    • The effect of hypoxaemia on fetal cardiac function 

      Bhide, Amarnath (Doctoral thesis; Doktorgradsavhandling, 2017-08-01)
      Objectives The objectives were 1. To study the effect of placental embolisation as well as maternal hypoxaemia on fetal left and right ventricular function as reflected by pulsed-wave Doppler-derived myocardial performance index (MPI). 2. To study myocardial systolic and diastolic function of the fetal left and right ventricles using ultrasound speckle tracking technique to measure global strain ...

    • Effects of nifedipine and sildenafil on placental hemodynamics and gas exchange during fetal hypoxemia in a chronic sheep model 

      Alanne, Leena; Bhide, Amarnath; Hoffren, Jonna; Lantto, Juulia; Huhta, Heikki; Kokki, Merja; Haapsamo, Mervi; Acharya, Ganesh; Rasanen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-16)
      Introduction - We hypothesized that nifedipine and sildenafil would have no detrimental effects on placental hemodynamics and gas exchange under fetal hypoxemia.<p> <p>Methods - In 33 chronically instrumented fetal sheep, placental volume blood flow (QPlac) and umbilical artery (UA) vascular impedance were measured by Doppler ultrasonography. Fetal carotid artery blood pressure and blood gas ...

      Bhide, Amarnath; Acharya, Ganesh; Baschat, Ahmet Alexander; Bilardo, Caterina Maddalena; Brezinka, Christoph; Cafici, Daniel; Ebbing, Cathrine; Hernandez-Andrade, Edgar A.; Kalache, Karim; Kingdom, John; Kiserud, Torvid; Surendran, Sailesh Kumar; Lee, Wesley; Lees, Christoph; Leung, Kwok Yin; Malinger, Gustavo; Mari, Giancarlo; Prefumo, Federico; Sepulveda, Waldo; Trudinger, Brian (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-19)
      The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is a scientific organization that encourages sound clinical practice, teaching and research related to diagnostic imaging in women's healthcare. The ISUOG Clinical Standards Committee (CSC) has a remit to develop Practice Guidelines and Consensus Statements as educational recommendations that provide healthcare practitioners ...

    • Peripheral chemoreflex activation and cardiac function during hypoxemia in near-term fetal sheep without placental compromise 

      Lantto, Juulia; Erkinaro, Tiina; Haapsamo, Mervi; Huhta, Heikki; Alanne, Leena; Kokki, Merja; Ohtonen, Pasi; Bhide, Amarnath; Acharya, Ganesh; Rasanen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-09)
      A drop in arterial oxygen content activates fetal chemoreflex including an increase in sympathetic activity leading to peripheral vasoconstriction and redistribution of blood flow to protect the brain, myocardium, and adrenal glands. By using a chronically instrumented fetal sheep model with intact placental circulation at near-term gestation, we investigated the relationship between peripheral ...
