Abstract

INTRODUCTION

Our aim was to examine whether surgery with regional anesthesia (RA) is associated with accelerated long-term cognitive decline comparable with that previously reported after general anesthesia (GA).

METHODS

Longitudinal cognitive function was analyzed in a cohort of 1819 older adults. Models assessed the rate of change in global and domain-specific cognition over time in participants exposed to RA or GA.

RESULTS

When compared with those unexposed to anesthesia, the postoperative rate of change of the cognitive global z-score was greater in those exposed to both RA (difference in annual decline of -0.041, P = .011) and GA (-0.061, P < .001); these rates did not differ. In analysis of the domain-specific scores, an accelerated decline in memory was observed after GA (-0.065, P < .001) but not RA (-0.011, P = .565).

CONCLUSIONS

Older adults undergoing surgery with RA experience decline of global cognition similar to those receiving GA; however, memory was not affected.

摘要

简介

我们的目的是检验在区域麻醉(RA)下进行手术是否与先前报道的全身麻醉(GA)后相似的加速长期认知衰退有关。

方法

对 1819 名老年患者的队列进行了纵向认知功能分析。模型评估了暴露于 RA 或 GA 下的参与者在不同时间的整体和特定领域认知的变化率。

结果

与未接受麻醉的患者相比,接受 RA(每年下降差异为-0.041,P=0.011)和 GA(-0.061,P<0.001)的患者术后认知总体 z 分数的变化率更大;这些变化率没有差异。在特定领域评分的分析中,GA 后观察到记忆的加速下降(-0.065,P<0.001),而 RA 后则没有(-0.011,P=0.565)。

结论

接受 RA 下手术的老年患者经历的整体认知下降与接受 GA 者相似;然而,记忆并未受到影响。
