patients referred to amir-alam hospital, affiliated to tehran university of medical sciences, were given anesthesia through two ways inhalationally (by means of sodium thiopenton) and intravenously (halothane+n2o). in this article, we discuss the results obtained from the patients' bronchoscopies. according to our study, inhalational anesthesia have had desirable effects since halothane ha...

Upon inducting general anesthesia in the operating room, we have observed a prompt increase in the bispectral index (BIS) after the intravenous injection of suxamethonium. We hypothesized that the cause of this BIS increase is muscle hyperactivity owing to fasciculation. However, no reports have been published regarding this abrupt increase in the BIS upon the induction of general anesthesia by...

Background: Intracranial pressure (ICP) control is one of the anesthesiologist challenges in craniosynostosis repair surgery, especially in multiple sutures involvement. The aim of this study was comparing the effect of two anesthesia methods including inhalation with hyperventilation and total intravenous anesthesia (TIVA) on ICP control and surgeon satisfaction in pediatrics with craniosynost...

Background and Objective: Optimal pain management for esophagectomy facilitates prevention of postoperative complications such as pneumonia, but also chronic pain. Historically, multimodal intravenous analgesia was employed. In the last decades, regional anesthesia including epidural paravertebral is frequently used. this narrative review, we provide a comprehensive overview available evidence ...

background the involved neurotransmitter pathways in the postoperative shivering (pos) are poorly understood. recently, 5-hydroxytryptamine 3 (5-ht3) receptor antagonists have been reported to prevent pos. we investigated the effect of ondansetron, a 5-ht3 antagonist that is used to treat postoperative nausea and vomiting, on shivering. objectives this study aimed to compare the efficacy of ond...

PURPOSE To make an objective controlled comparison of pain tolerance in transrectal ultrasound-guided prostatic biopsy using intrarectal topic anesthesia, injectable periprostatic anesthesia, or low-dose intravenous sedation. MATERIALS AND METHODS One hundred and sixty patients were randomized into 4 groups: group I, intrarectal application of 2% lidocaine gel; group II, periprostatic anesthe...

BACKGROUND Postoperative shivering is a major problem in children undergoing general anesthesia. OBJECTIVES The aim of the present study was to investigate the role of low-dose intravenous ketamine for prevention of shivering after induction of general anesthesia in children who had undergone tonsillectomy. PATIENTS AND METHODS This was a randomized, double-blinded, placebo-controlled trial...

Autistic children are very difficult to manage in the hospital setting because they react badly to any change in routine. We describe a case of 10-year-old male patient with severe autism undergoing orchidopexy and circumcision. Following premedication, anesthesia was induced with remifentanil, propofol, atracurium, and maintained with total intravenous anesthesia (propofol and remifentanil). T...

Introduction. The aim of this study was to evaluate two measures in a cognitive examination: psychomotor function and the perception of time (PT) in patients after intravenous anesthesia for endoscopic procedures. Material and Methods. We tested 23 anesthetized patients (Anesthesia Group, AG) and 17 not anesthetized patients (Control Group, CG). The Dufour Cross-Shaped Apparatus (DA) was used t...

PURPOSE OF REVIEW The purpose of this review is to discuss the risk factors associated with laryngospasm and the techniques used for prevention and treatment. We also summarize the prevention and treatment modalities in organized algorithms. RECENT FINDINGS According to recent endoscopic studies, laryngospasm is always complete, thus airway management and intravenous therapy are indicated. Pa...
