Randomised control trial to evaluate and compare effect of videographic and photographic visual aid use on optimal positioning for spinal anaesthesia

Central neuraxial block anaesthesia is most frequently used anaesthetic technique owing to its benefits, availability and low risk profile. Patient positioning and quality of landmarks form the cornerstone of successful neuraxial anaesthesia.  Studies shows that use of visual aids in the form of photographs helps in optimal patient positioning resulting in reduced time for successful dural puncture, number of skin punctures and high first pass success rate. Demonstration of optimal position will further help in achieving optimal position for neuraxial block.

We aim to study the effect of use of visual aids in the form of video graph  showing demonstration of optimal position for neuraxial anaesthesia compared to photographs of optimal position. Our primary outcome is to compare time required for successful dural puncture and secondary outcomes are first pass success, number of skin punctures, number of intervertebral spaces attempted, change of needle gauze, patient satisfaction and attending anaesthetist satisfaction.
