Postoperative Surgical Wound Infection Research Articles

Monte Carlo simulations and phantom modeling for spatial frequency domain imaging of surgical wound monitoring.

Postoperative surgical wound infection is a serious problem around the globe, including in countries with advanced healthcare systems, and a method for early detection of infection is urgently required. We explore spatial frequency domain imaging (SFDI) for distinguishing changes in surgical wound healing based on the tissue scattering properties and surgical wound width measurements. A comprehensive numerical method is developed by applying a three-dimensional Monte Carlo simulation to a vertical heterogeneous wound model. The Monte Carlo simulation results are validated using resin phantom imaging experiments. We report on the SFDI lateral resolution with varying reduced scattering value and wound width and discuss the partial volume effect at the sharp vertical boundaries present in a surgical incision. The detection sensitivity of this method is dependent on spatial frequency, wound reduced scattering coefficient, and wound width. We provide guidelines for future SFDI instrument design and explanation for the expected error in SFDI measurements.

Effects of laparoscopic splenectomy on surgical site wound infection in patients with spleen rupture: A meta-analysis.

A meta-analysis was performed to compare the effects of laparoscopic splenectomy (LS) and open splenectomy (OS) for splenic rupture on postoperative surgical site wound infections and postoperative complications. A comprehensive computerised search was conducted for studies comparing LS with OS for the treatment of splenic rupture in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases, with the search including studies published in any language between the creation of the databases and August 2023. Two researchers independently screened the literature and extracted the data. Literature quality was assessed using the Newcastle-Ottawa Scale, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Twenty-two studies involving 1545 patients were included. LS was superior to OS in the following aspects: reduced risk of postoperative surgical site wound infection (OR = 0.19, 95% CI: 0.11-0.34, p = 0.000), shortened hospital stay (standardised mean difference = -1.73, 95% CI: -2.05 to -1.40, p = 0.000), and reduced postoperative complication rate (OR = 0.22, 95% CI: 0.16-0.31, p = 0.000). Compared with OS, LS has a lower rate of postoperative wound infection, shorter hospital stay, and reduced rate of postoperative complications. LS is safe and effective for the treatment of splenic rupture and can be promoted clinically.

Effects of tourniquet on surgical site wound infection and pain after total knee arthroplasty: A meta-analysis.

The application of a tourniquet (TNQ) for haemostasis in total knee arthroplasty (TKA) is controversial and lacking systematic evaluation. This meta-analysis assessed relevant international data to quantitatively evaluate the implications of using TNQ in TKA, further guide clinical diagnosis and treatment, and improve postoperative outcomes. A comprehensive computerised search of PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, VIP, and Wanfang databases was conducted to retrieve randomised controlled trials on the application of TNQ in TKA published from database inception to August 2023. The included data, ultimately comprising 1482 patients in 16 studies, were collated and subjected to meta-analysis using Stata 17.0 software. The results showed that the use of TNQ during TKA led to significantly higher rates of postoperative surgical site wound infection (3.96% vs. 1.79%, odds ratio: 2.15, 95% confidence intervals [CIs]: 1.11-4.16, p = 0.023) and wound pain scores on the first (standardised mean difference [SMD]: 0.65, 95% CI: 0.35-0.94, p < 0.001), second (SMD: 0.66, 95% CI: 0.01-1.31, p = 0.045), and third (SMD: 0.68, 95% CI: 0.31-1.05, pP < 0.001) day after the procedure. In conclusion, the application of TNQ in TKA increases the risk of postoperative surgical site wound infection and worsens short-term postoperative wound pain; therefore, TNQ should be used sparingly during TKA, or its use should be decided in conjunction with the relevant clinical indications and the surgeon's experience.

Study to determine the factors related to patient and surgical procedures influencing the rate of postoperative surgical wound infections

Wound infections continue to be a substantial contributor to postoperative morbidity, responsible for around one-fourth of all nosocomial infections. The human bacteria from the endogenous organ microflora and the extrinsic environment continue to have a role in the development of wound infections. The development of postoperative wound infection has been linked to several different perioperative variables that have been studied in detail. Numerous studies have shown that several surgical procedures are more susceptible to postoperative infection complications because of individual risk factors. The majority of patient- and procedure-related variables have been identified to influence the likelihood of surgical site infections in univariate or multivariate analysis. Preexisting infection, older age, and other dangerous pathogens, smoking, and diabetes is also possible patient-related variables. Procedure-related variables include the length of the surgery, the quality of preoperative skin preparation and poor surgical skill. The goal of this study was to recognize the incidence of postoperative surgical wound infections, which is influenced by patient and surgical technique parameters.

