Please talk about this with your physician. None of us are qualified to answer your question. Last year, a pregnant woman asked my Chemistry teacher if it was OK for her to do labs. He rightly told her that no way was he going to make that judgment call. He told her to show her doctor the list of chemicals we'd be using. Frankly, there were items on that list that I would definitely not want to be around if I were pregnant.
As for microbiology, you'll constantly be working with bacteria. Yes, it's fairly weak, lab-grown bacteria. And yes, we are surrounded by bacteria every moment. But do you want to take the chance? Again, only you, with your doctor's input, can answer these questions. I hope I don't come off as a sourpuss. Really, I think science courses rock! But no one's assurances here should convince you one way or the other.
Sign In Register Now! But I did want to know if any of you have taken the class and how the experience was for you? Thank you!!! Original poster's comments 2. See all replies 1. KimbapLove said:. I wasn't pregnant when I took it, but I can't remember being expose….
Thank you!! BabyK said:. With my first I was taking anatomy and physiology during pregnancy …. The only thing is the smell is pretty bad Everything was fine and he is now a healthy 8 year old. But I agree with the previous poster, some of the smells are rough. I always tried to stay close to an open window or the door so I could go out of the lab for a breath of fresh air if I needed too. I am an anatomy professor and lab manager at a medical school so I was working with cadavers for many more hours than students normally do for the entirety of this pregnancy.
I was also teaching with embalmed non-human specimens with my last pregnancy. Plus, one of my anatomy students this fall semester was in her third trimester when she took the class.
The diastolic pressure tends to fall more than systolic pressure, the maximum decline around mid gestation. As early as 13 weeks, the gravid uterus can compress the inferior vena cava when the woman is lying supine. Venous blood is diverted via collaterals, particularly the vertebral venous plexus to drain via the azygous system.
Obstruction of the aorta occurs to a lesser degree but can result in decreased placental blood flow. This is of great importance when positioning a patient on the operating table.
During regional anaesthesia, the effects of aorto-caval compression will be exaggerated due to a lack of compensatory reflexes subsequent to the sympathetic blockade.
This can lead to profound hypotension. In extreme hypotension or fetal compromise such as a bradycardia the patient can be turned to the full left lateral position. Red cell volume also increases due to increased erythropoietin production, but not enough to prevent a dilutional anaemia occuring. The blood viscosity is therefore also reduced which may slightly decrease cardiac work. The platelet count tends to remain normal although there is probably an increase in their turnover.
There is a steady rise in white cell count peaking during labour. The total concentration of plasma protein is reduced due to the increase in plasma volume. This results in a drop in the colloid oncotic pressure, and may account for the oedema seen in pregnancy. Therefore, suxamethonium may have a slightly prolonged duration of action.
The pharmacokinetics of protein bound drugs will be affected. Coagulation is affected in pregnancy with an increase in most of the coagulation factors but also an increase in fibrinolytic activity. The result is a somewhat hyper-coagulable state. Thrombo-embolic disease is a very common condition and is one of the most important causes of maternal mortality in developed countries. The renal system undergoes marked changes in function during pregnancy due to hormonal effects, the increased metabolic load of the fetus and also due to outflow obstruction of the ureters by the enlarging uterus.
As a result, the clearance of urea, uric acid and creatinine all increase and their plasma concentrations are lower in pregnancy. In pregnancy there is a relaxation of the lower oesophageal sphincter and an increase in intra-gastric pressure due to the expanding uterus. There is also an increased risk of gastric regurgitation and aspiration during induction of general anaesthesia in the later stages of pregnancy.
Pregnancy itself does not prolong gastric emptying time but labour pain and any opioids administered for the pain will do so. Due to the combination of factors above, a rapid sequence induction is considered mandatory when inducing general anaesthesia in the third trimester and for 48 hours after delivery.
The placenta produces relaxin, a hormone that causes widespread relaxation of ligaments. This results in widening and increased mobility of the pubis and sacro-iliac joints to allow passage of the fetus through the birth canal.
Pain relating to these joints may occur during the later stages of pregnancy.
