Aim: To explore the suitability of existing formulas to estimate the body surface area (BSA) of newborns when direct measurement of surface estimation is not practical. Various calculations have been published to arrive at the BSA without direct measurement. Other factors are immature drug metabolism systems, and in newborn children, especially premature infants, the immaturity of the epidermal barrier. For infants with bw between 20-40 kg, the regression equation S=2.5.kg + 33; r=0.977 was found. Boyd E: The growth of the surface area of the human body. 4.

Estimation of human body surface area from height and weight. 2009 Jan;16(1):47-53. doi: 10.1016/j.arcped.2008.10.010. A suitable formula is therefore needed for body surface area (BSA) estimation for high-risk infants to more accurately devise therapeutic regimes in clinical practice. | Epub 2012 Jan 10. For infants below 20 kg, the relationship followed the regression equation S=3.6kg + 9; r=0.996. [8,9] also found a correlation between BSA and glomerular filtration rate, but this has been questioned by Dooley et al. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. In 589 term-newborns of normal weight and height, the five estimations (in cm2) were performed using four known BSA formulas by Boyd, Meban, Mosteller and Dubois, and the fifth arithmetic mean of these four formulas (BSA-Mean). Most of their mass is fat and water which weighs less. Body Composition and Surface Area The body composition of the fetus changes during gestation with a smaller proportion of body weight composed of water as gestation progresses. Mottling of the skin, a lacy pattern of small reddish and pale areas, is common because of the normal instability of the blood circulation at the skin's surface. The body surface was calculated from the DuBois and DuBois formula. Body Weight (kg) Surface Area (m2) 11 0.53 12 0.56 NIH Body surface area at birth and later risk for gestational diabetes mellitus among primiparous women. Epub 2008 Nov 25. Body surface area is used to help calculate the most accurate medication dosage for a patient. • Radiation: when the newborn is near cool objects, walls, tables, cabinets, without actually being in contact with them. USA.gov. The non-muscle cell mass and the muscle cell mass reach a 1:4 ratio in men whereas in women a 1:35 proportion--which is more favorable for pregnancy and lactation--is reached. | Conclusions: 1992]. These equations can easily be memorized and may be able to replace nomograms when bedside calculations of the S is required. 2009 Jan;16(1):47-53. doi: 10.1016/j.arcped.2008.10.010. Abushaban L, Mariappa TV, Rathinasamy J, Sharma PN. J Pediatr. Vaginal area. BSA = SQRT ((cm*kg)/3600) or in inches and pounds: BSA (m2) = SQRT ([Height (in) x Weight (lbs)]/ 3131) Weight is highly affected by the abnormalities in adipose tissue but however, body surface area BSA is usually known to be more effective because it does not depend upon the content or abnormality of adipose tissue in your body. Introduction. Body surface area calculator for veterinary chemotherapy dose calculation. | ANATOMIC STRUCTURE: ADULT: CHILD: Anterior head: 4.5%: 8.5%: Posterior head: 4.5%: 8.5%: Anterior torso: 18%: 18%: Posterior torso: 18%: 18%: Each Anterior Leg: 9% Various Body Surface Area formulas have been developed over the years, originally by Dr.s Du Bois & Du Bois, followed by Gehan and George, Haycock, Boyd and Mosteller. OBJ: Client Needs: Physiologic Integrity. Environ Geochem Health. BSA = About Us. 2017 Jul;82(1):36-46. doi: 10.1038/pr.2017.96. 2018 Apr;30(2):86-94. doi: 10.1016/j.jsha.2017.09.003. A suitable formula is therefore needed for body surface area (BSA) estimation for high-risk infants to more accurately devise therapeutic regimes in clinical practice. An infant's total body surface area 17 can be influenced by the disproportionate head size, especially in the more preterm infant. For similar reasons, acrocyanosis , or blueness of the skin of the hands and feet and the area surrounding the lips, is often present, especially if the infant is in a cool environment. The Mosteller formula 1 BSA (m2) = SQRT ([Height (cm) x Weight (kg) ]/ 3600) e.g. J Clin Anesth. Calculate. NLM Results The mean gestational age was 29.8 [± 2.38 standard deviation (SD)] weeks, ranging from 24 weeks to 35 weeks. The origin of the 1 x 73-m2 body surface area normalization: problems and implications. COVID-19 is an emerging, rapidly evolving situation. 5. The body surface area is used in many measurements in medicine, including the calculation of drug dosages and the amount of fluids to be administered IV The "normal" body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Methods: 2007 May;27(3):135-7. doi: 10.1111/j.1475-097X.2006.00718.x. Estimation of body surface area in various childhood ages--validation of the Mosteller formula. Body surface area in normal-weight, overweight, and obese adults. Weight. For infants below 20 kg, the relationship followed the regression equation S=3.6kg + 9; r=0.996. Normal reference ranges for the left ventricular mass and left ventricular mass index in preterm infants. A review of potential health implications of silver nanoparticles on human health.

Du Bois formula: The formula is depends on the product of the weight of individual raised to the power 0.425 and height raised to the power of 0.725 and 0.007184, i:e: Gehan EA, George SL: Estimation of human body surface area from height and weight. Other influential factors include the age and gender of the individual. To estimate your body surface area our BSA calculator uses the following formula : 0.20247 x height (m)0.725 x mass (kg)0.425 where height is in meters and mass is in kg. C. Optimal Body Surface Area. The newborn infant with a body temperature of between 36.0-36.4°C (96.8-97.5°F) may be under cold stress which gives rise to concern. • Individual investigators (protocols) should have clear recommendations for dosing in infants. The West nomogram, commonly used to calculate BSA, is a graph with several scales arranged so that when two values are known, the third can be plotted by drawing a line with a straight edge. You can calculate body surface area by Du Bois formula and Mosteller formula. Results: J Saudi Heart Assoc. Clipboard, Search History, and several other advanced features are temporarily unavailable. Gehan EA, George SL. For infants with bw between 20-40 kg, the regression equation S=2.5.kg + 33; r=0.977 was found. Would you like email updates of new search results?
