You can file a complaint with the state's medical licensing board, but there is no other effective recourse. The problem you face is that medical malpractice suits are very expensive--even if you were to be your own attorney (whcih is *not* recommended), you MUST hire a medical expert in an appropriate discipline (such as a pain management doctor) to render an opinion, write a report, and if necessary testify in court: only a medical expert's testimony is considered about whether this was malpractice and the consequences thereof. But if your daughter, as we hope, did not suffer provalel lasting harm from this, then the amount of compensation she might get for 16 hours of post operative pain is likely less thant the many hundren or several thousand dollar cost of hiring the medical expert.
