简要总结
Spinal anesthesia has been a popular method of anaesthesia for short, lower abdominal surgeries. Hyperbaric racemic bupivacaine is commonly used for spinal anaesthesia due to its long duration of action and combined motor and sensory blockade. However there are other preparations which can be used for the same with its own advantages and disadvantages.
The impetus for the development of the newer stereoselective, single enantiomer amide local anaesthetic agents, ropivacaine and levobupivacaine, came from reports of fatal cardiac toxicity in pregnant women receiving epidural bupivacaine and etidocaine for Caesarean section. Although these concerns are not clinically relevant to spinal anaesthesia because of the smaller doses required, there has, nevertheless, been interest in the potential of these agents for intrathecal use.
Intrathecal use of hyperbaric LA agents has become more popular as they produce predictable block characteristics and reliable SA. Ropivacaine, a newer amino-amide local anesthetic (LA) agent similar to bupivacaine in chemical structure, but 30-40% less potent than bupivacaine has been well-studied for spinal anesthesia (SA). The preliminary studies evaluated the efficacy and safety of isobaric ropivacaine for neuraxial blockade.
Intrathecal ropivacaine was found to be safe, having shorter duration of action than bupivacaine and lesser incidence of transient neurological symptoms (TNS) as compared with intrathecal lignocaine.
Another formulation of a local anesthetic, i.e., hyperbaric levobupivacaine is being made more available in India. It is known that levobupivacaine has a lower propensity to cause hypotension and bradycardia and causes early motor recovery. This study aims to compare the effects of hyperbaric ropivacaine and hyperbaric levobupivacaine on its use in pregnant women during elective LSCS. The new introduction of hyperbaric levobupivacaine in India and the lacunae in literature with respect to its comparison with hyperbaric ropivacaine, in terms of hemodynamic parameters, justifies the need for this study
