Preventing deep wound infection after coronary artery bypass grafting: a review
Texas Heart Institute journal / from the Texas Heart Institute of St. Luke's Episcopal Hospital, Texas Children's Hospital, 2013
The consequences of deep wound infections before, during, and after coronary artery bypass grafting have prompted research to clarify risk factors and explore preventive measures to keep infection rates at an irreducible minimum. An analysis of 42 studies in which investigators used multivariate logistic regression analysis revealed that diabetes mellitus and obesity are by far the chief preoperative risk factors. A 4-point preoperative scoring system based on a patient's body mass index and the presence or absence of diabetes is one practical way to determine the risk of mediastinitis, and other risk-estimate methods are being refined. Intraoperative risk factors include prolonged perfusion time, the use of one or more internal mammary arteries as grafts, blood transfusion, and mechanical circulatory assistance. The chief postoperative risk factor is reoperation, usually for bleeding. Unresolved issues include the optimal approach to Staphylococcus aureus nasal colonization and...

Objective: To determine the incidence and predictor of postoperative wound infection in patients underwent coronary artery bypass grafting (CPB). Methods: This was a prospective comparative study of 577 patients who underwent cardiac surgery with (CPB) was conducted at cardiac surgery department of Punjab Institute of cardiology, Lahore from 1st March 2012 to 31st March 2017. Consecutive patients undergoing elective and isolated CABG, both genders age ≥20 years, with normal ejection fraction were included in the study Results: Out of 577 patients of which 166(87.83%) were male while 23(12.16%) were female. The mean age of the patient was 53.23 ± 8.43. Incidence of post-operative wound infection in patients underwent coronary artery bypass grafting (CPB) was 73(12.65%). Common co morbid conditions were hypertension 50%, diabetes mellitus (43.5%), smoking (31.1%), hyperlipidemia (20.3%), prior of stoke (12.2%), Prior Surgery (6.8%) and prior renal failure (4.1%), mean CPB time (61.69 ± 32.27), ICU stay 976.03 ± 31.93), mean Cross clamp time(25.27 ± 19.17mg/dl) and Hospital stay (10.16 ± 5.6 day) were more in WI group. Themortality was found to be high in WI group (23.3%). Logistic regression showed that significantly predicted of the post-operative WI were elder age,diabetes mellitus, smoking, family history of IHD, hyperlipidemia, cardiopulmonary bypass time, ICU stay, hospital stay. Conclusion: We can conclude that wound infected patients are at significantly greater risk of incidence, morbidity and mortality after cardiac surgery.

Objective: To evaluate the prevalence of leg complications following leg-vein harvest for coronary artery bypass grafting. Method: A questionnaire was sent to patients who had coronary artery bypass surgery between January 1993 and December 1998. Questions addressed pain, numbness, infection, swelling and general healing. The relationship between the risk factors of diabetes, peripheral vascular disease, previous fractures/injuries to legs, previous deep vein clots and arthritis affecting the legs with post operative symptoms of pain, numbness, swelling and general healing was explored with multivariate analysis. Results: Of 700 questionnaires sent out 497 were returned, of which 422 (60%) were suitable for analysis. Numbness or tingling related to the wound was reported by 256 (61%), of whom 94 (37%) improved within 3 months. However, 105 (41%) had persistent numbness beyond 2 years. Pain in the wound was reported by 193 (46%), of whom 149 (77%) reported that this had improved by 3 months and only 19 (10%) had pain persisting beyond 2 years. A leg wound infection was reported by 126 (32%) patients, with 82 (65%) of these receiving antibiotics. A total of 336 (87% of 387 responses) described their wound as completely healed at 3 months. Unilateral leg swelling was reported by 175 (41%) with 98 of these (56% of those with swelling) improving by 3 months and 41 (23%) with swelling persisting beyond 2 years. There was no relation of wound problems to examined risk factors diabetes (P-values for numbness 0.31, wound healing 0.15, swelling 0.21, pain 0.22) and peripheral vascular disease (P-values for numbness 0.8, wound healing 0.21, swelling 0.18, pain 0.09). There was insufficient data to comment on the influence of fractures/injuries to legs, previous deep vein clots and arthritis affecting the legs. Conclusions: Wound complications are common following leg vein harvest. Prevalence of infection was higher than has previously been reported. Few people suffer long-term pain from saphenous nerve damage although paraesthesia and swelling were common long-term complications. We did not identify either diabetes or peripheral vascular disease as a risk factor for pain, numbness, swelling or problems with general healing. There is a need for a large multicentre prospective study. q

