General anaesthesia for ophthalmic surgery

Publication date: Available online 25 November 2019Source: Anaesthesia &Intensive Care MedicineAuthor(s): Stuart Young, Aravind BasavarajuAbstractThe majority of ophthalmic surgeries are performed as day cases under topical or regional anaesthesia with or without intravenous sedation. However, general anaesthesia is necessary in certain circumstances e.g. local anaesthetic allergy or patients who are unable to cooperate or to lie flat or still. Patients for ophthalmic surgery are frequently elderly with multiple comorbidities, such as diabetes and hypertension. Patients with rare genetic syndromes may present for eye surgery. Therefore adequate preoperative evaluation and preparation will minimize perioperative complications. The goals of general anaesthesia are smooth induction and emergence, with stable intra-ocular pressure (IOP) and akinesia of the globe. These can be achieved with a combination of intravenous and inhalational agents with or without muscle relaxants and opiates. Use of the laryngeal mask airway has the advantage of causing a smaller rise in IOP on insertion and less coughing on emergence. Total intravenous anaesthesia with propofol and remifentanil has the advantages of causing less postoperative nausea and vomiting (PONV), reduced stress response to airway intervention, rapid recovery and smooth emergence. Some eye procedures require special consideration, for example, strabismus and vitreoretinal surgery involves traction of the rectus muscles produ...

CONCLUSIONS: Awareness of possible repercussions of the celiac trunk stenosis to peripancreatic arteries should be elevated. Restoration of physiological blood flow by removing pathologic anatomy should be performed. Since there is no correlation between the size of a visceral aneurysm and the risk of rupture, having a high postrupture mortality, pancreaticoduodenal artery aneurysms should be treated even if asymptomatic. Surgical treatment remains the mainstay treatment of the Dunbar syndrome complicated by visceral aneurysms. PMID: 31961777 [PubMed - as supplied by publisher]

Dulin, Elizaveta A. KlimanovaAbstractWith an exception of few reports, the plasma concentration of ouabain and marinobufagenin, mostly studied cardiotonic steroids (CTS) assessed by immunoassay techniques, is less than 1 nM. During the last 3 decades, the implication of these endogenous CTS in the pathogenesis of hypertension and other volume-expanded disorders is widely disputed. The threshold for inhibition by CTS of human an...

Jie, S.U.N. Xuan, X.U. BiaoAbstract and KeywordsHypertension (HT) is the most common public-health challenge and shows a high incidence around the world. Cardiovascular diseases are the leading cause of mortality and morbidity among the elderly (age> 65 years) in the United States. Now, there is widespread acceptance of the causal link between HT and acute myocardial infarction (MI). This is the first data-mining study to id...

We report a case of malignant non-neural-type GCT in the lungs.A 77-year-old woman felt chest discomfort and dyspnea in July 2019. She had never smoked and had no medical history other than hypertension and diabetes mellitus.She was initially evaluated at a local hospital. Flexible bronchoscopy showed total occlusion of the right main bronchus by a mass-like lesion. Biopsy of the mass lesion revealed chronic inflammation. The patient visited for re-evaluation in September 2019. Rigid bronchoscopy showed worsening of the total obstruction of the right main bronchus by a tumor mass, such that the carina was not visible. Addi...

Authors: Akagi S, Miki T, Sando Y, Fujii N, Sarashina T, Nakamura K, Ito H Abstract Chronic-active Epstein-Barr virus infection (CAEBV) is a rare disease that can lead to pulmonary arterial hypertension (PAH). However, the treatment for CAEBV-associated PAH has not been established. We discuss a case of improved pulmonary hypertension after chemotherapy in a patient with CAEBV-associated PAH. A 44-year old man was admitted to our hospital because of an abnormal electrocardiogram and liver dysfunction detected by annual medical examination. Echocardiography showed a dilated right ventricle and an estimated right ven...

We report the case of a 33-year-old woman with no history of coronary risk factors or chest pain who experienced intermittent chest pain at rest for several minutes from 2 PM. At 8 AM the next day, chest pain recurred and persisted for about 1 hour. She was transported to our hospital by ambulance, where electrocardiogram showed ST-elevation in the precordial leads, and blood tests showed elevation of cardiac markers. She was diagnosed with ST-elevation myocardial infarction. Because she was a young woman without any risk factors, coronary spastic angina was suspected. Coronary angiography without intracoronary nitrate adm...
