For patients in extremis from respiratory failure or shock, securing vascular access is crucial, along with establishing an airway and ensuring adequacy of breathing and ventilation. Peripheral intravenous catheter insertion is often difficult, if not impossible, in infants and young children with circulatory collapse. Intraosseous (IO) needle placement, shown in the images below, provides a route for administering fluid, blood, and medication. An IO line is as efficient as an intravenous route and can be inserted quickly, even in the most poorly perfused patients.

Five percent of pregnant women have gestational diabetes, so if you're expecting, understanding the basics of this common condition is vital

A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor with or without use of drugs or techniques to induce labor, and delivers her baby in the normal manner, without forceps, vacuum extraction, or a cesarean section. Assisted vaginal delivery (AVD) occurs when a pregnant woman goes into labor with or without the use of drugs or techniques to induce labor, and requires the use of special instruments such as forceps or a vacuum extractor to deliver her baby vaginally.

- A baby born with two heads is expected to survive after doctors removed the parasitic twin that was “feeding off” her blood supply. The baby girl, who is yet to be named, was born via C-section at Ram Snehi Hospital in northern India last month

Neurogenic shock is a distributive type of shock resulting in low blood pressure, occasionally with a slowed heart rate, that is attributed to the disruption of the autonomic pathways within the spinal cord. It can occur after damage to the central nervous system such as spinal cord injury.

If you're pregnant, you're likely paying extra close attention to your body. If you happen to feel a cramp you may worry that it is a sign of a miscarriage. While the first trimester is the most common time for miscarriages, there are other reasons for cramps. Whether it signals a miscarriage depends on when it occurs, the severity of the cramping, and whether you're experiencing other symptoms alongside it.

This baby was born with an adult sized tongue - and she just completed a surgery that will change her life.

The pain is frequently severe and is described as throbbing or pulsating. Nausea is common, and many migraine patients have a watering eye, a running nose, or congestion. If these symptoms are prominent, they may lead to a misdiagnosis of sinus headaches.

The examination room should be quiet, warm and well lit. After you have finished interviewing the patient, provide them with a gown (a.k.a. "Johnny") and leave the room (or draw a separating curtain) while they change. Instruct them to remove all of their clothing (except for briefs) and put on the gown so that the opening is in the rear. Occasionally, patient's will end up using them as ponchos, capes or in other creative ways. While this may make for a more attractive ensemble it will also, unfortunately, interfere with your ability to perform an examination! Prior to measuring vital signs, the patient should have had the opportunity to sit for approximately five minutes so that the values are not affected by the exertion required to walk to the exam room. All measurements are made while the patient is seated. Observation: Before diving in, take a minute or so to look at the patient in their entirety, making your observations, if possible, from an out-of-the way perch. Does the patient seem anxious, in pain, upset? What about their dress and hygiene? Remember, the exam begins as soon as you lay eyes on the patient. Temperature: This is generally obtained using an oral thermometer that provides a digital reading when the sensor is placed under the patient's tongue. As most exam rooms do not have thermometers, it is not necessary to repeat this measurement unless, of course, the recorded value seems discordant with the patient's clinical condition (e.g. they feel hot but reportedly have no fever or vice versa). Depending on the bias of a particular institution, temperature is measured in either Celcius or Farenheit, with a fever defined as greater than 38-38.5 C or 101-101.5 F. Rectal temperatures, which most closely reflect internal or core values, are approximately 1 degree F higher than those obtained orally. Respiratory Rate: Respirations are recorded as breaths per minute. They should be counted for at least 30 seconds as the total number of breaths in a 15 second period is rather small and any miscounting can result in rather large errors when multiplied by 4. Try to do this as surreptitiously as possible so that the patient does not consciously alter their rate of breathing. This can be done by observing the rise and fall of the patient's hospital gown while you appear to be taking their pulse. Normal is between 12 and 20. In general, this measurement offers no relevant information for the routine examination. However, particularly in the setting of cardio-pulmonary illness, it can be a very reliable marker of disease activity. Pulse: This can be measured at any place where there is a large artery (e.g. carotid, femoral, or simply by listening over the heart), though for the sake of convenience it is generally done by palpating the radial impulse. You may find it helpful to feel both radial arteries simultaneously, doubling the sensory input and helping to insure the accuracy of your measurements. Place the tips of your index and middle fingers just proximal to the patients wrist on the thumb side, orienting them so that they are both over the length of the vessel.

The cardiovascular system is a closed system if the heart and blood vessels. The heart pumps blood through a closed system of blood vessels. Blood vessels allow blood to circulate to all parts of the body. Arteries usually colored red because oxygen rich, carry blood away from the heart to capillaries within the tissues. Veins usually colored blue because oxygen poor, carry blood to the heart from the capillaries.

The Hypertensive urgency must be distinguished from hypertensive emergency. Urgency is defined as severely elevated blood pressure (ie, systolic >220 mm Hg or diastolic >120 mm Hg) with no evidence of target organ damage.
