Aim: This study was conducted to understand the research hotspots, research trends and research frontiers for hypothermia in surgical patients and provide a reference for developing effective measures to reduce the incidence of hypothermia in these patients. Design: Using CiteSpace software, a visual analysis of 1288 included articles related to hypothermia in surgical patients was performed. Methods: CiteSpace software is a Java application that supports knowledge research, data visualization and analysis of literature databases. The following data were retrieved: title, abstract, year, keywords, author, academic institution, journal and citations. The included literature was analysed using CiteSpace visualization software, knowledge mapping, collaborative network analysis, cluster analysis and highlighting keywords for visualization. Results: A total of 1288 articles related to hypothermia in surgical patients were included, with the largest number of articles published in the United States (448), followed by in Germany (104) and China (102). The top three institutions, journals and authors were from the United States. The most common keywords were perioperative 'hypothermia', 'risk factors' and 'anesthesia'. [ABSTRACT FROM AUTHOR]

Aim: Most Finnish births take place in hospital, but out-of-hospital deliveries (OHDs) have increased. This study evaluated trends and reasons for OHDs in the Tampere University Hospital catchment area.Methods: The study cohort included all planned and unplanned OHDs in the Hospital area from 1996 to 2011; the control group comprised two hospital births for each OHD. Trends in incidence and risk factors for OHDs, including neonatal morbidities, were established and compared to the controls.Results: OHDs accounted for 67 (0.10%) of the 76 773 births in the area, the proportion remaining unchanged between 1996 and 2005, but then increasing. Risk factors associated with OHDs were smoking during pregnancy, short labour, higher number of previous births, single status, residence more than 35 kilometres from the delivery unit and fewer prenatal visits. OHD cases were more likely to be admitted to the neonatal care unit than controls and to be treated for suspected infections and hypothermia.Conclusion: Smoking, short duration of labour, a higher number of previous births, single status and longer distances from the delivery unit were associated with OHDs. Eight (12%) mothers had OHDs without antenatal care, and their infants had more neonatal morbidities. [ABSTRACT FROM AUTHOR]

Aim To determine the occurrence and risk factors of sudden unexpected postnatal collapse ( SUPC) in presumably healthy newborn infants. Methods All live-born infants during a 30-month period, in five major delivery wards in Stockholm, were screened, and possible cases of SUPC thoroughly investigated. Infants were ≥35 weeks of gestation, had an Apgar score >8 at 10 min and collapsed within 24 h after birth. Maternal, infant, event characteristics and outcome data were collected. Results Twenty-six cases of SUPC were found among 68 364 live-born infants, an incidence of 38/100 000 live births. Sixteen of these cases of SUPC required resuscitation with ventilation >1 min, and 14 of these remained unexplained (21/100 000). Fifteen of the 26 children were found in a prone position, during skin-to-skin contact, 18 were primipara, and 13 occurred during unsupervised breastfeeding at <2 h of age. Three cases occurred during smart cellular phone use by the mother. Five developed hypoxic-ischaemic encephalopathy ( HIE) grade 2, and 4 underwent hypothermia treatment. Twenty-five infants had a favourable neurological outcome. Conclusion SUPC in apparent healthy babies is associated with initial, unsupervised breastfeeding, prone position, primiparity and distractions. Guidelines outlining the appropriate monitoring of newborns and safe early skin-to-skin contact should be implemented. [ABSTRACT FROM AUTHOR]

Bleeding is a considerable clinical problem during and after pediatric heart surgery. While the primary cause of bleeding is surgical trauma, its treatment is often complicated by the presence of coagulopathy. The principle causes of coagulopathy are discussed to provide a context for treatment. The role of laboratory and point of care tests, which aim to identify the cause of bleeding in the individual patient, is also discussed. An attempt is made to examine the current evidence for available therapies, including use of blood products and, more recently proposed, approaches based on human or recombinant factor concentrates.

We proposed that many Intensive Care Unit (ICU) patients would be hypothermic in the early postoperative period and that hypothermia would be associated with increased mortality. We retrospectively reviewed patients admitted to ICU after surgery. We recorded the lowest temperature in the first 24 h after surgery using tympanic membrane thermometers. We defined hypothermia as < 36 °C, and severe hypothermia as < 35 °C. We studied 5050 consecutive patients: 35% were hypothermic and 6% were severely hypothermic. In-hospital mortality was 5.6% for normothermic patients, 8.9% for all hypothermic patients (p < 0.001), and 14.7% for severely hypothermic patients (p < 0.001). Hypothermia was associated with in-hospital mortality: OR 1.83 for each degree Celsius (°C) decrease (95% CI: 1.2–2.60, p < 0.001). Given the evidence for improved outcome associated with active patient warming during surgery we suggest conducting prospective studies of active warming of patients admitted to ICU after surgery.

Background: Induced mild hypothermia is an emerging therapy that has been shown to reduce the combined outcome of death or severe neurodevelopmental disabilities in asphyxiated full-term infants if started within 6 h after birth. Aim: To study the feasibility and safety of inducing hypothermia in asphyxiated infants already at the referring hospital by stopping active warming. Methods: Temperatures during passive induction of hypothermia were prospectively collected from transported asphyxiated infants. Results: Between December 2006 and April 2008, 37 infants of the total birth cohort of 40 350 fulfilled the criteria for hypothermia treatment. Eighteen of 34 infants treated with induced hypothermia were outborn. The rectal temperatures of the infants were 33.0–36.4°C before transport and 31.0–36.5°C on arrival. Six of the infants had a sub-therapeutic (<33.0°C) rectal temperature on arrival. Conclusion: Passive induction of hypothermia by turning off active warming devices is possible, making an earlier start of hypothermia achievable. However, there is a substantial risk of unintended excessive cooling; therefore, continuous monitoring of the central temperature is mandatory when such a strategy is used. [ABSTRACT FROM AUTHOR]

Background and Objectives Plateletpheresis is the most frequent type of apheresis, with demand for these products continuously increasing. Hypothermia is a common side-effect of apheresis, which may have an effect on the donor's body functions. The aim of this study was to examine the effects of warming methods on plateletpheresis donors’ temperature, cardiac function and cytokines. Materials and Methods Fifty plateletpheresis donors were randomly assigned to a control group ( n = 25) or a warming group ( n = 25), with air and blood warmers during plateletpheresis. The effects of the treatment were examined by comparing body temperature, heart rate, blood pressure, Holter EKG pattern, serum interleukin-1β (IL-1β), interleukin-2 (IL-2), tumour necrosis factor-α (TNF-α) concentration, the white blood count, the white blood fraction, and the platelet count at a point in time between the two groups. Results In the control group, the tympanic temperature decreased more during apheresis compared to the warming group ( P = 0·014). The decrease of diastolic blood pressure was significantly greater in the control group compared to the warming group ( P = 0·010). As for cardiac function, the frequency of abnormal beats was generally higher in the control group, but the difference was not significant. IL-2 and TNF-α decreased significantly after plateletpheresis in the control group only, while there was no change in the warming group. Conclusion The decrease of temperature during plateletpheresis resulted in changes in haemodynamics and cytokines. The warming methods used in this study can prevent the decrease of temperature in donors, and may be helpful in maintaining the haemodynamic and cytokine balance. [ABSTRACT FROM AUTHOR]
