Estimation of Duration of Analgesia in Patients Being Administered With 0.5% Levobupivacaine: A Cross Sectional Observational Study in A Medical College Of Trans-Himalayan Region

Various local anaesthetic agents like bupivacaine, levobupivacaine, ropivacaine and lignocaine have been used with safety and efficacy in performing such blocks. Out of various agents which are used for brachial plexus block, levobupivacaine is the agent which not only prolongs motor and sensory blockade but is also less cardiotoxic and neurotoxic. The study was done with an objective to estimate the duration of analgesia and the requirement of rescue analgesia post operatively. We also intended to study the intra-operative cardiovascular stability by assessing the heart rate and mean arterial pressure of the study participants. There were 30 study participants who were provided with 0.5% Levobupivacaine plus dexamethasone 4 mg. The mean duration of the surgery was 58.83 (SD=27.41) minutes. The mean duration of the pain free period was 567 minute
