Perioperative hypothermia is common in high-risk surgical patients. Anaesthesia impairs central thermoregulation, allowing re-distribution of body heat. Cool ambient temperatures and high-volume fluid administration accelerate loss of heat to the environment. Randomized, controlled trials have proven that mild hypothermia increases the incidence of wound infection and prolongs hospitalization, ...

Haemodynamic depression is commonly defined as a change in arterial pressure (hypotension with systolic pressure values of less than 90 mmHg) and heart rate (bradycardia, heart rate of less than 60 beats per minute). Carotid angioplasty and stenting (CAS) can result in many complications, particularly in the perioperative period. Apart from the most serious complications, such as stroke and tem...

Total body water (TBW) is consistently 70% of the lean body weight across age and sex ranges but varies as a percentage of actual bodyweight between groups and individuals owing to varied deposition of adipose tissue, which contains less water than muscle. TBW is 75% of total body weight in neonates, 70% in infants and 45% in the elderly. The average adult male (70 kg) has 60% of total body wei...

The importance of timely administration of antibiotics for prophylaxis of surgical site infections has led to pressure on anesthesiologists to administer antibiotics. We present a survey of members of the American Association of Clinical Directors designed to evaluate the role of the anesthesiologist in the selection and administration of perioperative antibiotics. A 13-question survey was sent...

BACKGROUND Previously, the authors found "liberal" fluid administration (approximately 3 l Ringer's lactate [RL]) to improve early rehabilitation after laparoscopic cholecystectomy, suggesting functional hypovolemia to be present in patients receiving "restrictive" fluid administration (approximately 1 l RL). Because volume kinetic analysis after a volume load may distinguish between hypovolemi...

Accurate assessments of intravascular fluid status are an essential part of perioperative care and necessary in the management of the hemodynamically unstable patient. Goal-directed fluid management can facilitate resuscitation of the hypovolemic patient, reduce the risk of fluid overload, reduce the risk of the injudicious use of vasopressors and inotropes, and improve clinical outcomes. In th...

according to limitations in blood product resources and to prevent unnecessary transfusions and afterwards complications in perioperative period of total hip arthroplasty, authors administered fibrinogen concentrate in a pilot randomized clinical trial to evaluate bleeding and need to blood transfusion in preoperative period. thirty patients (3-75 years old) with asa physical status class i or ...

To address debates over recommended perioperative fluid management, Nisanevich et al. designed a randomized prospective study to compare liberal versus restricted fluid administration during intraabdominal surgery. The team enrolled 152 patients scheduled to undergo intraabdominal surgery, and randomly assigned half of them (n 75) to receive liberal amounts of lactated Ringer’s solution (bolus ...
