Abstract:
Objective To explore the effect of flexible laser endotracheal intubation optical device (patent number 201520785723.7) on oral and maxillofacial intubation operations. Methods Forty-two patients with the oral and maxillofacial intubation optical device for general anesthesia were included in this study. The patients were from 16 to 73 years old and ASAⅠ-Ⅱ. Surface anesthesia was prepared for airway and nasal cavity. There were 27 patients whose mouth opening were smaller than 3 cm. After intravenous injection of midazolam 0.05 mg/kg and sufentanil 0.2μg/kg, reinforced endotracheal tube was inserted into throat 13-15 cm, then the probe shape to 120° and optical device were placed into the tube respectively, guided the tube according to the light spot in front of neck. There were 15 patients whose mouth opening were not smaller than 3 cm. The quick guidance optical device and larygoscope were adopted to help the intubation. After intravenous injection of midazolam 0.05 mg/kg, sufentanil 0.5 μg/kg, propofol 2 mg/kg, cisatracurium 0.2 mg/kg, the reinforced endotracheal tube was inserted into the oral cavity nasally, and completed intubation with laryngoscope. The success rate of intubation, time of intubation, the real-time blood pressure before and after intubation, heart rate and related complications were recorded before intubation and after intubation. Results In the 42 patients, 41 patients were successful for guidance intubation, and the success rate of intubation was about 97.6%. The average intubation time was(124.5±38.2) seconds. The shortest intubation time was 12 seconds and the longest was 276 seconds. During intubation, the increases of blood pressure and heart rate were in the normal range (<30%). Levels of SpO2 were maintained at 0.92-1.00. All the patients were without agitation. There were no serious complications such as hoarseness and pharyngalgia after operation.Conclusion The flexible laser endotracheal intubation optical device can be used quickly for oral and maxillofacial intubation, and the 45° bevel design for optical device can form two kinds of zones with bright light upward and downward. It is a new tool for nasal intubation that is more convenient for location of light guidance, and has high success rate and small stimulation.
