Haemodynamic response at double lumen bronchial tube placement - Airtraq vs. MacIntosh laryngoscope, a randomised controlled trial
INTRODUCTION: Tracheal intubation causes a haemodynamic response that might be harmful for patients. The Airtraq® laryngoscope has been shown to decrease the haemodynamic response to single-lumen tube intubation. We hypothesised that double-lumen bronchial tube placement with the Double-lumen Airtra...

description | INTRODUCTION: Tracheal intubation causes a haemodynamic response that might be harmful for patients. The Airtraq® laryngoscope has been shown to decrease the haemodynamic response to single-lumen tube intubation. We hypothesised that double-lumen bronchial tube placement with the Double-lumen Airtraq® laryngoscope would cause a reduced haemodynamic response and decreased catecholamine release compared with the MacIntosh laryngoscope. METHODS: Forty adult patients were randomly assigned to the Airtraq® group or to the MacIntosh group. Intubation with either the Airtraq® or the MacIntosh laryngoscope was performed two minutes after standardised induction of anaesthesia. Arterial blood pressure, heart rate, catecholamine levels, bispectral index and duration of the intubation procedure were measured. RESULTS: Mean (standard deviation [95% confidence interval]) systolic arterial blood pressure at laryngoscopy with the Airtraq® laryngoscope was 124 (34 [106 to 141]) mmHg and, with the MacIntosh laryngoscope, it was 110 (25 [99 to 122]) mmHg (p=1.0). Heart rate at laryngoscopy with the Airtraq® laryngoscope was 75 beats·min-1 (16 [67 to 83]) and, with the MacIntosh laryngoscope, it was 64 beats·min-1 (14 [58 to 71]) (p=0.71). Adrenaline levels post-intubation were 54.3 ng·l-1 (41.5) [29.3 to 79.4] in the Airtraq® group and 30.5 ng·l-1 (25.6) [15.1 to 46.0] in the MacIntosh group (p=0.016). The duration of intubation with the Airtraq® laryngoscope was 88 s (31 [72-104]) while, with the MacIntosh laryngoscope, the duration was 75 s (35 [59-92]) (p=0.26). CONCLUSIONS: The use of the Double-lumen Airtraq® laryngoscope provides no benefit regarding stress response compared to the MacIntosh laryngoscope. |
