[Transient low frequency hearing loss following spinal anesthesia]

Area of Science:

• Otolaryngology
• Anesthesiology
• Neurosurgery

Context:

• Spinal anesthesia is a common procedure for urological operations.
• Hearing loss is a rare complication following spinal anesthesia.
• Previous literature has limited reports on this specific adverse event.

Purpose:

• To prospectively investigate the incidence and characteristics of hearing loss after spinal anesthesia.
• To determine if hearing disturbances are a common or rare occurrence in patients undergoing urological procedures under spinal anesthesia.
• To document the reversibility and required treatment for post-spinal anesthesia hearing loss.

Summary:

• A prospective study of 100 patients undergoing urological operations with spinal anesthesia was conducted.
• Three patients (3%) presented with transient, low-frequency (30 dB) hearing loss.
• The hearing disturbance was reversible and did not require specific therapeutic intervention.

Impact:

• Highlights a rare but documented complication of spinal anesthesia.
• Informs clinicians about the potential for transient hearing loss.
• Suggests that careful monitoring may be sufficient for managing this auditory disturbance.
