Abstract: Objective　To explore the current management status of negative pressure sinus irrigation technology in Guangdong Province and provide a basis for formulating and promoting relevant technical standards. Methods　A cross-sectional survey was conducted from February to March 2024 using convenience sampling.Participants included 44 head nurses or nursing backbone from 44 hospitals in 21 prefecture-level cities in Guangdong Province were selected as the study subjects,all of whom were female,with a weighted average age of 39.95 years. Among them, 40 were from tertiary hospitals, 3 from secondary hospitals, and 1 from a specialized hospital; 10 were nurse practitioners, 28 were nurse supervisor, 5 were associate chief nurses, and 1 was a chief nurse practitioner; working years: 12 had 5≤ years <10, 23 had 10≤ years <20, and 9 had years ≥20. Data were collected via a self-designed questionnaire assessing negative pressure sinus displacement technique practices. Results　44 questionnaires were returned. (1) Related knowledge mastery : 28 (63.64%) mastered the operation indications of sinus negative pressure replacement technology, 10 (22.73%) mastered the contraindications, and 13 (29.55%) mastered the operation complications. (2) Procedure management:26 hospitals (59.09%) used mucosal contraction agents, 29 hospitals (65.91%) used syringe drip diluent, and 40 hospitals (90.91%) used normal saline as drip solution. 31 hospitals (70.45%) used negative pressure below 0.024 Mpa for suction, and 42 hospitals (95.45%) used pillow-supported supine position.(3) Procedural training management:All 44 hospitals (100%) had qualified access requirements for negative pressure sinus displacement technique , and 42 hospitals (95.45%) had strict operation training programs. Conclusion　Nurses in Guangdong Province's otorhinolaryngology departments demonstrated suboptimal knowledge regarding negative pressure sinus displacement technique ,procedural management requires standardization.It is recommended that professional associations establish evidence-based practice guidelines for negative pressure sinus displacement technique ,individual hospitals should enhance operator training and management.
