Summary: Abstract: A failed spinal block can be very frustrating for the anesthesiologist and patient. The incidence of high or total spinal block is highr after a repeat spinal tap, along with the additional pain, and anxiety for the patient. This study aims to find out whether a subarachnoid block without barbotage will lessen the incidence of failed block. One hundred twenty subjects for abdominal surgery under subarachnoid block were enrolled in this randomized double-blinded study. They were divided into Group A (Barbotage), and Group B (without Barbotage). The block was assessed using the Modified Bromage scale, and the pin prick test. Failure to achieve Bromage 0, and T4 level block by pin prick test was deemed as failed block. Group A had a 6% failure rate, and Group B had no failure. There was a significant difference in the incidence of spinal block failure between the group with barbotage, compared with the group without barbotage (p=0.013). The incidence of failure rate was higher in the Barbotage group. Needle tip displacement, and the arachnoid mater acting as flap valve could have caused the spread of the anesthetic into the subdural space instead of the subarachnoid space.
