Hoarseness is a common complication after tracheal intubation and prolonged hoarseness may be very limiting for a patient. This study was designed to examine the duration of hoarseness after tracheal intubation and to identify risk factors that may increase the duration of hoarseness. ⋯ The age of the patient and duration of intubation were significant factors in the duration of hoarseness after tracheal intubation. In addition, the incidence of arytenoid cartilage dislocation was 0.097%.

Randomized Controlled Trial Comparative Study
Analgesic effectiveness of ropivacaine 0.2% vs 0.4% via an ultrasound-guided C5-6 root/superior trunk perineural ambulatory catheter.
In this prospective, randomized, triple-blinded study, we tested the hypothesis that a 48 h continuous C5-6 root/superior trunk patient-controlled infusion of ropivacaine 0.4% would provide superior analgesia after shoulder surgery compared with the same infusion of ropivacaine 0.2%. ⋯ After major shoulder surgery, ropivacaine 0.2% at 2 ml h(-1) with on-demand 5 ml boluses administered via an ultrasound-guided C5-6 root/superior trunk perineural catheter produces similar analgesia, but higher patient satisfaction compared with ropivacaine 0.4%.
