Mid-stream clean catch urine collection in newborns: a non-invasive and safe technique

Rajendra Kumar, Nithin ., Sudha Rudrappa

Abstract


Background: The aim of this study is to determine the success rate and safety of a non-invasive technique to obtain clean-catch midstream urine samples in newborns.

Methods: Prospective bedside clinical study. After obtaining written informed consent,120 consecutive newborns admitted in NICU with no dehydration, poor feeding, need for immediate urine sample by invasive method  for whom urine collection was advised for various reasons who met the inclusion criteria were included in the study with consent being taken from the parents. After adequate milk intake supra pubic and lumbar para vertebral areas were stimulated in repeated cycles of 30 s until micturition began.

Results: Success rate in obtaining a midstream urine sample within 5 min. The success rate was 90%. The mean time taken to collect urine was 64.24s, for males it was 62.55s and for females 65.93s.

Conclusions: The technique has been demonstrated to be safe, quick and effective. The discomfort and time consumption usually associated with bag collection methods as well as invasive techniques can be avoided.
