Fig. 2From: Effect of 0.9% NaCl compared to plasma-lyte on biomarkers of kidney injury, sodium excretion and tubular transport proteins in patients undergoing primary uncemented hip replacement – a randomized trialEffect of Isotonic saline vs. PlasmaLyte on arterial blood gas levels of chloride (a) and pH (b) in a double-blinded, placebo-controlled study of 38 patients. Blood samples were drawn before anesthesia (baseline), right after surgery (after surgery) and in the morning of the postoperative day (postoperative day). Values are shown as means ± SD. Statistics are performed with unparried t-test to test difference in response between treatments, † = p < 0.05. Paired t-test was used to test statistical significant difference from baseline, * = p < 0.05Back to article page
