Objective To evaluate the effect of the patient's preoperative visit to the operating room on the patient's apprehension before operation.Methods One hundred and Sixty patients aged 16-64 yr with fear visual analog scale (FVAS) score≥4 scheduled for elective surgery were randomly divided into 2 groups(n=80 each):control group and study group.In control group the anesthesiologists visited their patients the day before operation ns usual;while in study group the anesthesiologists brought their patients to the operating room,showed them the environment and anesthesia equipment and assured of the safety of the operation and anesthesia.The degree of fear was scored according to FVAS (O=no fear,1-3 mild,4-6 moderate,7-10 severe) and was evaluated on the 1st morning after admission(T1),the night before operation(T2)and before induction of anesthesia(T3).MAP and HR at T1-3 and blood glucose level at T1,3 were mensured and recorded.Results The patient's preoperative apprehension was significantly allayed by patient's preoperative visit to the operating room.The MAP,HR,incidence of moderate and severe fear at T2,3 and blood glucose level at T3 were significantly lower in study group than in control group.Conclusion Patient's preoperative visit to the operating room can allay precperative apprehension.

Objective To evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with gabapentin for treatment of recurrent pain after trigeminal radiofrequency thermocoagulation.Methods Forty patients of both sexes suffering from recurrent pain after trigeminal radiofrequency thermocoagulation,who refused surgical treatment,aged 45-80 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with visual analog scale score ≥4,with the course of recurrent pain 0.5-17.0 months,were randomized into 2 groups (n =20 each) using a random number table:gabapentin group (group A) and gabapentin plus rTMS group (group B).The patients were treated with 2 courses of rTMS in total (5 days for 1 course,1 time per day) and with the second course at a 2-day interval in group B.Effective analgesia and pain relief were recorded within 6 months after treatment,and the therapeutic efficacy was evaluated according to the modified Macnab criteria.The daily consumption of gabapentin and development of rTMS-and gabapentin-related adverse reactions were recorded.Results No rTMS-related adverse reactions were found in group B.Compared with group A,the rates of effective analgesia and pain relief were significantly increased,the therapeutic efficacy was enhanced,the daily consumption of gabapentin was decreased,and the incidence of gabapentin-related adverse reactions was decreased in group B (P＜0.05).Conclusion Combination of rTMS and gabapentin produces better efficacy than gabapentin alone when used to treat the recurrent pain after trigeminal radiofrequency thermocoagulation,and the safety is good.
