Well we are almost 3 hours into when Ian was taken back into the OR. There is a nurse liaison who comes out every hour to give us an update...the first update was just to let us know they had gotten a few of his lines in they needed for the surgery. About 15 minutes later the general surgeon came out to let us know the central line had been placed and looked good. This line can stay in as long as possible while he is inpatient. For the 2nd update from the RN liaison, she said that she thought they had the arterial line in before but she was wrong and they were working on getting that in when she was in the OR checking in. The a-line is extremely important as it is used to monitor the blood pressure real time and to obtain samples for aterial blood gas measurements. Since we know Ian will need to get blood, having this line to monitor his blood pressures is beyond important. The 3rd update just happened and as the nurse was leaving the OR, Dr. M was scrubbed and heading in. All of these things were factored into the 6-8 hour time frame. There is a chance we will get a bonus hour but will have to see how things go.
