Clinical Trial Summary
Postoperative sore throat is a complication of orotracheal intubation. The aim of our study
was to assess the impact of videolaryngoscopy on postoperative sore throat during the first
24 hours following surgery.
This was a prospective, randomized study, over a period of 9 months. The investigators
included 136 patients with non-difficult airway, classified ASA I to III and over 18 years
old. The patients were randomized into 2 groups: the VL group including 70 patients intubated
with direct laryngoscopy and the LD group including 66 patients intubated with
videolaryngoscopy.
Description:
The investigators monitored blood pressure, ECG, saturation in oxygen, capnograph,
temperature and curarization. They also monitored cuff pressure using manometer.
The investigators pre-oxygenated the patients until the fractional expired oxygen was over
90%, then induced anaesthesia using either 2.5 to 3.5 mg/kg of propofol or 0.3 to 0.4 mg/kg
of etomidate, then 1mg/kg of suxamethonium (in absence of contraindication). If modified
crash induction was performed, the anaesthesiologist mentioned the opioid used.
The investigators performed laryngoscopy using either a Macintosh laryngoscope using a number
4 blade in LD group, or a McGrath video-laryngoscope with a number 4 blade in VL group and a
stylet when needed. Women were intubated using number 7 tube and man using a 7.5 tube. They
inflated the cuff with 7ml of air, and controlled pressure by manometer every 30 minutes in
order to maintain it between 20 and 25 mmHg.
The investigators ventilated patients with assisted controlled mode using a 6ml/kg of ideal
weight volume, a 6 mmHg PEEP, a 50% inspired fraction of oxygen and a respiratory rate
guaranteeing an end-expiratory CO2 level between 35 and 40 mmHg. Then, they administrated 4
mg of Ondansetran in order to prevent postoperative nausea and vomiting (PONV).
The investigators maintained anaesthesia using either isoflurane or sevoflurane, 0.1 μg/kg of
sufentanil and 0.05 mg/kg of atracurium.
