背景鉴于氯胺酮联合曲马多用于患者手术后镇痛的研究较少，本文旨在验证曲马多复合氯胺酮能否改善腹部大手术的术后镇痛效果。方法在此项双盲、随机、对照研究中，行择期开腹手术的成年患者（n=120）随机分入氯胺酮组（氯胺酮手术中用量为0．3mg／kg，手术后以0．1mg·kg^-1·h^-1速度输注）或对照组（相同剂量和速度的生理盐水）。所有患者在手术中均使用曲马多3mg／kg，手术后48小时持续输注曲马多0．2mg·kg^-1·h^-1另以患者自控吗啡镇痛用于补救性镇痛。结果在整个48小时研究期间，氯胺酮组在静息（p=0．01）和活动（p=0．02）时的疼痛评分较低，吗啡的需求量较少（p=0．003）。在0～24小时期间，氯胺酮改善了患者主观的镇痛效果（p=0．008），镇静作用较小（p=0．03），需要医师干预的严重疼痛较少（p=0．01）。氯胺酮组中产生幻觉的患者较多，但两组的其他副作用均相似。结论腹部大手术后，小剂量氯胺酮是辅助吗啡和曲马多镇痛的有效药物。

Objective: To determine the early electrocardiographic changes in a cohort of ambulatory cameroonian COVID-19 patients treated with hydroxychlo- roquine and Azithromycin. Design: Prospective study. Setting: Treatment centres of the city of Yaounde, Cameroon, from May 7p>thp> to 24p>thp> 2020. Participants: We enrolled 51 consecutive confirmed COVID-19 on RT-PCR who having mild forms of COVID-19 and treated by hydroxychloroquine 200pan> mg twice daily during seven #days plus Azithromycin 500 mg the first day and 250 mg the remaining 4 days as per national standard. Main Outcomes Measures: The primary end-point was the change in QTc interval between day 0 (D0), day 3 (D3) and day 7 (D7). Secondary endpoints were changes in all other cardiac electrical conductivity patterns and the occurrence of clinical arrhythmic events during the course of treatment. Results: pan style="font-family:Verdana;">The population (29 men and 22 women) was aged 39 ± 11 years (range 17 to 61 years