The impact of negative pressure wound therapy on surgical wound infection, hospital stay and postoperative complications after spinal surgery: A meta-analysis.

To systematically assess the effect of negative pressure wound therapy (NPWT) on postoperative surgical wound infection, length of hospital stay and postoperative complications after spinal surgery. Relevant studies on the application of NPWT in spinal surgery were conducted via a computerised database search, including PubMed, EMBASE, Web of Science, MEDLINE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wanfang, from inception to June 2023. The identified literature was rigorously screened and data extraction was performed by two investigators independently. The quality of the relevant studies was evaluated using the Newcastle-Ottawa scale (NOS). The effect size for count data was determined by the odds ratio (OR), while the impact size for measurement data was expressed as the standardised mean difference (SMD). The 95% confidence interval (CI) was calculated for each effect magnitude. Stata 17.0 software was used for the meta-analysis. Ten papers, totalling 1448 patients, were finally included. This study demonstrated that NPWT led to a statistically significant reduction in the occurrence of postoperative surgical wound infections (OR: 0.377, 95% CI: 0.238-0.598, p < 0.001), fewer postoperative complications (OR: 0.526, 95% CI: 0.360-0.770, p = 0.001) and a shortened hospital stay (SMD: -0.678, 95%CI: -1.324 to -0.031, p = 0.040) after spinal surgery compared with the control group. When compared with other treatment approaches, NPWT also demonstrated a substantial reduction in surgical wound infections and postoperative complications, as well as a shorter duration of hospitalisation after spinal surgery.

A meta-analysis comparing the effects of cemented and uncemented prostheses on wound infection and pain in patients with femoral neck fractures.

To providing evidence-based recommendations for surgery in patients with femoral neck fractures, a meta-analysis was conducted to comprehensively evaluate the effects of cemented and uncemented prostheses on postoperative surgical site wound infection and pain in these patients. Relevant studies on the use of cemented prostheses in femoral neck fractures were retrieved from PubMed, EMBASE, Cochrane Library, Ovid, CNKI, and Wanfang databases from the time of their establishment until March 2023. Two authors independently screened and extracted data from the included and excluded literature according to predetermined criteria. Review Manager 5.4 software was used to perform meta-analyses on the collected data. A total of 27 articles comprising 34 210 patients (24 646 cases in the cemented group and 9564 cases in the uncemented group) were included in the final analysis. The results of the meta-analysis showed that, compared with the uncemented group, cemented prostheses significantly reduced the incidence of surgical site wound infections (odds ratio [OR]: 0.75, 95% confidence interval [CI]: 0.64-0.88, p < 0.001) and relieved surgical site wound pain (standardised mean difference: -0.76, 95% CI: -1.12-0.40, p < 0.001), but did not reduce the incidence of pressure ulcers after surgery (OR: 0.50, 95% CI: 0.20-1.26, p = 0.140). Therefore, existing evidence suggests that the use of cemented prostheses in femoral neck fracture surgery can significantly reduce the incidence of surgical site wound infections and relieve surgical site wound pain, which is worthy of clinical recommendation.

Influence of closed-incision negative-pressure wound therapy on the incidence of surgical site wound infection in patients undergoing spine surgery: A meta-analysis.

