Prophylactic phenylephrine infusion is superior to bolus dosing in avoiding maternal hypotension in women receiving neuraxial anaesthesia for caesarean section, although is also associated with more hypertension and bradycardia.
Large Lanuguage Models may outperform physicians on diagnostic tasks, but simply providing access to AI tools does not improve doctors' diagnostic reasoning without effective integration.
When suitable for the surgery, using an LMA instead of ETT may reduce postoperative atelectasis by allowing faster airway placement and requiring less muscle relaxation.
General anaesthesia, particularly with optimised ventilation strategies (either HFJV or HFLTV), appears to improve AF ablation outcomes through enhanced catheter stability.
Dexamethasone is the most effective adjuvant for prolonging local anaesthetic infiltration, likely superior to dexmedetomidine, clonidine, NSAIDs, opioids and magnesium.
Following inadvertent dural puncture, insertion of an intrathecal catheter can provide both excellent labour analgesia and be used if necessary for caesarean section, however IT catheters carry risks and complexities that anaesthetists must be aware of.
A significant proportion of patients experience recallable dreams during anaesthesia, apparently higher with propofol induction & maintenance, and when pre-induction psychological suggestion is used.
