The effects of preoperativefasting on plasma glucose and gastric emptying was studied in 62 infants aged less than three months after a feed of either breast milk or an infant milk formula. Prior to induction of anaesthesia no infant was hypoglycaemic, defined as plasma glucose < 2.2 mmolll. Five per cent of infants had a significant volume of residual gastric contents. The mean intraoperative plasma glucose levels rose significantly and this was not influenced by the use of intravenous H artmann's solution or low dose opioids. Infants in this age group tolerate three-to four-hour preoperative fasts well as no infant became hypoglycaemic intraoperatively. They demonstrate a hyperglycaemic response to the stress of anaesthesia and surgery, and may not need routine intraoperative glucose supplements although plasma glucose should still be monitored.
Endoscopic obliteration of the eustachian tube using a double seal technique is a simple, safe and effective procedure in the treatment of a refractory cerebrospinal fluid leak.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
