A Comparative Analysis of Pain Control Methods after Ankle Fracture Surgery with a Peripheral Nerve Block: A Single-Center Randomized Controlled Prospective Study.

: Patients experience severe pain after surgical correction of ankle fractures. Although their exact mechanism is unknown, dexamethasone and epinephrine increase the analgesic effect of anesthetics in peripheral nerve blocks. This study aimed to compare the postoperative pain control efficacy of peripheral nerve blocks with ropivacaine combined with dexamethasone/epinephrine and peripheral nerve blocks with only ropivacaine and added patient-controlled analgesia in patients with ankle fractures.

The effect of ketamine on tracheal intubating conditions without neuromuscular blockade during sevoflurane induction in children.

Purpose: The purpose of this study was to investigate the effect of ketamine on intubating conditions for tracheal intubation during anesthesia induction with sevoflurane and alfentanil in pediatric patients.

Methods: After obtaining parental consents, 50 children, aged 3-10 years, were randomly allocated into two groups to receive either i.v.
