Appropriate determination of tidal volume (VT) is important for preventing ventilation induced lung injury. We compared hemodynamic and respiratory parameters in two conditions of receiving VTs calculated by using body weight (BW), which was estimated by measured height (HBW) or demi-span based body weight (DBW). ⋯ Estimated VT based on measured height is higher than that based on demi-span and this difference exists only in females, and this higher VT results higher airway pressures during mechanical ventilation.

Supraclavicular brachial plexus block is one of the most effective anesthetic procedures in operations for the upper extremity. Ketamine has been reported to enhance the analgesic effects of local anesthetics. We have conducted this study to assess whether coadministration of ketamine can prolong the local analgesic effect of lidocaine in the supraclavicular brachial plexus block for patients undergoing elective upper extremity surgery. ⋯ The addition of ketamine to lidocaine in the ultrasound-guided brachial plexus block could decrease the postoperative pain and need for analgesic. Therefore, it could be considered as an option in the brachial plexus block to enhance the analgesic action of lidocaine.

There is a high tendency among specialists to treat the addicts with naltrexone; withdrawal symptoms are frequent after taking naltrexone along with opioids. This study investigated the frequency of agitation due to inappropriate use of naltrexone in addicts. ⋯ Considering the high prevalence of agitation in the poisoning emergency department due to inappropriate use of naltrexone, more accurate planning for administration of naltrexone in addicts seems necessary.

Lidocaine 7%-tetracaine 7% is one of the combinations recently offered for performing laser-assisted hair removal. The aim of this study was to compare the effects of this combination with placebo on the side effects of laser-assisted hair removal. ⋯ Considering the better effect of lidocaine 7%-tetracaine 7% compared to placebo and its minimal side effects, we can use it before performing laser-assisted hair removal.

Postoperative pain is one of the most common complaints after elective laparoscopic cholecystectomy. The present study was aimed to evaluate the effect of paravertebral block using bupivacaine with/without fentanyl on postoperative pain and complications after laparoscopic cholecystectomy. ⋯ Adding fentanyl to bupivacaine in paravertebral block did not significantly improve the postoperative pain and complications after laparoscopic cholecystectomy. However, further studies are needed to be done.