The present meta-analysis was conducted to comprehensively assess the impact of closed-incision negative-pressure wound therapy (ciNPWT) on the incidence of surgical site infections (SSIs) in patients undergoing spinal fusion surgery, thereby aiming to provide evidence-based support for the prevention of postoperative wound infections during spinal surgery. Relevant studies pertaining to the application of ciNPWT in spinal surgery were retrieved through searches of the PubMed, Embase, MEDLINE and Cochrane Library databases, spanning from their inception to May 2023. The literature screening and data extraction were performed by two researchers based on predefined inclusion and exclusion criteria, followed by a quality assessment of the included studies. Meta-analyses were performed using the odds ratios (ORs) and standardised mean differences (SMDs) as effect variables. RevMan 14.0 and STATA 17.0 were employed for meta-analysis of the extracted data. In total, eight articles involving 1198 patients, including 391 in the experimental group and 807 in the control group, were included. The meta-analysis results revealed that ciNPWT significantly reduced the incidence of SSIs in patients undergoing spinal fusion surgery (OR, 0.39; 95% CI: 0.22-0.67, p = 0.0007); however, it did not lead to a reduction in hospital stay duration (SMD: -0.48, 95% CI: -0.98 to 0.01, p = 0.06). Existing evidence suggests that ciNPWT has a positive impact on patients undergoing spinal fusion surgery, as it significantly reduces the incidence of postoperative surgical site wound infections; however, it does not result in a shorter hospital stay for patients.

Comparison of the Outcomes of Oral Versus Nasal Endotracheal Intubation in Neonates and Infants Undergoing Cardiac Surgery: A Randomized Controlled Study

The choice of oral or nasal endotracheal intubation in children undergoing cardiac surgery is affected by several factors. This study compared the outcomes of oral versus nasal intubation in neonates and infants who underwent open cardiac surgery. A randomized, controlled, open-labeled study. At a university hospital. A total of 220 infants and neonates who underwent cardiac surgery. Patients were allocated randomly to oral or nasal intubation. The primary outcome measure was postoperative fentanyl consumption (µg/kg/h) by intubated patients. Secondary outcome measures were the increase in heart rate (HR) from baseline during intubation, the time consumed for intubation, accidental intraoperative extubation, the occurrence of epistaxis, time to extubation, the onset of full oral feeding, intensive care unit (ICU) and hospital lengths of stay, and the incidence of postoperative complications (the need for reintubation, stridor, pneumonia, wound infection). The mean (SD) postoperative fentanyl consumption of intubated patients (the primary outcome) was significantly lower (p < 0.001) in the nasal intubation group (0.53 ± 0.48) µg/kg/h compared with the oral intubation group (0.82 ± 0.20) µg/kg/h. The median (IQR) time needed for the intubation (31.5, 27-35 v 16, 14.8-18 seconds) was significantly (p < 0.001) longer, and the mean (SD) increase in HR (beats/min) from baseline during intubation (18 ± 5 v 26 ± 7) was significantly (p < 0.001) lower in the nasal intubation group compared to the oral intubation group. The incidence of inadvertent intraoperative extubation was significantly (p=0.029) higher in the oral (n=6, 6.1%) than in the nasal (n=0, 0%) intubation group. The median (IQR) time to extubation (14, 12.6-17.2 v 20.5, 16.4-25.4 hours) and the ICU length of stay (27, 26-28 v 30, 28-34 hours) were significantly (p < 0.05) shorter in the nasal group compared to the oral group. The median (IQR) time to onset of full oral feeding was significantly (p=0.031) shorter in the nasal intubation group (3, 1-6 days) compared to the oral intubation group (4, 2-7 days). There were no significant differences between the oral and nasal groups in the duration of hospital stay and the indices for reintubation, postintubation stridor, pneumonia, and surgical wound infection. The nasal route for intubation is associated with less postoperative fentanyl consumption, earlier extubation, lower incidence of accidental extubation, and earlier full oral feeding than oral intubation. The nasal route is not associated with an increased risk of postoperative pneumonia or surgical wound infection.

Effect of laparoscopic pancreaticoduodenectomy on the incidence of surgical-site wound infection: A meta-analysis.

A meta-analysis was conducted to assess the impact of robotic and laparoscopic pancreaticoduodenectomies on postoperative surgical site wound infections. A comprehensive computerised search of databases, such as PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wanfang Data, was performed to identify studies comparing robotic pancreaticoduodenectomy (PD) with laparoscopicPD. Relevant studies were searched from the inception of the database construction until April 2023. The meta-analysis outcomes were analysed using odds ratios (OR) with corresponding 95% confidence intervals (CI). The RevMan 5.4 software was used for the meta-analysis. The findings of the meta-analysis showed that patients who underwent laparoscopic PD had a significantly lower incidence of surgical-site wound (16.52% vs. 18.92%, OR: 0.78, 95% CI: 0.68-0.90, P = .0005), superficial wound (3.65% vs. 7.57%, OR: 0.51, 95% CI: 0.39-0.68, P < .001), and deep wound infections (1.09% vs. 2.23%, OR: 0.53, 95% CI: 0.34-0.85, P = .008) than those who received robotic PD. However, because of variations in sample size between studies, some studies suffered from methodological quality deficiencies. Therefore, further validation of this result is needed in future studies with higher quality and larger sample sizes.

