Abstract:
Introduction. Nosocomial infections (NIs), also referred to as healthcare-associated infections
(HAIs), are presently a major concern in surgical practice. The rates of nosocomial infections serve
as a crucial indicator of the quality of healthcare provision in surgical units. Hence, examining the
incidence of NIs and identifying the pathogens more frequently associated with them contributes
to a deeper understanding of this issue.
Aim of study. To review articles that addressed nosocomial infections in surgical practice.
Methods and materials. A review of relevant articles was conducted on the incidence of
nosocomial infections and pathogenic agents within surgical units.
Results. A recent study (Olof Jannach et al., 2015) revealed that among 358 patients, of which
42% with pancreatic resection, 25% cases with hepatic resection 29%—gastric resection (3%), and
esophageal resection—33.5% patients developed one or more surgical site infections (SSIs). The
most prevalent were intra-abdominal septic infections (16.5%) and postoperative surgical wound
infections (12.3%). The main causative agents were E. coli (12.4%), coagulase-negative
staphylococci (12.2%), and Enterococcus faecium (9.7%). According to other authors
(Wondemagegn Mulu et al., 2012), the incidence of surgical site infections in aseptic and
contaminated operations was 3.3% and 12.8%, respectively. A total of 42 bacterial pathogens were
identified, with Staphylococcus aureus being the predominant strain in 26.2% cases, followed by
E. coli and coagulase-negative Staphylococcus species, making up 21.4%. About 100% of Grampositive bacterial isolates and 95.5% of Gram-negative isolates exhibited resistance to two or more
antimicrobial drugs. In the study conducted by (N. Capsamun,2013), focusing on the pediatric
neurosurgery unit as a model, it was found that the incidence of nosocomial infections (NIs) is
directly correlated with the length of surgical interventions. Specifically, patients with a surgery
duration of 0-1 hour had a NI incidence of 2.12%, those who underwent surgery for 2-3 hours
showed- 12.76%, and patients with a surgery duration of 3-4 hours or more had the highest
incidence of 44.68%.
Conclusion. NIs pose a significant medical and social challenge due to their increased incidence,
diverse etiological factors, and high resistance of causative agents to antimicrobial drugs.
