Effects of simultaneous multi-level surgery intervention on the changes of the oxidative stress and the cognitive function in young and middle-aged patients with Moderate-severe obstructive sleep apnea hypopnea syndrome / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the effects of simultaneous multi-level surgery intervention on the changes of the oxidative stress and the cognitive function in young and middle-aged patients with moderate-severe OSAHS.@*METHOD@#One hundred and sixteen young and middle-aged patients with moderate-severe OSAHS received simultaneous multi-level surgery. PSG,malondialdehyde (MDA), advanced oxidation protein products (AOPP) and 8-isoprostaneF2α (8-iso-PGF2α) were tested, together with the evaluation of the questionnaires of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE) and Epworth sleepiness scale (ESS) before and 6 months after surgery.@*RESULT@#(1) The AHI, TS90% and LSaO₂ were all improved significantly 6 months after operation. No severe complications were observed in any patient. (2) The preoperative MoCA and MMSE scores were (23.52 ± 2.64) and (26.54 ± 1.07) respectively. The cognitive impairment were detected in OSAHS patients. MoCA was negatively correlated with AHI, TS90%, MDA, AOPP and 8-iso-PGF2a, while positively correlated with LSaO₂ (P < 0.05, r = -0.233, -0.190, -0.256, -0.247, -0.221 and 0.215, respectively). Cognitive impairment was mainly manifested as disorder in the visual space and execu- tive function, memory and delayed recall (mainly short-term memory). (3) MoCA and MMSE scores were both increased (P < 0.05) after the operation. MoCA showed negative correlations with MDA, AOPP, 8-iso-PGF2α, AHI and TS90%, and positive correlation with LSaO₂ (P < 0.05, r = -0.495, -0.463, -0.397, -0.332, -0.292 and 0.336, respectively).@*CONCLUSION@#Oxidative stress and cognitive dysfunction are closely related in young and middle-aged patients with Moderate-severe OSAHS. Oxidative stress may play an important role in cognitive function of young and middle-aged patients with Moderate-severe OSAHS. Multi-level surgery can improve oxidative stress so that to improve cognitive impairment.
