Closure of tympanic membrane perforations by chemical cautery
Abstract:
Fifty cases of dry, central, tympanic membrane perforation were studied for closure by application of saturated solution of trichloracetic acid. Aetiologically 17 cases belonged to traumatic and 33 to the inflammatory group. Eustachian tube patency and good air-bone gap on audiometry were the pre-requisites. Study concluded with 78% success with average of 2.8 applications. The patients had definite improvement in the hearing acuity and relief from other symptoms. The study highlights the achievements by using this old method.

01:30Methods of Sterilization II: Chemical Methods
In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
