Objective: To discuss the clinical application of superior laryngeal nerve block combined with thyrocricocentesis Tracheal Surface Anesthesia (TSA) in emergency tracheal cannulation for cerebral trauma.
Methods: A total of 62 patients who were treated with emergency tracheal cannulation for cerebral trauma in our hospital from Dec 2014-2016 were selected randomly as research subjects. They were divided into the control and test groups according to the method of achieving anesthesia. Variations in associated indexes after anesthesia were compared to evaluate the anesthetic effect.
Results: The test and control groups show no significant differences in Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure (MAP) and Heart Rate (HR) at different periods (P>0.05). In the test group, the SBP, DBP, and MAP significantly decrease, whereas the HR significantly increases 10 min after the anesthesia (P<0.05). In the control group, the SBP, DBP, and MAP decrease, whereas the HR increases. However, the difference is not statistically significant (P>0.05). The test group consumes significantly shorter time for tracheal cannulation after anesthesia and receives better oxyhemoglobin saturation compared with the control group (P<0.05).
Conclusions: Superior laryngeal nerve block combined with thyrocricocentesis TSA provides ideal and safe anesthesia to patients needing emergency tracheal cannulation for cerebral trauma.
