BACKGROUND Acceptance of a lower transfusion trigger in the perioperative period requires study of the effects of anesthetic depth on the tolerance to acute isovolemic anemia. Anesthetic agents with negative effects on the cardiovascular system may exert proportionately greater depressant effects on cardiac output response than on tissue oxygen demand, reducing tolerance to acute isovolemic ane...

BACKGROUND AND OBJECTIVES Caudal epidural anesthesia is the most popular regional anesthesia technique used in children. With advanced age, only the relative difficulty in localizing the sacral hiatus limits its use. However, in adults this technique has been widely used to control chronic pain by adjuvant use of fluoroscopy. Thus, the ability to locate the hiatus and define anatomical variatio...

Interscalene block is used for shoulder surgeries however it almost always results in phrenic nerve palsy1,2. Some anaesthesiologists have described careful ultrasound guided low volume (5mls only) of local anesthetic interscalene which does not cause hemidiaphragmatic paresis3. However we present to you a case where implied recently technique sparing involving combination oblique infraclavicul...

INTRODUCTION Few studies have evaluated the effectiveness of the Gow-Gates and Vazirani-Akinosi techniques in patients presenting with symptomatic irreversible pulpitis. Therefore, the purpose of this prospective, randomized study was to evaluate the anesthetic efficacy of the Gow-Gates and Vazirani-Akinosi techniques using 3.6 mL 2% lidocaine with 1:100,000 epinephrine in mandibular posterior ...

BACKGROUND Sphenopalatine ganglion block is used to treat headache and facial pain. There are transnasal, transoral and lateral approaches to establish the blockade. The transnasal application of topical anesthetic is the simplest and most common technique among the three. However, the diffusion of topical anesthetic to the ganglion is unpredictable and the blockade is not durable. OBJECTIVE ...

the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.

BACKGROUND Oral opioid analgesics have been used for management of peri- and postoperative analgesia in patients undergoing axillary dissection. The axillary region is a difficult zone to block and does not have a specific regional anesthesia technique published that offers its adequate blockade. METHODS After institutional review board approval, anatomic and radiological studies were conduct...

BACKGROUND AND OBJECTIVES Guillain-Barre syndrome during pregnancy is considered a rare neurological complication, and there is no consensus in literature for anesthetic management for cesarean section in such patients. The objective of this paper is to report the case of a pregnant woman with Guillain-Barre syndrome undergoing cesarean section. CASE REPORT Female patient, 22-year old, 35 wee...
