RESUMEN
Diabetes and hyperglycemic events in cardiac surgical patients are associated with postoperative morbidity and mortality. The causes of dysglycemia, the abnormal fluctuations in blood glucose concentrations, in the perioperative period include surgical stress, surgical techniques, medications administered perioperatively, and patient factors. Both hyperglycemia and hypoglycemia lead to poor outcomes after cardiac surgery. While trying to control blood glucose concentration tightly for better postoperative outcomes, hypoglycemia is the main adverse event. Currently, there is no definite consensus on the optimum perioperative blood glucose concentration to be maintained in cardiac surgical patients. This review provides an overview of perioperative glucose homeostasis, the pathophysiology of dysglycemia, factors that affect glycemic control in cardiac surgery, and current practices for glycemic control in cardiac surgery.

INTRODUCTION: Deep sternal wound infection (DSWI) is a rare complication associated with high mortality. Seasonal variability in surgical site infections has been demonstrated, however, these patterns have not been applied to DSWI. The purpose of this study was to assess temporal clustering of DSWIs. METHODS: All cardiac surgery patients who underwent sternotomy were queried from a regional Society of Thoracic Surgeons database from 17 centers from 2001 to 2019. All patients with the diagnosis of DSWI were then identified. Cluster analysis was performed at varying time intervals (monthly, quarterly, and yearly) at the hospital and regional level. DSWI rates were calculated by year and month, and compared using mixed-effects negative binomial regression. RESULTS: A total of 134,959 patients underwent a sternotomy for cardiac surgery, of whom 469 (0.35%) developed a DSWI. Rates of DSWI per hospital across all years ranged from 0.12% to 0.69%. Collaborative-level rates of DSWIs were the greatest in September (0.44%) and the lowest in January (0.30%). Temporal clustering was not seen across seasonal quarters (high rate in preceeding quarter was not associated with a high rate in the next quarter) (P = 0.39). There were yearly differences across all institutions in the DSWI rates. A downward trend in DSWI rates was seen from 2001 to 2019 (P < 0.001). A difference among hospitals in the cohort was observed (P < 0.001). CONCLUSIONS: DSWI are a rare event within our region. Unlike other surgical site infection, there does not appear to be a seasonal pattern associated with DSWI.

BACKGROUND: We compared postoperative outcomes in octogenarians who underwent off-pump isolated coronary artery bypass grafting for multivessel disease using either skeletonized bilateral or single internal thoracic artery (ITA).MethodsâandâResults: Among 1,532 patients who underwent isolated coronary artery bypass grafting between 2002 and 2021, 173 octogenarians were analyzed retrospectively. After inverse probability of treatment weighting, we found no statistically significant difference regarding patients' preoperative characteristics. No patient experienced deep sternal wound infection. More patients in the single than bilateral ITA group died within 30 days after surgery (5.0% vs. 0%, respectively; P=0.003). The mean follow-up duration was 4.2 years. At 5 years, the freedom from overall death following bilateral versus single ITA grafting was 78.2% and 53.7%, respectively (log-rank test, P=0.003), and freedom from major adverse cardiac and cerebrovascular events (MACCE) was 67.9% and 44.8% respectively (log-rank test, P=0.002). In multivariable Cox models, bilateral ITA grafting was significantly associated with a lower risk of overall death (hazard ratio [HR] 0.555; 95% confidence interval [CI] 0.342-0.903; P=0.018) and MACCE (HR 0.586; 95% CI 0.376-0.913; P=0.018). CONCLUSIONS: Compared with single ITA grafting, off-pump skeletonized bilateral ITA grafting is associated with lower rates of overall death and MACCE in octogenarians undergoing CABG and does not increase the risk of deep sternal wound infection.

