A thorough family history should be taken at sis after 16 weeks gestation by removing a small amount this time to determine if other people in the family are of the amniotic fluid surrounding the baby and analyzing affected.

Although called a “heelstick generic 100mg kamagra soft with visa,” any highly vascularized capillary bed can be used (fin- ger cheap kamagra soft 100mg with mastercard, ear lobe, or great toe). Auto- mated safety lancets (eg, BD Genie lancet for fingersticks and the BD Quick Heel Lancer for heelsticks) are also available. Most labs can usually make laboratory determinations on small samples from the pedi- atric age group. For a capillary blood gas, the blood is usually transferred to a 1-mL heparinized syringe and placed on ice. Position the patient in the dorsal lithotomy position (knees flexed and abducted), and per- form an aseptic perineal prep with sterile vaginal lubricant or povidone–iodine spray. Remove the spiral electrode from the sterile package and place the guide tube firmly against the fetal presenting part. Advance the drive tube and electrode until the electrode contacts the presenting part. Maintaining pressure on the guide tube and drive tube, rotate the drive tube clockwise until mild resistance is met (usually one turn). Press together the arms on the drive tube grip, which releases the locking device. Care- fully slide the drive and guide tubes off the electrode wires while holding the locking device open. Attach the spiral electrode wires to the color-coded leg plate, which is then connected to the electronic fetal monitor. Complications • Fetal or maternal hemorrhage, fetal infection (usually scalp abscess at the site of in- sertion) Interpretation Normal FHR is 120–160 bpm. Accelerations are increases in the FHR, and although they can be associated with fetal distress (usually in association with late decelerations), they are almost always a sign of fetal well-being. Decelerations are transient falls in FHR related to a uterine contraction and are of three types: 1. Early Decelerations: Seen in normal labor, slowing of the FHR clearly associated with the onset of the contraction and the FHR promptly returns to normal after the contraction is over. Late Deceleration: Slowing of the FHR that occurs after the uterine contraction starts and the rate does not return to normal until well after the contraction is over. This type of 13 pattern is often associated with uteroplacental insufficiency (fetal acidosis or hypoxia).
