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...

INTRODUCTION: Transcatheter Aortic Valve Replacement (TAVR) procedures at our institution were complicated by perioperative hypothermia despite use of the standard of care forced-air convective warming device (the BairHugger, Augustine Medical Inc, Eden Prairie, MN, USA). To remedy this problem, we initiated a quality improvement process that investigated the use of a conductive warm water-circulating device (the Allon ThermoWrap, Menen Medical Corporation, Trevose, PA, USA), and hypothesized that it would decrease the incidence of perioperative hypothermia...

BACKGROUND: The successful treatment of military combat casualties with penetrating injuries is significantly dependent on the time needed to get the patient to an adequate treatment facility. Profound hypothermia-induced suspended animation for delayed resuscitation (SADR) is a novel approach for inducing cardiac arrest and buying additional time for such injuries. However, the time used to safely administer circulatory arrest (CA) is controversial. The goal of this study was to evaluate the safety of hypothermia-induced SADR over 90 and 120 min time intervals...

PURPOSE: Inadvertent perioperative hypothermia is a common problem for patients undergoing surgery. Heat redistribution from the body's core to the periphery after induction of anesthesia is the major contributor. DESIGN: A prospective randomized controlled trial was conducted to determine if reflective blankets are more effective than cotton blankets in reducing the core-peripheral temperature gradient and increasing peripheral compartment heat content during the preoperative phase among adult patients undergoing elective surgery of less than 1 hour...

BACKGROUND: Rates of hypothermia for women undergoing spinal anesthesia for cesarean delivery are high and prevention is desirable. This trial compared the effectiveness of preoperative warming versus usual care among women receiving intrathecal morphine, which is thought to exacerbate perioperative heat loss. METHODS: A prospective, single-blinded, randomized controlled trial compared 20 minutes of forced air warming (plus intravenous fluid warming) versus no active preoperative warming (plus intravenous fluid warming) in 50 healthy American Society of Anesthesiologists graded II women receiving intrathecal morphine as part of spinal anesthesia for elective cesarean delivery...

Inadvertent perioperative hypothermia is estimated to affect 70% of surgical patients and is associated with adverse clinical outcomes, lengthened hospital stays, and increased costs. To better understand the current level of nursing knowledge on this subject since the release of the "Guideline for prevention of unplanned patient hypothermia," we conducted an e-mail survey of AORN members. The overall response rate was 6.5% (N = 324), and most responding nurses overestimated or underestimated the lower and upper limits for normothermia...
