Correlation of Hoarseness Fallowing Tracheal Intubation with Some of the Demographic and Clinical Characteristics of Patients Undergoing Surgery

Hoarseness is a common complication after tracheal intubation. The aim of this study was to investigate the correlation between hoarseness after tracheal intubation with some demographic and clinical characteristics of patients undergoing elective surgery in Alzahra hospital, Isfahan, Iran.
This descriptive-prospective analytic study conducted on 98 patients (mean age: 38.7 ± 13.4 years, gender: 53.2% were women) undergoing elective surgery and had eligible criteria for the study. The correlations between intubation complication (hoarseness) and some demographic data [sex, age, weight, height, and body mass index (BMI)] and clinical characteristics (duration intubation, type of surgery, and tube size) were studied. Data were collected 72 hours after the surgery and analyzed using SPSS software.
Findings: In this study, 98 patients with a mean intubation time of 165.5 minutes were studied. Straining during extubation (55.1%), hoarseness (25.5 %), cough (7.1%), and sore throat (7.1%) were prevalent intubation complications, respectively. The correlations between duration of intubation (P = 0.027), and type of surgery (P = 0.040) with hoarseness were statistically significant. But there was not significant correlation between age, height, weight, tracheal tube size, and body mass index with hoarseness (P ≥ 0.050).
The results indicate significant correlation between hoarseness and duration of intubation and type of surgery.
