Objective: To observe the anesthetic effect of modified anesthesia in the bronchoalveolar lavage.
Method: 118 cases randomly fell in two groups: traditional group: intramuscular injection of 10 mg diazepam prior to routine anesthesia; modified group: preoperative intramuscular injection of 50 mg dolantin,and venous injection of 2 ml physiological saline, 10 mg dexamethasone, 5 mg ephedrine; observe the anesthetic effect, satisfaction and lavage quantity in patients.
Results: The excellence rate and satisfaction of anesthetic effect are both 100% in modified group while 82.76% and 76.2% in the tradition group. The result indicates the excellence rate and satisfaction of anesthetic effect in modified group are better than the traditional group with a significant difference (P<0.05); the lavage quantity in the modified group is significantly higher than that in the traditional group with a significant difference (P<0.01 ).
Conclusion: Dolantin, dexamethasone and ephedrine preoperatively used with a good anesthetic effect can improve the cooperation of patients in bronchoalveolar lavage with less pain and increased lavage quantity, thereby worthy of clinical application.
