ReviewPoint-of-care monitoring for the management of trauma-induced bleeding.
Knowledge of trauma-induced coagulopathy has been grown in the past and point-of-care suitable devices for coagulation testing have been introduced. Methodology and clinical application of different systems for point-of-care coagulation monitoring are shown with a focus on thrombelastography as measured by TEG, rotational thromboelastometry as measured by ROTEM and impedance aggregometry as measured by the multiplate analyser and ROTEM platelet. ⋯ Point-of-care assessment of coagulation in trauma patients appears to be at least promising. However, because published data mostly are of retrospective or observational nature only, there is a need for prospective, randomized and controlled studies.

ReviewHaemotherapy algorithm for the management of trauma-induced coagulopathy: an Australian perspective.
Recent advances in the understanding of the pathophysiological processes associated with traumatic haemorrhage and trauma-induced coagulopathy have resulted in improved outcomes for seriously injured trauma patients. However, a significant number of trauma patients still die from haemorrhage. This article reviews the various transfusion strategies utilized in the management of traumatic haemorrhage and describes the major haemorrhage protocol (MHP) strategy employed by an Australian trauma centre. ⋯ There are advantages and disadvantages to each of the various MHP strategies and the evidence base to support one above another with any certainty is lacking at this time. One strategy cannot be considered superior to the other and the choice of MHP is dependent on interpretation of the current literature and local institutional logistical considerations. A number of exciting studies are currently underway that will certainly increase the evidence base and help inform clinical practice.

Impairment and/or disability resulting from any of a number of etiologies will afflict a significant number of anesthesiologists at some point during their career. The impaired anesthesiologist can be difficult to identify and challenging to manage. Questions will arise as to if, how, and when colleagues, family members, or friends should intercede if significant impairment is suspected.This review will examine the common sources of impairment among anesthesiologists and the professional implications of these conditions. We will discuss the obligations of an anesthesiologist and his/her colleagues when there is sufficient suspicion that he/she might be impaired. ⋯ Some degree of impairment will occur to one-third of anesthesiologists during the course of their career. It is important to understand how such impairments might impact the safe practice of anesthesiology.

ReviewSpectrum of postoperative complications in pulmonary hypertension and obesity hypoventilation syndrome.
The purpose of this review is to identify chronic pulmonary conditions which may often not be recognized preoperatively especially before elective noncardiac surgery and which carry the highest risk of perioperative morbidity and mortality. ⋯ Pulmonary hypertension is a well recognized risk factor for postoperative complications after cardiac surgery but the literature surrounding noncardiac surgery is sparse. Pulmonary hypertension was only recently classified as an independent risk factor for postoperative complications in the American Heart Association/American College of Cardiology Foundation Practice Guideline for noncardiac surgery. Spinal anesthesia should be avoided in most surgeries on patients with pulmonary hypertension because of it's rapid sympatholytic effects. The presence of significant right ventricle dysfunction and marked hypoxemia should prompt re-evaluation of the need for elective surgery. Obesity hypoventilation syndrome is even harder to recognize preoperatively as arterial blood gases are generally not obtained prior to elective noncardiac surgery. Amongst patients with obstructive sleep apnea this group of patients carries much higher risk of postoperative respiratory and congestive heart failure.