INTRODUCTION: Deep sternal wound infection is a rare but feared complication of median thoracotomies and is usually caused by microorganisms from the patient's skin or mucous membranes, the external environment, or iatrogenic procedures. The most common involved pathogens are Staphylococcus aureus, Staphylococcus epidermidis and gram-negative bacteria. We aimed to evaluate the microbiological spectrum of deep sternal wound infections in our institution and to establish diagnostic and treatment algorithms. METHODS: We retrospectively evaluated the patients with deep sternal wound infections at our institution between March 2018 and December 2021. The inclusion criteria were the presence of deep sternal wound infection and complete sternal osteomyelitis. Eighty-seven patients could be included in the study. All patients received a radical sternectomy, with complete microbiological and histopathological analysis. RESULTS: In 20 patients (23%) the infection was caused by S. epidermidis, in 17 patients (19.54%) by S. aureus, in 3 patients (3.45%) by Enterococcus spp., in 14 patients (16.09%) by gram-negative bacteria, while in 14 patients (16.09%) no pathogen could be identified. In 19 patients (21,84%) the infection was polymicrobial. Two patients had a superimposed Candida spp. INFECTION: Methicillin-resistant S. epidermidis was found in 25 cases (28,74%), while methicillin-resistant S. aureus was isolated in only three cases (3,45%). The average hospital stay for monomicrobial infections was 29.93 ± 13.69 days and for polymicrobial infections was 37.47 ± 19.18 (p = 0.03). Wound swabs and tissue biopsies were routinely harvested for microbiological examination. The increasing number of biopsies was associated with the isolation of a pathogen (4.24 ± 2.22 vs. 2.18 ± 1.6, p < 0,001). Likewise, the increasing number of wound swabs was also associated with the isolation of a pathogen (4.22 ± 3.34 vs. 2.40 ± 1.45, p = 0.011). The median duration of antibiotic treatment was 24.62 (4-90) days intravenous and 23.54 (4-70) days orally. The length of antibiotic treatment for monomicrobial infections was 22.68 ± 14.27 days intravenous and 44.75 ± 25.87 days in total and for polymicrobial infections was 31.65 ± 22.29 days intravenous (p = 0.05) and 61.29 ± 41.45 in total (p = 0.07). The antibiotic treatment duration in patients with methicillin-resistant Staphylococci as well as in patients who developed an infection relapse was not significantly longer. CONCLUSION: S. epidermidis and S. aureus remain the main pathogen in deep sternal wound infections. The number of wound swabs and tissue biopsies correlates with accurate pathogen isolation. With radical surgical treatment, the role of prolonged antibiotic treatment remains unclear and should be evaluated in future prospective randomized studies.

PURPOSE: Osteomyelitis of the sternum may arise either as a primary condition or secondary to median thoracotomy after cardiac surgery, with the latter being decidedly more frequent. Deep sternal wound infections appear as a complication of median thoracotomy in 0.2 to 4.4% of cases and may encompass the infection of the sternal bone. To date, there are no exhaustive histopathological studies of the sternal osteomyelitis. METHODS: Our work group developed a surgical technique to remove the complete infected sternal bone in deep sternal wound infections. We therefore prospectively examined the en bloc resected sternal specimens. Seven standard histological sections were made from the two hemisternums. RESULTS: Forty-seven sternums could be investigated. The median age of the patients in the cohort was 66 (45-81) years and there were 10 females and 37 males. Two methods were developed to examine the histological findings, with one model dividing the results in inflammatory and non-inflammatory, while the second method using a score from 0 to 5 to describe more precisely the intensity of the bone inflammation. The results showed the presence of inflammation in 76.6 to 93.6% of the specimens, depending on the section. The left manubrial sections were more prone to inflammation, especially when the left mammary artery was harvested. No further risk factors proved to have a statistical significance. CONCLUSION: Our study proved that the deep sternal wound infection may cause a ubiquitous inflammation of the sternal bone. The harvest of the left mammary artery may worsen the extent and intensity of infection.

