Forced-Air Warming Devices and the Risk of Surgical Site Infections

The potential that forced-air warming systems may increase the risk of surgical site infections (SSIs) by acting as a vector or causing unwanted airflow disturbances is a concern to health care providers. To investigate this potential, we examined the literature to determine whether forced-air warming devices increase the risk of SSIs in patients undergoing general, vascular, or orthopedic surgical procedures. We examined 192 evidence sources, 15 of which met our inclusion criteria. Most sources we found indirectly addressed the issue of forced-air warming and only three studies followed patients who were warmed intraoperatively with forced-air warming devices to determine whether there was an increased incidence of SSIs. All of the sources we examined contained methodological concerns, and the evidence did not conclusively suggest that the use of forced-air warming systems increases the risk of SSIs. Given the efficacy of these devices in preventing inadvertent perioperative hypothermia, practitioners should continue to use and clean forced-air warming systems according to the manufacturer’s instructions until well-conducted, large-scale trials can further examine the issue.     

Surgical site infection after pediatric spinal deformity surgery

The incidence of surgical site infection (SSI) after spinal deformity surgery for adolescent idiopathic scoliosis ranges from 0.5–6.7%. The risk of infection following spinal fusion in patients with neuromuscular scoliosis is greater, with reported rates of 6.1–15.2% for cerebral palsy and 8–41.7% for myelodysplasia. SSIs result in increased patient morbidity, multiple operations, prolonged hospital stays, and significant financial costs. Recent literature has focused on elucidating the most common organisms involved in SSIs, as well as identifying modifiable risk factors and prevention strategies that may decrease the rates of infection. These include malnutrition, positive urine cultures, antibiotic prophylaxis, surgical site antisepsis, antibiotic-loaded allograft, local application of antibiotics, and irrigation solutions. Acute and delayed SSIs are managed differently. Removal of instrumentation is required for effective treatment of delayed SSIs. This review article examines the current literature on the prevention and management of SSIs after pediatric spinal deformity surgery.     

Risk factors for surgical site infection after major hepatobiliary and pancreatic surgery

Major hepatobiliary and pancreatic (HP) surgeries are complex procedures associated with a high incidence of surgical site infection (SSI) and are commonly performed in patients with cancer in Japan. This study was performed to investigate the risk factors for SSI, including incisional and organ/space SSI, in HP surgery. The following procedures were included in the study: hepatectomy with and without biliary tract resection, pancreatectomy [pancreaticoduodenectomy (PD), others], and open cholecystectomy. In total, 735 patients were analyzed. The incidence of SSI was 17.8% (incisional, 5.2%; organ/space, 15.5%; both 2.9%). The highest incidence of SSI was observed in patients who underwent hepatectomy with biliary tract resection (39.1%), followed by pancreatectomy (PD, 28.8%; others, 29.8%). Almost all SSIs after these three procedures were classified as organ/space (39.1%, 25.0%, and 27.7%, respectively), and these procedures were risk factors for not only total SSI but also organ/space SSI in the multivariate analysis. An American Society of Anesthesiologists physical status of ≥3 was a risk factor for incisional SSI. Preoperative biliary drainage, prolonged surgery, concomitant surgery, and massive intraoperative bleeding were associated with SSI. In conclusion, the main type of SSI was organ/space SSI after HP surgery, and different risk factors were identified between organ/space and incisional SSI. Procedure-related factors and preoperative biliary drainage were independent risk factors for SSI. To prevent SSI, the indication for preoperative biliary drainage should be carefully evaluated in patients undergoing HP surgery.     

