Randomized Controlled Trial
Low-dose neostigmine to antagonise shallow atracurium neuromuscular block during inhalational anaesthesia: A prospective randomised controlled trial.
Even shallow residual neuromuscular block [i.e. train-of-four (TOF) ratio around 0.6] is harmful. It can be effectively antagonised by small doses of neostigmine, but reports are limited to intravenous anaesthesia. Inhalational anaesthesia may enhance neuromuscular block and delay recovery. It is not known whether low doses of neostigmine are still effective in the context of inhalational anaesthesia. ⋯ Under desflurane anaesthesia, neostigmine 10 µg kg(-1) is effective in antagonising shallow atracurium block. Compared to no neostigmine, the time to a TOF ratio more than 0.9 was shortened and neuromuscular recovery at 5 and 10 min was more advanced.

Comparative Study
Effects of isoflurane-induced anaesthesia on cognitive performance in a mouse model of Alzheimer's disease: a randomised trial in transgenic APP23 mice.
Results from in-vitro experiments suggest that inhalational anaesthetics may have a detrimental effect on the course and incidence of Alzheimer's disease. However, case-control studies in humans show no negative impact of anaesthetics on the course of Alzheimer's disease. ⋯ Isoflurane may have protective, rather than detrimental, effects on cognition in Alzheimer's disease.
