RESUMO
The preoperative fast is an unpleasant preoperative experience that may be alleviated by allowing children to drink clear fluids. This study was undertaken to ascertain whether ingestion of clear fluids would influence the volume and pH of gastric contents. We studied prospectively 50 children [aging from 5 - 12 years] undergoing elective surgery. Fifty percent of the patients were allowed to ingest unlimited clear fluids until 2 hrs before surgery [study group]. The other 50% were instructed, to remain fasting from midnight until before surgery [control group]. There were no significant differences between both groups in respect of the volume of gastric content aspirated and the median pH of the gastric contents. Children who ingested clear fluids 2 hr before surgery did not have an increased incidence of [at risk] gastric contents. No adverse intraoperative and postoperative events were noted in both groups. Patients in the study group experienced less thirst before induction of anaesthesia than those in the control group. Patient hunger at the time of surgery was unaffected by ingestion of clear fluids

This study was conducted on 30 patients of ASA class I or II, they were divided into two groups. The first group consisted of 15 patients receiving sodium nitroprusside alone as hypotensive drug during general anesthesia, the second group consisted of 15 patients receiving a mixture of sodium nitroprusside and clonidine as hypotensive drug during general anesthesia. Clinical and laboratory results showed that clonidine nitroprusside mixture [CNP] is as effective as sodium nitroprusside [SNP] for induction of hypotension during general anesthesia. In addition, the mixture of clonidine- sodium nitroprusside has the advantage of decreasing the dose requirement of SNP with more hemodynamic stability during and after infusion together with reduced potential of cyanide toxicity
