Gastric Fluid Volume Change After Oral Rehydration Solution Intake in Morbidly Obese and Normal Controls: A Magnetic Resonance Imaging-Based Analysis.

Background: Although preoperative fluid intake 2 hours before anesthesia is generally considered safe, there are concerns about delayed gastric emptying in obese subjects. In this study, the gastric fluid volume (GFV) change in morbidly obese subjects was investigated after ingesting an oral rehydration solution (ORS) and then compared with that in nonobese subjects.

Methods: GFV change over time after the ingestion of 500 mL of ORS containing 2.

[Anesthetic management of MIDCAB with high dose diltiazem].

Precise management of blood pressure and heart rate is required during minimally invasive direct coronary artery bypass (MIDCAB). Previously, low dose diltiazem and beta-blokers have been employed for control of circulation during this procedure, but we report 2 patients whose blood pressure and heart rate were managed during MIDCAB by high-dose diltiazem. In both patients, anesthesia was induced with propofol, vecuronium and fentanyl, and maintained by continuous infusion of propofol and inhalation of oxygen and nitrous oxide.

[Two cases of intraoperative cerebral hemorrhage caused by undiagnosed metastatic brain tumors].

The authors report two cases of intraoperative cerebral hemorrhage caused by metastatic brain tumors. Delayed recovery from general anesthesia and neurological deficit were found in these patients. Brain CT in case 1 showed bilateral subdural hemorrhage and parenchymal massive hemorrhage in case 2.
