A woman in the third trimester of pregnancy is predisposed to supine hypotension syndrome in pregnancy while in the supine or sitting position due to the hemodynamic and anatomic changes of pregnancy.

Unfractionated heparin is a mixture of different weights of heparin (5 to 30k) that have varying effects on factors IIa, IXa, and Xa. Low-molecular-weight heparin (LMWH) is a subset of heparin (weight ~5k) that has activity on factor Xa, but not on IIa. LMWH has the advantage of less binding to protein and dose-independent clearance.

The principal options for Cerebral vasospasm treatment and treating delayed cerebral ischaemia are haemodynamic augmentation and endovascular therapy. Alternative therapies include intra-aortic counter pulsation (IABC), therapeutic hypothermia dedicated Cerebral vasospasm treatment and barbiturate coma. The concept of haemodynamic augmentation – also referred to as hypertension, hypervolemia, hemodilution or triple-H therapy—in patients with aneurysmal subarachnoid haemorrhage
Heterotopic ossification may occur following head or spinal cord trauma, burns, or major surgery on the musculoskeletal system. A heterotrophic bone may cause severe physical impairment by surrounding a joint such as the hip or the elbow and fixing the joint in a nonfunctional position (i.e., contracture). Heterotopic ossification is also very common following open
Extubation is the process of removal of an Endotracheal tube from a patient. A person is usually put on endotracheal tube if he is unconscious so as to protect his airways or to ventilate the person if he is not breathing adequately. Intubation is also the best method to secure an airway even in the
