Errors in prescriptions are common phenomena in prescriptions produced by clinicians. With development and application of information technology in medical fields, electronic prescription system has been regarded as the best resolution for effective prevention of errors in prescriptions. A retrospective study of the prescriptions made by the electronic prescription system of the hospital studied over one year showed that this system could reduce errors easily made in manual prescriptions significantly, but it failed to reduce the errors related to dosages. Those dosage-related errors were mainly caused by change of physician prescribing behavior and defective man-machine interaction. Electronic prescription system, though functions basically, can not avoid prescription errors effectively, which poses a potential threat to safe use of medicines in patients. It is urgent at the moment to perfect the functions of electronic prescription system, promote a friendly man-machine interaction and reduce errors made by system errors.

Human infection with avian influenza A (H7N9) is easy to induce severe acute respiratory distress syndrome (ARDS), and traditional mechanical ventilation cannot correct hypoxemia, so patients may die from multiple organ failure (MOF) caused by persistent hypoxia. Extracorporeal membrane oxygenation (ECMO) can provide effective respiratory support and win time for the treatment of severe H7N9. The first case of severe H7N9 in Guangdong Province in 2018 was admitted to Zhongshan Hospital Affiliated to Sun Yat-sen University. The case was insult with severe ARDS caused by H7N9, the traditional mechanical ventilation could not correct hypoxemia, and the lung condition gradually improved with ECMO assistance. After 13 days of ECMO support, the patient was successfully weaned from ECMO and was transferred to a general ward after 55 days. After 102 days of rehabilitation, the patient was discharged from hospital and followed up for 2 months, who was in good health and had a good quality of life. This article states the diagnosis and treatment of severe H7N9 in details, providing experience for the treatment of severe H7N9 in the future.