Analysis of risk factors for surgical-site infections in 276 oral cancer surgeries with microvascular free-flap reconstructions at a single university hospital

The purpose of this study was to elucidate the risk factors for surgical-site infection (SSI) in oral cancer surgery with microvascular free-flap reconstructions and to propose appropriate SSI prevention. There were 276 patients who underwent oral cancer surgery with microvascular free-flap reconstructions at the Department of Oral and Maxillo-facial Surgery of Tokai University Hospital. The following variables were assessed as risk factors for SSIs: preoperative variables, including age, sex, body mass index, American Society of Anesthesiologist’s (ASA) score, debilitating comorbidities, smoking, alcohol consumption, and Union Internationale Contre le Cancer Tumor Node Metastasis (UICC-TNM) classification; and operative variables, including duration of surgery, amount of blood loss, quantity of blood transfusion, tracheostomy, area of neck dissection, and previous chemotherapy. Statistical analysis was conducted to determine whether these factors constitute risks for SSI. Total overall SSI rate was 40.6% (112/276). When the occurrence of SSI was compared with the variables, ASA score (P = 0.036), T stage (P = 0.013), duration of surgery (P < 0.001), blood loss (P = 0.001), blood transfusion (P = 0.01), and area of neck dissection (P = 0.009) showed statistical significance. Analysis of these variables with a logistic regression model yielded ASA score and duration of surgery as significant factors. There was a tendency for blood loss and duration of surgery to increase in patients with a high T stage. A high T stage not only broadens the resection area and increases surgical invasiveness, it also increases susceptibility to dead space after microvascular reconstruction for oral cancer. Particular care in treating the wound should be taken in surgical patients with high T-stage scores. The occurrence of SSI is of particular concern in oral cancer surgery in patients with high ASA scores.     

Surgical site infection surveillance after open gastrectomy and risk factors for surgical site infection

Surgical site infection (SSI) surveillance was examined in gastric cancer patients who had undergone an open gastrectomy between 1997 and 2003 at Keio University Hospital in Tokyo, Japan. National Nosocomial Infections Surveillance (NNIS) reports and several studies have discussed SSI risk factors, but only open gastrectomy was analyzed by regression analysis. The purpose of this study was to examine these issues by performing a regression analysis for the prediction of SSI. SSI was defined by the surgical patient component according to the NNIS system (1999) produced by the Centers for Disease Control and Prevention. Patients undergoing an open gastrectomy were followed up and monitored for SSIs. Risk factors for SSI, after all factors were considered, were studied using single and multivariate analysis. The study enrolled 984 patients who had undergoing an open gastrectomy. Using multivariate and logistic regression analysis, the duration of the operation was identified as the only risk factor for SSI at open gastrectomy. Although numerous potential risk factors in surgical patients were examined, the duration of the operation was the only significant risk factor for SSIs after open gastrectomy. Part of this study was presented at the 76^th conference of the Infectious Disease Society An erratum to this article is available at .     

Reducing Surgical Site Infections by Bundling Multiple Risk Reduction Strategies and Active Surveillance

Postoperative surgical site infections (SSIs) are serious health care-associated infections that contribute to higher rates of mortality. Methicillin-resistant Staphylococcus aureus (MRSA) is an increasingly common cause of SSIs. A quality improvement intervention was developed to identify surgical patients with nasal colonization of MRSA, treat them with mupirocin, and introduce a new preoperative skin antisepsis protocol using 2% chlorhexidine gluconate cloths. The total number of SSIs was reduced by 63%, and MRSA SSIs decreased by 78%. Preoperative MRSA screening and treatment and the preoperative skin antisepsis protocol were smoothly integrated into the facility workflow and well accepted by patients. This intervention saved two community hospitals an estimated $240,000.     

Differences in Intraoperative Prep Solutions: A Retrospective Chart Review

Surgical site infections (SSIs) are the most common type of health care-associated infection in surgical patients. We wanted to identify which intraoperative prep solution used in our health network for adult open abdominal surgical procedures resulted in the lowest incidence of SSI 30 days after surgery. In addition, we wanted to know specifically how parachoroxylenol compared with chlorhexidine gluconate, povidone-iodine, and 0.7% iodine and 74% isopropyl alcohol as an intraoperative prep solution. We conducted a retrospective medical record review of 162 consecutive patients ages 18 years and older who had undergone elective open abdominal procedures from December 2008 to December 2010 at four acute care community hospitals within an integrated, tertiary health network in the southeastern United States. No SSIs occurred after procedures in which parachoroxylenol intraoperative prep solution was used (n = 71), whereas five SSIs occurred after procedures in which other prep solutions (ie, chlorhexidine gluconate [no SSIs], povidone-iodine [two SSIs], and 0.7% iodine and 74% isopropyl alcohol [three SSIs]) were used (n = 91). A chi-square test indicated a significant difference in the incidence of SSIs among patients prepped with parachoroxylenol intraoperative prep solution compared to patients prepped with the other solutions.     

