Ultrasonography is the primary tool for preoperative analysis of vein morphology for fistula creation in patients with end-stage renal disease. This study examines the effect of environmental temperature on the superficial vein size. Superficial veins of thirteen healthy volunteers were marked at three sites: cephalic vein in left lateral arm near cubital fossa, cephalic vein in left forearm at wrist, and basilic vein in left medial arm near cubital fossa. Mean diameters were recorded using ultrasound probe at 26°C and 43°C...

The aim of this randomized porcine study was to compare surface targeted temperature management (TTM) to endovascular TTM evaluated by cerebral diffusion-weighted magnetic resonance imaging (MRI): apparent diffusion coefficient (ADC), and by intracerebral/intramuscular microdialysis. It is well known that alteration in the temperature affects ADC, but the relationship between cerebral ADC values and the cooling method per se has not been established. Eighteen anesthetized 60-kg female swine were hemodynamically and intracerebrally monitored and subsequently subjected to a baseline MRI...

Clobazam, a 1,5-benzodiazepine FDA-approved in 2011, is commonly used to treat anxiety and epilepsy. It has not associated with hypothermia until very recently, in a case report involving two pediatric patients. Here, we report the first case of hypothermia development in an adult patient with epilepsy associated with clobazam use. A couple months after starting clobazam, the patient started developing episodes of hypothermia every several weeks, with temperatures ranging from 90 °F-95 °F. Normothermia was achieved with Bair Hugger therapy...

PURPOSE: To report a case of hypothermia in a patient with intellectual disability treated with thioridazine. SUMMARY: A 59-year-old female presented to the emergency department with altered mental status, generalized weakness, chills, and fatigue and was diagnosed with a urinary tract infection. Upon completion of a history and physical examination, the patient was found to be hypothermic with a temperature of 91 F. A Bair Hugger protocol was initiated to manage hypothermia, and a taper schedule for thioridazine was initiated as it was identified as a possible culprit for the patient's hypothermia...

BACKGROUND: Perioperative hypothermia is a common problem, challenging the anesthesiologist and influencing patient outcome. Efficient and safe perioperative active warming is therefore paramount; yet, it can be particularly challenging in pediatric patients. Forced-air warming technology is the most widespread patient-warming option, with most forced-air warming systems consisting of a forced-air blower connected to a compressible, double layer plastic and/or a paper blanket with air holes on the patient side...

A quality improvement project intended to promote maintenance of normothermia through active prewarming was carried out at a pediatric specialty hospital. An alternative active, forced-air warming product (Bair Paws warming gowns) was trialed in place of the existing active warming product (Bair Hugger blankets). Converting to the new product was intended to improve patient and staff compliance with prewarming recommendations. The alternative forced air active warming product was favored by both staff and patients, and the rate of compliance with this practice nearly doubled following the change in product...

This pilot study determined the rate of bacterial contamination on surgical drapes of small animal patients warmed intra-operatively with the Bair Hugger(®) forced air warming system compared to a control method. Surgical drapes of 100 patients undergoing clean surgical procedures were swabbed with aerobic culturettes at the beginning and end of surgery. Samples were cultured on Trypticase soy agar. Contamination of the surgical drapes was identified in 6/98 cases (6.1%). There was no significant difference in the number of contaminated surgical drapes between the Bair Hugger(®) and control groups (P = 0...

Forced-air warming devices are effective for the prevention of surgical hypothermia. However, these devices intake nonsterile floor-level air, and it is unknown whether they have adequate filtration measures to prevent the internal buildup or emission of microbial contaminants. We rated the intake filtration efficiency of a popular current-generation forced-air warming device (Bair Hugger model 750, Arizant Healthcare) using a monodisperse sodium chloride aerosol in the laboratory. We further sampled 23 forced-air warming devices (same model) in daily hospital use for internal microbial buildup and airborne-contamination emissions via swabbing and particle counting...

Forced-air warming exhaust may disrupt operating theatre airflows via formation of convection currents, which depends upon differences in exhaust and operating room air temperatures. We investigated whether the floor-to-ceiling temperatures around a draped manikin in a laminar-flow theatre differed when using three types of warming devices: a forced-air warming blanket (Bair Hugger™); an over-body conductive blanket (Hot Dog™); and an under-body resistive mattress (Inditherm™). With forced-air warming, mean (SD) temperatures were significantly elevated over the surgical site vs those measured with the conductive blanket (+2...

