Predictive factors of maternal hypothermia during Cesarean delivery: a prospective cohort study

AbstractPurposeAlthough perioperative hypothermia may increase maternal morbidity, active warming is infrequently performed to maintain normothermia during Cesarean delivery (CD). The aim of this prospective observational study was to determine the factors associated with maternal hypothermia in this setting.MethodsWomen scheduled for elective or emergency CD were consecutively included in this study from November 2014 to October 2015. Maternal temperature was measured using an infrared tympanic thermometer on the patient ’s arrival in the operating room, at skin incision, and at the end of skin suture. Maternal hypothermia was defined by tympanic temperature

Abstract IntroductionOur aim was to identify antepartum risk factors for neonatal hypoxic ischemic encephalopathy (HIE), with a focus on maternal body mass index and height. Material and methodsNational population‐based cohort study of 692 428 live‐born infants ≥ 36 gestational weeks in Sweden, 2009–2015. Data from the Swedish Medical Birth Register and the Swedish Neonatal Quality Register were linked. Short maternal stature was defined as ≤ 155 cm, and overweight as body mass index ≥ 25 kg/m2. Therapeutic hypothermia served as surrogate marker of moderate to severe HIE. Associations between maternal an...

Mice subjected to cold or caloric deprivation can reduce body temperature and metabolic rate and enter a state of torpor. Here we show that administration of pyruvate, an energy-rich metabolic intermediate, can induce torpor in mice with diet-induced or genetic obesity. This is associated with marked hypothermia, decreased activity, and...

AbstractBackgroundHypothermia is associated with an increased postoperative morbidity and mortality. Forced-air warming systems are the most effective methods for its prevention. When using a mattress, a reduction in the area of diffusion of warm air by crushing due to excess weight cannot be ruled out.MethodsWe designed a prospective study to compare the efficacy of a forced-air warming mattress (Bair Hugger ® 585) to prevent hypothermia (core temperature (CT°)

Publication date: 2 November 2017 Source:Cell, Volume 171, Issue 4 Author(s): Yi Chen, Xing Zeng, Xuan Huang, Sara Serag, Clifford J. Woolf, Bruce M. Spiegelman Adrenergic stimulation promotes lipid mobilization and oxidation in brown and beige adipocytes, where the harnessed energy is dissipated as heat in a process known as adaptive thermogenesis. The signaling cascades and energy-dissipating pathways that facilitate thermogenesis have been extensively described, yet little is known about the counterbalancing negative regulatory mechanisms. Here, we identify a two-pore-domain potassium channel, KCNK3, as a built-in...

In the background of obesity regulatory alterations in energy balance affecting peptide systems may also be assumed. Regulation of energy balance does not only involve maintenance of body weight but also that of metabolic rate and core temperature. Anabolic mediators with coordinated actions induce weight gain via increasing food intake with simultaneous hypometabolism and tendency for hypothermia, while catabolic mediators act in an opposite way. The contribution of alarin, a new member of the galanin peptide family, to the regulation of energy metabolism has been suggested.

Abstract Currently, more than 78.6 million adults in the United States are obese. A majority of the patient population receiving treatment for pain symptoms is derived from this subpopulation. Environmental factors, including the increased availability of food high in fat and sugar, contribute to the continued rise in the rates of obesity. The focus of this study was to investigate whether long-term exposure to a high-fat, energy-dense diet enhances baseline thermal and inflammatory nociception while reducing sensitivity to morphine-induced antinociception. Antinociceptive and hypothermic responses to morphine wer...