Surgical nursing – mastectomy

ABSTRACT

Surgical nursing roles include anaesthetist, surgical assistant and circulating nurse. Managing theatre is often the job of the veterinary nurse and successful management of these roles are vital for patient care and good surgical outcome. The nursing management of a dog with mammary tumours admitted for a second mastectomy is discussed. Pre-operative nursing interventions including blood testing, radiographs and intravenous fluid therapy is discussed, as are pre-anaesthetic clipping and the risk of surgical site infection (SSI). SSIs are also discussed in relation to surgical attire and despite a lack of evidence for some items reducing SSIs, they are still recommended to prompt theatre discipline. The nurse’s role as a surgical assistant is discussed and the importance of good technique to ensure tissue vitality and reduced SSIs. Passive drain care is considered alone with the associated risks of ascending infection.     

The evolution of laparoscopy in abdominal surgery: A meta-analysis of the effect on infectious outcomes

Abstract

Background: Laparoscopic surgery has been recommended as an effective strategy because of its advantages in decreasing abdominal surgical site infections (SSIs). The aim of this study was to assess the effect of laparoscopy on superficial and organ/space SSIs compared with open surgery in hollow-viscus procedures over time. Study design: Data on SSIs from randomized-controlled trials (RCTs) evaluating open versus laparoscopic abdominal surgeries were extracted from the Cochrane Database Reviews. Re-analysis of these data was performed to assess infections. Heterogeneity was also explored. A subgroup analysis was performed according to elective/emergency surgery status. Results: Data from 72 RCTs including 8218 patients were collected (4116 patients in the laparoscopic group and 4102 patients in the open group). For superficial SSI, the pooled RD was -4.4% (95% CI: -5.4% to -3.3%), which indicated a lower risk in the laparoscopic group. For organ/space SSI, the pooled RD was 0.5% (95% CI: -0.1% to 1%), which indicated similar rates between the groups. Changes in SSI frequency had occurred over time. Conclusion: Laparoscopic surgery significantly decreases the risk of superficial SSI but does not affect the risk of organ/space SSI. Experience with technique improves outcomes.

Simple methodology for detecting time shifts in surgical site infections: a study in digestive,breast, and thoracic surgery

To simplify the data mining surveillance system for the monitoring of surgical site infections (SSIs), electronic analysis of a total of 3100 patients was done. Using Layered Analyses, the Cross-Table option of a globally available software detected emerging or disappearing SSIs according to specific parameters. This methodology may facilitate the detection of SSI shifts.     

Awareness of surgical site infections for advanced practice nurses

A primary concern in healthcare today is the prevention of infection. Surgical site infections (SSIs) are the leading type of infection among hospitalized patients. Advanced practice nurses play a vital role in patient care, and those who incorporate best practice standards can reduce the morbidity and mortality associated with SSIs. The Centers for Disease Control and Prevention have published recommendations for prevention of SSIs. This article reviews current literature regarding the prevention of SSIs and how critical care practitioners can incorporate these scientifically tested recommendations into their practice.     

Nonconcordance with surgical site infection prevention guidelines and rates of surgical site infections for general surgical, neurological, and orthopedic procedures

