METHODS: Sixty patients were randomized into two groups with Group B receiving 4 mg bupivacine 0.5%+25 μg fentanyl and Group P receiving 50 mg prilocaine 2%+25 μg fentanyl intrathecal. Block quality and duration, postanesthesia care unit stay and adverse effects were compared.
RESULTS: Block durations and postanesthesia care unit stay were shorter in Group B than in Group P (p<0.001 in both). Hypotension and bradycardia were not seen in Group B which was significantly different than in Group P (p=0.024 and p=0.011 respectively).
CONCLUSIONS: Intrathecal 4 mg bupivacaine + 25 μg fentanyl provided adequate spinal anesthesia with shorter block duration and postanesthesia care unit stay with stable hemodynamic profile than intrathecal 50 mg prilocaine + 25 μg fentanyl for day case transurethral resection of prostate surgery in geriatric patients.
