sqadia.com aims to polish the wings of medical students so that they can fly high in the medical world with the help of hundreds of medical video lectures. This full length lecture discloses information about ¨deaths in surgical procedure and barotrauma¨. At first, death during surgery is discussed with the help of medical definition. Then classification system for deaths during surgery is discussed in which five categories of classification system are highlighted. After that, some of the leading cause of death associated with anaesthesia are elaborated. To conclude, Dr. Hina Khan demonstrates dysbaric fatalities and barotrauma and the autopsy findings.
Deaths During Surgery
Deaths associated with surgery are deaths that occur during or within a short time after surgical operation, invasive diagnostic procedure or an anaesthetic. Death has occurred and the next step is to carry out autopsy to investigate the exact cause but in these kind of deaths morphological findings are very minimal. Surgical devices should not be removed before autopsy because their placement and patency need to be checked for proper investigation. Autopsy procedure exclude natural disease or drug involvement.
Mode and Cause of Death
Mode and cause of death can be a disease or injury for which operation or anaesthetic was being carried out, any other disease, or complication of surgical procedure. Classification system for deaths during surgery is divided into 5 categories. ASA1 classification system represents that heir is no serious disease. ASA2 refers to the serious disease but have limitations on their activities. In ASA3, there is a serious disease and have some limitations of their activities. Similarly, ASA4 and ASA5 are discussed respectively in the medical video lecture at sqadia.com.
Deaths Associated with Anaesthesia
Cardiac arrest, hypoxia, respiratory failure, airway obstruction, regurgitation of gastric contents are some of the leading cause of death which occur after taking anaesthesia. Some of the hazards of local and epidural anaesthesia highlighted by the forensic practitioner are direct nerve damage, spinal haematoma, spinal infection, drug error. Malignant hyperthermia is defined as a rare, pharmacogenetic disorder of the skeletal muscle, which is triggered by halogenated volatile anaesthetics.
Dysbaric Fatalities and Barotrauma
Dysbarism or dysbaric illness cover a broad range of complex pathophysiological conditions associated with decompression, while barotrauma describes the mechanical damage from gas released into the tissues. Diving poses various risks that can be due to impact of environmental conditions, concomitant morbidity, potential hazards. rapid decompression leads to bubble formation. Bubbles can cause venous stasis, obstruct vessels and cause ischaemic injury of the tissues.
Autopsy in Dysbarism and Barotrauma
External findings of autopsy include skin color, hypothermia, bright pink color of the body recovered from water. The brain should be removed before opening the body cavities, using a special technique to detect air in the cerebral arteries. In the central nervous system, petechial haemorrhages may be seen in any part of the system, including the spinal cord. To know more about autopsy findings, watch detailed lecture on sqadia.com.