Effect of endoscopic loop ties in acute appendicitis on wound infection rate: A meta-analysis.

A meta-analysis study to measure the consequence of endoscopic loop ties (ELT) in acute appendicitis (AA) on wound infection rate. A comprehensive literature inspection till February 2023 was applied and 2765 interrelated studies were reviewed. The 27 chosen studies enclosed 15 093 subjects with AA in the chosen studies' starting point, 7141 of them were ELT, and 7952 were open surgery. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the effect of ELT in AA on wound infection rate by the dichotomous and continuous styles and a fixed or random model. Open surgery had a significantly higher postoperative surgical site wound infection (SSWI). (OR, 1.41; 95% CI, 1.09-1.83, P = 0.009) with low heterogeneity (I2 = 34%) compared to ELT in AA subjects. Although no significant difference was detected between open surgery and ELT in intra-abdominal abscess rate (OR, 0.88; 95% CI, 0.56-1.40, P = 0.59) with moderate heterogeneity (I2 = 51%) in AA subjects. Open surgery had a significantly higher postoperative SSWI, however, no significant difference was found in intra-abdominal abscess rate compared to ELT in AA subjects. However, caused by the small sample sizes of several chosen studies for this meta-analysis, care must be exercised when dealing with its values.

The Correlation between Mechanobiology and Fracture Healing; Osteosynthesis, Biomaterial Optimization and TRIZ Design Principles to Develop Ameliorative Implants for Reconstruction of Median Osteochondrotomy of the Sternum.

The application of stainless-steel wire is still the "standard of care" and is believed to be the "gold standard" after trans-sternal thoracotomy. To overcome postoperative instability and surgical wound infection there had been the development of a variety of circumferential, Hemi-circular, and surface on-lay implant designs to enhance bone healing of the sternum particularly in compromised patients. This fundamental descriptive theoretical research study probes into biology and effects of mechanical environment on fracture healing in general and various types of ossifications that may occur during healing of the sternum. Following surgical anatomy of the sternum, the biology of fracture (osteotomy) healing, an update on the conventional and newer biomaterials, and role of 3D printing in custom additive manufacturing of the surgical implants have been discussed in detail. There is discussion on design principles and structural optimization in-line with patient-specific and patient-appropriate osteosynthesis. In support, the Teorija Rezhenija Izobretatelskikh Zadatch engineering principles have been applied to improve implant design in the face of the current strategies to relieve some of the recalcitrant deficiencies underlying the mechanics of the most favored implant for the reconstruction of the sternum. Several scientific domains of the engineering design principles and fracture healing processes have been connected leading to four newly conceptualized prototype designs for the reconstruction of the sternum. In conclusion, despite increased knowledge of the fracture healing process there are limited means to mitigate the adverse mechanical environment experienced by the healing sternum. There are uncertainties how to transfer the well-known facts of tissue strain during healing from the experimental platform to the operating table at the time of fracture fixation and reconstruction of the sternum for its optimal healing.

Assessment of Bundle of Measures Perioperatively to Decrease the Incidence of Surgical Site Wound Infection in Patients Undergoing Abdominal Hysterectomies

