Randomized Controlled Trial Comparative StudyIntrathecal chloroprocaine vs. lidocaine in day-case surgery: recovery, discharge and effect of pre-hydration on micturition.
Spinal chloroprocaine may be more suitable for day-case surgery than lignocaine because of faster block resolution and time to discharge.

Randomized Controlled TrialHeart rate variability dynamics during controlled hypotension with nicardipine, remifentanil and dexmedetomidine.
This study was done to investigate how nicardipine, remifentanil and dexmedetomidine affect the balance of the autonomic nervous system in patients receiving controlled hypotension under general anaesthesia by evaluating heart rate variability indices. ⋯ Remifentanil and dexmedetomidine did not have sympathetic nervous system-stimulating effects during controlled hypotension, while remifentanil seemed to be superior in preserving the overall balance in autonomic nervous system activity. Nicardipine was found to stimulate the sympathetic nervous system, which may be problematic in patients vulnerable to disturbances in the autonomic nervous system.
