MISSION of CARE

In June, when the Children's Hospital of Diamniadio in Dakar, Senegal, received a 4-year-old who had swallowed a whistle by accident about 20 days earlier, Cai Zhiliang, a doctor, knew urgent surgery was needed.

The child was coughing while wheezing, and the oxygen-saturation level had dropped to 70 percent.

It was a common surgery, but the lack of proper medical equipment made the situation a little difficult. Cooperating with anesthesiologist Huang Jianbin and physician Guo Lianghua, Cai removed the whistle from the child's windpipe in about 20 minutes.