Right ventricular rupture after deep sternal wound infection (DSWI) is a rare but fatal complication, and can occur with or without vacuum assisted closure (VAC) therapy. There is currently no strong evidence to suggest whether or not VAC therapy is a contributing factor to this complication. In total, 30 articles were retrieved and assessed through a systematic review strategy from 1953 to 2022. The keywords: 'vacuum assisted closure'; 'VAC'; 'negative pressure wound therapy'; 'deep sternal wound infection'; 'DSWI'; 'right ventricular rupture'; and 'cardiac rupture' were used in the search. Overall, 15 of the included articles satisfied the predefined eligibility criteria. Fatal right ventricular ruptures were reported in 18 (36%) out of 50 cases. In this article, the risk factors, mechanisms and management of right ventricular rupture are discussed. A novel view of the mechanism of VAC-associated right ventricular rupture is highlighted, with a focus on both pre- and intraoperative management.
RESUMEN
Deep sternal wound infection (DSWI) is a relatively complex wound in wound reconstruction surgery. Because plastic surgeons deal with DSWI patients late. The primary healing (healing by first intention) after reconstruction of DSWI is restricted by many preoperative risk factors. The purpose of this study is to explore and analyse the risk factors of primary healing failure in patients with DSWI treated with platelet-rich plasma (PRP) and negative pressure trauma therapy (NPWT). 115 DSWI patients treated with the PRP and NPWT (PRP + NPWT) modality were retrospectively (2013-2021) analysed. They were divided into two groups according to primary healing results after the first PRP + NPWT treatment. Univariate and multivariate analyses were used to compare the data of the two groups to find out the risk factors and their optimal cut-off values were identified by ROC analysis. The primary healing results, debridement history, wound size, sinus, osteomyelitis, renal function, bacterial culture, albumin (ALB), platelet (PLT) between the two groups were significantly different (P < 0.05). Binary logistic regression showed that osteomyelitis, sinus, ALB and PLT were the risk factors affecting primary healing outcomes (P < 0.05). ROC analysis showed that AUC for ALB in the non-primary healing group was 0.743 (95% CI: 0.650-0.836, P < 0.05) and its optimal cutoff value of 31 g/L was associated with primary healing failure with a sensitivity of 96.9% and specificity of 45.1%. AUC for PLT in the non-primary healing group was 0.670 (95% CI: 0.571 ~ 0.770, P < 0.05) its optimal cutoff value of 293 × 109 /L was associated with primary healing failure with a sensitivity of 72.5% and specificity of 56.3%. In the cases included in this study, the success rate of primary healing of DSWI treated with PRP + NPWT was not affected by the most common preoperative risk factors for wound non-union. It is indirectly confirmed that PRP + NPWT is an ideal treatment. However, it should be noted that it will still be adversely affected by sinus osteomyelitis, ALB and PLT. The patients need to be carefully evaluated and corrected before reconstruction.

The effect of diabetes mellitus (DM) on the incidence of postoperative wound complications in patients with coronary artery bypass grafting (CABG) is still unclear. Thus, we performed a meta-analysis of CABG in DM patients to evaluate existing data from both prospective and historical cohorts. The objective of this trial was to assess the relevance and extent of the effect of diabetes on the outcome of previous CABG procedures. Data sources like Embase and Pubmed were found throughout the research, and the language was limited to English through manual search. The searches were performed up to August 2023. The data were extracted from the study of the inclusion/exclusion criteria, the features of the population, the statistical approach and the clinical results. A qualitative evaluation of the qualifying studies has been carried out. Out of the 1874 studies identified, 21 cohort studies were chosen for analysis. Meta-analyses were performed in 258 454 patients (71 351 diabetic and 187 103 non-diabetic). Twenty-one studies on deep sternal wound infections in CABG patients showed a lower rate of deep sternal wound infections in non-diabetes group compared with those with diabetes (OR, 2.13; 95% CI: 1.97, 2.31, p < 0.00001). And 16 studies of superficial wound infections in patients undergoing CABG were found to be associated with a lower rate of superficial injury (OR, 1.93; 95% CI: 1.53, 2.43, p < 0.00001) compared with those with diabetes; In five trials, perfusion time during CABG (MD, 2.31; 95% CI: -0.16, 4.79, p = 0.07) was observed, and there were no significant differences between diabetes and non-diabetes. Currently, there is a higher risk for CABG in diabetes than in non-diabetes patients with sternal infections and superficial injuries. Future randomized trials will concentrate on the treatment of such perioperatively related complications, which will lower the risk of postoperative wound infection in diabetes.
RESUMEN
A meta-analysis research was executed to appraise the effect of platelet-rich plasma (PRP) on sternal wound healing (SWH). Inclusive literature research till April 2023 was done and 1098 interconnected researches were revised. The 11 picked researches, enclosed 8961 cardiac surgery (CS) persons were in the utilised researchers' starting point, 3663 of them were utilising PRP, and 5298 were control. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the effect of PRP on the SWH by the dichotomous approach and a fixed or random model. PRP had significantly lower sternal wound infection (SWI) (OR, 0.11; 95% CI, 0.03-0.34, p < 0.001), deep SWI (OR, 0.29; 95% CI, 0.16-0.51, p < 0.001), and superficial SWI (OR, 0.20; 95% CI, 0.13-0.33, p < 0.001), compared to control in CS persons. PRP had significantly lower SWI, deep SWI, and superficial SWI, compared to control in CS persons. However, caution must be taken when interacting with its values since there was a low sample size of some of the nominated research found for the comparisons in the meta-analysis.