Background: Surgical site infections (SSIs) are the second most common reason for unplanned hospital readmissions after hysterectomy and result in increased morbidity and health care costs. The estimated rate of SSI after hysterectomy varies between 1% and 4%. The objective of the study is to investigate if a bundle of perioperative measures (as stated earlier) reduces down the incidence of post-operative surgical site wound infection after abdominal hysterectomy. Materials and Methods: The present prospective study was carried out on total 200 women who were undergo hysterectomy in the operation theater of Department of Obstetrics and Gynecology of IPGMER and SSKM Hospital due to gynecological conditions requiring hysterectomy. Four perioperative bundles of measures are considered – 1. chlorhexidine gluconate and Cetrimide solution (Savlon) wash of the operative field 1 h before the operation, 2. administration of single dose antibiotic (Inj. Ceftriaxone 1 g intravenous) 1 h or less before the incision, 3. vaginal wash with povidone-iodine, and 4. sterile dressing is to be maintained and removed postoperatively after 48 h. Result: We found that in case, 94 (94.0%) patients had Ceftriaxone and 6 (6.0%) patients had clindamycin and gentamicin. In control, 96 (96.0%) patients had ceftriaxone and 4 (4.0%) patients had clindamycin and gentamicin. Association of choice of antibiotic versus group was not statistically significant (P = 0.5164). In case, 6 (6.0%) patients had wound gaping. In control, 11 (11.0%) patients had wound gaping. Association of wound gaping versus group was statistically significant (P = 0.048). Conclusion: The present study found that hospital stay was more in control compared to case which was statistically significant. Fever was more in control compared to case which was statistically significant. In this study, local wound discharge was more in control compared to case which was statistically significant. It was found that wound gaping was more in control compared to case which was statistically significant.

Initial Experience of 60 Cases Pure-Laparoscopic Donor Hepatectomy in Cleveland Clinic

Introduction: The adoption of pure-laparoscopic donor hepatectomy (PLDH) has been slow in North America because of the associated technical complexity and concerns for donor safety. This study aimed to report our initial 60 PLDH and elaborate on the understanding of the pre-requisites for the successful introduction of PLDH. Method: Retrospective review during the initial 2 years after the introduction Results: Between August 2019 and August 2021, 60 PLDH were performed; 33 patients donated left lobe grafts, 25 cases were right lobe grafts, 1 case was right posterior section graft, and 1 patient donated left lateral segment. The characteristics of 60 PLDH were summarized in Table. The median operative time was 345 minutes in the left lobe group and 348 minutes in the right lobe group, respectively. No cases required intraoperative blood transfusion or open conversion. Two patients developed a postoperative surgical wound infection, one patient required postoperative blood transfusion, one patient required laparoscopic portal vein venoplasty for portal vein stenosis. The median in-patient stay was 5 days (4-9) and there were no 30-day readmissions. Conclusions: Seamless introduction of OLDH and donor safety were achieved by: 1) minimizing the learning curve through proctorship from experienced surgeon, 2) establish a dedicated surgical team and accumulate adequate surgical experience in living donor hepatectomy and laparoscopic hepatectomy, especially major hepatectomy, 3) active institutional support to have proper instrumentation necessary for operational efficiency, and 4) proper master planning including the ready availability of a crisis management protocol and team in case of an emergency.Tabled 1Left Lobe (N=33, 55.0%)Right lobe (N=25, 41.7%)Age34 (18-58)43 (25-58)male/Female22/117/18Height178 (158-196)168 (155-189)Weight82 (61-119)76 (54-122)BMI27.6 (21.3-36.6)27.7 (21.3-39.7)Operative time345 (256-501)348 (264-450)EBL200 (50-600)150 (30-500)Complicatio33LOS5 (4-8)5 (4-9) Open table in a new tab

The Kempe incision for decompressive craniectomy, craniotomy, and cranioplasty in traumatic brain injury and stroke.

