Anterior servikal omurga cerrahisi sonrası farklı endotrakeal tüp kaf basınçlarının disfajı üzerine etkileri

Abstract

of two different endotracheal cuff pressures on postoperative dysphagia, sore throat, dysphonia, and hospital stay in anterior cervical spine surgery.
 Materials and Methods: Seventy patients scheduled for surgery were randomly divided into two groups. After intubation, the endotracheal cuff pressure was inflated to 20 cmH2O and 25 cmH2O in Group I (n=35) and Group II (n=35), respectively. The degree of dysphagia was assessed with the Bazaz dysphagia score. The sore throat was evaluated via Visual Analog Scale. Total pain score regarding the operation site was evaluated using VAS. Hoarseness was evaluated based on the presence of any changes to the voice asharsh or strained. Dysphagia, dysphonia, and sore throat were assessed on the post-surgical 1st and 24th hours. 
 Results: No differences in demographic data were present between the groups. Dysphagia and sore throat at the post-surgical 1st and 24th hours were significantly lesser in Group I than in Group II. The frequency of dysphonia was significantly less in Group I than compared to Group II only at the post-surgical 1st hour. No differences in VAS scores at the post-surgical 1st and 24th hours were present between the groups. 
 Conclusion: In this study, it was shown that the risk of developing dysphagia after surgery was significantly reduced with 20 cmH2O endotracheal cuff pressure compared to 25 cmH2O. Also, lower cuff pressure was associated with a milder sore throat, less hoarseness at 1 hour postoperatively, and a shorter hospital stay.
