Objective To compare the clinical efficacy and tolerability of 0 75% ropivacaine(8~10ml) versus 1% lidocaine plus 0 2% dicaine in epidural anesthesia cesarean section.
Methods 115 cases(211 eyes) under-went glaucoma surgeries under surface anesthesia with 0.5% Alcaine or 0.5% Dicaine eye drops combined with subconjunctival anesthesia with 2% Lidocaine.
Conclusions the repeated surface anaesthesia with low-concentration Dicaine is safe and effective, and it is a better choice in endoscopic surgery for chronic nasosinusitis and nasal polyp.
