目的:观察白内障超声乳化术中高灌注压对急性闭角型青光眼(acute angle-closure glaucoma,AACG)患者术后视功能的影响。方法:选择2017-03/2018-10于我院住院并行白内障超声乳化摘除人工晶状体植入联合房角分离的AACG合并白内障的患者35... 目的:观察白内障超声乳化术中高灌注压对急性闭角型青光眼(acute angle-closure glaucoma,AACG)患者术后视功能的影响。方法:选择2017-03/2018-10于我院住院并行白内障超声乳化摘除人工晶状体植入联合房角分离的AACG合并白内障的患者35例37眼,比较术前、术后3、6mo最佳矫正视力(BCVA)、眼压、平均视敏度(MS)、平均缺损(MD)和丢失方差平方根(sLV)值的变化。结果:与术前相比,患者术后3、6mo BCVA、MS明显改善,MD和sLV明显下降,眼压显著降低(P<0.001),术后3、6mo组间比较无差异(P>0.05)。结论:白内障超声乳化术中高灌注压不会对AACG患者术后视功能造成损伤。 展开更多

Objective: To study the changes between cerebral oxygen (O 2) delivery and uptake in dogs resuscitated under normotension or hypertension for 4 h. Methods: The model of ventricular fibrillation of 8 min in 12 dogs was made, followed by open cardiopulmonary resuscitation, reperfusion with normal or high mean arterial pressure (MAP), and controlled ventilation to 4 h. Animals were randomly assigned into Group NT (normotensive reperfusion, n=6) and Group HT (hypertensive reperfusion, n=6). Cerebral arteriovenous (sagittal sinus) O 2 content difference (Ca-ssO 2) and venous (sagittal sinus) PO 2 (PssO 2) were determined before cardiac arrest (CA) and 30, 60, 120, and 240 min after CA. Results: In Group NT, Ca-ssO 2 was lower at 30 min (P<0.05) but higher at 240 min (P<0.01) after CA than that before CA. In Group HT, Ca-ssO 2 was not significantly different from that in Group NT before CA but was lower than that in Group NT at 30 min after CA (P<0.01). Ca-ssO 2 was not significantly different in Group NT and HT thereafter. In both groups, PssO 2 was both higher at 30 min after reperfusion (P<0.01) and at 240 min after reperfusion lower (P<0.05) than those before CA .At 30 min after reperfusion, PssO 2 was higher (P<0.01) in Group HT than that in Group NT, with insignificant difference between two groups. Conclusion: Cerebral O 2 delivery and uptake are mismatched after CA and resuscitation. Hypertensive reperfusion improves oxygen delivery to the brain early after CA. 展开更多
