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.
While it may be possible to detect a pregnancy as early as 5 1/2 weeks. Because the tiny sac containing the baby and its heart is so tiny, an ultrasound may not be able to detect pregnancy at this stage.If the baby can be seen at 6 to 7 weeks, their heart beat may even be detected.Between 7 and 8 weeks, the baby and their heart beat can both be detected relatively easily.After the 8th week of pregnancy the heart beat and the baby can be clearly seen.n ultrasound may be repeated a week or so after this point to check the babyâs progress and growth. A newer type of ultrasound known as a Transvaginal ultrasound is a technique used mainly to visualize the womanâs reproductive organs. This type of ultrasound has a better chance of detecting an early pregnancy.
