Surgical asepsis

Robert Lawson Tait was an original thinker, a surgical innovator, a controversialist and an iconoclast. He made important contributions to surgery, was an eloquent supporter of Darwinian evolution and women in medicine and opposed vivisection. He is probably best remembered for his high-profile opposition to Listerian antisepsis which continued until his death. While Lister went on to receive the country's highest honours and was lauded throughout the world, Tait received much more modest honours and little subsequent recognition by historians...

Health care-associated infections (HAI) directly influence the survival of children in pediatric intensive care units (PICU), the most common being central line-associated bloodstream infection (CLABSI) 25-30%, followed by ventilator-associated pneumonia (VAP) 20-25%, and others such as catheter-associated urinary tract infection (CAUTI) 15%, surgical site infection (SSI) 11%. HAIs complicate the course of the disease, especially the critical one, thereby increasing the mortality, morbidity, length of hospital stay, and cost...

BACKGROUND: Basic surgical skills (BSS) is a key bridging course for medical students to acquire basic surgical maneuvers and practice animal surgery before clinical rotation, but the complexity of operational procedures and high demands on asepsis may lead to poor performance and frequent error during practice. The current study intended to improve BSS teaching outcomes by implementing smartphone app-based competency and performance checklists for medical academy undergraduates. METHODS: WeChat-based checklists containing competency and performance modules were designed, distributed and collected via smartphone...

In the operating theatre, the scrub nurse has a wide range of roles, including responsibility for organising and ensuring that the correct instrumentation is available to the surgeon in the operating field, while maintaining stringent adherence to the principles of asepsis. Robotic techniques have revolutionised many procedures, providing surgeons with improved tissue access and tool control compared with open or laparoscopic techniques. However, adopting this technology has created additional challenges in the scrub nurse's role in areas such as team dynamics and the need to gather and disseminate vital patient information...

In the 18th century, anatomy was the principal science underlying surgical practice. Over the next three centuries, the scientific basis of surgery changed dramatically. Morbid anatomy led to the understanding of organ-based pathologies that allowed surgeons to remove, reconstruct and in some cases replace internal organs. In the 19th century, the new science of microbiology facilitated antisepsis, then asepsis as surgery progressed from a craft to a scientific discipline. Yet many surgeons believed that surgery was not merely a science but also an art, in which the creativity of the doctor was necessary for progress...

Ensuring asepsis of the surgical site before surgery is an essential component of safe surgical practices to reduce the incidence of surgical site infections in veterinary medicine. The current accepted method of skin preparation is a multistep process that alternates either a povidone-iodine or chlorhexidine soap scrub with a 70% alcohol rinse. After cleansing, the site is left to dry before draping. The goal of this study was to assess the effectiveness of a waterless alcohol-based (WAB) antiseptic as part of a 2-step procedure after the soap scrub...

BACKGROUND: Nurses' working conditions are important for their well-being at work and for their ability to provide patients with safe care. Self-efficacy can influence employees' behaviour at work. Therefore, it is valuable to study self-efficacy levels to medical asepsis in relation to working conditions. OBJECTIVE: To investigate the relationship between nurses assessed self-efficacy levels to medical asepsis in care situations and structural empowerment, work engagement and work-related stress...

Background: Millions of patients admitted globally in health care setups require insertion of peripheral intravascular catheter for intravenous drugs or fluid administration. However, if proper precautions are not followed during insertion, it results in significant morbidity. This study was designed to study the efficacy and safety of recommended Centre for Disease Control and Prevention (CDC) guidelines for peripheral intravascular catheter insertion practice and its comparison with a standard insertion protocol being followed and their outcome...

Telemetric monitoring is used in many scientific fields, such as cardiovascular research, neurology, endocrinology, as well as animal welfare research. Nowadays, implanted electrocardiogram (ECG) radiotelemetry units are the gold standard for monitoring ECG traces, heart rate and heart rate variability in freely moving mice. Telemetry technology can be a valuable tool when studies utilize it adequately, while prioritizing animal welfare. Recently, concerns have been raised in many research fields, including animal research, regarding the reproducibility of research findings, with insufficient reporting being one of the underlying causes...

Gustav Adolf Neuber was a celebrated multifaceted German surgeon, who significantly contributed to the establishment of modern surgical Antisepsis techniques as well as the modification and questioning of the use of wound drainage systems. In addition, he reformed architectural and structural concepts regrading operating rooms. In the field of plastic surgery, Gustav Adolf Neuber established a procedure for autologous fat-grafting. The lack and inadequacy of literature sources regarding Neuber´s contribution to common surgical practices and antisepsis vastly disregards the importance of his work...

