evaluate the efficacy of hyaluronidase in different doses as an adjuvant to bupivacaine in ultrasound-guided TAB block during CS

Hyaluronidase acts by catalyzing the hydrolysis of hyaluronan, decreased its viscosity, and enchasing the tissue permeability. So, this makes it a suitable additive for other drugs to speed up their distribution and delivery especially in ophthalmic surgery. Several studies showed that multiple injection techniques of TAB block were more successful with a faster onset of anesthesia and higher success rates, with a change in the incidence of complications. This double-blinded randomized prospective study was conducted to evaluate the efficacy of hyaluronidase in different doses as an adjuvant to bupivacaine in ultrasound-guided TAB block during CS . The primary outcome of this study was the duration of sensory block, while secondary outcomes included the onset of sensory block, success rate, total doses of intraoperative rescue analgesia, number of patients needed for postoperative rescue analgesia, and complications.
