Filter by:Background: Postoperative hypothermia may result in relevant complications such as adverse cardiovascular events, wound infection, and coagulopathy with consecutive blood loss. Patients with open cardiac surgery using cardiopulmonary bypass are particular at risk for hypothermia. The study of Karalapillai and coworkers, analyzing a huge database incl. 43,158 patients with CPB, revealed 66% of them experiencing postoperative hypothermia during the first 24 hours and 0.3% longer than that. During cardiac surgery great parts of body surface including wound surface are exposed. Many of these patients receive large amounts of infusions and transfusions, and undergo hemodilution during CPB, which may additionally contribute to development of hypothermia. Objective of the planned study is to find out incidence and duration of postoperative hypothermia and also risk factors for hypothermia in cardiac patients. Further objective is the incidence of postoperative complications and its relation to postoperative core temperature. Methods: A retrospective chart review 780 patients who had been underwent cardiac surgery with CPB Included are patients ≥ 18 years old. Excluded are patients with preoperative hyperthermia (> 37.8 °C) and hypothermia (> 36 °C). The following parameters will be recorded: temperature is measured at ICU after arrived and after 6 hours which is primary outcome, biometric data include age, sex, body weight, height, ASA physical status, surgical procedure includes emergency cases, anesthetic and surgical (bypass-) times, infusion/transfusion-regimen, blood loss and urine output, coolest temperature during bypass, method of temperature protection, and the outcome of operation . All data will be described in number and percent and Pearson chi-square method will be used for analyze correlation between hypothermia and risk factor . P-value <0.05 will be defined to significant.
Shivering is one of the most commonly recognized problem associated with anesthesia, It is believed to be thermoregulatory in origin. Studies suggest that pre-warming the patient prior to the surgery can reduce the chances of hypothermia induced shivering during the post operative period. Forced air warmers are the most frequently used active warming devices in the peri-operative setting. Currently, our hospital does not pre-warm patients but if our study shows that pre-warming reduces post-operative shivering, we will be able to make an evidence based decision to start this practice.
Total joint patients have poor outcomes with infection since they are having permanent hardware implanted. Infection prevention in this group is therefore critical and a major source of discussion in both the orthopedic and anesthesia literature. Hypothermia has been shown to increase the risk of infection and blood loss. However, studies have not examined when in the operation or how fast patients temperatures drop. This study will observe how patients' temperatures change during total joint arthroplasty. By identifying when body temperature changes occur, prevention strategies may be developed and implemented.
Comparison of four methods for measuring temperature perioperatively in patients scheduled for laparoscopic surgery and intensive care patients who are hypo-, normo-and hyper terme; Bladder Monitoring, Nasopharyngeal, SpotOn TM, Zero heat flux method and Temporal Scanner. The study is a single-center, observational study carried out by the Central Surgical and Intensive Section at Vestfold Hospital Trust.
This is a randomized, open label, parallel two arm, clinical study, which compare the Bair Hugger forced-air warming blanket and the conventional warming care practice in China on patients undergoing major surgery to determine the impact of maintaining normothermia on intraoperative blood loss, requirement for transfusion of packed red blood cells and the changes of coagulation function.
Study Objective: - to project the incidence of perioperative hypothermia in patients with elective surgery under general anesthesia in China - to determine the risk factors associated with perioperative hypothermia. - to explore the patient outcome of hypothermia such as cardiovascular events, wound infection,hospital stay and so on. Study Design: The present study is a cross-sectional study with 30-day follow-up period.
The aim of the study is to evaluate a patient prewarming concept following the recommendations of the S3-guideline "Prevention of perioperative hypothermia" with respect to incidence and complications of perioperative hypothermia. The study hypothesis is that postoperative core temperature in adult patients after prewarming is significantly higher than in patients who were treated following actual standard protocol (passive insulation).
Studying the feasibility of an initial sedation with inhalated sevoflurane during therapeutic hypothermia of cardiac arrests resuscitated patients.
During anaesthesia for caesarean section it is common to lose heat and become hypothermic, (<36 degrees C). In order to try and avoid this all women are given warmed intravenous fluid and insulated from cold surfaces. There are also 2 types of machine available to actively warm women; 1. Forced Air Warming - that uses a disposable sheet the woman lies upon with lots of air pockets that have warm air blown into them continuously by a fan. 2. Conduction Warming Mattress - a thin mattress which covers the operating table and the woman lies on top. The padded mattress has strips of material that heat up when electricity passes through it, similar to a normal electric blanket. We plan to carry out a randomised controlled trial to compare these 2 methods with the current practice of no active warming. The hypothesis for this study is that active warming women during elective caesarean section prevents women's temperature from dropping and keeps them more comfortable than if active warming were not used.
The overall hypothesis is that better adherence to Kangaroo Mother Care (KMC) in combination with existing WHO thermoregulation care will reduce the incidence of moderate hypothermia (32-36 degrees C) or severe hypothermia (<32.0 degrees C) in term infants (greater than or equal to 37 weeks of gestational age) when compared with routine WHO thermoregulation alone.
