A quantitative and descriptive research design was used for the study to investigate emergency equipment, essential drugs and emergency trolleys. A convenient sample of 10 emergency trolleys in the Windhoek Central Hospital (Hospital A) and Katutura Intermediate Hospital (Hospital B) in Windhoek, Namibia were used. Data was collected using a checklist adapted and edited from the EMSSA. Data were analysed using Microsoft excel 2013. Essential paediatric equipment including bag valve mask devices, Magill’s forceps, oxygen masks were absent in many of the units and wards. Data described that checking of defibrillators, monitors and suction devices still remained a major problem in the units/wards that were fortunate enough to have the aforementioned equipment. A conclusion was that generally the units/wards performed well during the assessments and evaluations. There were still units without emergency trolleys, trolleys that were poorly assessed, and those that were obstructed and registered nurses that had a negative perception to the audit of the emergency trolley. Specialized units such as NICU and Hi-Care Hospital A and Prem Unit Hospital B performed very well in their assessments. Development of policy with regards to assessing, restocking and maintenance of emergency supplies can be used to guide the nurses on what to do. Resuscitation morbidity and mortality meetings in order to identify issues and outcomes surround resuscitation incidences within the unit or ward.展开更多
