Randomized Controlled Trial Clinical Trial
Ingestion of clear fluids is safe for adolescents up to 3 h before anaesthesia.
We have studied the effect of ingestion of unlimited clear fluids by adolescents up to 3 h before anaesthesia to determine the effect this fluid ingestion would have on thirst, hunger and gastric contents at induction of anaesthesia. We studied prospectively 152 adolescents (ages 13-19 yr) undergoing elective surgery. Fifty percent of the patients had nothing by mouth after midnight. ⋯ GV, GpH and subject hunger were unaffected by ingestion of clear fluids. Subject thirst was reduced by clear fluids. It is concluded that unlimited clear fluid ingestion by healthy adolescents up to 3 h before operation decreases thirst and does not affect gastric contents.

Randomized Controlled Trial Comparative Study Clinical Trial
Modification of pain on injection of propofol--a comparison between lignocaine and procaine.
Pain on injection of propofol was assessed in a controlled, randomised study of 273 patients. They received either lignocaine 10 mg, procaine 10 mg or isotonic saline 0.5 ml, 15 seconds before the injection of propofol into a vein on the back of the hand. The incidence of pain on injection in the control group (51%) was comparable with other studies. Lignocaine and procaine both significantly reduced the pain (35% and 34% respectively, p less than 0.05) but there was no statistical difference between these two groups.

Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of obstetrical pain by a questionnaire of adjectives. Comparison of 2 epidural analgesia protocols].
A French version of the McGill pain questionnaire, the "Questionnaire Douleur Saint Antoine" (QDSA), was assessed prospectively by comparing two epidural analgesia protocols using bupivacaine. One hundred women in labour who asked for epidural analgesia were randomly allocated to two groups and received either 0.25% or 0.5% bupivacaine (mean initial doses 32.5 and 50 mg respectively) with adrenaline 1 in 200,000. All the patients were then instructed to trigger a patient controlled analgesia (PCA) device for top-up doses of 0.25% bupivacaine with adrenaline 1 in 400,000 once they became aware of pain returning. ⋯ On the other hand, the affective part of the score was only correlated with the level of anxiety and behaviour. The sensory part of this score was the only one to show a difference between the different initial doses given to the patients. The results obtained with this series of patients underline the value of a multidimensional assessment of labour pain.

Randomized Controlled Trial Clinical Trial[The effect of continuous thoracic peridural anesthesia on the pulmonary function of patients undergoing colon surgery. Results of a randomized study of 116 patients].
In a prospective randomized clinical investigation, we examined the influence of continuous thoracic epidural analgesia (TEA) on pulmonary function and pathologic chest X-ray findings. METHODS. One hundred sixteen patients having resection and/or anastomosis of the colon participated in this study; 57 were randomly assigned to the epidural group, whereas 59 were given systemic analgesia. ⋯ There was no difference in pO2 at any time. The number of pathologic chest X-ray findings showed no difference between both groups. Looking especially for infiltrates, dystelectasis, atelectasis, and congestion, we also could not demonstrate any difference between the groups. (ABSTRACT TRUNCATED AT 400 WORDS)

Randomized Controlled Trial Clinical Trial[The effect of 6% (40/0.5) hydroxyethyl starch and Ringer's lactate on blood coagulation, laboratory parameters and circulation during peridural anesthesia].
We investigated the effects of 6% hydroxyethyl starch (HES 40/0.5) and lactated Ringer solution (LRS) on blood coagulation tests and laboratory parameters during epidural anesthesia. Additionally, the efficacy of this prophylactic intravenous fluid supply in preventing sympathetic blockade induced hypotension was studied. METHODS. ⋯ The temporary increase in plasma volume after infusion of 6% HES 40/0.5 results in a greater hemodilution with a concomitant decrease of blood viscosity and improved microcirculation flow. These might be of interest in prevention of thromboembolic complications. The specific effects of the two solutions were also determinable during epidural blockade.
