Effects of lorazepam on oxygen saturation before cardiac surgery.

چکیده
We have studied patients presenting for coronary artery bypass surgery on two nights before surgery. Oxygen saturation during a night when the patient received no night sedation was compared with the night before surgery, when lorazepam 3-4 mg was given. There was no difference between the two nights when the total time at oxygen saturations less than 90% were compared, but the minimum oxygen saturation value when the patient received lorazepam was significantly smaller. No patient had significant sleep apnoea.

Background: Pulseoximetry is widely used in the critical care setting, currently used to guide therapeutic interventions. Few studies have evaluated the accuracy of SPO2 (puls-eoximetry oxygen saturation) in intensive care unit after cardiac surgery. Our objective was to compare pulseoximetry with arterial oxygen saturation (SaO2) during clinical routine in such patients, and to examine the eff...

INTRODUCTION Postoperative delirium is an important problem in patients undergoing major surgery. Cerebral oximetry is a non-invasive method to detect imbalances in the cerebral oxygen supply/demand-ratio. Low preoperative cerebral oxygen saturation (ScO₂) levels have been associated with postoperative delirium in non-cardiac surgery patients. The present prospective observational study determi...

Background: Hand grip strength (HGS) is a reliable indicator of peripheral muscle strength. Although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (CAD) patients, exploring the relationship between HGS and myocardial oxygen consumption (MVO2) index. The current study aimed to evaluate the interaction between HGS and MVO...

Lorazepam is widely used preoperatively for anxiolysis/sedation. Lorazepam has been reported to decrease the incidence of chemotherapy induce vomiting. However, the effect of lorazepam on postoperative vomiting has not been studied. The purpose of this study was to evaluate the effect of preoperative lorazepam on postoperative vomiting. This study is a semi-experimental survey about the antieme...
