Patients’ perception of sound levels in the surgical suite

摘要: Abstract Study Objectives: To measure sound levels that our patients are exposed to in the surgical suite and their perception of these levels. Design: Sound experienced by 100 undergoing general anesthesia for elective surgery during three phases: induction maintenance operating room (OR), recovery from room, were measured using a Type 4436 Noise Dose Meter. The equivalent continuous (Leq), maximum (Lmax), sources sounds noted. Patients interviewed 24 hours after about they had OR rooms. Measurements Main Results: Leq induction, maintenance, phases 70.3 ± 16.8 dB(A), 66.2 4.1 dB(A) 71.8 6.1 respectively. These much higher than international recommendations hospital acute care areas exceed thresholds produce noise-induced cardiovascular endocrine effects. significantly compared phase. Thirty-two found phase noisy 33 noisy. distressed 16 52 would have preferred quieter environment. There was no difference those who expressed dissatisfaction with did not. Much noise, particularly staff conversations, unnecessary alarms, preparation equipment, could been prevented simple measures. Conclusion: prevention needs more attention should be routine part patient care.
