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.
ABSTRACT
Objective To discussion the effect of endoscopic single nostril transsphenoidal pituitary tumor resection on improving clini-cal symptoms and related quality of life of patients. Methods Selected 114 cases of patients with pituitary tumors in our hospital from August 2013 to August 2015, and randomly divided them into the nasal endoscopic group and the microscopic group according to the random number table,with 57 patients in each group. Patients of the 2 groups were treated with nasal endoscopic and microscopic single nostril transsphenoi-dal pituitary tumor resection respectively. The operation situation,hormone decline,incidence of complications after surgery and SNOT-20 and VAS score of the two groups were compared. Results Operative time of nasal endoscopic group was significantly higher than that in the mi-croscopic group,whlie the blood loss,length of hospital stay in endoscopic group was significantly lower than the microscopic group,and the difference was statistically significant (P0. 05). One week after operation,cerebrospinal fluid cell count,cerebrospinal fluid protein,adrenocorticotropic hormone,serum chloride,sodium, growth hormone,and prolactin levels of the nasal endoscopic group were lower than the microscopic group (P<0. 05). The complication rate was 14. 9% in the nasal endoscopic group,which was obviously lower than 59. 6% in the microscopic group (P<0. 05). One week after operation,the SNOT-20 scores and VAS scores were increased in both of the two groups,but the microscopic group increased more significantly (P<0. 05). Conclusion Endoscopic single nostril transsphenoidal pituitary tumor resection surgery cost longer operation time,but it lead to less trauma and less postoperative complications,which may delay the decline of patients’ quality of life and promote the improvement of prognosis.
