目的比较院前急危重症孕产妇急救中splendid双管喉罩与可视喉镜下插管的应用效果。方法应用随机数字表法将120例需建立人工气道的院前急危重症孕产妇随机分为观察组及对照组各60例,对照组接受可视喉镜下插管,观察组接受喉罩插管。记录2组患者麻醉诱导前(T_0)、气管插管时(T_1)、气管插管后1 min(T_2)、气管插管后3 min(T_3)、气管插管后5 min(T_4)心率(HR)、收缩压(SBP)、舒张压(DBP)水平。比较2组气管插管一次成功率及其所需时间、喉镜沾血情况。结果与T_0相比,2组患者T_1~T_4时段HR、SBP、DBP水平显著升高(P<0.05),但观察组T_1~T_4时段HR、SBP、DBP水平低于对照组,差异均有统计学意义(P<0.05)。观察组一次插管成功率高于对照组,气管插管所需时间短于对照组,喉镜沾血率低于对照组,差异均有统计学意义(P<0.05)。结论 splendid双管喉罩较经口可视喉镜下气管插管能有效减轻患者插管时应激反应,缩短患者插管时间,提高患者插管成功率。
Objective To compare the effect of intubation with splendid laryngeal mask and video laryngoscope in pre-hospital emergency critical care maternal emergency. Methods A total of 120 pregnant women with severe acute respiratory syndrome requiring artificial airway were randomly divided into observation group (60 cases) and control group (60 cases) by random number table method. The control group received intubation under visual laryngoscope, while the observation group received laryngeal mask Intubation. The heart rate (T_0), tracheal intubation (T_1), tracheal intubation 1 min (T_2), intratracheal intubation 3 min (T 3) and tracheal intubation 5 min (T 4) HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP). The success rate of the two tracheal intubation and the time required for laryngoscopy were compared. Results Compared with T 0, the levels of HR, SBP and DBP in group T 1 ~T 4 were significantly increased (P <0.05), but the levels of HR, SBP and DBP in group T 1 ~T 4 were lower than those in control group Significance (P <0.05). The success rate of primary intubation in observation group was higher than that in control group. The time required for tracheal intubation was shorter than that in control group, and the laryngoscopy stained rate was lower than that in control group. The difference was statistically significant (P <0.05). Conclusions Splendid laryngeal mask is more effective than tracheal intubation under oral laryngoscopy to reduce stress during intubation, shorten the time of intubation and improve the success rate of intubation.
