Randomized Controlled Trial Clinical Trial
[The effect of preoperative oral fluid intake on the volume and pH of gastric contents in elective surgical patients--a comparison of tea with apple juice].
This study aimed to investigate the effect of 150 ml of either tea or apple juice on the volume and pH of gastric contents in 40 elective surgical patients, ranging in age from 18 to 70 years. They were given diazepam 5 approximately 10 mg and roxatidine 75 mg orally 2 hours before the start of isoflurane anesthesia or modified neuroleptic anesthesia. ⋯ There was a significant difference in the gastric volume between the two groups (P < 0.05), while no significant difference in gastric pH was observed. This result suggests that apple juice is not appropriate as preoperative drink because apple juice increases gastric contents, and may cause aspiration pneumonia.

Randomized Controlled Trial Clinical Trial
[Skillfulness is essential to improve venipuncture pain in combination with lidocaine containing adhesive tape].
We evaluated the effect of lidocaine containing adhesive tape (LT) on the venipuncture pain by using visual analogue scale (VAS). Patients were assigned prospectively to a control (65 cases) group and a LT (80 cases) group weekly. LT was applied 30 min before the scheduled entry into the operating room. ⋯ Smooth venipuncture was performed in 91% of those in expert group. However only 71% of venipuncture was done smoothly in the novice group. We conclude that skillful venipuncture in combination with LT is essential to reduce the venipuncture pain.

Randomized Controlled Trial Clinical Trial
[Possibility of rice porridge for preoperative feeding in children].
To determine the effect of rice porridge feeding before elective surgery on preoperative gastric fluid pH, volume and starvation, a prospective study was undertaken in pediatric patients. Twenty healthy children ranged in age from 5 to 12 years were allocated randomly to either a fasted or rice porridge group. The children of fasted group (control group) were allowed to take solid food until midnight before the operation. ⋯ There were no significant differences between the two groups concerning the gastric fluid volume and pH. The patient of the study group complained of less hunger. Preoperative rice porridge feeding is a possible preoperative feeding for pediatric patients.

Randomized Controlled Trial Clinical Trial
[The effects of preoperative drinking and H2 blocker on gastric acid secretion].
We studied the effects of preoperative drinking and H2 blocker on gastric acid secretion in 63 patients (ASA I-II, > 18yrs) scheduled for afternoon surgery. Group A (n = 20), as a control, was not permitted to eat and drink from 9 pm, the day before surgery, and was then given 500 ml of maintainance fluid before anesthesia. Group B (n = 20) fasted from 9 pm the day before surgery, and was allowed to drink clear fluids until 2hs before anesthesia. ⋯ The dilution of gastric acid by the ingested fluid was not observed. We conclude that preoperative drinking does not affect gastric contents in elective operative patients. To reduce the risk of developing aspiration pneumonia, we recommend that every patient should receive an oral H2 blocker.

Randomized Controlled Trial Comparative Study Clinical Trial
[The effects of sevoflurane and isoflurane on hepatic blood flow in man].
The influences of sevoflurane and isoflurane on hepatic blood flow (HBF) in man were investigated employing the method of continuous infusion of indocyanine green. HBF and cardiac output (CO) were measured in patients before and after induction of anesthesia with thiamylal, fentanyl, and N2O, and again during isoflurane (n = 9) or sevoflurane (n = 8) anesthesia before the start of surgery. ⋯ Although CO decreased similarly in both groups during anesthesia, the HBF/CO ratio in isoflurane group increased significantly, and the ratio in sevoflurane group did not change significantly. We conclude that whereas isoflurane increases HBF, sevoflurane does not change it in anesthetized patients.
