AI synopsis

What people are saying

Discussions emphasize the significance of the study by highlighting its multinational aspect and the notable sex differences in connected consciousness during anesthesia. Words like 'pivotal' and references to ongoing debates about anesthesia practices demonstrate a serious engagement with the implications of the research. Some discussions suggest that these findings could influence future clinical protocols, although most remain cautious, indicating a recognition of the study’s moderate but meaningful impact.

AgreementModerate agreement

Most discussions acknowledge the importance of the findings, especially regarding the higher incidence of connected consciousness in women, indicating general support for the study's relevance.

InterestHigh interest

The discussions show strong curiosity about the topic, with questions about clinical practices and the study's design. Words like 'pivotal', 'interesting', and 'needs more research' highlight engagement.

EngagementModerate engagement

Many discussions reference specific study details, such as its international scope, methodological choices, and findings on sex differences, demonstrating a deeper engagement.

ImpactModerate impact

While the discourse recognizes the significance of the findings, especially concerning patient outcomes and clinical implications, the overall perceived impact remains moderate with calls for further exploration.

Abstract in brief

Connected consciousness was observed in 11% of young adults (ages 18-40) after tracheal intubation, with higher incidence in females (13%) compared to males (6%).
The study utilized the isolated forearm technique to measure responsiveness and found that continuous anaesthesia before intubation significantly reduced the likelihood of connected consciousness.
Further research is needed to explore the sex-related differences in this phenomenon and its implications for anaesthesia practices.

But also that intraoperative connected consciousness (“waking up”) is nearly three times more likely in young women than men, showing we need to do more to provide equitable outcomes https://t.co/91IiCyRp7b

@DrBenMoran Certainly not an obligate response with “anaesthesia”. Pivotal study from Peter Schuller and colleagues. Really pleased we teamed up for ConsCIOUS2! #consciousness https://t.co/91IiCyRp7b

1回手を握るようにという命令に反応しました。この割合は女性の方が男性よりも2−3倍高いこともわかりました。この接続意識は、これよりさらに頻度が低く（1000人に1人）、麻酔から覚醒後もそれを覚えている「意図しない覚醒」とは区別されます。https://t.co/mswT3xchyN
