Bonfls intubation fberscope versus C-MAC videolaryngoscope - hemodynamic stability and incidence of sore throat in endotracheal intubated patients

Introduction: Hemodynamic stability at laryngoscopic intubation is infuenced by mechanical stimuli on the afected area of the oropharynx. The use of appropriate tools can lower mechanical stimuli and lead to a better outcome. The purpose of this study was to determine whether the use of Bonfls intubation fberscope provided a better hemodynamic stability, and decreased the incidence of a sore throat compared to Macintosh videolaryngoscope. Materials and Methods: We conducted a non-blind randomized controlled trial. It was conducted at Sanglah Hospital, Indonesia, in September to October 2016 with a sample of 50 people. The sample was divided into two groups. The patients were induced by propofol TCI target efect 4 µg/ml and analgesia with fentanyl 2 mcg/kg. Hemodynamic conditions assessed since the induction, one minute before intubation, and one minute, three minutes, and fve minutes after laryngoscopy intubation. A sore throat was evaluated before and after treatment. Results: The MAP value and pulse rate in one minute and three minutes after laryngoscopy intubation in CMAC group were signifcantly higher compared to Bonfls group (p<0.001). The proportion of a postoperative sore throat is signifcantly diferent between the two groups (p=0.042). Conclusion: Bonfls intubation fberscope proved better in providing hemodynamic stability and decreased the incidence of a sore throat compared to Macintosh videolaryngoscope in patients underwent general anesthesia.
