I know this is a really stupid question, but I'm going to ask it anyway. Do all brands of Lactated Ringers have the exact same ingredients? Probably grasping at straws here, but it seems to me that Zachary didn't start having bowel problems until I started this new bag of Ringers. The vet was out of Baxter brand (the brand I just finished using), so we went with Hospira instead. I've used Hospira without any problem before, but with Zach's system being so delicate right now, it seems like any small thing can cause issues.
Here are the ingredients on the Hospira:
Sodium chloride 600mg; sodium lactate ANHYD, 310mg; potassium chloride 30mg; calcium chloride dihydrate 20mg in water for injection. May contain HCI or NaOH for pH adjustment.
Sodiium 130 mEq; potassium 4 mEq; calcium 3 mEq; chloride 109 mEq; lactate 28 mEq.
273 m0smol/liter (calc); pH 6.6 (6.0 to 7.5).
