We have compared changes in haemodynamic variables before and during transurethral resection of the prostate in 22 patients under general or spinal anaesthesia. In the general anaesthetic group there was a significant decrease in cardiac output (mean 32% (SEM 5%)) and mean arterial pressure (14% (3%)) after induction of anaesthesia and a significant(More)
The Portex percutaneous trachestomy kit incorporates guidewire dilating forceps which pass over a guidewire and perform rapid dilatation. These forceps have curved jaws which are designed to reduce possible damage to the lateral and posterior walls of the trachea. The guidewire dilating forceps are first opened in front of the trachea to dilate the(More)
Intravenous infusions of enoximone or dobutamine were given, using a double dummy technique, in a randomized, double-blind study, to 18 patients with acute myocardial infarction who had persisting signs of left ventricular failure after treatment with intravenous diuretics. Blood pressure, heart rate and cardiac output, by transcutaneous Doppler(More)
We report a patient with homozygous sickle cell disease who underwent femoropopliteal bypass for claudication on walking 10m. Isotope studies showed a blood flow in his left femoral artery of only 0.808 ml. 100ml.min-1. The potential problems of sickle cell disease combined with peripheral vascular disease were probably reduced in this patient because he(More)
We have compared the haemodynamic effects of the imidazole derivative phosphodiesterase inhibitors enoximone and piroximone in patients with low cardiac output after cardiac surgery. Ten patients (group E) received enoximone and 10 patients (group P) received piroximone, both at a loading dose of 0.5 mg kg-1 followed by an infusion of 5 micrograms kg-1(More)
A retrospective casenote audit of the use of thrombolysis in 212 of 335 patients with acute myocardial infarction (63%) was carried out on the coronary care unit of a Sheffield teaching hospital. The overall inpatient mortality was 17%, 12% in the thrombolysis group and 26% in the remainder (p < 0.005). Patients aged 75 years or older were less likely to(More)
