AMBU Ventilation is an important part in resuscitation of an apnoeic person or a person who is not breathing. The AMBU of an AMBU bag is an abbreviation for ‘Artificial Manual Breathing Unit’. The AMBU bag is used to ventilate the patient. An AMBU Ventilation unit consists of one self inflating bag made up of […]
The aim of the airway device is to prevent the tongue fail. The tip of airway gets inserted between tongue and posterior pharyngeal wall and thus prevents the tongue failing back on posterior pharyngeal wall. The various usages of the airway device are: As an alternative to intubation where difficult intubation is anticipated. Securing airway in
Unstable pelvic fractures include disruption of the ring anteriorly at the symphysis pubis or through a pubic bone and are broadly categorized into three types: anterior-posterior open book pelvic fracture, lateral compression fracture, and vertical shear malgaigne pelvic fracture. Pelvic fractures from blunt force trauma are broadly categorized as either stable or unstable based on

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
Common health effects of carbon dioxide include : • There is fall in peripheral vascular resistance but there is increase in mean arterial pressure. There is increase in blood flow towards skin and so more chances of oozing. • Directly it reduces contractile force of heart but indirectly increases cardiac output. It increases the sympathetic
Carbon dioxide was discovered by Von Helmont and was isolated by Joseph Black in 1757. Physical properties of carbon dioxide were shown by Yandell Henderson in 1925 and J S Haldane in 1926. It was frequently used to stimulate respiration and there was provision for carbon dioxide cylinders on old Boyle’s machines. The physical properties of
Despite the great strides made over the last decades in improving survival after thermal injury, infectious complications remain an important cause of morbidity and mortality. Nearly 50% of all burn deaths are related to infected burn. Several factors contribute to the high incidence and severity of infection in burn patients. First, a profound immune suppression
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.

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
There are numerous uses of carbon dioxide in modern anesthesia. It is used : • To increase depth of anesthesia with volatile anesthetic agents by stimulating respiration.- • To increase cerebral blood flow during carotid artery surgery. • To produce hyperventilation during blind nasal intubation. • To stimulate the respiration after artificial hyperventilation. • It
