A common endpoint of general anesthetics is behavioral unresponsiveness, which is commonly associated with loss of consciousness. However, subjects can become disconnected from the environment while still having conscious experiences, as demonstrated by sleep states associated with dreaming. Among anesthetics, ketamine is remarkable in that it induces profound unresponsiveness, but subjects oft...

Post-anesthesia stridor due to laryngospasm, laryngeal edema, or any other organic cause is a life-threatening condition requiring immediate intervention. The very rare functional psychogenic following emergence from general anesthesia may sometimes mimic an cause, but it neither fatal nor require airway management. However, if the not diagnosed timely, lead unnecessary manipulation of airway, ...

emergence from general anesthesia can be associated with coughing, agitation, and hemodynamic disturbances. remifentanil may attenuate these responses. we have examined the effect of remifentanil on the hemodynamic response to the emergence from anesthesia and tracheal extubation. in a double-blind, randomized trial, we enrolled 50 adult patients undergoing abdominal surgery. all patients recei...

anisocoria during anesthesia is very rare, but may indicate life-threatening neurologic injuries and create tremendous condition. a 23-year-old male patient was anesthetized with fentanyl and propofol. thirty minutes after inducing anesthesia, unilateral mydriasis was detected. the duration of surgery was shortened for prompt evaluation of the pupils. at the end of the operation neither vision ...

Negative pressure pulmonary edema following tracheal extubation is an uncommon and life-threatening complication of patients undergoing endotracheal intubation and general anesthesia for surgical procedures. The common pattern in these cases is the occurrence of an episode of airway obstruction upon emergence from general anesthesia, usually caused by laryngospasm. Patients who are predisposed ...

A patient with remote cerebellar hemorrhage (RCH) who was presented at the authors' hospital with seizure and delayed emergence from anesthesia after loss of cerebrospinal fluid (CSF) through a dural tear during lumbar spine surgery is described. RCH is a rare and unpredictable complication after spinal surgery. Its most common clinical features are diminished consciousness, headache, and seizu...

BACKGROUND Maternal Mortality Surveillance has been conducted by the State of Michigan since 1950, and anesthesia-related maternal deaths were most recently reviewed for the years 1972-1984. METHODS Records for pregnancy-associated deaths between 1985 and 2003 were reviewed to identify 25 cases associated with a perioperative arrest or major anesthetic complication. Four obstetric anesthesiol...

The primary aim of this study was to investigate emergence delirium (ED) in service members, through the perceptions of active duty US Army anesthesia providers. The following perceptions were examined: (1) the extent and seriousness of ED in service members, (2) effects of ED on the safety of service members and operating room/postanesthesia care unit personnel, and (3) behaviors relevant to E...

UNLABELLED Emergence agitation is a frequent complication that can have serious consequences during recovery from general anesthesia. However, agitation has been poorly investigated in patients after craniotomy. In this prospective cohort study, adult patients were enrolled after elective craniotomy for brain tumor. The sedation-agitation scale was evaluated during the first 12 hours after surg...

background: tracheal intubation is used in general anesthesia and often leads to traumatization of the airway mucosa. these complications can cause postoperative morbidity. this study was designed to determine the effect of ketamine spraying on the endotracheal tube cuff on sore throat, cough, and hoarseness during the first 24 hours of the postoperative period. methods: 120 healthy women with ...
