Evaluating the preventive effect of metoclopramide and aminophylline on pain after deep vitrectomy.

Background: Deep vitrectomy is one of the most frequently performed ophthalmic procedures. Postoperative pain is a common complaint among patients. Consequently, we investigated whether metoclopramide and aminophylline could decrease pain intensity following deep vitrectomy.

Tracheal Sound Analysis for Automatic Detection of Respiratory Depression in Adult Patients during Cataract Surgery under Sedation.

Background: Tracheal sound analysis is a simple way to study the abnormalities of upper airway like airway obstruction. Hence, it may be an effective method for detection of alveolar hypoventilation and respiratory depression. This study was designed to investigate the importance of tracheal sound analysis to detect respiratory depression during cataract surgery under sedation.

Changes in blood glucose level during and after light sedations using propofol-fentanyl and midazolam-fentanyl in diabetic patients who underwent cataract surgery.

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.

Effect of ketamine as an adjuvant in ultrasound-guided supraclavicular brachial plexus block: A double-blind randomized clinical trial study.

Background: Supraclavicular brachial plexus block is one of the most effective anesthetic procedures in operations for the upper extremity. Ketamine has been reported to enhance the analgesic effects of local anesthetics. We have conducted this study to assess whether coadministration of ketamine can prolong the local analgesic effect of lidocaine in the supraclavicular brachial plexus block for patients undergoing elective upper extremity surgery.