To assess the impact of topical vancomycin (TV) application in decreasing sternal wound infections (SWIs) post cardiac surgery (CS), we lead a meta-analysis. Twenty-three thousand seven hundred and forty five participants had CS at the outset of the investigations, according to a thorough evaluation of the literature done up to November 2022; 8730 of them used TV, while 15 015 were controls. To assess the effectiveness of TV application in lowering SWIs following CS, odds ratios (OR) with 95% confidence intervals (CIs) were computed with dichotomous technique with a fixed- or random-effect model. The TV had significantly lower SWIs post CS (OR, 0.34; 95% CI, 0.20-0.57; P < .001), and deep SWIs post CS (OR, 0.26; 95% CI, 0.11-0.65; P = .004) compared with control as shown in Figures 2 and 3. Yet, there was no significant difference found amongst TV and control in superficial SWIs post CS (OR, 0.30; 95% CI, 0.07-1.30; P = .011). The TV had significantly lower SWIs, and deep SWIs post CS, and no significant difference was found in superficial SWIs post CS compared with control. The low number of included studies in this meta-analysis for superficial SWIs calls for precaution when analysing the outcomes.

Deep sternal wound infection is a severe complication after cardiac surgery. We performed a meta-analysis evaluating the impact of immediate flap and NPWT on mortality and length of hospital stay. The meta-analysis was registered (CRD42022351755). A systematic literature search was conducted from inception to January, 2023, including PubMed, EMBASE, Cochrane Library, ClinicalTrials.gov and EU Clinical Trials Register. The main outcome were in-hospital mortality and late mortality. And additional outcomes were length of stay and ICU stay time. A total of 438 patients (Immediate flap: 229; NPWT: 209) from four studies were included in this study. Immediate flap was associated with lower in-hospital mortality (OR 0.33, 95% CI 0.13-0.81, P = .02) and length of stay (SMD -13.24, 95% CI -20.53 to -5.94, P = .0004). Moreover, pooled analysis demonstrated no significant difference was found in two groups in terms of late mortality (OR 0.64, 95% CI 0.35-1.16, P = .14) and ICU stay time (SMD -1.65, 95% CI -4.13 to 0.83, P = .19). Immediate flap could reduce in-hospital mortality and length of stay for patients with deep sternal wound infection. Flap transplantation as soon as possible may be advised.

Acute mediastinitis is a rare infection that carries high morbidity and mortality. They are complications seen most often with deep sternal wound infections from surgeries with median sternotomies, oropharyngeal and odontogenic infections and esophageal perforations. These conditions should be promptly recognized and treated. Mediastinal granulomas are focal, mass-like lesions commonly resulting from prior granulomatous infections. They are regarded as benign, self-resolving lesions however can cause complications by compression of adjacent mediastinal structures. Chronic fibrosing mediastinitis is a rare, diffuse fibroinflammatory process most often seen with granulomatous infections and carries a worse prognosis than mediastinal granulomas especially when adjacent mediastinal structures are compromised. In this review, we discuss the epidemiology, etiology, clinical presentation, treatment and prognosis of acute mediastinitis, mediastinal granulomas, and chronic fibrosing mediastinitis.

BACKGROUND: Deep sternal wound infections are rare but severe complications after median sternotomy and can be managed with sternal reconstruction. The use of pectoralis major flap (PMF) has traditionally been the first-line approach for flap reconstruction but the advantage in patients' survival when compared to the omental flap (OF) transposition is still not clear. We performed a study-level meta-analysis evaluating the association of the type of flap on postoperative outcomes. METHODS: A systematic search of the literature was performed to identify all studies comparing the postoperative outcomes of PMF versus OF for sternal reconstruction. The primary outcome was postoperative mortality. Secondary outcomes were the occurrence of sepsis, pneumonia, operative time, and length of stay. Binary outcomes were pooled using an inverse variance method and reported as odds ratio (OR) with corresponding 95% confidence interval (CI). Continuous outcomes were pooled using an inverse variance method and reported as standardized mean difference (SMD) with corresponding 95% CI. RESULTS: Four studies with a total of 528 patients were included in the analysis. Overall, 443 patients had PMF reconstruction, and 85 patients had OF reconstruction. Baseline characteristics were similar in both groups. There were no statistically significant differences between PMF patients and OF patients in mortality (OR 0.6 [0.16; 2.17]; p = .09), sepsis (OR 1.1 [0.49; 2.47]; p = .43), pneumonia (OR 0.72 [0.18; 2.8]; p = .11), length of stay (SMD -0.59 [-2.03; 0.85]; p < .01), and operative time (SMD 0.08 [-1.21; 1.57]; p < .01). CONCLUSION: Our analysis found no association between the type of flap and postoperative mortality, the incidence of pneumonia, sepsis, operation time, and length of stay.

