In this article, we review the methods of anaesthesia commonly used in ophthalmology in Singapore. These include topical, local, regional and general anaesthesia. Topical and local anaesthesia is adequate for most outpatient procedures. The most common form of regional anaesthesia in Singapore is still retrobulbar anaesthesia. General anaesthesia is used in children and when more extensive proc...

The risk of life-threatening complications during induction of anesthesia in patients with anterior mediastinal mass is well recognized. Maintenance of spontaneous ventilation during anesthesia is an accepted standard goal in all published reports. However, the decision to paralyze the patient, which is really needed in most surgical procedures, is still a challenging event. In this study, “man...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

An objective measure of the hypnotic component of general anaesthesia has been sought

Background and Objective: The low quality of recovery after anesthesia has prolonged postoperative hospitalization time. The purpose of this study was to compare the effect of general anesthesia and spinal anesthesia on quality of recovery after abdominal hysterectomy. Materials and Methods: This study is a clinical trial on 100 women 35 to 70 years with ASA class I, II who candidate to abdomi...

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 ...

Children, similar to adults, are required to fast before general anesthesia in order to reduce  the volume and acidity of stomach contents. It is thought that NPO regulations reduce the risk of regurgitation and aspiration of gastric contents during surgery. Recent developments have encouraged a shift from the standard 'nil by mouth from midnight' fasting policy to more relaxed regimens. Preope...