BACKGROUND: Hypothermia in burns is common and increases morbidity and mortality. Several methods are available to reach and maintain normal core body temperature, but have not yet been evaluated in critical care for burned patients. Our unit's ordinary technique for controlling body temperature (Bair Hugger®+ radiator ceiling + bed warmer + Hotline®) has many drawbacks e.g.; slow and the working environment is hampered.The aim of this study was to compare our ordinary heating technique with newly-developed methods: the Allon™2001 Thermowrap (a temperature regulating water-mattress), and Warmcloud (a temperature regulating air-mattress)...

Resistive heating is an alternative to forced-air warming which is currently the most commonly used intra-operative warming system. We therefore tested the hypothesis that rewarming rates are similar with Hot Dog(®) (Augustine Biomedical) resistive and Bair Hugger(®) (Arizant) forced-air heating systems. We evaluated 28 patients having major maxillary tumour surgery. During the establishment of invasive monitoring, patients became hypothermic, dropping their core temperature to about 35 °C. They were then randomly assigned to rewarming with lower-body resistive (n = 14) or forced-air (n = 14) heating, with each system set to 'high'...

BACKGROUND AND OBJECTIVE: Unintentional hypothermia of a patient is a common adverse effect during surgical procedures. Many strategies can be used to reduce heat loss. The aim of this prospective, randomised, controlled study was to determine whether the use of the thermal suit (T-Balance) could prevent surgical patients from experiencing thermal loss better than conventional measures. METHODS: We examined a group of consecutive patients undergoing transurethral resection of the prostate under spinal anaesthesia...

BACKGROUND: Forced-air warming (FAW) is widely used to prevent hypothermia during surgical procedures. The airflow from these blowers is often vented near the operative site and should be free of contaminants to minimize the risk of surgical site infection. Popular FAW blowers contain a 0.2-μm rated intake filter to reduce these risks. However, there is little evidence that the efficiency of the intake filter is adequate to prevent airborne contamination emissions or protect the internal air path from microbial contamination buildup...

BACKGROUND: The purpose of this study was to develop an in vitro torso model constructed with fluid bags and to determine whether this model could be used to differentiate between the heat prevention performance of devices with active chemical or radiant forced-air heating systems compared with passive heat loss prevention devices. METHODS: We tested three active (Hypothermia Prevention Management Kit [HPMK], Ready-Heat, and Bair Hugger) and five passive (wool, space blankets, Blizzard blankets, human remains pouch, and Hot Pocket) hypothermia prevention products...

BACKGROUND: Several adverse consequences are caused by mild perioperative hypothermia. Maintaining normothermia with patient warming systems, today mostly with forced air (FA), has thus become a standard procedure during anesthesia. Recently, a polymer-based resistive patient warming system was developed. We compared the efficacy of a widely distributed FA system with the resistive-polymer (RP) system in a prospective, randomized clinical study. METHODS: Eighty patients scheduled for orthopedic surgery were randomized to either FA warming (Bair Hugger warming blanket #522 and blower #750, Arizant, Eden Prairie, MN) or RP warming (Hot Dog Multi-Position Blanket and Hot Dog controller, Augustine Biomedical, Eden Prairie, MN)...

PURPOSE: Intraoperative and postoperative hypothermia occur commonly; mild hypothermia (34-36 degrees C) is associated with adverse events. The use of perioperative warming devices has become routine, but currently available active warming devices may be limited in certain circumstances. The vitalHEAT Temperature Management System provides conductive warming (circulating warm water) around a single extremity together with a vacuum that is applied to the limb. In this randomized trial, we tested the hypothesis that the vitalHEAT system is non-inferior to the Bair Hugger during unilateral total knee arthroplasty...

Various reliable body heat-regulating systems have been designed and developed with the aim of maintaining an adequate body temperature in the course of major surgery. This is crucial to avoid the onset of potentially severe complications that are especially serious in elderly and debilitated subjects. Among these systems, the Bair Hugger blanket has demonstrated excellent efficacy. However, some reports in the literature have suggested that the use of such devices can increase the risk of nosocomial infections, particularly surgical wound infections...

BACKGROUND: We previously described a convection warming technique (Cassey J, Armstrong P, Smith GE, Farrell PT. Paediatr Anaesth 2006; 16: 654-62). This study further analyses the children in that original study with three aims: (i) to investigate factors purported to influence children's heating rates, (ii) to describe the most effective usage of this warming technique, and (iii) to understand better the physiology of convection warming. METHODS: Children having anaesthesia for elective surgery lasting longer than 90 min in ambient temperature 21 degrees C were warmed by a 'Bair Hugger' attached to a custom-built heat dissipation unit...