Decompressive craniectomy (DC) is an effective, lifesaving option for reducing intracranial pressure (ICP) in traumatic brain injury (TBI), stroke, and other pathologies with elevated ICP. Most DCs are performed via a standard trauma flap shaped like a reverse question mark (RQM), which requires sacrificing the occipital and posterior auricular arteries and can be complicated by wound dehiscence and infections. The Ludwig Kempe hemispherectomy incision (Kempe) entails a T-shaped incision, one limb from the midline behind the hairline to the inion and the other limb from the root of the zygoma to the coronal suture. The authors' objective in this study was to define their implementation of the Kempe incision for DC and craniotomy, report clinical outcomes, and quantify the volume of bone removed compared with the RQM incision. A retrospective review of a single-surgeon experience with DC in TBI and stroke was performed. Patient demographics, imaging, and outcomes were collected for all DCs from 2015 to 2020, and the incisions were categorized as either Kempe or RQM. Preoperative and postoperative CT scans were obtained and processed using a combination of automatic segmentation (in Python and SimpleITK) with manual cleanup and further subselection in ITK-SNAP. The volume of bone removed was quantified, and the primary outcome was percentage of hemicranium removed. Postoperative surgical wound infections, estimated blood loss (EBL), and length of surgery were compared between the two groups as secondary outcomes. Cranioplasty data were collected. One hundred thirty-six patients were included in the analysis; there were 57 patients in the craniotomy group (44 patients with RQM incisions and 13 with Kempe incisions) and 79 in the craniectomy group (41 patients with RQM incisions and 38 Kempe incisions). The mean follow-up for the entire cohort was 251 ± 368 days. There was a difference in the amount of decompression between approaches in multivariate modeling (39% ± 11% of the hemicranium was removed via the Kempe incision vs 34% ± 10% via the RQM incision, p = 0.047), although this did not achieve significance in multivariate modeling. Wound infection rates, EBL, and length of surgery were comparable between the two incision types. No wound infections in either cohort were due to wound dehiscence. Cranioplasty outcomes were comparable between the two incision types. The Kempe incision for craniectomy or craniotomy is a safe, feasible, and effective alternative to the RQM. The authors advocate the Kempe incision in cases in which contralateral operative pathology or subsequent craniofacial/skull base repair is anticipated.

PREDICTIVE FACTORS OF INCISIONAL HERNIA AFTER NEPHRECTOMY

Abstract INTRODUCTION Kidney diseases’ surgical approach is multiple, tending to reduce postoperative complications such as incisional hernia, a complication with an incidence around 5-15% and which usually appears after the first year of surgery, being this the possible trigger of serious pathologies that make essential the need to identify predictive factors of its appearance. MATERIAL AND METHODS A retrospective observational study was carried out in 269 patients undergoing nephrectomy (partial or radical) or nephroureterectomy between 2004 and 2018, with the aim of identifying possible predictive factors of incisional hernia after these surgeries. Preoperative (epidemiological and comorbidities), intraoperative (type of surgery, approach and closure, duration) and postoperative data (different possible complications) were taken into account. A univariate and multivariate analysis were performed, using Chi-square test and logistic regression, respectively. RESULTS The median follow-up time was 52.2 months (SD = 39.5), time in which 22 patients had an incisional hernia (8.2%), showing this association with preoperative and postoperative variables. As preoperative data COPD, obesity, ASA and a history of previous laparotomy were related in the univariate analysis, while only obesity was associated in the multivariate analysis (p = 0.003); among postoperative items surgical wound infection, postoperative pulmonary complication, seroma and the need for transfusion and reoperation showed association in the univariate analysis, but only surgical wound infection was the one confirmed in the multivariate analysis (p = 0.049). CONCLUSIONS Obesity and surgical wound infection were proved to be the main predictive factors for the appearance of incisional hernia after nephrectomy.

Postoperative Orthopedic Surgical Site Infection Antibiogram of dr. Soebandi Hospital, Jember in 2019

&lt;span&gt;Surgical site infection (SSI) is a microbial infection of the surgical wound within 30 days of operation or one year after surgery if an implant is placed in a patient. The incidence level of postoperative orthopedic SSI range to 71%. An increase in antibiotic-resistant bacteria causes the treatment of postoperative orthopedic surgical wound infections to be less effective, so there is an increase in morbidity, mortality, length of stay, and economic burden on hospital resources.&lt;/span&gt;&lt;span lang="EN-ID"&gt;A&lt;/span&gt;&lt;span lang="IN"&gt;ntibiogram&lt;/span&gt;&lt;span lang="EN-ID"&gt; were used to guide&lt;/span&gt;&lt;span&gt;the clinician and pharmacis&lt;/span&gt;&lt;span lang="IN"&gt;t &lt;/span&gt;&lt;span lang="EN-ID"&gt;selected&lt;/span&gt;&lt;span&gt;the best empiric antimicrobial treatment in the event of pending microbiology culture and susceptibility results&lt;/span&gt;&lt;span lang="IN"&gt; to overcome the disadvantages of antibotic-resistant bacteria&lt;/span&gt;&lt;span&gt;.&lt;/span&gt;&lt;span&gt; This study aimed to form a postoperative orthopedic SSI antibiogram of dr.

