Background: Anesthetic dreaming and anesthesia awareness are well distinct phenomena. Although the incidence of intraoperative awareness is more common among patients who reported a dream after surgery, the exact correlation between the two phenomena remains an unsolved rebus. The main purpose of this study was to investigate anesthetic dreaming, anesthesia awareness and psychological consequences eventually occurred under deep sedation. Intraoperative dreaming experiences were correlated with dream features in natural sleep...

BACKGROUND: Increased incidence of intraoperative awareness was reported in critically ill patients during major operations, particularly under total intravenous (TIVA) or endotracheal general anesthesia (ETGA). However, the incidence and effect of anesthesia techniques on awareness in generally healthy, non-critically ill patients during operations have yet to receive significant attention. METHODS AND RESULTS: This retrospective matched case-control study was conducted between January 2009 to December 2014...

INTRODUCTION: We report a 39-year-old male patient with a fracture of the right acetabulum undergoing open reduction and internal fixation with a plate under general anesthesia. At closure, the surgeons injected 0.75% ropivacaine into the subcutaneous tissue of the incision wound for postoperative analgesia. Soon after injection, subcutaneous emphysema at the injection site and a sudden decrease in end-tidal CO2 tension with crude oscillatory ripples during the alveolar plateau phase were observed...

BACKGROUND: Spinal radiculomedullary artery aneurysms are extremely rare. Treatment should be tailored to clinical presentation, distal aneurysm flow, and lesion anatomical features. When a surgical occlusion is planned, it is necessary to evaluate whether intraoperative monitoring (IOM) should be considered as an indispensable tool to prevent potential spinal cord ischemia. METHODS: We present a patient with symptoms and signs of spinal subarachnoid hemorrhage resulting from the rupture of a T4 anterior radiculomedullary aneurysm who underwent open surgical treatment under motor evoked potential (MEP) monitoring...

Percutaneous endoscopic surgery for the lumbar spine has become established in the last decade. It requires only an 8 mm skin incision, causes minimal damage to the paravertebral muscles, and can be performed under local anesthesia. With the advent of improved equipment, in particular the high-speed surgical drill, the indications for percutaneous endoscopic surgery have expanded to include lumbar spinal canal stenosis. Transforaminal percutaneous endoscopic discectomy has been used to treat intervertebral stenosis...

Some surgical procedures performed under moderate and sometimes extreme positions expose patients to nonphysiological changes. Especially, the manipulations of a patient in prone and lateral decubitus position might increase complications. Anesthesia mumps has been reported as one of these complications. It has been found to be rare but known entity associated with patients of all age groups and all surgical positions. We herein describe an early noticed acute case of unilateral anesthesia mumps that developed after endotracheal intubation in prone position in a 54-year-old female...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 years earlier. A 50-year-old man was admitted to the emergency room for an exposed substance in the lower eyelid area of the left eye, which began as a palpable hard nodule a week earlier...

INTRODUCTION: Postoperative sore throat is listed from the top as patients' most undesirable outcome in the postoperative period. It is believed to originate from mucosal dehydration or edema, tracheal ischemia secondary to the pressure of endotracheal tube cuffs, aggressive oropharyngeal suctioning, and mucosal erosion from friction between delicate tissues and the endotracheal tube. Even if the problem was indicated in many literatures, it has never been studied in our country. The study aimed to assess prevalence and factors associated with postoperative sore throat among patients who were operated under general anesthesia with endotracheal intubation...

REVIEW
Mathew Albert Wei Ting Lim, Gelsomina Lucia Borromeo
General anesthesia is commonly used to facilitate dental treatment in patients with anxiety or challenging behavior, many of whom are children or patients with special needs. When performing procedures under general anesthesia, dental surgeons must perform a thorough pre-operative assessment, as well as ensure that the patients are aware of the potential risks and that informed consent has been obtained. Such precautions ensure optimal patient management and reduce the frequency of morbidities associated with this form of sedation...

Hemangioma is the most common benign tumor of a vascular origin, and is characterized by the abnormal proliferation of blood vessels. Intramuscular hemangioma (IMH) usually involves the skeletal muscles of the trunk or limbs, but rarely occurs in the head and neck region. This case report presents a patient with IMH showing multiple phleboliths in the buccal cheek. A 13-year-old boy was referred for the evaluation and management of painful swelling of the left cheek that had gradually increased in size over a 6 year duration...

T Apard, G Candelier
Ultrasound-guided surgery is a new trend stemming from the introduction of high-frequency linear probes and better quality screens. Surgical treatment of carpal tunnel syndrome is increasingly being performed under ultrasound guidance. Knowledge of musculoskeletal ultrasonography is obviously mandatory. Several types of cutting instruments (miniature knife, Gigli saw or hook) and surgical approaches (wrist or palm) have been described. Ultrasonography allows the wide-awake and local anesthesia with no tourniquet (WALANT) technique to be used in the context of ambulatory patient care...

BACKGROUND: In light of the increasing number of radiologic interventions performed under general anesthesia, the effects of contrast media (CM) on circulation and organ perfusion are of paramount importance. The objectives of this study were to systematically quantify effects on blood pressure, heart rate, and kidney function following intravenous administration of nonionic CM with normal and low osmolality. METHODS: In this controlled, double-blinded phase IV clinical trial, 40 consecutive patients were randomly assigned to receive repeated measures of either low-osmolar iopromide or iso-osmolar iodixanol...

We report a case of limb-shaking transient ischemic attack (TIA) caused by a dissection of the middle cerebral artery (MCA) following lung surgery under general anesthesia. An 81-year-old male patient who underwent lobectomy for lung cancer suddenly developed transient shaking movements of the neck and the left upper distal limb on postoperative day 1. On the basis of the double-barrel appearance of the right M1 segment of the MCA, a diagnosis of MCA dissection was made. Physicians should be aware that limb-shaking TIA is sometimes caused by MCA dissection and could be precipitated by any condition, including lung surgery under general anesthesia...

General anesthesia (GA) is a reversible drug-induced state of altered arousal required for more than 60,000 surgical procedures each day in the United States alone. Sedation and unconsciousness under GA are associated with stereotyped electrophysiological oscillations that are thought to reflect profound disruptions of activity in neuronal circuits that mediate awareness and cognition. Computational models make specific predictions about the role of the cortex and thalamus in these oscillations. In this paper, we provide in vivo evidence in rats that alpha oscillations (10-15 Hz) induced by the commonly used anesthetic drug propofol are synchronized between the thalamus and the medial prefrontal cortex...

INTRODUCTION: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors. They are surgically curable but can be lethal if remain undiagnosed. We report a patient earlier diagnosed with malignant hyperthermia but later found to have pheochromocytoma on autopsy. CASE REPORT: After a preprocedural pain block for elective right shoulder arthroscopy, a 53-year-old hypertensive white man developed chest pain. In the operating room, he had increased blood pressure...

Deepak Singla, Mishu Mangla
CONTEXT: Awareness under anesthesia is a rare but extremely unpleasant phenomenon. There are very few studies in the developing world and none from rural areas where incidence of intraoperative awareness may be higher due to increased patient load, limited patient knowledge and lack of trained hospital staff, reliance on older, cheaper but less effective drugs, and lack of proper equipment both for providing anesthesia, as well as monitoring the patient. AIMS: To assess the incidence of intraoperative awareness during general anesthesia among patients in rural India and any factors associated with the same...
