An Observational Study To Comparethe Efficacy Of Intrathecal Hyperbaric Ropivacaine (0.75%) And Hyperbaric Lignocaine (5%) In Patients Undergoing Tubal Ligation Surgeries

Abstract

Ropivacaine is a long-acting amide local anaesthetic agent and first produced as a pure enantiomer. It produces effects similar to other local anaesthetics via reversible inhibition of sodium ion influx in nerve fibres. The efficacy of ropivacaine is similar to that of bupivacaine and levobupivacaine for peripheral nerve blocks and, although it may be slightly less potent than bupivacaine when administered epidurally or intrathecally, equi-effective doses have been established.

Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anaesthetic of the amino amide type. It is also used to treat ventricular tachycardia. [7][8]  When used for local anaesthesia or in nerve blocks,lidocaine typically begins working within several minutes and lasts for half an hour to three hours.

Objective: To compare the efficacy of INTRATHECAL HYPERBARIC ROPIVACAINE (0.75% ) AND HYPERBARIC LIGNOCAINE (5%) IN PATIENTS UNDERGOING TUBAL LIGATION SURGERIES.

Methods: An observational study was conducted among 50 patients planned for tubal ligation surgeries. They were grouped into Group-R (Ropivacaine  group) & Group-L (Lignocaine group) with 25 patients in each group.  Spinal anaesthesia was given as per protocol under aseptic precautions. Group R had received 2 ml (0.75%) hyperbaric Ropivacaine while Group L had received had received 2 ml (5%) hyperbaric Lignocaine. Onset and Duration of sensory and motor blockade, 2 segment regression, highest level , hemodynamic changes, and adverse effects if any were observed
