benzodiazepines is a chemical class of drugs. muscle relaxant is not. all kinda specific drugs qualify as muscle relaxants, from many different classes of drugs, including things like some benzodiazepines, some anticholorgenics, some etc.valium is a muscel relaxant.ut since the OP specifically asked what is the most powerful muscle relaxant and not what works best for muscle relaxation, diazepam/clonazepam are both out of the question. The most powerful muscle relaxant from my experience is Carisoprodol (Soma).
If a vaginal ultrasound is done and no fetal pole or cardiac activity is seen, another ultrasound scan should be done in 3-7 days. Due to the fact that pregnancy dating can be wrong, it would be much too early at this point to make a clear diagnosis on the outcome of the pregnancy. Gestational Age Week 7 (Fetal Age: 5 weeks) Generally, from 6 Â½ -7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy.
Doctors use several different methods to listen to the fetal heartbeat. About 3 weeks, one day after fertilization, when the heart first begins to beat, the sound of the little heart is too soft to hear. Very soon thereafter, they can see the motion using ultrasound technology. A doctor's stethoscope is not sensitive enough to hear the embryo's heart beating.
