High Flow Nasal Cannula Oxygen During Sedation for Video-assisted Thoracoscopic Surgery

Preventing Deoxygenation With High Flow Nasal Cannula Oxygen During Sedation for Video-assisted Thoracoscopic Surgery: A Randomized Controlled Trial


Lead Sponsor: Alexandria University

Source Alexandria University
Brief Summary

High-flow nasal cannula (HFNC) is a device that delivers10 to 70 L min-1 of heated, humidified 100% oxygen via nasal route. It provides positive airway pressure, decreases dyspnea, decreases the work of breathing, and improves comfort

Detailed Description

Beneficial effects of the HFNC system have been assessed based on 3 physiologic conditions: decreased dead space, a high concentration of inspiratory oxygen, and positive pressure in the oro-laryngeal cavity.Studies have shown that it improves oxygenation in various perioperative settings such as the apneic patients, patients with respiratory failure , and patients undergoing bronchoscopy

Label: HFNC group

Type: Active Comparator

Description: For HFNC group, F&P AIRVOTM 2 will be adjusted to give the patients the oxygen flow at 50L/min and the FiO2 at 1.0.Then after three minutes of preoxygenation, sedation will be conducted by giving 25 µg fentanyl and a bolus of 1 mg/kg propofol followed by continuous infusion of propofol using a target-controlled infusion system (TCI pump TE371; Terumo Corporation, TokyoJapan).

Label: control group

Type: Placebo Comparator

Description: induction of general anaesthesia will be done using 2 mg/kg propofol and 1 µg/kg fentanyl. Double lumen tube will be facilitated by cisatracurium 0.2 mg/kg. Anaesthesia will be maintained with isoflurane 0.8 %-1% in 100% oxygen and maintenance dose of cisatracurium 0.02 mg/kg when needed. At the end of surgery, residual neuromuscular paralysis will be antagonized with neostigmine 0.05 mg/kg and atropine 0.01 mg/kg.
