Does preoperative PT/PTT screening predict postoperative hemorrhage in pediatric patients undergoing tonsillectomy?
Does preoperative PT/PTT screening predict postoperative hemorrhage in pediatric patients undergoing tonsillectomy?
Routine preoperative PT/PTT screening provides no additional predictive value for postoperative hemorrhage beyond a clinical bleeding history in pediatric patients undergoing tonsillectomy.
No takes yet. Share an insight, caveat, or question.
Preoperative PT/PTT testing does not identify higher bleeding risk in pediatric tonsillectomy; leaves open value of history-guided selective screening.
HOWELLSII et al. (1997) studied this question.
