Cataract sedation

Alina Yang, Ji Liu
The population of patients on left ventricular assist devices (LVADs) has increased significantly since the 1990s, and with it, need for non-cardiac elective surgeries. Presence of an LVAD or heart failure, however, can cause physicians to perceive these patients to be at prohibitively high risk for elective surgery. Nevertheless, as one of the most common causes of poor vision in the elderly, cataracts can significantly limit improvements in quality of life that a patient may have otherwise gained from LVAD support...

BACKGROUND: Dexmedetomidine is a potent and highly specific α2-adrenoreceptor agonist that induces sedative and analgesic effects over a short-term period. As a result of these benefits, dexmedetomidine may be a better alternative than other available drugs for keeping the patient's cognition state in an acceptable condition after outpatient ophthalmic surgeries. OBJECTIVES: This randomized study was conducted to compare the sedative effects of dexmedetomidine and remifentanil on the cognitive state of patients who have undergone cataract surgery...

Anesthesiological management of patients with Takotsubo syndrome (TTS) is a challenge of questions related to physiopathology, prognosis, and trigger causes. Relative rarity of this disease and lack of wide literature do not allow to state any negative or positive effect of the variety of drugs available for anesthesia. The authors report a case of a woman with a clear diagnosis of TTS and anxiety disorder, who underwent to cataract extractions at both eyes at two different times. Clinical management is described, from preoperative assessment until discharge of the patient...

BACKGROUND: Surgeries may trigger the stress response which leads to changes in blood glucose level, and studies suggest that different sedation and anesthesia methods have different effects on blood glucose level. The aim of this study was to investigate changes of blood glucose levels in diabetic patients and compare them in two sedation methods of propofol + fentanyl and midazolam + fentanyl. MATERIALS AND METHODS: Totally, 80 diabetic candidates for cataract surgery who had all the inclusion criteria, underwent cataract surgery using two methods of propofol (1 mg/kg/h) + fentanyl (2 μg/kg) (Group P) and midazolam (0...

BACKGROUND: Cataract is one of the most common surgical procedures in the elderly. In most cases, the elderly have cardiac ischemia or chronic coronary diseases, which would lead to more ischemic events during general anesthesia. Therefore, surgeons and anesthetists prefer regional aesthesia to the general one owing to its more advantages and less complications. OBJECTIVES: Therefore, this study aimed to compare topical method and retrobulbar block for pain intensity, patient's satisfaction, hemodynamic changes and intra and postoperative complications...
