“…In the present study, the degree of hypothermia was severe in the geriatric group, but no shivering was observed. These results support the previous findings that geriatric patients become more hypothermic during surgery [10,15] and shiver less during both spinal anesthesia [16] and after general anesthesia [17] than do younger patients.…”

Postoperative hypothermia in geriatric patients undergoing arthroscopic shoulder surgery

Hypothermia, which is defined as a core temperature below 36°C, occurs in patients undergoing arthroscopic shoulder surgery as a result of heat loss due to the administration of large amounts of room temperature irrigation fluid [1-4]. Perioperative hypothermia causes problems such as morbid cardiac events [5], coagulopathy and increased transfusion requirements [6], surgical wound infections [7], and pro-longed postoperative recovery [8]. Geriatric patients have a higher risk of intraoperative and postoperative hypothermia because they are less able to control their body temperature [9,10]. As the human lifespan continues to increase, the number of geriatric patients who undergo shoulder arthroscopy for rotator cuff and acromial pathology resulting from age-wear phenomena is also increasing. However, there are no reports on decreases of body temperature in geriatric patients undergoing arthroscopic

“…Compensatory thermoregulatory responses are decreased in the aged (Hajat et al, 2007), mostly due to altered regulation of skin blood flow in the setting of a reduced microcirculation (Holowatz et al, 2010). For the same reason, rewarming of the older adult takes longer than the time required to rewarm young adults (Carli et al, 1986). During surgery and anesthesia, the initial decrease in core temperature results from the redistribution of heat to the peripheral microcirculation.…”

Aging is associated with a progressive loss of function in all organs. Under normal conditions the physiologic compensation for age-related deficits is sufficient, but during times of stress the limitations of this reserve become evident. Explanations for this reduction in reserve include the changes in the microcirculation that occur during the normal aging process. The microcirculation is defined as the blood flow through arterioles, capillaries and venules, which are the smallest vessels in the vasculature and are embedded within organs and tissues. Optimal strategies to maintain the microvasculature following surgery and other stressors must use multifactorial approaches. Using skin as the model organ, we will review the anatomical and functional changes in the microcirculation with aging, and some of the available clinical strategies to potentially mitigate the effect of these changes on important clinical outcomes.

Health effects of heating, ventilation and air conditioning on hospital patients: a scoping review

et al. 2020

View full text Add to dashboard Cite

Background: In the face of climate change, the protection of vulnerable patients from extreme climatic conditions is of growing interest to the healthcare sector and governments. Inpatients are especially susceptible to heat due to acute illness and/or chronic diseases. Their condition can be aggravated by adverse environmental factors. Installing air conditioning can be seen as an element of public health adaptation because it was shown to improve mortality rates of hospital patients experiencing hot temperatures. Still, the mediating factors and resulting health effects are largely unknown. Method: The PRISMA-ScR guideline was followed for this scoping review. Available evidence on the health effects of Heating, Ventilation, Air Conditioning (HVAC) and fans was searched in Medline, Embase and the Cochrane Library. The focus of the search strategy was on inpatients of the hospital. Grey literature was screened on 14 relevant websites. English and German publications were eligible without restrictions on publication date. Results were charted according to the categories population, intervention, control and outcome together with a qualitative description. Results: The review process yielded eleven publications of which seven were issued after 2003. Seven were clinical trials, three cross-sectional studies and one was a case report. The publications described the installation of HVAC on general wards and in intensive care units. Main topics were heat stress protection and support of thermoregulation, but also the rewarming of hypothermic patients. HVAC use resulted in a recovery effect shown by improved vital signs, reduced cardiac stress, accelerated recuperation and greater physical activity. This protective effect was demonstrated by a shorter hospital stay for patients with respiratory disease and a reduction of mortality for heat illness patients. Conclusion: This scoping review summarises the fragmented evidence on health effects of HVAC and fan utilisation for inpatients. Installing HVAC has the potential to improve patients' outcomes and to make hospital treatment more efficient during heat waves. The application of HVAC could be a promising adaptation measure to mitigate the adverse effects of climate change on health and healthcare systems.
