Summary:The role of heater cooler units (HCUs) in the transmission of Mycobacterium chimaera during open heart surgery has been recognised since 2013. Subsequent investigations uncovered a remarkable global outbreak reflecting the wide distribution of implicated devices. HCUs are an essential component of cardiopulmonary bypass operations and their withdrawal would severely affect capacity for life-saving cardiac surgery. However, studies have demonstrated that many HCUs are contaminated with a wide range of microorganisms, including M. chimaera and complex biofilms. Whole genome sequencing of M. chimaera isolates recovered from one manufacturer's HCUs, worldwide, has demonstrated a high level of genetic similarity, for which the most plausible hypothesis is a point source contamination of the devices. Dissemination of bioaerosols through breaches in the HCU water tanks is the most likely route of transmission and airborne bacteria have been shown to have reached the surgical field even with the use of ultraclean theatre ventilation. Controlling the microbiological quality of the water circulating in HCUs and reducing biofilm formation has been a major challenge for many hospitals. However, enhanced decontamination strategies have been recommended by manufacturers and while not always effective in eradicating M. chimaera from HCUs, UK hospitals have not reported any new cases of M. chimaera infection, since implementing these mitigation strategies. Water safety groups in hospitals should be aware that water in medical devices such as HCUs can act as a vector in the transmission of potentially fatal water-borne infections.

“…In this study, the group that received only a circulating-water mattress to maintain intraoperative temperature was more than twice as likely to experience shivering during the recovery period as the group that received both a mattress and a forced-air warming blanket (Group W = 43.6%, Group F = 20.7%, respectively). It has been demonstrated that regulating body temperature using a forced-air warming device in combination with a circulating-water mattress is more effective in preventing shivering than the use of a mattress alone, as in the findings of Kim et al [ 11 ]. In Group F, the average intraoperative temperature and the temperature at the end of surgery were significantly higher than those of Group W. From these significant differences in temperature, we may infer that the temperature during surgery has had an effect on the occurrence of postanesthetic shivering.…”

BackgroundDuring head and neck surgery including orthognathic surgery, mild intraoperative hypothermia occurs frequently. Hypothermia is associated with postanesthetic shivering, which may increase the risk of other postoperative complications. To improve intraoperative thermoregulation, devices such as forced-air warming blankets can be applied. This study aimed to evaluate the effect of supplemental forced-air warming blankets in preventing postanesthetic shivering.MethodsThis retrospective study included 113 patients who underwent orthognathic surgery between March and September 2015. According to the active warming method utilized during surgery, patients were divided into two groups: Group W (n = 55), circulating-water mattress; and Group F (n = 58), circulating-water mattress and forced-air warming blanket. Surgical notes and anesthesia and recovery room records were evaluated.ResultsInitial axillary temperatures did not significantly differ between groups (Group W = 35.9 ± 0.7℃, Group F = 35.8 ± 0.6℃). However, at the end of surgery, the temperatures in Group W were significantly lower than those in Group F (35.2 ± 0.5℃ and 36.2 ± 0.5℃, respectively, P = 0.04). The average body temperatures in Groups W and F were, respectively, 35.9 ± 0.5℃ and 36.2 ± 0.5℃ (P = 0.0001). In Group W, 24 patients (43.6%) experienced postanesthetic shivering, while in Group F, only 12 (20.7%) patients required treatment for postanesthetic shivering (P = 0.009, odds ratio = 0.333, 95% confidence interval: 0.147–0.772).ConclusionsAdditional use of forced-air warming blankets in orthognathic surgery was superior in maintaining normothermia and reduced the incidence of postanesthetic shivering.

“…It could also cause heavy financial burden to patients due to prolonged hospital stay (Galvão et al., 2009). Thus, there has been an increasing interest in the prevention of UIH by means of intraoperative active warming strategies, such as forced‐air warming (FAW) system (Shaw, Steelman, DeBerg, & Schweizer, 2017), prewarming technology before anaesthesia (Poveda, Clark, & Galvão, 2013) and circulating warming mattresses (Kim et al., 2014). The FAW device, which is comprised of a disposable plastic blanket, joining hose and main machine generating warmed air, has been widely applied in the operating room to surgical patients to prevent UIH for 20 years (Shaw et al., 2017).…”

Background: Unintentional intraoperative hypothermia was regarded as a common intraoperative symptom with serious complications. The active warming strategies of forced-air warming (FAW) and carbon-fibre polymer-fabric resistive heating were considered to be effective interventions for preventing hypothermia. However, the effectiveness of them was not reported consistently. Aim: To evaluate the effectiveness of carbon-fibre polymer-fabric resistive heating compared with FAW in preventing hypothermia in patients undergoing elective surgeries. Design: Systematic review and meta-analysis. Methods: A rigorous systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis reporting checklist. Searching strategy was undertaken on the electronic databases of Cumulative Index to Nursing and Allied Health Literature, MEDLINE, PubMed, EMBASE and Medical Literature Retrieval Service. The assessment of study quality was performed through risk of bias of Cochrane handbook of systematic review of interventions. Data synthesis was conducted through meta-analysis with sensitive analysis. The quality of evidence was graded using Grading of Recommendations Assessment, Development and Evaluation approach. Results: A total of five randomised controlled trials with 282 patients undergoing elective surgeries were included in the quantitative synthesis. Four studies concluded that FAW was as effective as carbon-fibre polymer-fabric resistive heating in preventing hypothermia. However, one study yielded a different conclusion that the efficacy of FAW was superior to carbon-fibre polymer-fabric resistive heating with small incidence of hypothermia. Meta-analysis found that FAW was more effective than carbon-fibre polymer-fabric resistive heating in preventing hypothermia. Conclusions: In the elective abdominal surgery, carbon-fibre polymer-fabric resistive heating was less effective than FAW on the prevention of hypothermia. However,
