Hi everyone I am a nurse in pacu at a large hospital I have 7 yrs ICU experience had a patient post femoral endarectomy with history of 3 mi's and 8 stents. Also history of vtach and bradycardia post surgery he became hypotensive so I started neo gave albumin and hespan with improvement in bp. Ebl was 550 so we drew hgb and it had dropped 4 grams. So of course we would transfuse when blood ready. Anesthesia md wanted a gram of calcium chloride iv and since I had only given in code situations I wanted to make sure it was safe..called pharmacy. Verified with me 3 times (he was not happy I questioned his order) i asked him to explain the reason and mechanism behind this met in this specific situation. I do not give anything without knowing why. He said to increase bp and contractility. Everything I looked up points to it causing hypotension when giving I've and helps contractility only in code situations non responsive to epi. Calcium level was 9.7 already and if I understand right it causes k to lower when given increasing arrhythmia risks. The explanation didn't make me happy or help me understand so just wondering if anyone else has ever given for the reasons stated by md? I just want to understand!!!