Surgical site infection (SSI) is a common and preventable complication of surgery, but the relative importance of individual measures recommended by guidelines has not been determined. Elective general surgical, neurological, and orthopedic procedures requiring antibiotic prophylaxis from a 3-month period were retrospectively studied to determine concordance with SSI prevention guidelines and to identify factors which predicted the development of SSIs. A total of 216 surgeries were reviewed, with 18 SSIs (8.3%). A mean of 1.4 antibiotic prophylaxis errors per surgery were identified, with correct antibiotic type identified for 64%, antibiotic timing for 83%, supplemental antibiotic dosing for 34%, and antibiotic duration of less than 24 h for 44%. Normothermia was present in 79% of surgeries, and normoglycemia was present in 17%. Univariate analysis of the SSI rate identified four significant factors. Antibiotic prophylaxis for less than 24 h postoperatively (odds ratio [OR], 0.213; 95% confidence interval [95% CI]0.060 to 0.757) and neurosurgery (OR, 0.118; 95% CI, 0.15 to 0.903) correlated with a reduced risk of SSI. The mean number of prophylaxis errors (OR, 1.6; 95% CI, 1.02 to 2.4) and a duration of surgical drainage for more than 3 days (OR, 2.679; 95% CI, 1.009 to 7.113) predicted SSI. By multivariate analysis, errors in individual antibiotic prophylaxis measures were not significantly associated with SSI; however, the presence of more than two errors was significant (OR, 4.030; 95% CI, 1.018 to 15.96). A strong correlation was identified between the degree of concordance to SSI prevention guidelines and the SSI rate (P = 0.001, Mantel-Haenszel linear-by-linear association chi-square test).     

Supplemental perioperative oxygen for reducing surgical site infection: a meta-analysis

Objective  To assess the efficacy of supplemental perioperative oxygenation for prevention of surgical site infection (SSI).
Data sources  Computerized PUBMED and MEDLINE search supplemented by manual searches for relevant articles.
Study selection  Randomized, controlled trials evaluating efficacy of supplemental perioperative oxygenation versus standard care for prevention of SSI in patients' undergoing colorectal surgery.
Data synthesis  Data on incidence of SSI were abstracted as dichotomous variables. Pooled estimates of the relative risk (RR) and 95% confidence interval (CI) were obtained using the DerSimonian and Laird random effects model and the Mantel-Haenzel fixed effects model. Heterogeneity was assessed using the Cochran Q statistic and I².
Results  Four randomized controlled trials met the inclusion criteria. Supplemental perioperative oxygenation resulted in a reduced incidence of SSI [RR 0.70 (95% CI 0.52–0.94), P  = 0.01], using a fixed effects model. Using the more conservative random effects model, the point estimate was similar [RR 0.74 (95% CI 0.39–1.43), P  = 0.37], but the results failed to achieve statistical significance. The I² test showed moderate heterogeneity.
Conclusions  Our analysis showed that supplemental perioperative oxygenation is beneficial in preventing SSI in patients undergoing colorectal surgery. Because of heterogeneity in study design and patient population, additional randomized trials are needed to determine whether this confers benefit in all patient populations undergoing other types of surgery. Supplemental perioperative oxygenation is a low-cost intervention that we recommend be implemented in patients undergoing colorectal surgery pending the results of further studies. Further research is needed to determine whether or not supplemental hyperoxia may cause unanticipated adverse effects.

A single-dose regimen for antimicrobial prophylaxis to prevent perioperative infection in urological clean and clean-contaminated surgery

A single dose of antimicrobial prophylaxis (AMP) was administered parenterally for the prevention of perioperative infection in a total of 788 patients undergoing urological surgery, including 380 endoscopic-instrumental, 328 clean, and 80 clean-contaminated operations performed at our institute between January 2007 and December 2009. Surgical site infections (SSIs), urinary tract infections (UTIs), and remote infections (RIs) were prospectively surveyed. The definition for a single dose of AMP allowed for the administration of an additional dose of an antimicrobial during surgery if the procedure was longer than 3 h, but not for the parenteral or oral administration at the end of the procedure in the recovery room, or at a later time over a period of more than 24 h. UTI was observed in 12 (3.2%) patients after endoscopic-instrumental operation, 1 (0.3%) after clean operation, and 1 (0.9%) after clean-contaminated operation. SSI was observed in 2 (0.6%) patients after clean operation but in none after clean-contaminated operations. RI was observed in 1 (0.3%) patient after endoscopic-instrumental operation, 3 (0.9%) after clean operation, and none after clean-contaminated operations. A single-dose regimen of AMP was effective and feasible for the prevention of perioperative infections, including SSIs, UTIs, and RIs, in endoscopic-instrumental, clean, and clean-contaminated urological surgical procedures.     