Aim: The aim of the current study was to assess the clinical success of immediate loading implant in the esthetic zone. Materials and Methods: 20 patients with 20 teeth to get replaced were selected for the study. All patients underwent a pre-surgical preparation followed by draping. Following stringent asepsis, necessary precaution was taken to not to injure the socket wall while removal of tooth. After removal, socket was thoroughly cleaned and curetted with saline and betadine...

Backgrounds: Postoperative wound complication is a major risk factor for the development of Periprosthetic joint infection. We innovatively invented a new dressing system to reduce the occurrence of postoperative wound complications and improve the quality of life of patients after total hip arthroplasty. Methods: A total of 120 patients who underwent primary unilateral total hip arthroplasty were enrolled in this study. The data collected included the number of dressing changes, costs of the dressings, postoperative hospital stay, The Visual Analogue Scale (VAS) score, The Harris Hip Score (HHS), ASEPSIS score, The Stony Brook Scar Evaluation Scale (SBSES), wound complications, the frequency of showers and satisfaction...

PURPOSE: The goal was to evaluate the advent of surgical gloves during the eighteenth century, nineteenth century, and the beginning of the twentieth century. MATERIAL AND METHODS: We used first drawings and paintings, then historical photographs identified in books after 1830 (date of discovery of the photography) or in medical reports of surgery and anesthesiologists. The pictures determined the presence or absence of gloves in the period corresponding to the changing understanding of aseptic and antiseptic techniques proposed by Lister and Pasteur...

Background: The present study aims to evaluate how the measures to contain the SARS-CoV-2 spreading affected the surgical site infections (SSIs) rate in patients who underwent nondeferrable breast cancer surgery (BCS). Methods: This study is a retrospective analysis of prospectively collected data from a consecutive series of patients underwent nondeferrable BCS in a regional Italian Covid-free hub during two different period: March to April 2020 (pandemic cohort [PC]) and March till April 2019 (control cohort [CC])...

BACKGROUND: Wound infection represents a frequent trouble following open saphenous vein harvesting in cardiac surgery. Platelets' growth factors are crucial for the healing process. Prophylactic platelet rich plasma (PRP) application on leg wound might reduce the incidence of saphenous vein harvest site infections in patients undergoing coronary artery bypass graft surgery (CABG). METHODS: Between January 2009 and December 2020, 987 consecutive patients underwent CABG using saphenous vein as conduit graft and were retrospectively divided into two groups...

BACKGROUND: Antibiotic resistance is a global problem. Irrational use of antibiotics is rampant. Guidelines recommend administration of single dose of antibiotic for surgical antimicrobial prophylaxis (SSAP) for elective obstetrical and gynaecological surgeries. However, it is not usually adhered to in practice. Majority of women undergoing elective major gynaecological surgeries and caesarean sections in the department of obstetrics and gynaecology of our tertiary level heavy case load public health facility were receiving therapeutic antibiotics (for 7-10 days) instead of recommended SSAP...

OBJECTIVE: To provide a systematic assessment of the efficacy of preoperative skin asepsis using chlorhexidine versus povidone-iodine based protocols for surgical site infection (SSI) prevention in veterinary surgery. STUDY DESIGN: Systematic meta-analytical review according to PRISMA-P guidelines. SAMPLE POPULATION: Studies comparing preoperative skin asepsis protocols using chlorhexidine versus povidone-iodine in veterinary surgery identified by systematic search between 1990 and 2020...

BACKGROUND: It is well recognised that medical students need to acquire certain procedural skills during their medical training, however, agreement on the level and acquisition of competency to be achieved in these skills is under debate. Further, the maintenance of competency of procedural skills across medical curricula is often not considered. The purpose of this study was to identify core procedural skills competencies for Australian medical students and to establish the importance of the maintenance of such skills...

There is no clear recommendation for wound closure material in foot and ankle surgery. Thus, we hypothesized that there was no difference in clinical outcomes among 3 suture materials, namely, absorbable sutures, nonabsorbable sutures, and metallic staples. This study compared the 3 materials for wound closure in foot and ankle surgery. In this prospective randomized study, 124 patients were randomly divided into the nonabsorbable suture group, absorbable suture group, and staple group. ASEPSIS score, Hollander Wound Evaluation Scale, and numerical rating scale (regarding pain and satisfaction) were collected at first dressing changes, suture removal, and 6 weeks after surgery...

BACKGROUND: Lower limb amputation (LLA) is typically described as 'clean surgery', but surgical-site infection (SSI) rates are high and there is significant variation in antibiotic prophylaxis practice. This study aimed to determine whether an extended period of antibiotic prophylaxis (5-day course) is superior to a short course (24 h) in preventing SSI in patients undergoing minor and major LLA. METHODS: Patients undergoing minor and major amputation from a single vascular unit were recruited and randomized to receive either a 5-day or a 24-h prophylactic course of antibiotics...
