cardiac catheterization with the placement of prosthetic material; (4) implantable cardiac defibrillator or epicardial pacemaker placement; (5) patients undergoing ExtraCorporal Membrane Oxygenation; (6) cardiac tumors and heart transplantation; (7) non-cardiac thoracic surgery with thoracotomy; (8) non-cardiac thoracic surgery using video-assisted thoracoscopy; (9) elective chest drain placement in the pediatric patient; (10) elective chest drain placement in the newborn; (11) thoracic drain placement in the trauma setting. This consensus provides clear and shared indications, representing the most complete and up-to-date collection of practice recommendations in pediatric cardiac and thoracic surgery, in order to guide physicians in the management of the patient, standardizing approaches and avoiding the abuse and misuse of antibiotics.

Abstract
Abstract
Background Delayed sternal closure (DSC) is being increasingly used as an interim support to help the dysfunctional heart in the road to recovery after complex pediatric cardiac surgeries. The purpose of this study was to assess the conduct of DSC at a tertiary care center.
Methods Between 2018 and 2019, 185 consecutive pediatric patients (below 12 years of age) underwent cardiac surgery at a tertiary care center. The incidence and causes of DSC were noted. The various pre, intra and postoperative factors till discharge or demise were noted and analyzed.
Results In this study, DSC was done in 63 patients (34.05%) with a median age and weight of 29 days (18–100 days) and 4 kg (2–12.3 kg), respectively. Transposition of great arteries (TGA) (41.27%) constituted the majority, followed by total anomalous pulmonary venous connection (TAPVC) (26.98%). Myocardial edema (49.21%) was the most common indication for DSC. Mean duration of open chest was 40.75 ± 18.58 hours. All-cause mortality was 19.05% (12/63). On multivariate analysis by logistic regression, the independent predictors of mortality were needed for preoperative mechanical ventilation (OR 42.82, 95% CI = 4.52–406.03, p < 0.001) and development of postoperative sepsis (OR 20.07, 95% CI = 2.12–189.80, p = 0.002).
Conclusions DSC is a safe and effective technique in the management of complex pediatric cardiac surgeries. It provides assistance to the severely dysfunctional myocardium soon after the surgery and helps in stabilization of hemodynamics with avoidance of postoperative mediastinal compression. Early sternal closure should be considered on the basis of cardiovascular function and/or resolution of primary indication for DSC.

Abstract
Sternal wound infections (SWI) in delayed sternal closure (DSC) patients are a healthcare burden after congenital heart surgery. There are no guidelines specific for pediatric DSC patients to prevent this costly complication. The hypothesis was that the modifications to a bundled approach for DSC patients would decrease the SWI rate. For this prospective cohort study, DSC patients were postoperatively admitted to a pediatric cardiac care unit from February 2017 to January 2018. Using a modified protocol for prevention of SWI, the infection rates pre- and post-modified protocol were compared. The primary outcome measure was SWI. Secondary outcome measures were compliance with modifications. Retrospective review of cases in pre-protocol modification era from January 1, 2014 to December 31, 2016 showed 377 pediatric cardiopulmonary bypass cases and 39 (10.4%) underwent DSC. During the post-protocol modification era, there were 129 cardiopulmonary bypass cases and 17 (13%) DSC cases. The SWI rate in DSC were 7.7% and 0% for pre-intervention and post-intervention, respectively (p = 0.52). The Bayesian confidence interval with Jeffreys prior gives a 95% confidence interval of 1.5% to 18.3% for pre-intervention and 0 to 13.5% for post-intervention. Compliance with the protocol bundle during the post protocol era was 93-100%. Although preliminary results are not statistically significant due to cohort size, the economic burden and increased LOS for each SWI is clinically significant. The early results of reduced infections for DSC patients using a modified bundle approach appear promising. Continued study and a multicenter project would be beneficial.

Characterization of Postoperative Infection Risk in Cardiac Surgery Patients With Delayed Sternal Closure. J Cardiothorac Vasc Anesth 2020; 34:1238-1243. [PMID: 32127277 DOI: 10.1053/j.jvca.2020.01.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2019] [Revised: 01/07/2020] [Accepted: 01/08/2020] [Indexed: 11/11/2022]
Abstract
OBJECTIVES To compare the incidence of postoperative infection in cardiac surgery patients who had delayed sternal closure (DSC) with those who had primary sternal closure (PSC) and evaluate the effectiveness of antibiotic prophylaxis in DSC patients. DESIGN Retrospective, observational cohort study with propensity score matching. SETTING Single academic medical center. PARTICIPANTS Cardiothoracic surgery patients, excluding transplantation patients, from a single academic medical center who had DSC or PSC between November 2015 and November 2018. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of 2,685 patients who had cardiac surgery with cardiopulmonary bypass, 99 had DSC. Fifty-nine DSC patients met study inclusion criteria, and the final propensity score matched cohort included 57 patients with DSC and 57 patients with PSC. Propensity score matching reduced bias but was unable to balance all covariates. The most common indication for DSC was coagulopathy in 32 of the 57 patients. All patients in the PSC group received routine antibiotic prophylaxis for 48 hours after surgery. Patients in the DSC group received prolonged broadened prophylaxis until 48 hours after sternal closure. Despite prolonged broadened antibiotic prophylaxis, the DSC group had a higher rate of postoperative infection (31.6% v 3.5%; p < 0.005), mainly pneumonia (19.3% v 1.8%; p < 0.005), in the first 30 days after surgery. There was no difference in the incidence of sepsis (5.3% v 0%; p = 0.24), superficial skin and soft tissue infection (1.8% v 1.8%; p = 1), or mediastinitis/deep tissue infection (5.3% v 0%; p = 0.24) in patients with DSC. Seventy-seven percent of causative organisms for infection were Gram-negative bacteria in the matched cohort. CONCLUSION The incidence of postoperative infection, particularly pneumonia, is high in cardiothoracic surgery patients with DSC, even with prolonged broadened antibiotic prophylaxis, but the rate of mediastinitis/deep tissue infection did not appear to be greater with DSC. Additional research is needed into optimal antibiotic prophylaxis in this high-risk group of patients.
