氯胺酮对全身麻醉后阴茎勃起治疗效果的观察

目的 探讨氯胺酮对全身麻醉后阴茎勃起的治疗效果.方法 2011年4月至2013年8月于宁波大学医学院附属医院接受手术治疗的男性患者共741例,其中18例麻醉后发生阴茎勃起为勃起组,余723例为无勃起组.勃起组患者采用静脉注射氯胺酮进行治疗.对勃起组阴茎萎缩变软的时间,注射前后患者的血压、心率、心律及2组麻醉苏醒时间、术后意识障碍、恶心呕吐等情况进行观察.结果 勃起组患者注射氯胺酮后阴茎萎缩变软的时间为（2.9 ±0.4） min;注射前患者的血压为（110±11）/（70 ±9） mmHg（1 mmHg=0.133 kPa）,明显低于注射后的（147±11）/（94±10） mmHg,差异有统计学意义（t=7.51,t=10.26,均P＜0.05）;注射后患者的心率为（89±9）次/min,明显快于注射前（64±8）次/rain,差异有统计学意义（=8.25,P＜0.05）.勃起组患者的麻醉苏醒时间、术后意识障碍率、术后恶心呕吐率与非勃起组患者相比,差异均无统计学意义（t=0.90,x2=0.60,x2=0.52,均P＞0.05）.结论 氯胺酮治疗全身麻醉后阴茎勃起疗效明显,安全迅速.

Efficacy observation of ketamine for the treatment of penile erection after general anesthesia

Objective To explore the efficacy of ketamine for the treatment of penile erection after general anesthesia.Methods Eighteen cases with penile erection after general anesthesia received in our hospital from Apr.2011 to Aug.2013 were given intravenous ketamine for treatment.The time of penis atrophy and soften,blood pressure,heart rate,rhythm,anesthesia time,postoperative unconsciousness,nausea and vomiting before and after injection of the patients were observed.Results The time of penis atrophy and soften of 18 patients after injection was （2.9 ±0.4） min.Patient＆#39;s blood pressure before injection was （110 ± 11）/（70 ±9） mmHg,which was significantly higher than that after injection [（147 ± 11）/（94 ± 10） mmHg] ; the difference was statistically significant （t =7.51,10.26,P 〈 0.05）.Patient＆#39;s heart rate after injection was （89 ± 9） times/min,significantly faster than that before injection [（64 ± 8） times/min] ; the difference was statistically significant （t =8.25,P 〈0.05）.The anesthesia time,postoperative unconsciousness rate,nausea and vomiting rate of 18 cases of patients with erectile using ketamine injections compared with patients with non-erectile had no significant differences （t =0.90,x2 =0.60,x2 =0.52,P 〉 0.05）.Conclusion Ketamine for the treatment of penile erection after general anesthesia is good.
