OBJECTIVE:To observe the clinical efficacy and safety of flunarizine combined with salvianolate in the treatment of acute migraine. METHODS:A total of 72 patients with acute migraine were randomly divided into control group(36 cases)and observation group (36 cases). Based on routine treatment,control group was given Flunarizine hydrochloride capsules orally,10 mg for 65 year-old and below once a day,5 mg for more than 65 year-old once a day. Observation group was additionally given Flunarizine hydrochloride for injection 200 mg intravenously,once a day,on the basis of control group. Both groups were treated contineously till cured or for 2 weeks. Clinical efficacy,onset time,recovery time,VAS score,frequency and duration of head-ache attack,ADR were observed in 2 groups. RESULTS:In the course of treatment,the two groups did not terminate and fall off, and all of them completed the treatment. The total response rate(97.22%)of observation group was significantly higher than that (86.11%)of control group;onset time and recovery time of observation group were both shorter than those of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in VAS score,frequency or duration of headache attack between 2 groups (P>0.05). After treatment,VAS score,frequency and duration of headache attack in 2 groups were all significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLU-SIONS:Based on routine treatment,flunarizine hydrochloride capsules combined with Salvianolate injection show significant effica-cy for acute migraine with good safety.

Objective To discuss the feasibility and safety of sevoflurane inhale anesthesia with portable combined inhalation anesthesia induction device in solving the difficulty of children entering the operation room.Methods One hundred pediatric patients were enrolled into the study.The pediatric patients were randomly divided into two groups,50 cases in each group.Group A was fraught with a new mode of administration,using portable combined inhalation anesthesia induction device with sevoflurane 2 ml before entering the operation room;group B was fraught with a traditional mode of administration,using in-tramuscular injection with ketamine 4-5 ml/kg before entering the operation room.The analog scale of anes-thetic effect,the number of body movement,adverse reaction were compared between the two groups. Results Compared with group B,time of falling asleep and retention time in the operating room was signif-icantly shorter (P <0.01).And body movement during vein puncture decreased significantly (P <0.01). Moreover,the incidence of adverse affect showed significant reduce compared with group B (P < 0.05 ). Conclusion The combined inhalation anesthesia induction device is simple to produce and easy to carry.To solve the difficulty of convoying children into the operating room,combined inhalation anesthesia induction device with sevoflurane is more effective, safer and more humanized way when compared with the traditional one.
