Comparative StudyComparison of the Airtraq, Airway Scope, and disposable Macintosh laryngoscope blade.
The present study was performed to 1. compare usefulness of the Airtraq (ATQ) and the Airway Scope (AWS) with the Macintosh laryngoscope (MAC), 2. compare usefulness of the ATQ with the AWS, 3. compare usefulness of the AWS with the tip of the blade under the epiglottis as recommended by the manufacturer (AWS-Miller) and the AWS with the tip of the blade in the vallecula as the MAC (AWS-MAC), in tracheal intubation by expert anesthesiologists. ⋯ The MAC and ATQ were better than the AWS-Miller for patients with easy intubation, while the ATQ was better than the MAC for difficult intubation when the expert anesthesiologists did the intubation.

Case ReportsAsymptomatic epiglottic cyst: a rare cause of unanticipated difficult intubation.
Cysts of epiglottis are rare. Following induction of anesthesia, asymptomatic cysts may lead to unanticipated difficulty in ventilation or intubation or both and can be potentially life threatening in such situations.

Randomized Controlled Trial Comparative StudyComparison of local anesthetic effects of tramadol and lidocaine used subcutaneously in minor surgeries with local anesthesia.
In this study, the local anesthetic and post-operative analgesic effects of tramadol were compared to those of lidocaine in minor surgeries under local anesthesia. ⋯ Tramadol 2 mg/kg has local anesthetic and post-operative analgesic effect equal to lidocaine 1 mg/kg in minor surgeries performed subcutaneously. Therefore, we concluded that tramadol can be used as an alternative drug to lidocaine in local anesthesia and has the ability to decrease the demand for post operative analgesics.

Randomized Controlled TrialProspective, randomized controlled study to assess the role of dexmedetomidine in patients with supratentorial tumors undergoing craniotomy under general anesthesia.
Preliminary data on the perioperative use of dexmedetomidine in patients undergoing craniotomy for brain tumor under general anesthesia indicate that the intraoperative administration of dexmedetomidine is opioid-sparing, results in less need for antihypertensive medication, and may offer greater hemodynamic stability at incision and emergence. Dexmedetomidine, alpha 2 adrenoceptor agonist, is used as adjuvant to anesthetic agents. Relatively recent studies have shown that dexmedetomidine is able to decrease circulating plasma norepinephrine and epinephrine concentration in approximately 50%, decreases brain blood flow by directly acting on post-synaptic alpha 2 receptors, decreases CSF pressure without ischemic suffering and effectively decreases brain metabolism and intracranial pressure and also, able to decrease injury caused by focal ischemia. ⋯ Continuous intraoperative infusion of dexmedetomidine during craniotomy for supratentorial tumors under general anesthesia maintained the hemodynamic stability, reduced sevoflurane and fentanyl requirements, decreased intracranial pressure, and improved significantly the outcomes.

Randomized Controlled TrialThe importance of training for ultrasound guidance in central vein catheterization.
To review the complication and success rates associated with CVC placement in patients undergoing cardiovascular surgery depending on the technique utilized and the degree of ultrasound experience of the anesthesia provider. ⋯ With adequate US training, the complications from CVC including carotid artery puncture and pneumothorax can be significantly reduced.
