| Popis: | Objective To evaluate the extraction force generated at different extubation angles using a manikin simulation and a randomized clinical trial. Methods Simulations were performed on a manikin to assess the force generated at extubation angles of 0°, 30°, 45°, 60°, 90° and 120° relative to the ground. The trial compared extraction force and changes in vital signs in patients undergoing general anaesthesia with tracheal intubation followed by extubation at 60° or 90°. Results The simulation study found that the extubation force was significantly lower at 45° and 60° than at all other extraction angles. In the trial, extubation at 60° resulted in significantly lower extraction force and systolic blood pressure elevation ( n = 23) than extubation at 90° ( n = 23). Conclusion Findings in a manikin simulation were confirmed by those of a randomized clinical trial, where extubation at 60 ° required less force than 90 °, and was accompanied by less SBP elevation. Extubation at 60 ° is less invasive than extubation at 90 °. |
