In the delivery room, wrapping a low-birth-weight neonate (defined as ≤2.499 g) in a polyethylene bag reduces the risk of hypothermia. However, extended use of the bag (e.g., during neonatal surgery) might conceivably increase the risk of thermal stress and thus body overheating. Here, we assessed the efficacy of a polyethylene bag in infants assigned to wrap (W) or nonwrap (NW, control) groups during placement of a percutaneous vena cava catheter by applying a new mathematical model that calculates heat exchanges for covered and uncovered body segments...

BACKGROUND: Inadvertent perioperative hypothermia (IPH) leads to surgical complications and increases length of stay. IPH rates are high with the current standard of care, forced air warming (FAW). Our hypothesis is that a prototype thermal compression device that heats the popliteal fossa and soles of the feet, with lower leg compression, increases perioperative temperatures and reduces IPH compared to the current standard of care. METHODS: Thirty six female breast surgery patients, at a tertiary academic hospital, were randomized to the device or intraoperative FAW (stage I) with a further 18 patients randomized to the device with a single heating area only (stage II, popliteal fossa or sole of the feet)...

BACKGROUND: Perioperative hypothermia may affect maternal and neonatal outcomes after obstetric spinal anesthesia. Core temperature is often poorly monitored during spinal anesthesia, due to the lack of an accurate noninvasive core temperature monitor. The aim of this study was to describe core temperature changes and temperature recovery during spinal anesthesia for elective cesarean delivery. We expected that obstetric spinal anesthesia would be associated with a clinically relevant thermoregulatory insult (core temperature decrease >1...

INTRODUCTION: Pulmonary endarterectomy (PEA) is the most effective treatment available for chronic thromboembolic pulmonary hypertension (CTEPH). Patient selection, surgical technique and perioperative management have improved patient outcomes, which are traditionally linked to surgical and center experience. However, optimal perfusion care has not been well defined. The goal of the international survey was to better characterize the contemporary perfusion management of PEA and highlight similarities and controversies...

Inadvertent perioperative hypothermia (body core temperature < 36 °C) is a serious complication leading to increased rates of wound infection, higher blood loss associated with increased transfusion requirements as well as patient dissatisfaction among others. Body core temperature is a vital parameter and needs constant monitoring just like heart rate, blood pressure and arterial oxygen saturation. Patient-, anesthesia-, surgery- and environment-related risk factors were identified for occurring perioperative hypothermia...

Amino acid (AA) infusion is sometimes selected to avoid hypothermia during general anesthesia. However, the widespread clinical use of AA infusion therapy has not been established. This study aimed to clarify the evidence that AA infusion can increase patient body temperature and improve clinical outcomes using the Grading of Recommendations Assessment, Development, and Evaluation system. We searched MEDLINE (PubMed), Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi (Japana Centra Revuo Medicina) in November 2015...

BACKGROUND: Unintentional perioperative hypothermia causes serious adverse effects to surgical patients. Thermal suit (T-Balance(®) ) is an option for passive warming perioperatively. We hypothesized that the thermal suit will not maintain normothermia more efficiently than conventional cotton clothes when also other preventive procedures against unintentional hypothermia are used. METHODS: One hundred patients were recruited to this prospective, randomized trial...

BACKGROUND: Neonatal aortic arch reconstruction, typically performed with deep hypothermia and selective cerebral perfusion, leaves splanchnic organ protection dependent on hypothermia alone. A simplified method of direct in-field descending aortic perfusion during neonatal arch reconstruction permits the avoidance of deep hypothermia. We hypothesize that direct splanchnic perfusion at mild hypothermia provides improved or equivalent safety compared with deep hypothermia and may contribute to postoperative extracardiac organ recovery...

