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. The aim of this study was to assess the risk of contamination of the surgical site correlated to the use of the Bair Hugger blanket during hip replacement surgery. To this end, the level of bacterial contamination of the air in the operating theatre was quantified with and without the use of the Bair Hugger, during the course of 30 total non-cemented hip implants performed in patients with osteoarthritis. Sampling was done both in the empty theatre and during surgical procedures, in different zones around the operating table and on the patient's body surface. Statistical analysis of the results demonstrated that the Bair Hugger system does not pose a real risk for nosocomial infections, whereas it does offer the advantage of preventing the potentially very severe consequences of hypothermia during major orthopaedic surgery. In addition, monitoring patients over the six months following the operation allowed us to exclude a later manifestation of a nosocomial infection.
为了在大手术过程中维持适当的体温，人们设计并开发了各种可靠的身体体温调节系统。这对于避免在老年和体弱患者中尤其严重的潜在严重并发症的发生至关重要。在这些系统中，Bair Hugger保暖毯已显示出卓越的功效。然而，文献中的一些报告表明，使用此类设备会增加医院感染的风险，尤其是手术伤口感染的风险。本研究的目的是评估在髋关节置换手术期间，与使用Bair Hugger保暖毯相关的手术部位污染风险。为此，在30例为骨关节炎患者实施的全非骨水泥型髋关节置换手术过程中，分别在使用和不使用Bair Hugger保暖毯的情况下，对手术室空气中的细菌污染水平进行了量化。在空手术室以及手术过程中，在手术台周围的不同区域以及患者体表进行了采样。结果的统计分析表明，Bair Hugger系统不会对医院感染构成真正风险，而它确实具有防止在大型骨科手术期间体温过低可能产生的非常严重后果的优势。此外，在术后六个月对患者进行监测使我们能够排除医院感染的后期表现。
