简介:目的:探讨氟比洛芬酯超前镇痛对腹腔镜下子宫切除术全麻患者拔管期应激反应和耐管的影响。方法:110例腹腔镜下子宫切除术患者,随机分成对照组和观察组各55例,两组患者均采用异丙酚、瑞芬太尼静复合全麻。对照组:手术前无超前镇痛,观察组:在手术前给予患者氟比洛芬酯超前镇痛。结果:在拔管时,观察组患者HR、MAP低于对照组患者HR、MAP,差异具有统计学意义(P<0.01);在手术结束和拔管时,两组患者的血糖和皮质醇均高于用药前,差异具有统计学意义(P<0.01);观察组患者血糖和皮质醇浓度低于对照组患者血糖和皮质醇浓度,差异具有统计学意义(P<0.01);观察组患者的耐管评分和拔管后疼痛VAS评分低于对照组患者耐管评分和拔管后疼痛VAS评分,差异具有统计学意义(P<0.01)。结论:在腹腔镜下子宫切除术全麻患者中采用氟比洛芬酯超前镇痛能有效的降低患者的心率、平均动脉压、血糖和皮质醇浓度,减少患者拔管后疼痛,提高患者预后。

简介:目的:观察含活性钙离子及神经酰胺3纳米化脂质体的护肤品缓解面部皮肤敏感症状的效果及其安全性。方法:采用多中心、治疗前后对照的临床试验方法,筛选127例面部皮肤敏感症状患者入组,受试期间面部单用皮肤屏障修护霜2周,期间避免外用及口服药物,收集患者的临床照片及症状评分表,比较患者在使用前、使用后1周及2周的主观症状(干燥、灼热、瘙痒)和客观症状(脱屑、红斑)评分,并计算有效率和显效率。结果:与使用前相比,面部皮肤敏感症状患者使用皮肤屏障修护霜1周后,干燥、瘙痒、灼热、脱屑、红斑五大皮肤敏感症状均得到明显改善,脱屑症状评分由(2.31±1.82)分减少为(0.83±1.09)分;红斑评分由(4.62±1.89)分减少至(3.01±1.81)分,主观症状干燥、瘙痒、灼热感的症状评分分别由(5.84±2.50)、(3.70±2.71)、(3.00±2.64)分减少为(3.67±2.16)、(2.05±2.24)、(1.50±2.11)分;持续使用2周后,脱屑、红斑、干燥、瘙痒、灼热等症状的评分继续降低至(0.55±0.93)、(2.13±1.83)、(2.67±2.16)、(1.52±2.01)、(0.93±1.70)分,与使用前、使用1周后比较,差异均有统计学意义(P值均〈0.05)。其缓解脱屑、红斑、干燥、瘙痒、灼热的有效率加显效率在1周时分别为82.1%、66.9%、68.7%、72.2%、75.8%,2周时分别为90.6%、85.6%、87.8%、84.2%、83.9%。结论:皮肤屏障修护霜对缓解干燥、灼热、瘙痒、脱屑、红斑等多种面部皮肤敏感症状具有一定的效果。
