Randomized Controlled Trial Comparative StudyInfluence of intraoperative sevoflurane or desflurane on postoperative sore throat: a prospective randomized study.
Tracheal intubation for general anesthesia causes postoperative sore throat. The purpose of this study was to evaluate the effect of sevoflurane and desflurane on prevalence of postoperative sore throat in patients after general anesthesia. ⋯ We have shown that sevoflurane was associated with less frequent sore throat than desflurane in patients undergoing orthopedic lower extremity surgery.

Randomized Controlled TrialThe analgesic efficacy and duration of lidocaine on vascular pain induced by hypertonic saline infusion: a double-blinded, randomized control trial.
To determine the analgesic efficacy and analgesic duration of lidocaine 20 mg and 40 mg on eliminating the vascular pain associated with hypertonic saline infusion. ⋯ A single bolus of Lidocaine was effective in eliminating the pain induced by hypertonic saline infusion, but just for a short period of time. Lidocaine (without venous occlusion) only provides a short analgesic duration for local vein.

Randomized Controlled TrialLow-dose dexmedetomidine provides hemodynamics stabilization during emergence and recovery from general anesthesia in patients undergoing carotid endarterectomy: a randomized double-blind, placebo-controlled trial.
Carotid artery stenosis is a major risk factor for ischemic stroke. Carotid endarterectomy protects patients with severe atherosclerotic carotid artery stenosis against stroke. In such patients, arterial blood pressure is often difficult to control and perioperative hemodynamic instability is associated with high morbidity and mortality after carotid endarterectomy. We performed a randomized double-blind placebo-control trial to evaluate the effects of low-dose dexmedetomidine on hemodynamic stability during the emergence and the recovery phases of general anesthesia in patients undergoing carotid endarterectomy. ⋯ Low-dose dexmedetomidine improves hemodynamic stability during emergence and recovery from general anesthesia in patients receiving carotid endarterectomy.

Randomized Controlled Trial Comparative StudyLocal anesthetic spread into the paravertebral space with two types of quadratus lumborum blocks: a crossover volunteer study.
Previous work showed that 20 mL of local anesthetic (LA) did not spread into the paravertebral space (PVS) via the intramuscular quadratus lumborum block (QLBi). If spread of LA into the PVS can be achieved by increasing the total LA volume, QLBi can be more effective. We hypothesized that a larger volume of LA for the QLBi would spread into the PVS. ⋯ LA administered by the QLB2 spreads into the PVS of T10-T12, resulting in lower and lateral abdominal sensory loss. In contrast, LA administered by the QLBi does not spread into the PVS and results in only lateral abdominal sensory loss.

Randomized Controlled Trial Comparative StudyThree versus five lumbar paravertebral injections for inguinal hernia repair in the elderly: a randomized double-blind clinical trial.
The objective of the study was to compare three nerve stimulator-guided paravertebral injections versus five injections for elderly patients undergoing inguinal hernia repair in terms of the amount of intraoperative fentanyl and propofol consumption and conversion to general anesthesia. The secondary objective was postoperative pain. ⋯ The five PVB injection technique is more suitable as a sole anesthetic technique for elderly patients undergoing herniorrhaphy, since it required less intraoperative supplemental analgesia and provided lower postoperative pain scores compared to the three PVB injection technique.
