Randomized Controlled Trial
Onset Time of 2% Lidocaine and 0.5% Bupivacaine Mixture versus 0.5% Bupivacaine Alone using Ultrasound and Double Nerve Stimulation for Infraclavicular Brachial Plexus Anesthesia in ESRD Patients Undergoing Arteriovenous Fistula Creation.
To reduce the onset of 0.5% bupivacaine by adding 2% lidocaine with 0.5% bupivacaine for ultrasound-guided and double stimulation technique at musculocutaneous and radial nerve for infraclavicular brachial plexus block. ⋯ Mixing 2% lidocaine with 0.5% bupivacaine to the final concentration of 0.67%for lidocaine and 0.33% for bupivacaine does not reduce the onset of ultrasound-guided infraclavicular brachial plexus block.

Target Controlled Infusion versus Sevoflurane/Desflurane Anesthesia for Laparoscopic Cholecystectomy: Comparison Postoperative Nausea/Vomiting and Extubation Time.
Target-controlled infusion (TCI) systems have been developed from manually controlled infusion systems and have rapidly increased in popularity, especially in laparoscopic surgery. Propofol is claimed to decrease nausea and vomiting. ⋯ Laparoscopic cholecystectomy under propofol with TCI is one option of anesthetic technique with a significantly lower incidence of PONV compared with both sevoflurane and desflurane otherwise there is no statistical difference in the extubation time. Propofol-TCI technique is suggested for laparoscopic and ambulatory surgery.

Efficacy and Safety of Single Botulinum Toxin Type A (Botox®) Injection for Relief of Upper Trapezius Myofascial Trigger Point: A Randomized, Double-Blind, Placebo-Controlled Study.
Botulinum toxin injection has been applied for pain relief in various chronic pain syndromes. Recently, systematic review studies reported inconclusive effects of Botulinum toxin in myofascial pain management. The present study aimed to demonstrate the efficacy and safety of Botulinum toxin type A (BTxA) (Botox®) injection for pain reduction in myofascial trigger point (MTrP) of the upper trapezius muscle. ⋯ The efficacy in VAS reduction of a single 20 IU of Botulinum toxin type A (Botox®) injection was not different from 0.9% NaCl for myofascial trigger point at the upper trapezius muscle. However Botulinum toxin type A (Botox®) showed statistically significant more increased in pressure pain threshold at 6-week after injection without severe adverse effects.

The Effects of Single-Dose Preoperative Intravenous Dexamethasone on Clinical Outcome after Laparoscopic Cholecystectomy.
Laparoscopic cholecystectomy is one of the most common procedures in surgery. Post-operative pain and post- operative nausea and vomiting (PON) are frequently events after laparoscopic cholecystectomy and cause distress to patients. Dexamethasones are known for analgesic, anti-inflammatory, immune-modulating and anti-emetic effects. Therefore, preoperative dexamethasone administration may reduce postoperative pain and postoperative nausea vomiting after laparoscopic cholecystectomy. ⋯ Single-dose preoperative dexamethasone 8 mg 60-90 minute before induction of anesthesia improved clinical outcome in terms of significantly less nausea, vomiting, pain at first 6 hours and less inflammatory response after laparoscopic cholecystectomy compared to placebo. The preoperative dexamethasone should be used as routine in patients undergoing laparoscopic cholecystectomy.

Direct Field Block with 40 ML of 0.125% Bupivacaine in Conjunction with Intrathecal Morphine for Analgesia after Cesarean Section: A Randomized Controlled Trial.
To investigate the effect of direct field block with 40 ml of 0.125% bupivacaine on the top of intrathecal morphine on postoperative pain free period. ⋯ Direct field block with 40 ml of 0.125% bupivacaine in conjunction with intrathecal morphine for cesarean section did not increase pain free period or decrease morphine consumption.
