RESUMEN
Endotracheal tube suctioning [ETS] is a painful and invasive procedure. Studies have shown that the performance of nurses in this procedure is weak, so we conducted a study to evaluate the effect of ETS education for nurses on neonates' pain in neonatal intensive care units [NICUs]. In a quasi-experimental study, performance of 25 nurses working in NICU was assessed before and after ETS education by a checklist. In addition pain score of 50 neonates was measured using pain assessment tool [PIPP] one minute before, during and 5 minutes after ETS. The neonates had a gestational age of less than 37 weeks and were intubated [at least for 8 hours and up to 24 hours] A P.value of less than 0.05 was considered as statistically significant. Mean scores of nurses' performance were significantly different before and after education [P
