Abstract:
Objective To observe the effect of flexible laryngeal mask (FLMA) in transnaso-sphenoidal microsurgery for pituitary adenoma on airway management and variation of stress response.Methods One hundred patients (71 males, 29 females, aged 18-65 years, BMI 21-28 kg/m2, ASA physical status Ⅰ or Ⅱ) undergoing transnaso-sphenoidal microsurgery for pituitary adenoma were randomly divided into two groups: the FLMA group (group F) and the reinforced endotracheal tube group (group T) using a random number table, 50 cases in each group.The plasma concentration of epinephrine and norepinephrine were measured before anesthesia induction (T0), at the time of inserting the FLMA or reinforced endotracheal tube (T1), 1 min (T2) and 5 min (T3) after insertion.The Berry scores of the preoperative and postoperative airway exposure by branchofiberoscope in group F were assessed.The time of removal of FLMA (endotracheal tube) and the occurrence of choking, laryngeal spasm, sore throat, hoarseness and other adverse reactions were recorded.Results The levels of epinephrine and norepinephrine were were significantly lower at T2 and T3 in group F than those in group T (P<0.05).There was no significant difference in airway Berry scores.The time of extubation was shorter in group F than that in group T [(9±3) min vs (17±6) min] (P<0.05).The incidence of choking (2% vs 22%) and sore throat (4% vs 30%) were significantly lower in group F than those in group T (P<0.05).Conclusion Compared with the reinforced endotracheal tube, FLMA can be applied safely and effectively to transnaso-sphenoidal microsurgery for pituitary adenoma, reduces stress respond associated with anesthesia and post-extubation complications, improves the recovery of patients.
