    Abstract:
    Eight patients undergoing transurethral resection of the prostate (TURP) using sterile distilled water as an irrigating fluid were studied. The concentrations of plasma haemoglobin, serum sodium, serum prostatic acid phosphatase protein (PAP) and plasma osmolality were determined as possible indicators of absorption of irrigating fluid. In 3 patients there was a marked increase in plasma haemoglobin immediately postoperatively with a maximum of 3.3 g haemoglobin/l plasma. In the remaining 5 patients the plasma haemoglobin level did not exceed 0.7 g/l immediately postoperatively. In all cases there was a fairly rapid return of the elevated plasma haemoglobin level to preoperative values. There was also a postoperative increase in the serum PAP level which was not correlated with the simultaneous increase in plasma haemoglobin concentration. There was no significant change in the sodium, potassium or albumin concentration in serum nor in plasma osmolality postoperatively. There was some decrease in the postoperative serum creatinine and uric acid levels. The preoperative serum creatinine concentration was within reference limits in 7 patients and borderline high in 1 patient. The haemoglobin binding plasma protein haptoglobin showed a slight non-significant increase immediately postoperatively and a significant decrease in concentration 2 hours postoperatively. The mean plasma haemoglobin concentration immediately postoperatively did not exceed the mean preoperative haemoglobin binding capacity of serum. The mean preoperative haemoglobin binding capacity was 1.2 g/l and the mean plasma haemoglobin level was 1.2 g/l immediately postoperatively. Two hours later the mean plasma haemoglobin level was 0.8 g/l. The mean serum haptoglobin concentration was 2.4 g/l preoperatively, 2.6 g/l immediately postoperatively and 2.0 g/l 2 hours later.(ABSTRACT TRUNCATED AT 250 WORDS)
