Abstract:
Objective To explore the influence of the iodine disinfection on nasal bacterial colonization through the transsphenoidal approach. Methods Totally 133 pituitary adenoma patients who underwent transsphenoidal surgery in our department from January to August 2017 were enrolled in this study. Before disinfection,pharyngeal swabs of inferior turbinate root secretions were taken for bacterial culture. After iodine disinfection,pharyngeal swabs were taken again at the same site. Changes in the nasal bacterial spectrum before and after disinfection were compared. Patients were followed up for three months after the surgery,during which any intracranial infection/bacteraemia was recorded,and its correlation with nasal bacteria colonization was analyzed. Results Nasal bacterial colonization was detected in 45 (33.8%) of 133 patients before iodine disinfection and in only 6 cases (4.5%) after iodine disinfection (χ=34.5,P=0.000). Thus,iodine disinfection eliminated 86.7%(39/45) of the colonized bacteria. The most common nasal bacterium was Staphylococcus aureus (24.4%,11/45),followed by Klebsiella pneumoniae (24.4%,11/45),and Staphylococcus epidermidis (13.3%,6/45). One patient had high fever and chills 2 days after surgery,but blood culture and cerebrospinal fluid culture showed negative Results . After the administration of third-generation cephalosporins,the symptoms disappeared after two days. Conclusion sThere are colonized bacteria in nasal cavity. Iodine disinfection of nasal cavity can effectively clear most of the nasal bacteria. The possibility of intracranial infection/bacteremia after transsphenoidal approach is low.
