Aging population is a major demographic trend worldwide. Globally, 50% of all the elderly individuals are estimated to undergo atleast one surgical procedure and post-operative cognitive dysfunction (POCD) is one of the most common and often poorly understood post-operative complications in this section of the population. This randomised prospective study was conducted to assess the post-operative cognitive status in the elderly undergoing non-cardiac surgery, evaluate the cognitive parameters affected, evaluate the potential risk factors and thereby analyse the potential for implementation of preventive strategies. ⋯ POCD is a definite complication after surgery and anaesthesia in the elderly population. Gender emerged as a significant risk factor with increasing age as a dominating factor contributing to POCD.

Central venous catheter (CVC) insertion induces pain and discomfort to a conscious patient despite application of a local anaesthetic (LA) field block and this pain can be greatly lessened by using additional analgesics. The aim of this study was to evaluate the efficacy of dexmedetomidine along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. ⋯ Pre-procedural bolus dexmedetomidine infusion provides adequate analgesia and patient comfort for CVC insertion along LA field block. However, the tendency for excessive sedation and bradycardia associated with dexmedetomidine render it less desirable for this purpose.

The choice of anaesthetic agent for electroconvulsive therapy (ECT) depends on seizure duration, haemodynamic, and recovery parameters. The aim of the study was to assess the effects of ketamine-propofol induction with dexmedetomidine preadministration (ketofol-dex group) and without its preadministration (ketofol group) on haemodynamics, depression, seizure duration, recovery characteristics, and agitation following ECT in patients with depression. ⋯ Ketofol-dex mixture in ECT is associated with longer mean seizure duration, effective anti-depression, less incidence of agitation, more patient satisfaction, and acceptable decreases in blood pressure and HR when compared to ketofol alone.