Background: Infection of leg wounds is a common complication following great saphenous vein harvesting (GSV) for coronary bypass grafting (CABG). This complication can result in increased risk of patient morbidity and mortality by causing septicemia, and gangrene, subjecting the patients to amputation. This study aimed to assess the efficacy of negative pressure wound therapy (NPWT) compared to conventional wound care in infected leg wounds following GSV harvesting for myocardial revascularization. Results: The NPWT group had a significantly lower rate of deep vein thrombosis (p = 0.013), osteomyelitis (p < 0.001), bed sores (p < 0.001), shorter duration of tissue edema (p < 0.001), and lesser discharge (p < 0.001). Also, the length of hospital stay was significantly shorter in the NPWT group (p < 0.001). Multivariable analysis revealed that traditional wound care (without NPWT, p < 0.001) and wound stage IV (p = 0.001) significantly and independently prolonged the length of hospital stay. Conclusions: The use of NPWT in advanced complicated infected leg wounds could improve patients' outcomes and satisfaction by decreasing the rate of complications and the length of hospital stay.

BACKGROUND-Packed RBC transfusion has been postulated to increase morbidity and mortality after cardiac/general surgical operations, but its effects after lower extremity bypass (LEB) have not been studied extensively. STUDY DESIGN-Using the Vascular Study Group of New England's database (2003-2010), we examined 1,880 consecutive infrainguinal LEB performed for critical limb ischemia. Perioperative transfusion was categorized as 0 U, 1 to 2 U, and ≥3 U. Cohort frequency group matching was used to compare groups of patients receiving 1 to 2 U and 0 U with patients receiving ≥3 U using age, coronary artery disease, diabetes, urgency, and indication of revascularization. Primary end points were perioperative mortality, wound infection, and loss of primary graft patency at discharge, as well as 1-year mortality and loss of primary graft patency. RESULTS-In the study cohort, 1,532 LEBs (81.5%) received 0 U, 248 LEBs (13.2%) received 1 to 2 U, and 100 LEBs (5.3%) received ≥3 U transfusion. In the study cohort and group frequency matched cohort, transfusion was associated with significantly higher perioperative wound infection (0 U:4.8% vs 1 to 2 U: 6.5% vs ≥3 U: 14.0%; p = 0.0004) and graft thrombosis at discharge (4.5% vs 7.7% vs 15.3%; p < 0.0001). At 1 year, there were no differences in infection or graft patency. In multivariate analysis, transfusion was independently associated with increased perioperative wound infection in the study cohort and group frequency matched cohort (1 to 2 U
Serious wound infections after minimally invasive coronary bypass procedures
The Annals of Thoracic Surgery, 1998
Background. Minimally invasive coronary artery bypass grafting has become an increasingly accepted therapy for selected patients with single-vessel coronary artery disease. Reported morbidity has focused on anastomotic problems, but the occurrence of serious wound complications after these procedures has not been well documented.
A fifteen-year wound surveillance study after coronary artery bypass
Annals of Thoracic Surgery, 1993
Wound infections after coronary artery bypass operations have been continuously monitored at the Minneapolis Veterans Affairs Hospital for 15 years. All patients were followed up for 30 days. From 1977 to 1991, 2,402 coronary artery bypass operations were performed, and wound infections developed in 125 (5%) patients. There were 71 (3%) chest infections of which 33 (1.4%) were major and 38 (1.6%) superficial. Greater than 94% of these grew only a single organism, of which 74% were StuphyZococcus species. There were 63 (2.6%) leg wound infections. More than 50% of these grew multiple organisms, of which 68% were enteric in origin. Nine (0.4%) patients had simultaneous chest and leg infections.

To analyze patient risk factors and processes of care associated with secondary surgical-site infection (SSI) after coronary artery bypass grafting (CABG). Data were collected prospectively between February and October 2010 for consenting adult patients undergoing CABG with saphenous vein graft (SVG) conduits. Patients who developed a deep or superficial SSI of the leg or groin within 65 days of CABG were compared with those who did not develop a secondary SSI. Among 2174 patients identified, 65 (3.0%) developed a secondary SSI. Median time to diagnosis was 16 days (interquartile range 11-29) with the majority (86%) diagnosed after discharge. Gram-positive bacteria were most common. Readmission was more common in patients with a secondary SSI (34% vs 17%, P < .01). After adjustment, an open SVG harvest approach was associated with an increased risk of secondary SSI (adjusted hazard ratio [HR], 2.12; 95% confidence interval [CI], 1.28-3.48). Increased body mass index (adjusted HR,...
