“…To maintain normothermia, fluid warmers are designed to deliver fluid around body temperature (37°C), and their use has been recommended for all intra-operative infusions ≥ 500 ml in adults [1]. Administration of warmed intravenous fluids in conjunction with standard heat conservation measures has been shown to reduce the incidence of accidental peri-operative hypothermia significantly in gynaecological [8] and abdominal [9] surgery, as well as associated complications during orthopaedic lists [10]. In obstetric practice, the use of intra-operative warmed fluid is also associated with significantly higher Apgar scores in the newborn infant following caesarean section [11].…”

Peri‐operative warming devices: performance and clinical application

SummarySince the adverse consequences of accidental peri-operative hypothermia have been recognised, there has been a rapid expansion in the development of new warming equipment designed to prevent it. This is a review of peri-operative warming devices and a critique of the evidence assessing their performance. Forced-air warming is a common and extensively tested warming modality that outperforms passive insulation and water mattresses, and is at least as effective as resistive heating. More recently developed devices include circulating water garments, which have shown promising results due to their ability to cover large surface areas, and negative pressure devices aimed at improving subcutaneous perfusion for warming. We also discuss the challenge of fluid warming, looking particularly at how devices' performance varies according to flow rate. Our ultimate aim is to provide a guide through the bewildering array of devices on the market so that clinicians can make informed and accurate choices for their particular hospital environment.

“…The occurrence of shivering following anaesthesia was striking, which also could not be associated with the treatment scheme. Postoperative shivering is considered as a serious complication (Sarti et al 2005) and is regarded, on the one hand, as a thermoregulatory response (Greif et al 2003) and on the other hand, as a primarily pharmacological effect mainly of volatile anaesthetics even in patients with normothermia (Eberhart et al 2005, Hasankhani et al 2007). Isoflurane was The duration (min) of postanaesthetic shivering for every single dog is presented.…”

SummaryBeagle dogs continue to be used in experimental studies and preclinical and clinical trials, many of which address the usage of anaesthesia. In order to reduce the number of animals, researchers tend to conduct several experiments on a single animal. The question arises, however, as to whether or not this frequent usage involves more than simply additional stress and discomfort for the individual animal. Within the framework of an existing study involving six female Beagle dogs, we investigated the effects of repeated (5) isoflurane anaesthesia with xylazine/levomethadone/fenpipramide premedication carried out at short intervals (2 weeks) and compared these with the effects of two treatments intermitted by a longer resting period (8 weeks). To verify our hypothesis that frequent anaesthesia affects the dog's wellbeing more than the occasional anaesthesia, the following parameters were measured at regular intervals: body weight, body temperature, respiratory rate, blood pressure, reflexes and heart rate, both at rest and during a treadmill exercise. In addition, recovery behaviour subsequent to anaesthesia was monitored for one hour. Our observations indicate that the anaesthetic effects are most prominent 24 h after the anaesthetic treatment. However, crossover analysis of our data cannot show that there is no statistical difference of whether dogs were anaesthetized occasionally or frequently. In our study, it appears that frequent anaesthesia within a two-week period did not affect the wellbeing and general health of Beagle dogs in a super-additive manner and that a minimum of two-week testing-free period is sufficient to ensure complete recovery from the unwanted effects induced by anaesthesia.Keywords Repeated anaesthesia; isoflurane; premedication; Beagle dogs; animal welfare Beagle dogs continue to be used as laboratory animals in the development of new drugs or diagnostics, as well as for preclinical and clinical research. Complex questions and stressful or painful procedures often make it necessary to perform experiments under anaesthesia. In order to reduce the number of animals, researchers commonly conduct more than one experiment on the same animal. With regard to animal welfare, however, it needs to be ensured that the stress and discomfort for the single animal is not more than additive. To date, guidelines for anaesthesia in laboratory animals do not address the re-application of anaesthetics,
