Randomized Controlled Trial Comparative Study
The optimal dose of esmolol and nicardipine for maintaining cardiovascular stability during rapid-sequence induction.
To determine the optimal dose of esmolol in combination with nicardipine in effectively blocking undesirable cardiovascular responses during rapid-sequence induction. ⋯ The combination of nicardipine 20 μg/kg and esmolol 0.5 mg/kg most effectively attenuates the cardiovascular responses during rapid-sequence induction.

Randomized Controlled Trial Comparative Study
Tramadol-metoclopramide or remifentanil for patient-controlled analgesia during second trimester abortion: a double-blinded, randomized controlled trial.
To compare patient-controlled analgesia (PCA) with tramadol with PCA with remifentanil in second trimester abortion. ⋯ Both drugs are acceptable choices for pain control in patients undergoing second trimester abortions.

Randomized Controlled Trial Comparative Study
Nerve stimulator versus ultrasound guidance for placement of popliteal catheters for foot and ankle surgery.
To determine whether ultrasound guidance improves the quality of continuous popliteal block when compared with a nerve stimulator after major foot and ankle surgery. ⋯ Ultrasound guidance was associated with less local anesthetic consumption than with the nerve stimulator; however, there was little clinical benefit, as all other outcomes were similar between groups.