OBJECTIVES: To evaluate whether mediastinitis/deep sternal wound infection (Med/DSWI) is more common in ventricular assist device (VAD) with delayed sternal closure (DSC) compared to VAD with primary sternal closure (PSC). METHODS: A literature search was done over the last four decades for studies that addressed this comparison. RESULTS: Two studies met our inclusion criteria, and their results are contradictory. The first study compared 184 VAD recipients with PSC to 180 VAD recipients with DSC. There was no difference in VAD-related infections between DSC and PSC (15% vs. 16%, respectively; odds ratio = 0.965, 95% confidence interval [CI] = 0.525-1.635). The second study compared 464 VAD recipients with PSC to 94 VAD recipients with DSC. The rate of surgical site infection was higher in the DSC patients (12.5% vs. 1.4%, respectively; odds ratio = 10.1; 95% CI = 3.8-27.0). DSC was identified as an independent risk factor for postoperative mortality, but no detailed infection information was given. CONCLUSIONS: There is no clear evidence of the association between DSC, compared to PSC, and Med/DSWI. Therefore, DSC is not an absolute indication for extended systemic antibiotic prophylaxis. The decision to extend the duration of systemic antibiotic prophylaxis should be made on a case-by-case basis, in collaboration with an infectious disease specialist.

BACKGROUND AND AIM: Deep sternal wound infection (DSWI) is a serious complication following cardiac surgery, and demands early intervention as any delay in diagnosis and management may lead to increased morbidity and mortality. DSWI is associated with increased length of hospitalization (LOH) and economic burden in this patient population. The aim of this study was to determine predictors for increased length of hospitalization in patients who underwent the Modified Sternoplasty technique for deep sternal wound infection following cardiac surgery. METHODS: A retrospective study was undertaken on data from patients who underwent the Modified Sternoplasty surgery for DSWI between September 2010 and January 2020. Patients' characteristics that were recorded included medical history, type of the original heart surgery, length of hospitalizations, and risk factors including hyperlipidemia, diabetes mellitus and hypertension, and morbidity and mortality rates following the Modified Sternoplasty. RESULTS: Sixty-eight patients underwent the Modified Sternoplasty surgery with an average length of hospitalization of 24.63 + 22.09 days. Multivariable analysis showed that only gender was considered a predictor of length of hospitalization when controlling for comorbidities, with average length of hospitalization longer for women than men (35.4 vs. 20.9, p = .04). CONCLUSION: The Modified Sternoplasty surgery is a novel surgical technique for managing DSWI complicated by sternal dehiscence with exposed heart and great vessels. Female gender was associated with increased length of hospitalization in our patient cohort, with average length of hospitalization for women almost twice that of males.

OBJECTIVE: The aim of the study is to assess the therapeutic effect and applicability of pectoralis major muscle turnover flap (PMMTF) reconstruction for treatment of deep sternal wound infection (DSWI) after cardiac surgery in infants and children. METHODS: From March 2013 to October 2021, 23 patients with DSWI after cardiac surgery underwent PMMTF reconstruction. The data and outcomes of the patients were retrospectively analyzed. RESULTS: Twenty patients were treated with unilateral PMMTF reconstruction, and three patients were treated by bilateral PMMTF. All of the sternal wounds healed successfully. All patients survived and were discharged without evidence of infection. In a follow-up period, ranging from 15 to 83 months (mean 32.6 months), all patients demonstrated normal development with no limitations to limb movements. There were no signs of chronic sternal infection in all of them. CONCLUSION: PMMTF reconstruction is a simple, feasible, and effective treatment of DSWI after cardiac surgery in infants and children, with minimal developmental problems.

