Postoperative parameters.

Parameters	Tourniquet n = 24	Vasopressin n = 24	p-value
Post Op. Haemoglobin (gm/dl):
Range	8.1-10.4	8.4 -10.6	0.001
Mean	8.9±0.53	9.5±0.53
Reduction in Haemoglobin (g/dl)	1.60±0.35	0.99±0.18
p-value	<0.001†	<0.001†
Post Op. Haematocrit (%):
Range	24.5 – 31	23-32	<0.001
Mean	26.5±1.56	28.7±1.70
Reduction in Haematocrit (%)	5.34±1.13	2.95±0.61
p-value	<0.001 †	<0.001 †
Blood transfusion requirement:
No transfusion	19 (79.17%)	22 (91.67%)	0.416 ‡
One unit whole blood transfusion	5 (20.83%)	2 (8.33%)

* Value adjusted for one unit whole blood transfusion = 0.8 g/dl rise in haemoglobin and 2.5% rise in haematocrit.

^† p-value calculated by Student’s paired t test.
