Does epinephrine infiltration in septoplasty make any difference? A double blind randomised controlled trial.

Infiltration of lignocaine with epinephrine is used with cocaine in septoplasty, in attempt to improve haemostasis and thereby improve the surgical field. This practice is widespread despite the lack of evidence to support its efficacy in the literature. Thirty patients undergoing septoplasty were randomised into two groups -- one in whom infiltration was performed with lignocaine (2%) with adrenaline (1:80,000) and a control group who received lignocaine (2%).

Airway management training using the laryngeal mask airway: a comparison of two different training programmes.

Nurses without prior experience in the use of the laryngeal mask airway (LMA) were randomly allocated to one of two groups to be trained in the emergency technique of insertion of an LMA. Group A (32 nurses) were trained only on a manikin and group B (20 nurses) were trained on a manikin and with live anaesthetised patient practice in theatre (five successful insertions). Without further practice, both groups were asked to insert an LMA in a live patient in theatre 3 months after initial training.

Growth hormone responses to treadmill sprinting in sprint- and endurance-trained athletes.

The purpose of the present study was to examine the growth hormone (GH) response to treadmill sprinting in male (M) and female (F) sprint- and endurance-trained athletes. A group of 11 sprint-trained (ST; 6M, 5F) and 12 endurance-trained (ET; 6M, 6F) athletes performed a maximal 30-s sprint on a nonmotorized treadmill. Peak power and mean power expressed in watts or in watts per kilogram body mass were higher in ST than in ET (P < 0.

Dynamics of phenol degradation by Pseudomonas putida.

Pure cultures of Pseudomonas putida (ATCC 17484) were grown in continuous culture on phenol at dilution rates of 0.074-0.085 h(-1) and subjected to step increases in phenol feed concentration.

Intrasplenic blood cell kinetics in man before and after brief maximal exercise.

1. After a 4 min period of maximal exercise in 10 normal subjects (14 studies), there was a consistent decrease in total blood volume and a consistent increase in erythrocyte indices, which were maximal immediately after exercise. Peripheral platelet and leucocyte counts increased, but did not reach maximal values until 5-10 min after the end of exercise.
