Clinical analysis of laryngeal mask airway anesthesia and endotracheal intubation anesthesia / 中国基层医药

ABSTRACT

Objective To study the safety and efficacy of laryngeal mask airway(LMA) used in breast cancer general anesthesia. Methods Forty ASA Ⅰ or Ⅱ patients with breast cancer scheduled for selective radical mastectomy under general anesthesia were allocated randomly to either laryngeal mask airway group(group A,n =20) or tracheal tube group(group B, n = 20). SBP, DBP, HR, SpO2 of patients before anesthesia(To)/after intubation immediately (T1) and 5 minutes(T2) after intubation tracheal tube or laryngeal mask intubation/after extubation immediately (T3) and 5 minutes(T4) of after extubation tracheal tube or laryngeal mask were recorded. The different incidence of anesthetic complications and side effect were observed in both groups because intubation and extubation. Results In group B, SBP, DBP and HR were significantly higher than those in group A at T1 and T3 (P ＜ 0.05). Agitation, bucking and pharyngodynia incidence rate in group B were significantly higher than group A(P ＜ 0.05). Conclusion Ventilation with LMA in patients underwent breast cancer radical correction was better than endotracheal intubation general anesthesia in keeping stable hemodynamics and producing less anesthetic complications.