BACKGROUND: Postoperative pain after cardiac surgery is a very important issue and affects recovery, risk of postoperative complications and quality of life. The pain management has been traditionally based on intravenous opioids with growing evidence suggesting the use of opioid-free and opioid-sparing techniques to reduce its adverse effects. CASE PRESENTATION: We report the case of a 75-year-old frail patient underwent awake mediastinal revision with subxiphoid access due to deep sternal wound infection using a pectoralis-intercostal rectus sheath (PIRS) plane block. During the procedure the patient never reported pain receiving acetaminophen 1 g every 8 h for postoperative pain management without others pain relievers. CONCLUSION: Ultrasound guided PIRS block could be an effective and safe analgesic technique to manage sternal and subxiphoid drainage pain in patients undergoing cardiac surgery via subxiphoid approach.

BACKGROUND: We compared postoperative outcomes in hemodialysis (HD) patients who underwent isolated coronary artery bypass grafting (CABG) for multivessel disease using either bilateral or single skeletonized internal thoracic artery.MethodsâandâResults:Among 1,486 patients who underwent isolated CABG between 2002 and 2020, 145 HD patients were retrospectively analyzed. After inverse probability of treatment weighting, there were no significant differences in the preoperative characteristics. No significant differences in 30-day mortality (P=0.551) or postoperative deep sternal wound infection (P=0.778) were observed. However, the bilateral internal thoracic artery grafting group had a lower postoperative stroke rate (0% vs. 4.0%, P=0.019). No significant differences in freedom from all-cause death (P=0.760) and cardiac death (P=0.863) were found. In the multivariate Cox proportional hazards models, bilateral internal thoracic artery grafting was not associated with all-cause death (P=0.246) or cardiac death (P=0.435). CONCLUSIONS: Bilateral internal thoracic artery grafting in HD patients did not improve mid-term outcomes, but it was also not associated with worse postoperative outcomes. Use of the bilateral internal thoracic artery may be an important option in patients with limited conduits to prevent postoperative complications.

Vacuum-assisted closure (VAC) has been used for children with deep sternal wound infections (DSWI); however, the safety and efficiency have not been determined. A meta-analysis was performed for outcomes of VAC therapy in children with DSWI after cardiac surgery. Electronic databases, including PubMed, Scopus, and Cochrane Library CENTRAL were searched systematically from January 1990 to October 2020 for the literature which reported the outcomes of VAC therapy for children with DSWI after cardiac surgery. Meta-regression and subgroup analyses were performed to find risk factors for prolonged length of VAC therapy and hospital stay. Eleven studies were included in this study, involving 217 subjects. VAC therapy was performed due to mediastinitis after congenital heart diseases (CHD) repair. In children with DSWI after cardiac surgery, length of VAC therapy, and hospital stay were 11.1 days (95% CI, 9.6-12.5 days) and 29.8 days (95% CI, 22.8-36.9 days), respectively. Incidence of infectious and wound-related complications was 8.5% (95% CI, 4.1%-13.0%). Overall mortality in this setting was 5.8% (95% CI, 2.5%-9.1%). In conclusion, in children with DSWI after cardiac surgery, length of VAC therapy and hospital stay were 11.1 and 29.8 days, respectively. Overall mortality was 5.8%. Although not significant, delayed chest closure, complex CHD, and Gram-negative bacilli/fungal infections may potentially contribute to prolonged duration of VAC treatment.

Previous studies have reported that the use of incisional negative pressure wound therapy (INPWT) might reduce the incidence of wound infections, although its mechanism remains unknown. We designed a prospective study to explore the effects of INPWT on different stages of the wound healing process. After meeting the inclusion criteria, 108 patients were enrolled. Based on exclusion criteria four patients were excluded and 104 patients were randomised into two groups. INPWT was applied after primary closure of the midline sternotomy in the study group (n = 52), while conventional wound dressing was applied in the control group (n = 52). We documented the incidence of deep sternal wound infections and analysed the pre- and postoperative inflammatory biomarkers and scar size in both groups. No wound infections were observed in the study group compared with six cases (11.1%) in the control group, (P = .026). No significant differences were observed in the inflammatory biomarkers between the groups. Scar size was significantly smaller in the study group. We concluded that INPWT has less effect on the inflammatory phase and appears to have more effect on the proliferation phase through pronounced scar formation.