Impact of the practical guideline on appropriate usage of antimicrobial treatments for surgical site infections in reconstructive surgery of head and neck cancer

ObjectivesIn 2016, Japanese Society of Chemotherapy and Japan Society for Surgical Infection presented the practical guideline for appropriate usage of antimicrobial agents to prevent postoperative infections. This study aims to exhibit the validity of the guideline as a series of effective strategies for prevention of surgical site infections (SSIs) during reconstructive surgery of the head and neck cancer.MethodsWe retrospectively evaluated patients who underwent head and neck reconstructive surgery with free or pedicle flaps in a single institute in Japan between July 2010 and July 2020. We evaluated the incidence of SSIs, patient backgrounds, and microbiological characteristics on the basis of antimicrobial prophylaxis recommended by the guideline.ResultsEnrolled in this study were 102 patients in our institution who underwent head and neck reconstructive surgery with free or pedicle flaps between July 2010 and July 2020. In the period between January 2018 to July 2020 after the SSI guideline was advocated (SSI guideline period), the ratio of administration of sulbactam/ampicillin (SBT/ABPC) was significantly higher (P < 0.001) and the duration of prophylactic antimicrobial treatment was significantly shorter than in the period between July 2010 to December 2017 before the SSI guideline was advocated (Pre-SSI guideline period) (P < 0.001). Incidence of SSIs were similar, even when antibiotic use was changed to be short-term single-agent administration in accordance with the practical guideline.ConclusionsAdherence to the current Japanese practical guideline on appropriate antimicrobial prophylaxis for SSIs can shorten the duration of usage of antimicrobial treatment without increasing the risk for occurrence of SSIs.     

Post-discharge surveillance and its impact on surgical site infection incidence

Because of their high incidence and associated repercussions, Surgical Site Infections (SSI) are an important problem among hospital-acquired infections. The aim of this study was to determine the incidence of SSIs in patients submitted to morbid obesity and gastric surgeries for other causes during the hospitalization and post-discharge periods. In this survey, conducted in two teaching hospitals in the city of S?o Paulo between August of 2001 and March of 2002, in accordance to the NISS methodology, 158 patients were followed - 81 had been submitted to morbid obesity surgeries and 77 to gastric surgeries for other causes. In 64 cases there occurred SSI, of which 6.3% during hospitalization and 34.1% after discharge. During hospitalization, the incidence of SSI was 5% in the morbid obesity surgeries group and 7.8% in the gastric surgeries for other causes group; in the post-discharge period, the figures increased to 55.5% and 24.7% respectively. These results confirm the importance of following surgical patients after discharge and demonstrate that post-discharge surveillance is an important tool for obtaining dependable data and redirect SSI's prevention and control policies.     

Surgical-site infection surveillance at a small-scale community hospital

Surveillance of surgical-site infection (SSI) is becoming more important given the current situation of increasing antibiotic resistance by microorganisms. It may be difficult to carry out SSI surveillance at small-scale community hospitals because of small staff numbers. We examined whether SSI surveillance could be carried out with a system we devised. Furthermore, we investigated the SSI rateat our small-scale community hospital (179 beds) in aJapanese city (populations, 330 000). Between June andDecember 2003, operations were performed on 210patients. Procedures were identified as clean (n = 85),clean-contaminated (n = 108), contaminated (n = 14), or dirty-infected (n = 3). A 7-month prospective survey ofSSI was conducted. SSIs were classified according to the Centers for Disease Control and Prevention criteria and identified using bedside surveillance and post-discharge follow-up. SSI developed following 16 procedures (7.6%). All patients who developed SSI had received antibiotic prophylaxis. Among the 16 patients with SSI, operations were clean (n = 1), clean-contaminated (n = 8), contaminated(n = 5), or dirty-infected (n = 2). Enterobacteriaceae were the most frequently isolated microorganisms, followed by Pseudomonas aeruginosa. SSI surveillance is just as important at small community hospitals as it is at larger hospitals, and SSI surveillance is relatively simple to institute at small-scale community hospitals with the selective use of investigation items.
