Randomized Controlled Trial Comparative Study
Effects of esmolol, lidocaine and fentanyl on P wave dispersion, QT, QTc intervals and hemodynamic responses to endotracheal intubation during propofol induction: a comparative study.
In our study we aimed to investigate the effect of esmolol, lidocaine and fentanyl on P-wave dispersion (Pwd), QT and corrected QT (QTc) durations and hemodynamic responses to endotracheal intubation during propofol induction. ⋯ We concluded that administration of esmolol before intubation prevents tachycardia and an increase in MAP, Pwd and QTc duration caused by laryngoscopy and tracheal intubation.

Randomized Controlled Trial Comparative Study
Study of 0.5% lidocaine alone and combination of 0.25% lidocaine with fentanyl and vecuronium in intravenous regional anesthesia for upper limb surgeries.
Intravenous regional anesthesia (IVRA) for upper limb surgeries with traditional high dose of lidocaine can lead to life threatening side effects. In order to avoid these potential life threatening side effects, many modified techniques of IVRA have been attempted by using a low dose of lidocaine, muscle relaxant and opioid. ⋯ Although the short delay observed in the onset and attainment of complete sensory and motor block may theoretically delay the start of surgery for 10-15 minutes but clinically that time will be spent in the preparation of surgical field. So this combination can be used safely and effectively in intravenous regional anesthesia for upper limb orthopedic surgeries with reduced chance of local anesthetic toxicity.

Randomized Controlled Trial
The assessment of memory under total intravenous anesthesia.
In this study, we aimed to assess implicit and explicit memory in patients who had abdominal surgery under total intravenous anesthesia (TIVA) with propofol and remifentanil, in which anesthesia level was controlled by bispectral index (BIS) monitoring. ⋯ Although no evidence of implicit memory under adequate anesthesia with TIVA was found, one patient showed explicit memory. Although adequate depth of anesthesia provided by BIS monitoring supports our implicit memory results, it does not explain the explicit memory results.

Comparative Study
Combined spinal-epidural anesthesia with epidural volume extension causes a higher level of block than single-shot spinal anesthesia.
We evaluated the effects of epidural injection with levobupivacaine or serum physiologic, epidural volume extension (EVE), when using combined spinal-epidural anesthesia (CSEA) for cesarean delivery. ⋯ Sufficient and rapid motor and sensory block was achieved in all the patients in the present study; however, motor and sensory block had faster onset, lasted longer, and was of a higher level in groups 2 and 3; these effects were more pronounced in the group 3.