Cardiac surgery on a patient with cold agglutinin disease is high risk for thromboembolism due to hypothermia perioperative. A 75-year-old woman with cold agglutinin disease underwent aortic valve replacement for severe aortic stenosis. Cold antibody was detected by preoperative screening test for blood transfusion. In order to prevent thromboembolic event during the operation, we maintained rectal temperature at around 36 degrees centigrade during the cardiopulmonary bypass by warming blood in the bypass circuit...

BACKGROUND: Perioperative hypothermia decreases nutrient and oxygen delivery to tissues and, in adult studies, increases the risk of infectious complications (ICs). Gastroschisis (GS) places newborns at risk for hypothermia by nature of exposed viscera and excessive heat loss. Although hypothermia is a known cause of mortality in GS, the rate of ICs in this at-risk cohort has not yet been delineated. MATERIALS AND METHODS: A retrospective cohort study was performed at our single tertiary-referral hospital, evaluating patient and operative characteristics of all GS infants who underwent operative closure...

BACKGROUND: Techniques for aortic surgery continue to evolve. A real-world snapshot of patients undergoing elective surgery for aneurysm in the modern era is helpful to assist in deciding the appropriate timing for intervention. We herein describe our experience with 100 consecutive patients who underwent primary elective surgery for aneurysm of the proximal thoracic aorta over a two-year period at a single institution. METHODS: The majority of our patients were male, mean age 61...

INTRODUCTION: Peritoneal insufflation with warm-humidified (WH) CO2 gas during minimally invasive surgical procedures is purported to prevent hypothermia and peritoneal desiccation and is associated with decreased postoperative IL-6 levels. This randomized study's purpose was to determine the clinical impact of WH versus cold-dry (CD) CO2 in minimally invasive colon resection (MICR), and to assess perioperative plasma levels of IL-6, TIMP-1, sVEGF-R1, and HSP-70 after MICR. METHODS: Operative and short-term clinical data plus perioperative blood samples were collected on MICR patients randomized to receive either WH (36...

PURPOSE: Although 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. METHODS: Women 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...

BACKGROUND: Perioperative hypothermia may increase the incidences of wound infection, blood loss, transfusion, and cardiac morbidity. U.S. national quality programs for perioperative normothermia specify the presence of at least 1 "body temperature" ≥35.5°C during the interval from 30 minutes before to 15 minutes after the anesthesia end time. Using data from 4 academic hospitals, we evaluated timing and measurement considerations relevant to the current requirements to guide hospitals wishing to report perioperative temperature measures using electronic data sources...

BACKGROUND: Surgical site infections (SSIs) are a common source of postoperative morbidity and a marker of surgical quality. The ability to predict the incidence of SSIs is limited and most models have poor predictive value. We sought to identify risk factors associated with SSIs and develop a prediction model for SSIs after major abdominal surgery. METHODS: A total of 1744 patients undergoing pancreatic, hepatobiliary, and colorectal resections between January 1, 2010 and August 31, 2013 at Johns Hopkins Hospital were identified...

BACKGROUND & PROBLEMS: Hypothermia is the cause of multiple problems such as delayed awaking from anesthesia, feelings of discomfort, increased oxygen consumption, and increased risks of surgical wound infection and complications. A review of the record of post-operative patients receiving general anesthesia (GA) revealed that only 74% of the patients in our post-anesthesia room (PAR) had restored their body temperature to 36℃ after 60 minutes. Through situation analysis, several causes were identified, including insufficient warming facilities, lack of standard procedures and an audit system, lack of knowledge regarding hyperthermia among nurses, and the incompleteness of perioperative warming interventions performed by the healthcare team...

INTRODUCTION: Inadvertent perioperative hypothermia occurs frequently during elective caesarean section but perioperative active body warming is not widely used. There is a paucity of evidence of its use in the obstetric population, and no applicable guidelines. We set out to identify a superior active warming method for preventing inadvertent perioperative hypothermia. METHODS: Following ethical approval, 132 women presenting for uncomplicated elective caesarean section with spinal anaesthesia were recruited...