Of the 34 isolates, 25 were found to be positive for bacterial growth, while nine were negative. Twenty-two bacteria were Gram-negative and others were Gram-positive. The bacteria were tested against beta-lactam and non&lt;/span&gt;&lt;span lang="IN"&gt;-&lt;/span&gt;&lt;span&gt;beta lactam antibiotics.&lt;/span&gt;&lt;span&gt;From antibiogram, showed that Gram-negative bacteria sensitive to the meropenem and resistant to cefotaxime. While, gram-positive bacteria showed sensitivity to doxycycline and resistant to erythromycin and penicillin.&lt;/span&gt;

Bacteriological profile of surgical site infections and their antibiogram

Surgical site infection (SSI) is one of the most common postoperative complications that is encountered in the clinical and surgical practice and it is also the most important cause of significant postoperative morbidity and mortality. The study puts in an effort to determine the incidence of surgical site infections in clean, clean contaminated and contaminated surgeries in our setting along with the factors related to patient and surgical procedures influencing the rate of postoperative surgical wound infections and determine bacteriological profile with antimicrobial susceptibility patterns of the isolates.

Antimicrobial Prophylaxis in Clean Pediatric Surgical Procedures: A Necessity or Redundancy?

BackgroundThe clinical utility of antimicrobial prophylaxis in clean pediatric surgical cases remains enigmatic. The present study aims to evaluate the prevalence of surgical site infections in instances where antibiotic prophylaxis is not employed prior to clean pediatric surgical procedures.MethodsA retrospective cross-sectional study that included data of all pediatric clean surgical procedures from January 2018 till January 2020 was conducted. All children undergoing clean surgical procedures who did not receive antibiotics at least two weeks prior to the procedure were included in the study. The exclusion criteria included patients with congenital heart disease, ventriculoperitoneal shunt, nephrotic syndrome, immunodeficiency, and prior administration of antimicrobial prophylaxis. All patients were followed for two to four weeks for any signs of surgical site infections.ResultsOf the 178 patients included, 119 were male and 59 were female, with the mean age hovering at 8.19 ± 2.87 years. Orchidopexy and herniotomy were the most commonly performed surgical procedures, and were performed in 56 (31.46%) and 54 (30.33%) patients, respectively. Only one case of postoperative surgical site wound infection was reported, accounting for a prevalence rate of 0.56%.ConclusionIn clean pediatric surgical procedures, the risk of surgical site infections is exceedingly low. The unnecessary use of antibiotics in children can cause deleterious adverse effects and promote antimicrobial resistance. In a carefully selected pediatric population, administration of antibiotic prophylaxis might confer no added benefit.

Incidence, types and outcomes of sternal wound infections after cardiac surgery in Saudi Arabia. A retrospective medical chart review.

Objectives:To determine the incidence, types, risk factors, identify organisms, and assess outcomes of surgical wound infections (SWIs) after cardiac surgery at a tertiary hospital in Riyadh, Saudi Arabia.Methods:This historical cohort study reviewed the chart of patients who underwent cardiac surgery at King Khalid University Hospital, Riyadh, Saudi Arabia between January 2009 and December 2014. The proforma contained personal data, comorbidities, type of surgery, microbiological analysis, and management outcomes.Results:A total of 1241 patients were enrolled in the study comprising 1,032 (83.2%) men and 209 (16.8%) women. Forty (3.2%) patients developed SWI, of which 32 (2.5%) were superficial and 8 (0.7%) were deep. Gender, obesity, diabetes mellitus, non-use of statins, and coronary artery bypass graft (CABG) surgery were not significant predictors of infection in the study. Methicillin-susceptible Staphylococcus aureus was isolated predominantly in 45%, followed by Klebsiella and Pseudomonas species. Methicillin-resistant Staphylococcus aureus, Enterococcus faecium, and extended β-lactamase-producing gram-negative organisms were pathogens isolated in last 3 years of the review. Simple and vacuum assisted closure therapies led to complete resolution in 32 (80%) patients, while 8 (20%) developed sternal osteomyelitis. All patients survived except one with a deep SWI who died of uncontrolled sepsis.Conclusion:Despite the low incidence of postoperative SWIs, the risk of sternal osteomyelitis development persists. Meticulous choice of CABG components and appropriate postoperative management, especially detecting early signs of SWI could contribute to lower its incidence and complications.
