Filter by:On-pump CABG surgery deleteriously affects hematological and coagulation profiles of patients and this effect was accentuated by the use of cold bypass. PO altered platelet may count and function and prolonged clotting times correlates with amount of daily PO blood wound drainage and number of blood products units used, but prolonged aPTT is the best predictor for these events.
Nowadays, caesarean sections account for about 7% of all surgical procedures worldwide. Over 30% of the patients undergoing a caesarean section experience a fall of the body core temperature under 36°C during the procedure. Following a retrospective cohort design, this study aims to examine the magnitude of hypothermia in the parturient and newborn population as well as the impact and efficiency of forced-air warming on preventing it. The researchers plan to conduct a retrospective analysis of the caesarean section treatment protocol at our institution over a period of 5 months including approximately 300 patients who underwent both elective and emergency caesarean sections.
In an avalanche burial with an air pocket hypercapnia (and hypoxia) develops within few minutes, hypercapnia increases the rate of cooling and therefore the development of hypothermia. The Triple H Syndrome (Hypoxia, Hypercapnia, Hypothermia) occurs. This specific combination of the three parameters is unique for avalanche burial with an air pocket. Every single parameter has a substantial effect on the hemoglobin-oxygen dissociation curve, but until now no study described the combination of these three parameters. This curve will be measured under these specific conditions in a specifically developed in vitro model, to quantify its shifts and to show if there are combined effects of pCO2 and temperature. The newly developed method will be validated in comparison with an established method. The project will be performed with whole blood, drawn by healthy volunteers, in an experimental setting. The samples will be blinded to the investigator and analyzed in a randomized manner.
This study evaluates the effect of active prewarming on the frequency and duration of perioperative hypothermia. 50% of patients will receive active warming with forced-air devices prior to entering the operating room, and the other 50% will not receive any active heating measures.
Previous research has shown beneficial effects of prewarming on preventing inadvertent perioperative hypothermia (IPH). Warming the surface of the body before the induction of anesthesia can reduce the temperature difference between the core and periphery, thereby reducing the degree of core-to-peripheral thermal redistribution. It has been proved that initiation of warming before surgery can be more useful for preventing IPH than warming only during surgery. Nevertheless, there are not many researches on effects of short period (<30 min) prewarming, especially in gynecologic laparoscopic surgery. Accordingly, the investigators designed this study to test if IPH can be effectively prevented when 10 minutes of prewarming is added to intraoperative active warming in patients undergoing gynecologic laparoscopic surgery.
The present study aims at testing if the TherMax blood warmer is more accurate and reliable in reaching and maintaining chosen target temperature during continuous renal replacement therapy as compared to the Prismaflo IIS blood warmer used for the PrismaFlex system.
Study of adult patients with severe all-cause trauma having a body temperature less than 36°Celsius (C) that is managed by a Mobile Emergency Service team and oriented towards a Vital Emergency Room. Currently two devices are used to warm patients during their care at the scene of an accident: a survival blanket and heating in the emergency vehicle. Despite these two devices many patients arrive in hypothermia (body temperature less than 36°C) in emergency departments. The objective of this study is to evaluate the effectiveness of a body warmer associated with standard warming devices on the correction of hypothermia compared to the standard procedure in severely traumatized patients with hypothermia . It is a national multicentric study with 14 participating Mobile Emergency Service centers and hopefully will include 612 patients. The study will be carried out according to a pattern of 28 successive periods of one week each during the winter period (October to April), for a total duration of 7 months. 14 action periods ON (warming standard procedure + body warmer) and 14 control periods OFF (warming standard procedure) will be run in random order for each center.
The study TAULÍ-PREVINQ-WARM will assess the rate of perioperative hypothermia in patients submitted to major surgical procedures at the operating room main area (and at the ambulatory surgery building for ophthalmologic major procedures) of the Parc Taulí, Hospital Universitari, Sabadell, Barcelona.
Given the scarce donor supply, an increasing number of so-called marginal or extended criteria donor (ECD) organs have been used for liver transplantation. These ECD liver grafts are, however, known to be associated with a higher rate of early allograft dysfunction (EAD) and primary non-function because of a greater vulnerability to ischemia-reperfusion injury. The end-ischemic Hypothermic Oxygenated Machine Perfusion (HOPE) technique may improve outcomes of liver transplantation with ECD grafts by decreasing reperfusion injury. The study aim is to assess the efficacy of HOPE used before transplantation of ECD liver grafts from brain-dead donors in reducing postoperative EAD within the first 7 postoperative days (POD) compared to simple cold static storage. The study is comparative open-label, multicenter, national, prospective, randomized, in two parallel groups, using the gold standard procedure as control.
Controlling hypothermia is essential in anesthesia to limit postoperative complications. Temperature monitoring is therefore essential. However, the reliability of esophageal temperature during open chest lung surgery is discussed and not accurately assessed in the literature.
