For 50 patients requiring surgical care in emergency situations assuming 2 operations per patient (100 interventions) WHO trauma and emergency surgery kit (TESK) aims to provide materials and drugs to meet the needs of 50 patients requiring surgical care in emergency situations, assuming an average of two operations per patient. This kit is intended for use by health care providers who are trained in appropriate management of emergent surgical issues and are acting within their scope of practise. It is designed for use in areas where basic levels of infrastructure exist. The composition of TESK has recently been revised in collaboration with the International Committee of the Red Cross to meet the dynamic requirements of emergency situations. In general, this kit contains oral and IV medicines including cold chain drugs and medical supplies including renewables and instruments. WHO TESK is intended to provide the resources needed for surgical procedures in operating theatres. Some of the sub-units may be used for simpler procedures that may occur in other parts of the facility.
