Abstract:
Objective:To compare the effect of gum elastic bougie and laryngoscope on the stress response to endotracheal intubation in critically ill patients.
Methods:A total of 110 cases patients admitted to intensive care unit who needed intubaton from January 2015 to December 2017 were randomly divided into 2 groups: gum elastic bougie group (gum elastic bougie was used for intubation) and Macintosh laryngoscope group(laryngoscope intubation was performed) with 55 patients in each group. The mean arterial blood (MAP) and heart rate (HR) were recorded before intubation(T0), 1 min after intubation (T1), 3 min after intubation(T2) and 5 min after intubation(T3). The concentration of norepinephrine(NE) and epinephrine(E) in the vein were measured at T0 and T2.
Results:The levels of MAP, HR, NE and E were increased in both groups after intubation (P<0.05). At T1, T2 and T3, the levels of MAP in gum elastic bougie group [(101.5 ± 6.4), (92.1 ± 3.3), (84.4 ± 7.7) mmHg, 1 mmHg=0.133 kPa] were significantly lower than those in Macintosh laryngoscope groupgroup [(116.2 ± 17.8), (110.4 ± 9.7), (97.5 ± 6.4) mmHg](P<0.05). The level of HR in gum elastic bougie group at T1 [(95.4 ± 7.9) times/min] was significantly reduced than that in Macintosh laryngoscope group [(112.7 ± 12.6) times/min](P<0.05). After intubation, the concentration of NE and E in gum elastic bougie group [(161.28 ± 10.45), (105.04 ± 7.31) ng/L] were reduced than those in Macintosh laryngoscope group [(189.32 ± 11.56), (128.61 ± 3.68) ng/L], there were significant differences between two groups (P<0.05).
Conclusions:Compared with normal laryngoscope, gum elastic bougie guided intubation is of great significance in terms of better hemodynamics and less stress response.
