ABSTRACT : The aim was to study the safety and efficacy of both drugs in geriatric patients as well as the incidence of anaesthetic complications.

METHODS : The study consisted of 30 ASA I & II patients in each group. Paired ‘t’ test was applied for haemodynamic variables (pulse,BP,sPO2) and unpaired ‘t’ test between group comparisons for onset and duration of sensory and motor blockade.

RESULTS : The results showed significant increase in pulse rate and fall in blood pressure in Bupivacaine group.Offset of motor blockade was significantly faster in Ropivacaine group thus enabling early ambulation

CONCLUSIONS : Ropivacaine proved a better choice of drug for spinal anaesthesia in geriatric patients for TURP surgery.

A Comparative study of hyperbaric Bupivacaine 0.5% and isobaric Ropivacaine 0.75% in Geriatric patients undergoing TURP surgery was conducted in Urosurgery Operation theatre in LTMGH, Mumbai.

The studyconsisted of 30 ASA I & II patients in each group. Theaimwas to study the safety and efficacy of both drugs in geriatric patients as well as the incidence of anaesthetic complications.

Paired ‘t’ test was applied for haemodynamic variables (pulse,BP,sPO2) and unpaired ‘t’ test between group comparisons for onset and duration of sensory and motor blockade.

The results showed significant increase in pulse rate and fall in blood pressure in Bupivacaine group. There were 2 cases of bradycardia in the same group. Haemodynamics were stable in Ropivacaine group throughout the procedure. Offset of motor blockade was significantly faster in Ropivacaine group thus enabling early ambulation with the same duration of sensory blockade in both groups. Thus, Ropivacaine proved a better choice of drug for spinal anaesthesia in geriatric patients for TURP surgery.
